LED street lights refer to street lights made of LED light sources, which have unique advantages such as high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index, which are of great significance to urban lighting and energy saving. Because the LED light source is easy to adjust the brightness, by adjusting the brightness of the LED street lamp, the brightness can adapt to the brightness of the environment and save energy. Because the existing street lamps are illuminated downward by the gathering of lampshades, there will be obvious transition areas between the street lamps in the darker environment. The LED light source has a long service life and slow decay, but in actual use, the actual brightness decays quickly because the surface of the green light source is easy to absorb dust and debris.

Moreover, the outside of a section of the rotating shaft 7 above the sleeve shaft 13 is a smooth surface without threads. When the threaded disk 8 moves to the bottom of the thread and enters the smooth surface of the rotating shaft 7 without threads, the rotating shaft 7 continues to rotate. The threaded disk 8 remains in this position, and the transmission sleeve 18 below the threaded disk 8 moves down on the threaded disk 8 During the process, under the downward pressure of the threaded disk 8, the inner wall below is embedded in the sleeve shaft 13, and the transmission sleeve 18 and the sleeve shaft 13 are relatively fixedly connected together through friction, so that the rotational torque of the rotating shaft 7 can be transmitted to the sleeve shaft 13 , thereby driving the sleeve shaft 13, the lower fixed plate 11, the upper fixed plate 12 and the cleaning brush 10 to rotate, so that the cleaning brush 10 can clean up the dust and sundries attached to the lamp panel 6, that is to say, when the rotating shaft 7 rotates to the screw thread Disc 8 goes to the bottom and makes opening and closing sheet 5 close up and continue to rotate to make cleaning brush 10 clean lamp panel 6 .

In this embodiment, the outer wall of the rotating shaft 7 is provided with a vertical keyway, and a sliding key is fixed inside the transmission sleeve 18, and the transmission sleeve 18 is connected with the rotating shaft 7 through the sliding key and the keyway, so that the transmission sleeve 18 can slide outside the rotating shaft 7 and can transmit torque to each other.
