At the same time, a sealing layer is formed after the white glue solidifies to seal the gap between the diffuser plate 200 and the docking ring 130, thereby improving the sealing performance between the heat dissipation shell 100 and the diffuser plate 200.

[0037] Please refer to Figure 3 , Figure 4 and Figure 7 , the waterproof silicone plug 600 is soft in texture and will deform when subjected to external pressure. The waterproof silicone plug 600 is provided with a through hole 610 and a U-shaped groove 620. The waterproof silicone plug 600 is arranged in the mounting groove 120. There is an interference fit between the waterproof silicone plug 600 and the mounting groove 120. The U-shaped groove 620 is buckled with the docking ring 130. The end of the power cord 500 is provided with a plug 510. The plug 510 passes through the through hole 610 and is electrically connected to the LED lamp board 400.

[0038] Please refer to Figure 3 and Figure 6 and Figure 7, the face ring 300 covers the heat dissipation shell 100. There is a protrusion 310 on the face ring 300, and the protrusion 310 is embedded in the installation groove 120. The face ring 300 and the heat dissipation shell 100 are locked together by screws. After fixing the face ring 300, the protrusion 310 presses the waterproof silicone plug 600 and the plug connector 510.
