Description

Technical Field

[0001] The present invention relates to the technical field of LED lighting devices, and in particular to an LED power supply device and an LED lamp using the same. Background Art

[0002] LED lamps, which use light-emitting diodes as their light source, are widely adopted due to their energy-saving and long lifespan. Panel lights, among other LED lamps, are highly sought after for their thinness, large illumination area, and clean, compact light-emitting surface.

[0003] In the power supply design of LED panel lights, safety is often the top priority. Grounding can effectively protect the personal safety of users. When the phase line contacts the device casing due to some reason, dangerous voltage will be generated on the device casing. The resulting fault current will flow through the grounding wire and transmit the dangerous current to the earth, thereby playing a protective role.

[0004] In the prior art, a ground wire is provided on the power supply of the LED panel light. Figure 49A As shown, the ground wire 23 is fixed to the power supply by screws 22. When the user installs the LED panel light, the ground wire 9 in the environment will be connected to the ground wire 23 in the power supply, generally using a nut to achieve the safety effect of grounding the power supply.

[0005] However, in the prior art, in the process of achieving grounding, it is necessary to set screws 22 and grounding wires 23 on the power supply in advance, which not only increases the number of steps in the manufacturing process, but also increases the installation difficulty for users.

[0006] In summary, given the shortcomings and defects of existing LED panel lights, how to design a grounding solution for LED panel lights to reduce the number of steps in the manufacturing process, reduce the installation difficulty for users, and improve the efficiency and safety of assembly is a technical problem that urgently needs to be solved by technical personnel in this field.

The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the present invention.

[0079] It will be understood that while the terms first, second, etc. may be used herein to describe various elements or parameters in some instances, these elements or parameters should not be limited by these terms. These terms are merely used to distinguish one element or parameter from another. For example, a first inclined portion may be referred to as a second inclined portion, and similarly, a second inclined portion may be referred to as a first inclined portion without departing from the scope of the various described embodiments. A first inclined portion and a second inclined portion are both describing a single inclined portion, but unless the context clearly indicates otherwise, they are not the same inclined portion. The terms "or" and "and / or" as used herein are to be interpreted as inclusive, meaning any one or any combination. Thus, "A, B, or C" or "A, B, and / or C" means any of the following: A; B; C; A and B; A and C; B and C; A, B, and C. Exceptions to this definition occur only when a combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0080] 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 be present. Conversely, when an element is referred to as being “directly on” or “extending directly onto” another element, there are no intervening elements present. It will also be understood that when an element is referred to as being “connected” or “coupled” to another element, it may be directly connected or coupled to the other element, or there may be intervening elements present. Conversely, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present.

[0081] 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 figures. It will be understood that these terms are intended to encompass different device orientations other than the orientation depicted in the figures. In the present invention, the terms "perpendicular," "horizontal," and "parallel" are defined as including ±10% of the standard definition. For example, perpendicular generally refers to an angle of 90° relative to a reference line, but in the present invention, perpendicular refers to an angle within a range of 80° to 100°.

[0082] The terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the present invention.

It will also be understood that the terms used herein should be interpreted as having a meaning consistent with their meaning 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 herein.

[0084] Unless otherwise expressly stated, comparative quantitative terms such as "above" and "below" are intended to encompass equivalent concepts. For example, "above" may not only mean "greater than" in a mathematical sense, but may also mean "equal to."

[0085] In some embodiments, the present invention discloses an LED lamp that can be suspended or fixed to a ceiling or suspended ceiling. Depending on the application, the LED lamp disclosed in the present invention may also be referred to as a panel light, flat panel light, pendant light, recessed light, cove light, recessed light, or ceiling light.

[0086] See also Figure 1 , which is a schematic diagram of the three-dimensional structure of an LED lamp in one embodiment of the present invention. As shown in the figure, the LED lamp includes a base 1 and a power supply device 2, and the power supply device 2 is connected to the base 1.

[0087] In some examples, the power supply unit 2 is connected to the base 1 in a replaceable (detachable) manner, so that the power supply unit 2 can be replaced for the LED lamp.

[0088] In another embodiment, the power supply device 2 can also be connected to the base 1 in a non-detachable manner, that is, after the power supply device 2 is fixed to the base 1, it cannot be easily disassembled or needs to be destructively disassembled. During packaging and transportation, the base 1 and the power supply device 2 are packaged and transported together.

[0089] In another embodiment, the power supply device 2 can be configured to be quickly installed with the base 1. After installation, the power supply device 2 and the base 1 cannot be easily disassembled or need to be destructively disassembled. Therefore, when packaging and transporting, the power supply device 2 and the base 1 can be packaged and transported separately, saving packaging and transportation costs. When selling or using, the power supply device 2 and the base 1 can be quickly installed.

[0090] In one embodiment, the LED lamp further comprises a light source assembly, and the light source assembly is disposed on the base. Figure 2 , which is a schematic diagram of the three-dimensional structure of the light source assembly and the base in one embodiment of the present invention. As shown in the figure, the base 1 includes a base plate 10 and a side wall 11. The side wall 11 surrounds the base plate 10 (or the periphery) and forms a receiving groove 14 with the base plate 10. The receiving groove 14 can also be called an receiving space. The light source assembly 3 is further arranged on the base plate 10 and is located in the receiving groove 14. The light source assembly 3 may include a circuit board 30 and a light-emitting body 31. The circuit board 30 is attached (for example, directly attached or attached through an intermediate medium) to the base plate 10 so that the circuit board 30 dissipates heat through the base plate 10. The base plate 10 can be configured to be formed of metal or plastic material. The light-emitting body 31 can be an LED lamp bead, or other types of LED light-emitting monomers. The light-emitting body 31 can be arranged into multiple groups, each group can include one or more light-emitting bodies 31, and multiple groups of light-emitting bodies 31 are evenly distributed on the circuit board 30. Figure 2 In the example, eight groups of luminous elements 31 are provided, each group including two luminous elements 31. Those skilled in the art may provide any number of luminous elements 31 according to actual needs. Specifically, the luminous elements 31 are attached to one side of the circuit board 30, while the other side of the circuit board 30 is attached to the base plate 10.

[0091] In some embodiments, multiple groups of light-emitting bodies 31 can also be arranged on the circuit board 30 in a non-uniformly distributed manner, that is, a larger number of light-emitting bodies 31 can be set in a local area according to needs to form an area with a higher density of light-emitting bodies 31; a smaller number of light-emitting bodies 31 can be set in a local area to form an area with a lower density of light-emitting bodies 31; by configuring the light-emitting bodies 31 with different densities in different areas, the adjustment and design of the light-emitting effect can be achieved.

[0092] In some embodiments, the light source assembly 3 can be provided in multiple groups, each group being arranged in parallel on the bottom plate 10, and each group of light source assembly 3 can be connected via a wiring element 7. For example, the light source assembly 3 can be provided in 2 groups, 3 groups, 4 groups, 5 groups, or 6 groups, etc. Figure 2 In the example shown, the light source assemblies 3 are arranged into 6 groups.

[0093] Of course, in some other embodiments, the light source assembly 3 may be provided as only one group, and those skilled in the art may select any number of groups to be configured on the base plate 10 according to actual needs.

[0094] The light source assembly 3 is further electrically connected to the power supply device 2 via the wiring element 7. In some embodiments, the power supply device 2 can be disposed within the receiving groove 14 (i.e., the area / space of the receiving groove 14 for accommodating or arranging the light source assembly 3) to drive the light source assembly 3 to emit light via the wiring element 7. In some implementations, the power supply device 2 can also be disposed outside the receiving groove 14 (e.g., at the back of the receiving groove 14), such as Figure 2 As shown, a wiring opening 112 is provided on the side wall 11 , and the wiring element 7 passes through the wiring opening 112 to be electrically connected to the power supply device 2 .

[0095] In one embodiment, the LED lamp may further include a light processing unit for processing the light emitted by the light source assembly 3. The processing methods for the emitted light include but are not limited to diffusion, projection, refraction, reflection, diffraction, transmission, etc. Figure 2 In the illustrated embodiment, the light processing unit includes a lens 32 covered on the light emitting body 31 , and the lens 32 and the light emitting body 31 are configured in a one-to-one correspondence.

[0096] like Figure 2 As shown, the base 1 further includes a mounting portion 12, which is arranged along the edge of the side wall 11 and is substantially parallel to the bottom plate 10. The mounting portion 12 is used to fix at least part of the structure or components in the LED lamp. For example, Figure 1 As shown, the LED lamp further includes a suspension mechanism 6, which can be directly or indirectly fixed to the mounting portion 12 and is used to install the LED lamp in the lighting space. For example, the suspension mechanism 6 can be configured as a hook, a slide rail, a bracket, etc., and the LED lamp is installed in the installation area of ​​the lighting space via the suspension mechanism 6. For another example, the light processing unit of the LED lamp may include an optical component fixed to the mounting portion 12 to cover the receiving groove 14.

[0097] See also Figures 3 to 5 , Figure 3 It shows a schematic diagram of a partially disassembled structure of an LED lamp in one embodiment of the present invention. Figure 4 The present invention is shown in Figure 3 A partial enlarged view of the A region in the embodiment shown, Figure 5 The present invention is shown in Figure 1 Schematic diagram of II cross section under a viewing angle in the embodiment of the LED lamp shown. Figures 3 to 5As shown, the light processing unit may include an optical component 4, which is fixed on the mounting portion 12 and covers the receiving groove 14. The optical component 4 may be, for example, a diffusion plate, which is used to diffuse the light generated by the light source assembly 3 to increase the uniformity of the light and reduce the glare of the lamp. For example, the optical component 4 may be made of PC material or acrylic plate, which has a light diffusion function due to its own material properties; or the optical component 4 may also be made of a transparent material, such as glass or transparent plastic, and a diffusion layer is provided on its surface to give it a light diffusion function. Figures 3 to 5 In the illustrated embodiment, the LED lamp further includes a frame 5 , through which the optical component 4 is fixed on the mounting portion 12 .

