LED street lamp is not the biggest advantage of energy saving control function

Sept. 11, "seventh Chinese Road Lighting Forum" held in Chongqing International Conference and Exhibition center. At the meeting, LED road lighting products and trends are still the focus of attention.

After decades of development, LED has been from the original red and yellow light, to the development of high brightness white light effect now, laboratory records has more than 160lm/W, the level of industrialization has exceeded 100lm/W. High power white LED lighting products in the field of general lighting applications continue to be a new breakthrough, so that LED in the city street lighting applications become possible. Compared to the traditional street lamp, LED street lamp because of its energy saving, environmental protection and other advantages, but also in 2009 to become the Ten City million pilot project to promote the object. But as a new industry, life and light problem LED high-power lighting products has become the focus of debate in the industry.

To solve this problem, technical director of the Shenzhen City Light Environmental Management Center Wu Chunhai, brought the statistics of Shenzhen City 63 LED lights, 27 companies. From March 18, 2009 to March 5, 2011, the daily switch lamp case, the total number of 17 sets of lights, lamps accounted for 27% of the total participation in the evaluation, involving 11 companies, accounting for 40.7% of the enterprises involved in the evaluation. Director Wu Chunhai summary, evaluation of LED street life should go to the field test, the evaluation should be tested in the laboratory of LED road light; at the same time, compared to the overall stability of the traditional street LED Street gap, LED street not much good, good business more difficult to find, LED street is very bad, good is also very good.

Shanghai Lighting Association chapter HAICONG also affirmed the development trend of LED, pointed out that the current LED lighting products have a very high lumen, and after these years of practice, LED lighting products have been from immature to mature gradually, but LED lighting products are still not mature enough.

Analysis in LED road lighting product advantages, light source and lighting engineering, Fudan University Professor Lin for said, compared HPSL and LED, the biggest feature is not such, but has more advantages in the control functions. Street smart is the biggest advantage in the future, the biggest energy is easy to control. But from the trend to large-scale applications, to consider the cost, reliability and other issues, these problems solved, the future is broader.

With the development of LED industry, LED lighting industry will move towards specialization, presented by Dr. Liu Jianping senior director of OSRAM products market, LED lighting production should be modular, modular need standardization. Do not modular development, not universal development.

LED technology becomes more mature, intelligent, standardized degree is more and more high, the application is also more and more. LED street lamp is widely used because of its energy saving effect, but it is not used in practice because of poor lighting quality. Wu Chunhai, director of the call, lighting quality and energy efficiency is the two wings of the LED street lights, are indispensable, must be balanced between the two. LED street lamp only better lighting effect can get support, promote scale application.
