Description

[0001] This application is a divisional application filed with the China Patent Office on September 20, 2023, with application number 2023225622380 and invention name “LED lamp” Technical Field

[0002] The present application relates to the technical field of LED lighting devices, and more particularly to an LED lamp. Background Art

[0003] LED lamps refer to lamps that use light-emitting diodes as light sources. They are widely used because of their advantages such as energy saving and long life. Flat lamps in LED lamps are a type of lighting fixture that can be embedded in the ceiling. They are popular among people because of their lightness, thinness, and large irradiation area.

[0004] In the prior art, the flat panel lamp 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 illuminated indoor environment is uneven. For example, the indoor environment will appear too bright in the middle area and darker in the surrounding areas.

[0005] In order to solve the above-mentioned problem of uneven light, bat-wing diffusers are added on the market to achieve the bat-wing light distribution of the light source. This bat-wing diffuser is a diffuser with a special micro-prism surface structure, which is expensive and has a poor appearance. In addition, due to its double-sided microstructure, the bat-wing diffuser needs to be fixed with a transparent plate as support. In order to form a bat-wing light pattern, the bat-wing diffuser needs to be designed according to the position and curvature of the light-emitting surface of the light source during use. Therefore, the structural design of the lamp is also relatively complicated.

[0006] In addition, the flat panel lights in the prior art set the light source in the middle area, which will also cause uneven illumination of the light-emitting surface due to the limited emitting angle of the lamp beads, further resulting in a dark area where some areas on the chassis of the flat panel lights (especially the surrounding areas) are not illuminated by light. In order to solve the problem of dark areas, the market generally changes the light emission direction of the lamp beads by adding lenses, but this method adds an extra lens structure, making the structural design of the flat panel lights complicated and the shape unsightly.

[0007] In summary, in view of the deficiencies and defects of the flat panel lamps in the prior art, how to design the flat panel lamps to form a uniform light pattern and / or avoid the appearance of dark areas is a technical problem that needs to be urgently solved by the technicians of this application.

[0107] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0108] In the following description, reference is made to the accompanying drawings, which describe several embodiments of the present application. It should be understood that other embodiments may also be used, and that changes in module or unit composition, electrical and operational aspects may be made without departing from the spirit and scope of the present disclosure. The following detailed description should not be considered restrictive, and the scope of the embodiments of the present application is limited only by the claims of the published patents. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0109] It will be understood that, although the terms first, second, etc. can be used to describe various elements or parameters in this article in some instances, 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, the first element can be referred to as the second element, and similarly, the second element can be referred to as the first element without departing from the scope of the various described embodiments. The first element and the second element are both describing an element, but unless the context clearly indicates otherwise, they are not the same element. The terms "or" and "and / or" used in this article are interpreted as inclusive, or mean any one or any combination. Therefore, "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. Only when the combination of elements, functions, steps or operations is inherently mutually exclusive in some way, will there be an exception to this definition.

[0110] It will be understood that when an element, such as a layer, region, or substrate, is referred to as being "on" or extending "onto" another element, the element may be directly on or directly extending onto the other element, or intervening elements may also be present. Conversely, when an element is referred to as being "directly on" or "extending directly onto" another element, there are no intervening elements. It will also be understood that when an element is referred to as being "connected" or "coupled" to another element, it may be directly connected or coupled to the other element, or there may be intervening elements. Conversely, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements.

[0111] Relative terms such as "below" or "above" or "upper" or "lower" or "horizontal" or "vertical" may be used herein to describe the relationship of one element, layer or region to another element, layer or region as illustrated in the figure. It will be understood that these terms are intended to cover different device orientations other than the orientation depicted in the figure. In this application, the "vertical", "horizontal" and "parallel" are defined as: including the situation of ±10% based on the standard definition. For example, vertical usually refers to an angle of 90 degrees relative to a reference line, but in this application, vertical refers to a situation within 80 to 100 degrees.

[0112] The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. When used herein, the singular forms "a", "an", and "the" are intended to also include the plural forms unless the context clearly indicates otherwise. It will also be understood that when used herein, the terms "comprise", "include", "include" and / or "comprising" specify the presence of stated features, integers, steps, operations, elements and / or parts, but do not exclude the presence or increase of one or more other features, integers, steps, operations, elements, parts and / or combinations thereof.

[0113] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those of ordinary skill in the art to which this application belongs. It will also be understood that the terms used herein should be interpreted as having meanings consistent with their meanings in the context of this specification and the relevant art, and should not be interpreted in an idealized or overly formal sense unless explicitly defined as such in this document. For example, terms such as "support" used in describing some embodiments may also be understood as "support".

[0114] Unless otherwise expressly stated, comparative quantitative terms such as "less than" and "greater than" are intended to encompass the concept of equality. As an example, "less than" may not only mean "less than" in the strictest mathematical sense, but may also mean "less than or equal to".

[0115] The present application discloses an LED lamp in some embodiments, which can be a lighting fixture that can be suspended or fixed to a ceiling or suspended ceiling. Depending on the application, the LED lamp disclosed in the present application can also be called a flat lamp, a chandelier, a recessed lamp, a concave lamp, a recessed lamp, or a ceiling lamp.

[0116] See also Figures 1 to 3 , Fig.23 ,as well as Fig.36 , Figure 1 The diagram shows a front view of an LED lamp in one embodiment of the present application. Figure 2 The figure shows a left side schematic diagram of an LED lamp in one embodiment of the present application. Figure 3 , Fig.23 ,as well as Fig.36The three-dimensional structural schematic diagrams of the LED lamp in one embodiment of the present application are respectively shown. As shown in the figure, the LED lamp includes: a support unit 1 and an optoelectronic module 2 connected to the support unit 1. In some examples, the optoelectronic module 2 is connected to the support unit 1 in a replaceable (detachable) manner so that the optoelectronic module 2 can be replaced for the LED lamp. If the optoelectronic module 2 is damaged, only the optoelectronic module 2 can be replaced, which can reduce the replacement cost compared to replacing the entire lamp. The optoelectronic module 2 can also be connected to the support unit 1 in a non-detachable manner, that is, after the optoelectronic module 2 is fixed to the support unit 1, it cannot be easily disassembled. In other examples, the optoelectronic module 2 can be configured to be quickly installed with the support unit 1, and after installation, the optoelectronic module 2 and the support unit 1 cannot be easily disassembled. In this way, when packaging and transporting, the optoelectronic module 2 and the support unit 1 can be packaged and transported separately, saving packaging and transportation costs, and when selling or using, the optoelectronic module 2 and the support unit 1 can be quickly installed.

[0117] Please refer to 1 to Figure 4 , Figure 4 The figure shows a three-dimensional structure diagram of a support unit in one embodiment of the present application. As shown in the figure, the support unit 1 includes a base 11. Figure 2 and Figure 4 In the embodiment shown, the support unit 1 further includes a back plate 12, which is disposed around the base 11. Alternatively, it can be described as the back plate 12 extending from the base 11 to the periphery. In some embodiments, the back plate 12 can also be referred to as the side wall of the LED lamp. The back plate 12 can be tilted or horizontally disposed relative to the base 11. For example, the tilt angle of the back plate 12 to the base 11 (e.g. Figure 2 The angle in the figure can be set from 0 to 90 degrees. Figure 2 As shown, the inclination angle refers to the angle α between the horizontal section X of the back plate 12 and the base 11. In a more specific example, the inclination of 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, etc. Preferably, it can be set to an angle of 20 degrees.

[0118] In one embodiment, the base 11 is located in the middle area, and the front area of ​​the support unit 1 covered by the base 11 accounts for 15% to 50% of the front area of ​​the support unit 1 (for example, it can be approximately 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%), where the front area refers to the projection area in the direction perpendicular to the support unit 1 (wherein the direction perpendicular to the support unit 1 is defined as the horizontal direction, such as Figure 2 The middle section X is the horizontal section). Considering that in some embodiments, the photovoltaic module 2 includes at least a light-emitting unit, and the light-emitting unit is disposed on the base 11, it can also be understood that in the support unit 1, the front area for the light-emitting area accounts for 15% to 50% of the front area of ​​the support unit 1. More specifically, considering the material cost and the appearance, the front area of ​​the support unit 1 covered by the base 11 is set to account for about 33.3% of the front area of ​​the support unit 1 (33.3% can be understood as an approximate value of 1 / 3).

[0119] See also Figure 1 , Figure 3 , Figure 5 , Fig.24A ,as well as Fig.37 , Figure 5 , Fig.24A ,as well as Fig.37 They are respectively shown as schematic diagrams of the disassembled structure of an LED lamp in an embodiment of the present application. As shown in the figure, the optoelectronic module 2 includes a light-emitting unit 21 and a light processing unit 22. The light-emitting unit 21 is used to emit light for illumination, and the light processing unit 22 is used to process the light emitted by the light-emitting unit 21 and then emit it. For example, the light processing unit 22 can change the light-emitting path of the light-emitting unit 21, that is, the light processing unit 22 is arranged on the light-emitting path of the light-emitting unit 21. The base 11 of the support unit 1 at least provides an installation position for the light-emitting unit 21. In other words, at least the light-emitting unit 21 is arranged on the base 11 or in the accommodation space of the base 11. In the present application, the side of the support unit 1 for arranging the light-emitting unit 21 is defined as the front side, and the other side relative to the front side is defined as the back side. The base 11 can also provide an installation position for the light processing unit 22. In other words, the light processing unit 22 can also be configured on the base 11 or in the accommodation space formed by the base 11. Of course, in other embodiments, the base 11 may also provide an installation location or accommodation space for other components, units, modules, modules or members in the optoelectronic module 2. It should be understood that Figure 5 This is only an example of a split structure. In some embodiments, the optoelectronic module 2 may not be provided with the light processing unit 22 .

Figure 7 Shown is a schematic diagram of the three-dimensional structure of a light-emitting unit in an embodiment of the present application. As shown in the figure, the base 11 of the support unit 1 has a bottom surface 111. The light-emitting unit 21 includes a first light-emitting component 211. The first light-emitting component 211 is configured on the bottom surface 111. The first light-emitting component 211 may include a first circuit board 2111 and a first light-emitting body 2112. Among them, the first light-emitting body 2112 may be an LED lamp bead, or other types of LED light-emitting monomers. The first circuit board 2111 is attached (for example, directly attached or attached through an intermediate medium) to the bottom surface 111. The first light-emitting body 2112 can be set to a plurality of first light-emitting bodies 2112, and the plurality of first light-emitting bodies 2112 are evenly distributed on the first circuit board 2111. Figure 6 and Figure 7 In the example, 24 first light-emitting bodies 2112 are set as an example. Those skilled in the art can also set any number of first light-emitting bodies 2112 according to actual needs. In some embodiments, the first light-emitting components 211 can be set to at least two groups, that is, the light-emitting unit has at least two groups of light-emitting components. The at least two groups can be understood as two or more groups, and each group is arranged on the bottom surface 111 in parallel. For example, the first light-emitting components 211 can be set to 2 groups, 3 groups, 4 groups, 5 groups, or 6 groups, etc. Figure 6 and Figure 7 In the embodiment shown, the first light emitting components 211 are arranged in 4 groups. Of course, in other embodiments, such as under the limitation of some specific installation environments or lamp structures, the first light emitting components 211 may also be arranged in only 1 group. In other words, those skilled in the art may select any number of groups to be arranged on the bottom surface 111 according to actual needs under the inspiration of the above embodiments of the present application. In another embodiment, the spacing distances between the first light emitters 2112 are at least two.

[0121] See also Figure 6 and Figure 8 , Figure 8Shown is a light pattern diagram of the first light-emitting component in one embodiment of the present application. As shown in the figure, the light pattern of the first light-emitting component 211 is a distribution in which the light intensity is strongest at an exit angle of 0 degrees, and the light intensity decreases continuously with the increase of the exit angle. For example, the light pattern distribution of the first light-emitting component 211 is a Lambertian light pattern or a near-Lambertian light pattern. In the example in which the light-emitting unit 21 only includes the first light-emitting component 211, the light pattern distribution of the LED lamp also corresponds to the light pattern distribution of the first light-emitting component 211. This will make the lighting of the LED lamp uneven, and the luminous intensity in the area directly below the first light-emitting component 211 is higher. When applied to a space that needs to be illuminated, a central light spot phenomenon will appear in the space where the middle area of ​​the LED lamp is brighter and the surrounding areas are darker.

[0122] The area directly below the first light emitting component 211 mentioned here and in the following can be understood as the area of ​​the preset beam angle of the first light emitting component 211. In some examples, the preset beam angle can be set to 10 degrees to 60 degrees (for example, approximately 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), taking the preset beam angle as 10 degrees as an example, the area directly below the first light-emitting component 211 refers to the area in the range of -5 degrees to 5 degrees with the center line of the beam (i.e., the main axis of the maximum light intensity) as 0 degrees. In some examples, the preset beam angle can also be set with light intensity as a reference, and the preset beam angle can be set to an angle of 20% of the maximum light intensity to an angle of 60% of the maximum light intensity. Taking the angle set to 20% of the maximum light intensity as an example, the area directly below the first light-emitting component 211 refers to the angle area between two beams with a light intensity equal to 20% of the maximum light intensity. It should be understood that in the embodiment where the first light-emitting component 211 is arranged in the middle area of ​​the LED lamp, the area directly below the first light-emitting component 211 can also be referred to as the middle area of ​​the LED lamp or the area directly below the LED lamp, which will not be elaborated later.

