Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] See Figures 1 to 5 As shown, a retractable downlight includes a face ring 1 and a lamp body 2. The lamp body includes a cylindrical lamp housing 21, a cylindrical lamp holder 22, a light source plate 23, a lamp cup 24, an annular lamp shade holder 25, and an anti-glare lamp shade 26. In this embodiment, the cylindrical lamp housing is connected to the face ring. During installation, the cylindrical lamp holder is retractably disposed inside the cylindrical lamp housing. In practical applications, the face ring, cylindrical lamp housing, cylindrical lamp holder, and annular lamp shade holder are all aluminum or plastic structures.

[0031] Furthermore, a partition is fixed to the middle of the inner wall of the cylindrical lamp holder, and the light source plate is fixed to the bottom surface of the partition. An internal thread 3 is provided on the bottom of the inner wall of the cylindrical lamp holder, and an external thread 4 is provided on the outer wall of the annular lampshade holder. During assembly, the anti-glare lampshade is fixed inside the annular lampshade holder, which is threadedly connected to the cylindrical lamp holder. The lamp cup is positioned between the annular lampshade holder and the partition, and the light from the light source plate shines outward from the anti-glare lampshade after passing through the lamp cup. This structure allows for the assembly and disassembly of the face ring and the cylindrical lamp housing, as well as the assembly, disassembly, and telescopic adjustment of the cylindrical lamp holder and the cylindrical lamp housing. It also facilitates the assembly and disassembly of the annular lampshade holder and the cylindrical lamp holder, making it easier to disassemble and maintain different components, reducing the difficulty of assembly and disassembly, improving assembly efficiency, and offering strong applicability.

[0032] In this embodiment, the top of the cylindrical lamp holder is provided with a universal ball joint 5 and a pressure ring 6. The pressure ring is threadedly connected to the top of the cylindrical lamp holder, and the universal ball joint is limited by the pressure ring. Furthermore, the wires of the light source board pass through the universal ball joint and extend out of the top of the cylindrical lamp housing to connect with an external power source. When the universal ball joint is not fixed to the cylindrical lamp housing, the cylindrical lamp holder can be pulled outward from inside the cylindrical lamp housing.

[0033] In some other embodiments, the top of the universal ball joint is provided with a mounting screw hole 7; the cylindrical lamp holder retracts upward into the cylindrical lamp housing, and the top of the universal ball joint is connected by a hollow screw; and the wire passes through the middle screw. Through the above structure, the connection can be achieved via the hollow screw, and the effectiveness of the telescopic adjustment can be guaranteed.

[0034] In this embodiment, an anti-glare mesh plate 8 is provided inside the annular lampshade holder, and the anti-glare mesh plate is positioned above the anti-glare lampshade. The anti-glare effect can be improved by using the anti-glare mesh plate in conjunction with the anti-glare lampshade.

[0035] In this embodiment, the diameter of the cylindrical lamp holder is smaller than the inner diameter of the cylindrical lamp housing. This allows the cylindrical lamp holder to be adjusted within a small range of angles within the cylindrical lamp housing, meeting lighting needs in various situations.

[0036] In this embodiment, the face ring is threaded, snap-fitted, or locked in place with screws to the cylindrical lamp housing. Assembly can be performed as needed, improving the convenience and stability of the connection.

[0037] Furthermore, mounting springs 9 are fixed to the symmetrical sides of the face ring by screws, facilitating installation and use.

[0038] This utility model has positive effects: The structure of this utility model is reasonably designed. Its lamp body includes a cylindrical lamp shell, a cylindrical lamp holder, a light source plate, a lamp cup, a ring-shaped lamp shade holder, and an anti-glare lamp shade. The cylindrical lamp shell is connected and positioned with the face ring, and the cylindrical lamp holder is located inside the cylindrical lamp shell. At the same time, the ring-shaped lamp shade holder is located inside the cylindrical lamp holder, which facilitates disassembly and maintenance operations, improves the convenience and effectiveness of assembly, and the anti-glare lamp shade also helps to improve the anti-glare performance, making it highly applicable.

[0039] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
