Recently, the US market research company Communications Industry Researchers (CIR) speculated that China's LED industry market will reach 6.8 billion US dollars in 2008, an average annual growth of 20% to 30%. With the increase of LED application range, this information has an increasing trend. It is estimated that by 2010, the output value of the LED industry in the whole market will exceed 150 billion yuan. In the LED industry chain, LED chips and LED chips account for about 70% of the industry's profits, LED packaging is about 10% to 20%, and LED applications are about 10%~ 20%.
In the LED industry chain, because the chip and the epitaxial wafer (epitaxial wafer) have extremely high technical requirements, CIR believes that the current Chinese market is in urgent need of development in this respect, especially high-quality epitaxial wafers and chips. At present, there are more than 10 chips and epitaxial wafer companies that can be mass-produced in China, and about half of them can be produced. Due to the high technical requirements of epitaxial wafers, many chip manufacturers in China's market basically purchase epitaxial wafers from abroad and Taiwan and process them into chips. At present, the chip quality produced by chip manufacturers in China's market is generally much different than that of foreign countries, especially the two parameters of brightness and light efficiency. On the other hand, the output of chips in China's market and epitaxial wafers is very limited. Although the output has increased greatly in the past two years, it can only meet the demand of domestic packaging enterprises by 20% to 30%. With the rapid growth of LED applications, the demand for LED chips in LED packaging plants will become more urgent.
China's market LED packaging has been developed for several years, the gap between technology and foreign countries is not very large, the market's LED packaging products output has reached the world's first. At present, the development of LED is a large proportion of small power LEDs, but the profit has been greatly reduced compared with previous years, and the competition has intensified. The development momentum of high power in the past two years is strong, the development speed is quite fast, and the technical level is improved. obvious. In 2007, the number of LED packaging products in China's market reached 82 billion, with an annual growth rate of 30% to 40% and an output value of 16.8 billion yuan.
It is understood that in 2007, the output value of China's market application products has exceeded 30 billion yuan, and has become the world's largest producer and exporter of LED full-color display screens, solar LEDs, landscape lighting and other application products. The emerging semiconductor lighting industry is taking shape. China's market has formed certain characteristics in the field of lighting, among which outdoor lighting is the fastest growing. There are hundreds of LED street lighting companies and dozens of demonstration roads have been built, but the Chinese market is still showing in large-size LCD backlights and car headlights. behind. In China, the display screen of LED has been widely used. LED car lights are widely used, and the most demanding headlights may have new breakthroughs this year. LED backlights for LCDs have also reached the practical stage of application this year. LED street lights in 2008 may be heavily invested in road lighting, LED general lighting concept will be more clear.