[0123] The surrounding area of ​​the first light-emitting component 211 mentioned here and later (for example, the left and right front and back sides, also referred to as the surrounding area) can be understood as the surrounding area of ​​the area directly below the first light-emitting component 211. In this application, it is allowed that the surrounding area and the area directly below can overlap within a certain range at the junction. Relative to the position of the first light-emitting component 211, the surrounding area of ​​the first light-emitting component 211 includes: the front area, the rear area, the left area, the right area, etc. When it comes to a specific orientation in the surrounding area, this application uses orientation nouns in some embodiments (such as front, back, left, right, etc.). When a specific orientation is not specifically indicated, this application can directly use the surrounding area in some embodiments. It should be understood that in the embodiment where the first light-emitting component 211 is configured in the middle area of ​​the LED lamp, the surrounding area of ​​the first light-emitting component 211 can also be referred to as the surrounding area of ​​the LED lamp, which will not be repeated later.

[0124] Given that Figure 8 In the case of the central light spot as described above, in some embodiments, the light-emitting unit 21 may further include a second light-emitting component, and the light distribution of the first light-emitting component and the second light-emitting component are combined to form a light distribution of the LED lamp by designing the structure and / or parameters of the supporting unit and / or the optoelectronic module in the LED lamp, thereby eliminating the problem of Figure 6 , Figure 8 , and the central light spot phenomenon described in the description thereof, greatly improves the illumination uniformity of the LED lamp. More specifically, in some embodiments, by setting the relative positions of the first light-emitting component and the second light-emitting component, the light distribution of the LED lamp formed by the combination of the light distribution of the two is relatively uniform, for example, a bat wing light type or a near bat wing light type. Among them, the bat wing light type refers to the light distribution spreading out to both sides like a bat wing, showing that the light intensity in the middle area (i.e., the area with a smaller exit angle) is slightly lower, and the light intensity in the two side areas (i.e., the area with a larger exit angle) is slightly higher. The near bat wing light type refers to the light distribution of a non-ideal bat wing type. Although its light distribution does not show the standard situation of slightly higher light intensity on both sides, the overall light distribution shows that the light intensity in the middle and on both sides is not much different, or in other words, the difference is within the acceptable range of uniformity. The bat wing light type or the near bat wing light type can help the lamp achieve high uniformity of lighting, and enable the two lamps to be installed with a larger spacing.

[0125] In one embodiment, see Figure 5 , Figure 7 ,and Fig. 9 , Fig. 9It is a schematic diagram of a three-dimensional structure of the cooperation between the light-emitting unit and the supporting unit in one embodiment of the present application, wherein the second light-emitting component 212 is arranged on the base 11, and is arranged on the peripheral side of the first light-emitting component 211, and is arranged obliquely relative to the first light-emitting component 211. Here, the peripheral side of the first light-emitting component 211 refers to the peripheral side of the area occupied by the first light-emitting component 211. When the first light-emitting component 211 is arranged in multiple groups, the peripheral side refers to the peripheral side of the area occupied by each first light-emitting component 211 as a whole, such as the peripheral side of the bottom surface 111. Among them, with reference to the light emitting direction, the oblique arrangement of the second light-emitting component 212 relative to the first light-emitting component 211 refers to tilting the light emitting side of the second light-emitting component 212 toward the light emitting side of the first light-emitting component 211. In other words, the light emitted by the second light-emitting component 212 is mainly distributed in the peripheral area of ​​the first light-emitting component 211. That is, if the first light-emitting component 211 contributes to the light intensity of the middle area of ​​the LED lamp, the second light-emitting component 212 mainly contributes to the light intensity of the peripheral area of ​​the LED lamp, thereby greatly improving the uniformity of the light intensity distribution of the LED lamp and avoiding the central light spot phenomenon. Of course, in other embodiments, the first light-emitting component 211 and the second light-emitting component 212 can also be spaced apart or closely arranged up and down.

[0126] like Figure 7 As shown, the second light-emitting component 212 may include a second circuit board 2121 and a second light-emitting body 2122. The second light-emitting body 2122 may be an LED lamp bead or other types of LED light-emitting monomers. The second circuit board 2121 is attached (for example, directly attached or attached through an intermediate medium) to the base 11, and the second light-emitting body 2122 may be provided in a plurality of pieces, and the plurality of second light-emitting bodies 2122 are evenly distributed on the second circuit board 2121. Figure 7 and Fig. 9 In the example, 24 first light emitters 2122 are provided, and those skilled in the art may also provide any number of second light emitters 2122 according to actual needs. In some embodiments, the second light emitting components 212 may also be provided in multiple groups, each group surrounding and tilted relative to the first light emitting component 211 and provided on the side of the first light emitting component 211.

[0127] 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 where the second light-emitting component 212 is located form a certain angle with the mounting surface where the first light-emitting component 211 is located.

[0128] See also Figure 2 , Figures 9 to 11 , Fig.10 Show this application Fig. 9 A partial enlarged view of the embodiment shown, Fig.11The cross-sectional structure diagram of the LED lamp in one embodiment of the present application is shown in the figure. As shown in the figure, the base 11 further has a first side wall 112, that is, the base 11 has a bottom surface 111 and a first side wall 112, the first side wall 112 is formed by extending from the edge of the bottom surface 111 toward the light emitting direction (i.e., the front direction of the support unit 1), and the first side wall 112 has a first inclination angle β relative to the bottom surface 111. The first light-emitting component 211 is arranged on the bottom surface 111 (i.e., the bottom surface 111 can be understood as the mounting surface of the first light-emitting component 211), and the second light-emitting component 212 is arranged on the first side wall 112 (i.e., the first side wall 112 can be understood as the mounting surface of the second light-emitting component 212), so that the inclination angle of the second light-emitting component 212 relative to the first light-emitting component is the first inclination angle β. The first side wall 112 can be set to multiple groups, and the second light-emitting component 212 can also be set to multiple groups corresponding to the number of the first side wall 112, so as to emit light in different directions. For example, the bottom surface 111 of the base 11 is configured as a polygon, and the base 11 has a plurality of first side walls 112 corresponding to the number of sides of the polygon, and each first side wall 112 is correspondingly provided with a second light emitting component 212. Figures 9 to 11 In the illustrated embodiment, the bottom surface 111 of the base 11 is configured as a quadrilateral, and the base 11 has four groups of first side walls 112 , and a second light emitting component 212 is correspondingly disposed on each group of first side walls 112 .

[0129] In order to make the light intensity distribution of the LED lamp meet the uniformity requirement, the first inclination angle β of the first side wall 112 relative to the bottom surface 111 is set to 15 degrees to 45 degrees (for example, it can be approximately 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 component 211 and the second light-emitting component 212 are equivalent to being on the same plane (for example, Fig.11If the light is emitted in the manner of the horizontal cross section X in the figure, the light emitted by the second light-emitting component 212 and the first light-emitting component 211 will be more dispersed. For example, the light emitted by the second light-emitting component 212 is mainly distributed on one side that is a certain distance away from the light emitted by the first light-emitting component 211. Not only can it not improve the lighting uniformity of the LED lamp, but it may even cause the LED lamp to have multiple light spots during lighting, thereby exacerbating the lighting unevenness of the LED lamp. If the first inclination angle β is greater than 45 degrees, then in one case (the difference between the first inclination angle β and 45 degrees is too large, for example, greater than 60 degrees) most of the light emitted by the second light-emitting component 212 will be directed toward the accommodation space formed by the support unit 1. In this way, it is easy to be blocked by some parts, units, modules, components, etc. arranged on the support unit 1. For example, in the case of Figure 5 As shown in , in the example where the light processing unit 22 is provided on the light emitting unit 21, most of the light emitted by the second light emitting component 212 will be blocked by some components in the light processing unit 22; another situation (the first tilt angle β is not much different from 45 degrees, for example, less than 60 degrees) will cause most of the light emitted by the two light emitting components (211, 212) to be concentrated in the same area, and both will fail to enhance the illumination uniformity of the LED lamp, and it is difficult to form a bat wing light type or a near bat wing light type. In this embodiment, more preferably, the first tilt angle β can be set to 30 degrees to 45 degrees. The first tilt angle β set in this range can enable the LED lamp to present a bat wing light type or a near bat wing light type. Furthermore, in a specific example, the first tilt angle β can be set to 20 degrees.

[0130] It should be noted that, in the embodiment with multiple groups of first side walls 112, each group of first side walls 112 is generally extended toward the periphery of the bottom surface 111, such as Fig.10 and Fig.11 As shown, there are 4 groups of first side walls 112, and the 4 groups of first side walls 112 are respectively extended to the front, back, left and right of the bottom surface 111, and respectively form a first inclination angle β with the bottom surface 111. The positions of the 4 groups of first side walls 112 are respectively defined as front, back, left and right, wherein, from the perspective of the figure, the position of the first side wall 112 located on the upper side is defined as the front, the position of the first side wall 112 located on the lower side is defined as the back, the position of the first side wall 112 located on the left side is defined as the left, and the position of the first side wall 112 located on the right side is defined as the right. It should be understood that what is shown in the figure is only an example, and each group of first side walls 112 does not necessarily need to be set with the same first inclination angle β, and it is only necessary that the first inclination angle β of each group of first side walls 112 relative to the bottom surface 111 is 15 degrees to 45 degrees.

[0131] See also Fig.12 and Fig.13 , Fig.12 This application is displayed in Fig.11The schematic diagram of light emission of the LED lamp in the embodiment shown is as follows: Fig.13 This application is displayed in Fig.11 The light pattern diagram of the LED lamp in the illustrated embodiment, wherein, for the convenience of description and illustration, Fig.12 The second light emitting assembly 212 disposed on the left first side wall 112 and a group of first light emitting assembly 211 attached to the middle of the bottom surface 111 are used as examples to illustrate the light emission of the LED lamp. The principles of other groups of first light emitting assembly 211 and second light emitting assembly 212 are similar and will not be described in detail. Fig.13 The diagram shows a light pattern formed by the combination of all groups of first light-emitting components 211 and second light-emitting components 212. As shown in the figure, the light emitted by the first light-emitting component 211 is mainly concentrated in the area directly below the first light-emitting component 211, which is also referred to as the middle area of ​​the LED lamp in some examples. The second light-emitting component 212 located on the left side is inclined to the first light-emitting component 211, so the light emitted by the second light-emitting component 212 located on the right side should be mainly distributed in the right side area of ​​the first light-emitting component 211, the light emitted by the second light-emitting component 212 located on the front side should be mainly distributed in the front area of ​​the first light-emitting component 211, and the light emitted by the second light-emitting component 212 located on the rear side should be mainly distributed in the rear area of ​​the first light-emitting component 211, so that the light emitted by the second light-emitting component 212 is mainly distributed in the surrounding area of ​​the first light-emitting component 211. As shown Fig.12 and Fig.13 As shown, the first light-emitting component 211 contributes to the light intensity of the middle area of ​​the LED lamp, and the second light-emitting component 212 mainly contributes to the light intensity of the peripheral area of ​​the LED lamp. In the light pattern of the LED lamp, the difference in light intensity between the middle and peripheral areas is not large (for example, in the range of -40 degrees to 40 degrees, the difference in light intensity is within an acceptable range of uniformity), which greatly improves the uniformity of the light intensity distribution of the LED lamp and avoids the occurrence of a central light spot phenomenon.

[0132] In some embodiments, as described above, the optoelectronic module 2 may further include a light processing unit 22, and the light processing unit 22 is used to process the light emitted by the light emitting unit 21. The light processing unit 22 is disposed on the base 11. In order to provide an adapted accommodation space or position, in some embodiments, such as Figures 9 to 11 As shown, the base 11 further has a second side wall 113, which is connected to the first side wall 112 and has a second inclination angle γ relative to the first side wall 112. In other words, the second side wall 113 is formed by bending the first side wall 112 toward the light emitting direction (also referred to as the front direction of the support unit) and then continuing to extend. Figures 9 to 11In the illustrated embodiment, the number of the second side walls 113 is consistent with the number of the first side walls 112, that is, the bottom surface 111 of the base 11 is set as a quadrilateral, the first side walls 112 are set as 4 groups corresponding to the four sides of the quadrilateral, and the second side walls 113 also have 4 groups. Of course, those skilled in the art can also design the number of the second side walls 113 to be different from that of the first side walls 112 according to the actual shape design, and the present application does not limit this.

[0133] It should be noted that, in some embodiments, the second side wall 113 can also serve as a reflection surface for the light emitted by the second light emitting component 212, so as to reflect the light emitted by the second light emitting component 212 at a larger angle back to the surrounding area of ​​the light emitted by the first light emitting component 211, such as Fig.12 As shown, the light m is formed by the light emitted by the second light-emitting component 112 on the left side being projected onto the second side wall 113 and then reflected, so that the second side wall 113 can make the light emitted by the second light-emitting component 212 more concentrated in the surrounding area of ​​the light-emitting first light-emitting component 211, thereby improving the uniformity of the light output of the LED lamp.

