Description

Light control structure for tri-state LED lights

technical field

The invention relates to an LED lamp, in particular to a light control structure for a three-state LED lamp.

Background technique

At present, urban street lamps basically use time controllers to control the on and off of street lamps. Due to the change of seasons, the time between dark and dawn changes gradually. If the lights are not turned off, it will cause inconvenience for people to travel or waste power.

After 9:00 p.m. in small cities in my country, and after 12:00 midnight in large and medium-sized cities, the roads are almost empty. Even in the bustling cities like Beijing, Shanghai, and Guangzhou, there are fewer pedestrians and vehicles on the roads after 2:00 a.m. . When the traffic flow is low, the street lighting maintains the brightness of the original lighting, instead of adjusting the lighting brightness as needed, which wastes power in vain. The existing infrared sensing and Doppler sensing (radar sensing) have a short detection distance and are not suitable for controlling street lamps.
