Description

Technical Field

[0001] This utility model belongs to the field of downlight technology, and in particular relates to a downlight that is easy to assemble and disassemble. Background Technology

[0002] Downlights, as highly directional lighting devices, are widely used in commercial displays, art gallery lighting, architectural accent lighting, and home ambiance creation. In different application environments, it is often necessary to replace optical components (such as focusing lenses, floodlight reflectors, honeycomb anti-glare mesh, and diffusers) to adjust the beam angle, optimize the light spot shape, or control glare to meet diverse lighting needs. However, in current technology, downlights are primarily assembled using screws. This necessitates the use of a screwdriver to remove screws and replace the required optical components each time they are replaced. Finally, the removed screws must be tightened again to secure the optical components. This results in a multi-step mechanical operation that takes several minutes, failing to meet the needs of scenarios requiring rapid adjustments, such as exhibition setups and stage lighting.

[0034] Example 1

[0035] See Figures 1-9This utility model provides an easy-to-assemble and disassemble downlight, including a lamp housing 1, a heat sink 2, a light-emitting component 3, and a lens front cover 4. The lamp housing 1 is provided with a first engaging tooth 11 and a second engaging tooth 12. A limiting ring 13 is also provided on the inner side wall of the lamp housing 1 between the first engaging tooth 11 and the second engaging tooth 12. The heat sink 2 is located on the upper end face of the lamp housing 1 and has a cavity 25 inside. A first locking guide rail 21 is provided on the outer side wall of the heat sink 2 near the lamp housing 1. The first engaging tooth 11 cooperates with the first locking guide rail 21, and the thickness of the first locking guide rail 21 is less than the vertical distance between the two opposing tooth surfaces of the first engaging tooth 11. This design not only ensures the quick cooperation between the first engaging tooth 11 and the first locking guide rail 21, but also allows the first engaging tooth 11 and the first locking guide rail 21 to lock each other through relative rotation after cooperation.

[0036] The light-emitting component 3 is disposed within the cavity 25 of the heat sink 2. The light-emitting component includes a lamp plate 31, a reflector 32, and a lens 33. The lens front cover 4 is disposed inside the lamp housing 1. A second locking guide rail 421 is provided on the outer side wall of the lens front cover 4. The second engaging tooth 12 engages with the second locking guide rail 421. The thickness of the second locking guide rail 421 is less than the vertical distance between the two opposing tooth surfaces of the second engaging tooth 12. This design not only ensures the rapid engagement of the second engaging tooth 12 with the second locking guide rail 421, but also allows the second engaging tooth 12 and the second locking guide rail 421 to lock each other through relative rotation after engagement. The first locking guide rail 21 and the second locking guide rail 421 are respectively arranged in an arc shape along the outer side wall of the heat sink 2 and the lens front cover 4.

[0037] In this embodiment, a first locking guide rail 21 is provided on the outer wall of the heat sink 2 near the end of the lamp housing 1, and a second locking guide rail 421 is provided on the outer wall of the lens front cover 4. The first locking guide rail 21 and the second locking guide rail 421 are respectively arranged in an arc shape on the outer walls of the heat sink 2 and the lens front cover 4. A first engaging tooth 11 and a second engaging tooth 12 are provided on the lamp housing 1. The first engaging tooth 11 cooperates with the first locking guide rail 21, and the second engaging tooth 12 cooperates with the second locking guide rail 421. The light-emitting component 3 is placed inside the heat sink 2. Locking or unlocking can be completed by simply rotating the lamp body component.

[0038] The first engaging tooth 11 is located on the inner sidewall of the lamp housing 1 near the end of the heat sink 2, and the second engaging tooth 12 is located on the inner sidewall of the lamp housing 1 away from the first engaging tooth 11. A plurality of the first engaging teeth 11 and the second engaging teeth 12 are circumferentially distributed on the lamp housing 1, and the first engaging teeth 11 and the second engaging teeth 12 are spaced apart from each other in the circumferential direction of the lamp housing 1. By spaced apart from each other in the circumferential direction of the lamp housing 1, the uniformity of force on each part of the heat sink 2 and the lens front cover 4 after they are engaged with the lamp housing 1 can be better ensured, as well as the reliability of the overall connection of the downlight.

[0039] The lens front cover 4 includes a straight cylindrical portion 41, a conical portion 42, and an annular portion 43. The straight cylindrical portion 41 is located at the upper end of the conical portion 42, and the annular portion 43 is located at the end of the conical portion 42 away from the straight cylindrical portion 41. The straight cylindrical portion 41, the conical portion 42, and the annular portion 43 are integrally formed. The second locking guide rail 421 is located on the conical portion 42, and the second locking guide rail 421 is also provided with an anti-detachment plate 422 at the end near the annular portion 43. The anti-detachment plate 422 is designed to prevent the lens front cover 4 from falling off during the use of the spotlight.

