Semiconductor lighting (light-emitting diode, LED) is a new and efficient solid light source, with energy saving, environmental protection and long life and other significant advantages. The transformation of the world’s lighting industry and the rise of emerging semiconductor lighting industry, has become an indisputable fact. Advanced semiconductor lighting technology and products for its wide application and is considered the most promising in the 21st century high-tech areas. Present from the initial phone semiconductor lighting, traffic signals, display, landscape lighting, decorative and other special areas, began to enter the computer, television and other large-size LCD backlight has become the modern information society “to add luster to the “indispensable key components . Increasingly sophisticated car headlights, especially China’s urbanization, public infrastructure and other functions with the street lighting and commercial lighting, lighting for the semiconductor industry with a huge emerging market and development potential. In addition, agricultural, medical and many other emerging applications market has gradually developed. The next 5-10 years are likely to form the world nearly 1,000 billion dollars in semiconductor lighting application markets is expected to be another trillion dollar industry.
