Green Packers Kampman Jersey -

www.cri-report.com - LED, a kind of semiconductor Green Packers Kampman Jersey diode, can transfer electrical energy to optical energy, and emit yellow, green, blue and other visible light as well as infrared and ultraviolet invisible light. Compared with small incandescent bulbs and neon lamps, LED is characterized by low working voltage and current, high reliability, long service time, easy adjustment of brightness, etc.

The entry threshold has been lowered gradually from upstream industry to downstream industry of the LED industry chain. The upstream industry is single chip and its epitaxy, the midstream industry is LED chip processing, and the downstream industry is package test and application, among which upstream and midstream industries are the fields with most fierce international competition, highest business risks, rich technology content and huge capital investment. In LED industry chain, the profit of LED epitaxial chips and chips accounts for about 70% of the industry, that of LED package accounts for about 10%-20%, and that of LED application also accounts for about Green Packers Kampman Jersey 10%-20%.

Under the circumstances of global energy crisis and increasing requirement of environmental protection, energy-saving, safe, micro and environmentally-friendly semiconductor LED lighting with long service time and rich colors has been universally recognized as the principal way for energy saving. Semiconductor lamps adopt LED as a new light source, whose consumption is only 1/10 electricity of that of general incandescent lamps Green Packers Kampman Jersey and service time prolongs 100 times under the same brightness. In 2010, the scale of global LED market exceeded USD 10 billion. It is predicted that the annual compound growth rate of global LED market will be over 20% in 2011-2015.

Global LED industry mainly concentrates in Japan, Taiwan, Europe and America, South Korea and Mainland China, among which Japan occupies 50% shares and is the world's largest producing country of the LED industry.

After 30-year development, the LED industry in China has initially formed a relatively complete industry chain, covering all the links of LED substrate, epitaxial chips, chip package and application. By the end of 2010, there have been over 1,000 LED relevant enterprises in China. These enterprises mainly concentrate in the downstream package and application fields, whose development of extension and chip links relatively lags behind.