[0098] In one embodiment, if Figures 3 to 5 As shown, the frame 5 is used to fix the optical component 4 to the mounting portion 12. The frame 5 includes a frame 50 and may further include a connector 51. The frame 50 is sleeved on the mounting portion 12 to clamp the optical component 4 on the mounting portion 12. Specifically, the optical component 4 covers the accommodating groove 14 and the edge of the optical component 4 is attached to the side of the mounting portion 12 facing the light source assembly 3. The frame 50 is sleeved on the mounting portion 12 and the optical component 4 to clamp the mounting portion 12 and the optical component 4, so that the optical component 4 is fixed. The connector 51 is used to connect two adjacent frames 50 to position multiple frames 50 around the mounting portion 12.

[0099] In one embodiment, the number of frames 50 and connectors 51 is consistent with the number of sides of the mounting portion 12, so that the connectors 51 connect multiple frames 50 end to end to form a frame 5 corresponding to the shape of the mounting portion. For example, the bottom plate 10 can be configured as a polygon, and the side walls 11 and the mounting portion 12 are also configured as an annular structure corresponding to the number of sides of the polygon, and the number of frames 50 and connectors 51 is consistent with the number of sides of the mounting portion 12. Figures 3 to 5 In the illustrated embodiment, the base plate 10 is configured as a quadrilateral, the sidewall 11 is configured as a quadrilateral ring structure around the base plate 10, the mounting portion 12 is configured as a quadrilateral ring structure around the edge of the sidewall 11, and the frame 5 has four frames 50 and four connectors 51, each connector 51 connects two adjacent frames 50 end to end, thereby forming a quadrilateral frame 5. It should be understood that the above shapes are only examples, and the base plate 10 can also be configured as a triangle, pentagon, hexagon, etc., or other irregular shapes, and the mounting portion 12 is configured as a ring structure with a corresponding number of sides. The frames 50 and connectors 51 are also configured as three, five, or six, respectively, to form a polygonal frame such as a triangle, pentagon, or hexagon. Inspired by the above embodiments, the base plate 10 can also be configured as a circle, and the mounting portion 12 is configured as a circular ring structure. In this case, the frame 5 can only include the frames 50, and the frames 50 are configured as a circular ring that fits the mounting portion 12.

[0100] See also Figure 6 and Figure 7 , respectively, are shown as the present invention Figure 5 The B area in the embodiment shown is a partial enlarged view under different embodiments, as shown in FIG. Figure 6 and Figure 7 As shown, the mounting portion 12 is raised on the side opposite to the light source assembly to form a bent fixing portion 120, and the frame 50 includes a clamping portion 500 and a bent portion 501. The clamping portion 500 has a clamping space adapted to fit the mounting portion 12. During the assembly process, after the optical component 4 is attached to the mounting portion 12, it can be relatively inserted into the clamping space of the clamping portion 500. The bent portion 501 is arranged to extend along the clamping portion 500 and is engaged with the bent fixing portion 120 to position the frame 50. Specifically, during assembly, after the optical component 4 and the mounting portion 12 are relatively inserted into the clamping portion 500, the bent portion 501 can be bent toward the bent fixing portion 120 along the pre-formed bending point 502 through a press bending process to engage with the bent fixing portion 120. In this way, the frame 50 can be clamped on the mounting portion 12 without the need for additional fixation, greatly reducing the defect rate or process complexity caused by the provision of fixing parts such as screws. Of course, the assembly process can also be described as after the optical component 4 and the mounting portion 12 are relatively matched, the clamping portion 500 is sleeved on the outside of the assembly formed by the optical component 4 and the mounting portion 12, and then the bending portion 501 is bent toward the bending fixing portion 120 along the pre-formed bending point 502 through a bending process to engage with the bending fixing portion 120.

[0101] To further increase the stability of the frame clamping, in one embodiment, a positioning protrusion 5000 is provided on the side of the clamping portion 500 facing the optical component 4. The positioning protrusion 5000 further clamps the optical component 4 more firmly in the clamping portion 500 to prevent the optical component 4 from shaking or falling off.

[0102] In one embodiment, if Figure 7 As shown, the end of the frame 50 near the optical member 4 (the end here can be understood as the end where the frame 50 contacts the optical member 4) has a certain slope. In other words, the end surface of the frame 50 near the optical member 4 is configured as a bevel. This slope or bevel can, to a certain extent, achieve a better connection between the frame 50 and the optical member 4, thereby enhancing the overall visual effect of the combination of the two.

[0103] In one embodiment, if Figure 4 As shown, the connector 51 includes a corner guard 510 and a guide portion 511. The corner guard 510 is set at an arc angle to prevent the lamp from being deformed or damaged when it falls or bumps. The number of the guide portions 511 is set to correspond to the number of the frame 50 connected to the connector 51. Figure 4For example, two guide parts 511 are provided, which are respectively located on the sides of the corner guard 510 facing the two frames 50, and the frame 50 is provided with a card slot 503 corresponding to the guide part 511 so that the guide part 511 can be inserted into the card slot 503 to connect the connector 51 to the frame 50. For example, the guide part 511 and the card slot 503 can be interference fit to prevent loosening. The guide part 511 and the card slot 503 can also be provided with a matching card structure, and the card structure of the two can be engaged to prevent loosening. Further, in the case of Figure 4 In the illustrated embodiment, the corner guard 510 further has a clamping space facing the mounting portion 12 , which allows the mounting portion 12 to enter so that the connector 51 can position the frame 50 around the mounting portion 12 .

[0104] Corresponding to Figures 1 to 7 Regarding the LED lamp described in any embodiment, the present invention further provides an assembly method of the LED lamp in some embodiments.

[0105] The assembly method of the LED lamp comprises the following steps: providing a base including a bottom plate, a side wall, and a mounting portion; covering the optical component on the base and fitting it to the mounting portion; sleeve a frame on one side of the mounting portion and the optical component so that the clamping portion of the frame clamps the mounting portion and the optical component; bending the bending portion toward the bending fixing portion of the mounting portion along the bending point of the frame by a press bending process; inserting a guide portion of a connector into the head end of the frame; sleeve another frame on the other side of the mounting portion and the optical component (the other side is adjacent to the one side), and inserting the tail end of the other frame into the other guide portion of the connector; bending the bending portion toward the bending fixing portion of the mounting portion along the bending point of the other frame by a press bending process; inserting a guide portion of the other connector into the head end of the other frame; and repeating this cycle until a ring structure surrounding the mounting portion is formed. Furthermore, the assembly method may also include the steps of fixing a power supply device to the mounting portion and fixing a suspension mechanism to the mounting portion.

[0106] See also Figure 8 to Figure 1 1, Figure 8 It is a schematic diagram of the three-dimensional structure of the LED lamp with the folding portion unfolded (not folded) in one embodiment of the present invention. Figure 9 The figure shows a schematic diagram of the three-dimensional structure of the LED lamp after the folding portion is folded in one embodiment of the present invention. Figure 10A The present invention is shown in Figure 8 A schematic diagram of a II-II cross section in an embodiment of the LED lamp is shown, Figure 11A The present invention is shown in Figure 10A A partial enlarged view of region C in the illustrated embodiment.

[0107] like Figure 8 to Figure 1The basic structure of the LED lamp provided in the embodiment shown in 1 is Figures 1 to 7 The LED lamps provided in any embodiment are similar, except that the LED lamps no longer have a frame, and the base 1 further includes a folding portion 13 on the basis of including the bottom plate 10, the side wall 11, and the mounting portion 12. In one example, the number of the folding portions 13 is consistent with the number of sides of the mounting portion 12, for example Figure 8 to Figure 1 As shown in FIG1 , the mounting portion 12 is configured as a quadrilateral annular structure, and a folding portion 13 is provided on each side of the mounting portion 12, that is, four folding portions are provided, and the folding portions 13 are folded in the direction toward the optical component 4 (in the direction indicated by the dotted arrow in FIG11 ) to fix the optical component 4 (as shown in the figure). Furthermore, in order to prevent the folding portions 13 from overlapping, the two ends of the folding portion 13 can be configured as bevels (for example, the folding portion 13 is trapezoidal) so that when the folding portion 13 is folded to fit the optical component 4, the bevels of the two adjacent folding portions 13 are spliced ​​together, further making the light-transmitting surface formed by the optical component 4 a quadrilateral corresponding to the shape of the base plate 10 (as shown in FIG11 ). Figure 9 As shown), the light output effect is guaranteed.

[0108] In other examples, the number of folding portions 13 may also be inconsistent with the number of sides of the mounting portion 12. For example, in an example in which the mounting portion 12 is set as a circular ring structure, it can be set to any number of folding portions 13 formed on the edge of the mounting portion 12.

[0109] In one embodiment, if Figure 8 to Figure 1 1, the mounting portion 12 protrudes toward the bottom plate 10 to form a mounting groove 121. The mounting groove 121 is used to allow a fixing member to enter and pass through to fix the structure or component in the LED lamp. For example, the fixing member is a screw, which enters and passes through the mounting groove 121 to fix the power supply device 2 and / or the suspension mechanism 6. In this way, the fixing member is built into the LED lamp without affecting the appearance.

