MTR added LED lights to help reduce emissions of young tons of carbon monoxide 1800 tons
According to the Hong Kong Ta Kung Pao reported that the people of Hong Kong in the future take the MTR can enjoy closer to the natural and comfortable light, following the beginning of last year for the three train installation of light-emitting diode (LED) lighting system device, the MTR Announced that it will further expand the LED green lighting energy plan to the territory of the 136 trains of the MTR train, and one hundred twenty-nine advertising light boxes.At the beginning of last year, MTR spent $ 4 million on Hong Kong Island, Tsuen Wan and Tseung Kwan O three subway trains. The MTR concluded that the test received good results. In addition to saving energy, LED The lamp life is four times more durable than the traditional light pipe, up to 50,000 hours, and the replacement only need to change the chip can not release mercury and manufacturing light pipe waste. At the same time LED light closer to the natural daylight, and will not release the UV light, can protect the passenger eyes, during the test is widely welcomed by passengers.
In view of this, the MTRC has decided to further expand the 136-liter train to the Urban and Airport Express, including the Kwun Tong Line, the Tung Chung Line and the Airport Express. The construction works are expected to be completed in 2017, when the annual emissions of carbon monoxide will be reduced by 1,800 tons per year.In addition to the train using LED lighting system, the MTR will also start from the first quarter of this year, rainbow and Hung Hom station for 129 advertising light boxes for LED testing, the project is expected to be completed by the end of this year, the MTR is expected to use light boxes LED light can narrow the thickness of the light box to eighty millimeters, compared with the traditional one hundred and fifty mm light tube light box more space-saving, and advertising light box, if the individual LED damage, can be replaced by particles, without the entire disposal, reduce waste The production.However, the MTR also said that because the cost of LED system is higher than ordinary light pipe, so the MTR train energy saving program mainly in power and environmental protection play an advantage in the long term and its cost and traditional light pipe lighting system is similar.
