Nanchang Optics Valley is expected to reshape the global LED industry pattern!

Three points in the world, China has one. Nanchang University Jiang team successfully developed silicon substrate LED technology, make China become the world after Japan and the US third master blue LED independent intellectual property rights of the country. This high-tech and successful industrialization, won the 2015 national technology invention award.

Currently, Nanchang is the world's only silicon substrate LED chip production city. Based on this, the Jiangxi provincial government in 2015 to develop a plan to build a national LED Optics Valley, built with the international core competitiveness of the whole industry chain LED R & D, manufacturing and application base.

Silicon substrate LED can bypass the International Patent Alliance five LED manufacturers, so that the fate of the industry is completely in the hands of the Chinese people. Nanchang mayor Guo An said, Nanchang, Optics Valley, not only to the global LED industry value chain top, but also from the epitaxial chip, chip, packaging, application and other advantages of the whole industry chain LED.

The industry believes that, in the global division of labor in the industry, the wave of international mergers and acquisitions, Nanchang Optics Valley, such as to seize the strategic opportunity, is expected to reshape the global LED industry pattern.

The "double" model of success

Known as the fourth generation light source semiconductor light-emitting diodes (referred to as LED) is the reform of the era of green lighting.

Back in 1962, LED came out. As a lighting source, is a breakthrough in Japan in 1993, the sapphire substrate LED technology was awarded the Nobel prize in 2014. In 1995, the United States successfully developed silicon carbide substrate LED technology, won the 2003 U.S. presidential technology invention award.

At the beginning of this century, China's LED upstream industry is almost blank, the downstream application has just started, power chips all rely on imports, the u.s..

In order to seize the opportunities of emerging industries, from the beginning of fifteen, the Ministry of science and technology to support LED technology and industrial development, the establishment of a national semiconductor lighting project coordination leading group to improve the international competitiveness of China's LED technology.

In 1996, Nanchang University, a 40 square meters of the laboratory, Jiang held 600 thousand yuan loan to start tracking Chinese dream, LED technology in japan. Four years later, he successfully developed a sapphire substrate blue, green, purple LED, where blue LED into mass production.

The rewriting of history is completely dependent on imports of domestic LED chip, but Jiang quickly into a new concern. More and more domestic LED downstream enterprises. Can be deadly is that technical patents are in the hands of Japan and the United States, the industry can be choked at any time.

Jiang determined not to do foreign technology of the shadow, but looking for the "independent innovation path China core". In 2004, Jiang bold choice silicon substrate Gan technology route.

In 2004, after thousands of experiments, the silicon substrate LED breakthrough, breaking the monopoly China Japan, the formation of global LED technology in a situation of tripartite confrontation situation. At present, the photoelectric conversion efficiency is more than 60%, and there are more than 147 authorized patents, of which there are about 47 international patents.

Lying in the laboratory, China core no life, the real industrialization is the international competitiveness. 2006, crystal energy (Jiangxi) photoelectric Co., Ltd. came into being, began the industrialization of silicon substrate LED technology.

In 2009, latticepower in the world to achieve the silicon substrate of low power LED chip production; in 2012, and the silicon substrate of high power LED chip production, which marks the silicon substrate LED technology industry matures, the international semiconductor lighting alliance as its annual news events. China in the field of silicon substrate LED technology and industrialization thus occupied the two heights.

In Nanchang, now the silicon substrate LED technology as the core of the formation of 12 industrial clusters, covering epitaxial wafers, chips, packaging, application and other industrial chain, in 2015 the output value of more than 5 billion yuan.

Industrial development faces multiple challenges

Nanchang Optics Valley, the construction goal is to 2020 LED industry's main business income of more than one hundred billion yuan, accounting for the country's total of 15%, of which silicon substrate LED technology revenue reached $fifty billion.

Silicon substrate LED technology luminous efficiency and sapphire and silicon carbide substrate LED technology quite, but the silicon substrate has a price advantage, but also for the direction of high demand lights, tunnel lights, miner's lamp and other areas have obvious advantages. Jiang Fengyi said.

However, compared with the other two technical routes, silicon substrate LED technology started late, the industry faces multiple challenges.

- small industrial scale, low market share. Experts, the current global LED chip, about 85% of the sapphire LED technology; about 13% of silicon carbide LED technology; silicon substrate LED technology due to the late start, the practice of industrialization is short, accounting for only the market share of 1% to 2%. In addition, the existing domestic silicon substrate LED product brand international visibility is not high.

- the market environment is bad, the industry vicious competition phenomenon. According to the relevant industry sources, the domestic LED market competition disorder, the majority of companies blindly follow imitation, accustomed to fight price, fight scale, fight investment, is not conducive to the healthy development of innovative enterprises. In addition, some areas of the administrative barriers still exist, there is the risk of knowledge of industrial enterprises and products, local protectionism has been guaranteed for a while, but not long. "

- overseas mergers and acquisitions blocked, brand and sales channels to expand the integration of great difficulty.

We plan to crystal energy as the acquisition of the Lumileds industry to undertake the platform, which will greatly enhance the domestic LED industry technology and manufacturing capabilities, and may even reshape the global LED industry pattern. Jinsha River venture co-founder and managing director, said wu.

- international giants to catch up with the pace to accelerate, to maintain the leading edge of technology is difficult. "Silicon substrate LED technology in China
