Description

Technical Field

[0001] This invention relates to the field of downlight technology, and in particular to a modular pre-installed downlight. Background Technology

[0002] Pre-installed downlights, also known as frameless downlights, have become a mainstream lighting choice for homes and commercial spaces due to their "light without seeing the lamp" effect. These downlights typically use an embedded installation method and generally consist of a pre-installed panel and a lamp body structure composed of a heat sink, light source module, lens, and anti-glare cover. During installation, the lamp body is fixed in place by the pre-installed panel and the ceiling, resulting in a seamless integration of the lamp body with the ceiling surface, effectively avoiding the visual interruption of the ceiling space by traditional lighting fixtures. In interior design without a main light source, the splicing installation of multiple pre-installed downlights is widely used, forming a unified luminous area through the combination of multiple lights to meet the basic lighting needs of the design scenario.

[0003] In existing technologies, the splicing method of multiple downlights relies on the independent installation of adjacent pre-mounted panels. To ensure the installation stability of each downlight, the pre-mounted panel needs to maintain sufficient contact area with the ceiling and be equipped with multiple sets of fastening structures. However, the structural design of the pre-mounted panel directly limits the reduction of the spacing between two adjacent downlights. Excessive spacing between the lights will result in ineffective connection of the light from adjacent downlights, making it difficult to form a continuous surface light source. In addition, the lack of matching positioning structures between adjacent pre-mounted panels and between adjacent light bodies leads to installation misalignment when splicing multiple lights, causing multiple light bodies to be out of line, resulting in uneven light-emitting edges, reducing the overall quality of spatial lighting, and failing to meet the requirements of spliced ​​downlights for continuous, uniform, and neat lighting.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a modular pre-installed downlight to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A modular pre-installed downlight includes at least two downlight units, each of which can be detachably assembled along the X and / or Y directions; each downlight unit includes: The pre-installed panel has several break lines, all of which form a grid structure to divide the pre-installed panel into one installation area and eight pre-installed areas. A radiator is installed in the installation area. Two sets of symmetrically arranged first inserts and two sets of symmetrically arranged second inserts are provided on the outer periphery of the radiator. The two sets of first inserts and the two sets of second inserts are orthogonally distributed along the circumference of the radiator. An installation cavity is provided inside the radiator.

The anti-glare shield is detachably connected to a lens, and the light-inlet side of the lens is located on the light-outlet side of the COB module. When adjacent downlight units are spliced, the overlapping pre-installed areas on the adjacent pre-installed plates are removed by breaking along the break line, so that the installation areas of each downlight unit are adjacent and arranged on the same plane, and the first plug-in of the heat sink of one downlight unit is adapted and fitted to the second plug-in of the heat sink of the adjacent downlight unit.

[0007] Furthermore, a number of through holes are provided between adjacent installation areas and pre-installation areas, and between two adjacent pre-installation areas, and the through holes are arranged at intervals along the extension direction of the corresponding break line.

[0016] Beneficial effects: The present invention provides a splicing pre-installed downlight with the following beneficial effects: (1) Through the structural design of the "well" shaped break line and eight pre-installed areas, only the overlapping pre-installed areas need to be removed during splicing, which can reduce the distance between lamp bodies and retain sufficient contact area to ensure installation stability; adjacent heat sinks are assembled by the first plug and the second plug, so that the distance between lamp bodies is compressed to the width of a single heat sink, and the splicing distance is uniform, and the lighting is seamlessly connected. At the same time, it supports flexible splicing in the X and Y directions, which can adapt to the lighting layout requirements of different spaces; (2) The COB module is detachably connected to the mounting part through the magnetic structure, and the first elastic pin electrode and the second elastic pin electrode are elastically abutted, so that the lamp can be quickly disassembled and replaced without disassembling the whole lamp; the anti-glare cover is installed by snap-fit ​​and is detachably connected to the lens. The lens can be replaced to adjust the light emission angle. With the replaceable COB module, the color temperature can be adjusted, which can adapt to various lighting scenarios and improve the applicability and flexibility of the lamp.