[0110] Corresponding to Figure 8 to Figure 1 In some embodiments of the LED lamp described in any one of the embodiments, the present invention further provides a method for assembling the LED lamp, comprising the following steps: providing a base comprising a bottom plate, side walls, a mounting portion, and a folding portion; covering the optical component on the base and attaching it to the mounting portion; and folding the folding portion toward the optical component to attach it to the optical component. Prior to covering the optical component on the base, the method may further include inserting a fixing member into a mounting groove on the mounting portion to secure the power supply device and / or the suspension mechanism.

[0111] Figure 10B The present invention is shown in Figure 8 A schematic diagram of a II-II cross section of the LED lamp in another embodiment is shown. Figure 11B The present invention is shown in Figure 10B A partial enlarged view of region C in the illustrated embodiment. Figure 10B and Figure 10A The difference lies in whether the edge of the optical component 4 is an inclined surface, such as Figure 10A The middle folding portion 13 is in contact with the inclined surface, and can be bent at a small angle to fix the optical component 4 .

[0112] Given that the size of the power supply device in the related art is usually difficult to adjust, the width of the mounting portion formed on the edge of the side wall needs to be wider to provide sufficient installation space for the power supply device, further resulting in a wider blocking area on the light-emitting surface, affecting the light-emitting effect and also affecting the overall visual effect of the product. In some embodiments provided by the present invention, the width of the installation space of the power supply device is increased by setting the side wall of the base to have at least two inclined portions, so that the blocking area can be extremely narrowed, the proportion of the light-emitting surface and the light-emitting effect can be improved, and at the same time, the inclined portion is provided so that the mounting portion formed on the edge of the side wall has a smooth transition with the light-emitting surface, which is different from the traditional design in which the edge of the mounting portion and the light-emitting surface form an obvious step structure, and the overall surface shape of the product is more complete. The subsequent embodiments are explained by taking the setting of two inclined portions on the side wall as an example, but it should not be understood that the following example is a limitation on the number of inclined portions.

[0113] The light emitting surface refers to the light emitting surface of the lamp. Figure 1 to Figure 1 1 as an example, the light generated by the light source assembly 3 is projected out through the optical component 4, so that the optical component 4 forms the light-emitting surface of the lamp. Since the edge of the optical component 4 is fixed to the mounting portion 12, the portion where the optical component 4 and the mounting portion 12 are combined is usually not light-transmissive. Therefore, a fixing mechanism is usually provided to fix the optical component 4 to the mounting portion 12, and the fixing mechanism can also block the non-light-emitting area on the optical component 4 to form a clearly defined blocking area with the optical component 4. Figures 1 to 7 For example, the embodiment shown in the figure is used as a fixing mechanism, and the blocking area corresponds to the frame 50 located on the light-emitting surface of the optical component 4. The width of the blocking area corresponds to Figure 6 and Figure 7 The side width d1 of the frame 50 is shown in FIG. Figure 8 to Figure 1 1 as an example, the fixing mechanism corresponds to the folding portion 13, the shielding area corresponds to the portion of the folding portion 13 that is folded and attached to the optical component 4, and the width of the shielding area corresponds to the side width d2 of the folding portion 13 shown in FIG. 11.

[0114] In one embodiment, if Figure 2As shown, the sidewall 11 of the base 1 includes a first inclined portion 110 and a second inclined portion 111 (the first inclined portion 110 and the second inclined portion 111 are arranged in a conforming manner) meaning that the second inclined portion 111 is connected to the first inclined portion 110. As shown in FIG11 , the first inclined portion 110 is connected to the edge of the base plate 10 and is inclined relative to the base plate 10. The first inclined portion 110 forms an angle α with respect to the base plate 10. The second inclined portion 111 is connected to the first inclined portion 110 and has a different inclination angle relative to the base plate 10. The angle of the second inclined portion 111 with respect to the base plate 10 is equal to the angle β shown in FIG11 . In one embodiment, the inclination angle of the second inclined portion 111 with respect to the base plate 10 is greater than the inclination angle of the first inclined portion 110 with respect to the base plate 10, i.e., the angle β is greater than the angle α. It should be understood that this embodiment is described using the diagram shown in FIG11 as an example, and the sidewall 11 of the LED lamp provided in any embodiment of the present invention may be configured in this or other structures.

[0115] Among them, the first inclined portion 110, the second inclined portion 111, and the mounting portion 12 form a configuration space outside the accommodating groove 14, and the width S of the configuration space is composed of the projection width s1 of the first inclined portion 110 and the second inclined portion 111 in the direction of the base plate 10 and the projection width s2 of the mounting portion 12 in the direction of the base plate 10. Compared with the side wall with only a single inclined portion, the provision of two inclined portions (110, 111) in this embodiment can increase the configuration width that the side wall can provide, greatly reducing the width requirement for the mounting portion 12, and further greatly reducing the width of the shielding area on the optical component 4, that is, the side width of the fixing mechanism on the light-emitting surface side of the optical component 4 is reduced. For example, Figure 6 and Figure 7 The side width d1 of the frame 50 as the frame of the fixing mechanism and the side width d2 of the folded portion 13 as the fixing mechanism in FIG. 11 can be set to be smaller.

[0116] In one embodiment, the width of the shielding area can be controlled to be less than 15 mm. Further, it can be controlled to be less than 12 mm. Figures 1 to 7 Taking the embodiment shown as an example, that is, the side width d1 of the frame 50 of the frame 5 can be controlled to be less than 15 mm. Figure 8 to Figure 1 1 as an example, that is, the side width d2 of the folded portion 13 can be controlled to be less than 15 mm. Figures 1 to 7 The side width d1 described in or Figure 8 to Figure 1 The side width d2 shown in FIG1 can be controlled to be less than 12 mm. It should be understood that the widths given in this embodiment are merely examples, and those skilled in the art can adjust the angles of the two inclined portions (110, 111) according to actual needs to further increase or decrease the configuration width provided by the sidewall, thereby further decreasing or increasing the width of the shielding area.

[0117] In one embodiment, to avoid forming a dark area on the sidewall, the inclination angle α of the first inclined portion 110 relative to the bottom plate 10 can be set to any angle between approximately 95° and 175°, and preferably set to any value between 140° and 150°.

[0118] Preferably, the optimal setting is any angle between about 142° and 146°. Furthermore, in an embodiment where the light source assemblies are arranged in multiple groups, the distance between a light source assembly close to a side wall and the side wall is smaller than the distance between the light source assembly and an adjacent light source assembly.

[0119] In one embodiment, to maximize the use of the configuration space, one side of the power supply device 2 is aligned with the side wall 11. For example, one side of the power supply device 2 is aligned with the connection between the first inclined portion 110 and the second inclined portion 111 on the side wall 11. Furthermore, to ensure a better fit between the power supply device 2 and the side wall 11, in one embodiment, at least the side of the power supply device 2 aligned with the side wall 11 is configured as a curved edge, and the connection between the first inclined portion 110 and the second inclined portion 111 forms a transition region adapted to the curved edge, so that the curved edge of the power supply device 2 is aligned with the transition region.

[0120] In one embodiment, as shown in FIG11 , the power supply device 2 is fixed to the base via a power box 20, which can protect and secure the power supply device 2. For example, the power box 20 is secured to the mounting portion 12 (as shown in FIG11 , a screw enters and passes through the mounting slot 121 to tighten the power box 20) so that the power supply device 2 is located within the configuration space formed outside the accommodating slot 14. The power supply device 2 may include a circuit assembly 21, which may include a power circuit board, as well as a plurality of electronic components and wiring components. The plurality of electronic components may be disposed on a power circuit board corresponding to the power supply device 2, or some of the electronic components may be disposed on a circuit board corresponding to the light source assembly, so as to share the same circuit board with the light source assembly.

[0121] Due to the height limitations of the power supply unit, the LED lamps provided in related art are relatively tall, resulting in high costs for packaging and shipping. To address this, in some embodiments of the present invention, the power supply unit protrudes from the base plate when positioned within the configuration space, allowing two LED lamps to overlap vertically when placed against the base plate. The vertical direction refers to the height, or thickness, of the LED lamps; that is, the power supply unit protrudes from the base plate in the thickness direction.

[0122] It should be noted that in order to reduce the height and width of the LED lamp, in embodiments in which a power box is provided, the surface of the power supply device close to the power box is affixed to the corresponding inner wall of the power box. Taking Figure 11 as an example, the power box 20 is configured as a generally L-shaped shell adapted to the configuration space, and the power supply device 2 is configured to be generally rectangular and is located within the power box 20 in a manner affixed to the two inner walls of the power box 20. Therefore, within the allowable error range, the dimensional information of the power supply device relative to the base plate mentioned in some embodiments of the present invention in which a power box is provided can be understood as the dimensional information of the power box relative to the base plate, and can be directly obtained by measuring the dimensional information of the power box relative to the base plate.

[0123] See also Figure 12 and Figure 13 Combined with Figure 11, Figure 12 It shows a schematic diagram of two LED lamps placed on a base plate in one embodiment of the present invention. Figure 13 The present invention is shown in Figure 12 FIG11 is a partial enlarged view of the D region in the embodiment shown, and shows the height h of the power supply device 2 protruding from the bottom plate 10, that is, there is a height difference h between the bottom plate 10 and the power supply device 2. Figure 12 and Figure 13 As shown, the distance between the surface of the bottom plate 10 of the first LED lamp T1 and the second LED lamp T2 facing away from the optical component 4 and the surface of the optical component 4 facing away from the bottom plate 10 is p, which can be called the main body height of the LED lamp.

