In the LED lighting industry, the current situation of uneven hot and cold market is very

LED as a new generation of global attention light source, with its high brightness, low heat, long life and other advantages, is known as the most promising development of the 21st century green light source, the corresponding industry has also become a new industry's "Hong Xiang." However, "The industry is hot and the market is cold and shivering." This is the biggest challenge facing the domestic LED lighting industry.

In the 2008 Olympic Games and the 2010 World Expo and Asian Games, almost all of the LEDs used were foreign brands such as CREE and Philips, but rarely saw domestic LED brands.

"Without government subsidies, it is estimated that most people will not use LED lights." However, what makes LED companies even more embarrassing is that when other types of energy-saving products enjoy direct subsidies from the national government, the LED industry has not introduced national standards for the industry. Even if the government wants to issue subsidies, there is no standard to follow. At present, the energy-saving subsidies for LED lighting are paid by the cities themselves, so they are generally subsidized to LED companies in their own areas. As an emerging industrial chain, letting the cost drop and making the technology mature is a matter of the entire LED industry chain. The upper, middle and lower reaches of the LED industry chain are epitaxial materials and chip processing, product device and module packaging, display and lighting applications. LED epitaxial wafers and chips account for about 70% of the industry's profits, LED packaging accounts for about 10% to 20%, LED applications account for about 10% to 20%.

Statistics show that China's semiconductor lighting production enterprises more than 3,000, of which 70% concentrated in the downstream of the industry, domestic LED epitaxial materials, chip mainly in the middle and low, more than 80% of power-based LED chips, devices rely on imports. In recent years, the government's Isaac's pepper noodles has built a number of LED lighting industry bases, but China's LED industry is still at the cost of 70% of the people competing for LED's 10% to 20% profit share. This means that if a foreign company controlling the LED core technology is not eager to lower the cost of LED, the Chinese LED industry that gathers LED downstream can only make a low price at the expense of their own profits and allow the market to heat up, but there is no downstream technology support. Products, even if the price is cheaper, how many people dare to use it.

According to the analysis, the current technology for making high-power LED lighting fixtures does not have obvious energy-saving advantages compared to existing high-efficiency light sources, but the initial investment cost is much higher. High currents increase the efficiency of light while also turning into heat energy. If the heat treatment is not good, it will greatly reduce the life of the LED, and increase the cost and volume of the heat sink, so that the advantages of the LED light source disappear. Therefore, all the LED technology that cannot meet the requirements of the lighting market has caused trouble. As the LED lighting market has just started, the lack of a unified interface and specifications, the lack of compatibility between the products, led to maintenance difficulties after the failure of LED lighting, forming a lot of obstacles in the road of LED popularity. In the interview, some companies stated that LED products do not have a uniform standard for production, and the same specifications of LED products have different product performance or certain parameters.

Although most people in the industry are optimistic about the future of the LED lighting industry, they believe that the new light source will set off an alternative movement. Eventually, semiconductor lighting will completely replace traditional fluorescent and incandescent lamps. At this stage, however, due to blind development, China's LED lighting industry has exposed problems such as lack of core technologies, insufficient innovation capacity, and disorderly market competition. LED lighting as an emerging technology, its own luminous efficiency, heat, color temperature, brightness, brightness and other indicators are still unstable, the lack of appropriate regulatory norms, the market is easy to fall into a state of confusion, thus hindering the healthy development of the LED industry.
