LED lighting product prices affect several key factors:

1, the domestic enterprises without core technology

LED upstream industry lies in the vast majority of core patents in the hands of foreigners, have not mastered the core technology of our country, although we LED application products manufacturing capacity in the world accounted for 50 % share to 50%, it does at least 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 grew larger wafers using the production process, will continue to reduce costs, a lower rate of 20% annually in recent years, LED chip prices to factor in enhancing the efficiency of light you want to reduce the price also included, the same price to buy a better product, so the LED chip is still a great price cut.

2, LED application products Cooling difficult

Cooling to maintain the 5% cost, the 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, 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.

3, LED power supply applications

Power is led lighting weakest link, restricting the development of LED lighting. Design now account for about 20% LED lighting costs, some high, as the technology development of power is about 5-10 % of the most reasonable. best led headlights http://bestledheadlight.com/
