LED upstream industry rests in the hands of the vast majority of core patents foreign experts , we do not grasp the core technology , although we LED application products manufacturing capacity in the world accounted for 50 % share to 50% , but the profit is indeed one of the lowest ring .
LED chip with the process , the number of growth using larger wafer production process, will continue to reduce costs, lower rate of 20% annually in recent years , led chip prices factor in enhancing the efficiency of light you want to reduce the price also included in , the same price to buy a better product. The main cost of LED lighting in LED chip , as long as chip prices down , LED lumen unit can be reduced considerably with energy-saving lamps stage , indoor lighting naturally everywhere.
To get lower costs, the most important is to improve the technology dependent . According to the reporter , related technologies the United States, Japan and other more advanced LED lighting , our country is lagging behind , including cooling and LED manufacturing equipment industry is bound flawed . At present , Hunan enterprises are to strengthen research in this area. High-tech enterprises in the zone thousands of sub -emitting optoelectronic integrated development of the LED chip , it can effectively avoid overheating and affect the life of the bulb , LED lighting solve the problem not long power use. In the equipment manufacturing , CLP 48 then I want to break the domestic semiconductor lighting manufacturer outfits blank , capture key LED production equipment -MOCVD. If MOCVD smooth localization, will be able to reduce LED manufacturing costs , get rid of the foreign monopoly.
