Advantage of rail LED lighting

At the end of 2014, the 22 cities in China, a total of opening operation of urban rail transit line length of 3173 km.Among them, 2365 kilometers of subway, accounting for 75%;Light rail 239 kilometers, accounting for 8%;Monorail 89 kilometers, accounting for 3%;Modern tram 141 kilometers, accounting for 4%;Maglev transportation 30 kilometers, accounting for 1%;Xiamen city fast rail 308 kilometers, accounting for 10%.

The rail transit lighting lamps and lanterns USES mostly type fluorescent lamp, metal halide lamp and high pressure sodium lamp and so on.There are many different kinds of lamps and lanterns, power is larger, neither convenient purchase and maintenance, and energy conservation, environmental protection, and the following problems:

（1） bare light source, glare harm;（2） the intensity of illumination on the low side, is there a difference between station and station, and lighting uniformity;（3） the lamps and lanterns light through a small proportion of effectively;（4） the lighting fixtures used mostly for the high efficiency and energy saving products, large energy consumption, high operation cost.

Rail transit is the hub of the city, lighting systems for rail vehicles accounted for subway system overall electricity consumption of about 13%, at present, the average energy consumption of metro lighting in 26 W/m2, far higher than the national standard （lighting standard 200 lx, energy consumption value control in under 6 W/m2）。Rail transit lighting problem increasingly prominent, energy consumption is becoming more and more high to the requirement of lighting energy saving.

Compared with traditional lighting lamps and lanterns, LED in rail transit applications with high energy saving, green environmental protection, strong shock resistance, strong stability and other advantages.Because of the rail transit to the stability factor of lighting lamps and lanterns and the demand is higher, vibration resistance and energy consumption.The LED is very suitable for rail transit field.

Rail transit lighting form a variety of LED lighting products, mainly reflects in: car interior lighting, car lights for external use only, station public area station layer, platform layer and the entrance hall lighting, etc.
