Suzhou produced nano small slide break through the bottleneck of China's LED industry

LED industry in China at present more than 70% concentrated in the middle and lower reaches of yesterday, the first Guozihao nano industrialization project, Suzhou City, the first batch of "I niina crystal photoelectric Co. Gan LED epitaxial wafer" products such as batch trial is successful, Suzhou is expected to pull the wafer "Chinese LED industry" shen".

Chinese Academy of Sciences, Suzhou Institute of nanotechnology and nano bionics is the national research institutions, the establishment of the Institute in 2006, a total of 8 incubation of nanotechnology projects. Founded in July of this year, a total investment of 689 million yuan, by the Suzhou new SeaUnion Polytron Technologies Inc Investment Holdings Suzhou nanojoin photonics Co. Ltd is the first to realize the industrialization of the incubator project.

It is understood that the LED industry chain, including substrate, epitaxy, chip, packaging four links, including the highest epitaxial technology. More than 70% of China's LED industry is concentrated in the lowest profit industries. High end epitaxial film is the biggest bottleneck in the development of China's LED industry, more than 80% of the power of high-end LED epitaxial wafer and chip dependence on imports.

Yesterday, the reporter saw in the new Suzhou nanojoin photonics Co. Ltd., a batch of trial of "Gan LED epitaxial wafer is a diameter of about 5 cm round white translucent" glass ", according to the introduction," Gan epitaxial films on GaN LED "is made by nanotechnology, the thickness of only a few microns, each" glass "can be cut into 20 thousand" chip "," chip "is the equivalent of a tungsten incandescent lamp in" ", after the package, these" chip "into" beads "and eventually made LED lamps.

It is understood that the "Gan LED epitaxial wafer using the" PSS "on the growth of high brightness LED" technology, the technology includes 14 patents, including 8 independent intellectual property patents is the general manager of Suzhou new nano crystal photoelectric Co., Ltd. doctoral tutor Wang Huaibing's research results, the other 6 are Suzhou Institute of nano authorization the use of patent. The use of LED lighting technology, the brightness of the domestic market than the best similar lamp bright 40%, because the technology to break the foreign monopoly of large companies in China in the field of semiconductor lighting, so Wang Huaibing was honored as "the Suzhou Industrial Park, science and technology leading talent".

"Next year in April, the new nano crystal will be formally put into operation, will have an annual output of 370 thousand epitaxial wafers, 6 billion chips, the ability of the 750 thousand fluorescent tubes. "Wang Huaibing said, is expected to 2015, the domestic LED market size of up to 500 billion yuan or more.
