Self-cleaning LED street lamp

Abstract

The invention discloses a self-cleaning type LED street lamp. The street lamp comprises a lamp post and a lampshade fixedly connected to the upper end of the lamp post, the lower end of the lampshadeis opened and provided with a transparent cover, a lamp body is fixedly installed between the inner walls of the lampshade, sliding plug cylinders are fixedly connected to the opposite side walls of the lampshade, and magnetic sliding plugs are connected into the sliding plug cylinders in a sealed and sliding mode. According to the invention, a wiping mechanism, an axial fan, a evaporation liquid,an elastic air bag and a second permanent magnet block are arranged; the evaporation liquid can be promoted to absorb heat and evaporate in all seasons; the magnetic sliding plugs drive the first permanent magnet block to slide, the cleaning brush wipes the surface of the transparent cover to scrape dust so as to improve the lighting performance of the street lamp; meanwhile, the first permanentmagnet blocks can sequentially generate repulsive force with the different second permanent magnet blocks in the sliding process, so that the elastic air bag is extruded intermittently, the elastic air bag supplies water to the water outlet pipe, the water is sprayed to the surface of the transparent cover, and a better cleaning effect is achieved in cooperation with wiping of the cleaning brush.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a self-cleaning LED street lamp. Background technique [0002] LED lights have many advantages such as fast response efficiency, long service life, environmental protection, low power consumption, and high controllability. Therefore, they are widely used in the field of street lights. They are the most energy-saving and environmentally friendly lighting products used on various roads. [0003] However, because LEDs are in the outdoor environment for a long time, more specifically on both sides of the road, due to the constant traffic, there is a lot of dust in the environment, and LED street lights are usually composed of light poles, lampshades, transparent covers and LED lamp bodies. After a period of time, the dust floating in the air will adhere to the surface of the transparent cover at the lower end of the lampshade. As the dust continues to accumulate, the lighting performance of the L...

[0003] However, because LEDs are in the outdoor environment for a long time, more specifically on both sides of the road, due to the constant traffic, there is a lot of dust in the environment, and LED street lights are usually composed of light poles, lampshades, transparent covers and LED lamp bodies. After a period of time, the dust floating in the air will adhere to the surface of the transparent cover at the lower end of the lampshade. As the dust continues to accumulate, the lighting performance of the LED street light will become worse and worse, so it is necessary to wipe and clean the surface of the transparent cover to To improve its lighting performance, and because street lamps are usually relatively high, it is obviously unreasonable to use manual climbing and wiping to clean them, so it is necessary to design a self-cleaning device that can automatically wipe and clean the transparent cover of LED street lamps