[0124] When the first LED lamp T1 and the second LED lamp T2 are placed on the bottom plate, the two have an overlapping area M in the vertical direction. The overlapping area M is the area formed by the height difference between the bottom plate 10 and the power supply device 2. Figure 13 The area corresponding to the height h. Specifically, when the base plate 10 of the first LED lamp T1 is attached to the base plate 10 of the second LED lamp T2, the base plate 10 of the first LED lamp T1 will be located in the area corresponding to the height difference h between the base plate 10 of the second LED lamp T2 and the power supply device 2, while the base plate 10 of the second LED lamp T2 is located in the area corresponding to the height difference h between the base plate 10 of the first LED lamp T1 and the power supply device 2. Of course, in some embodiments, the power supply device 2 can also be configured not to protrude from the base plate 10 (not shown). For example, the power supply device 2 is flush with the base plate 10, that is, the height difference h between the power supply device 2 and the base plate 10 as shown in Figure 11 does not exist, that is, the height difference is zero, and the height of the power supply device 2 just reaches the plane where the base plate 10 is located.

[0125] In order to ensure that the two LED lamps can better fit and maximize the use of the overlapping area, in one embodiment, as shown in FIG11 , a side wall 11 of the power box 20 for accommodating the power supply device 2, which is close to the base plate 10, is tilted relative to the base plate 10, and the angle γ of the tilt setting is consistent with the tilt angle α of the first tilted portion 110. For example, the angle γ of the tilt setting is equal to the tilt angle α of the first tilted portion 110. When the angle γ and the tilt angle α are consistent, when the two LED lamps are stacked, the first tilted portion 110 of one LED lamp and the tilted side wall 11 of the power box 20 of another LED lamp, which is close to the base plate 10, can fit perfectly (be parallel), thereby improving the stability of the stacked arrangement.

[0126] In another embodiment of the present invention, the inclination angle γ is greater than the inclination angle α of the first inclined portion 110. When the inclination angle γ is greater than the inclination angle α of the first inclined portion 110, that is, the space where the inclination angle γ is located, the angle space formed by the bottom plate 10 and the side wall 11 of the power box 20 close to the bottom plate 10 can completely accommodate the angle formed by the bottom plate 10 and the first inclined portion 110, thereby ensuring that Figure 12 When the LED lamps are stacked, the first inclined portion 110 does not interfere with the power box 20. Figure 12 The packaging and transportation are carried out in the manner shown. Thus, in the vertical direction, compared with the packaging and transportation of a single LED lamp, the height of the two LED lamps can be reduced (the height h of the two power supply devices 2 protruding from the bottom plate 10 is reduced, that is, the height is reduced by 2×h), saving packaging and transportation costs. Figure 13 As shown in the figure, when two LED lamps are placed on the bottom plate 10, the height h of the power supply device 2 of the first LED lamp T1 protruding from the bottom plate 10 overlaps with the height of the bottom plate 10 of the second LED lamp T2 from the optical component 4, and the height h of the power supply device 2 of the second LED lamp T2 protruding from the bottom plate 10 overlaps with the height of the bottom plate 10 of the first LED lamp T1 from the optical component 4. Therefore, the height of the power supply device 2 protruding from the bottom plate 10 does not occupy the total height (or total thickness) of the two LED lamps. Figure 12 Placed as shown, the total height is the sum of the main body heights of the two LED lamps, i.e., 2 × p. In this embodiment, the main body height refers to the distance from the surface of the base plate 10 facing away from the optical component 4 to the surface of the optical component 4 facing away from the base plate 10. The height of the power supply unit, also known as its thickness, can be understood as the overall height or thickness of the LED lamp, corresponding to the distance between the side of the power supply unit located toward the base plate and the optical component. In embodiments where the power supply unit is housed in a power box, this also corresponds to the distance between the side of the power box located toward the base plate and the optical component.

[0127] In one embodiment, the height of the bottom plate 10 from the optical component 4 can be lowered so that the power supply device 2 protrudes from the bottom plate 10. In one example, the power supply device is set in the configuration space formed by the aforementioned first inclined portion, the second inclined portion, and the mounting portion, so that the height of the power supply device or the overall height of the LED lamp can be controlled below 40 mm, and further, can be controlled below 35 mm. Lowering the height of the bottom plate 10 from the optical component 4 while meeting the light output requirements can control the distance between the bottom plate 10 and the optical component 4 to below 35 mm, and further, the distance between the bottom plate 10 and the optical component 4 to below 30 mm. For example, the height of the power supply device or the overall height of the LED lamp can be set to 35 mm, and the height of the bottom plate 10 can be set to 30 mm. In this way, compared with packaging and transporting a single LED lamp separately, Figure 12 and Figure 13 The packaging and transportation method shown can reduce the height by 10mm.

[0128] In one embodiment, the overall height of the LED lamp is less than or equal to 6 / 5 of the height of the power supply device, that is, the height of the power supply device protruding from the bottom plate 10 is less than or equal to 1 / 5 of the main body height p of the LED lamp. Figure 12 and Figure 13 The packaging and transportation method shown can reduce the total height of the two LED lamps by at least 1 / 6, that is, the reduced height is greater than or equal to 1 / 6 of the total height of the two lamps.

[0129] In some embodiments, the height of the power supply protruding from the bottom plate 10 is less than or equal to 1 / 15 of the height of the bottom plate, for example, less than or equal to 2 mm.

[0130] Corresponding to Figures 8 to 13 The present invention may also provide a packaging method for LED lamps in some embodiments, including the following steps: providing an LED lamp, the LED lamp having the structure and placement of the present invention. Figure 8 to Figure 1 1. An LED lamp having the structure of any embodiment; placing another LED lamp with its bottom plate bonded to the bottom plate of the first LED lamp; and packaging the two LED lamps. In some embodiments, before bonding the second LED lamp to the first LED lamp, a membrane may be placed on the bottom plate of the first LED lamp. The membrane may be, for example, a film made of foam or other soft material. It should be understood that bonding in any embodiment of the present invention may refer to bonding directly or through a medium, and does not necessarily require bonding by direct contact.

[0131] See also Figure 14 and 15Schematic diagram of an LED lamp in another embodiment of the present invention and its corresponding exploded view. Except for the optical component 4 and the frame 5 which are obviously different from the above embodiment, other components are basically the same and will not be described in detail below.

[0132] Combined with the same 14 and Figure 15 As shown, in this embodiment, the optical component 4 is composed of a first light processing unit 40, at least two second light processing units 41 connected to the first light processing unit 40, and a third light processing unit 42 corresponding to the second light processing unit 41, wherein the first light processing unit 40 is a curved surface, has light transmission and light diffusion functions, is made of PC, resin, acrylic plate or latex, and protrudes toward the bottom plate 10. There are two second light processing units 41, one on each side of the first light processing unit 40. The second light processing units 41 have micro-optical structures on their surfaces. These micro-optical structures can be patterned arrays, such as projections or depressions arranged in a certain shape. These projections and depressions disrupt some of the light emitted from the light source assembly 3. This means that the light emitted from the light source assembly 3 undergoes at least one optical processing function, such as transmission, refraction, and reflection, through the micro-optical structures. Light emitted from the same area is dispersed in different directions, thereby homogenizing the light. The second light processing units 41 are made of PC, resin, acrylic sheet, or latex, and have micro-optical structures integrally formed on their surfaces through embossing, rubbing, injection molding, or molding. The second light processing units 41 diffuse the light emitted from the light source assembly 3 after processing, thus functioning as light diffusion units. The second light processing units 41 and the first light processing unit 40 can be integrally formed from the same material, or they can be independently formed from the same material and then assembled, such as from milky white PC, either integrally or separately. Of course, in other embodiments, it can also be formed of different materials in one piece or in separate pieces.

[0133] In one embodiment of the present invention, the micro-optical structure of the second light processing unit 41 is disposed on the surface of the second light processing unit 41 facing away from the light source assembly 3. A third light processing unit 42 is disposed on the surface of the second light processing unit 41 facing the light-emitting element 3. The third light processing unit 42 corresponds to the second light processing unit 41 and is directly or indirectly attached to the second light processing unit 41. The third light processing unit 42 is a thin film with a light diffusion function that can diffuse light emitted from the light source assembly 3, further diffusing the light that passes through the third light processing unit 42 and reaches the second light processing unit 41. The third light processing unit 42 can be made of a material such as polyester film or PET. In some embodiments, the third light processing unit 42 and the second light processing unit 41 are bonded together using transparent glue.

[0134] See also Figure 16 、 17 and 18, Figure 16 and 17 These are two implementations of the frame 5 in one embodiment of the present invention. Figure 18 FIG2 is a transverse cross-section of a frame 50 and an enlarged view thereof according to an embodiment of the present invention. Figure 16 In one embodiment of the present invention, the frame 5 includes a frame 50 and an auxiliary support rod 52, wherein the number of the frame 50 is 4, and two opposite frames 50 are connected as a whole by the auxiliary support rod 52. Figure 16 After the parts are formed separately as shown, they can be connected together. Figure 17 The two opposing frames shown are integrally formed with the auxiliary support rod 52, and a portion of the optical component 4 is fixed by the auxiliary support member 52. For example, in one embodiment of the present invention, the two long sides of the first optical processing unit 40, the second optical processing unit 41 and the third optical processing unit 42 are fixed to the auxiliary support rod 52 near the long side of the first optical processing unit 40, thereby improving the overall fixing strength of the optical component 4.

[0135] In one embodiment of the present invention, the optical component 4 is also fixed to the mounting portion 12 by the frame 5. However, compared with the aforementioned frame 5, the connecting piece 51 is eliminated, and fixation is achieved by the cooperation between the unique structure between the frame 50 and the mounting portion 12. The two ends of the frame 50 are trapezoidal structures, and the angle of the hypotenuse of the trapezoid is 45°. The frames 50 are perpendicular to each other after the hypotenuses of the trapezoid cooperate with each other.

