LED street lamp for intelligent traffic

Abstract

The invention discloses an LED street lamp for intelligent traffic. The LED street lamp comprises a supporting rod and a lamp mounting rack. The lamp mounting rack comprises a workbench and a base. The workbench is fixedly connected with the base through a connecting rod. An ambient light sensor is arranged at the top of the workbench. A water collection hopper is arranged at the top of the base.A lampshade is arranged at the bottom of the base. LED lamp bulbs are arranged in the lampshade. A water collection tank is arranged at the position, located at the bottom of the base, of the left side of the lampshade. A base box is arranged between the water collection tank and the lampshade. A storage battery and a stepping motor are arranged in the base box. A swing rod is arranged on the basebox. A brush seat is further arranged on the base box. A brush frame is movably connected to the brush seat. A sweeping brush is arranged on the brush frame. The LED street lamp for intelligent traffic is completed, the LED street lamp can collect and drain rainwater, and the rainwater can be fully utilized; the cleaning function is automatically started for the lampshade of the LED street lamp;and the LED street lamp is low in power consumption and high in cleaning efficiency.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to an LED street lamp for intelligent transportation. Background technique [0002] LED street lamps are semiconductor lighting lamps. It is a high-efficiency solid-state light source that can emit light with weak electric energy based on the semiconductor PN junction. Under a certain forward bias voltage and injection current, the holes injected into the P region and the electrons injected into the N region diffuse to the The active area then emits photons through radiative recombination, which converts electrical energy directly into light energy. It is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, LED street lights will become the best choice for energy-saving renovation of road lighting. Road lighting is closely r...

AI Technical Summary

Problems solved by technology

LED street lamps are often dusty, dusty, and difficult to clean due to the traffic of cars on the road, which affects the lighting function, but the dust often accumulates on the outside of the lampshade.

[0003] According to the utility model of patent No. CN201621217008, a traffic intelligent LED street lamp has the advantage of being able to clean the outer wall of the lampshade and the inner wall of the dustproof cover by rainwater, but it cannot avoid the dust attached to the LED bulb. The impact force is very small and cannot be completely removed, and the device can only clean the outer wall of the lampshade and the inner wall of the dustproof cover when there is a large amount of rain in rainy days. The rainwater is not fully collected and discharged, and it is not fully utilized.
