[0026] In this technical solution, the LED light panel 15 is protected by the lamp housing 1, cover plate 3, and transparent protective plate 4, preventing damage caused by collision or moisture. The U-shaped baffle 5, first elastic retaining plate 7, and slot 8 limit the cover plate 3 from detaching from the lamp housing 1.

The operation is convenient and efficient, significantly improving the efficiency of maintenance and replacement work and providing great convenience.
[0027] Example 2:
[0028] Based on Embodiment 1, this utility model is as follows: Figure 2 and Figure 6As shown, a fixed housing 13 is fixedly connected to the middle of the lamp housing 1.