[0019] This invention provides a modular pre-installed downlight. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0021] Please see Figures 1 to 10As shown, the present invention provides a modular pre-installed downlight, comprising: at least two downlight units 10, each downlight unit 10 being detachably spliced ​​along the X and / or Y directions; each downlight unit 10 comprising: a pre-installed plate 1, a heat sink 2, a COB module 3, and an anti-glare cover 4; the pre-installed plate 1 is provided with a plurality of break lines 11, all break lines 11 forming a "well" shaped structure to divide the pre-installed plate 1 into one installation area 12 and eight pre-installed areas 13; the heat sink 2 is disposed on the installation area 12, and the outer periphery of the heat sink 2 is provided with two sets of symmetrically arranged first plug-in 21 and two sets of symmetrically arranged second plug-in 22, the two sets of first plug-in 21 and the two sets of second plug-in 22 being connected to each other. The components 22 are orthogonally distributed along the circumference of the heat sink 2; the heat sink 2 is provided with a mounting cavity 23; the COB module 3 is located in the mounting cavity 23; the anti-glare cover 4 is located at the opening end of the mounting cavity 23, and the anti-glare cover 4 is detachably connected to a lens 5, and the light-inlet side of the lens 5 is located on the light-outlet side of the COB module 3; when adjacent downlight units 10 are spliced, the overlapping pre-installed areas 13 on the adjacent pre-installed plates 1 are removed by breaking along the break line 11, so that the mounting areas 12 of each downlight unit 10 are adjacent and coplanar, and the first plug-in 21 of the heat sink 2 of one downlight unit 10 is adapted and fitted with the second plug-in 22 of the heat sink 2 of the adjacent downlight unit 10.

[0022] During the splicing operation, first determine the splicing direction of the downlight unit 10 according to the actual lighting requirements, such as X-direction, Y-direction, or XY-direction combination, and place at least two downlight units 10 in a corresponding layout according to the preset layout; for the overlapping area of ​​the pre-installed plate 1 of adjacent downlight units 10, directly break and remove the overlapping pre-installed area 13 along the "well" shaped break line 11, so that the installation area 12 in the center of each downlight unit 10 naturally forms an adjacent and coplanar arrangement; at the same time, use the first plug-in 21 on the outer periphery of the heat sink 2 of one downlight unit 10 to correspondingly fit with the second plug-in 22 on the outer periphery of the heat sink 2 of the adjacent downlight unit 10. Since the two sets of first plug-in 21 and two sets of second plug-in 22 are orthogonally distributed along the circumference of the heat sink 2, the alignment under different splicing directions is realized, and the rapid splicing and fixing of multiple downlight units 10 is completed. After assembly, the heat sink 2 of each downlight unit 10 is fixedly connected to the corresponding mounting area 12 of the pre-installed plate 1 with screws, so that multiple downlight units 10 are spliced ​​into a whole. Finally, the remaining pre-installed areas 13 of each downlight unit 10 are fastened with fasteners to fix the spliced ​​whole downlight assembly to the preset position on the ceiling. When the lighting is turned on, the COB module 3 in the mounting cavity 23 of the heat sink 2 emits light. The light is received and refracted by the light-inlet side of the lens 5, and then optimized and emitted through the anti-glare cover 4 to achieve stable lighting output. The above-mentioned structural design of the "well"-shaped break line 11 and eight pre-installed areas 13 ensures that when adjacent downlight units 10 are spliced, only the overlapping interference parts need to be removed, and the remaining pre-installed areas 13 can still guarantee sufficient contact area with the ceiling. This significantly reduces the spacing between adjacent downlights while ensuring that installation stability is not affected. The orthogonal distribution of the first plug-in 21 and the second plug-in 22 not only achieves precise positioning of adjacent lamp bodies and limits relative displacement, but also ensures that the installation areas 12 of each downlight unit 10 are coplanar and the luminous surfaces are flush, avoiding misalignment problems caused by manual installation errors. The detachable splicing design supports flexible combination to adapt to the lighting layout needs of different spaces, and the illumination of each downlight unit 10 can be seamlessly connected after splicing, forming a continuous and uniform overall luminous area.

