Urban Rail Transit operating low-carbon policy
Rail transit vehicles use power running. Energy
consumption is less energy compared to buses. However,
due to railway stations usually built in underground,
lighting systems and air conditioning systems consume
power cannot be ignored. How to reduce the energy
consumption of rail transit operation is also very important.
First, the stations and operating vehicles internal select
LED lights. LED lights have light high efficiency (Im/W),
long life (30,000 �5 million) and other notable features.
While traditional light sources in the most energy-saving
fluorescent lamps are only 80lm/W light efficiency and
about 5000h life span. This new type of light source in
urban rail transit vehicles is gradually beginning to mass
use. As shown in Fig. 1
