(2010-01-28)How to ensure the quality of street light
LED street light is one system composed of several parts, including the light source, power supply, cooling module, the mechanical structure etc. Each of them had an impact on the performance of the entire fixture, and one certain part out of work would have fatal injuries on the street lamp. And it can be easily found that nearly half of manufacturers produce the power supply by their own. Is it very easy to design the power supply for LED street lamp? Obviously not. Under the circumstances of DC input and high current, it is not easy to achieve constant current regulator.
The foreign suppliers of LED street lights has deeply studied thermal and structural issues and obtained a lot of patented technology, while for some domestic manufacturers, "plagiarism" was so rampant that it seems that people has a feeling that they saw similar structural design and heat dissipation before. There is seldom real innovation. At present the optical design of LED street lights considered be mature technologies, while most of the manufacturers faced challenges on the structure and heat dissipation design because poor design may raise latent danger.
The heat dissipation system of Kingsun street light absorb the latest research from TsingHua University integrated optoelectronics national key lab. Kingsun street light also utilize professional respiratory device GORE, which is able to balance effectively the interior and exterior pressure caused by cycle of warming and cooling of the lamp body to extend the lifespan. The electronic controlling system that Kingsun designed also can control the fixture’s temperature automatically and it ensure the safety of the fixture as well.
