The two-way road of the thin silicon substrate LED
The development of the silicon substrate LED industry is affecting the hearts of the two committee members. During the two sessions in 2015 and 2016, the committee members repeatedly voiced the silicon substrate LED, suggesting that the industrial development of the silicon substrate LED should be raised to the national strategy. Nowadays, the industrialization of LED substrate technology has been officially written into the “13th Five-Year Energy Conservation and Environmental Protection Industry Development Plan†jointly issued by the National Development and Reform Commission and the Ministry of Science and Technology. The development of the silicon substrate LED industry has ushered in new opportunities. Two conferences in 2015: The Jiangxi delegation proposed to promote the industrialization of silicon substrate LEDs into a national strategy and focus on promoting it in March 2015. At the third meeting of the 12th National People's Congress, the Jiangxi delegation made recommendations: 1. Promoting silicon lining The development of the bottom LED industry is listed as a national strategy, and the relevant special funds are fully supported and promoted. Second, the implementation of innovation-driven development strategy; Third, accelerate the promotion and application of silicon substrate LED technology products; Fourth, strengthen the silicon substrate LED technology core patent technology Protection and construction of national standards; 5. Encourage policy-oriented financial institutions to play a guiding role. 2016 two sessions: two representatives on behalf of Guo An, Zhu Liqiu recommended silicon substrate LED as a national strategy National People's Congress, Nanchang City, Jiangxi Province, mayor Guo An: It is recommended to raise the silicon substrate LED into a national strategy, support the industry to become bigger and stronger Guo An, the representative of the National People's Congress and the mayor of Nanchang City, Jiangxi Province, said that China's silicon substrate LED technology has broken the monopoly of European and American technology and stood at the top of the global LED industry value chain. It is recommended that the country raise the silicon substrate LED to a national strategy and support The silicon substrate LED technology upgrade and the industry become bigger and stronger. Guo An said that LED is the direction of future lighting development, but the core technology has long been monopolized by Japan and the United States. Last year, the silicon substrate LED technology developed by the team of Professor Jiang Fengyi of Nanchang University won the first prize of national technology invention and became sapphire and carbonization. After the silicon, the world's third LED technology route, which broke the monopoly of Japan and the United States for many years, let China stand at the top of the global LED industry value chain. Although breakthrough results have been achieved, at present, the first-mover advantage of China's silicon-based LED technology still faces three major challenges: First, the European and American countries have high awareness of economic and technological security, and it is difficult to expand and integrate overseas brands and channels in China's LED industry; The global international giants are catching up hard, and it is difficult for China to maintain the core technology first-mover advantage. Third, the domestic LED market is in disorderly competition. Most enterprises are imitating, accustomed to fighting prices, scaling, and investing. The local administrative barriers are not Completely eliminated. Guo An said that the LED industry has huge market potential. In 2014, China's LED industry reached 360.6 billion yuan, a 40% increase over 2013. It has maintained rapid growth for three consecutive years. In the future, the LED industry will maintain high growth. situation. But at present, China's LED high-end market, especially the high-power LED chips needed in the high-end lighting market, basically rely on imports. To this end, Guo An suggested that the state will raise the development of the silicon substrate LED industry to a national strategy. In the preparation of the 13th Five-Year Industrial Plan, the silicon substrate LED technology will be clearly regarded as the key development direction of the LED industry, and the silicon substrate LED technology upgrade will be supported. And the industry is bigger and stronger, with the silicon substrate LED technology to light the Chinese core, illuminate China, shine the world.
