The Biggest Advantage of LED Streetlight Is Control Function Instead of Conservation

In March 11, the Seventh China Road Lighting Forum was held at International Convention and Exhibition Centre in Chongqing. LED streetlight application and trend was focused most attention.

After several decades of development, LED has entered into a stage of high brightness white light from previous red/yellow light. The lab notes of luminous efficiency have exceeded 160lm/w and the level of industrialization has reached 100lm/w. In addition, major breakthroughs were made in the effort in term with high-power white light LED application in the field of lighting, so that made it possible to apply LED in city road lighting. When compared to traditional street light, LED has advantages of conservation and environment friendly. However, as a kind of new industry, its lifespan and light decay is the subject of debate in the industry.

With regard to this issue, Wu Chunhai, who is the supervisor of Shenzhen Light Environment Management Centre, reported the statistics about 63 LED street lights produced by 27 firms. From March 18, 2009 to March 5, 2011, the total amount of decayed lights is 17 under the condition of daily witch on/ off routine, accounting for 27 per cent and involving 11 firms with 40.7 per cent of total firms. According to Wu, LED lifespan should be tested on spot while light decay should be tested in lab. Meantime, LED's overall stability is worse than traditional street light. Good LED is in excellent performance but bad one is in very bad condition, added by Wu.

On the analysis of advantages of LED road lighting products, the biggest function is controlling function rather than conservation as compared to high voltage sodium lamp. LED Street light intelligentized will be the biggest strength in addition to easy control. If we solved following issues like large-scale application, save cost and reliability, LED's future would much more bright. The related integrated circuit is LM217L.
