LED interior lighting needs to overcome the hi

Government through financial subsidies to promote LED lighting products 150 million. According to the relevant departments of reaction that: the price of energy-saving lamps are too expensive, has been unable to solve the problem. Indoor lighting involves millions of households, LED lighting is truly universal indoor lighting market is bigger than the outdoor lighting market, LED indoor lighting atmosphere rendering, has an unparalleled advantage of any other light source in the past, but on the The current domestic market is concerned, the price is still too high, the majority of the people can not afford that. Specific analysis may be the result of the following factors:

The core technology costs too high

lLED most of the core of the industry's upstream patent lies in the hands of foreigners, and we do not have to master the core technology, although we led bulb application products manufacturing capacity in the world accounted for 50% share to 50%, but profit is indeed the lowest .

LED chip with the process, the number of growth to a larger size wafer production process, and will continue to reduce costs, reduce the rate of 20% per year in recent years, LED chip price factor, you want to enhance light efficiency is also included in the price reduction in the same price to buy a better product. The cost of LED lighting in the LED chip, chip price down, LED lumen unit price can be reduced to considerable stage of energy-saving lamps, interior lighting nature everywhere. LED chip is still a great price cut.

Heat rational design cost

Structural design would account for about 20% of the lamps have been industrious people in China are priced very low, 20% of the cost very reasonable, the biggest problem is how to be more innovative, design more reasonable.

Cooling costs to be maintained at 5%, the actual thermal design is very simple, keeping guard at two directions: First, the path of the LED chip led tube and the external heat sink pieces, the shorter the better, the shorter the better your thermal design; Second, heat resistance have enough thermal spread path must also have enough "cooling road part of the cost structure for cooling costs are not.

Power costs seriously lagging behind

The power supply is the weakest link led lamps, led lamps is seriously lagging behind development, quality needs to be improved. Now Design accounts for about 20% of the cost of lighting, a little high. With the technical development of power in about 5-10% of the most reasonable.

LED costs are high, in fact, relative to other light source, as the 1990s, before the invention of blue LED, mr16 led white LED realized industry leading, in fact, now the cost is not high. Especially LED environmental protection, energy saving, no mercury, and every quarter of the price of LED lamps are sliding down, I believe we can reach the level of the people to accept a short period of time.
