There are 52 million road lights in U.S., of which 50% are highway lights, streetlights, LED tunnel light and the other half are the lights used in urban and public plaza such LED flood light, which is the world’s largest urban lighting system, more than China ( 35 million or so ) . U.S. Department of Energy planned to replace the existing arrangements with the LED street light in 2009, its start-up time is later than “Ten City, ten thousand lamps” advocated in China. The American LED road lights including the LED tunnel light are a part of road lights over the world , the plans and arrangements promoted is more rigorous .
As it is difficult to meet lighting requirements of the main road for the LED road lighting in terms of performance, the economic return is not satisfactory, so the United States LED road lighting is mainly focused on secondary roads and urban lighting on the road .
Since the 2010， the scale of several towns that is of different sizes were selected with the truck , the inland and coastal geographically ; different techno-economic conditions, using different products and programs to pilot the projects in order to obtain a more comprehensive test results under various conditions . Preliminary results obtained in begin , and the scope has been gradually expanded in other towns under a voluntary basis. According to incomplete statistics, the promotion and application accounting for less than 5% of total street . Now there are no city where all of the LED lights are used. Los Angeles firstly implementation of the world’s largest LED lighting scheme that 220,000 LED road lights including the LED street light and LED tunnel lights and other power LED lights plan to be installed, followed by the eastern Boston .
According to the above scheme，the municipal LED lighting Union was established on May 2010 to provide the various experimental cities and professional departments with a platform . Its purpose is to break the limitations of local , reduce repetitive test inputs, minimize investment risk and shorten the learning cycle of using the LED lighting. Summed up the exchange , providing a unified standard and software tools for project evaluation ,.
The LED road lights will be phased applied and tested in pilot cities . The first stage is to explore the improvement effectiveness of the application of lighting conditions and feasibility of investment returns . The second phase of the expansion of the trial period , the pursuit of technological improvements, the establishment of standards , cost-effective products and the level of application methods further improve ，achieve that the application of effects and economic benefits , environmental protection and energy conservation, social effects are enough to attract social investment . The third stage is the social capital investment of the natural introduction, so that the LED street light and LED tunnel light can be fully promoted. Some cities also divided the stage of the promotion and application into five phases . Preliminary estimates, which won’t be fully mature until 2020.
In addition to the USA，there are a large number of cities sparing no effort to promoting and applying the LED road lights，particularly the cities where there are vast number of popularity but limited resource，such as the Japan、China、India.
meanwhile，there are many professional company developing and producing LED road light over the world, lead lighting is one of them，Lead lighting has been continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light,LED street light， LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED flood light and LED tunnel light and other outdoor lighting，adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ，the soft and bright light of the LED tunnel light and LED street light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. click http://www.lead-lighting.com/products/bid32-1.htm for more detailed and professional features and uses of the LED tunnel light or return the homepage to know about more affordable and qualify LED light.
