[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] This embodiment is a downlight with high waterproof and heat dissipation performance, such as Figures 1 to 6 As shown, it includes a heat sink 1, a light source assembly 2 and a diffusion assembly 3 in sequence. The light source assembly 2 is detachably connected to the heat sink 1, and the diffusion assembly 3 is rotatably connected to the heat sink 1.

[0028] The radiator 1 includes a radiator tube 101 and a heat sink mounted on top of the radiator tube 101. The radiator comprises a star-shaped radiator 10 and an annular radiator 11. Mounting springs 12 for mounting the downlight are provided on each of the star-shaped radiator 10 and the annular radiator 11. The mounting springs 12 on the star-shaped radiator 10 are positioned between adjacent fins 102. Mounting posts 103 are provided on two adjacent fins 102, and the mounting springs 12 are mounted on these posts. The mounting springs 12 on the annular radiator 11 are mounted on the radiator tube 101. A mounting base 104 is provided on the radiator tube 101, and the mounting springs 12 are mounted on these bases. By providing the star-shaped radiator 10 and the annular radiator 11, the appropriate radiator type can be selected based on different usage environments and requirements, thereby increasing the practicality of the downlight.

[0029] Furthermore, a waterproof connector assembly 13 is provided at the top of the radiator 1, and an external controller is connected to the light source assembly 2 through the waterproof connector assembly 13, thereby controlling the light source assembly 2. The waterproof connector assembly 13 includes a connector cap 131, a rubber plug 132, a connector seat 133, and a rubber ring 134, wherein the connector cap 131, the rubber plug 132, and the connector seat 133 are all hollow structures, which facilitates the smooth passage of the controller's circuit to connect to the light source assembly 2. The connector cap 131 is provided at the top of the connector seat 133, the rubber ring 134 is provided at the bottom of the connector seat 133, and the rubber plug 132 is sleeved inside the connector seat 133. The rubber ring 134 is provided at the bottom of the connector seat 133. When the connector seat 133 is installed at the top of the radiator tube 101, the rubber ring 134 can effectively seal the connection between the connector seat 133 and the top of the radiator 1, preventing moisture from entering the interior of the downlight from the outside, thereby ensuring the waterproof performance of the downlight when used in a humid environment or outdoors. Since the rubber plug 132 is sleeved in the connector seat 133 , when the external controller line passes through, the rubber plug 132 can prevent moisture on the controller line from entering the downlight from the inside, further enhancing the waterproof effect.

[0030] Furthermore, the light source assembly 2 is disposed within the heat sink tube 101 and includes a lens plate 20 and an LED light board 21. A raised annular cone 201 is provided on the top of the lens plate 20, forming a storage slot between the annular cone 201 and the top of the lens plate 20. The LED light board 21 is disposed within the storage slot. A plurality of retaining posts 2011 extend from the inner side of the annular cone 201. The LED light board 21 is provided with a plurality of grooves 211, which correspond to the retaining posts 2011 and are engaged with the retaining posts 2011. By providing the retaining posts 2011 on the inner side of the annular cone 201, when the LED light board 21 is placed in the storage slot, the retaining posts 2011 will restrict the LED light board 21, preventing it from shaking under the action of external forces.

[0031] Furthermore, a waterproof rubber ring 4 is provided between the light source assembly 2 and the heat sink 1. The waterproof rubber ring 4 is embedded in the top of the annular cone 201. Specifically, an embedding groove 2012 is provided in the top of the annular cone 201, and the depth of the embedding groove 2012 is less than the thickness of the waterproof rubber ring 4 in a compressed state. By providing the waterproof rubber ring 4, when the light source assembly 2 and the heat sink 1 are connected, the waterproof rubber ring 4 can form a waterproof barrier between the light source assembly 2 and the heat sink 1, thereby improving the waterproof performance of the downlight. The depth of the embedding groove 2012 is less than the thickness of the waterproof rubber ring 4 in a compressed state, which means that during the installation process, the waterproof rubber ring 4 will be compressed and produce a certain degree of elastic deformation, thereby fitting more tightly between the embedding groove 2012 and the heat sink 1, further enhancing the waterproof performance of the downlight.

[0032] Furthermore, the diffusion assembly 3 includes an inner diffusion cover 301, a reflective cup 31, a diffuser plate 32 and a surface ring 33 in sequence, wherein the inner diffusion cover 301 is arranged in the reflective cup 31 and is clamped with the reflective cup 31. Specifically, a boss is provided on the inner side of the reflective cup 31, and a plastic hook is provided on the outer side of the inner diffusion cover 301, which is clamped with the boss. The diffuser plate 32 is located below the reflective cup 31, and the surface ring 33 is located below the diffuser plate 32. The surface ring 33 includes an integrally formed first ring body 331 and a second ring body 332, wherein the second ring body 322 is located below the first ring body 331, and is used to support the diffuser plate 32 and the reflective cup 31 to prevent the reflective cup 31 and the diffuser plate 32 from falling off from the surface ring 33.

[0033] Furthermore, the face ring 33 is rotatably engaged with the bottom of the radiator tube 101, and a plurality of spaced-apart mounting platforms 3311 extend from the inner side of the first ring body 331. The plurality of mounting platforms 3311 are perpendicular to the first ring body 331. A plurality of spaced-apart arc-shaped platforms 105 are provided at the bottom of the radiator tube 101. The arc-shaped platforms 105 are rotatably engaged with the bottom of the mounting platforms 3311. The mounting platforms 331 and the arc-shaped platforms 105 are mutually engaged. The face ring 33 can be connected to the radiator tube 101 by rotating it, which makes disassembly and assembly more convenient, facilitates daily maintenance and replacement, and improves work efficiency.
