According to the requirements of "Guidelines for the Application of LED Lighting Technology in Shanghai Tunnels", Dalian Road East and West Line Tunnels have completed lighting renovations this year, all using LED lighting.
After the renovation of the Dalian Road Tunnel, the 35-watt LED lamp (color temperature is 5000K) replaces the original 75-watt fluorescent lamp, and the lamp life can reach 50,000 hours. This lighting retrofit uses wireless control to achieve separate control of each lamp in the tunnel, while achieving preset scene dimming, group dimming, and pre-fabricated brightness, traffic flow, sunshine time, fire alarm priority control, etc. The interface truly realizes intelligent dimming and fine dimming.
The online inspection function of the system performs real-time inspection on each lamp to accurately locate the lamps that have failed and control failure, and also improves the maintenance efficiency of the lamps.
As a vehicle tunnel, the lower color temperature, higher installation height and light distribution technology using diffuse reflection make the blue light generated by the LED tunnel light not harmful to the human eye.
