Metro lighting shows great LED energy-saving advantages

Following Beijing, Guangzhou, Wuhan, and Shenzhen, the Shanghai Metro is also equipped with LED lighting, becoming another major area where LED lighting is used in the subway.

Since the subway line is underground, lighting is required for operating hours, which also makes subway lighting a large part of the energy consumption. Compared with traditional lighting, LED lighting has great energy-saving advantages, so that LED lighting is a logical replacement for traditional lighting in the subway.

In addition, the subway will shake during operation, the life of ordinary lighting products will often be shortened, so that lighting products need to be replaced more frequently, and LED as a solid-state light source, its stability is better, and the life expectancy is much longer than the traditional lighting Products, so that staff can avoid the trouble of frequent maintenance and replacement of lamps.

At present, the number of domestic subways is about 48. At the same time, 28 cities are constructing subways, while existing domestic subway networks use traditional lighting. Among them, a total of 14 stations in public areas in Guangzhou, such as lighting systems, will start replacing energy-saving LED lamps this year, and the number of lamps will be about 18,000. Paris's public transport organization in Paris, RAPT, also cooperated with Philips and carried out LED reconstruction of 250,000 lights in 302 subway stations and 66 suburban subway stations of the Paris Rapid Railway network. The LED market potential of subway lighting can be described as enormous.

The “Technical Specification for LED Lighting for Metro Lighting” promulgated by China has detailed the purchase specifications for subway LED lighting fixtures, which has opened up a standardization path for subway LED lighting, and the application of LED lighting on subways will also be more extensive.
