"Small lamp revolution" breaks foreign monopoly

outdoor electronic screens, car headlights, smart flashers... Are inseparable from light emitting diodes (LEDs), which are smaller than sesame seeds and are leading a "Lighting revolution". 3. The hammer return is abnormal. More than 70% of the global LED application products are processed and manufactured in China, but the core technology has been monopolized by foreign enterprises. Today, the silicon substrate LED light source produced by Jingneng optoelectronics Co., Ltd. has changed the situation that imported products occupy the high-end market

at present, there are three kinds of LED substrates - Sapphire, silicon carbide and silicon. Compared with sapphire substrates, which are widely used now, silicon substrates are not only cheap and easy to promote, but also improve the reliability of lamp systems. However, due to the extremely difficult technical research, many developed countries gave up this project early

since 2003, the team of Professor Jiang Fengyi of Nanchang University has focused on silicon substrate LED technology. After long-term efforts, silicon substrate LED technology has been successfully developed and industrialized through cooperation with crystal optoelectronics

"our annual R & D investment is between 80million yuan and 100million yuan, accounting for about 10%. If we lack sufficient R & D investment, the development of enterprises will lag behind." Said Wang Min, CEO of Jingneng optoelectronics. In the LED components with the radius of hair, crystal optoelectronics has more than 130 international and domestic patented technologies

the energy consumption of LED lamps is only 1/10 of that of incandescent lamps and 1/2 of that of fluorescent lamps. According to the current lighting power consumption scale in China, if incandescent lamps and fluorescent lamps are partially replaced by LEDs, 100 billion kwh of electricity can be saved every year

with the gradual formation of the domestic aluminum alloy cable market, China's independently developed silicon substrate LED technology, as the third technical route of the global LED industry, is the core competitiveness of the rapid development of crystal optoelectronics, and also a wonderful epitome of the development of China's LED lighting industry from made in China to created in China

the evaluation of the National 863 expert group on this technology is: "it has broken the current situation that a Japanese company monopolizes sapphire substrate and an American company monopolizes silicon carbide based semiconductor lighting technology, forming a tripartite situation of sapphire, silicon carbide and silicon based semiconductor lighting technology solutions."

Jiangxi firmly grasps the advantages of the successful R & D and industrialization of silicon substrate LED technology, vigorously supports the development of the whole industrial chain, promotes the transformation of technological advantages into industrial advantages, and realizes the transformation from the technical commanding height of its stock price to the market commanding height, so as to build Nanchang into a national led valley

in recent years, Jiangxi has successively issued a series of scientific and technological innovation policy documents, such as the opinions on deeply implementing the innovation driven development strategy and promoting the construction of innovative provinces, the opinions on the implementation of the innovation driven "5511" project in Jiangxi Province, and several provisions on encouraging scientific researchers to innovate and start businesses, to strengthen the policy guarantee of scientific and technological innovation from the top-level design

at the same time, Jiangxi has made every effort to promote the increase of R & D investment in the whole society, promote the implementation of the action plan for promoting the transfer and transformation of scientific and technological achievements in Jiangxi Province, increase investment in scientific research, and build a bridge for the integration of production and research. In 2016, the provincial research and experimental development expenditure increased to 20.73 billion yuan, "said Mattias zachart, general manager of LANXESS, 1.82 times that of 2012; The dominant position of enterprise innovation was further strengthened, with R & D investment reaching 18.135 billion yuan, an increase of 93% over 2012
