[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See Figures 1 to 4 As shown, the ceiling light face ring quick-change structure includes a light body assembly A and a zoom lens 4. The light body assembly A contains a light-emitting element, and the zoom lens 4 is located at the bottom of the light body assembly A and below the light-emitting element. It also includes a face ring 7, with a lower connecting ring 71 extending from the face ring 7. The lower connecting ring 71 is provided with a screw-fitting part 8. The light body assembly A has an upper connecting ring 21 that is nested and fitted with the lower connecting ring 71. The upper connecting ring 21 is provided with a screw-fitting part 9. Through the cooperation of the screw-fitting part 9 and the screw-fitting part 8, the face ring 7 can be quickly and easily connected to the bottom of the light body assembly A.

[0022] This ceiling light features a quick-change structure that allows the face ring to be replaced, enabling assemblers to replace the round face ring with a square face ring according to the actual situation. It has the advantages of modular products, and the face ring is easy and quick to install and remove without the need for secondary fasteners, resulting in high assembly efficiency.

[0023] Specifically: the screw-fit component 8 includes several screw-fit protrusions 81, which are evenly distributed circumferentially on the inner wall surface of the lower connecting ring 71; the screw-fit part 9 includes several rotating fastening grooves 91 corresponding to the number of screw-fit protrusions 81, which are evenly distributed circumferentially on the outer wall surface of the upper connecting ring 21, and the screw-fit protrusions 81 and the rotating fastening grooves 91 are rotatably fastened together; the assembly and disassembly are achieved through rotational fastening, which can improve the connection strength of the face ring 7, make the connection stable and reliable, easy to install and disassemble, and have high assembly efficiency.

[0024] The rotating fastening groove 91 includes a spiral support surface 92 and a fastening inlet / outlet 93 for the rotating fastening protrusion 81 to enter the rotating fastening groove 91. The spiral support surface 92 is provided with a locking protrusion 94 on the side facing the fastening inlet / outlet 93. The top surface of the locking protrusion 94 is inclined along the direction of the spiral support surface 92. Since the spiral support surface 92 is inclined, the face ring 7 can be gradually tightened during the screwing process. However, when subjected to the opposite force, the face ring 7 is prone to detach from the fastening inlet 93. Therefore, the locking boss 94 can limit the screwing protrusion 81 to prevent the screwing protrusion 81 from falling into the fastening inlet 93.

[0025] The bottom of the face ring 7 is integrally connected to a panel 72, which has a circular or square ring structure; this allows the panel 72 to be modularized, and different shapes of panels 72 can be assembled on the ceiling light according to different needs.

[0026] It also includes two sets of spring clips 10, each spring clip 10 having a connecting through hole 1001. Two mounting seats 73 are provided on opposite sides of the outer ring 7. Each mounting seat 73 has a threaded hole 731 corresponding to the connecting through hole 1001. By passing a screw through the connecting through hole 1001 and the threaded hole 731, the spring clips 10 and the ring 7 are assembled and connected. The spring clip 10 of this structure can be disassembled and assembled by fastening, allowing the face ring 7 to be manufactured separately, and one of the spring clips 10 can be easily disassembled and replaced if it is damaged.

[0027] The connecting through hole 1001 is a strip-shaped hole that extends along the axial direction of the face ring 7. The strip-shaped connecting through hole 1001 cooperates with the screw, allowing the spring clip 10 to be adjusted up and down to further adapt to the thickness of the ceiling.

[0028] The spring clip 10 includes an upper spring clip 11 and a lower spring clip 12, which are hinged to each other by a spring pin 13. A spring 14 is also sleeved on the spring pin 13, and the two ends of the spring 14 act on the upper spring clip 11 and the lower spring clip 12 respectively. The connecting through hole 1001 is formed on the lower spring clip 12. This structure of the spring clip 10 is prior art and will not be described in detail here. However, the difference lies in the fact that the lower spring clip 12 has inwardly bent flanges on both sides, which form guide rails 121. As flanges, they can improve the strength of the lower spring clip 12 and make it less prone to deformation and bending. The mounting base 73 is provided with guide grooves 732 at intervals corresponding to the width of the two guide rails 121. Through the sliding cooperation of the guide grooves 732 and the guide rails 121, the vertical up and down sliding of the spring clip 10 is restricted. This allows the spring clip 10 to slide vertically when adjusting its position without any offset sliding, ensuring that the connecting through hole 1001 is kept in correspondence with the threaded hole 731.

[0029] The lamp body assembly A includes a heat dissipation base 1 connected to the light-emitting body, a lamp housing 2 forming a lower connecting ring 71, and a sliding sleeve 3. The heat dissipation base 1 is connected to the rear end of the lamp housing 2, the sliding sleeve 3 is slidably nested inside the lamp housing 2, the zoom lens 4 is fixed to the bottom of the sliding sleeve 3, and the face ring 7 is quickly and easily connected to the bottom end of the lamp housing 2 and has a support surface 701 located below the sliding sleeve 3.

[0030] The lamp body assembly A of this structure can move up and down by driving the sliding sleeve 3, thereby moving the zoom lens 4 away from or closer to the light source, thus adjusting the size of the light spot and the light diffusion range of the light emitted by the light source.

[0031] See Figure 5 As shown, the zoom lens 4 includes a plano-convex lens 41 and a light-transmitting lampshade 42 integrated with the plano-convex lens 41. The light-transmitting lampshade 42 is placed on the sliding sleeve 3. This allows the zoom lens 4 to also function as a lampshade, which can reduce the number of assembly parts and improve production efficiency. In addition, the light-transmitting lampshade 42 also has the function of refracting light, which can increase the light diffusion range.

[0032] The plano-convex lens 41 has honeycomb-shaped protrusions 411 on its flat surface; this structure makes each honeycomb-shaped protrusion 411 act as a convex lens, making the light more focused.

[0033] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
