How to take-all LED?

"Insurgents"

LED is the most contemporary imagination investment of energy-saving environmental protection - if the market completely replace the existing lighting LED, the potential size of up to 3,000 billion U.S. dollars.

However, the Chinese mainland from which the enterprise is hard to share. Currently Nichia Chemical, Osram, Cree, represented by Japan, U.S. and European companies as the first camp, which led LED lighting market. China Taiwan and South Korea in the second camp, followed by their technology, still in break in stage lighting, a major supplier of consumer electronics products backlight LED. Mainland enterprises due to the scale of dispersion, backward technology, involving only the landscape decoration, advertising signs, outdoor large screen displays and other low-end market-based. Jinsha River through the power of capital to change the rules of the game.

Wu Shen Jun, the eyes focused on the most profitable upstream. And the photovoltaic industry is similar to the LED industry in the early growth of monopoly by the upper reaches of most of the profits, accounting for less than 20% of the number of the upstream industry chain enterprises can get 70% of the profits. And this one, of the substrate material industry technology development route is the hub of all aspects of technology.

Mature substrates for suppliers from around the world are few, are large-scale commercial application of no more than two techniques - the Japanese company Nichia Cree sapphire substrate and the United States, the company's silicon carbide lining end. The two companies have monopolized almost all substrate materials market, and created a complex patent system, to the desire for outsiders to enter set up technical barriers. In addition, only from Russia, Ukraine and other countries involved in several enterprises sapphire substrate material. In China, although a small number of companies prepared to invest into the sapphire substrate area, but is still in its early stages.

Wu Shen Jun is the trump card words against Japan and the U.S., a company called optical crystal. The company uses silicon chips as a substrate, is taking a new technology route, while reducing material costs, you can bypass the Nichia and Cree cloth under the patent walls.

Lattice Power of the unique technology from the Nanchang University Professor Feng-Yi Jiang, Jiang semiconductor light of painstaking research for decades, and finally a breakthrough in 2004, to direct growth of GaN on silicon, given the practical level the Blu-ray.
