Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of LED lighting devices, in particular to an LED lighting lamp. BACKGROUND

[0002] The LED lighting lamp refers to a lamp with light-emitting diodes as light sources, which is widely used because of its energy-saving, long service life and other advantages. The flat panel lamp in the LED lighting lamp is a lighting lamp that can be embedded in the ceiling, which is favored by people because of its lightness, large irradiation area and other characteristics.

[0003] The flat panel lamp in the prior art usually sets the light source in the middle area of the flat panel lamp, and irradiates light to the indoor environment through the light-emitting surface corresponding to the middle area. The disadvantage of this flat panel lamp is that there is only one light-emitting surface, and the light in the indoor environment is not uniform, for example, the middle area of the indoor environment is too bright and the peripheral area is relatively dark.

[0004] In order to solve the problem of non-uniform light, the market increases the bat-wing diffusion film to realize the bat-wing light distribution of the light source. This bat-wing diffusion film is a diffusion film with a special micro-prism surface structure, which has high cost and poor visual effect. Moreover, the bat-wing diffusion film needs to be fixed by using a transparent plate as support due to its double-sided microstructure. In order to form a bat-wing light pattern, the bat-wing diffusion film also needs to be designed according to the position and curvature of the light-emitting surface of the light source in use. Therefore, the structure design of the lamp is also relatively complex.

[0005] In addition, in the prior art, the light source is arranged in the middle area, and the light-emitting angle of the lamp bead is limited, which causes the light-emitting surface to be non-uniformly irradiated, thereby further causing some areas (especially the peripheral areas) on the chassis of the flat panel lamp to have no light irradiation and appear dark. In order to solve the problem of dark area, the market generally changes the light emission direction of the lamp bead by increasing the lens. However, this way increases the lens structure, making the structure design of the flat panel lamp complex and the appearance not beautiful.

[0006] In the prior art, the lampshade is usually connected to the lamp body after the overall structure of the lamp body is assembled, and the connection is not stable enough.

[0007] In summary, in view of the deficiencies and shortcomings of the flat panel lamp in the prior art, how to design the flat panel lamp to form a uniform light pattern and / or avoid dark areas and improve the reliability of the lamp is a technical problem that the technical personnel of the present application urgently need to solve.

[0171] The advantages and effects of the present application can be easily understood by those skilled in the art from the content disclosed in the present specification.

[0172] In the following description, reference is made to the accompanying drawings which form a part hereof, and in which are shown several embodiments of the present application. It is understood that other embodiments can be utilized and structural or operational changes can be made without departing from the scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of various embodiments of the present application are defined by the appended patent claims. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0173] It will be understood that, although the terms first, second, etc. can be used herein to describe various elements or parameters, these elements or parameters should not be limited by these terms. These terms are only used to distinguish one element or parameter from another element or parameter. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the various described embodiments. Both the first element and the second element are a first element in that they are the first elements described, but there is only one of them. As used herein, the terms "or" and "and / or" are construed to include both the inclusive and exclusive or, unless explicitly indicated otherwise. Thus, "A, B, or C" or "A, B, and / or C" means any of the following: A; B; C; A and B; A and C; B and C; A, B, and C. The exception to this is when there are expressions such as "only one of A and B" in which case "A or B" does not include A and B when A and B are expressly presented with "only one of."

[0174] It will be understood that when an element such as a layer, region, or substrate is referred to as being "on" or extending "over" another element, it can be directly on or extend directly over the other element or intervening elements can also be present. In contrast, when an element is referred to as being "directly on" or extending "directly over" another element, there are no intervening elements present. It will also be understood that when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can be present. In contrast, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present.

[0175] Relative terms such as "below" or "above" or "upper" or "lower" or "horizontal" or "vertical" can be used herein to describe a relationship of one element, layer, or region to another element, layer, or region as illustrated in the figures. It will be understood that these terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. In the present application, the term "vertical", "horizontal", "parallel", are defined as including ±10% on the basis of standard definitions. For example, vertical generally means an angle of 90 degrees to a reference line, but in the present application, vertical means including 80 degrees to 100 degrees.

[0176] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising", when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0177] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms used herein should be interpreted as having a meaning that is consistent with their meaning in the context of this specification and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. For example, the term "support" as employed in describing some embodiments can also be understood as "supporting".

[0178] Comparative numerical terms such as "less than" and "greater than" are intended to encompass the concept of equality unless specifically stated otherwise. As an example, "less than" can mean not only the strict mathematical sense of "less than", but also "less than or equal to".

[0179] The present application discloses, in some embodiments, an LED lighting fixture, which can be a suspended lighting fixture, or a fixed lighting fixture mounted to a ceiling or a suspended ceiling. Depending on the application, the LED lighting fixture disclosed in the present application can also be referred to as a flat panel light, a pendant light, a recessed light, a concave light, an embedded light, or a ceiling recessed light, etc.

[0180] Please refer to FIGS. 1-3 , FIG. 23 , and FIG. 36 , FIG. 1 A front view schematic diagram of an LED lighting fixture in an embodiment of the present application is shown,FIG. 2 Fig. 1 shows a left side view of an LED lighting fixture according to an embodiment of the present application, FIG. 3 , FIG. 23 , and FIG. 36 Fig. 1 shows a perspective view of an LED lighting fixture 100 according to an embodiment of the present application. As shown in the figure, the LED lighting fixture comprises a support unit 1 and a photoelectric module 2 connected to the support unit 1. In some examples, the photoelectric module 2 is connected to the support unit 1 in a replaceable (detachable) manner, so that it can be quickly detached and replaced relative to the LED lighting fixture 100. If the photoelectric module 2 is damaged, only the photoelectric module 2 part can be replaced, which can reduce the replacement cost and reduce the maintenance time compared to replacing the entire lamp. The photoelectric module 2 can also be connected to the support unit 1 in a non-detachable manner, that is, after the photoelectric module 2 is fixed to the support unit 1, it cannot be easily detached. In other examples, the photoelectric module 2 can be configured to be quickly installed with the support unit 1, and after installation, the photoelectric module 2 and the support unit 1 cannot be easily detached. In this way, when packaging and transporting, the photoelectric module 2 and the support unit 1 can be packaged and transported separately, saving packaging and transportation costs, and when selling or using, the photoelectric module 2 and the support unit 1 can be quickly installed.

[0181] Please refer to Figs. 1 to FIG. 4 , FIG. 4 Fig. 1 shows a perspective view of a support unit according to an embodiment of the present application. As shown in the figure, the support unit 1 comprises a base 11. In the embodiments shown in Figs. 1 and FIG. 2 , and FIG. 4 , the support unit 1 further comprises a back plate 12, which is arranged around the base 11, or, as can also be described, the back plate 12 is formed by the base 11 extending outwardly to the periphery. In some embodiments, this back plate can also be referred to as a side wall of the LED lighting fixture. The back plate 12 is arranged around the base 11 and forms a containing space with the base 11. Please refer to FIG. 2 , FIG. 5 , FIG. 9 , a rectangular coordinate system is established, with the plane of the bottom plate 111 as the XY plane and the direction perpendicular to the bottom plate as the Z axis. In this embodiment of the present application, a direction along the first light emitting assembly 211 is the X axis, and a direction perpendicular to the first light emitting assembly 211 is the Y axis. The back plate 12 can be arranged inclined or horizontally relative to the base 11. For example, the inclination angle (such as the angle in FIG. 2 ) between the back plate 12 and the base 11 can be set to 0 to 90 degrees, such as FIG. 2As shown, the inclination angle refers to the angle between the back plate 12 and the horizontal section X of the base 11, and in more specific examples, the inclination angle between the back plate 12 and the base 11 can be 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, 20 degrees, 21 degrees, 22 degrees, 23 degrees, 24 degrees, 25 degrees, 26 degrees, 27 degrees, 28 degrees, 29 degrees, or 30 degrees, and preferably, the inclination angle can be set to 20 degrees.

[0182] In an embodiment, the base 11 is located in the middle region, and the area of the base 11 covering the front surface of the support unit 1 accounts for 15% to 50% (for example, it can be about 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 30%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, or 50%) of the area of the front surface of the support unit 1, where the area of the front surface refers to the projected area in the direction perpendicular to the support unit 1 (where the direction perpendicular to the support unit 1 is defined as the horizontal direction, such as FIG. 2 The middle section X is the horizontal section). Considering that in some embodiments, the optoelectronic module 2 at least includes a light-emitting unit, which is arranged on the base 11, it can also be understood that in the support unit 1, the area of the front surface for the light-emitting region accounts for 15% to 50% of the area of the front surface of the support unit 1. More specifically, considering the material cost and the appearance aesthetics, the area of the front surface of the base 11 covering the support unit 1 is set to about 33.3% (33.3% can be understood as an approximate value of 1 / 3) of the area of the front surface of the support unit 1.

[0183] Please refer to FIG. 1 , FIG. 3 , FIG. 5 , FIG. 24A , and FIG. 37 , FIG. 5 , FIG. 24A , and FIG. 37 respectively show the split structure of the LED lighting lamp in an embodiment of the present application, such as FIG. 5As shown, the optoelectronic module 2 comprises a light emitting unit 21 and a light processing unit 22, the light emitting unit 21 is configured to emit light rays for illumination, and the light processing unit 22 is configured to process the light rays emitted by the light emitting unit 21 before emitting the light rays. For example, the light processing unit 22 can change the light path of the light emitting unit 21, i.e. the light processing unit 22 is arranged on the light path of the light emitting unit 21. The base 11 of the support unit 1 provides at least a mounting position for the light emitting unit 21, in other words, at least part of the light emitting unit 21 is arranged on the base 11 or in the accommodating space formed by the base 11. In this application, the side of the support unit 1 for arranging the light emitting unit 21 is defined as the front side, and the side opposite to the front side is defined as the back side. The base 11 can also provide a mounting position for the light processing unit 22, in other words, the light processing unit 22 can also be arranged on the base 11 or in the accommodating space formed by the base 11. Of course, in other embodiments, the base 11 can also provide a mounting position or an accommodating space for other components, units, modules, modules or members in the optoelectronic module 2. It should be understood that, FIG. 5 For example, in some embodiments, the optoelectronic module 2 can not be provided with the light processing unit 22.

[0184] Please refer to FIG. 6 and FIG. 7 , FIG. 6 The figure shows the three-dimensional structure of the light emitting unit in an embodiment of the application, FIG. 7 The figure shows the three-dimensional structure of the light emitting unit in an embodiment of the application, as shown, the base 11 of the support unit 1 has a bottom plate 111, the light emitting unit 21 comprises at least one first light emitting assembly 211, the at least one first light emitting assembly 211 is arranged on the bottom plate 111, the first light emitting assembly 211 can comprise a first circuit board 2111 and at least one first light emitting body 2112 arranged on the first circuit board. Among them, the first light emitting body 2112 can be a LED lamp bead, or other types of LED light emitting unit. The first circuit board 2111 is attached (for example, directly attached or attached through an intermediate medium) to the bottom plate 111, and the first light emitting body 2112 can be arranged in multiple, the multiple first light emitting bodies 2112 are uniformly or partially uniformly distributed on the first circuit board 2111, the 2112 on the adjacent first light emitting assembly 211 can be arranged in alignment or staggered with each other, FIG. 6 and FIG. 7 In the first light emitting body 2112 is arranged as an example of 24, those skilled in the art can also arrange any number of first light emitting bodies 2112 according to actual needs. In some embodiments, the first light emitting assembly 211 can be arranged as at least two groups, i.e. the light emitting unit 21 has at least two groups of light emitting assemblies, at least two groups can be understood as two groups and more groups, each group is arranged in parallel on the bottom plate 111, for example, the first light emitting assembly 211 can be arranged as 2 groups, 3 groups, 4 groups, 5 groups or 6 groups, etc.FIG. 6 and FIG. 7 In the embodiment shown in FIG. 11, the first light emitting assembly 211 is arranged in four groups. Of course, in other embodiments, such as in some specific installation environments or under the restrictions of the lamp structure, the first light emitting assembly 211 can also be arranged in only one group. In other words, those skilled in the art can select any number of groups according to actual needs based on the inspiration of the above-mentioned embodiments of the present application and arrange them on the bottom plate 111. In another embodiment, the spacing distance between the first light emitting bodies 2112 is at least two.

[0185] In another embodiment, the first light emitting assembly 211 can be arranged in at least two groups, and adjacent first light emitting assemblies 211 are not parallel, that is, the extension lines of the side lengths of adjacent first light emitting assemblies 211 intersect, or in other words, the spacing distance between adjacent first light emitting assemblies 211 is at least two.

[0186] Please refer to FIG. 6 and FIG. 8 , FIG. 8 The light pattern of the first light emitting assembly in an embodiment of the present application is shown in FIG. 11. As shown in the figure, the light pattern of the first light emitting assembly 211 has the strongest light intensity at an exit angle of 0 degrees, and the light intensity continuously decreases with the increase of the exit angle. For example, the light pattern distribution of the first light emitting assembly 211 is Lambertian or near Lambertian. In the example in which the light emitting unit 21 only includes the first light emitting assembly 211, the light pattern distribution of the LED lighting lamp is also the light pattern distribution of the first light emitting assembly 211. In this way, the illumination of the LED lighting lamp is not uniform, and the light emitting intensity is higher in the area directly below the first light emitting assembly 211. When applied to the space to be illuminated, the central spot phenomenon of the LED lighting lamp in which the middle area of the space is brighter and the peripheral area is darker will occur.

[0187] The area directly below the first light emitting assembly 211 mentioned here and hereinafter can be understood as the area of the preset beam angle of the first light emitting assembly 211. In some examples, the preset beam angle can be set to 10 degrees to 60 degrees (for example, it can be about 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, 20 degrees, 21 degrees, 22 degrees, 23 degrees, 24 degrees, 25 degrees, 26 degrees, 27 degrees, 28 degrees, 29 degrees, 30 degrees, 31 degrees, 32 degrees, 33 degrees, 34 degrees, 35 degrees, 36 degrees, 37 degrees, 38 degrees, 39 degrees, 40 degrees, 41 degrees, 42 degrees, 43 degrees, 44 degrees, 45 degrees, 46 degrees, 47 degrees, 48 degrees, 49 degrees, 50 degrees, 51 degrees, 52 degrees, 53 degrees, 54 degrees, 55 degrees, 56 degrees, 57 degrees, 58 degrees, 59 degrees, or 20 degrees). For example, when the preset beam angle is set to 10 degrees, the area directly below the first light emitting assembly 211 refers to the area within the range of -5 degrees to 5 degrees with the beam center line (i.e., the main axis of the maximum light intensity) as the 0-degree angle. In some examples, the preset beam angle can also be set with light intensity as the reference. The preset beam angle can be set to the included angle of 20% maximum light intensity to the included angle of 60% maximum light intensity. For example, when the preset beam angle is set to the included angle of 20% maximum light intensity, the area directly below the first light emitting assembly 211 refers to the included angle area of the two beams with light intensity equal to 20% maximum light intensity. It should be understood that in the embodiment in which the first light emitting assembly 211 is arranged in the middle region of the LED lighting lamp, the area directly below the first light emitting assembly 211 can also be referred to as the middle region of the LED lighting lamp or the area directly below the LED lighting lamp. The subsequent description will not be repeated.