[0023] In a preferred embodiment, see [reference] Figure 3 A plurality of through holes 111 are provided between adjacent installation areas 12 and pre-installation areas 13, and between two adjacent pre-installation areas 13. The through holes 111 are arranged at intervals along the extension direction of the corresponding break line 11. By setting the through holes 111, the structural strength at the break line 11 can be effectively weakened, providing assistance for the pre-installation plate 1 to be broken along the break line 11 and reducing the difficulty of operation. In actual operation, first, the installation area 12 of the pre-installation plate 1 and the pre-installation area 13 to be retained are placed stably on the platform, so that the overlapping pre-installation area 13 to be removed is suspended outside the platform to avoid support interference; then, a flat plate is used to press the installation area 12 and the retained pre-installation area 13 to prevent the pre-installation plate 1 from deforming during the breaking process and to ensure the flatness of the installation area 12; finally, the suspended pre-installation area 13 to be removed is held by hand and repeatedly bent up and down along the break line 11 to easily break and remove it, obtaining the shape of the pre-installation plate 1 that meets the splicing requirements. The operation is convenient and does not easily damage the remaining structure.

[0024] For different splicing scenarios, the specific removal methods and splicing processes for pre-installed area 13 are as follows: Figure 2 As shown, when splicing two downlight units 10, the three pre-installed areas 13 on the right side of the pre-installed plate 1 of the downlight unit 10 on the left side need to be removed, and the three pre-installed areas 13 on the left side of the pre-installed plate 1 of the downlight unit 10 on the right side need to be removed. After the heat sinks 2 of the two downlight units 10 are spliced ​​in the preset direction, each heat sink 2 is fixedly connected to the corresponding pre-installed plate 1 to form a downlight assembly spliced ​​along the X or Y direction.

[0025] like Figure 4As shown, when splicing three or more downlight units 10 in a single direction, the pre-mounted plate 1 of the leftmost downlight unit 10 needs to remove the three pre-mounted areas 13 on the right side; the pre-mounted plate 1 of the middle downlight unit 10 needs to remove the six pre-mounted areas 13 on the left and right sides; and the pre-mounted plate 1 of the right downlight unit 10 needs to remove the three pre-mounted areas 13 on the left side. After all the heat sinks 2 of the downlight units 10 are spliced ​​along the preset direction, each heat sink 2 is fixedly connected to the corresponding pre-mounted plate 1 to form a downlight assembly spliced ​​along the X or Y direction.

[0026] like Figure 5 As shown, when multiple downlight units 10 are spliced ​​in a rectangular array, such as a 2×2 splicing array of four downlight units 10, the downlight units 10 located at the four corners of the array have their five pre-installed areas 13 removed from the diagonal positions respectively; after the heat sinks 2 of the four downlight units 10 are arranged in a matrix and spliced ​​in the XY direction, each heat sink 2 is fixedly connected to the corresponding pre-installed plate 1, thus forming a spliced ​​downlight assembly that extends simultaneously in the X and Y directions.

[0027] In a preferred embodiment, see [reference] Figure 3 Each pre-installed area 13 is provided with a hole group 131 and mounting holes 132. The mounting holes 132 are used to fix the pre-installed plate 1 to the ceiling using fasteners. Specifically, the hole group 131 consists of several small holes arranged in a matrix, with the small hole in the center of the matrix serving as the mounting hole 132. The mounting hole 132 is fixedly connected to the ceiling by fastening screws, providing core support for the pre-installed plate 1. At the same time, the shape of the pre-installed plate 1 can be flexibly changed by breaking along the "well"-shaped break line 11, and each retained pre-installed area 13 can maintain a large contact area with the ceiling. Each retained pre-installed area 13 can also be individually fixed to the ceiling by its own fastening screws, ensuring the installation stability of the overall downlight assembly from multiple directions. When applying putty to the ceiling, the putty can cover the surface of the pre-installed plate 1. The multiple small holes in the hole group 131 can increase the contact area and interlocking force between the putty and the pre-installed plate 1, effectively improving the connection firmness between the pre-installed plate 1 and the ceiling. In addition, a positioning hole 121 is provided in the installation area 12. The radiator 2 is fixedly connected to the installation area 12 by fastening screws, and the outlet end of the installation cavity 23 of the radiator 2 is coaxially arranged with the positioning hole 121. After the puttying process is completed, the pre-installed plate 1 is completely embedded in the ceiling to realize the embedded installation of the downlight unit 10, so that the lamp body is perfectly integrated with the ceiling surface, achieving the lighting aesthetic effect of "seeing the light but not the lamp".

