Self-cleaning device for LED street lamp

Abstract

The invention discloses a self-cleaning device for an LED street lamp. The self-cleaning device comprises a lamp pole and a lamp holder fixedly mounted at the top of the lamp pole through a connectingframe. A lamp body is fixedly mounted at the lower end of the lamp holder. The lower end of the side wall of the lamp holder is rotationally connected with a first gear ring, and the lower end of thefirst gear ring is fixedly connected with a lampshade. Through the arrangement of a wiping mechanism, a speed reduction band, a sealing plate, a sliding plug, a gear and the first gear ring, when anautomobile runs through the road beside the street lamp, the speed reduction band and the sealing plate can be pressed down, and therefore air is pumped into a device cavity; the sliding plug is pushed to move upwards, and therefore a threaded rod is driven to rotate, the gear is engaged with the first gear ring to rotate, the first gear ring drives the lampshade to rotate, dust on the lampshade is scraped away by an arc scraping strip, and cleanliness of the surface of the lampshade is kept; and when the sliding plug moves upwards, the air in the device cavity is extruded into a water collection cavity, and therefore water is extruded into the cavity, the arc scraping strip draw water, and therefore the cleaning effect is better when the lampshade is wiped.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a self-cleaning device for LED street lamps. Background technique [0002] Road lighting is closely related to people's production and life. With the acceleration of urbanization in our country, LED street lights have gradually entered people's field of vision because of their directional light emission, low power consumption, good driving characteristics, fast response, high shock resistance, and long service life. Long, green and environmental protection and other advantages, LED street lights will become the best choice for road lighting energy-saving renovation. [0003] However, because LED street lights have been in the road environment for a long time, the traffic on the road constantly raises dust on the road, so there is a lot of dust in the environment, and LED street lights are usually composed of light poles, lamp holders and lampshades. After a period of use, the air wi...

Problems solved by technology

[0003] However, because LED street lights have been in the road environment for a long time, the traffic on the road constantly raises dust on the road, so there is a lot of dust in the environment, and LED street lights are usually composed of light poles, lamp holders and lampshades. After a period of use, the air will 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 lamp will become worse and worse. It is necessary to wipe and clean the surface of the transparent cover to improve its lighting performance. Since street lamps are usually relatively high, it is obviously unreasonable to use manual climbing and wiping to clean them. Therefore, it is necessary to design a self-cleaning device that can automatically wipe and clean the transparent cover of LED street lamps.