[0134] In one embodiment, the light processing unit 22 includes a beam control component, and the beam control component is used to change the light emission path of the light emitting unit to achieve a better light emission effect. In a specific example, the beam control component is arranged on the light emission side of the second light emitting component 212, and is used to change 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 surrounding area of ​​the first light emitting component 211. For example, the beam control component can change the light emitted by the second light emitting component 212 that is projected to the area directly below the first light emitting component 211 or the middle area of ​​the LED lamp to the surrounding area of ​​the first light emitting component 211 or the surrounding area of ​​the LED lamp, and can also gather the light emitted by the second light emitting component 212 with an excessively large angle to the surrounding area of ​​the first light emitting component 211, so that the LED lamp can form a bat wing light type or a near bat wing light type, further improving the light emission uniformity of the LED lamp.

[0135] See also Fig.14 and Fig.15 , Fig.14 The cross-sectional structure diagram of an LED lamp including a beam control component in one embodiment of the present application is shown. Fig.15 This application is displayed in Fig.14 A partial enlarged view of part A in the illustrated embodiment, as shown in the figure, the light processing unit 22 includes a beam control component 221, the beam control component 221 includes a sawtooth lens 2211, the sawtooth lens 2211 is arranged on the light emitting side of the second light emitting component 212, and the number of groups corresponding to the second light emitting component 212 can be set. Figure 14 to Figure 15 In the illustrated embodiment, there are four groups of sawtooth lenses 2211 corresponding to the number of the second light-emitting components 212. The sawtooth lenses 2211 are arranged in parallel with each second light-emitting component 212 (in some embodiments, it can also be understood that the sawtooth lenses 2211 are parallel to the first side wall 112), and the sawtooth lenses 2211 are arranged as long strips extending in the length direction of the second light-emitting components 212, so that the light emitted by each second light emitter of the second light-emitting component 212 can pass through the sawtooth lenses 2211 to change the light emission path of the second light-emitting component 212.

[0136] Each curved surface in the sawtooth lens 2211 faces away from the first light-emitting component 211, and is used to refract part of the light emitted by the second light-emitting component 212, so that part of the light is output at a wider angle (greater than the original emission angle), and further the light emitted by the second light-emitting component 212 is distributed on both sides of the first light-emitting component 211, and hardly contributes to the area directly below the first light-emitting component 211. For details, please refer to Fig.15 Combined with Fig.16 , Fig.16 This application is displayed in Fig.14 Light pattern diagram of the LED lamp in the illustrated embodiment.

[0137] like Fig.15 Taking the working principle of the second light emitting component 212 on the right side as an example, the sawtooth lens 2211 refracts part of the light emitted by the second light emitting component 212 on the right side to be output at a wider angle, so that the original light emission path may be projected to the area directly below the first light emitting component 211 (which can also be understood as the middle area of ​​the LED lamp, such as Fig.16 The light in the range of -10 degrees to 10 degrees is refracted to the left area of ​​the first light emitting component 211 (such as Fig.16 In the range of -15 to -40 degrees), combined Fig.16 As shown, the light emitted by the second light emitting component 212 on the right side is mainly distributed in the left area (for example, Fig.16 -15 to -40 degrees) and right areas (e.g. Fig.16 Similar to the second light-emitting component 212 on the right, the light emitted by the second light-emitting component 212 on the left is also mainly distributed on the left and right sides. The light pattern distribution of the second light-emitting components 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.

[0138] It should be understood that Figures 14 to 16Only the left and right second light emitting components 212 are used as examples for explanation. The working principle of the second light emitting components 212 on the front and rear sides is similar to that of the left and right sides. After the second light emitting components 212 on the front and rear sides are acted upon by their respective corresponding sawtooth lenses 2211, the light emitted will be mainly distributed on the front and rear sides. The light pattern distribution of the first light emitting component 211 can also be obtained as shown below. Fig.16 Similarly, after the second light-emitting components 212 on the front, back, left, and right sides are acted upon by the corresponding sawtooth lenses 2211, the light emitted will be mainly concentrated on the front, back, left, and right sides, that is, the periphery of the light emitted by the first light-emitting component 211. Combined with the light distribution of the first light-emitting component 211, a bat-wing light pattern is also obtained, which will not be repeated here.

[0139] In one embodiment, see Fig.17 , Fig.17 The structure diagram of the sawtooth lens in one embodiment of the present application is shown. As shown in the figure, the sawtooth lens 2211 includes a bottom surface 22111 and a plurality of saw teeth 22112. The bottom surface 22111 has a certain thickness d, and the thickness d can be set to 0.5mm to 2mm (for example, about 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, or 2mm), for example. Figures 14 to 15 In the illustrated embodiment, the thickness d is set to 1 mm. The saw teeth 22112 may be set to 6 to 9, each of which occupies a certain width k (e.g., 3 mm) of the bottom surface and extends upward from the bottom surface 22111. Each saw tooth 22112 is set to be a curved lens having a curved surface and a vertical surface, wherein, in some examples, the vertical surface height h of each saw tooth 22112 may be set to be the same, for example, set to 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, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.7 mm, 4.8 mm, 4 ... In some examples, the vertical heights h of the saw teeth 22112 may be set to be unequal. For example, the vertical heights h of two adjacent saw teeth 22112 may be equal, and the height difference may be set to be approximately 0.2 mm to 0.4 mm.

[0140] In an embodiment where the sawtooth lens 2211 is disposed in an LED lamp, for example, Figure 14 to Figure 15As shown, the curved surface of each sawtooth 22112 of the sawtooth lens 2211 faces away from the first light-emitting component 211. In other embodiments, the curved surface of each sawtooth 22112 of the sawtooth lens 2211 faces toward the direction close to the first light-emitting component 211, see Fig.18 and Fig.19 , Fig.18 It is a partial structural diagram of the sawtooth lens and the second light-emitting unit in one embodiment of the present application. Fig.19 This application is displayed in Fig.18 In the light pattern diagram of the LED lamp in the illustrated embodiment, as shown in the figure, the curved surfaces of the sawtooth 22112 of the sawtooth lens 2211 are arranged toward the direction close to the first light-emitting component 211. Under the effect of the sawtooth lens 2211 on the refraction of part of the light emitted by the second light-emitting component 212 on the right side, although the light that may be projected to the area directly below the first light-emitting component 211 by the original light-emitting path can be refracted to the right area of ​​the first light-emitting component 211, it will also refract part of the light to the area directly below the first light-emitting component 211. Fig.19 From the light pattern diagram on the right, we can see that Fig.18 Under the action of the sawtooth lens 2211 arranged as shown, the light emitted by the second light-emitting component 212 will be distributed on the left and right sides and the area 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 lamp, but also contributes to the light intensity of the middle area of ​​the LED lamp. 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 middle area of ​​the LED lamp. The light pattern distribution of the second light-emitting components 212 on the left and right sides is combined with the light pattern distribution of the first light-emitting component 211 to form a Fig.19 As shown in the left, middle and right light pattern diagram, it can be seen that it is a non-ideal bat-wing light pattern, and its uniformity cannot reach that of the sawtooth lens 2211 and above. Fig.14 and Fig.15 The effect of the arrangement shown.

[0141] It should be understood that Fig.18 and Fig.19 Only the second light emitting components 212 on the left and right sides are used as an example for explanation. The working principle of the second light emitting components 212 on the front and rear sides is similar to that of the left and right sides. After the second light emitting components 212 on the front and rear sides are acted upon by their respective corresponding sawtooth lenses 2211, the light emitted will be concentrated on the front and rear middle sides. Combined with the light distribution of the first light emitting component 211, the same light type distribution as that of the second light emitting components 212 on the front and rear sides can also be obtained. Fig.19 Similarly, after the second light-emitting components 212 on the front, back, left, and right sides are acted upon by the corresponding sawtooth lenses 2211, the light emitted will be concentrated on the front, back, left, right, and middle sides. Combined with the light distribution of the first light-emitting component 211, the same light pattern is obtained. Fig.19Similar light pattern diagrams will not be repeated here.

[0142] See also Fig. 20 and Fig.21 , Fig. 20 The cross-sectional structure diagram of an LED lamp including a beam control component in one embodiment of the present application is shown. Fig.21 This application is displayed in Fig. 20 A partial enlarged view of part B in the illustrated embodiment, as shown in the figure, the light processing unit 22 includes a beam control component 221, and the beam control component 221 includes a TIR lens 2212 (also called a total internal reflection lens), and the TIR lens 2212 is arranged on the light emitting side of the second light emitting component 212, and the number of groups corresponding to the second light emitting component 212 can be set. Figure 18 to Figure 19 In the illustrated embodiment, there are four groups of TIR lenses 2212 corresponding to the number of second light emitting components 212. The TIR lenses 2212 are arranged parallel to each second light emitting component 212 (ie, the TIR lenses 2212 are parallel to the first side wall 112) to change the light emission path of the second light emitting component 212.

[0143] The TIR lens 2212 is used to refract part of the light emitted by the second light emitting component 212, so that part of the light is output at a narrower angle (smaller than the original emission angle), and further the light emitted by the second light emitting component 212 is distributed on both sides of the first light emitting component, and hardly contributes to the area directly below the first light emitting component 211 or the middle area of ​​the LED lamp. For details, please refer to Fig.21 Combined with Fig. 22 , Fig. 22 This application is displayed in Fig. 20 The light pattern diagram of the LED lamp in the embodiment shown. Fig.21 As shown, the TIR lens 2212 refracts part of the light emitted by the second light emitting assembly 212 on the right side to be output at a narrower angle, so that the light that may be projected to the middle area of ​​the LED lamp by the original light emission path is refracted to the right area. Fig. 22 As shown, the light emitted by the second light emitting assembly 212 on the right side is mainly distributed in the left area of ​​the LED lamp (such as Fig. 22 -15 to -20 degrees) and the right side (such as Fig. 20 Similarly, the light emitted by the second light-emitting component 212 on the left is also mainly concentrated on the left and right sides of the LED lamp. The light distribution of the second light-emitting components 212 on the left and right sides is combined with the light distribution of the first light-emitting component 211 to form a bat-wing light pattern.

[0144] It should be understood that Figure 20 to Figure 22Only the left and right second light emitting components 212 are used as an example for explanation. The working principle of the second light emitting components 212 on the front and rear sides is similar to that of the left and right sides. After the second light emitting components 212 on the front and rear sides are acted upon by their respective corresponding TIR lenses 2212, the light emitted will be mainly concentrated on the front and rear sides. The light pattern distribution of the first light emitting component 211 can also be obtained as shown below. Fig. 22 Similarly, after the second light emitting components 212 on the front, back, left, and right sides are acted upon by the corresponding TIR lenses 2212, the light emitted will be mainly concentrated on the front, back, left, and right sides, that is, the surrounding area of ​​the first light emitting component 211. Combined with the light distribution of the first light emitting component 211, the same light pattern distribution is obtained. Fig. 22 The similar bat-wing light pattern will not be described here.

[0145] In one embodiment, the overall height of the TIR lens 2212 is set to be approximately 6 mm to 8 mm, the diameter of the opening on the side facing the second light-emitting component 212 is set to be approximately 2 mm to 6 mm, and the diameter of the opening on the side away from the second light-emitting component 212 is set to be approximately 10 mm to 12 mm. Fig. 20 and 21 In the illustrated embodiment, the height of the TIR lens is set to approximately 7.5 mm, the diameter of the opening on the side facing the second light-emitting component 212 is set to approximately 6 mm, and the diameter of the opening on the side away from the second light-emitting component 212 is set to approximately 12 mm. Those skilled in the art can select a suitable TIR lens based on the actual size requirements of the LED lamp.

Fig.24A The figure shows a schematic diagram of the disassembled structure of an LED lamp in one embodiment of the present application. Fig.25 It is a schematic diagram of a three-dimensional structure of the light emitting unit and the light beam control component cooperating with the support unit in one embodiment of the present application. Fig.26 This application is displayed in Fig.25 A portion of the embodiment shown, Fig. 27 It is a schematic diagram of the cross-sectional structure of an LED lamp in one embodiment of the present application. Fig.28 This application is displayed in Fig. 27 A partial enlarged view of part C in the illustrated embodiment, Fig.29 This application is displayed in Fig. 27 The light pattern diagram of the LED lamp in the embodiment shown. As shown in the figure, the beam control component 221 includes a reflective structure 2213, which is arranged on the light emitting side of the second light emitting component 212, and the number of groups corresponding to the second light emitting component 212 can be set. Figure 23 to Figure 27In the embodiment shown, there are four groups of reflective structures 2213 corresponding to the number of second light-emitting components 212. The reflective structures 2213 are used to gather the light emitted by the second light-emitting components 212 to increase the light intensity of the surrounding area of ​​the first light-emitting components 211. Figure 27 to Figure 29 The reflective structure 2213 reflects the light emitted by the second light-emitting component 212 (that is, the light with a larger light-emitting angle) to achieve a focusing effect on the second light-emitting component 212 (for example, the light emitted by the second light-emitting component 212 is focused within the angle range formed by the reflective structure 2213, as shown in FIG. Fig.28 The angle between the dotted arrows of the two reflective plates along the reflective structure 2213 is further enhanced to further enhance the light intensity of the peripheral area of ​​the first light-emitting component 211, so that the LED lamp presents Fig.29 The batwing light pattern shown in .