[0188] The circumferential region (for example, the front and rear sides on the left and right, also referred to as the peripheral region) of the first light emitting assembly 211 mentioned here and hereinafter can be understood as the peripheral region of the area directly below the first light emitting assembly 211. In this application, the circumferential region and the area directly below the first light emitting assembly 211 can have a certain range of overlap at the joint. With respect to the position of the first light emitting assembly 211, the circumferential region of the first light emitting assembly 211 includes the front region, the rear region, the left region, the right region, etc. In some embodiments, this application directly uses the circumferential region when it does not specifically indicate a certain direction (for example, front, rear, left, and right). It should be understood that in the embodiment in which the first light emitting assembly 211 is arranged in the middle region of the LED lighting lamp, the circumferential region of the first light emitting assembly 211 can also be referred to as the circumferential region of the LED lighting lamp. The subsequent description will not be repeated.

[0189] In view of the above FIG. 8and the central light spot as described in the description, in some embodiments, the light emitting unit 21 can further comprise a second light emitting component 212, aiming to design the structure and / or parameters of the support unit and / or the optoelectronic module in the LED lighting fixture, so that the light distribution of the LED lighting fixture is formed by the combination of the light distribution of the first light emitting component 211 and the second light emitting component 212, thereby eliminating the central light spot phenomenon as described in FIG. 6 、 FIG. 8 , and the description, and greatly improving the illumination uniformity of the LED lighting fixture. More specifically, in some embodiments, by setting the relative positions of the first light emitting component and the second light emitting component, and / or by diversifying the light emitting angles, i.e., by setting at least two light emitting components with at least two light emitting angles, the light emitting unit 21 is made to have at least two light emitting angles, so that the light distribution of the LED lighting fixture formed by the combination of the light distributions of the two is relatively uniform, such as a bat-wing light distribution or a near-bat-wing light distribution. Among them, the bat-wing light distribution refers to a light distribution that spreads to both sides like a bat wing, with the light intensity in the middle region (i.e., the region with smaller exit angle) being slightly lower, and the light intensity in the two side regions (i.e., the region with larger exit angle) being slightly higher. The near-bat-wing light distribution refers to a non-ideal bat-wing light distribution, although it does not present the standard case of slightly higher light intensity on both sides on the light distribution, but the overall light distribution presents a case where the light intensity in the middle and the two sides is not much different, or in other words, the difference is within the acceptable range of uniformity. The bat-wing light distribution or the near-bat-wing light distribution can help the lamp to achieve high-uniformity lighting, and enable two lamps to be installed at a greater distance from each other.

[0190] In an embodiment, please refer to FIG. 5 、 FIG. 7 , and FIG. 9 , FIG. 9As shown in the perspective view of the cooperation between the light emitting unit and the supporting unit in an embodiment of the present application, the second light emitting assembly 212 is arranged on the base 11 and on the periphery of the first light emitting assembly 211 and is arranged obliquely relative to the first light emitting assembly 211. Here, the periphery of the first light emitting assembly 211 refers to the periphery of the area occupied by the first light emitting assembly 211, and in the case where the first light emitting assembly 211 is arranged in multiple groups, the periphery refers to the periphery of the area occupied by the first light emitting assembly 211 as a whole, such as the periphery of the bottom plate 111. With the light emitting direction as the reference, the oblique arrangement of the second light emitting assembly 212 relative to the first light emitting assembly 211 refers to the light emitting side of the second light emitting assembly 212 being inclined toward the light emitting side of the first light emitting assembly 211, or in other words, the optical axis (or the extension line of the optical axis) of the first light emitting assembly 211 and the second light emitting assembly 212 intersecting. In other words, the light emitting of the second light emitting assembly 212 is mainly distributed in the peripheral area of the first light emitting assembly 211. That is, if the first light emitting assembly 211 contributes to the light intensity of the middle area of the LED lighting lamp, the second light emitting assembly 212 mainly contributes to the light intensity of the peripheral area of the LED lighting lamp, thereby greatly improving the uniformity of the light intensity distribution of the LED lighting lamp and avoiding the phenomenon of central light spot. Of course, in other embodiments, the first light emitting assembly 211 and the second light emitting assembly 212 can also be arranged in a spaced-apart or close-together manner.

[0191] As shown in FIG. 7 , the second light emitting assembly 212 can include a second circuit board 2121 and at least one second light emitting body 2122 arranged on the second circuit board 2121. The second light emitting body 2122 can be an LED lamp bead or other types of LED light emitting units. The second circuit board 2121 is attached (such as directly attached or attached through an intermediate medium) to the base 11, and the second light emitting body 2122 can be arranged in multiple numbers, and the multiple second light emitting bodies 2122 are uniformly distributed on the second circuit board 2121, FIG. 7 and FIG. 9 In the above embodiment, the first light emitting body 2122 is arranged in 24 numbers as an example, and a person skilled in the art can arrange any number of second light emitting bodies 2122 according to actual needs. In some embodiments, the second light emitting assembly 212 can also be arranged in multiple groups, and each group is arranged obliquely around and relative to the first light emitting assembly 211 on the periphery of the first light emitting assembly 211.

[0192] In another embodiment, the second light emitting body 2122 can be arranged non-uniformly on the second circuit board 2121. The second light emitting bodies on adjacent second light emitting assemblies 212 are arranged in a staggered manner.

[0193] In some embodiments, the second light-emitting component 212 can be tilted relative to the first light-emitting component 211 by making the mounting surface of the second light-emitting component 212 form a certain angle with the mounting surface of the first light-emitting component 211.

[0194] Please see FIG. 2 , FIGS. 9-11 , FIG. 10 This application is displayed. FIG. 9 A partial enlarged view of the base and light-emitting unit in the illustrated embodiment. FIG. 11 The figure shows a cross-sectional view of the LED lighting fixture along the X-axis in one embodiment of this application. As shown, the base 11 further includes a first base sidewall 112. That is, the base 11 has a base plate 111 and a first base sidewall 112. The first base sidewall 112 extends from the edge of the base plate 111 toward the light-emitting direction (i.e., the front direction of the support unit 1). The first base sidewall 112 has a first tilt angle β relative to the base plate 111 and is disposed around the base plate 111. A first light-emitting component 211 is disposed on the base plate 111 (i.e., the base plate 111 can be understood as the mounting surface of the first light-emitting component 211), and a second light-emitting component 212 is disposed on the first base sidewall 112 (i.e., the first base sidewall 112 can be understood as the mounting surface of the second light-emitting component 212), such that the tilt angle of the second light-emitting component 212 relative to the first light-emitting component is the first tilt angle β. The first base sidewall 112 can be configured in multiple groups, and the second light-emitting component 212 can also be configured in multiple groups corresponding to the number of first base sidewalls 112, so as to emit light in different directions. For example, the base plate 111 of the base 11 is configured as a polygon, and the base 11 has multiple groups of first base sidewalls 112 corresponding to the number of sides of the polygon, with a second light-emitting component 212 correspondingly disposed on each group of first base sidewalls 112. FIGS. 9-11 In the embodiment shown, the base plate 111 of the base 11 is quadrilateral, and the base 11 has 4 sets of first base sidewalls 112. A second light-emitting component 212 is correspondingly arranged on each set of first base sidewalls 112. The base plate 111 and the first base sidewalls 112 form a base plate accommodating space, and at least a portion of the optoelectronic module 2 is disposed in the accommodating space.

[0195] In order to make the light intensity distribution of the LED lighting lamp 100 meet the uniformity requirement, the first inclination angle β of the first base side wall 112 relative to the bottom plate 111 is set to 15 degrees to 45 degrees (for example, it can be about 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, 20 degrees, 21 degrees, 22 degrees, 23 degrees, 24 degrees, 25 degrees, 26 degrees, 27 degrees, 28 degrees, 29 degrees, 30 degrees, 31 degrees, 32 degrees, 33 degrees, 34 degrees, 35 degrees, 36 degrees, 37 degrees, 38 degrees, 39 degrees, 40 degrees, 41 degrees, 42 degrees, 43 degrees, 44 degrees, or 45 degrees). If it is less than 15 degrees, the first light emitting assembly 211 and the second light emitting assembly 212 will emit light in a manner close to being on the same plane (for example, the horizontal cross section X in FIG. 11 ), which will cause the light emitted by the second light emitting assembly 212 to be more dispersed than the light emitted by the first light emitting assembly 211, for example, the light emitted by the second light emitting assembly 212 is mainly distributed on one side at a certain distance from the light emitted by the first light emitting assembly 211. This not only cannot improve the uniformity of the light of the LED lighting lamp, but even can cause multiple light spots in the lighting of the LED lighting lamp, which aggravates the non-uniformity of the light of the LED lighting lamp. If the first inclination angle β is greater than 45 degrees, one case (the first inclination angle β is too different from 45 degrees, for example, greater than 60 degrees) will cause most of the light emitted by the second light emitting assembly 212 to be directed towards the accommodating space formed by the support unit 1. Thus, it is easy to be blocked by some components, units, modules, members, etc. arranged on the support unit 1, for example, in the example shown in FIG. 5 , the light processing unit 22 is arranged on the light emitting unit 21, most of the light emitted by the second light emitting assembly 212 will be blocked by some components in the light processing unit 22 and then emitted after being processed by the light processing unit 22; another case (the first inclination angle β is not too different from 45 degrees, for example, less than 60 degrees) will cause most of the light emitted by the two light emitting assemblies (211, 212) to be gathered in the same area, which will not be able to enhance the uniformity of the light of the LED lighting lamp, and it is difficult to form a bat-wing light type or a near bat-wing light type. In the present embodiment, more preferably, the first inclination angle β can be set to 30 degrees to 45 degrees. The first inclination angle β set in this range can make the LED lighting lamp present a bat-wing light type or a near bat-wing light type. Further, in a specific example, the first inclination angle β can be set to 20 degrees.

[0196] It should be noted that in the embodiment with multiple groups of first base side walls 112, each group of first base side walls 112 as a whole expands towards the side of the bottom plate 111, like FIG. 10 and FIG. 11As shown, the first base side wall 112 has 4 groups, and the 4 groups of first base side wall 112 respectively spread to the front, back, left and right of the bottom plate 111, and respectively form a first inclination angle β with the bottom plate 111. Among them, the positions of the 4 groups of first base side wall 112 are respectively defined as front, back, left and right. Among them, as viewed from the viewing angle shown in the figure, the position of the first base side wall 112 on the upper side is defined as front, the position of the first base side wall 112 on the lower side is defined as back, the position of the first base side wall 112 on the left side is defined as left, and the position of the first base side wall 112 on the right side is defined as right. It should be understood that the figure shown is only an example, and each group of first base side wall 112 does not necessarily need to be provided with the same first inclination angle β, only the first inclination angle β of each group of first base side wall 112 relative to the bottom plate 111 is 15 degrees to 45 degrees.

[0197] Please refer to FIG. 12 and FIG. 13 , FIG. 12 shown in the embodiment of the present application, FIG. 11 shown in the embodiment of the present application, FIG. 13 shown in the embodiment of the present application, FIG. 11 shown in the embodiment of the present application, FIG. 12 In the left first base side wall 112, the second light emitting assembly 212 is provided, and the first light emitting assembly 211 is attached to the middle of the bottom plate 111. The principle of the light emitting of other groups of first light emitting assembly 211 and second light emitting assembly 212 is similar, which will not be described here. Among them, FIG. 13 shown is the light pattern formed by the combination of all first light emitting assemblies 211 and second light emitting assemblies 212. As shown, the light emitted by the first light emitting assembly 211 is mainly concentrated in the area directly below the first light emitting assembly 211, which is also called the middle area of the LED lighting lamp in some examples. The second light emitting assembly 212 located on the left side is inclined to the first light emitting assembly 211, and the light emitted by the second light emitting assembly 212 is mainly distributed in the left side area of the first light emitting assembly 211. Similarly, the light emitted by the second light emitting assembly 212 located on the right side should be mainly distributed in the right side area of the first light emitting assembly 211, the light emitted by the second light emitting assembly 212 located on the front side should be mainly distributed in the front side area of the first light emitting assembly 211, and the light emitted by the second light emitting assembly 212 located on the back side should be mainly distributed in the back side area of the first light emitting assembly 211, so that the light emitted by the second light emitting assembly 212 is mainly distributed in the peripheral area of the first light emitting assembly 211. As FIG. 12 and FIG. 13As shown, the first light emitting component 211 contributes to the light intensity of the middle region of the LED lighting fixture, and the second light emitting component 212 mainly contributes to the light intensity of the peripheral region of the LED lighting fixture, so that the light intensity difference between the middle region and the peripheral region of the LED lighting fixture is not large (for example, within the range of -40 degrees to 40 degrees, the light intensity difference is within the acceptable range of uniformity), greatly improving the uniformity of the light intensity distribution of the LED lighting fixture and avoiding the phenomenon of central light spot.

[0198] In some embodiments, as previously described, the optoelectronic module 2 can further include a light processing unit 22 for processing the light emitted by the light emitting unit 21. The light processing unit 22 is arranged on the base 11, and in order to provide a suitable accommodation space or position, in some embodiments, as shown in FIGS. 9-11 As shown, the base 11 further has a second base side wall 113 connected to the first base side wall 112 and having a second inclination angle γ relative to the first base side wall 112, in other words, the second base side wall 113 is formed by the first base side wall 112 being bent towards the light emitting direction (also referred to as the front direction of the support unit) and then continuing to extend. As shown in FIGS. 9-11 In the embodiment shown, the number of second base side walls 113 is consistent with the number of first base side walls 112, that is, the bottom plate 111 of the base 11 is arranged as a quadrilateral, the first base side wall 112 is arranged as 4 groups corresponding to the four sides of the quadrilateral, and the second base side wall 113 also has 4 groups. Of course, those skilled in the art can also design the number of second base side walls 113 to be different from the number of first base side walls 112 according to the actual shape design, which is not limited in the present application.

[0199] It should be noted that in some embodiments, the second base side wall 113 can also serve as a reflecting surface for the light emitted by the second light emitting component 212 to reflect the light with a larger emission angle of the second light emitting component 212 back to the peripheral region of the light emitted by the first light emitting component 211, as shown in FIG. 12 As shown, the light ray m is the light ray emitted by the left second light emitting component 112 reflected on the second base side wall 113, so that the second base side wall 113 can make the light emitted by the second light emitting component 212 more concentrated in the peripheral region of the light emitted by the first light emitting component 211, improving the uniformity of the light emitted by the LED lighting fixture.

[0200] In an embodiment, the light processing unit 22 comprises a light beam control component for changing the light emitting path of the light emitting unit to achieve better light emitting effect. In a specific example, the light beam control component is arranged at the light emitting side of the second light emitting component 212 for changing the path of at least part of the light emitted by the second light emitting component 212 so that the light emitted by the second light emitting component 212 is mainly distributed in the peripheral side area of the first light emitting component 211. For example, the light beam control component can change the light emitted by the second light emitting component 212, which is directed to the area right below the first light emitting component 211 or the middle area of the LED lighting lamp, to be directed to the peripheral side area of the first light emitting component 211 or the peripheral side area of the LED lighting lamp. The light beam control component can also gather the light emitted by the second light emitting component 212, which has an excessively large angle, to be directed to the peripheral side area of the first light emitting component 211, so that the LED lighting lamp can form a bat-wing light pattern or a near bat-wing light pattern, further improving the light emitting uniformity of the LED lighting lamp.

