LED lamp price bottleneck analysis

It is reported that the biggest issue that restricts the promotion of LED lighting is the price of LED lamps. Faced with prices that are several times higher than those of energy-saving lamps, consumers tend to follow suit. Although the prices of LED lamps are falling, they are still away from consumers. The range that can be accepted is far apart.

First, the application of LED heat dissipation products is difficult. The structural design accounts for about 20% of the lamps. China's labor pricing has always been very low, 20% of the cost is very reasonable, and the biggest problem is how to be more innovative and design more reasonable.

The heat dissipation cost must be maintained at 5%. The actual heat dissipation design is very simple. Take two directions: First, the shorter the path between the LED chip and the external heat sink, the better. The shorter the heat dissipation design, the better. Second, the heat dissipation resistance. That is, there must be enough heat dissipation to the path and at the same time, there must be enough “heat-dissipation paths.” This part of the cost is mainly in the structure, and the cost for cooling is not much.

Second, LED application power weak power LED lighting is the weakest link, a serious lag behind the development of LED lighting, quality needs to be improved. The design now accounts for about 20% of the cost of the luminaire, which is somewhat high. With technical development power is about 5-10% the most reasonable.

The high cost of LED, in fact, compared to other current light sources, as the LED industry invented the blue LED in the 1990s, which led to the realization of LED white light, the cost of its realization is not high.

Third, the company has no core technology Most of the core patents in the upper reaches of the LED industry are in the hands of foreigners. We do not have mastered the core technologies. Although our LED application product manufacturing capacity accounts for 50% of the world's total, the share accounts for 50%. The profit is really the lowest one.

LED chips use a larger-size wafer fabrication process as the process and quantity increase, and will continue to reduce costs. In recent years, 20% per year speed has been reduced, and in the LED chip price factor, the improvement of light efficiency is also included in the price reduction. At the same price, a better product was purchased. The cost of LED lighting is mainly in the LED chip. As long as the price of the chip is reduced, the lumen price of the LED can be reduced to the equivalent of the energy-saving lamp at the current stage, and indoor lighting will naturally bloom everywhere.