[0136] Please refer to Figure 18 and Figure 19 , Figure 18 1 is a schematic cross-sectional view of a frame along the horizontal direction and an enlarged view thereof in one embodiment of the present invention. Figure 19 FIG. 1 is a schematic diagram of the combination of the frame 50 and the base 1 (mounting portion 12) in one embodiment of the present invention. Figure 18 As mentioned above, the frame 50 includes a first step 53, a fixing groove 54 and a supporting surface 55, all of which are integrally formed on the frame 50. Figure 19 As shown, the base 1 includes a mounting portion 12, which includes a limiting portion 122 away from the bottom plate 10, and a receiving portion 123 located outside the limiting portion 122. At least a portion of the first step 53 and the fixing groove 54 are provided on the receiving portion 123. The fixing groove 54 can be provided with adhesive to achieve fixation with the receiving portion 123. In some embodiments, the inner wall of the fixing groove 54 is provided with a threaded or raised structure. A screw or rivet penetrating the receiving portion 123 penetrates into the fixing groove 54 and engages with the threaded or raised structure to achieve fixation of the frame 5 and the base 1. The limiting portion 122 and the supporting surface 55 clamp the optical component 4 and fix it. Figure 20 , is a schematic diagram of a micro-optical structure 410 in one embodiment of the present invention, which is magnified in a certain proportion for easier understanding. Figure 20As shown, the micro-optical structure 410 is a patterned structure provided on the surface of the second optical processing unit 41 away from the light-emitting element 3, such as a triangular array pattern; of course, in other embodiments, it can also be a circle, rectangle, etc., but not limited thereto. Of course, it can also be an array of micro-protrusions in the light-emitting direction. In other embodiments, it can also be a grating array provided on the second optical processing unit 41. The micro-optical structure 410 makes the surface of the second optical processing unit 41 rough, and the light passing through the second optical processing unit 41 is irregularly emitted and reflected in various directions by the micro-optical structure 410, that is, the second optical processing unit 41 with a rough surface has inconsistent emission directions at various points on its surface. Even if the incident light is parallel or focused, the emitted or reflected light is diffused in different directions, that is, there are no obvious bright spots and dark spots on its light-emitting surface, the light emission is uniform, and the glare is small.

[0137] See also Figure 21 This is a schematic diagram of an exploded view of an LED lamp in another embodiment of the present invention. Compared with the aforementioned LED lamp with the second light processing unit 41, it does not have the third light processing unit 42. The second light processing unit 41 is an anti-glare laminate, the material of which is different from that of the first light processing unit 40, and has scattering and uniform light effects.

[0138] In this embodiment, the combination of the first light processing unit 40, the second light processing unit 41, and the third light processing unit 42 can achieve a UGR value of less than or equal to 19. The UGR value is the unified glare value, which can be used to evaluate lighting quality. The calculation method of the unified glare value is as follows:

[0139]

[0140] Among them, L b is the background brightness, in cd / m 2 ;

[0141] ω is the solid angle formed by the luminous part of each lamp to the observer's eyes, the unit is sr;

[0142] L α is the brightness of the lamp in the direction of the observer's eyes cd / m 2 ;

[0143] P is the position index of each individual luminaire;

[0144] In the present invention, the light intensity, the shape of the light emitting surface, the thickness of the lamp are controlled to control L b ,ω,L α, P, thereby controlling the uniform glare value (i.e., UGR value) of the lamp to ensure the light quality and user comfort of the lamp. The solid angle is the projected area of ​​any object onto a unit sphere constructed with the observation point (i.e., the human eye) as the center of the sphere, which is the solid angle of the object relative to the observation point.

[0145] In some embodiments of the present invention, there are at least two (or more) types of light-emitting bodies 31 (i.e., LED lamp beads or LED chips of the light-emitting bodies 31) provided in the light source assembly 3 of the LED lamp. The light-emitting bodies 31 can be composed of LED lamp beads or LED chips, and a plurality of light-emitting bodies 31 are arranged in an array on the circuit board 30 to form the light source assembly 3. In one embodiment of the present invention, there are two types of light-emitting bodies 31 (i.e., LED lamp beads or LED chips of the light-emitting bodies 31). For ease of description, one of the light-emitting bodies is referred to as light-emitting body 31a, and the other light-emitting body is referred to as light-emitting body 31b. Light-emitting body 31a and light-emitting body 31b are set to have different color temperatures or different light output intensities, or light-emitting body 31a and light-emitting body 31b have different color temperatures and light output intensities at the same time. In one embodiment of the present invention, light-emitting bodies of different color temperatures and / or different light intensities are arranged in a row, as follows Figure 22 As shown, on the bottom plate 10 of the LED lamp, multiple rows of light-emitting arrays are arranged in a horizontal direction, each of which is composed of a plurality of light-emitting bodies 31a and a plurality of light-emitting bodies 31b. Figure 22 As shown, the same row is composed of the same type of light-emitting bodies. For example, the first row is composed of multiple light-emitting bodies 31a, and the other row adjacent to the first row is composed of multiple light-emitting bodies 31b, and so on. That is, each row of the light-emitting body array is composed of the same light-emitting body, but the types of light-emitting bodies between adjacent rows are different or at least two.

[0146] See also Figure 23 As shown in FIG. 1 , a light-emitting device arrangement method in another embodiment of the present invention is shown. As shown in the figure, multiple light-emitting devices 31a and multiple light-emitting devices 31b are arranged longitudinally to form multiple light-emitting device arrays along the longitudinal direction. Each light-emitting device array is composed of the same type of light-emitting devices, but the light-emitting devices of two adjacent light-emitting device arrays are of different types or at least two types. Figure 22 and 23 In the LED lamp shown, light-emitting arrays of different light-emitting types are arranged at intervals, that is, a light-emitting array of a row or column composed of one light-emitting element must have a light-emitting array of a row or column composed of another light-emitting element in the adjacent row or column.

[0147] Of course, in other embodiments of the present invention, the rows or columns composed of different light-emitting bodies can also be arranged in a cycle with multiple rows or columns spaced apart.

[0148] Reference Figure 22and Figure 23 In the embodiment shown in , a light emitting array composed of different types of light emitting elements arranged in rows or columns can be arranged in an intermittent manner to produce a unique light effect on the light emitting surface, such as a light emitting pattern formed by a specific area having a higher or lower brightness than a specific area. Figure 24 , a light overlapping area 310 is formed between the light emitting body 31a and the light emitting body 31a, and a light overlapping area 311 is formed between the light emitting body 31a and the light emitting body 31b. The array is distributed in 2*2, with two light emitting bodies 31a in each column and two light emitting bodies 31b in each column. The light overlapping area 312 at the center position and the light overlapping area 313 are formed between the light emitting body 31b and the light overlapping area 310, the light overlapping area 311, the light overlapping area 312 and the light overlapping area 313 have different light intensities or color temperatures due to the differences between the adjacent light emitting bodies. The light intensity and color temperature of the light overlapping areas can be controlled by setting different adjacent light emitting bodies, thereby forming a specific patterned light on the overall light emitting surface, such as Figure 24 As shown, the light emission effects of each row or column are different, thereby forming a specific patterned light emission.

[0149] See also Figure 25 , is another arrangement of multiple light-emitting bodies in one embodiment of the present invention. Figure 24 As shown, there are two types of light-emitting bodies in the LED lamp, namely light-emitting body 31a and light-emitting body 31b, wherein light-emitting body 31a and light-emitting body 31b have different color temperatures and / or light output intensities, and light-emitting body 31a and light-emitting body 31b are staggered, that is, the light-emitting body adjacent to light-emitting body 31a must be a light-emitting body 31b different from it, that is, in each row or column, light-emitting body 31a and light-emitting body 31b are arranged adjacent to each other. Overall, light-emitting body 31a and light-emitting body 31b are doped with each other on the base plate 10 and are evenly doped.

[0150] See also Figure 26 ,and Figure 27 ,for Figure 25 The embodiment in the embodiment is described from another perspective, as shown in FIG. Figure 26 and 27 As shown, in the horizontal row direction or the vertical column direction, the light-emitting bodies 31a and the light-emitting bodies 31b are distributed in a wavy curve, or it can be said that they are distributed in the form of a cosine (sine) function image, or it can be said that they are distributed in an S-shaped cycle. The light-emitting bodies are distributed in such a way that the light intensity and / or color temperature of the light overlapping area between each adjacent light-emitting body are basically the same.

[0151] See also Figure 28, is a schematic diagram of the light overlapping area in one embodiment of the present invention. As shown in the figure, since the light-emitting bodies 31a and the light-emitting bodies 31b are staggered with each other when setting the light-emitting bodies, the solid light overlapping area only has the light overlapping area 311 and the light overlapping area 312, and the light overlapping area 311 and the light overlapping area 312 are evenly distributed, so that the overall light output of the LED lamp is uniform, without obvious bright spots and dark spots.

[0152] Continue reading Figure 28 In one embodiment of the present invention, in the longitudinal direction or the column direction, the longitudinal spacing between adjacent different light-emitting bodies 31a and light-emitting bodies 31b is L1, 10mm≤L1≤30mm;

[0153] In the longitudinal direction or the column direction, the longitudinal spacing between adjacent identical luminous bodies 31a and luminous bodies 31a (luminous bodies 31b and luminous bodies 31b) is L2, 20mm≤L2≤40mm;

[0154] In the horizontal direction or row direction, the horizontal spacing between adjacent different light-emitting bodies 31a and light-emitting bodies 31b is L3, 10mm≤L3≤30mm;

[0155] In the horizontal or row direction, the longitudinal spacing between adjacent identical illuminants 31a and illuminants 31a (illuminants 31b and illuminants 31b) is L4, 30 mm ≤ L4 ≤ 80 mm;

[0156] The distance setting of L1, L2, L3 and L4 can prevent the light overlapping areas between the light emitters from being too large and significantly affecting the uniformity of light output.