[0201] Please refer to FIG. 14 and FIG. 15 , FIG. 14 shows a cross-sectional structure schematic diagram of the LED lighting lamp according to the present application in an embodiment along the X-axis direction, FIG. 15 shows a cross-sectional structure schematic diagram of the LED lighting lamp according to the present application in an embodiment along the Y-axis direction, FIG. 14 As shown in the figure, the light processing unit 22 comprises a light beam control component 221, which comprises a sawtooth lens 2211 arranged at the light emitting side of the second light emitting component 212. The sawtooth lens 2211 can be arranged in a number corresponding to the second light emitting component 212. In the embodiment shown in the figure, the sawtooth lens 2211 has 4 groups corresponding to the number of the second light emitting component 212. FIGS. 14-15 The sawtooth lens 2211 is arranged in parallel with each second light emitting component 212 (in some embodiments, it can also be understood that the sawtooth lens 2211 is arranged in parallel with the first base side wall 112). The sawtooth lens 2211 is arranged in the form of a long strip extending in the length direction of the second light emitting component 212, so that the light emitted by each second light emitter of the second light emitting component 212 can pass through the sawtooth lens 2211 to change the light emitting path of the second light emitting component 212.

[0202] Each curved surface in the sawtooth lens 2211 faces away from the first light emitting component 211, for refracting part of the light emitted by the second light emitting component 212 to make the part of the light output at a wider angle (greater than the original emission angle), further making the light emitted by the second light emitting component 212 distributed on both sides of the first light emitting component 211, and hardly contributing to the area right below the first light emitting component 211. Specifically, please refer to FIG. 15 and in combination with FIG. 16 ,FIG. 16 The light pattern of the LED lighting fixture in the embodiment shown in FIG. 14 The light pattern of the LED lighting fixture in the embodiment shown in

[0203] As FIG. 15 Take the working principle of the right second light emitting component 212 as an example, the sawtooth lens 2211 refracts part of the light emitted by the right second light emitting component 212 to be output at a wider angle, so that the light that would have been projected to the area directly below the first light emitting component 211 (which can also be understood as the middle area of the LED lighting fixture, as shown in FIG. 16 in the range of -10 to 10 degrees) is refracted to the left area of the first light emitting component 211 (for example, FIG. 16 in the range of -15 to -40 degrees), in combination with FIG. 16 shown, the light emitted by the right second light emitting component 212 is mainly distributed in the left area (for example, FIG. 16 in the range of -15 to -40 degrees) and the right area (for example, FIG. 16 in the range of 15 to 40 degrees), similar to the right second light emitting component 212, the light emitted by the left second light emitting component 212 is also mainly distributed in the left and right areas. The light pattern distribution of the left and right second light emitting components 212 in combination with the light pattern distribution of the first light emitting component 211 forms a batwing light pattern.

[0204] It should be understood that, FIGS. 14-16 in the range of -15 to -40 degrees) and the right area (for example, FIG. 16 in the range of 15 to 40 degrees), similar to the right second light emitting component 212, the light emitted by the left second light emitting component 212 is also mainly distributed in the left and right areas. The light pattern distribution of the left and right second light emitting components 212 in combination with the light pattern distribution of the first light emitting component 211 forms a batwing light pattern.

[0205] In an embodiment, please refer to FIG. 17 , FIG. 17The diagram shows a serrated lens structure in one embodiment of this application. As shown, the serrated lens 2211 includes a base surface 22111 and a plurality (or at least one) of serrations 22112. The base surface 22111 has a certain thickness d, which can be set from 0.5 mm to 2 mm (for example, approximately 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2 mm). FIGS. 14-15 In the illustrated embodiment, the thickness d is set to 1 mm. The serrations 22112 can be 6 to 9, each occupying a certain width k (e.g., 3 mm) of the base plate, extending upwards from the base surface 22111. Each serration 22112 is configured as a curved lens having a curved surface and a vertical surface. In some examples, the vertical surface height h of each serration 22112 can be set to the same value, for example, 2 mm to 5 mm (e.g., approximately 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm). (mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, 4.6mm, 4.7mm, 4.8mm, 4.9mm, or 5mm). In some examples, the vertical height h of each sawtooth 22112 can also be set to be different. For example, the difference in vertical height between two adjacent sawtooth 22112 is equal, and this height difference can be set to approximately 0.2mm to 0.4mm.

[0206] In embodiments where the sawtooth lens 2211 is disposed in an LED lighting fixture, for example, FIGS. 14-15 As shown, the curved surfaces of each sawtooth 22112 of the sawtooth lens 2211 face away from the first light-emitting component 211. In other embodiments, the curved surfaces of each sawtooth 22112 of the sawtooth lens 2211 are arranged facing closer to the first light-emitting component 211; please refer to [reference needed]. FIG. 18 and FIG. 19 , FIG. 18 The diagram shown is a partial structural schematic of the sawtooth lens and the second light-emitting unit in one embodiment of this application. FIG. 19 This application is displayed as being in FIG. 18The light pattern diagram of the LED lighting fixture in the illustrated embodiment is shown in the figure. The curved surfaces of the sawtooth lens 22112 are arranged towards the direction close to the first light-emitting component 211. Due to the refraction of some light emitted from the second light-emitting component 212 on the right side by the sawtooth lens 2211, although light that might have been projected onto the area directly below the first light-emitting component 211 can be refracted to the right side of the first light-emitting component 211, it also refracts some light to the area directly below the first light-emitting component 211. Combined with… FIG. 19 The light pattern diagram on the right shows that, as... FIG. 18 Under the action of the sawtooth lenses 2211 arranged as shown, the light emitted by the second light-emitting component 212 is distributed on the left and right sides and directly below the first light-emitting component 211. That is, the second light-emitting component 212 not only contributes to the light intensity of the peripheral area of ​​the LED lighting fixture, but also contributes to the light intensity of the central area of ​​the LED lighting fixture. The second light-emitting component 212 on the left is similar to the second light-emitting component 212 on the right, and also contributes to the light intensity of the central area of ​​the LED lighting fixture. The light pattern distribution of the second light-emitting components 212 on the left and right sides, combined with the light pattern distribution of the first light-emitting component 211, forms a distribution as shown in the diagram. FIG. 19 The light pattern diagrams corresponding to the left, center, and right light outputs shown are, as can be seen, non-ideal batwing light patterns, and do not achieve the uniformity required by the sawtooth lens 2211. FIG. 14 and FIG. 15 The effect of the arrangement shown.

[0207] It should be understood that, FIG. 18 and FIG. 19 Taking the second light-emitting components 212 on the left and right sides as an example, the working principle of the second light-emitting components 212 on the front and rear sides is similar to that on the left and right sides. After being acted upon by their respective sawtooth lenses 2211, the light emitted by the second light-emitting components 212 on the front and rear sides will be concentrated on the front and rear middle sides. Combined with the light pattern distribution of the first light-emitting component 211, it can also be obtained that... FIG. 19 A similar light pattern diagram. Similarly, after the second light-emitting components 212 on the front, back, left, and right sides are acted upon by their respective sawtooth lenses 2211, the emitted light will be concentrated on the front, back, left, right, and center sides. Combined with the light pattern distribution of the first light-emitting component 211, a similar light pattern diagram can be obtained. FIG. 19 Similar light patterns will not be described in detail here.

[0208] Please see FIG. 20 and FIG. 21 , FIG. 20 The diagram shown is a cross-sectional view of an LED lighting fixture including a beam control component along the X-axis in one embodiment of this application. FIG. 21 This application is displayed as being in FIG. 20A partial enlarged view of part B in the illustrated embodiment shows that the light processing unit 22 includes a beam control component 221, which includes a TIR lens 2212 (also known as a Total Internal Reflection lens). The TIR lens 2212 is disposed on the light-emitting side of the second light-emitting component 212, and the number of sets corresponding to the second light-emitting component 212 can be set. FIG. 18-19 In the illustrated embodiment, there are four sets of TIR lenses 2212 corresponding to the number of second light-emitting components 212. The TIR lenses 2212 are arranged parallel to each of the second light-emitting components 212 (i.e., the TIR lenses 2212 are parallel to the sidewall 112 of the first base) to change the light emission path of the second light-emitting components 212.

[0209] The TIR lens 2212 is used to refract a portion of the light emitted from the second light-emitting component 212, so that some of the light is output at a narrower angle (smaller than the original emission angle). This further distributes the light emitted from the second light-emitting component 212 to the areas on both sides of the first light-emitting component, contributing almost nothing to the area directly below the first light-emitting component 211, or the central area of ​​the LED lighting fixture. For details, please refer to... FIG. 21 and combined FIG. 22 , FIG. 22 This application is displayed as being in FIG. 20 The light pattern diagram of the LED lighting fixture in the illustrated embodiment. FIG. 21 As shown, the TIR lens 2212 refracts part of the light emitted from the second light-emitting component 212 on the right, causing it to be output at a narrower angle. This refracts the light that might have been projected onto the middle area of ​​the LED lighting fixture through its original light path to the right area. FIG. 22 As shown, the light emitted by the second light-emitting component 212 on the right is mainly distributed in the left area of ​​the LED lighting fixture (e.g., FIG. 22 The area between -15 and -20 degrees Celsius and the right side (e.g.) FIG. 20 In the range of 15 to 25 degrees, similarly, the light emitted by the second light-emitting component 212 on the left side is also mainly concentrated on the left and right sides of the LED lighting fixture. The light pattern distribution of the second light-emitting component 212 on the left and right sides is combined with the light pattern distribution of the first light-emitting component 211 to form a bat wing light pattern.

[0210] It should be understood that, FIGS. 20-22 The following explanation uses only the second light-emitting components 212 on the left and right sides as examples. The working principle of the second light-emitting components 212 on the front and rear sides is similar to that on the left and right sides. After being acted upon by their respective TIR lenses 2212, the light emitted by the second light-emitting components 212 on the front and rear sides will be mainly concentrated on the front and rear sides. Combined with the light pattern distribution of the first light-emitting component 211, the following can also be obtained: FIG. 22The bat-wing light pattern is shown. Similarly, the second light emitting components 212 on the front, back, left and right sides are affected by the respective corresponding TIR lenses 2212, and the light emitted is mainly concentrated on the front, back, left and right sides, i.e. the peripheral area of the first light emitting component 211. In combination with the light pattern distribution of the first light emitting component 211, a bat-wing light pattern is obtained. FIG. 22 A similar bat-wing light pattern is obtained, which is not described again here.

[0211] In an embodiment, the overall height of the TIR lens 2212 is set to be about 6mm to 8mm, the diameter of the opening on the side facing the second light emitting component 212 is set to be about 2mm to 6mm, and the diameter of the opening on the side away from the second light emitting component 212 is set to be about 10mm to 12mm. In the embodiment shown in FIG. 20 and 21 In the embodiment shown in the drawings, the height of the TIR lens is set to be about 7.5mm, the diameter of the opening on the side facing the second light emitting component 212 is set to be about 6mm, and the diameter of the opening on the side away from the second light emitting component 212 is set to be about 12mm. Those skilled in the art can select appropriate TIR lenses according to the actual size requirements of the LED lighting lamp.

[0212] Please refer to FIGS. 23-29 , FIG. 23 a perspective structural schematic diagram of the LED lighting lamp in an embodiment of the present application is shown, FIG. 24A a split structural schematic diagram of the LED lighting lamp in an embodiment of the present application is shown, FIG. 25 a perspective structural schematic diagram of the light emitting unit, the light beam control component and the supporting unit cooperating with each other in an embodiment of the present application is shown, FIG. 26 a perspective structural schematic diagram of the LED lighting lamp in an embodiment of the present application is shown, FIG. 25 a partial enlarged view of the base and the optoelectronic module in the embodiment shown in the drawings, FIG. 27 a cross-sectional structural schematic diagram of the LED lighting lamp in an embodiment of the present application is shown, FIG. 28 a cross-sectional structural schematic diagram of the LED lighting lamp in an embodiment of the present application is shown, FIG. 27 a partial enlarged view of part C in the embodiment shown in the drawings, FIG. 29 a perspective structural schematic diagram of the LED lighting lamp in an embodiment of the present application is shown, FIG. 27 a light pattern diagram of the LED lighting lamp in the embodiment shown in the drawings. As shown in the drawings, the light beam control component 221 includes a light reflecting structure 2213, which is arranged on the light emitting side of the second light emitting component 212. The number of groups corresponding to the second light emitting component 212 can be set, and in FIGS. 23-27 In the embodiment shown in the drawings, the light reflecting structure 2213 has 4 groups corresponding to the number of the second light emitting component 212. The light reflecting structure 2213 is used to concentrate the light emitted by the second light emitting component 212, so as to improve the light intensity of the peripheral area of the first light emitting component 211. Specifically, please refer to FIGS. 27-29, the light reflection structure 2213 reflects the light rays emitted by the second light emitting component 212 to achieve light collection of the second light emitting component 212 (e.g., the light emitted by the second light emitting component 212 is collected within the included angle range formed by the light reflection structure 2213, as shown by the dashed arrows in FIG. 28 Fig. 6), thereby further enhancing the light intensity of the peripheral region of the first light emitting component 211, so that the LED lighting lamp presents a bat-wing light pattern as shown in FIG. 29 Fig. 6.

[0213] Please refer to FIGS. 25-30 , FIG. 30 Fig. 7 shows a perspective view of the light reflection structure and the second light emitting component in an embodiment of the present application. The light reflection structure 2213 includes a first light reflection plate 22131 and a second light reflection plate 22132, which are respectively arranged obliquely to the two sides of the light emission center line L of the second light emitting component 212, so as to FIG. 30 For example, the oblique angles of the first light reflection plate 22131 and the second light reflection plate 22132 relative to the light emission center line L of the second light emitting component 212 are marked as θ. The first light reflection plate 22131 and the second light reflection plate 22132 can be respectively connected to the mounting surface of the second light emitting component 212, such as the first base side wall 112, or can be respectively connected to the second circuit board 2121 (as shown in FIG. 30 Fig. 7), as long as the first light reflection plate 22131 and the second light reflection plate 22132 are respectively located on the two sides of the second light emitting body 2122. The first light reflection plate 22131 and the second light reflection plate 22132 respectively form two reflection surfaces for the light emitted by the second light emitting component 212, so as to reflect the light rays with an emission angle exceeding the included angle formed by the first light reflection plate 22131 and the second light reflection plate 22132, to collect the light emitted by the second light emitting component 212 and enhance the light intensity of the peripheral region of the first light emitting component 211.

[0214] In an embodiment, the oblique angle θ of the first light reflection plate 22131 and the second light reflection plate 22132 relative to the light emission center line L of the second light emitting component 212 can be set to 15 to 25 degrees (e.g., about 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, 20 degrees, 21 degrees, 22 degrees, 23 degrees, 24 degrees, or 25 degrees), that is, the included angle 2θ formed by the light reflection structure 2213 for collecting the light emitted by the second light emitting component 212 can be set to 30 to 50 degrees. Setting the oblique angle θ within this range can make the LED lighting lamp form a better bat-wing light pattern. For example, FIG. 31 as shown in FIG. 31FIG. 1 shows a light distribution pattern of an LED lighting fixture according to an embodiment of the present application, FIG. 31 In (a), the light distribution pattern of the LED lighting fixture is shown with the first tilt angle β set to 45 degrees and the tilt angle θ of the first and second reflectors 22131, 22132 relative to the light emission center line L of the second light emitting component 212 set to 15 degrees. In this case, the light distribution pattern of the LED lighting fixture can also exhibit a good batwing light distribution. If the tilt angle θ is less than 15 degrees, the light emission of the second light emitting component 212 will be excessively concentrated by the reflector structure 2213, making it difficult to form a batwing light distribution. FIG. 31 In (b), the light distribution pattern of the LED lighting fixture is shown with the first tilt angle β set to 45 degrees and the tilt angle θ of the first and second reflectors 22131, 22132 relative to the light emission center line L of the second light emitting component 212 set to 25 degrees. Although FIG. 31 The LED lighting fixture in (b) can still exhibit a batwing light distribution, but the effect of the batwing light distribution is worse than that in (a). FIG. 31 (a). If the tilt angle θ continues to increase to more than 25 degrees, the light emission of the second light emitting component 212 will not be sufficiently concentrated by the reflector structure 2213, and the light intensity contribution of the second light emitting component 212 to the peripheral region of the first light emitting component 211 will be weakened, making it difficult to form a good batwing light distribution.

