Smart Dimming Cabinet
LD-TG/II
The system collects data from the light sensor outside the tunnel, combines it with the lighting needs of different seasons, weather conditions, and time, and performs automatic time control on the tunnel lighting in groups. At the same time, the system can also collect information on vehicle flow through vehicle detection equipment, and perform intelligent dimming when there are few vehicles, so that the light is bright when the vehicle arrives and dimmed when the vehicle passes, thus achieving energy saving to the greatest extent while ensuring safety. The system collects and transmits data from light sensors, vehicle detection equipment, and lighting fixture monitoring in real time, performs multi-source fusion analysis, and based on the calculation results, the dimming equipment dynamically adjusts the brightness and color temperature of the lamps (the lamps must support adjustable color temperature), thus realizing intelligent lighting in the tunnel. This system is a mature and stable system that meets the needs of safety, energy saving, and intelligent lighting.