[0147] See also Figures 25 to 30 , Fig.30 The three-dimensional structure diagram of the reflective structure and the second light-emitting component in one embodiment of the present application is shown. The reflective structure 2213 includes a first reflective plate 22131 and a second reflective plate 22132. The first reflective plate 22131 and the second reflective plate 22132 are respectively arranged to be inclined toward the two sides of the light emitting center line L of the second light-emitting component 212. Fig.30 As shown in the figure, the inclination angles of the first reflector 22131 and the second reflector 22132 relative to the light emitting center line L of the second light emitting component 212 are marked as θ. The first reflector 22131 and the second reflector 22132 can be connected to the mounting surface of the second light emitting component 212, such as the first side wall 112, or connected to the second circuit board 2121 (in the form of Fig.30 As shown in , it is only necessary to make the first reflector 22131 and the second reflector 22132 respectively located on both sides of the second light emitting body 2122. The first reflector 22131 and the second reflector 22132 respectively form two reflecting surfaces for the light emitted from the second light emitting component 212, thereby reflecting the light whose light emitting angle exceeds the angle formed by the first reflector 22131 and the second reflector 22132, so as to gather the light emitted from the second light emitting component 212 and enhance the light intensity of the surrounding area of ​​the first light emitting component 211.

[0148] In one embodiment, the inclination angle θ of the first reflector 22131 and the second reflector 22132 relative to the light emitting center line L of the second light emitting component 212 can be set to 15 to 25 degrees (for example, approximately 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 degrees), that is, the light emitted by the second light emitting component 212 is concentrated on the reflective structure 2213. The angle range 2θ can be set to 30 to 50 degrees. The inclination angle θ is set within this range to enable the LED lamp to form a better bat-wing light pattern. Fig.31 The following is an example for explanation. Fig.31 The light pattern diagram of the LED lamp with reflectors of different tilt angles in one embodiment of the present application is shown. Fig.31 (a) shows a light pattern of an LED lamp in which the first inclination angle β is set to 45 degrees, and the inclination angles θ of the first reflector 22131 and the second reflector 22132 are respectively set to 15 degrees relative to the light emitting center line L of the second light emitting component 212. At this time, the light pattern of the LED lamp can also present a bat-wing light pattern with a better effect. If it is less than 15 degrees, the reflective structure 2213 will cause the light emitted by the second light emitting component 212 to be over-concentrated, making it difficult to form a bat-wing light pattern. Fig.31 (b) shows a light pattern of an LED lamp in which the first inclination angle β is set to 45 degrees, and the inclination angles θ of the first reflector 22131 and the second reflector 22132 relative to the light emitting center line L of the second light emitting component 212 are set to 25 degrees. Fig.31 In (b), the LED lamp can still present a bat-wing light pattern, but compared to Fig.31 In (a), the effect of the bat-wing light pattern begins to deteriorate. If the inclination angle θ continues to increase to greater than 25 degrees, the reflective structure 2213 will not be able to focus the light output of the second light-emitting component 212 enough, and the light intensity contribution of the second light-emitting component 212 to the surrounding area of ​​the first light-emitting component 211 will be weakened, making it difficult to form a bat-wing light pattern with a better effect.

[0149] It should be understood that Fig.30 and Fig.31 The figure is only an example, and the inclination angle θ of the first reflector 22131 and the second reflector 22132 relative to the light emitting 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 reflector 22131 and the second reflector 22132 are respectively inclined relative to the light emitting center line L of the second light emitting component 212 and the inclination angle θ is 15 degrees to 25 degrees.

[0150] It should be understood that Figures 14 to 30The serrated lens, TIR lens, and reflective structure shown are only examples of the structures included in the beam control assembly. Those skilled in the art can select any suitable component or structure as part of the beam control assembly as needed, as long as the path of part of the light emitted by the second light-emitting assembly can be changed so that the light emitted by the second light-emitting assembly is mainly distributed in the surrounding area of ​​the first light-emitting assembly. This application does not limit this. Of course, in other embodiments, the beam control assembly may also include other components or structures to change the light emission path of the light-emitting unit to achieve a better light emission effect.

[0151] According to any of the aforementioned embodiments, it can be known that the light pattern distribution of any two relative groups of second light-emitting components 212 combined with the light pattern distribution of the first light-emitting component 211 can improve the lighting uniformity of the LED lamp. Therefore, the user can selectively turn on or off any two relative groups or all of the second light-emitting components 212 according to actual lighting needs through a control switch adapted to the LED lamp. In this way, energy can be saved while meeting user needs.

[0152] In some embodiments, the light distribution formed by the LED lamp is related to the first tilt angle β. Under the premise that the first tilt angle β satisfies the uniformity requirement of the light intensity distribution of the LED lamp, the first tilt angle β is positively correlated with the light output angle of the LED lamp, that is, the larger the first tilt angle β is, the larger the light output angle of the LED lamp is. In embodiments or examples where the light distribution of the LED lamp is a bat wing light type or a near bat wing light type, that is, the larger the first tilt angle β is, the bat wing light type or the near bat wing light type has a wider angle. Please refer to Fig.32 , Fig.32 The light pattern diagram of the LED lamps configured with different first tilt angles in one embodiment of the present application is shown. The LED lamps are configured as follows Figure 23 to Figure 27 Take the structure shown as an example, Fig.32 (a) is a light pattern with a first tilt angle β of 30 degrees, Fig.32 (b) is a light pattern with the first tilt angle β configured at 45 degrees. By comparison, Fig.32 (a) Relative Fig.32 For example, the first tilt angle β is smaller, and the angle of the corresponding bat-wing light pattern is also narrower. Similarly, Fig.32 (b) Relative Fig.32 For example, the first tilt angle β is larger, and the angle of the corresponding bat-wing light pattern is also wider. Therefore, those skilled in the art can adaptively configure the first tilt angle β according to the actual application scenario.

[0153] In some embodiments, the power supply characteristics of the first light-emitting component and the second light-emitting component are further set to further improve the uniformity of the light distribution of the LED lamp, for example, the LED lamp presents a better bat-wing light type or a near-bat-wing light type. Wherein, the power supply characteristics refer to the electrical characteristics delivered to the light-emitting unit. In the embodiment or example in which the optoelectronic module further includes a power supply unit, and the power supply unit is connected to an external power supply or a mains supply to supply power to the light-emitting unit, the power supply specifically refers to the electrical characteristics delivered to the light-emitting unit by the power supply unit. Wherein, the power supply characteristics include but are not limited to any characteristics of supply voltage, supply current, supply frequency, etc. In one embodiment, the bat-wing light effect formed by the LED lamp is improved by configuring the power supply characteristics of the second light-emitting component and the first light-emitting component to a preset ratio. For example, the supply voltage of the second light-emitting component and the first light-emitting component can be configured to a preset ratio so that the LED lamp forms a light distribution with weak light intensity in the middle area and strong light intensity in the surrounding area, that is, a bat-wing light type. Furthermore, the preset ratio of the supply voltage of the second light-emitting component to the first light-emitting component can be configured to be 1.5 to 3 (for example, the ratio can be approximately 1.5, 2, 2.5, or 3). More preferably, the preset ratio of the supply voltage of the second light-emitting component to the first light-emitting component can be configured to be 2 to 2.5.

[0154] In order to reduce the glare of the lamp, in some embodiments, such as Figures 1 to 5 ,as well as Figure 23 to Figure 28 ,as well as Fig.39 As shown, the light processing unit 22 also includes a diffusion component 222, and the diffusion component 222 is used to diffuse the light generated by the light emitting unit 21 when it is working. Furthermore, in some embodiments, the diffusion component 222 can also be formed as an outer cover of the light emitting unit 21 to shield and protect 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, that is, the light processing unit 21 can also include multiple outer covers, such as a first outer cover and a second outer cover. This is not limited in the present application.

[0155] In one embodiment, if Figures 1 to 5As shown, the diffusion component 222 can be provided in two parts, including a first diffusion component 2221 and a second diffusion component 2222. The first diffusion component 2221 is provided in the light emitting direction of the first light emitting component 211, and is used to diffuse the light generated when the first light emitting component 211 is working. The second diffusion component 2222 is provided in the light emitting direction of the second light emitting component 212, and is used to diffuse the light generated when the second light emitting component 212 is working. In some examples, the beam control component 221 is provided on the side of the second diffusion component 2222 facing the second light emitting component 212, for example, the beam control component 221 is provided on the second diffusion component 2222 by means of attachment or structural matching, so that the light emitted by the second light emitting component 212 is first acted upon by the beam control component 221 and then diffused by the second diffusion component 2222. In other examples, the beam control component 221 can also be provided on the side of the first diffusion component 2221 facing the first light emitting component 211, and the present application does not limit this. It should be understood that the fact that the number of the diffusion components 222 is two is merely an example. In an embodiment where the light-emitting unit 21 includes more light-emitting components, the diffusion components 222 may also be multiple, greater than two, or at least one diffusion component 222. Each diffusion component performs light diffusion and / or shielding protection on its corresponding light-emitting component, and the present application does not impose any restrictions on this.

[0156] In one embodiment, the first diffusion component 2221 and / or the second diffusion component 2222 may be made of PC material, and have a light diffusion function due to its own material properties. For example, the first diffusion component 2221 and / or the second diffusion component 2222 is set as a milky white PC cover. In other embodiments, the first diffusion component 2221 and / or the second diffusion component 2222 may also be made of transparent materials, such as glass or plastic (such as acrylic sheet), and a diffusion layer is set on its surface to make it have a light diffusion function. Figures 1 to 5 As shown, in a specific example, the first diffusion component 2221 can be set as an inverted trapezoidal cover structure, and the second diffusion component 2222 is set as an annular cover structure conforming to the outer edge of the first diffusion component 2221. When the first diffusion component 2221 and the second diffusion component 2222 are configured on the support unit 1, they are adapted to each other to close the light-emitting surface of the light-emitting unit 21. The second diffusion component 2222 can be provided with a mounting structure on the side facing the second light-emitting component 212, and the mounting structure is used to configure the beam control component 221. It should be understood that Figures 1 to 5 The first diffusion component 2221 and the second diffusion component 2222 shown are only examples, and their structures and shapes can be adaptively adjusted according to aesthetic requirements and the structures and shapes of the specific support unit 1 and the light-emitting unit 21, and the present application does not impose any restrictions on this.

[0157] In some embodiments, the first diffusion component 2221 may 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 component 2222 may 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 component 2221 may also be referred to as a first outer cover, and the second diffusion component 2222 may also be referred to as a second outer cover. Figures 1 to 5 In the illustrated embodiment, the first diffusion component 2221 and / or the second diffusion component 2222 can be respectively used as outer covers to shield and protect the first light-emitting component 211 and the second light-emitting component 212 .

[0158] In one embodiment, if Figure 23 to Figure 28 As shown, the diffusion component 222 can be set to only one, as shown in the figure, the diffusion component 222 includes a third diffusion component 2223, and the third diffusion component 2223 is arranged in the light emitting direction of the first light emitting component 211 and the second light emitting component 212 to diffuse the light generated when the two light emitting components (211, 212) are working. Further, the third diffusion component 2223 can also be formed as an outer cover of the two light emitting components (211, 212) to shield and protect the two light emitting components (211, 212).

[0159] In one embodiment, the third diffusion component 2223 may be made of PC material, which has a light diffusion function due to its own material properties. For example, the third diffusion component 2223 is set as a milky white PC cover. In other embodiments, the third diffusion component 2223 may also be made of transparent materials, such as glass or plastic (such as acrylic sheet), and a diffusion layer is set on its surface to make it have a light diffusion function. Figure 23 to Figure 28 As shown, in a specific example, the third diffusion component 2223 can be configured to include a connection structure 22231 and a cover structure 22232, wherein the connection structure 22231 is formed on the periphery of the cover structure 22232 and is used to connect the third diffusion component 2223 to the support unit 1. For the sake of observability, Figure 23 to Figure 28 In the illustrated embodiment, the cover structure 22232 may be configured as an arc-shaped cover. Of course, the cover structure 22232 may also be configured as, for example Figures 1 to 5 The inverted trapezoidal cover body shown in the figure is not limited in structure and shape in the present application.

[0160] It should be understood that Figures 1 to 5 ,as well as Figure 23 to Figure 28 This is only an example of the diffusion component 222. The design of the number, structure, shape, etc. of the diffusion component 222 only needs to ensure that it does not affect its effect on the light-emitting unit. Figures 1 to 5 ,as well as Figure 23 to Figure 28The relationship between the diffusion component 222 and other parts of the LED lamp is only for illustration, and does not mean that the diffusion component 222 shown must correspond to the structure of the LED lamp in the figure. For example, Figure 23 to Figure 28 The third diffusion component 2223 used can be replaced by Figures 1 to 5 The first diffusion component 2221 and the second diffusion component 2222, Figures 1 to 5 The first diffusion component 2221 and the second diffusion component 2222 used can also be replaced by Figure 23 to Figure 28 The third diffusion component 2223 in.

