The elastic tension of the elastic gasket on the heat sink increases, making the heat sink securely fastened to the face ring. In addition, since the elastic gasket does not occupy space in the width of the heat sink, it better ensures the light output effect of the fastening type lamp. Attached Figure Description

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0035] A snap-on light fixture is provided. The snap-on light fixture includes a heat sink, a face ring, and a resilient gasket. The heat sink is detachably connected to the face ring, and the face ring is at least partially stopped on the heat sink when connected to the heat sink. The resilient gasket is disposed around a circumference of the face ring, the resilient gasket is sandwiched between the face ring and the heat sink when the face ring is connected to the heat sink, and the resilient gasket is configured to at least partially deform into a convex shape, and the convex shape has a smaller curvature when sandwiched by the face ring and the heat sink.

[0036] The above-mentioned buckling type lamp makes the heat sink at least partially stop on the heat sink when connected to the heat sink, that is, the buckling is achieved by the face ring and the heat sink itself, the structure is relatively simple, and the installation and disassembly convenience is relatively high. Further, the elastic gasket is arranged around the circumference of the face ring, and the elastic gasket is clamped between the face ring and the heat sink when the face ring is connected to the heat sink, that is, the elastic gasket is arranged on the face ring. When the face ring and the heat sink are connected, the elastic gasket is clamped between the face ring and the heat sink. The elastic gasket is configured to at least partially deform in a convex structure, and the curvature of the deformed structure decreases when clamped by the face ring and the heat sink. That is, during the process of buckling the heat sink to the face ring, the heat sink continuously gives pressure to the elastic gasket, and the pressure increases smoothly. The installation is smooth, and the elastic gasket is elastically deformed during this process to reduce the curvature of the convex deformed structure. The elastic gasket increases the elastic tension of the heat sink to stably buckle the heat sink to the face ring. In addition, since the elastic gasket does not occupy the space on the width of the heat sink, the light output effect of the buckling type lamp is better ensured.

[0037] In order to better understand the buckling type lamp of the present application, the buckling type lamp of the present application is further explained as follows:

[0038] Please refer to Figures 1 to 4 The buckling type lamp 10 of an embodiment includes a heat sink 100, a face ring 200, and an elastic gasket 300. The heat sink 100 is detachably connected to the face ring 200, and the face ring 200 is at least partially stopped on the heat sink 100 when connected to the heat sink 100. The elastic gasket 300 is arranged around the circumference of the face ring 200, the elastic gasket 300 is clamped between the face ring 200 and the heat sink 100 when the face ring 200 is connected to the heat sink 100, and the elastic gasket 300 is configured to at least partially deform in a convex structure, and the curvature of the deformed structure decreases when clamped by the face ring 200 and the heat sink 100.

[0039] The buckle type lamp 10 described above makes the heat sink 100 at least partially stop on the heat sink 100 when connected to the heat sink 100, that is, the buckle is achieved by the face ring 200 and the heat sink 100 itself, the structure is relatively simple, and the installation and disassembly convenience is relatively high. Further, the elastic gasket 300 is arranged around the circumference of the face ring 200, the elastic gasket 300 is clamped between the face ring 200 and the heat sink 100 when the face ring 200 is connected to the heat sink 100, that is, the elastic gasket 300 is arranged on the face ring 200, and when the face ring 200 and the heat sink 100 are connected, the elastic gasket 300 is clamped between the face ring 200 and the heat sink 100. The elastic gasket 300 is configured to at least partially deform in a convex shape, and the curvature of the deformed structure decreases when the face ring 200 and the heat sink 100 are clamped. That is, during the process of buckling the heat sink 100 to the face ring 200, the heat sink 100 constantly gives pressure to the elastic gasket 300, and the pressure increases smoothly, the installation smoothness is better, and the process promotes the elastic deformation of the elastic gasket 300 to cause the curvature of the convex deformed structure to decrease, and the elastic tension of the elastic gasket 300 on the heat sink 100 increases to make the heat sink 100 buckle on the face ring 200 stably. In addition, since the elastic gasket 300 does not need to occupy the space on the width of the heat sink 100, the light output effect of the buckle type lamp 10 is better ensured.

[0040] It can be understood that part of the gasket deforms and bends, and the bent part is convex relative to the whole gasket. The part that is convex is the convex deformed structure. The convex deformed structure and the remaining part of the gasket together constitute the elastic gasket. When the elastic gasket is subjected to pressure from the heat sink, the elastic gasket deforms elastically to cause the convex deformed structure to deform elastically and the curvature to decrease. Further, after the pressure from the heat sink is removed, the elastic deformation of the convex deformed structure of the elastic gasket disappears and the curvature is restored.

[0041] Please refer to Figures 2 to 4 In one embodiment, at least one positioning groove 201 is arranged on the outer wall of the face ring 200, and the elastic gasket 300 is at least partially inserted into the positioning groove 201 and slidably arranged in the positioning groove 201 along the circumference of the face ring 200.

[0043] Further, please refer to Figures 3 to 5 , the elastic gasket 300 is an elastic washer. Further, the elastic gasket 300 is provided with a fracture 301, so that the radius of the elastic gasket 300 is variable, so that the elastic gasket 300 can be easily removed from the face ring 200, on the one hand, the disassembly convenience of the elastic gasket 300 is improved, on the other hand, the stable setting of the elastic gasket 300 on the face ring 200 is ensured.

It can be understood that the protruding part 320 is a protruding deformation structure on the elastic gasket, and the arrangement of the protruding part 320 preferably ensures the effective elastic retention of the elastic gasket 300 to the heat sink 100, so that the heat sink 100 is stably stopped on the face ring 200, thereby preferably ensuring the stability of the connection between the heat sink 100 and the face ring 200.

[0050] Further, the plurality of protruding parts are evenly spaced on the main part along the circumference of the surface ring.
