Our country set up an inter-departmental coordination leading group, national semiconductor lighting project put forward a clear goal: by 2015 China’s LED industry scale will reach 500 billion yuan, the white LED light efficiency of 150-200 lumens per watt, which is expected to power saving 100 billion degrees, a year to save 350 billion tons of standard coal, carbon dioxide, sulfur dioxide and dust emissions of 100 million tons, 2 million jobs were created. Among them, the pearl river delta region in the national LED has a 42% market share, the 12th five-year plan of guangdong province also support key areas, including leds.
Technical disadvantage or restricting China’s LED industry development
LiuSongHao introduction, LED different criteria areas still exist, the situation of good and evil people mixed up. At present, guangdong has been start the standard optical components plan, with the help of military industry standard is introduced into the LED industry, through a national qualification testing station in the province to test the product on a regular basis, unified standards, the development of the industry will be gradually standardized.
LED lighting products(like 360 degree led bulb,ses light bulb, LED Globe light ) currently on the market there is a problem: use after a period of time the brightness to breakdown. This is an obstacle to large-scale application of LED. LiuSongHao thinks, MOCVD technology is a potential weakness LED industry development. MOCVD full name “meteorological metal organic chemical deposition”, is the key to the preparation of PN junction on the LED technology. Because of the related equipment manufacturing difficulty is very high, the LED domestic enterprises mainly rely on imports. Domestic MOCVD equipment began to put on the market in recent years, but mass production is still a certain distance.