[0215] It should be understood that FIG. 30 and FIG. 31 It should be understood that the tilt angle θ of the first and second reflectors 22131, 22132 relative to the light emission center line L of the second light emitting component 212 does not necessarily need to be set to the same degree. It is only necessary that the first and second reflectors 22131, 22132 be tilted relative to the light emission center line L of the second light emitting component 212 and that the tilt angle θ be within a range of 15 degrees to 25 degrees.

[0216] It should be understood that FIGS. 14-30 The sawtooth lens, TIR lens, and reflector structure shown are only examples of structures that can be included in the light beam control component. Those skilled in the art can select any suitable component or structure as part of the light beam control component according to requirements, as long as the light beam control component can change the path of the light emitted by the second light emitting component so that the light emitted by the second light emitting component is mainly distributed in the peripheral region of the first light emitting component. The present application does not limit this. Of course, in other embodiments, the light beam control component can also include other components or structures, etc., to change the light emission path of the light emitting unit to achieve a better light emission effect.

[0217] According to any of the foregoing embodiments, it can be known that the light type distribution of any two opposite groups of second light emitting components 212 in combination with the light type distribution of the first light emitting component 211 can improve the illumination uniformity of the LED lighting lamp, so that the user can selectively open or close any two opposite groups or all of the second light emitting components 212 according to the actual lighting needs by the control switch matched with the LED lighting lamp. In this way, the user's needs can be met while saving energy.

[0218] In some embodiments, the light type distribution formed by the LED lighting lamp is related to the first inclination angle β. Under the premise that the first inclination angle β satisfies the requirement that the light intensity distribution of the LED lighting lamp meets the uniformity requirement, the first inclination angle β is positively correlated with the light output angle of the LED lighting lamp, that is, the greater the first inclination angle β, the greater the light output angle of the LED lighting lamp. In the embodiment or example in which the light type distribution of the LED lighting lamp is in the form of a bat-wing light type or a near-bat-wing light type, that is, the greater the first inclination angle β, the wider the bat-wing light type or the near-bat-wing light type. Please refer to FIG. 32 , FIG. 32 The light type diagrams of the LED lighting lamps configured with different first inclination angles in an embodiment of the present application are shown. Taking the LED lighting lamp configured as shown in FIGS. 23-27 as an example, FIG. 32 (a) the light type diagram with the first inclination angle β configured as 30 degrees, FIG. 32 (b) the light type diagram with the first inclination angle β configured as 45 degrees. By comparison, FIG. 32 (a) relative to FIG. 32 (b), the first inclination angle β is smaller, and the corresponding formed angle of the bat-wing light type is also narrower. Similarly, FIG. 32 (b) relative to FIGS. 1-5 (a), the first inclination angle β is larger, and the corresponding formed angle of the bat-wing light type is also wider. Therefore, the person skilled in the art can adaptively configure the first inclination angle β according to the actual application scenario.

[0219] In some embodiments, the uniformity of the light distribution of the LED lighting fixture is further improved by setting the power supply characteristics of the first light emitting assembly and the second light emitting assembly, for example, to make the LED lighting fixture present a better batwing light distribution or a near batwing light distribution. The power supply characteristics refer to the electrical characteristics delivered to the light emitting units. In the embodiments or examples in which the optoelectronic module further comprises a power supply unit connected to an external power source or mains to supply power to the light emitting units, the power supply characteristics refer to the electrical characteristics delivered to the light emitting units by the power supply unit. The power supply characteristics include, but are not limited to, any of the supply voltage, the supply current, the supply frequency, etc. In an embodiment, the power supply characteristics of the second light emitting assembly and the first light emitting assembly are configured in a preset ratio to improve the batwing light distribution of the LED lighting fixture. For example, the supply voltage of the second light emitting assembly and the first light emitting assembly can be configured in a preset ratio to make the LED lighting fixture present a light distribution with a weaker light intensity in the middle region and a stronger light intensity in the peripheral region, i.e., a batwing light distribution. Further, the preset ratio of the supply voltage of the second light emitting assembly and the first light emitting assembly can be configured to be 1.5 to 3 (for example, the ratio can be about 1.5, 2, 2.5, or 3), and more preferably, the preset ratio of the supply voltage of the second light emitting assembly and the first light emitting assembly can be configured to be 2 to 2.5.

[0220] To reduce the glare of the lighting fixture, in some embodiments, the light processing unit 22 further comprises a diffusing member 222 for diffusing the light generated by the light emitting unit 21 when the light emitting unit 21 is working. Further, in some embodiments, the diffusing member 222 can also be formed as the outer cover of the light emitting unit 21 to form a shield and protection for the light emitting unit 21. Of course, in other embodiments, the outer cover of the light emitting unit 22 can exist separately as a part of the light processing unit 21, i.e., the light processing unit 21 can also comprise a plurality of outer covers, such as a first outer cover and a second outer cover, which is not limited in the present application. FIGS. 23-28 FIG. 37 FIGS. 1-5 Of course, in some other embodiments of the present application, the diffusing member 222 can also have other functions, such as the functions of converging and homogenizing, which can also be referred to as light converging elements or others.

[0221] Of course, in some other embodiments of the present application, the diffusing member 222 can also have other functions, such as the functions of converging and homogenizing, which can also be referred to as light converging elements or others.

[0222] In an embodiment, as shown in FIGS. 1-5 ​​As shown, the diffusion member 222 can be provided as two, including a first diffusion member 2221 and a second diffusion member 2222. The first diffusion member 2221 is disposed in the light emitting direction of the first light emitting component 211, for diffusing the light generated by the first light emitting component 211 when in operation. The second diffusion member 2222 is disposed in the light emitting direction of the second light emitting component 212, for diffusing the light generated by the second light emitting component 212 when in operation. In some examples, the light beam control component 221 is disposed on the side of the second diffusion member 2222 facing the second light emitting component 212, for example, by being attached to or by being structurally fitted to the second diffusion member 2222, so that the light emitted by the second light emitting component 212 is first affected by the light beam control component 221 and then diffused by the second diffusion member 2222. In other examples, the light beam control component 221 can also be disposed on the side of the first diffusion member 2221 facing the first light emitting component 211, which is not limited in the present application. It should be understood that the diffusion member 222 is provided as two only as an example. In embodiments in which the light emitting unit 21 includes more light emitting components, the diffusion member 222 can also be provided as more than two, or at least one diffusion member 222, each of which respectively performs light diffusion and / or shielding protection on the corresponding light emitting component, which is not limited in the present application.

[0223] In an embodiment, the first diffusion member 2221 and / or the second diffusion member 2222 can be made of PC material, to have light diffusion function by its own material properties. For example, the first diffusion member 2221 and / or the second diffusion member 2222 can be provided as a milky white PC cover. In other embodiments, the first diffusion member 2221 and / or the second diffusion member 2222 can also be made of transparent material, such as glass or plastic (e.g., acrylic plate), and a diffusion layer can be provided on the surface thereof, so as to have light diffusion function. For example, FIGS. 1-5 As shown, in a specific example, the first diffusion member 2221 can be provided as a cover structure in the shape of an inverted trapezoid, and the second diffusion member 2222 can be provided as a ring-shaped cover structure conforming to the outer edge of the first diffusion member 2221. When the first diffusion member 2221 and the second diffusion member 2222 are configured on the support unit 1, they are adapted to each other to enclose the light emitting surface of the light emitting unit 21. The side of the second diffusion member 2222 facing the second light emitting component 212 can be provided with a mounting structure for configuring the light beam control component 221. It should be understood that, FIGS. 1-5 The first diffusion member 2221 and the second diffusion member 2222 shown are only examples, and their structures and shapes can be adaptively adjusted according to aesthetic requirements, as well as the structures and shapes of the specific support unit 1 and the light emitting unit 21, which are not limited in the present application.

[0224] In some embodiments, the first diffusion member 2221 can also be formed as an outer cover of the first light emitting component 211 to shield and protect the first light emitting component 211, and the second diffusion member 2222 can also be formed as an outer cover of the second light emitting component 212 to shield and protect the second light emitting component 212.

Here, the first diffusion member 2221 can also be referred to as a first outer cover, and the second diffusion member 2222 can also be referred to as a second outer cover. For example, in the embodiment shown in FIG. 2A, the first diffusion member 2221 and the second diffusion member 2222 can be formed as outer covers of the first light emitting component 211 and the second light emitting component 212, respectively, to shield and protect the first light emitting component 211 and the second light emitting component 212.

For example, in the embodiment shown in FIG. 2A, the first diffusion member 2221 and the second diffusion member 2222 can be formed as outer covers of the first light emitting component 211 and the second light emitting component 212, respectively, to shield and protect the first light emitting component 211 and the second light emitting component 212. FIGS. 23-28 In some embodiments, the first diffusion member 2221 can also be formed as an outer cover of the first light emitting component 211 to shield and protect the first light emitting component 211, and the second diffusion member 2222 can also be formed as an outer cover of the second light emitting component 212 to shield and protect the second light emitting component 212. Here, the first diffusion member 2221 can also be referred to as a first outer cover, and the second diffusion member 2222 can also be referred to as a second outer cover. For example, in the embodiment shown in FIG. 2A, the first diffusion member 2221 and the second diffusion member 2222 can be formed as outer covers of the first light emitting component 211 and the second light emitting component 212, respectively, to shield and protect the first light emitting component 211 and the second light emitting component 212.

[0227] FIGS. 23-28 FIGS. 1-5 FIGS. 23-28 ​ ​​​​​​​The relationship between the diffuser 222 shown and other parts of the LED lighting fixture is only illustrative and does not imply that the diffuser 222 shown must correspond to the structure of the LED lighting fixture shown in the figure. For example, Figures 23-28 The third diffuser 2223 used can be replaced with Figures 1-5 The first diffuser 2221 and the second diffuser 2222 in the middle, Figures 1-5 The first diffuser 2221 and the second diffuser 2222 used can also be replaced with Figures 23-28 The third diffusion element 2223 in the middle.

[0228] To prevent users from observing the LED beads of the light-emitting unit through the outer casing or diffuser, in one embodiment, for example, in... Figures 5-7 ,as well as Figures 24A-26 In the embodiment shown, the first light-emitting component 211 is configured in four groups, with each group containing 24 light-emitting elements. The furthest distance between the outer casing of the first light-emitting component 211 and the side facing it is 12cm to 20cm (e.g., approximately 12cm, 13cm, 14cm, 15cm, 16cm, 17cm, 18cm, 19cm, or 20cm), preferably 16cm. For example, in... Figure 5 In the example shown where the outer casing of the first light-emitting component 211 is configured as a first diffuser 2221, the distance between the inverted trapezoidal base plate of the first diffuser 2221 and the first light-emitting component 211 is set to 12cm to 20cm. For example, in... Figure 24A In the example shown where the outer casing of the first light-emitting component 211 is configured as a third diffuser 2223, the furthest distance between the third diffuser 2223 and the first light-emitting component 211 is set to 12cm to 20cm. It should be noted that 12cm to 20cm is only a reference range. This distance is related to the number and distribution density of the first light-emitting components 211, the number and distribution density of light-emitting elements in each group of first light-emitting components 211, etc. Those skilled in the art can select an appropriate distance based on actual design principles, guided by the principles of this application.

[0229] In embodiments where the light-emitting unit 21 includes a first light-emitting component 211, since the emission angle of the first light-emitting component 211 is typically approximately 120 degrees, the illumination of the first light-emitting component 211 will be uneven, resulting in dark areas on the support unit 1 used to support / support the first light-emitting component 211. For example... Figure 6 As shown, its light-emitting unit 21 includes a first light-emitting component 211, which is disposed on the base 11 of the support unit 1. Please refer to the attached document for further details. Figure 33 , Figure 33 This application is displayed as being in Figure 6The light emission diagram of the first light-emitting component 211 in the embodiment shown is shown in the figure. Since the light emission angle of the first light-emitting component 211 is about 120 degrees, the light emitted by the first light-emitting component 211 cannot illuminate the back plate 12 located around the base 11; or, it can only illuminate a small part of the back plate 12. Therefore, a relatively dark area will be formed on the weak light area of ​​the support unit 1.

[0230] It should be noted that the dark area formed on the support unit 1 is due to the limited emission angle of the first light-emitting component. In some embodiments, even if the support unit 1 adopts other structures, a dark area will still be formed on the support unit 1 due to the influence of the emission angle of the first light-emitting component 211. For example Figure 34 and Figure 35 As shown, Figure 34 The diagram shows a three-dimensional structural schematic of the first light-emitting component 211 and the support unit 1 in one embodiment of this application. Figure 35 This application is displayed as follows: Figure 34 The schematic diagram of the light emission of the first light-emitting component 211 in the illustrated embodiment shows that, in this embodiment, the base 11 of the support unit 1 is configured as a planar structure, and the back plate 12 extends outward from the base 11. Furthermore, to improve light emission uniformity, the back plate 12 is configured as a curved surface, that is, an arcuate surface formed by extending outward from the base 11. Of course, depending on the structure and form adopted by the support unit 1, the base 11 and back plate 12 can also be named in other ways, for example, in... Figure 34 In the illustrated embodiment, the base 11 can also be referred to as the first part / first region of the support unit 1, and the back plate 12 can also be referred to as the second part / second region of the support unit 1; this application does not impose any limitations on this. For example... Figure 34 In the structure of the support unit 1 used, such as Figure 35 As shown, since the first light-emitting component 211 is disposed on the base 11 and the light-emitting angle is 120 degrees, almost no light is irradiated on the curved surface formed by the back plate 12, forming a dark area.

[0231] In view of this, in order to solve the problem of dark areas being formed on the support unit 1 due to the limited emission angle of the first light-emitting component 211, in some embodiments, for example... Figures 36-39 In addition to the first light-emitting component 211, the light-emitting unit 21 may further include a third light-emitting component 213. The purpose is to design the light emission direction of the third light-emitting component 213 to form light in the area outside the light emission angle of the first light-emitting component 211, thereby increasing the light uniformity on the surface of the support unit 1 and avoiding the aforementioned dark areas.

[0232] It should be noted that in other embodiments, the light emitting unit can further include other light emitting components in addition to the first light emitting component and the third light emitting component, for example, the second light emitting component described in any of the foregoing embodiments, that is, the light emitting unit can include the first light emitting component, the second light emitting component, and the third light emitting component, that is, the light emitting unit includes at least one of the first light emitting component, the second light emitting component, and the third light emitting component, or the light emitting unit includes at least two of the first light emitting component, the second light emitting component, and the third light emitting component, as long as the third light emitting component can form light rays projected onto the support unit, and other light emitting components included in the light emitting unit are not limited.

