LED Lighting Advantage of Powerful High Prices How to Solve

LED lighting

According to the State Council issued a comprehensive energy reduction program of work , Development and Reform Commission through financial subsidies to promote LED lighting products 150 million . According to an energy-saving lamps are too expensive has been unable to solve the problem . Indoor lighting involves thousands of families, after the popularity of indoor lighting LED lighting market really bigger than the outdoor lighting market , LED interior lighting especially for use in rendering the atmosphere , with ever other sources are unparalleled advantages, but it in terms of the domestic market , the price is still too high , most people still can not afford . According to LED analysis, resulting in LED expensive mainly in the following reasons:

1.The Domestic Enterprises without Core Technology

LED upstream industry lies in the vast majority of core patents 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 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 cut.

2. LED Application Products Cooling Difficult

Structural design in the luminaire about 20% , has been hard-working people of China are priced 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.

3. LED Applications 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 prices are sliding down , I believe we can achieve an acceptable level of people in a short period of time.

Domestically , the next 3-5 years , with the development of the upstream chip , semiconductor lighting indoor lighting products accounted for 40% of the proportion of applications are very optimistic.
