LED lighting break price barriers need to start from the technology

First, LED application cooling

Structural design in the light of about 20%, has been China's labor pricing will be very low, the cost of the 20% is very reasonable, the biggest problem is how to be more innovative, more reasonable design.

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 the path must also have enough heat the Road ". This part is mainly in the cost structure, cost is not much for cooling.

Two, LED application power weak

Power supply is the weakest link of LED lamps, seriously lagging behind the development of LED lamps, the quality needs to be improved. Now account for about 20% of the cost of lighting design, some high. With the development of power technology in 5-10% is probably the most reasonable.

LED high cost, in fact, is the current relative to other light sources, as was invented in 1990s Blu ray LED, which led to the realization of LED white light LED industry, in fact, the cost is not high. In particular, LED environmental protection, energy saving, mercury free, and the price of LED lamps in each quarter are slipping down, I believe that in a relatively short period of time to achieve acceptable levels of people.

Three, mainland enterprises without core technology

Most of the upstream LED industry's core patent master in foreign hands, we do not grasp the core technology, although we LED applications in the global manufacturing capacity accounted for 50%, accounted for 50%, but the profit is indeed the lowest ring.

LED chip technology, with the growth of a larger size 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. 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, indoor lighting naturally everywhere. LED chips are also large price space.

On the mainland, is expected in the next 3 to 5 years, with the development of the upstream chip, indoor lighting products occupy the proportion of semiconductor lighting products is very optimistic about the proportion of 40%.