[0161] In order to prevent the user from observing the lamp beads of the light-emitting unit through the outer cover or the diffusion component, in one embodiment, for example, Figures 5 to 7 ,as well as FIG. 24A to FIG. 26 In the embodiment shown, the first light emitting assembly 211 is arranged in 4 groups, each group is arranged with 24 light emitters, and the maximum distance between the outer cover of the first light emitting assembly 211 and the side facing the first light emitting assembly 211 and the first light emitting assembly 211 is set to 12 cm to 20 cm (for example, approximately 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, or 20 cm), preferably, set to 16 cm. Figure 5 In the example where the outer cover of the first light-emitting component 211 is set as the first diffusion component 2221, the distance between the inverted trapezoidal bottom surface of the first diffusion component 2221 and the first light-emitting component 211 is set to 12 cm to 20 cm. Fig.24A In the example where the outer cover of the first light-emitting assembly 211 is set as the third diffusion assembly 2223, the maximum distance between the third diffusion assembly 2223 and the first light-emitting assembly 211 is set to 12 cm to 20 cm. It should be noted that 12 cm to 20 cm is only a reference range, and the distance is related to the number and distribution density of the first light-emitting assembly 211, the number and distribution density of the light emitters in each group of the first light-emitting assembly 211, etc. Those skilled in the art can select a suitable distance according to the actual design under the guidance of this application.

[0162] In the embodiment where the light-emitting unit 21 includes the first light-emitting component 211, since the light-emitting angle of the first light-emitting component 211 is generally about 120 degrees, the illumination of the first light-emitting component 211 will be uneven, and a dark area will be formed on the supporting unit 1 for supporting / supporting the first light-emitting component 211. Figure 6 As shown, the light emitting unit 21 includes a first light emitting component 211, and the first light emitting component 211 is disposed on the base 11 of the supporting unit 1, and please refer to Fig.33 , Fig.33 This application is displayed in Figure 6The schematic diagram of the light emission of the first light-emitting component 211 in the illustrated embodiment is as shown in the figure. Since the light-emitting angle of the first light-emitting component 211 is approximately 120 degrees, the light emitted by the first light-emitting component 211 cannot illuminate the back panel 12 located around the base 11; or, it can only illuminate a small area of ​​the back panel 12. Therefore, a relatively dark area will be formed on the weak light area of ​​the supporting unit 1.

[0163] It should be noted that the dark area formed on the support unit 1 is due to the limited light-emitting angle of the first light-emitting component. In some embodiments, even if the support unit 1 adopts other structures, the dark area will still be formed on the support unit 1 due to the influence of the light-emitting angle of the first light-emitting component 211. Fig.34 and Fig.35 As shown, Fig.34 It is a schematic diagram of a three-dimensional structure of the first light-emitting component 211 and the supporting unit 1 in one embodiment of the present application. Fig.35 This application is shown in Fig.34 The schematic diagram of light emission of the first light emitting component 211 in the embodiment shown in the figure, in this embodiment, the base 11 of the support unit 1 is set as a planar structure, and the back plate 12 is formed by the base 11 extending toward the periphery, and in order to improve the uniformity of light emission, the back plate 12 is configured as a curved surface, that is, a curved surface formed by the base 11 extending toward the periphery. Of course, according to the different structures and forms adopted by the support unit 1, the base 11 and the back plate 12 can also be named in other ways, for example, in Fig.34 In the illustrated embodiment, the base 11 may also be referred to as the first part / first region of the support unit 1, and the back plate 12 may also be referred to as the second part / second region of the support unit 1, and the present application does not limit this. Fig.34 In the structure of the support unit 1 adopted, Fig.35 As shown, since the first light emitting component 211 is disposed on the base 11 and the light emitting angle is 120 degrees, the curved surface formed by the back plate 12 is hardly irradiated with light, forming a dark area.

[0164] In view of this, in order to solve the problem of forming a dark area on the supporting unit 1 due to the limited light emitting angle of the first light emitting component 211, in some embodiments, for example Figure 36 to Figure 39 The light-emitting unit 21 may further include a third light-emitting group 213 on the basis of including the first light-emitting component 211, and aims to form light in the area outside the light-emitting angle of the first light-emitting component 211 by designing the light-emitting direction of the third light-emitting component 213, thereby increasing the uniformity of light on the surface of the supporting unit 1 and avoiding the occurrence of the above-mentioned dark area.

[0165] It should be noted that, in other embodiments, the light-emitting unit may include other light-emitting components on the basis of including the first light-emitting component and the third light-emitting component, for example, the second light-emitting component described in any of the aforementioned embodiments, that is, the light-emitting unit may include 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 projected onto the dark area on the supporting unit, and there is no limitation on other light-emitting components included in the light-emitting unit.

[0166] In one embodiment, see Figure 36 to Figure 39 , Fig.36 The figure shows a three-dimensional structure diagram of an LED lamp in one embodiment of the present application. Fig.37 This application is displayed in Fig.36 The schematic diagram of the disassembled structure of the LED lamp in the embodiment shown, Fig.38 It is a schematic diagram of a three-dimensional structure of the third light-emitting component 213 and the supporting unit 1 in one embodiment of the present application. Fig.39 This application is displayed in Fig.36 The schematic diagram of the light emission of the first light-emitting component 211 and the third light-emitting component 213 in the illustrated embodiment, 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 the center line of its light beam is perpendicular to the base 11. The third light-emitting component 213 is located in the accommodation space formed by the support unit 1. The center line of its light beam forms a certain angle with the center line of the light beam of the first light-emitting component 211, and faces the support unit 1 to be projected onto the back plate 12 of the support unit 1, that is, the light emission direction of the third light-emitting component 213 is toward the side of the lamp. Furthermore, the center line of the light beam of the third light-emitting component 213 is perpendicular to the center line of the light beam of the first light-emitting component 211, and is projected onto the back plate 12 of the support unit 1. In this embodiment, the light emission direction is based on the center line of the light beam of the light-emitting component as a reference.

[0167] In order to fix the third light-emitting component 213, the supporting unit 1 further includes a supporting structure 14, which is vertically (also referred to as vertically) arranged on the base 11 of the supporting unit 1 and is used to configure the third light-emitting component 213, that is, the third light-emitting component 213 is configured on the supporting structure 14.

[0168] like Figures 38 to 40 As shown, Fig.40The structure diagram of the third light-emitting component and the supporting structure in one embodiment of the present application is shown. The supporting structure 14 can be set as a supporting plate, which is vertically fixed on the base 11. The supporting plate has a first mounting surface 141 and a second mounting surface 142 facing two opposite directions of the supporting unit 1 respectively. Correspondingly, the third light-emitting components 213 are set in at least two groups facing two opposite directions of the supporting unit 1 respectively, that is, at least one group of the third light-emitting components 213 is set on the first mounting surface 141, and at least one group of the third light-emitting components 213 is set on the second mounting surface 142. Among them, the supporting structure 14 can be fixed on the base 11, for example, by screws and nuts, or by adhesives, hot melting or welding, or by snapping on the base 11, for example, by a structure such as a buckle or a hook. In order to adapt to the supporting structure 14, a structure matching the supporting structure 14 can be set on the base 11 to facilitate the installation of the supporting structure 14. The present application does not limit the specific structure.

[0169] The support structure 14 may be disposed in the middle area of ​​the base 11 , and a plurality of groups of first light-emitting components 211 are symmetrically distributed on both sides of the support structure 14 .

[0170] As mentioned above, the third light-emitting components 213 are provided in at least two groups, and the at least two groups can be understood as two or more groups. For example, the third light-emitting components 213 can be provided in 2 groups, 3 groups, 4 groups, 5 groups, or 6 groups, etc., as long as two of the groups are respectively oriented in two opposite directions of the support unit 1, so as to Fig.40 The embodiment shown is taken as an example, and combined with Fig.39 ,exist Fig.39 In the illustrated embodiment, the third light-emitting components 213 are arranged in 6 groups which are symmetrically distributed on the first mounting surface 141 and the second mounting surface 142, that is, 3 groups of third light-emitting components 213 which are distributed in parallel are arranged on the first mounting surface 141, and 3 groups of third light-emitting components 213 are also arranged at positions on the second mounting surface 142 corresponding to the first mounting surface 141. In this way, it can further ensure that the entire front surface of the support unit 1 is evenly illuminated.

[0171] The third light-emitting assembly 213 may include a third circuit board 2131 and a third light-emitting body 2132. The third light-emitting body 2132 may be an LED lamp bead or other types of LED light-emitting monomers. The third circuit board 2131 is attached (for example, directly attached or attached through an intermediate medium) to the base 11, and the third light-emitting body 2132 may be provided in a plurality, and the plurality of third light-emitting bodies 2132 are evenly distributed on the third circuit board 2131.

[0172] Considering that part of the emitted light of the first light-emitting component 211 will be projected onto the edge area of ​​the support unit 1, for example, the side area of ​​the back plate 12 away from the base 11, multiple groups of third light-emitting components 213 continue to project onto this part, which will cause the edge area of ​​the support unit 1 to be too bright. Therefore, in some embodiments, the number of third light-emitting bodies 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 bodies 2132 is reduced. Fig.40 As shown in the example, on the first mounting surface 141, the number of third light-emitting bodies 2132 included in the two groups of third light-emitting components 213 closer to the base 11 is set to 48, and the number of third light-emitting bodies 2132 included in the one group of third light-emitting components 213 farther from the base 11 is set to 26.

[0173] See also Figure 41 to Figure 43 , Fig.41 This application is displayed in Fig.36 The light pattern of the LED lamp in the embodiment shown, Fig.42 This application is displayed in Fig.36 The illuminance diagram of the illuminated surface of the LED lamp at 2.5m in the embodiment shown, Fig.43 This application is displayed in Fig.36 The illuminance diagram of each area in the LED lamp in the embodiment shown. Figure 41 to Figure 43 The third light-emitting group 213 can improve the light uniformity of the lamp and avoid the effect of dark areas.

[0174] like Fig.41 As shown, adding a third light emitting component 213 to the first light emitting component 211 in the LED lamp will not have a negative impact on the light type of the LED lamp, but will make the LED lamp present a Lambertian light type or a near-Lambertian light type. Fig.42 The figure shows the illumination at a distance of 2.5m from the LED lamp, which also meets the illumination characteristics of Lambertian light type or near-Lambertian light type, and the illumination is uniform and soft. Fig.43As shown, multiple areas of the back panel part of the LED lamp are selected and marked as E, F, G, and H respectively, and their corresponding illumination diagrams are marked as (e), (f), (g), and (h), respectively. The area corresponding to the base part of the LED lamp is selected and marked as I, and its corresponding illumination diagram is marked as (i). By comparing the I area with the E, F, G, and H areas, it can be seen that the illumination of the LED lamp meets the characteristics of the Lambertian light type or the near-Lambertian light type, that is, the illumination of the I area is the strongest, and the illumination of the side areas, that is, the E, F, G, and H areas is relatively weak; from the comparison between the E, F, G, and H areas, the illumination of each area in the side area is roughly in the same range, which means that the side area (such as the back panel part) of the LED lamp is uniform as a whole, and there is no dark area in the E, F, G, and H areas.

[0175] In order to reduce the glare of the lamp, as mentioned above, the light processing unit 22 includes a diffusion component 222. Further, in the example Fig.37 In the embodiment shown, the diffusion component 222 includes a fourth diffusion component 2224, which is arranged in the light emitting 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 when they are working. The material and function of the fourth diffusion component 2224 are similar to those of the first light emitting component 211 and the third light emitting component 213. Figures 1 to 5 ,as well as Figure 23 to Figure 28 The diffusion components used are similar, see the previous Figures 1 to 5 ,as well as Figure 23 to Figure 28 The description of the diffusion component in will not be repeated here.

[0176] Please continue reading Fig.39 ,like Fig.39 As shown, since the light-emitting angle of the third light-emitting component 213 is also 120 degrees, only the light of the first light-emitting component 211 contributes to the light intensity in the middle area of ​​the lamp, that is, the third light-emitting component 213 cannot illuminate the area from -30 degrees to 30 degrees with the vertical direction of the supporting structure 14 as the center line, but for the area from -30 degrees to -60 degrees with the vertical direction of the supporting structure 14 as the center line, and the area from 30 degrees to 60 degrees, the first light-emitting component 211 and the third light-emitting component 213 jointly contribute to the light intensity, resulting in a situation where the brightness contrast of the LED lamp is too high, causing dazzle to the human eye.

[0177] In view of this, in one embodiment, if Figure 36 to Figure 45 ,in, Fig.44 This application is displayed in Fig.37 The schematic diagram of the split structure of the light processing unit in the embodiment shown, Fig.45 This application is displayed in Fig.36The schematic diagram of the cross-sectional structure of the LED lamp in the illustrated embodiment, the light processing unit 22 also includes a shading component 223, the shading component 223 includes a shading portion 2231, the shading portion 2231 is arranged in the vertical direction of the supporting structure 14, and is close to the side of the supporting structure 14 away from the supporting unit 1, the shading portion 2231 extends along the length direction of the supporting structure 14, or, it can also be said that it extends along the length direction of the third light-emitting component 213, so that the area where the third light-emitting component 213 is not projected (such as, the area from -30 degrees to 30 degrees with the vertical direction of the supporting structure 14 as the center line) can be shielded to reduce the discomfort of the human eye.