[0157] In another embodiment of the present invention, the optical component is directly arranged on the mounting portion and fixed by an adhesive. The optical component has no obstruction in the light emitting direction of the LED lamp, forming a complete and continuous light emitting surface, so that the LED lamp has a better light emitting effect and appearance.

[0158] See also Figure 29 and Figure 30 , Figure 29 is a schematic diagram of the three-dimensional structure of an LED lamp in one embodiment of the present invention, Figure 30 FIG. 1 is an exploded front view of an LED lamp in one embodiment of the present invention. Figure 29 As shown, the LED lamp 1000 includes a base 1, a power supply device 2, a light source assembly 3 ( Figure 29 (not shown), optical components 4 and suspension mechanism 6, wherein the power supply device 2, light source assembly 3, optical components 4 and suspension mechanism 6 are all fixed to the base 1. Figure 30As shown, the base 1 includes a bottom plate 10 and side walls 11 arranged around the bottom plate 10 (or the periphery), the bottom plate 10 and the side walls 11 form a receiving groove 14, and the light source assembly 3 is arranged in the receiving groove 14 formed by the bottom plate 10 and the side walls 11. More specifically, the light source assembly 3 is fixed on the bottom plate 10.

[0159] In one embodiment of the present invention, the bottom plate 10 and the side walls 11 are integrally formed. For example, if the base 1 is made of metal, such as iron or aluminum, the bottom plate 10 and the side walls 11 can be integrally formed by stamping or bending. Alternatively, if the base 1 is made of plastic, the bottom plate 10 and the side walls 11 can be integrally formed by injection molding, hot pressing, or the like. The bottom plate 10 and the side walls 11 are formed of the same material.

[0160] In one embodiment of the present invention, the bottom plate 10 and the side wall 11 are separate structures. After the bottom plate 10 and the side wall 11 are formed independently, the bottom plate 10 and the side wall 11 are assembled to form the base 1. The bottom plate 10 and the side wall 11 can be made of the same material or different materials.

[0161] Combine Figure 29 and Figure 30 As shown, in one embodiment of the present invention, an LED lamp is disclosed. The LED lamp 1000 includes a base 1 that constitutes the main frame of the lamp. The base 1 includes a bottom plate 10 that is basically in a horizontal state when installed, that is, the bottom plate 10 is attached to the installation surface and is roughly parallel to the installation surface, and a side wall 11 surrounding the bottom plate 10 (or arranged at the periphery, forming a certain angle with the bottom plate 10 and extending to one side of the bottom plate 10). The side wall 11 has a certain height relative to the bottom plate 10 and forms a receiving groove 14 (also referred to as an receiving space 14) with the bottom plate 10. The receiving groove 14 is used to arrange other components of the LED lamp 1000. For example, in one embodiment of the present invention, a light source assembly 3 is provided in the receiving groove 14. The light source assembly 3 is attached to the bottom plate 10 and is completely accommodated in the receiving groove 14. That is, after the light source assembly 3 is attached to the bottom plate 10, its height is less than or equal to the height of the side wall 11.

[0162] In some other embodiments of the present invention, the light source assembly 3 is at least partially accommodated in the accommodating groove 14 .

[0163] For the sake of convenience, the side of the bottom plate 10 facing the accommodating groove 14 is called the front side of the bottom plate 10, and the other opposite side, that is, the side of the bottom plate 10 facing away from the accommodating groove 14 is called the back side of the bottom plate 10; the side of the side wall 11 facing the accommodating groove 14 is called the inner surface of the side wall 11, and the other opposite side, that is, the side of the side wall 11 facing away from the accommodating groove 14 is called the outer surface of the side wall 11.

[0164] The LED lamp 1000 further includes a power supply device 2 , which is fixed to the base 1 and electrically connected to the light source assembly 3 , for supplying power to the light source assembly 3 and other electrical components of the LED lamp 1 .

[0165] In one embodiment of the present invention, the power supply device 2 is disposed on the side wall 11 , more specifically, on the outer surface of the side wall 11 .

[0166] Of course, in some other embodiments of the present invention, the power supply device 2 may also be disposed in the accommodating groove 14 , for example, the power supply device 2 is disposed on the inner surface of the side wall 11 or the front surface of the bottom plate 10 .

[0167] An optical component 4 is disposed on the end of the accommodating groove 14 away from the base plate 10, i.e., in the light emission path of the light source assembly 3. Specifically, the optical component 4 covers the accommodating groove 14, forming a relatively closed space therewith, thereby providing a certain degree of protection for the light source assembly 3 disposed within the accommodating groove 14. The projection of the optical component 4 on the base plate 10 completely covers the light source assembly 3, and the light emitted by the light source assembly 3 is optically processed and ultimately projected outside the LED lamp 1000.

[0168] See also Figure 31 and Figure 32 ,in Figure 31 This is a schematic diagram of the back of an LED lamp in one embodiment of the present invention. Figure 32 This is an exploded view of the back of an LED lamp in one embodiment of the present invention.

[0169] like Figure 31 As shown, a reinforcement structure 100 is provided on the base plate 10, and the number of the reinforcement structures 100 is at least one, and the reinforcement structures 100 are perpendicular to each other. In one embodiment of the present invention, the reinforcement structure 100 is convex on the back side of the base plate 10 and concave on the front side of the base plate 10. The light source assembly 3 or some other original components can be arranged in the concave formed by the reinforcement structure 100 in the base plate 10, thereby achieving spatial reuse to a certain extent and reducing the height of the light source assembly 3, for example. Furthermore, since the light source assembly 3 needs to maintain a certain distance from the optical component 4 to meet light emission effects such as glare and light uniformity, the light source assembly 3 is arranged in the concave formed by the reinforcement structure 100, which can reduce the overall height of the LED lamp.

[0170] In one embodiment of the present invention, the reinforcement structure 100 and the base plate 10 are integrally formed. For example, when the base plate 10 is made of metal material, the reinforcement structure 100 is integrally formed by stamping the base plate 10. The reinforcement structure 100 is not directly formed relative to the base plate 10 by adding other materials, and will not cause an increase in the original cost; the reinforcement structure 100 has a certain height relative to the base plate 10, that is, the setting of the reinforcement structure 100 makes the base plate 10 no longer a flat surface, and it also increases a certain thickness in the direction perpendicular to the base plate 10, so that the ability of the base plate 10 to resist shear force and lateral pressure is improved. Without adding additional materials, the structural strength of the base plate 10 is enhanced through surface design.

[0171] Of course, in another embodiment of the present invention, the reinforcing structure 100 and the base plate 10 are split structures, that is, after the base plate 10 is independently formed, the reinforcing structure 100 is additionally provided on the front or back side of the base plate 10, for example, by gluing or welding.

[0172] In some other embodiments of the present invention, the reinforcement structure 100 may also be arc-shaped, ring-shaped, broken line-shaped, wavy-shaped, etc. but not limited thereto. The shape of the reinforcement structure 100 can be designed according to the light output requirements to further change the shape of the light source assembly 3.

[0173] like Figure 31 As shown, a mounting portion 12 is provided on one end of the side wall 11 away from the base plate 10. This mounting portion 12 surrounds the side wall 11, is generally parallel to the base plate 10, and extends a certain distance toward the outer surface of the side wall 11. It is used to mount an optical component 4, that is, the optical component 4 is mounted on the side of the mounting portion 12 facing away from the base plate 10. At least one suspension mechanism 6 is provided on the side of the mounting portion 12 facing the base plate 10. The suspension mechanism 6 can be secured to the mounting portion 12 by, for example, screws, gluing, welding, or snaps. The suspension mechanism 6 is then secured to a mounting surface, such as a ceiling, wall, or suspension structure, thereby securing the LED lamp.

[0174] In one embodiment of the present invention, the number of the suspension mechanisms 6 is an even number, such as 2, or 4.

[0175] In another embodiment of the present invention, the number of the suspension mechanisms 6 is an odd number, such as 1, 3, 5, etc.

[0176] In one embodiment of the present invention, the mounting portion 12 and the side wall 11 are integrally formed, that is, the side wall 11 and the mounting portion 12 are integrally stamped from a substrate forming the base 1, such as a flat metal surface. Of course, the side wall 11 can also be formed by bending the side wall 11. When the substrate forming the base 1 is a plastic material, the side wall 11 and the mounting portion 12 can also be formed by hot pressing or injection molding.

[0177] like Figure 32 The figure shows an exploded view of the back of an LED lamp 1000 in an embodiment of the present invention, wherein the suspension mechanism 6 is fixed to the mounting portion 12 by means of screws, the mounting portion 12 is provided with at least one mounting hole, and the suspension mechanism 6 is provided with a locking hole corresponding to the mounting hole. During installation, the locking hole of the suspension mechanism 6 and the mounting hole on the mounting portion 12 correspond one to one, and a locking member (such as a screw, a rivet, etc.) passes through the locking hole and the mounting hole to fix the suspension mechanism 6 to the mounting portion 12.

[0178] See also Figure 33 ,in Figure 33 In one embodiment of the present invention Figure 32 The enlarged view of point F in the figure. Figure 33 As shown, the suspension mechanism 6 includes a connecting portion 61. When the suspension mechanism 6 is secured to the mounting portion 12, the connecting portion 61 abuts against the side of the mounting portion 12 facing the base plate 10. The connecting portion 61 is provided with at least one through-hole locking hole 62. Extending from the side of the connecting portion 61 are a locking reinforcement portion 63 and a hook 64. The locking reinforcement portion 63 is provided with a locking reinforcement hole 631.

[0179] In one embodiment, the locking reinforcement hole 631 can be fixed to the side wall 11 by screws to strengthen the connection between the suspension mechanism 6 and the base 1 .