[0233] In an embodiment, referring to Figures 36-39 , Figure 36 a perspective structural schematic diagram of an LED lighting lamp according to the present application in an embodiment is shown, Figure 37 a perspective structural schematic diagram of an LED lighting lamp according to the present application in an embodiment is shown, Figure 36 a perspective structural schematic diagram of an LED lighting lamp according to the present application in an embodiment is shown, Figure 38 a perspective structural schematic diagram of an LED lighting lamp according to the present application in an embodiment is shown, Figure 39 a perspective structural schematic diagram of an LED lighting lamp according to the present application in an embodiment is shown, Figure 36 a light emitting schematic diagram of the first light emitting component 211 and the third light emitting component 213 in the embodiment shown in the present application is shown, as shown in the figure, the light emitting unit 21 includes the first light emitting component 211 and the third light emitting component 213. The first light emitting component 211 is arranged on the base 11, and its beam center line is perpendicular to the base 11, and the third light emitting component 213 is located in the accommodating space formed by the support unit 1, and its beam center line forms a certain angle with the beam center line of the first light emitting component 211, and is directed towards the back plate 12 of the support unit 1, that is, the light emitting direction of the third light emitting component 213 is directed towards the side surface of the lamp, further, the beam center line of the third light emitting component 213 is perpendicular to the beam center line of the first light emitting component 211, and is projected on the back plate 12 of the support unit 1. In the present embodiment, the light emitting direction is taken as the reference datum according to the beam center line of the light emitting component.

[0234] In order to fix the third light emitting component 213, the support unit 1 further includes a support structure 14, which is arranged vertically (also referred to as vertically) on the base 11 of the support unit 1, and is used to arrange the third light emitting component 213, that is, the third light emitting component 213 is arranged on the support structure 14.

[0235] As Figures 38-40 shown, Figure 40The diagram shows a structural schematic of the cooperation between the third light-emitting component and the support structure in one embodiment of this application. The support structure 14 can be configured as a support plate, which is vertically fixed on the base 11. The support plate has a first mounting surface 141 and a second mounting surface 142 facing two opposite directions of the support unit 1, that is, the first mounting surface 141 and the second mounting surface 142 are two opposite surfaces of the support structure 14. Correspondingly, the third light-emitting component 213 is configured as at least two sets facing two opposite directions of the support unit 1, that is, at least one set of the third light-emitting component 213 is provided on the first mounting surface 141 and at least one set of the third light-emitting component 213 is provided on the second mounting surface 142. The support structure 14 can be fixed to the base 11, for example, by means of screws and nuts, or by means of adhesive, heat fusion or welding, or by means of means of engaging with the base 11, such as by means of clips or hooks. In order to adapt to the support structure 14, the base 11 can be provided with a structure that matches the support structure 14 to facilitate the installation of the support structure 14. This application does not limit the specific structure.

[0236] The support structure 14 can be set in the middle area of ​​the base 11, and multiple sets of first light-emitting components 211 are symmetrically distributed on both sides of the support structure 14.

[0237] As mentioned earlier, the third light-emitting component 213 is configured with at least two groups. "At least two groups" can be understood as two or more groups. For example, the third light-emitting component 213 can be configured with 2, 3, 4, 5, or 6 groups, etc., as long as two of these groups face two opposite directions from the support unit 1. Figure 40 The illustrated embodiment is used as an example, and in conjunction with Figure 39 ,exist Figure 39 In the embodiment shown, the third light-emitting component 213 is configured as 6 groups symmetrically distributed on the first mounting surface 141 and the second mounting surface 142. That is, 3 groups of third light-emitting components 213 are arranged in parallel on the first mounting surface 141, and 3 groups of third light-emitting components 213 are also arranged on the second mounting surface 142 at the corresponding positions of the first mounting surface 141. In this way, it can further ensure that the entire front of the support unit 1 emits light uniformly.

[0238] The third light-emitting component 213 may include a third circuit board 2131 and a third light-emitting element 2132. The third light-emitting element 2132 may be an LED bead or other type of LED light-emitting unit. The third circuit board 2131 is attached (e.g., directly attached or attached through an intermediate medium) to the base 11, and multiple third light-emitting elements 2132 may be configured, with the multiple third light-emitting elements 2132 evenly distributed on the third circuit board 2131.

[0239] Considering that the emitted light from the first light-emitting component 211 will be projected onto the edge area of ​​the support unit 1, for example, the area of ​​the back plate 12 away from the base 11, multiple sets of third light-emitting components 213 continuing to project onto this area would cause the edge area of ​​the support unit 1 to be too bright. Therefore, in some embodiments, the number of third light-emitting elements 2132 of the third light-emitting component 213 is related to the distance between the third light-emitting component 213 and the base 11. When the distance between the third light-emitting component 213 and the base 11 of the support unit 1 exceeds a preset value, the number of third light-emitting elements 2132 is reduced. Figure 40 As shown in the example, on the first mounting surface 141, the two sets of third light-emitting components 213 closer to the base 11 include 48 third light-emitting elements 2132, and the one set of third light-emitting components 213 farther from the base 11 includes 26 third light-emitting elements 2132.

[0240] Please see Figures 41-43 , Figure 41 This application is displayed as being in Figure 36 The light pattern diagram of the LED lighting fixture in the illustrated embodiment is shown. Figure 42 This application is displayed as being in Figure 36 The illuminance diagram of the illuminated surface at 2.5m from the LED lighting fixture in the illustrated embodiment. Figure 43 This application is displayed as being in Figure 36 The illuminance diagrams for different areas within the LED lighting fixture in the illustrated embodiment are shown below. Figures 41-43 The effect of the third light-emitting group of 213 pieces in improving the uniformity of light output and avoiding dark areas is explained.

[0241] like Figure 41 As shown, adding a third light-emitting component 213 to the first light-emitting component 211 in an LED lighting fixture will not adversely affect the light pattern of the LED lighting fixture, but it will cause the LED lighting fixture to exhibit a Lambertian or near-Lambertian light pattern, further... Figure 42 The diagram illustrates the illuminance at a distance of 2.5m from the LED lighting fixture, which conforms to the illuminance characteristics of a Lambertian or near-Lambertian light pattern, providing uniform and soft illumination. Figure 43As shown, several areas of the back panel of the LED lighting fixture are selected and labeled as E, F, G, and H, respectively, and their corresponding illuminance diagrams are labeled as (e), (f), (g), and (h), respectively. The area corresponding to the base of the LED lighting fixture is selected and labeled as I, and its corresponding illuminance diagram is labeled as (i). By comparing area I with areas E, F, G, and H, the illuminance of the LED lighting fixture conforms to the characteristics of a Lambertian or near-Lambertian light pattern, that is, the illuminance of area I is the strongest, while the illuminance of the side areas, namely areas E, F, G, and H, is relatively weak. From the comparison between areas E, F, G, and H, the illuminance of each area in the side areas is within a roughly the same range, which means that the side areas of the LED lighting fixture (such as the back panel) are generally uniform, and there are no dark areas in areas E, F, G, and H.

[0242] To reduce glare from the light fixtures, as previously described, the light processing unit 22 includes a diffuser 222, and further, in such a way... Figure 37 In the illustrated embodiment, the diffuser 222 includes a fourth diffuser 2224, which is disposed in the light emission direction of the first light-emitting component 211 and the third light-emitting component 213, and is used to diffuse the light generated by the first light-emitting component 211 and the third light-emitting component 213 during operation. The materials and functions of the fourth diffuser 2224 are the same as those of the third light-emitting component 213. Figures 1-5 ,as well as Figures 23-28 The diffusion components used are similar; please refer to the aforementioned [reference needed]. Figures 1-5 ,as well as Figures 23-28 The description of the diffuser is omitted here.

[0243] Please continue reading. Figure 39 ,like Figure 39 As shown, since the emission angle of the third light-emitting component 213 is also 120 degrees, the light intensity of the central area of ​​the lamp is contributed only by the light from the first light-emitting component 211. That is, the third light-emitting component 213 cannot illuminate the area from -30 degrees to 30 degrees with the vertical direction of the support structure 14 as the center line. However, the light intensity of the area from -30 degrees to -60 degrees and from 30 degrees to 60 degrees with the vertical direction of the support structure 14 as the center line is contributed by both the first light-emitting component 211 and the third light-emitting component 213. As a result, the brightness contrast of the LED lighting fixture is too high, causing glare to the human eye.

[0244] Therefore, in one embodiment, as Figures 36-45 ,in, Figure 44 This application is displayed as being in Figure 37 A schematic diagram of the split structure of the light processing unit in the embodiment shown. Figure 45 This application is displayed as being in Figure 36The cross-sectional structure schematic diagram of the LED lighting lamp in the embodiment shown, the light processing unit 22 further comprises a light shielding assembly 223, which is fixedly connected with the diffusion member 222. The light shielding assembly 223 comprises a light shielding part 2231, which is arranged in the vertical direction of the support structure 14 and close to the side of the support structure 14 away from the support unit 1. The shielding part 2231 extends along the length direction of the support structure 14, or also can be called, along the length direction of the third light emitting assembly 213, so as to form a shield for the area (such as the area of -30 degrees to 30 degrees with the vertical direction of the support structure 14 as the center line) not projected by the third light emitting assembly 213, so as to reduce the discomfort of the human eye.

[0245] In an embodiment, the light shielding part 2231 is arranged outside the fourth diffusion member 2224 and adheres to the fourth diffusion member 2224. The light shielding part 2231 can be arranged as a metal strip shape adapted to the shape of the fourth diffusion member 2224. In order to facilitate the arrangement of the light shielding part 2231, the light shielding assembly 223 further comprises a frame part 2232, which can be formed by continuing the extension of the light shielding part 2231. The frame part 2232 can fix the light shielding part 2231 outside the fourth diffusion member 2224 and also can be used to position the fourth diffusion member 2224 on the support unit 1. Therefore, the fourth diffusion member 2224 can be arranged to have an outer surface shape adapted to the shape of the light shielding part 2231 and the frame part 2232, so as to facilitate the fixation of the fourth diffusion member 2224 without affecting the appearance of the lamp.

[0246] The frame part 2232 and the light shielding part 2231 can be integrally formed as a metal frame structure, can be arranged in a detachable connection mode, or a fixed mode connection, and also can be arranged that the frame part 2232 wraps the light shielding part 2231, which is not limited in the present application.

[0247] In other embodiments, the light shielding part 2231 can also be arranged inside the fourth diffusion member 2224, and the fourth diffusion member 2224 is provided with a corresponding accommodating structure to facilitate the arrangement of the light shielding part 2231.

[0248] In some other embodiments of the present application, the number of support structures 14 can be greater than zero, that is, at least one. The support structures 14 can be arranged in multiple parallel lines to better solve the dark area problem.

[0249] In some other embodiments of this application, the number of support structures 14 can be greater than zero, that is, at least one. The support structures 14 can be arranged in a staggered manner with a certain included angle, such as 90° or 45°, for example, arranged in a "+" structure, or appearing in an "I" shaped structure in some lamps with large aspect ratio differences, so that the light-emitting components 213 located on the support structure 14 can be projected to all corners of the LED lighting fixture, greatly reducing the dark area.

[0250] In some embodiments, the photoelectric module 2 may further include a power supply unit (not shown), which is disposed on the support unit 1 and electrically connected to the light-emitting unit 21 for connecting to an external power source or mains power. Please refer to... Figure 2 , Figure 3 ,as well as Figure 36 To protect the power supply unit, the support unit 1 further includes a power module 3, which includes a power box for providing installation space for the power module. Figure 2 , Figure 3 ,as well as Figure 36 In the example shown, the power module 3 is disposed on the back of the support unit 1, and the power unit is disposed inside the power box. In other examples, the power box may not be provided, and the power unit (a separate power unit can also be referred to as a power module) may be directly disposed on the front or back of the support unit 1. The power unit may include several electronic components and wiring components. The electronic components may be disposed on the circuit board corresponding to the power unit, or some of them may be disposed on the circuit board corresponding to the light-emitting unit 21, so as to share the same circuit board with the light-emitting unit 21.

[0251] See Figures 46-53 As shown, this is another embodiment of an LED lighting fixture in this application. This fixture can emit light at multiple angles and can be referred to as a full-emission LED lighting fixture. For example, it can be a suspended linear fixture or a fixture fixed to the ceiling or suspended ceiling. The spatial position of this LED lighting fixture is located as follows: Figure 46 or Figure 50 In the Cartesian coordinate system shown, the LED lighting fixture includes: a support unit 1, a photoelectric module 2, and a diffuser 222 (which can also be called a light processing unit). The plane where the support unit 1 is located is parallel to the xy plane, the photoelectric module 2 emits light approximately along the z-axis, and the diffuser 222 itself is also approximately parallel to the xy plane.

[0252] See Figures 46-47AAs shown, the part structure of the supporting unit 1 from the edge to the center is arched to one side (for example, along the positive direction of the z-axis) to form a back plate 12. Specifically, the back plate 12 connects the open end of the supporting unit 1 as the back plate bottom, and the back plate 12 is away from the closed end of the supporting unit 1 as the back plate top. The inner wall connecting the back plate bottom and the back plate top can be referred to as a side wall. As preferred, the supporting unit 1 and the back plate 12 can be stamped or injection molded from a metal material or a plastic material to improve production efficiency and ensure the structural strength of the lamp housing. More preferably, the supporting unit 1 and the back plate 12 can be made of an aluminum alloy material to reduce the overall weight of the LED lighting lamp. At the same time, since the supporting unit 1 and the back plate 12 of the LED lighting lamp are made of an aluminum alloy material, they have good heat conduction performance and can fully transfer the heat generated by the optoelectronic module 2 to the atmospheric environment, thereby improving the heat dissipation performance of the LED lighting lamp and ensuring that the LED lighting lamp is always in a temperature-optimal working environment. Generally speaking, the service life of the LED lighting lamp can be effectively guaranteed under the condition that the ambient temperature does not exceed 35 degrees. In some embodiments, the back plate 12 and the supporting unit 1 are integrally formed. Of course, in some other embodiments, the back plate 12 and the supporting unit 1 can be independently formed and then assembled.

[0253] The specific shape of the supporting unit 1 is not limited and can be a strip shape, a circular shape, a rectangular shape, or other special shapes. In this embodiment, the shape of the supporting unit 1 is a rectangular structure as a whole. The edge of the supporting unit 1 can be designed with an upwardly turned folded edge. The rounded edge is formed by folding without additional processing, which forms an edge with high safety for use and installation. At the same time, the folded edge strengthens the structural strength of the edge of the supporting unit 1 to prevent deformation. Further, the folded edge can enhance the aesthetics of the supporting unit 1. The right angle of the supporting unit 1 is designed with an arc chamfer to avoid sharp corners to improve safety during transportation and installation.

[0254] Referring to Figures 47A-49B and Figures 51A-53 As shown, the optoelectronic module 2 is arranged in the back plate 12. As preferred, the optoelectronic module 2 is connected to the back plate 12 in a detachable manner. For example, the optoelectronic module 2 and the back plate 12 are connected by a buckle / engagement structure, or the optoelectronic module 2 is connected to the back plate top of the back plate 12 by screws, or the optoelectronic module 2 is magnetically attracted to the inside of the back plate 12. The detachable connection facilitates the replacement of the optoelectronic module 2 or the components on the optoelectronic module 2 of the LED lighting lamp with a fault. Of course, the optoelectronic module 2 can also be fixed in the back plate top of the back plate 12, but it cannot be easily detached.

