Audiences were amazed by the tall and magnificent, bright and colorful 3D effect arena at the scene of Spring Festival Gala in 2012 and 2013. Thereinto, the background display screen installed by LED lamp beads made a great contribution and all of the LED light sources were manufactured and supplied by a technology company from Chongqing. In the near future, thses “Made in Chongqing” LED lights will sparkle in the metro stations in Paris, France.
It is known that 20 thousand LED tubes were carried to France first batch to provide lighting facility for metro stations in Paris. It is introduced that last year French Bus Company planned to replace its over 300 metro stations in Paris and 66 railway stations in suburb with LED lights. Some LED Company from Chong Qing won the bidding among 50 companies in the bid from all over the world, offering more than 50 thousand LED tubes for Paris metro stations and railway stations.
All of the 50 thousand LED tubes arrived in Paris in two years. At the scheduled time, metro stations and railway stations in Paris will be light up by LED tubes “Made in Chongqing”.
The LED intelligent lighting system has already been popularized and applied in Chongqing main urban area, districts and counties, Liupanshui in Guizhou, Jiaohe in Jilin, Huangshan in Anhui, including the world’s largest city intelligent LED road lighting system in Beibei Section of Chongqing-Wuhan high speed and Maiji Mountain Tunnel, the second longest high speed in Asia, etc.
The intelligent LED street light whose energy-saving efficiency reaches up to 75% and 8 years life time is leading a revolutionary change in lighting field. According to the related officials from Chongqing Science and Technology Commission, the specifications commonly used are 250W and 400W. Set 400W street light as an example, the power of the light is 400W and the ballast needed for the light is 70W, making up to 470W. A light consumes 5.64 kwh from 7 o’clock in the evening to 7 o’clock in the morning of next day.
But after installing single lamp intelligent controller, a 160W LED light can achieve the same result of a traditional 400W light, without ballast. By doing so, the light only consumes 1.92kwh in 12 hours, saving 3.72kwh a light one night. Calculating the electricity price of Chongqing street lamp of 0.53 yuan for a kilowatt in an hour, it can save 1.97 yuan for a light one night.
This year, Chongqing plans to set up 18 thousand street light. If they are all LED lights, they will save over 24 million kwh per year.
