China's LED industry chain need core technology to expanding
2011-8-4When LED lighting industry develop fast,there has been controversy over-investment, even industry insiders believe that the domestic LED market has not really started, the frenzy of development will advance the future of production and markets.
In the concept of energy saving and low-carbon economy driven,LED has become a hot industry,so it attracting many investors. Goldman Sachs study that the global LED market annual growth rate estimated at 18% from 2008 to 2010.
LED industry blowout,industry chain loss.
As a global attention of a new generation of environmental light source. LED with its high brightness, low heat, long life and other advantages,is called the 21 century most developing green lighting source. At present, semiconductor LED lighting has been included in long-term technology development plan in China.Now it has formed epitaxial wafers,chip preparation, package integration, LED application industry chain.
Driven by the favorable policy,the domestic LED industry develop rapidly.According to statistics,there are about 60 upstream enterprises,device packaging enterprises more than 1,000 and more than 2,000 downstream application enterprises in China's LED lighting industry.LED industrial output value are 827 billion yuan in 2009.
LED lighting has been the fastest growing application market instead of LED backlight.By 2015, LED lighting market in the domestic value of penetration will reach 1:4.
As of the end of 2009,China had more than 3,000 LED enterprises,however,only 140 enterprises' annual output over 100 million.No enterprise's annual sales over $ 1 billion.Although China have large number of LED enterprises, the scale is generally small.
At present, the development of optoelectronic enterprises are mainly concentrated in the application field.Foreign companies and Taiwan companies have monopolized most LED core technology, domestic enterprises can only be turned to low-tech application field.
Lack of core technology,despite market expectations is high.But in this stage,due to blind development,China's LED lighting industry has exposed many problems such as lack of core technology and innovative capacity,the market disorderly competition and other issues.One side is the rapid development of LED industry,the other side is lack of technology and equipment. This is the current state of Chinese LED industry development.
