LED with its advantages of high brightness, high efficiency, low heat, long life, is considered the most development potential in the 21st century lighting. In the market and policy driven by the rapid development of the domestic LED industry blowout has formed a relatively complete industrial chain, including the production of epitaxial wafers, chip preparation, packaging, integration, LED application. In 2010, China's LED industry scale, up from $ 827 billion in 2009 to 120 billion yuan, an annual growth rate of over 70%, higher than the 50% level of growth of the global LED lighting industry output value. Among them, the middle and lower reaches of the most complete industrial chain, accounting for 90% of the overall percentage of the GDP. China has become the world's leading LED manufacturing base and important application market. Expected in 2015, China will form a 600 billion yuan, the annual saving of more than 100 billion kwh of LED industrial scale.
To further promote the technological innovation of the LED industry, construction and wide application of independent industry chain, China Electronic Appliance Corporation and industry associations to organize the theme of "Focus on the core energy LED Exhibition will be held November 9-11, 2010 in Shanghai International Expo Center and the 78th China Electronics Fair over the same period will be held will create from raw materials, epitaxial wafers, chip, LED bracket, LED accessories, LED packaging and supporting materials, the LED backlight upstream firm to the upstream and downstream enterprises of the display, lighting, landscaping, decorative lighting, traffic lights, automotive lighting, special lighting, to the equipment, instrumentation, software, finance, consulting and other service enterprises and technological exchanges and market trading platform, help the domestic industry sustained and healthy development, and promote the steady expansion of the LED application market.
In the LED industry chain upstream of the epitaxial wafers and LED chips accounted for 70% of the profits of the whole industry, and technology-intensive, capital-intensive, where the core technology of the LED. Well-known epitaxial wafer and chip production enterprises will be exhibited a number of energy-efficient, low heat, cost-effective LED products, many of whom have excellent products of international advanced level. The CDH Technology Co., Ltd. was established in 1996, is a high-tech enterprise specialized in LED device packaging and lighting applications technical service commitment to the Ministry of Science and Technology Research and Development Program (863 Program) LED research and development topics and a number of Shanghai municipal LED R & D projects, is one of the LED is mainly pcb manufacturing enterprises in Shanghai. Set of global intelligence, exchange of professional equipment, focusing on production of high performance LED light-emitting diode, LED digital tube, LED matrix, high-power LED devices and modules, the COB form of LED light source, lighting, LED fluorescent lamps and lighting products and technology services.
