[0025] Specifically, when the lens 5 needs to be installed, the operator first aligns the sliding bars 10 on both sides of the top of the lens 5 with the sliding grooves 11 on both sides of the bottom of the lamp box 1, and then pushes the lens 5 into the lamp box 1 along the sliding grooves 11. At this time, the fixed bars 13 inside the mounting blocks 4 on both sides of the lens 5 are aligned with the limiting holes on both sides of the lamp box 1 and are clamped into the limiting holes under the elastic force of the springs 15, thereby fixing the lens 5 at the bottom of the lamp box 1. The limiting blocks 12 penetrate the fixed bars 13 and are fixedly connected with the fixed bars 13, which plays a role of driving the compression of the springs 15, ensuring that the fixed bars 13 can be stably clamped into the limiting holes. When disassembly is needed, the fixed bars 13 are pulled out of the limiting holes by pulling the pull plate 14, and the lens 5 can be disassembled.
[0026] With reference to Figure 1 and Figure 2 In this embodiment, the heat dissipation assembly includes a heat dissipation base plate 8, a plurality of chips 9 are fixedly connected to the bottom of the heat dissipation base plate 8 and are uniformly distributed, the heat dissipation base plate 8 is fixedly connected to the top inside of the lamp box 1, a plurality of heat dissipation fins 3 are fixedly connected to the top of the heat dissipation base plate 8 and are uniformly distributed, and the heat dissipation fins 3 penetrate the top of the lamp box 1.
[0027] Specifically, the heat dissipation base plate 8 is fixedly connected to the top inside of the lamp box 1, and the heat generated by the chips 9 during work is first conducted to the heat dissipation base plate 8. The heat dissipation base plate 8 is made of a material with good heat conduction performance, which can quickly spread the heat.

The limiting block 12 penetrates the fixed bar 13 and is fixedly connected with the fixed bar 13, which plays the role of driving the spring 15 to compress, ensuring that the fixed bar 13 can be stably clamped into the limiting hole. When disassembly is needed, pull the pull plate 14 to make the fixed bar 13 disengage from the limiting hole. The heat dissipation base plate 8 is fixedly connected to the inside top of the lamp box 1, and the heat generated by the chip 9 during work is first conducted to the heat dissipation base plate 8.