[0028] In a preferred embodiment, see [reference] Figure 2It also includes a connecting strip 20, wherein the heat sink 2 of one downlight unit 10 is detachably connected to the heat sink 2 of the adjacent downlight unit 10 via at least one connecting strip 20. Specifically, the end face of the heat sink 2 away from the anti-glare cover 4 is provided with a threaded hole 26; during splicing, after the adjacent downlight units 10 are positioned in the X or Y direction by fitting and engaging the first plug 21 and the second plug 22, the connecting strip 20 is straddling the end faces of the two heat sinks 2, and the first screw 201 passes through the end of the connecting strip 20 and the threaded hole 26 of the heat sink 2 in sequence to form a tight connection, which effectively limits the axial movement of the adjacent heat sinks 2, and further enhances the stability of the splicing, prevents the relative displacement of the adjacent lamp bodies, and improves the splicing firmness and structural integrity of the overall downlight assembly.

[0029] In a preferred embodiment, see [reference] Figure 6 The radiator 2 has two symmetrically arranged first fin groups and two symmetrically arranged second fin groups on its outer periphery. Specifically, the first fin groups and the second fin groups are orthogonally distributed on the outer periphery of the radiator 2. The first fin group includes several spaced-apart first heat dissipation fins 24 extending along the X direction. The free end of the first insert 21 has a first insert 211 extending away from the first fin group, and the free end face of the first insert 211 is coplanar with the free end face of the first heat dissipation fin 24. The second fin group includes several spaced-apart second heat dissipation fins 25 extending along the Y direction. The free end of the second insert 22 has a second insert 221 extending towards the second fin group, and the distance between the free end face of the second insert 221 and the second heat dissipation fin 25 is the thickness of the first insert 211. Specifically, the first insert 21 and the second insert 22 are integrally formed at the ends of the first fin group and the second fin group, respectively, forming an integrated structural design with the heat dissipation fins. During splicing, the first insert 21 and the second insert 22 of adjacent downlight units 10 form a fitting engagement: the first insert 211 of one of the heat sinks 2 can be precisely inserted into the gap between the second insert 221 and the second heat sink 25 of the adjacent heat sink 2 along the direction of the free end face of the second heat sink fin 25; at the same time, the second insert 221 extends towards the direction of the second fin group, which can form a lateral limit on the inserted first insert 211, effectively preventing relative displacement along the X and Y directions after splicing, and ensuring the structural stability of the two heat sinks 2 after splicing. Through the above splicing structure, the spacing between adjacent downlight units 10 can be reduced to the width of a single heat sink 2, which is the width direction in the X or Y direction, consistent with the splicing direction. Compared with the traditional splicing scheme, the spacing is greatly compressed, and the splicing spacing of all adjacent downlight units 10 can be completely consistent, thereby ensuring that the light-emitting surfaces of each lamp are flush and the illumination is seamless, ultimately forming a continuous and uniform overall light-emitting area.

