Three factors constraining falling prices of LED lamps

　　The biggest problem is reported that currently restrict the promotion of LED lighting is the price of LED lights , in the face several times with respect to energy-saving lamps , incandescent into several times the price , consumers are often the next best thing , although the price of LED lights declining , but still acceptable to consumers from far away .

　　One , LED application products’ Cooling is difficult

　　Structural design in the luminaire is about 20% , has been China's labor price has been very low, 20 percent said it was a reasonable cost , the biggest problem is how to be more innovative , more reasonable .

　　Cooling to maintain the 5% cost , effective cooling design is very simple , always has two directions: First , LED chip and the heat sink element outside the path as short as possible , the shorter the better thermal design you ; Second , heat resistance , is to have enough heat spread path must also have sufficient " cooling path ." this is the main part of the cost structure for cooling costs not much.

　　Second, LED application power weak

　　Power is the weakest link in LED lamps , LED lamps is seriously lagging behind the development , quality needs to be improved . Now account for about 20% of the lighting design costs , some high . With technology development of power is probably the most reasonable in 5-10 % .

　　LED high cost , in fact, relative to the current source for the other , as in the 1990s before the invention of the blue LED, white LED can be achieved resulting in the LED industry, in fact, now the cost is not high . Especially LED environmentally friendly, energy-saving , no mercury, LED lamps and quarterly the prices are sliding down , I believe we can reach acceptable standards of people in a short period of time.

　　Third, non- core technology businesses

　　LED upstream industry lies in the vast majority of core patents are in the hands of foreigners , we do not grasp the core technology , although we LED application products manufacturing capacity in the world accounted for 50 % share to 50%, but is the lowest part of the profits actually .

　　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. LED chip is still a great price decrease.