[0178] In one embodiment, the shading portion 2231 is disposed on the outer side of the fourth diffusion component 2224 and is attached to the fourth diffusion component 2224. The shading portion 2231 can be configured as a long metal strip adapted to the outer shape of the diffusion component 2224. In order to facilitate the configuration of the shading portion 2231, the shading component 223 further includes a frame portion 2232, which can be formed by continuing to extend the shading portion 2231. The frame portion 2232 can fix the shading portion 2231 to the outer side of the fourth diffusion component 2224 and can also be used to position the fourth diffusion component 2224 on the support unit 1. In view of this, the fourth diffusion component 2224 can be configured to have an outer surface adapted to the shape of the shading portion 2231 and the frame portion 2232, so as to facilitate the fixing of the fourth diffusion component 2224 without affecting the aesthetics of the lamp.

[0179] The frame portion 2232 and the shading portion 2231 may be an integrally formed metal frame structure, or may be provided with a detachable connection, or a fixed connection, or may be provided with the frame portion 2232 wrapping the shading portion 2231, and the present application does not impose any limitation thereto.

[0180] In other embodiments, the light shielding portion 2231 may also be disposed on the inner side of the fourth diffusion component 224 , and a corresponding accommodation structure is disposed on the fourth diffusion component 2224 to facilitate the configuration of the light shielding portion 2231 .

[0181] In some other embodiments of the present application, the number of the support structures 14 may be a plurality greater than zero, that is, at least one, and the support structures 14 may be arranged in parallel in multiple lines to better solve the dark area problem;

[0182] In some other embodiments of the present application, the number of the supporting structures 14 can be a plurality greater than zero, that is, at least one, and the supporting structures 14 can be arranged in a staggered manner at a certain angle, such as a 90° angle or a 45° angle, etc., for example, arranged in a "cross" structure, or in an "I"-shaped structure in some lamps with large length-to-width ratio differences, so that the light-emitting component 213 located on the supporting structure 14 can be projected to every corner of the LED lamp, greatly reducing the dark area.

[0183] 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 supply or a mains supply. Figure 2 , Figure 3 ,as well as Fig.36 In order to protect the power supply unit, the support unit 1 further includes a power supply module 13, and the power supply module 13 includes a power supply box for providing an installation space for the power supply module. Figure 2 , Figure 3 ,as well as Fig.36 In the example shown, the power module 13 is arranged on the back of the support unit 1, and the power unit is arranged in the power box. In other examples, the power box may not be provided, and the power unit (a single power unit may also be referred to as a power module) is directly arranged on the front or back of the support unit 1. The power unit may include a plurality of electronic components and wiring components, and the plurality of electronic components may be arranged on a circuit board corresponding to the power unit, and some of them may also be arranged on a circuit board corresponding to the light-emitting unit 21, so as to share the same circuit board with the light-emitting unit 21.

[0184] See also Figure 46 to Figure 53 As shown in FIG. 1 , another embodiment of the present application is an LED lamp, which can emit light in multiple angles and can be called a full-light-emitting LED lamp. For example, it can be a linear lamp installed by hanging, or a lamp fixed to a ceiling or suspended ceiling. The spatial position of the LED lamp is as follows: Fig.46 or Fig.50 In the Cartesian coordinate system shown, the LED lamp includes: a supporting unit 1, an optoelectronic module 2 and a diffusion component 222 (of course, the diffusion component can also be called a light processing unit), wherein the plane where the supporting unit 1 is located is parallel to the xy plane, the optoelectronic module 2 emits light roughly along the z-axis direction, and the diffusion component 222 itself is also roughly parallel to the xy plane.

[0185] See also Figures 46 to 47AAs shown, the supporting unit 1 is arched toward one side (for example, along the positive direction of the z-axis) from the edge toward the center to form a back plate 12. Specifically, the open end of the back plate 12 connected to the supporting unit 1 is used as the bottom surface of the back plate, and the closed end of the back plate 12 away from the supporting unit 1 is used as the top of the back plate. The inner wall connecting the bottom surface of the back plate and the top surface of the back plate can be called a side wall. Preferably, the supporting unit 1 and the back plate 12 can be made of metal material or plastic stamping or injection molding 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 aluminum alloy to reduce the overall mass of the LED lamp. At the same time, since the supporting unit 1 and the back plate 12 of the LED lamp are made of aluminum alloy, they have good thermal conductivity 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 lamp and ensuring that the LED lamp is always in a working environment with a better temperature. Generally speaking, the working life of the LED 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 support unit 1 are integrally formed. Of course, in some other embodiments, the back plate 12 and the support unit 1 can be independently formed and then assembled.

[0186] The specific shape of the support unit 1 is not limited, and can be a strip, circle, rectangle or other special-shaped structure. In this embodiment, the overall shape of the support unit 1 is a rectangular structure, and the edge of the support unit 1 can be designed with an upturned folding edge. The folding process forms a rounded edge without additional processing, forming an edge with high safety for use and installation. At the same time, the folding strengthens the structural strength of the edge of the support unit 1 to prevent its deformation. Further, the aesthetics of the support unit 1 can be enhanced by folding. The right angles of the support unit 1 are designed with arc chamfers to avoid sharp corners, so as to improve safety during transportation and installation.

[0187] See also FIG. 47A to FIG. 49B and FIG. 51A to FIG. 53 As shown, the optoelectronic module 2 is arranged in the back plate 12. Preferably, the optoelectronic module 2 is connected in the back plate 12 in a manner that is easy to disassemble. For example, the optoelectronic module 2 and the back plate 12 are connected by a snap / clamping structure, or the optoelectronic module 2 is connected to the top of the back plate 12 by screws, or the optoelectronic module 2 can be adsorbed inside the back plate 12 by magnetic attraction. The detachable connection method is convenient for replacing the optoelectronic module 2 or components on the optoelectronic module 2 for a faulty LED lamp. Of course, the optoelectronic module 2 can also be fixed in the top of the back plate 12, but it cannot be easily disassembled.

[0188] The light emitted by the optoelectronic module 2 is at least partially directed to and projected onto the surrounding areas of the inner wall of the back panel 12 (which can also be understood as the side wall). Specifically, the optoelectronic module 2 includes multiple rows of light strips (or LED lamp beads, LED arrays, that is, multiple light-emitting elements), and the multiple rows of light strips have different light emission directions and light emission angles, that is, at least two angles of light emission. The light strips can be arranged along the x-axis direction and / or the y-axis direction, wherein part of the light strips are directed to the slots and / or the top area of ​​the back panel 12 for light emission, and part of the light strips can be directed to the side walls of the back panel 12 for light emission. By dispersing the light, the dark area around the back panel 12 is brightened until the brightness becomes consistent with that of the central area of ​​the back panel 12, thereby solving the problem of uneven brightness of the LED lamp as a whole and effectively improving the light emission effect. The diffusion component 222 is arranged on the side of the photoelectric module 2 away from the top of the back plate 12, and the diffusion component 222 can cover at least part of the photoelectric module 2, that is, the projection of the diffusion component 222 in the z-axis direction can completely cover or at least partially cover the photoelectric module 2. Preferably, the diffusion component 222 completely covers the photoelectric module 2, so as to facilitate the dispersion of most of the light emitted by the photoelectric module 2, so that the LED lamp emits light more evenly and softly, and avoids the glare and dazzle caused by the excessive concentration of light in the central area of ​​the back plate 12. The photoelectric module 2 includes at least two directions of light emission settings, and at least two light strips (or LED lamp beads, LED arrays, that is, at least two light-emitting elements) are arranged on at least two mounting surfaces. From another perspective, the optical axes or extended lines of the optical axes of at least two light strips (LED lamp beads, LED arrays) intersect, and it should be noted that at least two light strips (LED lamp beads, LED arrays) are arranged on the upper and lower surfaces of the same mounting component.

[0189] The cover surface of the diffusion component 222 is slightly arched in the opposite direction of the z-axis to form a convex structure, that is, an arc-shaped structure, so as to better achieve light diffusion. The diffusion component 222 can be a light-transmitting material. As an example, the diffusion component 222 can also be made of a light-transmitting material such as glass, acrylic, etc., and a diffusion coating or diffusion film is set on its surface to achieve light diffusion. In other words, the diffusion component 222 can also be a partially transparent material. As an example, the diffusion component 222 can be made of a milky white PC cover with a certain degree of haze. Due to its own material properties, the PC cover also has a light diffusion function, thereby making the light output softer.

[0190] See also Fig.47A , Fig.47B and Fig.51AAs shown, in a specific embodiment, a mounting hole 15 is provided at the top of the back plate 12. The mounting hole 15 can be located in the central area and / or edge area of ​​the top of the back plate 12, and the number and shape are not limited. The mounting hole 15 cooperates with connecting parts, such as bolts, hangers, chains, etc., to suspend or install the housing of the LED lamp (i.e., the supporting unit 1 and the back plate 12) to the ceiling, thereby realizing the installation of the LED lamp.

[0191] Of course, the mounting hole 15 can also be set on the bottom surface of the back panel, for example, at the four corners of the bottom surface of the back panel, and the LED lamp is embedded in the installation surface such as the ceiling. The bottom surface of the back panel is basically parallel to the installation surface such as the ceiling, and the height of the back panel 12 is hidden inside the ceiling. The bottom surface of the LED lamp and the ceiling surface have a smooth transition, and the surface difference between the two does not exceed twice the thickness of the edge of the lamp. The overall surface formed between the installation plane and the installation plane after installation is flat, and the visual effect is good.

[0192] Furthermore, a part of the top of the back plate of the back plate 12 is recessed toward the optoelectronic module 2 to form a reinforcing rib 16, that is, there are different height areas on the top surface of the back plate of the back plate 12. By designing the reinforcing rib 16, the structural strength of a part of the top of the back plate of the back plate 12 can be significantly improved, and the problems of warping and deformation during the installation of the LED lighting lamp can be avoided. As an example, the reinforcing rib 16 can be a single or multiple straight line structure, or a mesh or divergent structure, without specific limitation. In one embodiment, the reinforcing rib 16 is a single straight line structure extending along the y-axis direction, and the length of the reinforcing rib 16 does not exceed the length of the top of the back plate of the back plate 12, and there are two mounting holes 15, which are respectively arranged at both ends of the reinforcing rib 16, so that the forces at both ends of the LED lamp are balanced, thereby improving the stability and reliability after installation. Of course, if the back plate 12 itself has sufficient strength, the reinforcing rib 16 may not be provided, thereby simplifying the production process.

[0193] See also Fig.46 and Fig.50 As shown, in some embodiments, the inner wall of the back plate 12 is provided with a reflective surface. Specifically, the reflective surface is the inner wall surface of the top and side wall of the back plate 12. The reflective surface can perform secondary distribution of the light emitted from the optoelectronic module 2 from different light emitting directions and different light emitting angles to improve the uniformity of the light emitted and improve the lighting effect. Preferably, the reflective surface is a diffuse reflective surface, which can be obtained by mechanical processing or chemical treatment. The diffuse reflective surface can reflect light in all directions to disperse the light, thereby reducing glare and local strong light, and at the same time, in the light emitting direction of the LED lamp, most areas have light emitted, avoiding local dark areas, and further improving the light emitting effect.

[0194] See also Figures 46 to 49BAs shown, in the first embodiment, the optoelectronic module 2 of the LED lamp includes a first bracket 210, a first light-emitting component 211' and a second light-emitting component 212', wherein the first light-emitting component and the second light-emitting component can also be described as part of the light-emitting unit.

[0195] See also FIG. 47A to FIG. 47C The first bracket 210 is disposed in the back plate 12. The first bracket 210 is in a "U"-shaped structure. As an example, the first bracket 210 is in a vertical state or a nearly vertical state as a whole and is fixed in the back plate 12. The first bracket 210 includes an inner bracket 2101 and an outer bracket 2102 (see Fig.47C and Fig.49A ), the inner bracket 2101 and the outer bracket 2102 are preferably made of opaque materials, such as opaque plastic, aluminum alloy, carbon fiber, etc., to reduce the weight of the LED lamp, and positions for installing LED light strips are reserved on the inner bracket 2101 and the outer bracket 2102. The inner bracket 2101 and the outer bracket 2102 are arranged at a certain interval and can have different angles relative to the back plate 12. The inner bracket 2101 is surrounded by the outer bracket 2102, and the two can be sheet-like annular structures ("U"-shaped structures).

