How to start with LED lighting to overcome 'high price obstacles?

The government promotes LED lighting products through financial subsidies. 0. 5 billion. According to the response of the relevant departments: the price of energy-saving lamps is too expensive to solve. Indoor lighting involves thousands of households. After led lighting is truly popularized, the market for indoor lighting is larger than that for outdoor lighting. LED is used in indoor lighting, especially in atmosphere rendering, it has incomparable advantages over any other light source in the past, but in terms of the current domestic market, the price is still too high, and most people can't afford it. The specific analysis may be caused by the following factors: the cost of core technology is too high. Most of the core patents in the upstream of led industry are in the hands of foreigners. We have not mastered the core technology, although the manufacturing capacity of our LED application products accounts for 50 and the share accounts for 50, the profit is indeed a low link. With the increase of technology and quantity, LED chips will adopt a larger wafer manufacturing process, which will continuously reduce the cost. In recent years, the speed will decrease at 20 per year. In the price factor of led chips, the improvement of light efficiency should also be included in the price reduction, and better products are purchased at the same price. The cost of LED lighting lamps mainly lies in LED chips. As long as the price of chips is lowered, the lumen unit price of LED can be reduced to the same level as that of energy-saving lamps at this stage, and indoor lighting will naturally blossom everywhere. LED chips still have a lot of room for price cuts. Reasonable heat dissipation design cost structural design accounts for about of lamps and lanterns. The price of 20 yuan is considered reasonable by the industrious Chinese people. The big problem is how to be more innovative and more reasonable in design. The heat dissipation cost should be maintained at 5, and the actual heat dissipation design is very simple. There are two directions: first, the shorter the path between the LED chip and the external radiator, the better, and the shorter your heat dissipation design will be; Second, the heat dissipation resistance means that there must be enough heat dissipation paths and enough heat dissipation paths. This part of the cost is mainly in the structure, and the cost for heat dissipation is not much. The cost of power supply is seriously lagging behind. Power supply is a weak link in led lamps, which seriously lags behind the development of led lamps and the quality needs to be improved. Now the design accounts for about 20 of the cost of lamps and lanterns, which is somewhat high. With the development of technology, the power supply is about 5-10 is reasonable. The high cost of LED is actually compared with other light sources at present. As an LED industry that invented blue LED only in 1990s and LED to the realization of LED white light, the current cost is not high. In particular, LED is environment-friendly, energy-saving and mercury-free, and the price of LED lamps is declining every quarter. I believe it will reach a level acceptable to people in a short period of time.