[0030] In a preferred embodiment, see [reference] Figure 7 , 8The heat sink 2 has a mounting cavity 23 with a mounting part 231, and two first elastic needle electrodes 6 on the mounting part 231. The COB module 3 is detachably connected to the mounting part 231 via a magnetic structure 7. The COB module 3 is electrically connected to two second elastic needle electrodes 31, and the two first elastic needle electrodes 6 and the two second elastic needle electrodes 31 correspond one-to-one and elastically abut against each other. In the lighting state, the driving power supply connected to the circuit system inside the heat sink 2 supplies power to the COB module 3. The current is conducted to the COB module 3 through the first elastic needle electrodes 6 and the second elastic needle electrodes 31. The COB module 3 emits light, and the emitted light is refracted by the lens 5 to adjust the light emission angle, and then filtered by the anti-glare cover 4 to achieve uniform and soft lighting output. As described above, the detachable connection between the anti-glare cover 4 and the heat sink 2, and the detachable connection between the anti-glare cover 4 and the lens 5, allows for flexible adjustment of the light emission angle of the downlight unit 10 by replacing lenses of different specifications. The COB module 3 is detachably connected to the mounting part 231 via the magnetic structure 7, and the elastic contact between the first elastic needle electrode 6 and the second elastic needle electrode 31 allows for easy replacement of COB modules 3 with different power and color temperatures, thereby adjusting the luminous brightness and color temperature of the downlight unit 10. Through the above settings, it can flexibly adapt to the lighting needs of different scenarios, improving the applicability and flexibility of the downlight unit 10.

[0031] In the above embodiment, the heat sink 2 also serves as the lamp body structure of the downlight unit 10. It is integrally molded with the mounting part 231, which not only reduces the number of lamp body components, making the overall structure simpler and more compact, but also allows the lamp body to participate in heat conduction as a heat dissipation structure throughout the process, significantly improving heat dissipation efficiency. A second circuit board 61 is connected to the side of the mounting part 231 away from the COB module 3. Two first elastic pin electrodes 6 are fixed to and electrically connected to the second circuit board 61. The second circuit board 61 is also electrically connected to a wire, which forms a conductive circuit with the driving power supply (not shown in the accompanying drawings). Simultaneously, the two first elastic pin electrodes 6 extend towards the side of the mounting part 231 facing the COB module 3, enabling precise docking with the second elastic pin electrodes 31 of the COB module 3. Through the contact of the elastic pin electrodes, the contact resistance is ≤0.1Ω, ensuring conductive stability. During assembly, the COB module 3 is embedded in the mounting cavity 23 of the heat sink 2 and is firmly fixed to the mounting part 231 by the magnetic structure 7, so that the heat generated by the COB module 3 during operation can be directly conducted to the heat sink 2 through the mounting part 231 to achieve efficient heat conduction; combined with the first fin group and the second fin group, the heat dissipation effect of the lamp body is ensured, and the long-term stable operation of the COB module 3 is guaranteed.

[0032] See above. Figure 9The COB module 3 includes a base 32, a first circuit board 33, and a pressure cover 34. The base 32 is fixedly connected to the pressure cover 34 by a second screw 35. The first circuit board 33 is located between the base 32 and the pressure cover 34. A COB light source 36 is provided on the first circuit board 33. Two second elastic needle electrodes 31 are electrically connected to the first circuit board 33 and extend to the side of the base 32 facing the mounting part 231. Through the above arrangement, not only is a firm assembly relationship formed between the first circuit board 33, the COB light source 36, and the second elastic needle electrodes 31, ensuring the stability of the COB module 3's own structure; when the COB module 3 is assembled with the mounting part 231, combined with the adsorption and positioning effect of the magnetic structure 7, the second elastic needle electrodes 31 can accurately align and adhere to the first elastic needle electrodes 6 on the mounting part 231, which quickly completes mechanical fixation and ensures the reliability of circuit conduction, thereby realizing stable light emission of the COB light source 36.

[0033] In a preferred embodiment, see [reference] Figure 7 , 8 The magnetic attraction structure 7 includes a plurality of first magnets 71 and a plurality of second magnets 72. Both the first magnets 71 and the second magnets 72 are permanent magnets, with a magnetic attraction force of 2N. Utilizing the physical principle of opposite poles attracting each other in permanent magnets, the COB module 3 and the mounting part 231 can be detachably fixed. Specifically, the plurality of first magnets 71 are embedded in the side of the mounting part 231 facing the COB module 3, and the plurality of second magnets 72 are embedded in the side of the COB module 3 facing the mounting part 231; the first magnets 71 and their corresponding second magnets 72 are arranged with opposite magnetic poles attracting each other. During assembly, reliable adsorption is achieved through precise polarity alignment.

