MTR added LED lights help young row of 1800 tons of carbon monoxide emissions

According to Hongkong Ta Kung Pao reported, take MTR Hongkong residents can enjoy the day after more natural and comfortable light, following the beginning of last year to three trains equipped with a light emitting diode (LED) lighting system, the MTR announced the day before, will further expand the LED green lighting energy conservation plan to all one hundred and thirty-six columns of the MTR train. And one hundred and twenty-nine advertisements.

MTR early last year at a cost of HK $four million, the LED environmental protection lamp test plan in Hong Kong, Tsuen Wan and Tseung Kwan O three times city subway train, the MTR concluded that the test received good results, in addition to effective energy saving, LED lamp life than traditional light tube durable high four times, up to fifty thousand hours, and replacement just go for the chip can not release mercury and light pipe manufacturing waste. At the same time, LED light is closer to natural daylight, and does not release ultraviolet light, can protect the eyes of passengers, passengers are welcome during the test.

In view of this, the MTR has decided to further expand the energy conservation plan for the one hundred and thirty-six trains, including the Kwun Tong line, Tung Chung Line and the airport express line. Jin Zepei, chief engineer of Mtr Corporation, said the project is now being tendered and the installation work is expected to be completed in two years, which is expected to reduce the amount of carbon monoxide emissions per ton by the year of to one thousand and eight hundred tons.

In addition to train using LED lighting system, the MTR will also by the first quarter of this year, LED test for the rainbow and Hung Hom Station one hundred and twenty-nine advertising light boxes, the project is expected to be completed by the end of this year, the MTR is expected to advertisements using a LED light can be light box thickness narrowed to eighty mm, compared with the traditional one hundred and fifty mm the light pipe light box to save more space, and advertisements within individual LED if damaged, can be replaced by grain, without the disposal of waste reduction.

But the MTR also said that because the LED system cost as compared with ordinary light pipe, so the MTR train LED plan of energy saving and environmental protection in the main energy saving advantages, the long term cost with the traditional light pipe lighting system to.
