With the LED lighting market blowout market, LED street development becomes clearer. Public companies have viewed for the LED street lamp market situation, LED as a new type of solid-state light source, has been in more and more areas of lighting show energy-saving effect. Such as the alternative to neon landscape lighting, energy savings of 70% to 80% energy saving LED traffic lights.
It seems the high cost is not the only factor to hinder LED companies settled with market, companies still need to overcome the technical performance of the challenging problems. Although the LED panel light industry developed fast in recent years, yet it still lacks the the authority technical standards, resulting in the industry as a whole varies greatly, and the promotion of a wide range of very adverse. This is the LED technology to evolute than reality faster desire.
Relatively high technical difficulty LED streetlight, the problem of lack of technical standards is particularly evident. According to statistics, all of Shanghai there are about 500,000 street lights, including the urban area of about 350,000, semiconductor lighting, currently only a short demonstration section Wuning Road. Many excellent technical LED manufacturers and integrators do not know how to design a practical street lights, the application departments can not tell the specific requirements. Shanghai Semiconductor Lighting Engineering Research Center for example, a lot of manufacturers, in order to solve the LED heat problem, design a “hollow” lampshade. But for the street light, the poor shape “shelter” function is not suitable for the street lights.
Also an obstacle to the development of streetlight is application promotion. Summarized as follows:
1, due to the informal standards of LED street lamp, it is not the general promotion of LED for street where several major parameters such as: color temperature, CRI (color rendering index) and glare has not been determined.
2, the price of LED street is too high. the streetlight building owners are bull system. This caused great difficulties to the LED street lamp promote the application.
3, the Ministry of Construction of the new street design standards develop “urban road lighting design standards” (CJJ45-2006), which started on July 1, 2007, but it did not mention the use of LED lights problem.
