In the afternoon of the 21st, the LED sector broke out, and the three stocks of Ganzhao Optoelectronics , Lianchuang Optoelectronics , and Jufei Optoelectronics went up and down, and Snowlight once had a daily limit.
The GaN-based blue light-emitting diode of silicon substrate is the first prize of the invention. Premier Li Keqiang presided over the State Council executive meeting on December 16 to approve the 2015 National Science and Technology Awards review results. The 2016 National Science and Technology Awards Conference will be held in Beijing in January.
The LED lighting industry with energy saving and environmental protection is a strategic emerging industry that is developing at home and abroad. There are three LED lighting technology routes in the world, namely sapphire substrate, silicon carbide substrate and GaN-based LED lighting technology route on silicon substrate. Among them, the first two technical routes were developed mainly in Japan and the United States. The main contributors were awarded the highest technology awards in Japan and the United States respectively. The three main inventors of the sapphire substrate technology route also won the 2014 Nobel Prize. The Bell Physics Award, the third silicon substrate LED technology route was developed by China, which is the result of the invention.
In June, the results of the 2015 National Science and Technology Awards released by the Ministry of Science and Technology showed that the high-efficiency GaN-based blue LED project on the silicon substrate, which was under the responsibility of Nanchang University, won the first prize of the National Technology Invention Award. Experts believe that the GaN-based blue LED manufacturing technology on silicon substrate is cheaper than sapphire and silicon carbide substrates, and it is also beneficial to improve the output efficiency of LED chips and play a supporting role in the development of the industry.
As a national key support, fostering the development of strategic emerging industries - LED lighting is the application of a new generation of lighting revolutionary technology, with energy saving, environmental protection, high efficiency, etc., especially in today's traditional energy, environmental pollution and other factors, LED lighting The industry has undoubtedly become the focus of key projects of national and social concern. Domestic companies involved in chip manufacturing have led Union Optical, three safety optoelectronics, HC SemiTek, dry according to optical, fly Photoelectric, Hongli Opto-electronic, Mason Technologies, the country star power and so on.
