Abstract

The invention discloses an LED street lamp with an automatic cleaning function. The LED street lamp comprises a lamp column, an LED lamp, a water storer and a water inlet valve; a nozzle is connected to the water storer through a pipe; and a water pump is arranged on the pipe. The LED street lamp further comprises a single-chip; photosensitive sensors are respectively mounted in the LED lamp and on the outer side of the LED lamp; the single-chip receives illumination intensity signals for comparison; when a difference value of two illumination intensity signals is higher than a set value, the water pump is triggered to work; a liquid level sensor is arranged in the water storer for acquiring liquid level signals in the water storer and transmitting to the single-chip; and when the liquid level is located in a set lowest level, the water inlet valve is controlled to feed water in the water storer. The LED street lamp can clean the surface under the condition of influencing normal use by floating soil on the surface thereof, can flexibly set the water spraying direction through a mode of multiple nozzles in one set, and finishes the purpose of automatic control through the single-chip control mode.

Description

technical field

[0001] The invention relates to the field of street lamps, in particular to an LED street lamp with automatic cleaning function. Background technique

[0002] Street lamps refer to lamps that provide lighting functions for roads. They generally refer to lamps within the road lighting range in traffic lighting. They are composed of lamps, electrical appliances, light sources, lamp poles, lamp arms, flanges, and foundation embedded parts. The stock of street lamps in China is between 28 million and 30 million. In recent years, the number of new street lamps added every year is 15%-20%, about 3-6 million. According to the number of newly added street lamps each year, all of them are LED lamps, calculated at 1000-2000 yuan each, the annual increase is 3 billion-6 billion yuan. The failure rate of LED street lights over 6000 hours is less than 1%. Lighting accounts for about 19% of the world's electricity consumption. If the efficiency of the lighting system ad...
