With China’s highway construction advance from the eastern plains to the western mountains , the tunnel is widely used in construction , but the traditional tunnel lighting consumes huge energy, the use of new LED tunnel lighting to reduce energy consumption become the development trend of tunnel lighting . To this end, the Ministry of Transport to promote LED tunnel lighting system to achieve that the lights turn on and off as the car comes and leaves lights in Yunnan , Hebei, Guangxi and other highways, and having achieved significant energy savings.
Yunnan Bao Ma Daozai highway tunnel, a car is entering the tunnel , the vehicle detectors sensitively detect the car at 200 meters away from the tunnel entrance, the tunnel lighting PLC control system immediately open loop，the energy-saving LED tunnel light lamps lit up , the vehicle smoothly enter and exit the tunnel , after detecting the vehicle has left and finding no vehicles inside the tunnel，another tunnel turn off the lighting control system, avoiding unnecessary energy consumption. Experts said , LED tunnel lighting ahs achieved good energy saving effect , on the one hand due to the high luminous efficiency and low power consumption of the semiconductor light-emitting diode, the brightness of LED tunnel lighting is adjustable, wecan adjust light levels inside the tunnel to meet the lighting needs of drivers , which led the control technology of the tunnel lighting , the energy-saving effect is remarkable.
Yunnan Ma Daozai tunnel implemented the LED lighting technology , supply and distribution system active power filter technology and nighttime vehicle sensor lighting control systems, etc.. Project uses a total of 51.64 kilowatts 858 sets of LED tunnel lighting to replace the original 770 sets of 146.19 kilowatts of high-pressure sodium lighting, effectively reduce energy consumption ; Active filter device reduces equipment damage generated by the instability electricity of the power supply; enabling vehicle sensors lighting control systems at night both ensure the lighting requirements of the passage of the vehicles, but also reduce the void lighting without the vehicle passing, the integrated energy-saving rate is 66% compared with the original HPS program.
It is understood that the existing 1957 HPS have been replaced with LED tunnel lighting in Qiuwo Liang tunnel , Yin ditch tunnel, Hejiagou tower ditch tunnel No. 2 tower ditch Tunnel in Hebei Chengde expressway , since the project was put into operation The average monthly saving is about 45,000 degrees , the annual saving is 540,000 degrees .
Currently, LED tunnel lighting and the control technology based on real-time traffic has been applied in Anhui Lv’an to Wuhan Expressway , Beijing-Taipei Expressway and Shanghai-Chengdu Expressway and many tunnels, which can save 40% to 80% electricity.
