LED epitaxy chip in the first half of the standard is expected to launch - (AddTime - 2012-12-26)

"From the national level speaking, are working on semiconductor lighting standards, tube core change, control circuit of change, radiator plug replacement will work out a set of standard, the enterprise can do all kinds of model, but interface must agree general. Life problems which block the bad change which block." Beijing university physics professor, Beijing university wide bandgap semiconductor joint research center director ZhangGuoYi accept our newspaper reporter to interview: "200W led Flood light epitaxy chip standard review has passed, in the first half of this year may be introduced." Not only 200W led Flood light epitaxy chip standard in 2012 is expected to come on stage, along with the national policy to promote the development of 200W led Flood light lighting applications, is expected to 2015 China 200W led Flood light lighting market scale nearly $yuan. China is the world's second echelon 200W led Flood light in

In November 2011 the Chinese government announced incandescent lamp out after the schedule, subsidies amount about "one million only". 2011 200W led Flood light subsidies amount is not much, but it is good prospects for the development of this field, energy-saving lamps enterprise flocked 200W led Flood light lighting industry, leading to the 200W led Flood light lighting industry confusion. As ZhangGuoYi said, "is the current domestic flowers who do 200W led Flood light , engaged in packaging process of the enterprise can't statistics, may have notice." "Especially encapsulation technology can reduce the cost, there will be good and evil people mixed up, users in the use of, the first year of lighting will be very bright, and then a few years, if packaging is bad, will be the bottom of the chip drawing make light dark." Has electricity co., LTD., the energy industry department technical director GuYang accepting our newspaper reporter to interview said: "at present, the 200W led Flood light manufacturers in three areas, one is the bottom of the upstream chip production. The other is a middle chip packaging production, packaging into all kinds of size, various wattage. The third field is to be lower, namely lamp shell. Domestic reality is in the middle and lower reaches of the enterprise to do." For the present situation of 200W led Flood light industry, ZhangGuoYi said: "the bottom 200W led Flood light chip core technology can be divided into two echelon, the first echelon is Japan, the United States and Germany, their level is better than our leading 3-5 years, the second tier is China, Taiwan and South Korea." Domestic industrialization technology, research and development level and the foreign compared with only 3-5 years of gap, the question now is always have 3-5 years of gap, more than in China, from semiconductor power into power, if not beyond the past, just power cannot be power. " 200W led Flood light the future development direction is focus areas

ZhangGuoYi think, 200W led Flood light after ten years there are several changes: one is the equipment will be "zero step technology" trend. At present the main equipment is the United States, Germany's two enterprise monopoly. However, the national project support 200W led Flood light enterprises have eighteen. The future will be a fool 200W led Flood light technology. The second is now each manufacturer didn't do that division of labor, epitaxial spread only do epitaxial extension, chip only do chip. However, 200W led Flood light the development of the future will be in accordance with the division of the industry to focus on a certain area, industry division of labor do well will be conducive to the improvement of the overall technology. Three from product renewal terms, efficiency improve a little, life short, be helpful for the development of the industry. Because users don't want to once and for all, the hope can change style. The interview, many insiders are very concerned about the future 200W led Flood light overcapacity problem. From 200W led Flood light the market view, the first half of 2011 have declined in the second half of the trend, especially in the third quarter of the apparent overcapacity. "A surplus of reason is application market did not keep up with the speed of industrialization, some enterprise effects of holiday, dismount over." ZhangGuoYi said: "the next step 200W led Flood light industry will appear merger integration trend. If semiconductor lighting can't into thousands of households, the current capacity, if entered the piece, capacity is not enough."
