[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0027] See Figures 1 to 3 As shown, a waterproof combination downlight includes a radiator 1, a light source assembly 2 and a face ring 3. In this embodiment, the radiator is a conventional structure of the prior art and is simply applied. The radiator is provided with wires of the light source assembly, and the wires are connected to the radiator through a waterproof connector. This is a conventional operation.

[0028] In actual use, the radiator's outer wall is symmetrically provided with vertical mounting grooves 4; the inner wall of the face ring is provided with a retaining protrusion; and the bottom surface of the radiator is provided with a mounting cavity. In this embodiment, a connecting piece 5 is fixed to the outer wall of the face ring by screws, the upper portion of which is located in the vertical mounting groove and fixed by screws. The face ring and the radiator are connected by the connecting piece, and the width of the connecting piece matches the width of the vertical mounting groove. The connecting piece is a metal sheet or a plastic sheet. Different lengths of connecting pieces can be selected as needed. This structure improves installation convenience and stability, and facilitates assembly, disassembly, and maintenance operations.

[0029] During installation and use, the light source assembly is positioned within the mounting cavity and held in place by the retaining ring and the cavity's top wall. Sealing gaskets 6 are provided between the light source assembly and the inner wall of the mounting cavity, between the light source assembly and the retaining ring, and between the heat sink and the face ring. These sealing gaskets ensure a tight seal between the heat sink and the face ring, between the light source assembly and the heat sink, and between the light source assembly and the face ring, improving overall waterproof performance and enhancing applicability and practicality.

[0030] In this embodiment, the light source assembly 2 includes a base 21, a pressure cover 22, a light source frame 23, a light source body, a lamp cup 24, and a lens body. In this embodiment, the base, pressure cover, lamp cup, and lens body form an integral structure that can seal the internal light source frame and light source body, improve the sealing and waterproof properties, and help to increase the service life of the light source body. During installation, a light source cavity with an open bottom surface is provided in the base. The light source frame is fixed in the light source cavity, the light source body and lamp cup are both fixed to the light source frame, the lens body is fixed in the lamp cup, and the pressure cover is sealed and fixed to the base by an adhesive layer. The base and pressure cover are both insulating plastic structures.

[0031] The outer wall of the face ring is provided with several circular holes, within which are placed springs, marbles 7, and a pressure ring. Under the elastic force of the springs, the outer ends of the marbles extend out of the pressure ring and the outer surface of the face ring. The above structure is a conventional structure in the prior art. The marbles cooperate with the springs to mainly snap the face ring into the mounting hole, ensuring smooth and reliable installation.

[0032] In actual use, the noodle ring has symmetrically arranged shaft holes on its inner wall; a C-shaped handle 8 is provided inside the noodle ring, and both ends of the C-shaped handle can be rotated and snapped into the shaft holes. With this structure, the noodle ring can be pulled outward, and after the connecting piece is removed, the noodle ring can be pulled away from the radiator using the C-shaped handle.

[0033] The utility model has positive effects: the structure of the utility model is reasonably set up, and the face ring and the radiator are connected by a connecting piece, which is convenient for disassembly and maintenance operations, and is provided with a sealing ring, which can not only ensure the sealing of the connection between the face ring and the radiator, but also ensure the sealing between the light source assembly and the radiator, and the light source assembly and the face ring, which is conducive to improving the overall sealing and waterproof performance, and is stable and reliable to use, with strong applicability and good practicality.

[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0035] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
