LEDs have been energy-efficient at the beginning of development, and as the stability of solid-state lighting, LED lighting has become a new choice for metro lighting after its development.
At present, there are about 48 domestic subways, and 28 cities are building subways, and traditional lighting is used in existing domestic subway networks. Among them, the lighting system of public areas in 14 stations in Guangzhou will start the replacement of energy-saving LED lamps this year, and the number of lamps and lanterns will be about 18,000. France's Paris public transport organization, Ratp, also cooperated with Philips to retrofit LEDs for the 250,000 lamps of the 302 metro stations of the Paris Express Railway network and 66 suburban subway stations. The LED market potential of the subway lighting is quite large.
Since China's subway LED lighting is still a tentative project under the leadership of the state, the commercialization idea is still unclear. The emc energy contract management model has played an important role in large-scale LED engineering projects such as subway lighting in foreign countries, but it is difficult to promote in China. In addition to the domestic understanding of it, there are still many institutional obstacles. It has caused great troubles to the commercialization cooperation process of domestic LED projects.
China's "Technical Specifications for LED Lighting for Metro Places" has detailed the procurement specifications for subway LED lighting, opening up a standardization path for subway LED lighting, and the application of LED lighting in the subway will be more extensive.
