South Korea's latest development technology: cyan LED luminous efficiency increased by 30%

Days ago, South Korean Ministry of science and Technology Education said, by the South Korean domestic research group will be the luminous efficiency of the second generation lighting source InGaN blue LED had the highest increase of more than 30% successful source technology development.

The development of the technology of compared with the former LED, not low electrical characteristics, depending on the optical waveguide phenomenon of zinc oxide nano rod, the luminous efficiency is increased more than 30%. Professor Zheng Jianyong of the Kwangju Institute of science and technology, said: "the research results from the material fee or fee will be relatively simple engineering side of zinc oxide optical waveguide effect (ZnO) rod at low temperature, will not affect the LED electrode structure and make growth, is the luminous efficiency of technology across the source of the increase, in the future the research of nanotechnology and fusion, will be $110 billion in 2015 and the interests of the world LED lighting market".