[0255] The light emitted by the photoelectric module 2 is at least partially directed to and projected to the periphery of the inner wall (also referred to as the side wall) of the backboard 12. Specifically, the photoelectric module 2 includes multiple rows of light strips (or LED lamp beads, LED arrays, i.e., multiple light emitting elements), and the multiple rows of light strips have different light emitting directions and angles, i.e., light emitting at least at two angles. The light strips can be arranged along the x-axis direction and / or the y-axis direction. Some of the light strips are directed to the slot of the backboard 12 and / or the top region of the backboard to emit light, and some of the light strips can be directed to the side wall of the backboard 12 to emit light. The dark area around the backboard 12 is brightened by dispersing the light, and the light around the center region of the backboard 12 tends to be uniform, thereby solving the problem of uneven brightness of the LED lighting lamp, and effectively improving the light emitting effect. The diffusion member 222 is arranged on the side of the photoelectric module 2 away from the top of the backboard 12 of the backboard. The diffusion member 222 can cover at least part of the photoelectric module 2, i.e., the projection of the diffusion member 222 in the z-axis direction can completely cover or at least partially cover the photoelectric module 2. As a preferred embodiment, the diffusion member 222 completely covers the photoelectric module 2, so as to diffuse most of the light emitted by the photoelectric module 2, making the light emitted by the LED lighting lamp more uniform and soft, and avoiding the problem of glare and dazzling caused by the light emitted too concentrated in the center region of the backboard 12. The photoelectric module 2 includes at least two light emitting directions, and at least two light strips (or LED lamp beads, LED arrays, i.e., at least two light emitting elements) are arranged on at least two mounting surfaces. In another aspect, the optical axes or extensions of the optical axes of the at least two light strips (or LED lamp beads, LED arrays) intersect. It should be noted that the at least two light strips (or LED lamp beads, LED arrays) can also be arranged on the upper and lower surfaces of the same mounting component.

[0256] The cover surface of the diffusion member 222 is slightly arched in the z-axis direction to form a convex structure, i.e., an arc-shaped structure, so as to better diffuse the light. The diffusion member 222 can be a light-transmitting material, for example, glass, acrylic, etc. A diffusion coating or diffusion film can be arranged on the surface of the diffusion member 222, so as to diffuse the light. Alternatively, the diffusion member 222 can be partially transparent. For example, the diffusion member 222 can be a milky white PC cover with a certain haze. Due to the material properties, the PC cover also has a light diffusion function, so as to make the light more soft.

[0257] Referring to Figure 47A , Figure 47B and Figure 51AAs shown, in an embodiment, mounting holes 15 are provided on the back plate top of back plate 12, which can be located in the central region and / or edge region of the back plate top of back plate 12, and the number and shape of mounting holes 15 are not limited. Mounting holes 15 are matched with connecting members such as bolts, hangers, chains, etc. to suspend or mount the shell of the LED lighting fixture (i.e. support unit 1 and back plate 12) to the ceiling, thereby achieving the installation of the LED lighting fixture.

[0258] Of course, mounting holes 15 can also be provided on the back plate bottom, for example, on the four corners of the back plate bottom, and the LED lighting fixture is embedded in the installation surface such as the ceiling, and the back plate bottom is substantially parallel to the installation surface such as the ceiling, the height of back plate 12 is hidden inside the ceiling, the bottom plate of the LED lighting fixture and the ceiling surface are smoothly connected, the surface difference between the two is not more than twice the thickness of the edge of the lamp, and the overall surface formed between the installation plane after installation is smooth, and the visual effect is good.

[0259] Further, part of the back plate top of back plate 12 is recessed towards the optoelectronic module 2 to form a reinforcing rib 16, i.e. the back plate top of back plate 12 has different height regions. By designing reinforcing rib 16, the structural strength of part of the back plate top of back plate 12 can be significantly improved, and the problems of warping and deformation during the installation of the LED lighting fixture can be avoided. As an example, reinforcing rib 16 can be a single or multiple straight line structure, or a mesh or divergent structure, and the specific design is not limited. In an embodiment, reinforcing rib 16 is a single straight line structure extending along the y-axis direction, the length of reinforcing rib 16 does not exceed the length of the back plate top of back plate 12, and the number of mounting holes 15 is two, which are respectively arranged at the two ends of reinforcing rib 16 to balance the force on both ends of the LED lighting fixture and improve the stability and reliability after installation. Of course, if back plate 12 itself has sufficient strength, reinforcing rib 16 can not be provided, thereby simplifying the production process.

[0260] Referring to Figure 46 and Figure 50 As shown, in some embodiments, the inner wall of back plate 12 is provided with a reflecting surface, specifically, the reflecting surface is the inner wall surface of the back plate top and the side wall of back plate 12. The reflecting surface can perform secondary distribution on the light emitted from the optoelectronic module 2 in different light emitting directions and at different light emitting angles, so as to improve the light uniformity of light emission and improve the lighting effect. As a preferred embodiment, the reflecting surface is a diffuse reflecting surface, which can be obtained by mechanical processing or chemical treatment. The diffuse reflecting surface can reflect light in all directions to disperse light, thereby reducing glare and local strong light, and at the same time, most regions in the light emitting direction of the LED lighting fixture have light emission, avoiding local dark areas and further improving the light emission effect.

[0261] Referring to Figures 46-49BAs shown, in the first embodiment, the light and electricity module 2 of the LED lighting fixture comprises a first support 210, a first light emitting assembly 211' and a second light emitting assembly 212', wherein the first light emitting assembly and the second light emitting assembly can also be described as part of a light emitting unit.

[0262] Referring to Figures 47A-47C , the first support 210 is arranged in the back plate 12, the first support 210 is in a "Hui" character-shaped structure, as an example, the first support 210 is in a vertical state or close to a vertical state as a whole and is fixed in the back plate 12, the first support 210 comprises two parts of an inner support 2101 and an outer support 2102 (see Figure 47C and Figure 49A ), the inner support 2101 and the outer support 2102 are preferably made of light-tight materials, such as light-tight plastics, aluminum alloys, carbon fibers, etc., to reduce the weight of the LED lighting fixture, and the inner support 2101 and the outer support 2102 both have positions for mounting LED light strips, the inner support 2101 and the outer support 2102 are arranged at a certain interval, can have different angles relative to the back plate 12, the inner support 2101 is surrounded by the outer support 2102, and the two can be a sheet-shaped ring structure ("Hui" character-shaped structure).

[0263] The first light-emitting assembly 211' includes a first light-emitting body 2112' and a first light-emitting body 2112'', wherein the first light-emitting body 2112' is arranged in the back plate 12, preferably at the central region of the top of the back plate, and the number of the first light-emitting body 2112' can be one, two or more, which is selected according to the actual required illumination brightness. As an example, the first light-emitting body 2112' is arranged horizontally at the reinforcing rib 16 of the back plate 12, and the first light-emitting body 2112' emits light in the z-axis direction, towards the central region of the diffuser 222. The first light-emitting body 2112'' is arranged on the inner edge region of the first support 210, i.e. the inner support 2101, i.e. the side of the inner support 2101 facing the first light bar 211. The number of the first light-emitting body 2112'' can be two, four or more, which is adjusted according to the light brightness of the first light-emitting body 2112'. As an example, the number of the first light-emitting body 2112'' is two and symmetrically arranged on both sides of the first light-emitting body 2112', and the first light-emitting body 2112'' can be vertically or obliquely mounted on the inner support 2101. As a preferred example, the inner support 2101 is provided with an inclined mounting surface, which makes the light emitted by the second light bar 222 more from the diffuser 222, i.e. the light emitting angle has a higher degree of coincidence with the diffuser cover. The first light-emitting body 2112'' is obliquely arranged on the mounting surface, and the light emitting direction of the first light-emitting body 2112'' is reversely intersected with the z-axis, so as to emit light towards the edge region of the diffuser 222. Through the cooperation of the first light-emitting body 2112' and the first light-emitting body 2112'', the diffuser 222 of the LED lighting lamp can be uniformly illuminated everywhere, and the light emitting effect is improved.

[0264] The second light-emitting assembly 212' is an LED light bar, which is arranged on the outer edge region of the first support 210, i.e. the outer support 2102. The number of the second light-emitting assembly 212' can be one, two, four or more, and the second light-emitting assembly 212' can also be vertically or obliquely mounted on the outer support 2102 to realize light emission in different directions and at different angles. As an example, the number of the second light-emitting assembly 212' is four and uniformly arranged around the outer support 2102 in a vertical state, and the second light-emitting assembly 212' emits light in the x-axis and y-axis directions, uniformly illuminating the top region and the side wall region of the back plate 12, so that the brightness of all regions of the whole lamp tends to be consistent, thereby improving the appearance and illumination effect of the LED lighting lamp.

[0265] Referring to Figure 49B It is a structure schematic view of the first support 210 in the present application after removing the diffuser 222 and the remaining components. Combined with Figures 46-49AIt can be seen that the inner side of the first support 210 in the vertical state can be referred to as the inner support 2101, and the outer side in the vertical state can be referred to as the outer support 2102. An edge of a certain length extends outward at one end of the inner support 2101 and the outer support 2102 facing the diffusion member 222, which can be horizontal or have a certain angle, and at the same time, the edge can play a certain shading role. For the sake of description, the latter is referred to as the shading eaves 23. The angles of the inner support 2101, the outer support 2102, and the shading eaves 23 can all be specifically designed according to actual needs and are not limited to the examples in the embodiments of the present application. The inner support 2101, the outer support 2102, and the shading eaves 23 can be integrally formed or separately formed and then assembled into one body.

[0266] Overall, the photoelectric module 2 in the full-emitting LED lighting lamp of Embodiment 1 has a simplified structure and a beautiful shape. By establishing light-emitting routes in different directions and at different angles, cooperating with the back plate 12 and the diffusion member 222 for reflection and diffusion, the light-emitting effect of the LED lighting lamp can be effectively improved.

[0267] Referring to Figure 49A As shown in the figure, the angle a between the plane where the first light emitter 2112” is located and the plane where the top of the back plate 12 is located is greater than 90°. As a preferred, the angle a is greater than 90° and less than 150°, which can ensure that the first light emitter 2112” emits light towards the edge region or the central region of the diffusion member 222. In an embodiment, the angle a between the plane where the first light emitter 2112” is located and the plane where the top of the back plate 12 is located is 120°. At this time, the light-emitting direction of the first light emitter 2112” is more inclined to the edge region of the diffusion member 222, which can reduce the overlapping range of light emission with the first light emitter 2112’, disperse the light emitted by the first light assembly 211’, and improve the uniformity of illumination.

[0268] In a preferred embodiment, the first support 210 extends radially around one end away from the top of the back plate 12 to form the shading eaves 23. Specifically, the shading eaves 23 is formed by bending one end of the inner support 2101 of the first support 210 and extending outward in a nearly horizontal state. The shading eaves 23 as a whole has a ring structure (see Figure 47A Figure 49B After the shading eaves 23 is set, the shading eaves 23 can form a shading area with the outer side of the first support 210, and the outer LED light belt is located in the shading area. By setting the shading eaves 23 for shading, the naked eye cannot see the outer LED light belt around a certain range, because the outer LED light belt is hidden in the shading area. Even if the LED lighting lamp is directly viewed, there will be no problem of glare and dazzling.

[0269] In addition to the shading and anti-glare effects, the shading eaves 23 can also be used as an additional mounting surface. The second light-emitting assembly 212' is not limited to being mounted on the outer support 2102, but can also be horizontally or obliquely arranged on the surface of the shading eaves 23 facing the diffusion member 222 or away from the diffusion member 222 (not shown), thereby playing a role of supplementary light to avoid the problem of dark areas caused by excessively dark local areas. Moreover, the shading eaves 23 acting as an additional mounting surface can alleviate the problem of tight installation space on the outer support 2102, thereby facilitating the layout and construction operation of the external light source.

[0270] In a specific embodiment, the diffusion member 222 has an arc-shaped plate structure. This shape of the diffusion member 222 has a beautiful appearance and can more evenly disperse light, thereby reducing the glare effect of the LED lighting lamp. In addition, the profile area of the diffusion member 222 is larger than the profile area of the first support 210, so as to sufficiently shield the optoelectronic module 2. Even in the absence of the shading eaves 23, the larger area of the diffusion member 222 can also play a shielding role to avoid the problem of glare and dazzling caused by direct vision of the external LED light strip. The most distant point of the diffusion member 222 along the light-emitting direction of the LED lighting lamp is smaller than any point on the bottom plate of the base 1, i.e., the diffusion member 222 is completely accommodated in the LED lighting lamp.

[0271] Referring to Figure 49C A brief light-emitting schematic diagram of the LED lighting lamp in the application embodiment is shown, in which the dashed line is a brief schematic of the light. The outer side of the first support 210, i.e., the outer support 2102, emits light to the side wall having a specific curvature and reflection effect. The light emitted by the outer support 2102 is emitted from the outer edge region of the LED lighting lamp after being reflected by at least one layer, so that the outer edge of the LED lighting lamp has a good light-emitting effect. The diffusion member 222 processes the light emitted by the second light strip 222 on the inner support 2101 and the light emitted by the first light strip 221 on the reinforcing rib 16 (for example, uniformization or diffusion, etc.), and then emits the light from the relatively central region of the LED lighting lamp. In this way, the edge and the center of the LED lighting lamp have approximately the same light-emitting effect, and the visual effect has a close brightness, i.e., almost all regions of the LED lighting lamp have a light-emitting effect, for example, more than 90% of the regions.

[0272] In some other embodiments, the region of the LED lighting lamp having a light-emitting effect can also be more than 50%, more than 60%, etc.

[0273] Referring to Figures 50-53 As shown, in the second embodiment, the optoelectronic module 2 of the full-light-emitting LED lighting lamp includes a second support 220, a first light-emitting assembly 211'', a second light-emitting assembly 212'', and a strip-shaped lens 25.

[0274] The second bracket 220 is fixed inside the back plate 12. As an example, the second bracket 220 can be suspended inside the back plate 12. A suspension part 24 can be provided between the second bracket 220 and the top of the back plate 12, and the two parts are connected by the suspension part 24. That is, one end of the suspension part 24 is fixed to the back plate 12, and the other end is fixed to the second bracket 220. As an example, the suspension part 24 can be a hollow tubular structure to reduce weight. At the same time, wiring can be arranged inside it as needed or not. The height of the suspension part 24 determines the position of the second bracket 220. In order to ensure that the upper half of the back plate 12 can be fully illuminated, the distance from the second bracket 220 to the top of the back plate 12 can be greater than the distance from the second bracket 220 to the bottom plate of the back plate 12. The second bracket 220 is roughly in the shape of a "U" and has mounting positions on both its upper and lower sides for mounting the first light-emitting component 211 and the second light-emitting component 212.

[0275] See Figures 51A-51D Both the first light-emitting component 211” and the second light-emitting component 212” are LED light strips. The first light-emitting component 211” is located at the upper end of the second bracket 220. The first light-emitting component 211” emits light approximately along the positive z-axis, illuminating the top of the back plate 12 and the upper half of its sidewalls. The number of first light-emitting components 211” can be two, four, or more. The second light-emitting component 212” is located at the lower end of the second bracket 220. The second light-emitting component 212” emits light approximately along the negative z-axis, illuminating the bottom of the back plate 12 and the lower half of its sidewalls. The number of first light-emitting components 211” can also be two, four, or more. As an example, there can be four first light-emitting components 211" and four second light-emitting components 212", or two first light-emitting components 211" and two second light-emitting components 212", or two first light-emitting components 211" and four second light-emitting components 212". The specific combination of the number of first light-emitting components 211" and second light-emitting components 212" is not limited, as long as it ensures uniform light emission and improves the lighting effect. In one embodiment, there are two first light-emitting components 211" symmetrically arranged on both sides of the upper end of the second bracket 220, and four second light-emitting components 212" are respectively arranged around the lower end of the second bracket 220. This circular arrangement around the four sides of the second bracket 220 makes the light emission more uniform and improves the lighting effect.

