China LED package patent lack of original packaging materials - (AddTime - 013-01-16)

After the July this year, guangdong again open 200W led Flood light packaging MOCVD equipment patent analysis warning. A few days ago, by guangdong intellectual property office of the province held 200W led Flood light industrial packaging and MOCVD equipment field core patent analysis and early warning report held in zhongshan.

According to the south China normal university optoelectronic materials and technology research institute professor of FanGuangHan report, 200W led Flood light packaging field, China in the original patent applications, ahead of the other countries, followed by Japan, the United States, South Korea was third fourth. In abroad 200W led Flood light packaging aspects of the research and development strength is not only focused on the structure above, but also for packaging material also has strong research. China mainly concentrated in the 200W led Flood light packaging structure design, when to use a better material, easy to disciplined by others.

In addition, foreign in packaging technology and structure of the above application emphasis on quality, as soon as the high quality of the patent, they will through the PCT and so on channel to each country kin patent applications, and China is their main target market. From domestic most of today's thermoelectric separation structure common touch imitation philips lumen structure patent can see, China in the packaging structure application quantity is very big, but not to the world, from some Angle can see the for their own patent quality not confident.

Global top 10 philips, samsung, LG, panasonic, sharp division, and other well-known manufacturers, a total of 5263 pieces for the patent, this is the future is still in the field of packaging main competitors. In China the applicant, the top three is Taiwan advanced electronic industrial co., LTD., macro qi technology co., LTD. And a interpretation precision industry co., LTD., China accounted for top 10 application for 18%, 13% and 11%, indicating that Taiwan in packaging field has great strength, and the future, Taiwan 200W led Flood light packaging peer is still strong competitors. The mainland's top six patent applicants is heshan li good electronic industrial co., LTD., foshan kingdom star electric co., LTD., tsinghua university, university of electronic science and technology, guangzhou south section integrated electronic co., LTD., the rainbow group company.

The report also shows that, in the field of MOCVD, from the United States, Japan, South Korea and Germany, China Taiwan the five main original countries or regions for the trend, in addition to the United States, Japan started earlier, but the other three countries and regions are the mid 1990 s began to apply for. The five countries and regions, although there are individual started relatively early, but since 2000 patent filings in the overall situation, all the fast growth.

China started quite late, in the field of patent number is still not much, originality and quality is not too ideal, there is no advantage. Germany, the United States AIXTRON VEECO in MOCVD technology has the advantage, accounting for 90% of the world market share, its core patent covers the growth reaction chamber design, heating, stage design, all in China and worldwide, the patent layout is MOCVD equipment core technology point.
