Global energy shortage and environmental pollution is particularly prominent in the rapid economic development Chinese, energy saving and environmental protection is Chinese to achieve sustainable economic and social development of the urgent need to solve the problem. China's annual lighting energy consumption accounts for about 12%~15% of the total energy consumption, as a major source of energy consumption, we must look for a new generation of energy-saving light source as soon as possible to replace the traditional light source.
LED lighting with its traditional lighting sources do not have low power requirements, good driving performance, fast response speed, high seismic capacity, long service life, green environmental protection and continuous improvement of the luminous efficiency and other advantages, has become the world's most likely to replace the traditional light source a new generation of light source. Although semiconductor lighting business has just started with LED, there are many problems to solve, but with the rapid breakthrough lighting semiconductor technology and packaging technology continues to improve, LED in lighting applications began to form and gradually expand. At the present stage of restricting LED mass into the lighting field two bottleneck - low luminous efficiency and luminous flux of high cost, the application of LED mainly concentrated in the signal indication, intelligent display, automotive lighting, landscape lighting and special lighting etc..
In June 17, 2003 by the Ministry of science and technology group led the establishment of the national semiconductor lighting project coordination leading cross sectoral, cross regional, cross industry "". From the coordination leading group was established, by the end of 2005 this period of time is the semiconductor lighting project emergency start. From the beginning of 2006 in 11th Five-Year, the state will promote the semiconductor lighting project as a major project. After years of development, China's semiconductor LED industry chain has been relatively perfect, with a certain basis for the development of. At the same time, China is a big country in the lighting industry, as long as the government and industry to properly coordinate the appropriate integration, the development of semiconductor LED lighting industry is promising. LED semiconductor lighting market has great potential and broad prospects for development.
Since 2003, China's per capita GDP for the first time exceeded $1000 mark, the economic strength has been further enhanced, has received high cost flux (initial cost) source ability. In the next 5-10 years, with LED as the light source of semiconductor solid state, will gradually replace the traditional lights into every corner of the semiconductor LED solid-state light source to replace the traditional lighting source is represent the general trend.
Four problems, LED industry in china:
1, the lack of core patents. Patent, China congenitally deficient. Because the core technology in foreign countries, Chinese enterprises can only apply for a number of peripheral patents. There is no independent intellectual property rights, products in foreign markets can only find cross licensing. Shenzhen is now basically export export infringement, whether it is white, blue or white. "337 terms" is just the tip of the iceberg. Even in the country, in theory, LED is not illegal infringement sales. Although LED looks very prosperous, but there is no foundation of the core technology, which is China's LED industry sad.
2, the shortage of talents. LED is developing so fast that people can't keep up with it, including leading technology, engineering and technical workers. Now the quality of employees is very low, the average age and average cultural level is low. Is a high level of LED is a foreigner, China top high-tech banner, with "daluhuo" level of low tech LED. This seriously affected the quality of LED products.
3, the price is too high. China's LED industry is the advantage of the application, chip and package no advantage. LED application without specific hot spots everywhere, more than one thousand and six hundred kinds of commodities are hot. Ball bubble lamp, fluorescent lamp, spotlight and so on is only a form, LED backlight TV is only a transitional product. As the core technology of the chip and packaging are mostly controlled in the hands of foreign giants, chip prices become the lever to control the industry. At present, the international lighting giant out of their existing products, the protection of the excessive price has significantly hindered the development of LED. Take LED fluorescent lamp, a lamp, better than a few hundred LED, calculate the shell and drive, the price is difficult to come down. In many users do not consider the premise of environmental pollution, T5 lamp because of its high efficiency, easy to replace, cheap, mature system, more likely to allow consumers to accept.
4, vicious competition, market confusion. No core patents, most of China's LED enterprises can only focus on the middle and lower reaches of the LED industry chain, low barriers to entry, resulting in China's LED market environment chaos. Human resources, money first; technology research and development, is the doctrine. Inter enterprise mutual plagiarism, digging people, technology and products a large number of repeated, with independent technology companies are very helpless, there is no reasonable solution. Even more serious is that there is no uniform standard of China's LED industry, there is no certification system, there is no supervision system. So that the Chinese market LED products, strictly speaking, 90% failed.
Many enterprises for a period of time to do lighting, time and lighting products, more and more complex, exacerbated the market turmoil. With the development of the industry, a large number of enterprises swarmed into the market will be 3750 into a family of 37500, or even more, when the industry spontaneously formed out of competition, a large number of small and medium enterprises will be eliminated in the fierce competition. Ten years later, many of the LED companies will not exist, or bankruptcy or career change. Then foreign capital predators through capital, in the form of mergers and acquisitions into China