[0196] The first light-emitting component 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 panel 12, preferably located in the central area of ​​the top of the back panel, and the number of the first light-emitting bodies 2112' can be one, two or more, which are selected according to the actual required lighting brightness. As an example, the first light-emitting body 2112' is horizontally arranged at the reinforcing rib 16 of the back panel 12, and the first light-emitting body 2112' emits light roughly along the z-axis direction and emits it toward the central area of ​​the diffusion component 222. The first light-emitting body 2112" is arranged on the inner edge area of ​​the first bracket 210, that is, the inner bracket 2101, that is, the side of the inner bracket 2101 facing the first light strip 211. The number of the first light-emitting bodies 2112" may be two, four or more, and is adjusted specifically to match the lighting effect of the first light-emitting body 2112'. As an example, there are two first light-emitting bodies 2112" and they are symmetrically arranged on both sides of the first light-emitting body 2112'. The first light-emitting body 2112" may be vertically or obliquely mounted on the inner bracket 2101. Preferably, the inner bracket 2101 is provided with an inclined mounting surface, and the inclined mounting surface enables the light of the second light strip 222 to be emitted more from the diffusion component 222, that is, the overlap between the light-emitting angle and the diffusion cover is higher. 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" intersects with the z-axis in the opposite direction, so that the light is emitted toward the edge area of ​​the diffusion component 222. Through the cooperation of the first light-emitting body 2112' and the first light-emitting body 2112", the diffusion component 222 that illuminates the LED lamp can be evenly illuminated everywhere, thereby improving the lighting effect.

[0197] The second light emitting assembly 212' is an LED light strip. The second light emitting assembly 212' is arranged on the outer edge area of ​​the first bracket 210, that is, the outer bracket 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 installed vertically or tilted on the outer bracket 2102 to achieve light emission in different directions and at different angles. As an example, the number of the second light emitting assembly 212' is four and they are evenly arranged around the outer bracket 2102 in a vertical state. The second light emitting assembly 212' emits light along the x-axis and y-axis directions, evenly illuminating the back plate top area and the side wall area of ​​the back plate 12, so that the brightness of all areas of the entire lamp tends to be consistent, thereby improving the aesthetics and lighting effect of the LED lamp.

[0198] See also Fig.49B FIG. 2 is a schematic diagram of the structure of the first bracket 210 in the present application after removing the diffusion component 222 and other components. Figures 46 to 49AIt can be seen that the inner side of the first bracket 210 in a vertical state can be called the inner bracket 2101, and the outer side in a vertical state can be called the outer bracket 2102. At one end of the inner bracket 2101 and the outer bracket 2102 facing the diffusion component 222, an edge of a certain length extends outward, and the edge can be horizontal or have a certain angle. At the same time, the edge can play a certain shading role. For the convenience of description, it is hereinafter referred to as the shading eaves 24, wherein the angles of the inner bracket 2101, the outer bracket 2102, and the shading eaves 24 can be specifically designed according to actual needs and are not limited to the examples in the embodiments of the present application. The inner bracket 2101, the outer bracket 2102, and the shading eaves 24 can be integrally formed, or they can be individually formed and then assembled into one.

[0199] In general, the optoelectronic module 2 in the full-luminous LED lamp of Example 1 has a simplified structure and beautiful shape. By establishing light-emitting routes in different directions and angles, and cooperating with the back panel 12 and the diffusion component 222 for reflection and divergence, the light-emitting effect of the LED lamp can be effectively improved.

[0200] See also Fig.49A As shown, the angle a between the plane where the first light-emitting body 2112" is located and the plane where the top of the back plate of the back plate 12 is located is greater than 90°. Preferably, the angle a is greater than 90° and less than 150°. Within the range of the angle a, it can be ensured that the first light-emitting body 2112" emits light toward the edge area or the central area of ​​the diffusion component 222. In one embodiment, the angle a between the plane where the first light-emitting body 2112" is located and the plane where the top of the back plate of the back plate 12 is located is 120°. At this time, the light-emitting direction of the first light-emitting body 2112" is more biased toward the edge area of ​​the diffusion component 222, which can reduce the overlap range of the light emission with the first light-emitting body 2112', so that the first light-emitting component 211' disperses the light and improves the uniformity of the lighting.

[0201] In a preferred embodiment, the first bracket 210 extends radially around one end of the back plate top away from the back plate 12 to form a shading eave 24. Specifically, the shading eave 24 is formed by bending one end of the inner bracket 2101 of the first bracket 210 and extending outward in a nearly horizontal state. The shading eave 24 is annular in structure as a whole (see Fig.47A Fig.49B ), after the shading eaves 24 are provided, the shading eaves 24 can form a shading area with the outer side surface of the first bracket 210, and the outer LED light strip is located in the shading area. By providing the shading eaves 24 for shading, the outer LED light strips around can be invisible to the naked eye within a certain range, because the outer LED light strips are hidden in the shading area, and there will be no glare or blinding problems even if the LED lamp is viewed directly.

[0202] In addition to the functions of shading and anti-glare, the shading eaves 24 can also be used as an additional mounting surface. The second light emitting component 212' is not limited to being installed on the external bracket 2102, and can also be horizontally or obliquely arranged on the surface of the shading eaves 24 facing the diffusion component 222 or away from the diffusion component 222 (not shown), to play the role of fill light and avoid dark area problems caused by local areas being too dark. In addition, the shading eaves 24 acting as an additional mounting surface can alleviate the problem of tight mounting positions on the external bracket 2102, which is beneficial to the layout of external light sources and construction operations.

[0203] In a specific embodiment, the diffusion component 222 is an arc-shaped plate-like structure. The diffusion component 222 of this shape is beautiful and can disperse light more evenly, reducing the glare effect of the LED lamp. In addition, the contour area of ​​the diffusion component 222 is larger than the contour area of ​​the first bracket 210 to fully shield the photoelectric module 2. Even if there is no light-shielding eaves 24, the larger area of ​​the diffusion component 222 can also play a shielding role to avoid the glare and dazzling problems caused by the naked eye looking directly at the external LED light strip. The farthest point of the diffusion component 222 along the light-emitting direction of the LED lamp is smaller than any point on the bottom surface of the base 1, that is, the diffusion component 222 is completely contained in the LED lamp.

[0204] See also Fig.49C The following is a simplified schematic diagram of the light output of the LED lamp in the application embodiment, in which the dotted line is a simplified schematic diagram of the light. The outside of the first bracket 210, that is, the outer bracket 2102, emits light to the side wall. The side wall has a specific curvature and reflection effect. The light output of the outer bracket 2102 is reflected by at least one layer and then emitted from the outer edge area of ​​the LED lamp, so that the outer edge of the LED lamp has a better light output effect. The diffusion component 222 processes the light output of the second light strip 222 on the inner bracket 2101 and the light output of the first light strip 221 on the reinforcing rib 16 (for example, homogenization or diffusion, etc.), and then emits it from the central area of ​​the LED lamp. In this way, the edge and center of the LED lamp have approximately the same light output, and have similar brightness in visual effect, that is, almost all areas of the LED lamp have a light output effect, such as more than 90% of the area.

[0205] In some other embodiments, the area where the LED lamp has the light emitting effect may also be more than 50%, more than 60%, etc.

[0206] See also Figure 50 to Figure 53 As shown, in the second embodiment, the optoelectronic module 2 of the full-luminous LED lamp includes a second bracket 220 , a first light-emitting component 211 ″, a second light-emitting component 212 ″ and a strip lens 26 .

[0207] The second bracket 220 is fixed in the back panel 12. As an example, the second bracket 220 can be suspended in the back panel 12. A suspension part 25 can be provided between the second bracket 220 and the top of the back panel 12 and connected through the suspension part 25, that is, one end of the suspension part 25 is fixed to the back panel 12, and the other end is fixed to the second bracket 220. As an example, the suspension part 25 can be a hollow tubular structure to reduce the mass, and wiring can be arranged or not arranged in it according to needs. The height of the suspension part 25 determines the position of the second bracket 220. In order to make the upper half of the back panel 12 fully illuminated, the distance from the second bracket 220 to the top of the back panel 12 can be greater than the distance from the second bracket 220 to the bottom of the back panel 12. The second bracket 220 is roughly in the shape of a "U" character, and mounting positions are provided on both the upper and lower surfaces thereof to install the first light-emitting component 211" and the second light-emitting component 212".

[0208] See also FIG. 51A to FIG. 51D The first light-emitting component 211" and the second light-emitting component 212" are also LED light strips, wherein the first light-emitting component 211" is arranged at the upper end of the second bracket 220, and the first light-emitting component 211" emits light roughly along the positive direction of the z-axis to provide lighting for the top of the back panel and the upper side walls of the back panel 12. The number of the first light-emitting components 211" can be two, four or more. The second light-emitting component 212" is arranged at the lower end of the second bracket 220, and the second light-emitting component 212" emits light roughly along the reverse direction of the z-axis to provide lighting for the bottom surface of the back panel and the lower side edges of the back panel 12. The number of the first light-emitting components 211" can also be two, four or more. As an example, there may be four first light-emitting components 211", and four second light-emitting components 212", or there may be two first light-emitting components 211", and two second light-emitting components 212", or there may be two first light-emitting components 211", and four second light-emitting components 212". There is no specific limitation on the number of the first light-emitting components 211" and the second light-emitting components 212", as long as the light output can be uniform and the lighting effect can be improved. In one embodiment, there are two first light-emitting components 211", which are symmetrically arranged on both sides of the upper end of the second bracket 220, and there are four second light-emitting components 212", which are respectively arranged around the lower end of the second bracket 220. By arranging them in a ring on the four sides of the second bracket 220, the light output can be more uniform and the lighting effect can be improved.

[0209] See also Fig.51C and Fig.51DThe strip lens 26 and the diffusion component 222 both have corresponding cavities for accommodating the LED light strip, and the cavities respectively form a closed space with the upper and lower surfaces of the second bracket 220 to form a protective structure for the LED light strip. Furthermore, the cavities of the strip lens 26 and the diffusion component 222 are both designed with specific surface shapes to achieve different lighting effects, wherein the total length of the LED light strip is less than the total length of the cavity.

[0210] In addition, the second bracket 220 may also be in an "I"-shaped structure (not shown), and the upper and lower surfaces of the second bracket are also provided with mounting positions. The first light-emitting component 211" and the second light-emitting component 212" may be arranged in a straight line on the upper and lower sides of the second bracket 220, and also have a relatively uniform light-emitting effect. In some other embodiments, the second bracket 26 may also be other structures, such as a wavy shape, a rectangular surface, etc.

[0211] The optoelectronic module 2 in the above-mentioned full-luminous LED lamp adopts a suspension design, which is also simplified in structure and beautiful in shape, and can improve the aesthetics and lighting effect of the LED lamp. In one embodiment of the present application, one end of the suspension part 25 is fixed near the mounting hole 15 and is arranged in the lamp trough 12, that is, in the direction of light emission of the lamp, and is fixed by screws, glue, buckles / snap-fits, etc., and the other end is fixed on the surface of the second bracket 220, wherein the suspension part 25 and the second bracket 220 can be integrally formed, or they can be separately formed and then fixed to each other.

[0212] In another embodiment of the present application, the suspension part 25 can also be fixed through the mounting hole 15, that is, the suspension part 25 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 25 passes through the mounting hole 15, and the large end is stuck on the outside of the bottom surface 1, that is, in the opposite direction of the light emitting direction of the lamp, and can be fixed under the action of gravity without additional fixing (see Fig.53 ).

[0213] like FIG. 51A to FIG. 53 As shown, a strip lens 26 is provided above the first light-emitting component 211 ″. The strip lens 26 is strip-shaped and is used to guide the light emitted by the upper LED lamp to disperse toward both sides so as to more evenly illuminate the middle and surrounding areas of the support unit 1.

[0214] Among them, along the length direction of the vertical strip lens 26, that is, the radial direction, the cross-section of the strip lens 26 is a semicircular structure or an arc structure as a whole, and a light strip cavity 260 is arranged inside the strip lens 26. The cross-section of the light strip cavity 260 can be triangular, arc-shaped, or a semicircular shape parallel to the semicircular shape of the cross-section of the strip lens 26, etc., but not limited thereto, and can be set according to actual light output requirements. In the present application, the light strip cavity 260 has a smooth surface, but in other embodiments, it can also be an uneven surface, such as a frosted surface, a continuous concave-convex surface, a Fresnel lens surface, etc., to meet different light effects, such as diffuse reflection, etc. Specifically, when the light emitted by the first light-emitting component 211" is emitted from the light strip cavity 260 to the outside, refraction will occur. The luminous flux of any first light-emitting component 211" toward the middle of the back panel 12 will be smaller than the luminous flux toward the surrounding area of ​​the supporting unit 1. However, after the luminous flux of the two first light-emitting components 211" toward the middle of the back panel 12 is superimposed, it will tend to be consistent with the luminous flux of any first light-emitting component 211" toward the surrounding area of ​​the back panel 12, so that the entire LED lamp will not have dark areas, thereby improving the lighting effect. The length of the light strip cavity 260 in the strip lens 26 is more than 80% of the total length of the strip lens 26. The two ends of the strip lens 26 can be an integrally formed closed surface, or a split closed surface, or the light strip cavity 260 can completely penetrate the strip lens 26.

[0215] The strip lenses 26 may also be formed by arranging independent single lenses.

[0216] In a specific embodiment, the brightness of the light from the second light-emitting component 212" after passing through the diffusion component 222 is one-third to one-fifth, preferably one-quarter, of the brightness of the light from the first light-emitting component 211" after passing through the strip lens 26. 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, and the light is reflected and re-emitted through the back panel 12, which can effectively improve the lighting effect.

