[0007] The decorative ring is provided with a detachable buckle, and the decorative ring is snapped into the slot of the radiator through the detachable buckle.

[0008] In one embodiment, the detachable buckle includes an elastic root and a clamping head connected to the end of the root, the clamping head is clamped into the clamping slot, and the surface of the clamping head that cooperates with the clamping slot is an inclined surface.

[0009] In one embodiment, the downlight further comprises:

[0010] A light board, the light board is arranged at the bottom of the inner cavity of the radiator;

[0011] Reflective paper, the reflective paper cover is arranged on the light-emitting surface of the light board;

[0012] An optical sheet is located between the reflective paper and the decorative ring, and the decorative ring presses and fixes the optical sheet and the reflective paper onto the heat sink.

[0013] In one embodiment, the reflective paper is made by integrated blister forming.

[0014] In one embodiment, a brim is provided at one end of the reflective paper close to the optical sheet, and the optical sheet and the heat sink clamp the brim.

[0015] In one embodiment, the optical sheet is a sheet-shaped Fresnel lens.

[0016] In one embodiment, screw posts for fixing the power cord and the lamp panel are both disposed in the inner cavity of the heat sink.

[0017] In one embodiment, a spring clip is further included, and the spring clip is arranged outside the heat sink.

[0018] One or more of the above technical solutions in the embodiments of the present utility model have at least the following technical effects or advantages:

[0019] The downlight provided by the embodiment of the utility model uses a detachable buckle on the decorative ring to connect with the slot on the inner cavity of the heat sink, so that the user can easily replace the decorative ring with different colors, thereby achieving a personalized decorative effect of the downlight. This design not only meets the user's diverse needs for the appearance of the downlight, but also improves the market competitiveness of the product.

[0020] Secondly, the design of the detachable buckle makes the replacement process of the decorative ring simple, fast and safe. Users can easily replace the decorative ring without complicated operations, which not only improves the user experience, but also reduces the potential risks caused by replacing the decorative ring.

[0035] See also Figures 1 to 3 The embodiment of the present application provides a downlight, comprising a heat sink 1 and a decorative ring 2. The heat sink 1 is provided with an inner cavity for accommodating a lamp assembly, and a slot 11 is provided on the cavity wall of the inner cavity; a detachable buckle 21 is provided on the inner cavity, and the decorative ring 2 is snapped into the slot 11 of the heat sink 1 through the detachable buckle 21.

[0036] In one embodiment, the detachable buckle 21 includes an elastic root 211 and a clamping head 212 connected to the end of the root 211. The clamping head 212 is inserted into the slot 11, and the surface of the clamping head 212 that matches the slot 11 is an inclined surface.

[0037] like Figure 3 As shown, when the decorative ring 2 needs to be replaced, it is only necessary to give an upward force to the decorative ring 2 to separate the decorative ring 2 from the radiator 1. Under the action of this force, the reaction force given to the clamping head 212 by the clamping slot 11 will generate an inward component force, thereby causing the elastic root 211 to deform and bend elastically, thereby causing the clamping head 212 to disengage from the clamping slot 11, and then remove the decorative ring 2 from the radiator 1. Similarly, when a new decorative ring 2 needs to be installed on the radiator 1, it is only necessary to align the decorative ring 2 with the radiator 1 and press the decorative ring 2 downward with force, so that the decorative ring 2 can be clamped into the clamping slot 11, thereby realizing quick and convenient disassembly and assembly of the decorative ring 2.

[0038] In one embodiment, the downlight further comprises a lamp board 3, a reflective paper 4, and an optical sheet 5. The lamp board 3 is arranged at the bottom of the inner cavity of the heat sink 1; the reflective paper 4 is covered on the light-emitting surface of the lamp board 3; the optical sheet 5 is located between the reflective paper 4 and the decorative ring 2, and the decorative ring 2 presses and fixes the optical sheet 5 and the reflective paper 4 to the heat sink 1.

[0039] In one embodiment, the reflective paper 4 is made by integrated blister molding. The reflective paper 4 made by integrated blister molding has no joint seams. Compared with the reflective paper 4 made by conventional punching, the reflective paper 4 in this embodiment has no joint seams, thereby making the downlight more beautiful.

[0040] like Figure 2As shown, in one embodiment, a brim 41 is provided at one end of the reflective paper 4 close to the optical sheet 5, and the optical sheet 5 and the heat sink 1 clamp the brim 41. The brim 41 is clamped to the step surface of the inner cavity of the heat sink 1 through the optical sheet 5, so that the reflective paper 4 can be used in conventional and waterproof versions of downlights.

[0041] In one embodiment, the optical sheet 5 is a sheet-shaped Fresnel lens. The optical sheet 5 adopts a sheet-shaped Fresnel lens design solution, which can replace the traditional reflector cup or lens, so that the light source does not need to be hidden deep to achieve the anti-glare effect, thereby reducing the overall height of the lamp and saving production costs.

[0042] like Figure 5 As shown, in one embodiment, the screw column 31 for fixing the power line 8 and the lamp board 3 is arranged in the inner cavity of the heat sink 1. Figure 5 The wire pressing seat 71 and the screw column 31 are arranged in the inner cavity of the radiator 1), so that there is no screw column 31 on the back of the radiator 1, thereby improving the overall aesthetics of the downlight.

[0043] In one embodiment, a spring clip 6 is further included, and the spring clip 6 is arranged outside the heat sink 1. The spring clip 6 is arranged to facilitate the installation and fixation of the downlight.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
