Alliance concern LED street lighting

Road lighting production and people's life is closely related with our country city to speed up the process, LED lights green, efficient, long-life gradually into people's vision. At present, LED lighting technology matures, high-power LED light source efficiency has reached 80 lm/W, urban street lighting energy-saving transformation possible.

In order to street based high-power LED products market, there have been some LED companies in the second half of 2005, the successful development of LED street lamp products, and gradually to the market, replacing the original traditional street lamp products. Chinese is one of the world's fastest city process, can be expected in the next few decades, the country is huge for street lighting products LED high-power, high brightness, energy saving and the market demand. According to the 2006 National street lamp industry statistics, China's urban road lighting a total of more than 15 million streetlights, in recent years, the growth rate of more than 20%. According to this estimate, the annual national lighting street market size of not less than 5 billion yuan, such as the use of LED street lights, can save more than 2 billion degrees per year.

3311355 in recent years, the national semiconductor lighting engineering research and development and Industrial Alliance for LED city road lighting to do a lot of research work, understand the new achievements in the development of industry technology and market development trend. In 2005, the union recommended the solar LED street lamp to the Beijing Olympic Stadium owners units, more than 100 solar LED street lamps in the Olympic village scene show. The day before, the League participated in the Suzhou "2007 Chinese Road Lighting Forum, the forum to" technology "as the theme of the road lighting applications, nearly 200 more than the domestic road construction units and road lighting experts on behalf of participants, the application of LED light source in road lighting has become a hot topic of this meeting. In view of the current LED street lamp standards can not be quickly introduced the situation, the alliance is preparing to build a technical specification working group, ready to choose LED street lights as the starting point to study and develop appropriate test methods, technical specifications, etc..

Although China's LED road lighting has made considerable progress, but there are still some problems to be solved. The absence of such as LED road lighting products standard, high pressure sodium lamp illumination standard in different color index is not suitable for the LED light source; inferior product promotion have a negative impact on the market, shoddy products LED seriously disrupt the market, causing authorities on reliability of LED sceptical; the first high power LED lamp purchase cost is higher, about is 2-3 times of the traditional street lamp, which bring pressure to the market application of LED road lighting products.

LED road lighting ready market prospects and not perfect industry based on the status quo, union will hold the "2007 New Light & new energy solar semiconductor lighting" as the theme of the forum in Yangzhou in May 16th. The forum will further explore the development of solar semiconductor lighting, the application of key technologies and engineering exchanges. Focus on how to improve the performance of LED solar cells and reduce the cost, optimize the design of solar LED lighting system; how to regulate and develop the solar LED lights and other emerging products in the market of domestic application; how to guide the rational use of solar energy semiconductor lighting in municipal engineering, landscape lighting; how to seize the great opportunities of investment in emerging industries and international industry transfer the construction and policy and standards; industry environment. The General Assembly invited the relevant research and development, manufacture and design of solar energy and LED, related research and testing institutions, enterprises and urban planning and municipal engineering units, investment and financing institutions, bidding units and other participants. The forum has been given more attention and expectations because of its wide range of communication topics, diverse communication platforms and potential business opportunities.