[0217] In a specific embodiment, the diffusion component 222 is in a "U"-shaped structure and is fixedly connected to the second bracket 220; the second light-emitting component 212" is located in the diffusion component 222, and the diffusion component 222 disperses and atomizes the light to achieve a better light-emitting effect.

[0218] See also Fig.46 and Fig.50 As shown, in a specific embodiment, the diffusion component 222 is located inside the back plate 12 or flush with the plane where the notch of the back plate 12 is located, so as to improve the aesthetic appearance of the LED lamp.

[0219] The LED light strips in the above embodiments of the present application may also be composed of LED filaments, LED lamp bead arrays, light bulbs and other forms but not limited to these.

[0220] In another embodiment of the present application, light source panels with different directions are further arranged to make the light emission directions of the optoelectronic module more diverse and uniform, further improve the light emission uniformity, and provide more installation space for installing the light-emitting components in the optoelectronic module through the arrangement of the light source panels. Fig.54 The XYZ rectangular coordinate system established in the definition is: the side located in the positive direction of the X axis is defined as the right side, and the side located in the negative direction of the X axis is defined as the left side; the side located in the positive direction of the Y axis is defined as the front side, and the side located in the negative direction of the Y axis is defined as the back side; the side located in the positive direction of the Z axis is defined as the top side, and the side located in the negative direction of the Z axis is defined as the bottom side.

[0221] Next, the LED lamp proposed in this application (hereinafter referred to as LED lamp) is described with reference to the accompanying drawings.

[0222] like Fig.54 and Fig.55 As shown, an LED lamp proposed in the present application includes: a supporting unit 1, a diffusion component 222 (or a light processing unit), a power module 13 and a photoelectric module 2; the lamp is fixed to a mounting surface, such as an indoor ceiling, by the supporting unit 1 to achieve indoor lighting; the diffusion component 222 is fixedly connected to the supporting unit 1 at both ends extending along the X-axis direction, that is, the length direction of the lamp, through the first end cover 3, and the illumination uniformity of the lamp is improved by the diffusion component 222, and at the same time, the curved surface of the diffusion component 222 is combined with the supporting unit 1, The light emitting direction of the lamp, that is, the positive direction of the Z axis forms a complete light emitting surface, which ensures visual integrity and enhances the external aesthetics of the lamp; the light source is powered by the power module 13; the optoelectronic module 2 is arranged between the supporting unit 1 and the diffusion component 222, providing a first light-emitting component 211" and a second light-emitting component 212", to expand the lighting range, wherein the diffusion component 222 is covered on 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.

[0223] like Fig.55 As shown, the support unit 1 specifically includes a base 11, which can be fixed to the installation surface by means of screws, buckles, embedding, etc. The base 11 can be set to an arc structure or a square structure according to actual needs.

[0224] like Fig.54 , Fig.55 and Fig.61As shown, in a specific embodiment, the base 11 is configured as a square structure, and the front and rear ends of the base 11 are connected with side walls extending upward, which can also be called first side walls 112'. The base 11 and the first side walls 112' at both ends can be configured as an integral structure, which is integrally formed through a stamping process. The production process is relatively simple and the structural strength is relatively high. It can also be configured as a split structure, which is easy to disassemble and convenient for staff and subsequent maintenance. At the same time, a back plate 12 is stacked on the base 11, and the back plate 12 is set to a wide-upper-narrow-lower structure. Specifically, the width of the upper end of the back plate 12 in the front-to-back direction is D1, the width of the lower end of the back plate 12 in the front-to-back direction is D2, and the width of the upper end between the first side walls 112' on both sides of the base 11 in the front-to-back direction is D3. D1 needs to be greater than or equal to D2. Preferably, D1 is greater than D2. To ensure that the back plate 12 can be placed in the support unit 1 more conveniently, D3 is greater than D2, D3 is slightly greater than or equal to D1, and the height of the base 11 in the upper and lower directions 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 fit tightly without generating gaps, light leakage, etc. In a specific embodiment, the back plate 12 can be set to a square structure or an arc structure with a support plate connected to the side.

[0225] like Fig.55 As shown, the back plate 12 is provided with an upward protrusion 123 at the central axis extending in the length direction, forming a receiving cavity with the base 11, the power module 13 is arranged inside the protrusion 123 and fixedly connected to the base 11, the base 11 is provided with an opening at the position corresponding to the power module 13, and the wiring board 133 is electrically connected to the external circuit from the opening. The power module 13 is built into the support unit 1 to achieve space reuse, which can effectively save space and reduce the overall height of the lamp. At the same time, there is no need to package the power module 13 and the support unit 1 separately, which reduces the packaging volume and reduces the cost.

[0226] like Fig.59 As shown, the protrusion 123 extends left and right along the length direction of the lamp. From the cross-section, the shape of the protrusion 123 is similar to a trapezoid, and its upper end surface is set as a relatively flat horizontal surface, which is convenient for installing the optoelectronic module 2 on the upper end surface of the protrusion 123, and its two side surfaces are set as inclined surfaces with a certain inclination angle, which can reflect the light emitted by the side light source of the optoelectronic module 2 to a certain extent, further enhance the light output at the side position of the lamp, reduce the dark area, avoid excessive concentration of light output, and enhance the uniformity of illumination.

[0227] like Fig.62 As shown, in another specific embodiment, the base 11 is configured as an arc-shaped structure with its arc-shaped opening facing upward. The base 11 is arc-shaped and warped to form a certain space. The power module 13 can be disposed in the space formed by the arc-shaped base 11 and the mounting surface. Outside the external supporting unit 1, the power module can be disposed without increasing the overall thickness of the lamp.

[0228] The base 11 is provided with an upward protrusion at the central axis extending along the length direction, and the power module 13 can also be arranged in the protrusion and fixed on the mounting surface. The power module 13 is built into the support unit 1, without adding extra height and volume to the lamp, while improving the aesthetics of the lamp. The protrusion has the same function as in the above embodiment, and its relatively flat upper surface can be used to fix the light source module, which will not be described in detail here.

[0229] like Fig.55 As shown, the power module 13 includes a connecting plate 131, which is fixed to the supporting unit 1 by means of screws, bonding, clamping or the like. A terminal block 133 is arranged on the connecting plate 131, and the terminal block 133 is connected to an external circuit by a wire. A first power supply 132 is arranged on the side of the terminal block 133, and the first power supply 132 is electrically connected to the terminal block 133.

[0230] like Fig.55 , Fig.58 , Fig.59 , Fig.60AAs shown, an optoelectronic module 2 is arranged on the back panel 12, and the optoelectronic module 2 includes a light source board 201. A groove 202 is arranged at the central axis of the light source board 201. The upper end surface of the light source board 201 is symmetrical on both sides with the groove 202 as the center. The surface of the groove 202 intersects with the plane where the upper end surface is located, and the angle between the two can be adjusted. In one embodiment of the present application, the two are roughly perpendicular; two groups of first light-emitting components 211" are arranged on the upper end surface. The symmetrical arrangement can effectively ensure the uniformity of the illumination of the front light, and each group of first light-emitting components 211" includes a first light-emitting component arranged on the light source board 201. A circuit board 2111', a plurality of first light-emitting bodies 2112' are arranged and extended left and right along the length direction on the first circuit board 2111', when the first light-emitting body 2112' is powered on, the first light-emitting body 2112' emits light that irradiates upward, and the number of the first light-emitting bodies 2112' can be adjusted according to the actual required light intensity, and the more the number of the first light-emitting bodies 2112' is, the greater the forward light intensity of the LED lamp is. In the present embodiment, at least one row of first light-emitting bodies 2112' (such as one row or two rows, etc.) is arranged on the first circuit boards 2111' on both sides. That is, the optoelectronic module 2 has light output in at least two directions. The base 11 includes a bottom surface 111, and the bottom surface 111 and the first side wall 112' (or the side wall) are combined with the second end cover 4 to form a accommodating cavity, and the optoelectronic module 2, the power module 13, and the back panel 12 are arranged in the accommodating cavity. The height of the diffusion component 222 is less than or equal to the height of the first side wall 112' along the positive direction of the Z axis to ensure the overall installation beauty of the lamp and prevent the diffusion component 222 from protruding from the supporting unit 1. When the diffusion component 222 protrudes from the supporting unit 1, it is easy to be touched (bumped) by external objects and damaged. The back panel 12 also includes a light emitting curved surface 121 and a connecting portion 122, wherein the light emitting curved surface 121 corresponds to the lateral light emitting of the diffusion component 222, and the lateral light emitting of the diffusion component 222 is emitted from the light emitting direction after light processing, wherein the light emitting curved surface 121 can have a reflection function, a transmission function, a refraction function, a diffusion function, etc., or has at least two or more light processing functions at the same time. When the lateral light emitting of the diffusion component 222 reaches the light emitting curved surface 121, a part of the light is directly reflected, and a 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 multiple times. Of course, the lateral light emitting of the diffusion component 222 can also be completely reflected from the light emitting surface 121 without reaching the supporting unit 1.The back panel 12 also has a coupling portion 122, which is coupled to the end of the first side wall 112', i.e., one end along the positive direction of the Z-axis, by a snap-fitting manner. If the coupling portion 122 is a bent structure, the end of the first side wall 112' has a matching bend, and fixation can be completed by pressing the coupling portion 122 onto the end of the first side wall 112'. Of course, in other methods, the bent joint can be formed by hot pressing for fixation, or it can be fixed by additional components, such as screws, fixing frames, etc.

[0231] like Fig.58 and Fig.59 As shown, second light-emitting components 212" are arranged on opposite sides of the outside of the groove 202. The bottom of the groove 202 is fixed to the protrusion of the back plate 12 by screws (or glue, welding, buckles, etc.), so that there is a certain height difference between the second light-emitting component 212" and the back plate 12, which effectively expands the irradiation range of the second light-emitting component 212", that is, to a certain extent, the irradiation range of the second light-emitting component 212". The second light-emitting component 212" includes a second circuit board 2121' arranged on the outer side wall of the groove 202. The second circuit board 2121' is arranged on the left and right sides extending along the long axis direction. A plurality of second light-emitting bodies 2122" are arranged. When the second light-emitting body 2122" is powered on, the second light-emitting body 2122" emits light irradiated in the side direction. The number of the second light-emitting bodies 2122" can be adjusted according to the actual required light intensity. The more the number of the second light-emitting bodies 2122", the greater the light intensity of the side direction of the lamp body. In this embodiment, a row of second light-emitting bodies 2122" is arranged on the second circuit boards 2121' on both sides.

[0232] 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 output of the optoelectronic module 2 can be arranged at different positions through multiple lamp beads, so that the light output angle covers a range of 180° along the light output direction based on the plane where the bottom surface 111 is located.

[0233] refer to Fig.60A , combined with Fig.60B and Fig.60C It can be seen that, through the light source board 201, that is, the light source board 201 has mounting surfaces at different angles for mounting the light emitters, the light emitters at different angles emit light, and together constitute the light output of the LED lamp. Compared with traditional LED lamps, the light output angle is larger and the light output is softer. With the bottom surface 111 as the reference plane, the light output angle of the LED lamp can be 180°, that is, the light output can irradiate all corners of the LED lamp along the light output direction, avoiding dark areas in the LED lamp.

[0234] refer to Fig.60B, simplify the light-emitting unit 21, the structure is shown in the figure, and multiple light-emitting bodies in different directions are arranged, so that the light-emitting range of the light-emitting unit 21 in any plane can reach a 180° fan-shaped range with the light-emitting unit 21 as the center, such as the range shown in a in the figure, that is, in the three-dimensional space, it is a hemispherical range with the light-emitting unit 21 as the center, see Fig.60D .

[0235] refer to Fig.60C That is, the light-emitting unit 21 is arranged by emitting light in different directions so that the light-emitting angles b1 and b2 of the light-emitting unit 21 to both sides along the perpendicular midline of the light-emitting unit 21 can reach the maximum angle of 90° defined by the perpendicular midline and the bottom surface 111, thereby avoiding the appearance of dark areas in the light-emitting direction of the LED lamp.

[0236] like Fig.54 , Fig.55 , Fig.64A As shown, a diffusion component 222 is arranged above the photoelectric module 2, and a storage cavity 2225 for storing the photoelectric module 2 is opened on the diffusion component 222. The diffusion component 222 is fixedly connected to the support unit 1, and the photoelectric module 2 is arranged between the diffusion component 222 and the support unit 1. The diffusion component 222 is made of a material with light transmission and light diffusion properties. Preferably, the diffusion component 222 can be made of, but not limited to, a PP (Polypropylene, polypropylene) diffusion plate. The diffusion component 222 made of a PP diffusion plate not only has a high light transmittance, but also has a good light diffusion effect, which can avoid the problem of glare. The diffusion component 222 can be selected into an arc or square structure according to the specific implementation effect, which can enhance the light diffusion effect and improve the aesthetics of the lamp.

[0237] like Fig.60A The figure shows a cross-sectional schematic diagram of an LED lamp in an embodiment of the present application along a direction perpendicular to the optoelectronic module.
