What are the reasons for the high price of LED lamps

　　LED lamps price is an important factor restricting the development of LED lighting , so, what make LED lamps such high prices ?

　　1, In LED application, led lighting power supply is the weakest point , which restricts the development of LED lighting . Design now account for about 20% LED lighting costs, some high , as the technology development of power in about 5-10 % of the most reasonable. LED light source contrast with other afterlife , in fact, the cost is not high, especially LED environmental protection, energy saving, no mercury , and every quarter of the price of LED lighting are sliding down , in a relatively short period of time LED lighting the price will be able to reach an acceptable level of people .

　　2 , The domestic enterprises without core technology LED upstream industry lies in the vast majority of core patents in the hands of foreigners , our country did not grasp the core technology , although we LED application products manufacturing capacity in the world accounted for 50 % share to 50% but really the lowest part of the profits of a ring . 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 . Because the LED chip with the process , the number of larger growth in the use of lighting project 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 have included lower prices , the same price to buy a better product , so the LED chip is still a great price cut.

　　3, LED cooling applications cooling costs is difficult to maintain at 5% , the actual thermal design is simple to grasp two directions : First , LED chip and external heatsink path as short as possible , the shorter your thermal design more good ; 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 , the structural design in the luminaire about 20% for cooling costs not much. The biggest problem now is how to do more creative , more reasonable structure design .
