In the current global energy shortage, LED as a new type of green light source product is the future development trend. With the further maturity of LED technology, it not only achieves better development in the field of room lighting design and development, in terms of transportation. It will also show its talents and will become a new growth point in this field.
LED enters the era of subway lighting
According to Shangpu Consulting Industry analysts, subway lighting has very high requirements. LED is undoubtedly the best choice. It has the unparalleled advantages of traditional lamps in terms of energy saving, stability and durability, and its strong shock resistance is very suitable for the subway. Operating environment.
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 250,000 lamps in the 302 subway 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 also 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 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 .
When the LED light effect reaches the use limit, the energy saving effect is no longer the final interest appeal point of LED lighting . In the future, the LED lighting competition is more reflected in the intelligent demand. National introduced the "underground places lighting led lights with technical specifications," details the subway led lighting equipment procurement specifications, and opened the way for the standardization of the subway led lighting.
In the "2013-2016 China led industry market prospects and investment value analysis report", Shangpu Consulting pointed out that LED is actually a semiconductor pn junction, which can directly convert electrical energy into light energy, and its life theoretical data can reach 100,000 hours. Metro Lighting led so many companies are jostling for subway lighting market, led to the people with the best lighting experience for everyone lit high quality of life, and left a city of lights into a new era.
