Chinese Academy of Sciences Institute of LED lighting research and the success of the LED light chip manufacturing key equipment MOCVD LED equipment manufacturers in China entered a new stage of history.
MOCVD metal organic chemical vapor deposition, is the key equipment of the production of LED light chip technology is extremely difficult, the world s major monopolized by two companies, including Germany Aixtron with the United States Veeco s (Veeco s mergers and Emcore company MOCVD business) two home.
MOCVD technology roadmap: Aixtron planetary reaction (PlanetaryReactor), the the Aixtron merger ThomasSwan the ClosedCoupledShowerhead (CCS), the reaction chamber, using Veeco TurboDisc reaction chamber, there must be a high temperature and pressure control capabilities, including the amount of a variety of gases control, and all this in a confined space, it is clear difficulty is much higher than automobile engines, so a lot of foreign R & D for many years ultimately failed.
Due to the presence of monopoly and technical barriers, the manufacturers use high-priced strategy, to profiteering, a set of equipment of millions of dollars, thus the final LED chip prices remain high, transmitted to the downstream so that the price of LED lights also difficult to reduce, and ultimately lead to the LED lights difficult to spread, the only high-end users can enjoy this environmentally friendly energy-saving lighting products.
Developed successful MOCVD LED Lighting Institute of the Chinese Academy of Sciences, its technical level has reached the standard of the sale of the MOCVD, perhaps to be slightly worse than the famous reserves of the new generation of MOCVD equipment, but apparently the actual business running, you can input the industrial production of LED lamps, will eventually lead to lower prices of LED lights, so that ordinary people lucky enough to use this high-tech environmentally friendly products.
