LED lighting project without electricity. Because LED lights generally use low voltage direct current (constant current) power supply. If AC 220V electricity supply, the need for specialized low-voltage DC output transformer means (such as 12V, 24V, etc.) by the LED driver to drive the LED lights, as shown in FIG. So the best time to take into account the new buildings with LED lights, then treat it in the architectural design, including design, LED lighting agent, which is much more economical. The building was originally owned by fluorescent lighting system to be transformed into LED lighting, the costly transformation, the transformation of a long time (such as the transformation of a subway station or a waiting hall of the lighting system). New LED lighting power supply system requires more than traditional lighting power supply system is more complicated, the cost is much higher, if there is no support and economic support policies are hard to be successful. Currently, LED lighting, semiconductor lighting industry development in China for the better, epitaxial silicon particular the rapid business, packaging companies continue to maintain a rapid growth in lighting applications made great progress. 2007 China LED application products output value has more than 30 billion yuan, LED lighting prices, has become a full-color LED display, solar LED, landscape lighting and other applications, the world's largest producer and exporter, emerging semiconductor lighting industry is taking shape . Domestic lighting in the area has a certain characteristics, including the fastest-growing outdoor lighting, LED lights have been hundreds of companies and dozens of model building roads, but in indoor general lighting market remained behind. 2008 Beijing Olympic Games to showcase LED lighting LED so that people have a new understanding, a strong impetus to the development of China's semiconductor lighting industry. Current Chinese semiconductor industry industry big but not strong, LED lighting Guinness, the core competitiveness remains to be further enhanced. For domestic enterprises, expand scale and improve product quality and technical level is the primary task of improving future bargaining power to obtain patents when manufacturers or gradually through the development of breakthroughs in core patents.