[0276] See Figure 51C and Figure 51DThe strip lens 25 and the diffusion member 222 both have cavities for accommodating the LED light strip, and the cavities form airtight spaces with the upper and lower surfaces of the second support 220 to form a protection structure for the LED light strip. In addition, the cavities of the strip lens 25 and the diffusion member 222 are designed to have specific shapes to achieve different light effects, and the total length of the LED light strip is less than the total length of the cavities.

[0277] In addition, the second support 220 can also have a "I" shape (not shown), and the upper and lower surfaces of the second support are also provided with mounting positions. The first light-emitting assembly 211" and the second light-emitting assembly 212" can be arranged in a straight line on the upper and lower sides of the second support 220, and also have a relatively uniform light emission effect. In some other embodiments, the second support 26 can also have other structures, such as a wave shape, a rectangular surface, etc.

[0278] The photoelectric module 2 in the full-lighting LED lighting lamp described above adopts a suspension design, and also has a simplified structure and a beautiful appearance, which can improve the appearance and lighting effect of the LED lighting lamp. In an embodiment of the present application, one end of the suspension part 24 is fixed near the mounting hole 15 and arranged in the support unit 1, i.e., in the direction of light emission of the lamp. The suspension part 24 is fixed by means of screws, glue, buckles / detachable fasteners, etc. The other end is fixed on the surface of the second support 220. The suspension part 24 and the second support 220 can be integrally formed or separately formed and then fixed to each other.

[0279] In another embodiment of the present application, the suspension part 24 can pass through the mounting hole 15 to be fixed, i.e., the suspension part 24 has a large end and a small end. The projection area of the large end along the Z axis is larger than the mounting hole 15, and the projection area of the small end is smaller than the mounting hole 15. When installed, the small end of the suspension part 24 passes through the mounting hole 15, and the large end is clamped on the outside of the bottom plate 1, i.e., in the opposite direction of the light emission direction of the lamp. Under the action of gravity, the suspension part 24 can be fixed without additional fixing (see Figure 53 ).

[0280] As shown in Figures 51A-53 , the upper part of the first light-emitting assembly 211" is provided with a strip lens 25. The strip lens 25 has a strip shape and is used to guide the light emitted by the upper LED light to disperse to both sides, so as to more uniformly illuminate the middle and surrounding areas of the support unit 1.

[0281] Among them, along the length direction of the vertical strip lens 25, that is, the radial direction, the overall cross-section of the strip lens 25 is a semi-circular structure or an arc structure. A light strip cavity 250 is provided inside the strip lens 25. The cross-section of the light strip cavity 250 can be triangular, arc-shaped, or semi-circular parallel to the semi-circular cross-section of the strip lens 25, etc., but not limited to this, and can be set according to actual light output requirements. In this application, the light strip cavity 250 has a smooth surface, but in other embodiments, it can also be an uneven surface, such as a matte surface, a continuous concave-convex surface, a Fresnel lens surface, etc., for meeting different light effects, such as diffuse reflection, etc. Specifically, when the light emitted by the first light-emitting component 211” exits from the light strip cavity 250, refraction will occur. The luminous flux of any first light-emitting component 211” towards the middle of the backplane 12 is less than the luminous flux towards the surrounding area of the support unit 1. However, after the luminous fluxes of the two first light-emitting components 211” towards the middle of the backplane 12 are superimposed, they will tend to be consistent with the luminous flux of any first light-emitting component 211” towards the surrounding area of the backplane 12, so that no dark area will appear in the entire LED lighting fixture, improving the lighting effect. The length of the light strip cavity 250 in the strip lens 25 is more than 80% of the total length of the strip lens 25. The two ends of the strip lens 25 can be integrally formed closed surfaces, or can be split closed surfaces, or the light strip cavity 250 can completely penetrate the strip lens 25.

[0282] The strip lens 25 can also be formed by arranging independent single lenses.

[0283] In a specific embodiment, the light brightness of the second light-emitting component 212” after passing through the diffuser 222 is one-third to one-fifth of the light brightness of the first light-emitting component 211” after passing through the strip lens 25, preferably one-fourth. As an example, the first light-emitting component 211” provides about 80% of the light source upward, and the second light-emitting component 212” provides about 20% of the light source downward. After being reflected by the backplane 12 and then emitting light, the lighting effect can be effectively improved.

[0284] In a specific embodiment, the diffuser 222 has a “hui” - shaped structure and is fixedly connected to the second bracket 220; the second light-emitting component 212” strip is located inside the diffuser 222, and the diffuser 222 disperses and atomizes the light to achieve a better light output effect.

[0285] See Figure 46 and Figure 50 As shown, in a specific embodiment, the diffuser 222 is located inside the backplane 12 or flush with the plane where the notch of the backplane 12 is located to improve the aesthetic appearance of the LED lighting fixture.

[0286] The LED light strip in the above embodiments of this application can also be composed of LED filaments, LED lamp bead arrays, light bulbs, etc., and other forms but not limited to this.

[0287] In another embodiment of the present application, the light source plate of different directions is further arranged to make the light direction of the optoelectronic module more abundant and uniform, further improve the light uniformity, and provide more installation space for installing the light emitting components in the optoelectronic module through the arrangement of the light source plate.

[0288] Next, the LED lighting lamp (hereinafter referred to as LED lighting lamp) proposed in the present application will be described in conjunction with the drawings.

[0289] As shown in Figure 54 and Figure 55 , the LED lighting lamp proposed in the present application includes a supporting unit 1, a diffusion member 222 (or a light processing unit), a power module 3, and an optoelectronic module 2; the lamp is fixed on the mounting surface, such as the indoor ceiling, through the supporting unit 1 to realize indoor lighting; the diffusion member 222 extends along the X axis direction, i.e., the length direction of the lamp, and the two ends are fixedly connected with the supporting unit 1 through the diffusion member end cover 22210; the diffusion member 222 improves the illuminance uniformity of the lamp, and at the same time, the curved surface of the diffusion member 222 is combined with the supporting unit 1 to form a complete surface type light exit surface in the light exit direction of the lamp, i.e., the positive direction of the Z axis, which ensures the visual integrity and enhances the external beauty of the lamp; the power module 3 is used to supply power to the light source; the optoelectronic module 2 is arranged between the supporting unit 1 and the diffusion member 222, and provides a first light emitting component 211” and a second light emitting component 212” to expand the lighting range, wherein the diffusion member 222 covers the optoelectronic module 2, and more specifically, at least partially or completely covers the optoelectronic module 2, or at least partially or completely covers the light emitting component.

[0290] As shown in Figure 55 , the supporting unit 1 specifically includes a base 11, which can be fixed to the mounting surface by screws, buckles, embedding, etc., and the base 11 can be arranged in an arc structure or a square structure according to actual needs.

[0291] As shown in Figure 54 , Figure 55 and Figure 61As shown, in an embodiment, the base 11 is provided in a square structure, and the front and rear ends of the base 11 are connected with upwardly extending side walls, which can also be first base side walls 112'. The base 11 and the first base side walls 112' at the two ends can be provided in an integrated structure, which is integrally formed by a stamping process, and thus the production process is relatively simple, and the structural strength is relatively high. Alternatively, the base 11 and the first base side walls 112' at the two ends can be provided in a split structure, which is convenient to disassemble and facilitates subsequent maintenance and other work by the staff. Meanwhile, the support unit 1 further includes a back plate 12, which is stacked on the base 11. The back plate 12 is provided in an upper-wide and lower-narrow structure. Specifically, the width of the back plate 12 in the front-rear direction at the upper end is D1, the width of the back plate 12 in the front-rear direction at the lower end is D2, and the width of the first base side walls 112' at the two sides of the base 11 in the front-rear direction at the upper end is D3. D1 needs to be greater than or equal to D2, and preferably, D1 is greater than D2. In order to ensure that the back plate 12 can be conveniently placed into the support unit 1, D3 is greater than D2, D3 is slightly greater than or equal to D1, and the height of the base 11 in the up-down direction is greater than the height of the back plate 12, so as to ensure that the upper edges of the base 11 and the back plate 12 can be closely fitted without a gap, and thus light leakage and other phenomena can be avoided. In an embodiment, the back plate 12 can be provided in a square structure or an arc structure with support plates connected to the side edges.

[0292] As shown, Figure 55 The back plate 12 is provided with an upward protrusion 123 at the central axis extending in the length direction, and a containing cavity is formed between the protrusion 123 and the base 11. The power module 3 is arranged inside the protrusion 123 and fixedly connected to the base 11. The base 11 is provided with an opening corresponding to the position of the power module 3, and the wiring board 33 is electrically connected to the external circuit from the opening. By arranging the power module 3 inside the support unit 1, space multiplexing is achieved, which can effectively save space and reduce the overall height of the lamp. At the same time, the power module 3 and the support unit 1 do not need to be packaged separately, which reduces the packaging volume and the cost.

[0293] As shown, Figure 59 The protrusion 123 extends left and right along the length direction of the lamp. As viewed from the cross section, the protrusion 123 is shaped like a trapezoid. The upper end surface of the protrusion 123 is provided as a relatively flat horizontal surface, which facilitates the installation of the photoelectric module 2 to the upper end surface of the protrusion 123. The two side surfaces of the protrusion 123 are provided as inclined surfaces with a certain inclination angle, which can reflect the light emitted by the lateral light source of the photoelectric module 2 to a certain extent, further enhance the light emission at the lateral position of the lamp, reduce the dark area, and avoid excessive concentration of light emission, thereby enhancing the uniformity of illuminance.

[0294] As shown, Figure 62 In another embodiment, the base 11 is provided in an arc structure, and the arc-shaped opening of the base 11 faces upward. The base 11 is upwardly curved to form a certain space, and the power module 3 can be arranged in the space formed between the upwardly curved base 11 and the mounting surface. The power module 3 is arranged outside the support unit 1, and the power module 3 can be arranged without increasing the overall thickness of the lamp.

[0295] The base 11 is provided with an upward protrusion at the center axis extending along the length direction, and the power module 3 can also be arranged in the protrusion and fixed on the mounting surface, so that the power module 3 is built in the supporting unit 1, without increasing the height and volume of the lamp, and the appearance of the lamp is improved. The protrusion has the same effect as the above-mentioned embodiment, and the relatively flat upper surface thereof can be used to fix the light source module, which will not be described herein again.

[0296] As shown in Figure 55 , the power module 3 comprises a power circuit board 31, which is fixed on the supporting unit 1 by screwing, bonding or clamping or other connection methods. The power circuit board 31 is provided with a wiring board 33, which is connected to an external circuit by wires. The side of the wiring board 33 is provided with a first power supply 32, which is electrically connected to the wiring board 33.

[0297] As shown in Figure 55 , Figure 58 , Figure 59 , Figure 60AAs shown, the back plate 12 is provided with a photoelectric module 2, the photoelectric module 2 includes a light source plate 201, a recess 202 is arranged at the central axis of the light source plate 201, the upper end surface of the light source plate 201 is symmetrical on both sides of the recess 202 as the center, the surface of the recess 202 intersects the plane where the upper end surface is located, and the included angle between the two can be adjusted, and in an embodiment of the application, the two are substantially perpendicular; the upper end surface is provided with two groups of first light emitting assemblies 211", symmetrical arrangement can effectively ensure the uniformity of the front light; each group of first light emitting assemblies 211" includes a first circuit board 2111' arranged on the light source plate 201, and a plurality of first light emitting bodies 2112" are arranged on the first circuit board 2111' and extend left and right along the length direction; when the first light emitting body 2112" is powered on, the first light emitting body 2112" emits upward irradiation light, the number of first light emitting bodies 2112" can be adjusted according to the actual required light intensity, and the more the number of first light emitting bodies 2112", the greater the light intensity of the LED lighting lamp in the forward direction. In the embodiment, at least one row of first light emitting bodies 2112" (such as one row or two rows, etc.) are arranged on the first circuit boards 2111' on both sides. That is, the photoelectric module 2 has light emission in at least two directions. The base 11 includes a bottom plate 111 and a first base side wall 112' (or a side wall), which form a containing cavity in combination with the second end cover 4, and the photoelectric module 2, the power module 3 and the back plate 12 are arranged in the containing cavity. The height of the diffusion member 222 is less than or equal to the height of the first base side wall 112' in the positive direction of the Z axis, so as to ensure the overall installation aesthetics of the lamp and prevent the diffusion member 222 from protruding from the supporting unit 1. The back plate 12 further includes a light emitting curved surface 121 and a combination part 122, wherein the light emitting curved surface 121 corresponds to the lateral light emission of the diffusion member 222, and the lateral light emission of the diffusion member 222 is emitted from the light emitting direction after light processing, wherein the light emitting curved surface 121 can have reflection function, transmission function, refraction function, diffusion function, etc., or simultaneously have at least two or more light processing functions, when the lateral light emission of the diffusion member 222 reaches the light emitting curved surface 121, part of the light is directly reflected, part of the light passes through the light emitting curved surface 121 and reaches the supporting unit 1, and is transmitted from the light emitting curved surface 121 after being reflected by the supporting unit 1. The above process can occur once or more, and of course the lateral light emission of the diffusion member 222 can also be completely reflected from the light emitting surface 121 without reaching the supporting unit 1.The back plate 12 further has a bonding portion 122 which is snap-bonded with an end of the first base sidewall 112', i.e. an end in the positive direction of the Z axis, for example, the bonding portion 122 is a bent structure, the end of the first base sidewall 112' has a matching bend, and the fixing can be completed by pressing the bonding portion 122 to the end of the first base sidewall 112'. Of course, in other ways, the bent bonding portion can be fixed by hot pressing, or additional components such as screws, fixing frames, etc.

[0298] As shown in Figure 58 and Figure 59 , the second light-emitting assembly 212" is arranged on the two opposite sides outside the groove 202, and the bottom of the groove 202 is fixed on the protrusion of the back plate 12 by screws (or glue, welding, buckling, etc.), so that there is a certain height difference between the second light-emitting assembly 212" and the back plate 12, effectively expanding the illumination range of the second light-emitting assembly 212", i.e. expanding the light-emitting range of the second light-emitting assembly 212" to a certain extent. The second light-emitting assembly 212" includes a second circuit board 2121' arranged on the outer sidewall of the groove 202, and a plurality of second light-emitting bodies 2122" are arranged on the second circuit board 2121' along the long axis direction. When the second light-emitting body 2122" is powered, the second light-emitting body 2122" emits light for lateral illumination. The number of second light-emitting bodies 2122" can be adjusted according to the actual required light intensity. The more the number of second light-emitting bodies 2122", the greater the light intensity of the lamp body in the lateral direction. In the present embodiment, one row of second light-emitting bodies 2122" is arranged on each of the two second circuit boards 2121'.