[0180] In one embodiment, the locking reinforcement hole 631 can be used as a fixing hole for a hanging structure. For example, a hanging chain passes through the locking reinforcement hole 631 to achieve installation and fixation of the LED lamp.

[0181] The hook 64 has a first arm 641, a second arm 642, a third arm 643 and a fourth arm 644 extending to the connecting portion 61. The first arm 641 and the third arm 643 are parallel to each other and are roughly perpendicular to the mounting portion 12 and the connecting portion 61. The second arm 642 and the fourth arm 644 are parallel to each other and are roughly parallel to the mounting portion 12 and the connecting portion 61. The connecting portion 61, the first arm 641, the second arm 642, the third arm 643 and the fourth arm 644 together constitute a "Wei"-shaped structure and are roughly in the same plane, so that the suspension mechanism 6 is a semi-enclosed structure, which is not easy to fall off when fixed.

[0182] See also Figure 34 and Figure 35 , which is a schematic diagram of other implementations of the suspension mechanism 6 in some other embodiments of the present invention, such as Figure 34 Compared with the aforementioned suspension mechanism 6 , the suspension mechanism 6 shown lacks the fourth arm 644 . The hook 64 of the suspension mechanism 6 includes a first arm 641 , a second arm 642 and a third arm 643 .

[0183] like Figure 35 The suspension mechanism 6 shown is another embodiment of the present invention. The suspension mechanism 6 includes a connecting portion 61. When the suspension mechanism 6 is secured to the mounting portion 12, the connecting portion 61 abuts against the side of the mounting portion 12 facing the base plate 10. The connecting portion 61 is provided with at least one through-hole locking hole 62. Extending from the side of the connecting portion 61 are a locking reinforcement portion 63 and a hook 64. The locking reinforcement portion 63 is provided with a locking reinforcement hole 631. The hook 64 includes a first arm 641, a second arm 642, a third arm 643, and a fourth arm 644 extending from the connecting portion 61. The first arm 641 and the second arm 642 are located in the same plane, and the third arm 643 and the third arm 644 are located in the same plane. The planes containing the first and second arms 641 and 642 and the planes containing the third and fourth arms 643 and 644 are substantially perpendicular.

[0184] See also Figure 36 , in one embodiment of the present invention Figure 32 As shown in the enlarged view at point G in the figure, the mounting portion 12 is provided with at least one mounting hole 124. The mounting hole 124 is a through hole, that is, it completely penetrates the mounting portion 12. The locking hole 62 on the connecting portion 61 of the suspension mechanism 6 corresponds to the mounting hole 124. The two are positioned relative to each other and are connected and fixed by screws or rivets.

[0185] In one embodiment of the present invention, each suspension mechanism 6 is provided with two locking holes 62 , and the number of mounting holes 124 provided at the position of the mounting portion 12 corresponding to each suspension mechanism 6 is also two, and the number of locking holes 62 and mounting holes 124 corresponds one to one.

[0186] In one embodiment of the present invention, the number of the locking holes 62 is greater than the number of the mounting holes 124 .

[0187] In one embodiment of the present invention, the number of the locking holes 62 is less than the number of the mounting holes 124 .

[0188] In one embodiment of the present invention, the mounting holes 124 are distributed in a straight line along the mounting portion 12 to facilitate positioning and fixing of the locking holes 62 and the mounting holes 124 .

[0189] In one embodiment of the present invention, the mounting holes 124 are scattered along the mounting portion 12, so that when the LED lamp is fixed to a mounting surface (such as a ceiling, wall, etc.), the mounting portion 12 is subjected to more uniform force, reducing the risk of deformation or damage.

[0190] See also Figures 37 and 38 ,in Figure 37 for Figure 29 A schematic cross-sectional view of the LED lamp along line III-III; Figure 38 In one embodiment of the present invention, Figure 37 A local enlarged view of H in FIG; Figure 39 In one embodiment of the present invention, Figure 30 A partial enlarged view of E in FIG. Figure 37 , wherein the base 1 has a receiving groove 14 formed by a bottom plate 10 and a side wall 11, and the light source assembly 3 is accommodated in the receiving groove 14, more specifically, it is arranged on the bottom plate 10, directly adhered to the bottom plate 10 or indirectly adhered to the bottom plate 10 through a medium, and the optical component 4 is arranged in the light emitting direction of the light source assembly 3, and at least covers part of the light source assembly 3 or completely covers the light source assembly 3. At the same time, the optical component 4 is combined with the mounting portion 12 of the side wall 11 away from the bottom plate 10, so that the receiving groove 14 becomes a relatively sealed space. The light source assembly arranged in the receiving groove 14 can be protected by the base 1 and the optical component 4, that is, the base 1 and the optical component 4 isolate the light source assembly 3 from the external environment, avoiding most of the influence or damage of the external environment on the light source assembly 3.

[0191] In one embodiment of the present invention, the power supply device 2 is disposed outside the side wall 11, that is, outside the relative accommodation space. The power supply device 2 includes a power supply box 20 disposed outside and a circuit assembly 21 and other related electronic components ( Figure 9 Not shown, please refer to Figure 32 ), wherein the power box 20 shares a side wall 11, that is, the power box 20 and the side wall 11 together form a power cavity for accommodating the circuit assembly 21 and other related electronic components. By reusing the side wall 11, the overall cost and weight of the lamp are reduced, while also reducing the volume. The power supply device 2 is disposed in the vacant space between the side wall 11 and the mounting portion 12, relative to the outside of the accommodating groove 14. Utilizing this vacant space to accommodate the power supply device 2 avoids increasing the overall height and volume of the lamp.

[0192] See also Figure 38 and Figure 39 ,like Figure 38 As shown, Figure 38 for Figure 37 In the enlarged view at point H in the figure, the power supply box 20, the side wall 11, and the mounting portion 12 of the side wall 11 together form the power supply cavity. The mounting portion 12 is provided with at least one glue-receiving groove 125. The glue-receiving groove 125 is arranged along the length of the mounting portion 12 and surrounds the outer edge of the LED lamp. The top of each side of the glue-receiving groove 125 contacts the optical component 4, which means that the height of the glue contained in the groove can at least reach the height of the optical component 4 and contact the optical component 4. After the glue cures, it can effectively fix the optical component 4.

[0193] refer to Figure 38 and Figure 39A glue overflow groove 126 is also provided between the mounting portion 12 and the optical component 4. The height and depth of the glue overflow groove 126 are similar to those of the glue containing groove 125. It can be used to accommodate glue overflowing from the glue containing groove 125 to prevent the glue from contaminating other areas of the lamp. At the same time, the depth of the glue overflow groove 126 is at least greater than the height of the screws (or rivets and other fixing parts) used to fix the suspension mechanism 6, thereby preventing the screw structure for fixing the suspension mechanism 6 from damaging the integrity of the light-emitting surface (also known as the light-emitting cover). In other words, the outer side of the mounting portion 12 has a bending portion limit frame 127. The bending portion limit frame 127 is provided along the light-emitting direction of the LED lamp. Its highest position is higher than the highest position of the glue containing groove 125, forming an installation step with it. That is, the optical component 4 is superimposed on the highest point of the glue containing groove 125, and the outermost edge of the optical component 4 is blocked by the bending portion limit frame 127, thereby forming a closed package and preventing the optical component 4 from shifting.

[0194] In one embodiment of the present invention, the height of the bending portion limiting frame 127 is equal to the thickness of the optical component 4 , and the two fit together, so that the surface of the LED lamp in the light emitting direction is complete.

End caps 202 are provided at each end of the power box 20's length. The end caps 202 can be integrally formed with the power box 20 or separately formed and then assembled to the power box 20.

[0213] In another embodiment of the present invention, the power box 20 may also be fixed to the base 1 by gluing, welding, or snapping.

[0214] The power supply unit 2 includes a circuit board and various electronic components thereon, which enable dimming and color adjustment functions of the LED lamp 1000. Specifically, the light emitter 31 of the present invention can be composed of lamp beads with only one color temperature and color, or it can be composed of lamp beads with at least two color temperatures and colors. The combination of lamp beads with different color temperatures and colors enables the dimming and color adjustment functions of the LED lamp 1000.

[0217] In one embodiment of the present invention, different types of lamp beads are respectively provided on at least two circuit boards 30, and the types of lamp beads on a single lamp board are the same, that is, the light source component 3 realizes different light intensity, color temperature, color and other functions through the configuration of different lamp beads, further realizing the dimming and color adjustment of the LED lamp.

[0218] Color adjustment can be performed using buttons and / or knobs on the wall. For example, each time a button is pressed, the color changes; turning the knob changes the brightness.

[0219] In order to further improve the assembly efficiency of the power supply device and save installation materials and installation steps, an embodiment of the present invention provides an improved grounding method for the power supply device. Figure 49B The diagram shows a grounding system for a power supply device. The power supply device 2 is provided with a snap-on portion 24a. Specifically, the snap-on portion 24a can be secured to the power supply box 20 or the power supply box fixing plate 201 (not shown) by welding or bonding. The snap-on portion 24a acts as a female socket. The user connects the ground wire 9 in the installation environment as a male plug to the female snap-on portion 24a, thereby achieving an electrical connection between the power supply device 2 and the ground wire 9.

[0220] Figure 49C This diagram shows another grounding method for a power supply unit. Power supply unit 2 is provided with a screw portion 24b. Specifically, screw portion 24b has a hollow structure and is embedded in power supply box 20 or power supply box fixing plate 201 (not shown). The user inserts the ground wire 9 (male connector) of the installation environment into the hollow structure of screw portion 24b (female connector), thereby establishing an electrical connection between power supply unit 2 and ground wire 9.

