LED tunnel lighting energy saving into a new engine"

Along with our country highway construction from the eastern plains to the Western Mountain Tunnel in advance, is widely used in construction, but the traditional tunnel lighting mode of huge energy consumption, the use of new technologies, new products to reduce the energy consumption of tunnel lighting has become the trend of development. To this end, the Ministry of transport in Yunnan, Hebei, Guangxi, and so on a number of highways to promote LED lighting system, to achieve the car lights, car lights go out, achieved significant energy saving effect.

Yunnan Dabao highway road tunnel, a car is entering the tunnel, 200 meters away from the tunnel entrance, vehicle detector is sensitive to detect the vehicle PLC control system in the tunnel lighting immediately open loop tunnel LED (light emitting diode) energy-saving lamps lit up, into and out of the tunnel smoothly the vehicle, another tunnel to detect the vehicle to leave the tunnel, found no vehicle control system, closed lighting, avoid unnecessary energy consumption. Experts said, LED tunnel lighting achieved good energy saving effect, on the one hand, thanks to its semiconductor light-emitting diode with high light efficiency, low power consumption characteristics; on the other hand, the brightness of the LED lamp can be adjusted, can adjust the brightness of the lights in the tunnel, to meet the lighting needs of the driver, which led to the tunnel lighting control technology, energy saving significant effect.

Madaozi tunnel Yunnan implementation LED lighting technology, power supply system of active power filter technology and vehicle induction lighting control system of 3 energy-saving technological transformation. A total of 858 sets of 51.64 kW LED lighting to replace the original 770 sets of 146.19 kilowatts of HPS lighting projects, effectively reduce the power consumption; active power filter is decreased as the quality of power supply instability produced by the damage of the electric equipment; at night enable vehicle induction lighting control system, which ensure the lighting requirements of vehicular traffic, and to reduce the vehicle through ineffective lighting, compared with the original HPS scheme, comprehensive saving rate of 66%.

It is understood that the Hebei Chengde expressway will fall Qiuwoliang tunnel, Yin Jia Gou tunnel, hejiagou tunnel, tunnel, Tunnel No. two tower tower existing 1957 high-pressure sodium lamp light source to replace the LED energy-saving light source, since the project put into operation, the average monthly saving of about 45 thousand degrees, section 540 thousand.

At present, LED lighting and according to the real-time traffic control technology has been in Anhui Lu'an Wuhan expressway, Beijing Taipei Expressway and Shanghai Chengdu expressway, a tunnel for the application, the statistics show that the electricity savings of 40% to 80%.