[0299] In some other embodiments of the present application, the lamp beads can also be arranged on the lower surface of the end surface of the light source plate 201, the inclined surface of the protrusion 123, etc. That is, the light emission of the optoelectronic module 2 can be realized through multiple lamp beads arranged at different positions, so that the light emission angle covers a range of 180° along the light emission direction with the plane where the bottom plate 111 is located as the reference,

[0300] Referring to Figure 60A , in combination with Figure 60B and Figure 60C , it can be seen that the light source plate 201, i.e. the light source plate 201 has mounting surfaces with different angles for mounting light-emitting bodies, and the light-emitting bodies with different angles emit light together to form the light emission of the LED lighting lamp. Compared with traditional LED lighting lamps, the light emission angle is larger and the light emission is softer. With the bottom plate 111 as the reference plane, the light emission angle of the LED lighting lamp can be 180°, i.e. the light emission can illuminate each corner of the LED lighting lamp along the light emission direction, avoiding dark areas of the LED lighting lamp.

[0301] Referring to Figure 60B, the light emitting unit 21 is provided with a plurality of light emitters in different directions, so that the light emitting range of the light emitting unit 21 in any plane can reach a 180° sector range with the light emitting unit 21 as the center, as shown in the range a, that is, in the three-dimensional space, it is a hemispherical range with the light emitting unit 21 as the center, see Figure 60D .

[0302] Referring to Figure 60C , that is, the light emitting unit 21 is provided with a plurality of light emitters in different directions, so that the light emitting angle of the light emitting unit 21 along the perpendicular line of the light emitting unit 21 to both sides b1 and b2 can reach the maximum angle 90° defined by the perpendicular line and the bottom plate 111, thereby avoiding the appearance of dark area in the light emitting direction of the LED lighting lamp.

[0303] As Figure 54 , Figure 55 , Figure 64A , the upper part of the optoelectronic module 2 is provided with a diffusion member 222, and the diffusion member 222 is provided with a receiving cavity 2225 for receiving the optoelectronic module 2, and the diffusion member 222 is fixedly connected to the supporting unit 1, and the optoelectronic module 2 is arranged between the diffusion member 222 and the supporting unit 1. The diffusion member 222 is made of a material with light transmission characteristics and light diffusion performance, and is preferably made of a PP (Polypropylene) diffusion plate, which has high light transmission and good light diffusion effect, and can avoid the problem of glare. The diffusion member 222 can be arc-shaped or square-shaped according to the specific implementation effect, which can enhance the light diffusion effect and improve the appearance of the lamp.

[0304] As Figure 60A shown is a cross-sectional view of the LED lighting lamp along the vertical direction of the optoelectronic module in an embodiment of the present application, as shown in the figure, the optoelectronic module 2 in the receiving cavity 2225, at least part of the light emitted therefrom is directed to the back plate 12, that is, at least part of the light emitted from the diffusion member 222 is projected to the back plate 12, and after being reflected by the back plate 12, it is finally emitted from the LED lighting lamp.

[0305] In another embodiment of the present application, the back plate 12 has a reflection and projection function, and at least part of the light emitted from the optoelectronic module 2 is reflected by the back plate 12 after being processed by the diffusion member 222, and at least part of the light is transmitted through the back plate 12 and projected onto the base 11, and then emitted from the back plate 12 after being reflected by the base 11.

[0306] As Figure 55 and Figure 58As shown, preferably, the inner or outer wall of the diffuser 222 can be patterned, that is, a specific pattern structure is formed on the inner or outer wall, such as a striped structure, dotted protrusions or depressions, a frosted structure, etc., which is an array of micro-optical structures, i.e., a micro-array optical structure. When the photoelectric module 2 is housed in the receiving cavity 2225 and emits light, the excessively concentrated light can be effectively dispersed after the diffuse reflection or refraction of the patterned structure on the inner or outer wall, avoiding the problem of glare or dazzling light caused by a point light source in the lamp body, so that it has a uniform light emission effect and the light is softer. In this embodiment, preferably, a striped structure 2227 is provided on the inner wall of the diffuser 222.

[0307] like Figure 7 The simplified light path emission diagram shown indicates that the first light-emitting component 211” emits light upwards, which, together with the arc-shaped structure of the diffuser 222 and the patterned structure thereon, enhances the light diffusion effect and avoids glare. As for the light emitted by the second light-emitting component 212”, together with the reflective effect of the lower surface of the upper end face of the light source plate 201 and the inclined surface of the protrusion 123, all the side-emitting light is reflected to the side of the lamp, improving the uniformity of illumination and reducing the dark area.

[0308] like Figures 54-56 As shown, diffuser 222 has diffuser end caps 22210 at both ends along its length. The bottom of diffuser end caps 22210 is attached to the support unit 1. A locking groove 222101 is provided inside the diffuser end cap 22210 at the position corresponding to the position of the light source plate 201. The light source plate 201 is locked in the locking groove 222101. The diffuser 222 and the photoelectric module 2 are connected as one unit by the diffuser end caps 22210, which effectively prevents light leakage at both ends of the self-transmitting diffuser 222.

[0309] like Figures 54-57 As shown, the support unit 1 has a second end cap 4 at both axial ends. The diffuser end cap 22210 has a plug block 222102 on its outer side. The second end cap 4 has a plug hole 131 at the position corresponding to the plug block 222102 on its inner side. The mutual cooperation between the plug block 222102 and the plug hole 131 makes the installation and fixing between the diffuser end cap 22210 and the second end cap 4 quicker and more convenient. The plug block 222102 is inserted into the corresponding plug hole 131 to realize the connection between the diffuser end cap 22210 and the second end cap 4, and complete the assembly of the overall structure of the lamp body.

[0310] like Figure 54 As shown, a sensing device 6 may also be provided on the diffuser end cap 22210. The sensing device 6 can sense the external environmental conditions, such as light intensity, temperature, humidity and other data, and adjust the light output state of the lamp according to the external data.

[0311] like Figure 54 andFigure 55 As shown, in another specific embodiment, the LED lighting lamp can also be provided with an emergency power module 34, which is arranged on the power module 34 and shares the power circuit board 41; the emergency power module 34 includes an emergency power 341 and an energy storage battery 52 arranged on the power circuit board 31, and the emergency power 341 and the energy storage battery 52 are connected by wires and are electrically connected, so that once the first power supply 32 is powered off, the emergency power 341 is triggered to start and continue to supply power. Preferably, the emergency test switch 343 and the emergency display lamp 344 are arranged on the diffusion member end cover 22210, the emergency test switch 343 is used as a switch required for safety and maintenance inspection of the LED lighting lamp, and after the emergency test switch 343 is pressed, the emergency display lamp 344 is bright to show whether the emergency power module 34 is working normally.

[0312] As Figure 63A In an embodiment of the present application, the lampshade is a square state, and the lampshade surface brightness diagram is shown, and the brightness changes when the distance between the lamp beads and the distance between the lamp beads and the lampshade changes. The Figure 63A The square lampshade surface brightness diagram is shown when the distance between the lamp beads and the lampshade is 32.8mm, and the distance between the lamp beads is 8mm, Figure 63B The 2.5m distance illuminated surface illuminance diagram is shown, Figure 63C The light distribution curve at this time is shown.

[0313] Figure 64A The lampshade surface brightness diagram is shown when the distance between the lamp beads and the arc-shaped lampshade is 32.8mm, Figure 64B The 2.5m distance illuminated surface illuminance diagram is shown, Figure 64C The light distribution curve at this time is shown.

[0314] In other embodiments, the top surface and the side surface of the diffusion member 222 have the same light transmittance.

[0315] In other embodiments, the top surface and the side surface of the diffusion member 222 can have a large difference in light transmittance, such as transparent or translucent.

[0316] In another embodiment of the present application, referring to Figure 24BIn an embodiment of the present application, the base 11 has at least one protrusion with a trapezoidal or V-shaped cross section in the length or width direction towards the side close to the back plate 12, i.e. a protrusion structure integrally formed on the base 11, which has an inclined surface pointing to the back plate. At least one light emitting unit 21 can be arranged on the inclined surface. Of course, it can also be said that at least one first or second light emitting assembly is arranged on the inclined surface and adheres to the inclined surface. At least part of the light emitted by the light emitting unit 21 (or the first or second light emitting assembly) points to the back plate 12, which can be an inclined plane or an arc surface. A light processing unit 22 is further arranged on the base 11. The light processing unit 22 can be a diffusion member 222, which covers at least part of the light emitting unit 21 and can emit and diffuse the light emitted from the light emitting unit. The back plate 12 has a light reflecting function. At least part of the light processed by the light processing unit 22 is directly emitted from the light processing unit. At least part of the light processed by the light processing unit 22 (or the diffusion member 222) is projected onto the back plate 12, is reflected by the back plate 12, and is finally emitted from the LED lighting lamp. This makes the light emitted by the LED lighting lamp more uniform. In an embodiment of the present application, a power module 3 is arranged on the side of the back plate 12 close to the base 11. The height of the power module 3 is less than or equal to the distance between the highest end of the back plate 12 and the bottom plate 111 of the base 11.

[0317] Please refer to Figure 65 and Figure 66 , Figure 65 is a front view of an LED lighting lamp in an embodiment of the present application, Figure 66 is a back view of an LED lighting lamp in an embodiment of the present application. As shown in Figure 65 , the LED lighting lamp comprises a support unit 1, which serves as the main frame of the LED lighting lamp. Other components of the LED lighting lamp are installed with the support unit 1 as the installation reference, and the support unit 1 is used to determine the overall shape of the LED lighting lamp. In an embodiment of the present application, the support unit 1 is substantially trumpet-shaped, i.e. the opening at one end is smaller than the opening at the other end. A diffusion member 222 is arranged at the end with the smaller opening of the support unit 1. The diffusion member 222 is supported on the support unit 1 and forms a relatively complete light emitting surface together with the support unit 1.

[0318] Please refer to Figure 66 , the support unit 1 is further connected with the base 11, i.e. the base 11 covers the end with the smaller opening of the support unit 1, and the base 11 and the diffusion member 222 abut against each other to form a relatively closed accommodation space, in which part of the electronic components and optical devices are arranged.

[0319] Please see Figure 67 , Figure 67 Figure 1 is a front view of the LED lighting fixture in the embodiment, as shown, the support unit 1 includes a plurality of back plates 12, the back plates 12 are connected end to end to form a cylindrical structure, and the back plates 12 are arranged obliquely relative to the horizontal plane, so that the opening end of the cylindrical structure formed by the back plates 12 is large and the other end is small, that is, a horn-shaped structure is formed. The end of the back plate 12 along the light-emitting direction of the LED lighting fixture, that is, the end with a large opening, is bent along the horizontal direction to form a joint portion 122 with a certain length, the joint portion 122 is flat and forms a flat surface, and the joint portion 122 is usually attached to the installation plane, such as the ceiling, when the LED lighting fixture is installed. The joint portion 122 with a flat surface can make the LED lighting fixture have a better appearance performance in the straight-up line of sight after installation. The other end of the back plate 12, that is, the end with a small opening, is provided with a plurality of connecting portions 124 or at least one connecting portion 124, which extend from one end of the back plate 12 and are used to connect and fix the bottom plate 11. Among them, the connecting portion 124 is provided with at least one opening, which corresponds to the opening on the bottom plate 11, and the bottom plate 11 and the support unit 1 are fixed by respectively penetrating the opening on the connecting portion 124 and the opening on the bottom plate 11 through bolts or rivets. One end of the bottom plate 11 includes at least one first base side wall 112 and two second base side walls 113.

[0320] In the embodiment, the first base side wall 112 is formed by extending the bottom plate 11 to one side, and the second base side wall 113 is separately formed. One first base side wall 112 and two second base side walls 113 are combined with each other to form a semi-closed accommodation space for accommodating the power supply module 3. The semi-closed space formed by the first base side wall 112 and the second base side wall 113, in combination with the back plate 12, forms a relatively sealed space to accommodate the power supply module. In this way, it is not necessary to separately provide a power supply box for accommodating the power supply module 3, thereby reducing the cost of the lamp.

[0321] In this embodiment, a light emitting unit 21 is also included, which is arranged on the bottom plate 11 and is completely covered by the diffusion member 222. It is worth mentioning that the diffusion member 222 is clamped and fixed by the supporting unit 1 and the bottom plate 11, and during the assembly process, the fixation of the diffusion member 222 can be achieved only after the bottom plate 11 and the supporting unit 1 are locked, and the diffusion member 222 does not need to be additionally fixed. In the conventional technology, the diffusion member is generally arranged on one side of a component and is fixed by, for example, gluing or other methods. The other side of the diffusion member is relatively weak in fixation. In this embodiment, the diffusion member 222 is fixed by the clamping and fixing method of the supporting unit 1 and the bottom plate 11, so that the diffusion member 222 is limited on both sides by the components, and the diffusion member 222 has no risk of falling off. In addition, the connection between the diffusion member 222 and the supporting unit 1 and the bottom plate 11 is different from the conventional connection by gluing or welding. The replacement of the components is simple and will not damage the original components.

[0322] Please refer to Figure 68 , as Figure 68 is a structural schematic view of the combination of the bottom plate 11 of the LED lighting lamp and the diffusion member 222 in this embodiment. As shown in the figure, in this embodiment, the first base side wall 112 and the second base side wall 113 form two semi-closed accommodation spaces, at least one of which is used to accommodate the power module 3, and the other can be used to accommodate other electronic components or emergency power supply, etc. The edge of the diffusion member 222 also includes a plurality of (at least one) limiting members 2226, which extend in the direction parallel to the bottom plate 11, and the opening of the smaller segment of the supporting unit 1 interferes with one end of the back plate 12 to limit the movement of the diffusion member 222 in the light emitting direction of the LED lighting lamp.

[0323] Please refer to Figure 69 , as Figure 69 is another perspective structural schematic view of the combination of the bottom plate 11 of the LED lighting lamp and the diffusion member 222 in this application. As shown in the figure, a plurality of (or at least one) reinforcing structures 114 are arranged on the bottom plate 11. The reinforcing structure 114 is a groove-shaped structure, which protrudes in the opposite direction of the light emitting direction of the LED lighting lamp, that is, a groove structure is formed on the surface where the light emitting unit 21 is arranged. The light emitting unit 21 is arranged in the reinforcing structure 114 (groove structure), which can effectively realize the positioning of the light emitting unit.

[0324] Please refer to Figure 70 is a schematic view of the light emitting unit 21 arranged in the reinforcing structure 114. The light emitting unit 21 includes a plurality of first light emitting assemblies 2111, the structure of which is as described above.

[0326] Please refer to Figure 72 Fig. 1 is a structural schematic diagram of an LED lighting lamp according to an embodiment of the present application,

[0327] In an embodiment of the present application, the backboard 12 is a long rectangular panel, and the long edges are bent towards the center to form the arc-shaped backboard 12.

[0328] In an embodiment of the present application, the bottom plate 111 is a flat bottom surface, and the backboard 12 is an arc surface extending to both sides along the bottom plate 111, and the arc surface is bent towards the same side of the bottom plate 111.

[0329] In an embodiment of the present application, the back plate 12 is an arc-shaped back plate, both sides of the bottom plate 111 are provided with the back plate 12, and the two back plates are symmetrically arranged about the bottom plate 111. The side wall 13 cooperates with the back plate 12 to form an arc-shaped groove, and the photoelectric module 2 is arranged in the arc-shaped groove. One side of the side wall 13 is connected with the arc line of the back plate 12, that is, one side of the side wall 13 is an arc-shaped side with the same arc line as the back plate 12, and the other side is a straight side.
