Hongkong Metro trial of the new environmental protection lighting system can save 30% power consumption

Hongkong subway and the University of science and technology cooperation in environmental protection, try a new lighting system in the train compartments, expected power consumption can be reduced by 30%. According to reports, the new lighting system using semiconductor luminous, is currently used in light pipe ten times and durable, can reduce waste and replacement costs, coupled with the semiconductor light emitting, the heat output than the light tube is low, also can reduce the power consumption of air conditioner. From 11 onwards, one of the trains will be tried by the University of science and technology in the development of the lighting system for one year. Chen Zhenghao, Dean of the Faculty of science and technology, added that the new lighting system releases very little ultraviolet light, which is suitable for the lady who loves beauty.

Chen Zhenghao pointed out that LED generally has 10 years of life, compared with the traditional household light pipe durable 6 times. LED also saves 30% of electricity compared to ordinary household light pipes. As a result of LED cold light source, low heat, air conditioning can reduce the power consumption.

Liu Zhuomin, director of the metro company car, pointed out that because of the current ballast has been used in the design of environmental protection, it is estimated that the new lighting system than the current car to save 30% of electricity.

A total of 30 trains a light pipe, the pilot program will be replaced by the 30 sets of LED light pipe, each tube possession of 56 LED, each about $2500, more expensive than the old light pipe device 1.5. Trial period for the new lighting system for one year, the subway will be according to their stability to decide whether to extend to all subway cars, station lighting and advertisement lamp box.
