LED Tunnel Lighting Control Based on ZigBee

In order to solve the problem of tunnel lighting safety and energy waste, a tunnel lighting optimization system based on wireless communication is established. According to different light intensity changes and traffic flow outside the tunnel, and the related factors affecting the illumination in the tunnel, the system gives the dimming command through the algorithm to optimize the illuminance of the lamps and lanterns. The simulation results show that the system can optimize the illumination of lamps and lanterns, realize intelligent dimming controlled by single lamp in tunnels, and effectively save energy.