[0221] Figure 49D and Figure 49E The following diagram shows the structure and grounding configuration of another embodiment of a power supply device. A recessed socket 24c is provided on the power supply device 2. In one embodiment, the recessed socket 24c is integrally formed with the power supply box 20. Specifically, the recessed socket 24c can be provided on the power supply box 20 or the power supply box fixing plate 201 (not shown in this figure). The user inserts the ground wire 9 of the installation environment as a male plug into the recessed socket 24c (female socket), thereby establishing an electrical connection between the power supply device 2 and the ground wire 9.

[0222] The grounding form adopted in the above embodiments saves the operation steps of screws and the power ground wire in the prior art, as well as the step of folding and placing the power ground wire in the power supply box; and the user directly inserts or snaps the earth wire 9 into the grounding interface (female socket), omitting the step of connecting the power ground wire and the earth wire 9 with a nut, which is safer and more convenient.

[0223] An LED lamp in an embodiment of the present invention can be installed in the ceiling of a house. Since it is rectangular, when installing, first remove 1 grid of the ceiling to form a vacancy, and then place the LED lamp into the vacancy. Figure 31 and Figure 32 As can be seen, the side of the LED lamp is trapezoidal, so that it is convenient for the smaller end to enter the ceiling during installation, forming an embedded installation. This installation method can make there be almost no gap between the LED lamp and the ceiling. If better sealing is required, a soft sealing layer can be provided on the side of the installation part 12 facing the ceiling.

[0224] As mentioned above, the LED lamp is installed in the vacancy of the ceiling. Specifically, as Figure 43 shown, Figure 43 A schematic diagram of the lamp disposed in the ceiling in an embodiment, where 1 grid is removed from the ceiling 60 to form a ceiling vacancy 600 for installing the LED lamp 1. A plurality of horizontally extending mounting rods 601 are provided at the edge of the ceiling vacancy 600, and the hanging mechanism 6, more precisely the hook 64 part, is fixed to the mounting rod 601 to complete the fixing of the LED lamp.

[0225] In an embodiment of the present invention, the above-mentioned LED lamp, different from the traditional wire wiring method, uses a wiring component 7 to realize the conduction of at least some electronic components in the LED lamp, thereby simplifying the internal wiring of the LED lamp.

[0226] As Figure 44 shown, it shows a partially disassembled structural schematic diagram of an LED lamp in an embodiment of the present invention. The light source component 3 is arranged on the bottom plate 10, and the light source component 3 is electrically connected to the power supply device 2 (not shown in the figure) through the wiring component 7. The wiring component 7 can be a wire with a certain hardness and plasticity, such as a single-strand tinned copper wire. As shown in Figure 45, it is Figure 44 a partial enlarged view of I in the figure. The circuit board 30 has a plurality of pads 33. The number of wiring components 7 matches the number of the pads 33. The wiring component 7 is fixedly connected to the pad 33 by heating and melting the solder paste 8. The wiring component 7 uses a simple fixture to punch out a turning part 71 to achieve an insulating effect that the wiring component 7 does not contact the bottom plate 10. Before the solder paste 8 is heated and welded, it is arranged in two upper and lower parts on the pad 33, approximately in the shape of the Chinese character "day", with a gap in the middle. The wiring component 7 is located in the gap and contacts the pad 33.

[0227] A connecting portion 113 is inserted into the connection port 112 on the side wall 11, and the connecting element 7 connected to the light source assembly 3 is electrically connected to 2 through the connecting portion 113, that is, the connecting element 7 passes through the connecting portion 113. Figure 46 FIG. 1 is a schematic diagram of a partially disassembled structure of an LED lamp according to an embodiment of the present invention, wherein the enlarged view of part J is shown in FIG. Figure 47 As shown, the connecting portion 113 includes a hollow portion 1131 and a conductive portion 1132 . The wiring element 7 enters from the hollow portion 1131 and connects to the connecting portion 113 . The conductive portion 1132 contacts the power supply device 2 .

[0228] like Figure 48 As shown, the power supply device 2 has a clamping portion 210 and a power board 22, wherein one end of the clamping portion 210 is fixed to the power board 22, and the other end has a first clamping portion 211, and a third clamping portion 213 is provided on the side close to the power board 22, and a second clamping portion 212 is provided between the first clamping portion 211 and the third clamping portion 213. In this embodiment, when the power supply device 2 is arranged outside the concave cavity 14, the conductive portion 1132 is connected to the clamping portion 210, wherein the end of the first clamping portion 211 away from the second clamping portion 212 is wider than the diameter of the conductive portion 1132, which is convenient for the conductive portion 1132 to clamp. Entering the first clamping portion 211, the portion of the first clamping portion 211 away from the second clamping portion 212 gradually reduces in width along the direction of the second clamping portion 212 to a width slightly smaller than the diameter of the conductive portion 1132, so as to facilitate limiting the position of the conductive portion 1132. The size of the second clamping portion 212 is adapted to the conductive portion 1132, and the position where the second clamping portion 212 is connected to the third clamping portion 213 is also slightly smaller than the diameter of the conductive portion 1132, so as to limit the position of the conductive portion 1132. The width of the third clamping portion 213 is smaller than the diameter of the conductive portion. In this embodiment, the clamping portion 21 can be a copper spring.

[0229] The specific connection process between the power supply device 2 and the connecting part 113 is as follows: the conductive part is first snapped into the first snap-fitting part, and then slides into the second snap-fitting part along the connection position between it and the second snap-fitting part. Since the second snap-fitting part is adapted to the size of the conductive part, and the third snap-fitting part is smaller than the diameter of the conductive part, the conductive part can be connected to the second snap-fitting part, thereby realizing the electrical connection between the power supply device and the light-emitting component. The number of the snap-fitting parts matches the number of the conductive parts.

[0230] The assembly method of the LED lamp includes the following steps: providing a connecting part, a light-emitting component, a wiring element, a base and a power supply device, firstly inserting the wiring element into the connecting part from the conductive part side, and cutting off the wiring element after extending it to a length sufficient to connect to the light source component, and using a simple jig to punch the wiring element connected to the connecting part into a tooth shape with a bending part. This method avoids the need for wire stripping in the previous process, and can continuously load large rolls, reduce the number of shutdowns for material change, and shorten the material change time; setting solder paste in the welding area of ​​the light-emitting component, and when there are multiple groups of light-emitting components, placing the punched wiring element on the light-emitting component. There is no need to feed tin wire separately to the tin seam formed by the solder paste in the welding area. Since the wiring element has a bend, it can be insulated from the floor. Multiple solder joints can be welded simultaneously by a machine device, which can be a galvanometer laser welding machine. The welded wiring element and the light-emitting component are fixed in the concave cavity of the base. The fixing method can be glue, welding, screws and clips. The connecting part connected to the wiring element is installed on the side wall of the LED lamp. Finally, the clamping part of the power supply device is connected to the connecting part, thus realizing the electrical connection between the power supply device and the light-emitting component. The above method can realize fully automated mass production, which reduces production costs and achieves good finished product effects.

[0231] In summary, the LED lamp and its assembly method and packaging method disclosed in the present invention are as follows: (1) a frame is provided which is fixed by inserting and sleeved the frame, so that the optical component can be fixed on the mounting portion without additional fixing parts, which is simple to assemble and reduces the product defect rate and process complexity caused by fixing with fixing parts; (2) a folding portion is added to the base of the lamp to fix the optical component by folding the folding portion, omitting the use of a frame, saving materials, further improving production efficiency and reducing costs; (3) the side wall of the base is provided with at least two inclined portions to increase the width of the power supply device configuration space that can be provided by the side wall, greatly reducing the requirements for the width of the mounting portion, and being able to achieve an extremely narrow shielding area, greatly improving the light output ratio and light output effect, and also increasing the aesthetics of the lamp; (4) the power supply device is provided to protrude from the bottom plate to form a height difference with the bottom plate, so that when the two LED lamps are placed with the bottom plates in contact, there is an overlapping area in the vertical direction, so that the two LED lamps can be packaged and transported in a manner where the bottom plates of the two LED lamps are in contact, reducing the height space required for packaging and transportation, and greatly saving packaging and transportation costs. (5) Set the intervals or stagger the lamp beads of different color temperatures to achieve uniform light output without obvious bright spots.

[0232] In order to further ensure the safety of LED lamps during use, a layer of insulation is usually placed on the outside of the power supply component to isolate the power box from the power supply component to avoid leakage accidents. In practical applications, the following is generally used: Figure 50The Mylar sheet 10 shown is used as an insulator and is arranged on the outside of the power supply component 21. The Mylar sheet 50 is a one-piece structure with an indentation. It is a hard plastic with strong insulation, moisture resistance and high temperature resistance. However, it can only be pre-folded by hand, which is difficult to fold. The formed Mylar sheet is then put on the power supply component, and the installation speed is slow, resulting in low overall assembly efficiency of the power supply.

[0233] Therefore, in one embodiment of the present application, a power box is proposed, which has an inner surface close to the power component and an outer surface in contact with the base. The inner surface is provided with a coating, and the coating has the characteristics of low thermal resistance, wear resistance, puncture resistance, moisture resistance, high temperature resistance, etc., which is used to electrically insulate the power component from the power box and dissipate the heat generated by the power component.

[0234] The coating may be plastic, ceramic or metal oxide, such as polytetrafluoroethylene, aluminum oxide and the like.

[0235] The coating can be fixed to the inner surface of the power box by gluing or coating. When the power supply assembly is fixed inside the power box, for example, by screws, the coating can be provided locally at locations where the power supply assembly is likely to contact the inner surface of the power box, or it can be provided on the entire inner surface of the power box. In some embodiments, the power supply assembly may not be fixed inside the power box.

[0236] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
