subject: LED chip patent case of bottlenecks in local enterprises have collapsed - china 12PSB Test Bench [print this page] Revenue from the domestic market, last year's domestic sales of LED chips is 65,000,000 yuan, which greatly exceeds the 10,000,000 yuan in 2003. LED Applications in 2008 revenue (RMB450 million), the account for the largest part of the package, and chip manufacturing, were 18.5 billion yuan and 19 billion yuan. Demand in the downstream applications under the stimulus is expected, many companies began to expand production, the three safety photoelectric MOCVD equipment this year, the expansion of 18 units to 33 units. In addition, some small chips in the field of technology is relatively mature companies, also began to prepare a project launched high-power chip. Domestic high-power LED chips is growing fast and light effects. In 2005, the use of imported chip package, China's best white LED light at 350mA current, efficiency reached 30? 35lm / W, while the use of domestic chip package but only 20-25lm / W. Now, the LED chip packaging has been made achieved under the 350mA current optical efficiency for the 80? 90lm / W.
