 1, the domestic enterprises, the core technology

    Upstream of the LED industry, most of the core patent lies in the hands of foreigners, we do not grasp the core technology, although the manufacturing capacity of LED application products accounted for 50% of the global share to 50 percent, but profit is indeed one of the lowest .

    LED chip with the process, increase in the number of larger wafer production process, will continue to reduce costs, reduce the rate of 20% annually in recent years, the LED chip price factor, to luminous efficiency enhancement also included in the price reduction the same price to buy a better product. The cost of LED lighting the LED chip, chip prices come down, LED lumen Price dropped of at this stage of energy-saving lamps, interior lighting is natural everywhere. led replacement bulbs chip is still a great room for price cuts.

    2, LED application product cooling is difficult

    Would account for about 20 percent in the structural design of the lighting in industrious people will have been priced very low, 20% of the cost very reasonable, the biggest problem is how to be more innovative, the design is more reasonable.

    Cooling costs to be maintained at 5%, the actual thermal design is very simple and protect the two directions: First, the LED chip and the external heat sink paths as short as possible, the shorter the better your thermal design; Second, the thermal resistance is sufficient heat reached the path must also have the cooling-road. "This part of the cost structure is not much used in cooling costs.

    3, LED weak application of power

    The power LED lighting is the weakest link, is seriously lagging behind the development of LED lighting, the quality needs to be improved. Design accounted for about 20% of the cost of lamps, some as high. As the technology development of power in about 5-10% of the most reasonable.

    LED costs are high compared with other light, as in the 1990s before the invention of blue light LED, the LED industry, leading to the white LED can be achieved, in fact, now the cost is not high. LED environmental protection, energy saving, no mercury, and every quarter of the price of LED lamps are sliding down, I believe we can achieve the acceptable level within a short period of time.

    Domestically, it is expected that the next 3-5 years, indoor outdoor post lights products accounted for 40% of the semiconductor lighting applications are very optimistic, with the development of the upstream chip.