[0034] Preferably, there are two of each of the first magnet 71 and the second magnet 72. The two first magnets 71 are symmetrically embedded on the side of the mounting part 231 facing the COB module 3, and the magnetic poles of the end faces of the two first magnets 71 facing the second magnet 72 are opposite. The two second magnets 72 are correspondingly symmetrically embedded in the base 32 of the COB module 3, and the magnetic poles of the end faces of each first magnet 71 and the corresponding second magnet 72 are opposite. Through the symmetrical arrangement of magnets, not only can the adsorption force be evenly distributed between the COB module 3 and the mounting part 231, ensuring the stability of the connection, but also the opposite positioning effect of the magnetic poles can effectively prevent misalignment during the assembly of the COB module 3, thereby ensuring that the second elastic pin electrode 31 on the COB module 3 is precisely aligned and reliably abutted with the corresponding first elastic pin electrode 6 on the mounting part 231, ensuring the stability of the circuit conduction.

[0035] It should be noted that, in addition to using magnets with opposite magnetic poles as described above, the magnetic structure 7 can also be a combination of a magnet and a magnetic chuck. The magnet is a permanent magnet, and the magnetic chuck is made of ferromagnetic material. By utilizing the adsorption force between the permanent magnet and the ferromagnetic material, the COB module 3 and the mounting part 231 can be quickly assembled and disassembled. The magnet and the magnetic chuck are respectively located on the mounting part 231 and the COB module 3. During assembly, the precise alignment and mutual adsorption of the two make the COB module 3 firmly attached to the mounting part 231, while also facilitating rapid separation under external force.

[0036] For easier installation and removal of COB module 3, please refer to... Figure 8 , 9 11. The COB module 3 has two symmetrically arranged U-shaped connecting ears 341 on the side facing the lens 5. The U-shaped connecting ears 341 are integrally formed with the cover 34 of the COB module 3. With the above setup, when COB module 3 needs to be disassembled, the operator can use the matching U-shaped clip 30, which has horizontally outwardly extending insertion parts 301 at both ends. The two insertion parts 301 are respectively inserted into the U-shaped connecting ears 341, and then a steady pulling force is applied in the direction away from the mounting part 231. This can easily overcome the attraction force of the magnetic structure 7, allowing COB module 3 to smoothly detach from the mounting part 231 along the axial direction, avoiding damage to components due to uneven force during disassembly and assembly. When COB module 3 needs to be installed, COB module 3 is first placed into the mounting cavity 23, and then the U-shaped connecting ears 341 are gently pushed to cause COB module 3 to rotate slightly. Under the magnetic attraction force of the magnetic structure 7, COB module 3 can automatically and accurately position itself with the mounting part 231 and quickly adhere to it. At the same time, the first elastic needle electrode 6 on the mounting part 231 is triggered to generate axial compression deformation, so that the first elastic needle electrode 6 and the second elastic needle electrode 31 of COB module 3 are tightly abutted, reliably realizing circuit conduction.

[0037] Preferably, see Figure 9 The downlight unit 10 also includes several third screws 9, and the COB module 3 is detachably connected to the mounting part 231 via the third screws 9. The fixing structure of the third screws 9 and the magnetic structure 7 form a double fixing cooperation. The magnetic structure 7 is used to complete the rapid pre-positioning and initial adsorption fixing of the COB module 3, and then the third screws 9 are used for locking and reinforcement, which effectively improves the assembly stability of the COB module 3 and the mounting part 231.

[0038] In a preferred embodiment, see [reference] Figure 7 , 10The inner wall of the opening end of the mounting cavity 23 is provided with an annular stepped portion 232; the outer periphery of the anti-glare cover 4 is adapted to the end of the mounting cavity 23; the outer periphery of the anti-glare cover 4 is provided with a plurality of first latches 41, which engage with the annular stepped portion 232 to realize a quick and detachable connection between the anti-glare cover 4 and the radiator 2.

