MTR trial LED lighting system, to promote the use of the whole line

LED light pipe with high energy efficiency is becoming more and more popular, in addition to the popularity of the LED TV, Hongkong Mtr Corporation started this week, in a line of Tsuen Wan line using LED lighting system. The LED lighting system saves 30% energy compared with the traditional light pipe, life expectancy is also more than the general optical tube durability of three times. MTR said that the new lighting system will not only save energy, but also to achieve environmental protection purposes, depending on the passenger reaction, considering the promotion to full use.

It is understood that Mtr Corporation invested 4 million yuan, in the installation of the environmental protection of the installation of the 3 trains, using high brightness LED. 3 Hong Kong MTR trains will be installed by the 64 high brightness LED chip lighting devices, one of which will be put into service this week in Tsuen Wan line, the remaining two in June 2009 before the service. MTR will also be at the rainbow station to test the new lighting system in the station for daily lighting purposes, the project is expected to be completed by August. At present, more than 100 trains will be put into service, and the MTR will test the new lighting system for two years, depending on the passenger 's response and technical feasibility. Department of electronic and computer engineering, Hong Kong University Science & Technology professor Chen Zhenghao is responsible for the research of the new system, new and improved high brightness LED is expected to use only 70% of the traditional power tube, namely 30% energy saving life up to 50 thousand hours, 3 times more durable than the general light tube, in addition, when a high brightness LED chip failure instead, just replace the chip, reduce waste, to achieve environmental benefits.
