By moving the heat sink 11 to the inner side of the mounting groove 5 and making it contact with the bottom wall of the mounting groove 5, a bottom plate 3 is provided on the outer side of the bottom of the epoxy resin lens 1, and a mounting groove 5 is provided in the middle of the bottom wall of the epoxy resin lens 1.

The output shaft of the driving motor 18 is fixedly connected to the middle of the bottom wall of the fan 17. The driving motor 18 will cause the fan 17 to rotate during operation, thereby extracting heat from the bottom of the heat sink 11.

[0025] The mounting groove 5 is annular in shape, the upper side of the heat sink 11 is located inside the mounting groove 5 , and the mounting groove 5 is located inside the top of the mounting ring 9 .
