LED lighting becomes a new choice for subway lighting1

LED has the characteristics of energy saving at the beginning of its development. In addition to its stability as a solid-state lighting, LED lighting has become a new choice for subway lighting after its development is mature. At present, there are about 48 subways in China, and 28 cities are building subways. The existing domestic subway network uses traditional lighting. Among them, the public area lighting system of 14 stations in Guangzhou will start the replacement of energy-saving LED lamps this year. The number of modified lamps is about 1. Set 80 thousand. The Paris public transport organization ratp of France also cooperated with Philips to carry out LED transformation on 302 lamps in 250 thousand subway stations and 66 suburban subway stations of the Paris Rapid Railway network traffic system. the LED market potential of subway lighting is quite huge. As China's subway LED lighting is still a tentative project under the leadership of the state, the commercialization idea is still unclear. In foreign large-scale LED projects such as subway lighting, emc energy contract management mode plays an important role, but it is difficult to promote in China, except that it is not well understood in China, there are still many institutional obstacles, which have caused great troubles to the commercialization cooperation process of domestic LED projects. The 'technical specification for LED lamps for subway lighting' issued by China has detailed the procurement specifications for subway LED lighting, which has opened up a standardized road for subway LED lighting, LED lighting will be more widely used in subway.
