Why China's LED thermal industry suffered cold market

From large outdoor screen to mobile phone backlight from ordinary, high-power LED (light emitting diode) lights to the children love flash shoes...... LED is creeping into our lives. The attention of the world as a new generation of light source, LED with high brightness, low heat, long life and other advantages, known as the green lighting source in twenty-first Century most development potential, the corresponding industries have become a new industry "xiangbobo". However, the industry hot, cold market tremble". This is the biggest embarrassment domestic LED lighting industry is currently facing the city in the 2008 Olympic Games and the 2010 World Expo Asian Games, almost all of the LED, are used in CREE, PHILPS and other foreign brands, domestic brands and very little LED. "Without government subsidies, estimated that most people don't use LED lamp. Industry penetration. But what makes LED enterprise's embarrassment, when other types of energy-saving products to enjoy government subsidies (such as air conditioning, automobile industry, etc.) LED but because there is no national standard industry, even if the government wants to send subsidies are no standard to follow. Currently, LED lighting subsidies are paid by the cities themselves, so they are generally subsidized to their own area of LED enterprises. As an emerging industry chain, make cost down, the mature technology is the LED industry chain. The upper, middle and lower reaches of the LED industry chain are epitaxial materials and chip processing, product components and module packaging, display and lighting applications. LED epitaxial wafer and chip industry accounts for about 70 of the profits, LED packaging accounted for about 10~20, LED about 10~20. statistics show that the production of semiconductor lighting enterprises in China more than 3000, 70 of which focus on the industry downstream, domestic LED epitaxial material, chip to middle and low, more than 80 of the power type chip, LED imported devices. In recent years, the government has built some of the Isaac pepper LED lighting industry base, 10~20 share of the profits but the LED industry is still hot Chinese with 70 of the Chinese people for the LED cost. This means that the control of the core technology of LED foreign companies if not to pull LED low cost, simple LED downstream of the Chinese LED industry only to achieve low-cost and allow the market to heat up to sacrifice their own profits, but not the downstream products of technical support, if the price is cheaper, and how many people dare to use. According to the analysis, the current technology of high-power LED lighting compared with the existing efficient light source and no obvious energy-saving advantages, while the initial investment cost is much higher. Large current in improving the efficiency of light is also a lot of heat into the heat treatment, if the heat treatment is not good and will greatly reduce the life of the LED, with the radiator and increase the cost and volume, so that the advantages of LED light source disappear. So, everything is not up to the requirements of the lighting market LED technology provoke disaster. Because LED lighting market has just started, the lack of a unified interface and specification, compatibility between products are lacking, resulting in LED lighting failure maintenance difficulties, the formation of many obstacles in the popularity of LED on the road. In the interview, some companies said, LED products are not uniform standards to produce, the same specifications of the different manufacturers of LED product performance or some parameters are not the same. LED lighting as a new technology, its efficiency of light, heat, color, brightness, illumination and other indicators are still not stable, lack of corresponding regulations, the market is easy to fall into chaos, which hinder the healthy development of LED industry. Although insiders are optimistic about the future of LED lighting industry, think of the new light source will be a replacement for exercise, the final semiconductor lighting will replace the traditional incandescent lamp and fluorescent lamp. But at this stage, due to the blind development of China's LED lighting industry exposed the lack of core technology, lack of innovation, market competition disorder and other issues.
