Three key factors affecting the price of LED lighting products

Several key factors influencing the price of LED lighting products:

1, domestic enterprises without core technology

Most of the upstream LED industry's core patent master in foreign hands, we have no domestic core technology, although we LED applications in the global manufacturing capacity accounted for 50%, accounted for 50%, but profits in the lowest part does link. The cost of LED lighting is mainly in the LED chip, as long as the chip prices down, LED lumen unit price can be reduced to the equivalent of the current energy-saving lamps.

Because the LED chip technology, with the growth in the number of larger sizes for the wafer fabrication process, will continue to reduce costs, reduce the rate of 20% annually in recent years, LED chip price factor, will enhance the optical efficiency is also included in the lower price, the same price to buy better products, so the LED chip is also large the price of space.

2, LED application cooling

The cost of cooling must be maintained at 5%, the actual thermal design is very simple, following two directions: one is the LED chip and the external heat sink path shorter is better, the shorter the thermal design your better; two, the heat resistance is to have enough heat to heat the road path must also have enough "". This part of the cost is mainly in the structure, the structure of the lamp in the design of about 20%, for the cost of heat is not much. Now the biggest problem is how to achieve a more innovative, more reasonable structural design.

3, LED application power

Power supply is the weakest link of LED lighting, which restricts the development of LED lighting. Now the design accounts for about 20% of the cost of LED lighting, some high, with the development of power technology in the 5-10% is probably the most reasonable. LED light source and other light source compared to the afterlife, in fact, the cost is not high, especially in environmental protection, energy saving, LED does not contain mercury, and each quarter LED lighting prices are sliding down, in a relatively short period of time the price of LED lighting can reach acceptable levels.