[0039] Specifically, the first latch 41 has an elastic cantilever structure, and its free end is provided with an outwardly protruding latch 411. The latch 411 has a first inclined surface 412 on the side facing the mounting part 231. When the latch 411 slides into the annular stepped part 232 along the first inclined surface 412, it is compressed and retracts inward. After passing the edge of the annular stepped part 232, it automatically rebounds and locks itself into the annular stepped part 232. The latch 411 has a second inclined surface 413 on the side away from the mounting part 231. When disassembling, force is applied outward along the axial direction, and the latch 411 slides out of the annular stepped part 232 along the second inclined surface 413, so that the anti-glare cover 4 can be easily removed.

[0040] Preferably, there are two first latches 41, symmetrically distributed around the outer periphery of the anti-glare cover 4, which ensures both reliable latching and ease of disassembly and assembly.

[0041] In a preferred embodiment, see [reference] Figure 9 , 10 The lens 5 has an outwardly extending flange 51 on its light-emitting side. The anti-glare cover 4 has an annular platform 42 on its inner circumference that abuts against the flange 51, and the anti-glare cover 4 has several second latches 43 that engage with the flange 51. During assembly, the flange 51 of the lens 5 abuts against the annular platform 42 of the anti-glare cover 4. Simultaneously, the second latches 43 engage with the flange 51 to axially limit the movement of the lens 5, ensuring its stability within the anti-glare cover 4. This snap-fit ​​assembly structure allows for quick assembly and disassembly of the lens 5, facilitating the flexible replacement of lenses with different optical parameters according to actual lighting needs, thus improving the adaptability and maintenance convenience of the luminaire.

[0042] It should be noted that the structure of the second clasp 43 is similar to that of the first clasp 41, and it is also an elastic cantilever structure. During assembly, the lens 5 is gently pressed along the axial direction, and the second clasp 43 is inserted into the flange 51 of the lens 5. During disassembly, the lens 5 is pushed out along the axial direction, and the second clasp 43 is forced to open outward and detach from the flange 51, so the lens 5 can be easily removed.

[0043] Further, see Figure 9 , 10The annular platform 42 has two symmetrically arranged notches 421, which are used to facilitate the disassembly of the anti-glare cover 4. When disassembling the anti-glare cover 4, the insertion part 301 of the U-shaped clip 30 can be directly inserted into the notch 421. The notch 421 provides a dedicated clearance space and force fulcrum for the disassembly tool, making it easy for the operator to apply external force smoothly and easily release the engagement between the anti-glare cover 4 and the mounting cavity 23, thus achieving rapid disassembly of the anti-glare cover 4.

[0044] In a preferred embodiment, see [reference] Figure 2 , 7 8. The downlight unit 10 also includes a rear cover 8, which is detachably located at the end of the heat sink 2 away from the lens 5. A wire-passing hole 81 is provided on the rear cover 8. It should be noted that a cavity 27 is provided inside the heat sink 2, located on the side of the mounting part 231 away from the mounting cavity 23. This cavity not only effectively reduces the overall weight of the heat sink 2, achieving a lightweight design for the lamp, but also provides sufficient space for the assembly and wiring of the second circuit board 61, ensuring neat installation and smooth wiring of internal electrical components. Furthermore, external power supply wires, such as drive power lines, pass through the wire-passing hole 81 into the cavity 27 to achieve electrical connection with the second circuit board 61. Alternatively, the wires electrically connected to the second circuit board 61 can be led out through the wire-passing hole 81 to the outside, achieving reliable connection with an external drive power source. By covering the opening of the cavity 27 with the rear cover 8, the second circuit board 61 and wires inside the cavity 27 of the heat sink 2 can be effectively protected, which can play a good role in dust prevention, avoid dust accumulation affecting the stability of electrical connection, and improve the working reliability and service life of the internal structure of the lamp.
