[0020] Specifically, the protection mechanism 4 includes a second waterproof breathable membrane 401 and a shielding mesh plate 402 , and the second waterproof breathable membrane 401 and the shielding mesh plate 402 are sequentially installed on the upper inner wall of the groove 3 from top to bottom.
[0021] In this embodiment, the second waterproof breathable membrane 401 and the shielding mesh plate 402 prevent external dust and rainwater from entering, while increasing the anti-interference function.
[0022] Specifically, the shielding mesh plate 402 and the shielding mesh tube 7 are both woven from tinned soft copper wires, and the mesh diameters of the shielding mesh plate 402 and the shielding mesh tube 7 are 0.3 mm-0.5 mm.
[0023] In this embodiment, the shielding mesh plate 402 and the shielding mesh tube 7 have anti-interference function and dustproof function.
[0024] Specifically, the heat dissipation mechanism 9 includes a thermally conductive sleeve 901, heat dissipation fins 902 and a second air hole 903. The thermally conductive sleeve 901 is threadedly installed in the ceramic substrate 1. The inner wall of the thermally conductive sleeve 901 is in contact with the outer surface of the shielding mesh tube 7. The outer surface of the thermally conductive sleeve 901 is evenly installed with heat dissipation fins 902 along the circumferential direction, and the second air hole 903 is opened on the thermally conductive sleeve 901 between adjacent heat dissipation fins 902.
[0025] In this embodiment, the heat-conducting sleeve 901 and the heat-dissipating fins 902 enable the heat generated by the LED lamp wick 2 to be quickly discharged, and the second air holes 903 allow external air to enter the LED lamp wick 2 .
[0026] Specifically, a threaded sleeve 11 for threaded connection of the heat-conducting sleeve 901 is fixedly embedded on the upper surface of the ceramic substrate 1 corresponding to the heat-conducting sleeve 901 .

At the same time, the heat dissipation mechanism 9 and the transparent cover 10 can be disassembled, which is convenient for subsequent maintenance of the LED lamp beads and reduces the cost of use.
