Chongqing will carry out LED large sapphire crystal research

Before most used in outdoor LED will expand to the indoor light field. 5, the reporter from the Municipal Science and Technology Commission held the "121" science and technology demonstration project information conference was informed that the city will integrate global resources, to carry out the research of science and technology in the 6 to 8 inches LED sapphire crystal size.

Crystal clear sapphire crystal, is the core material for the production of energy-saving lamps LED. It is understood that only a handful of countries in the United States, Japan mastered the key technology of sapphire production, but more than 6 inches sapphire substrate development is still blank. The production of sapphire crystal equipment is also mainly dependent on imports, resulting in high prices LED energy-saving lamps.

"The larger the size of the crystal material, cutting and polishing, the less waste. According to the Municipal Science and Technology Commission, responsible person, I will carry out the "semiconductor lighting industry science and technology demonstration project" pilot in Beibei, intends to capture growth technology and processing technology of large size sapphire substrate, and independent R & D growth furnace equipment, in order to reduce the production cost of LED, and promote the formation of LED industrial chain.

It is understood that the launch of the international LED alliance by China, its international top LED research institutions will provide intellectual support for the project. At the same time, the project will develop an intelligent lighting control system combined with the Internet of things, in order to be widely used in the fields of industry, agriculture, medicine, LED and other fields.