[0040] The inner wall of the straight cylindrical part is provided with protrusions 411, and a plurality of protrusions 411 are distributed circumferentially along the inner wall of the straight cylindrical part 41. An abutment platform 412 is provided on the inner wall of the straight cylindrical part 41 at the position where it contacts the conical part 42. The end face of the protrusion 411 near the abutment platform 412 is a horizontal surface, which is used to abut against the end of the reflector cup 32 near the light emission direction. The other side is inclined, which can better ensure that the horizontal surface can withstand the normal force.

[0041] The reflector cup 32 is provided with a third locking guide rail 321 at one end along the light emission direction. The two ends of the third locking guide rail 321 are at different heights in the vertical direction. The number of the third locking guide rails 321 is the same as the number of the protrusions 411 on the straight cylindrical part 41. The protrusions 411 cooperate with the third locking guide rails 321 to lock the reflector cup 32.

[0042] In this embodiment, the top of the heat sink 2 is provided with a dimming controller 7 and a wiring hole 23. The inner wall of the cavity 25 is provided with a protrusion 26 at one end along the light emission direction. The dimming controller 7 is electrically connected to the lamp board 31. The top of the heat sink 2 integrates the dimming controller 7 and is electrically connected to the lamp board 31 to achieve precise control of light effect. The power cord passes through the wiring hole 23 and is electrically connected to the lamp board 31. The lamp board 31 is fixed to the cavity 25 of the heat sink 2 by screws. A heat sink 22 is also provided on the top of the outer side of the heat sink 2 to better dissipate the heat generated on the lamp board 31 to the external environment in a timely manner through several heat sinks 22, thereby improving the service life of the downlight. A positioning mark 24 is also provided on the heat sink 2 at the upper end of the starting end of the first locking guide rail to enable quick initial positioning when installing the heat sink 2, thereby improving the replacement speed of optical components.

[0043] A first silicone ring 5 is provided on the outer side wall of the lens front cover 4 near the end of the straight cylindrical part 41. A convex ring 51 is provided on the outer side wall of the first silicone ring 5. The end face of the convex ring 51 near the heat sink 2 abuts against the boss 26 of the heat sink 2, and the other end face of the convex ring 51 abuts against the limiting ring 13. The design of the first silicone ring 5 and the convex ring 51 realizes the compression and sealing between the lamp housing 1 and the heat sink 2, which not only makes the downlight have a certain degree of waterproofness, but also generates relative rotational damping between the lamp housing 1 and the heat sink 2, thus better ensuring the stability of the downlight connection.

[0044] Lens 33 is mounted on the abutment platform 412. The end face of lens 33 near the lamp plate 31 abuts against the end of reflector 32 along the light emission direction. A second silicone ring 6 is also provided on the abutment platform 412. Lens 33 is placed on the second silicone ring 6. The second silicone ring 6 not only ensures the sealing of the connection between lens 33 and lens front cover 4, but also generates damping when lens 33 and reflector 32 rotate relative to lens front cover 4, improving the stability of the connection. Reflector 32 is rotated and engaged with the protrusion 411 of the straight cylindrical part 41 of lens front cover 4 through the third locking guide rail 321, so that reflector 32, lens 33 and lens front cover 4 form a pre-assembled module. When replacing, the whole assembly is disassembled and assembled to avoid the components from falling apart. The diameter of the conical opening of reflector 32 near lens 33 is the same as the diameter of the conical opening of the conical part 42 of lens front cover 4 near lens 33.

[0045] The outer wall of the lamp housing 1 is provided with a pair of spring clips 8 for installing and positioning the downlight.

[0046] Specifically, when optical components need to be replaced, first locate the positioning mark 24. Hold the lamp housing 1 with one hand and rotate the heat sink 2 with the other hand to rotate the positioning mark 24 towards the spring buckle 8, separating the first locking guide rail 21 from the first engaging tooth 11, thereby removing the heat sink 2. Then, rotate the reflector cup 32 and the lamp housing 2 relative to each other, separating the protrusion 411 from the third locking guide rail 321, thereby removing the reflector cup 32 and the lens 33. Finally, rotate the lens front cover 4 and the lamp housing 1 relative to each other, separating the first locking guide rail 421 from the first engaging tooth 12, thus separating the lamp housing 1 and the lens front cover 4. Then, depending on the actual needs, replace different types of focusing lenses / reflectors, or replace the lens with optical components such as honeycomb anti-glare mesh / soft light diffuser. Finally, quickly assemble the downlight according to the reverse process of disassembly. This design solves the efficiency bottleneck of frequently replacing optical components in exhibition setup, stage lighting and other scenarios, reduces labor and time costs, and maintains the reliability and sealing of the structure.

[0047] The above description is merely a specific embodiment of this utility model. Those skilled in the art will understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.
