Development Trend of LED is called the fourth generation light source or green light, energy saving, environmental protection, long life, small size and other characteristics, can be widely applied in various directions, display, decoration, backlight, general lighting and urban landscape and other fields . In recent years, some of the world's economically developed countries around the development of LED technology in a fierce competition. Since 2000 the United States invested $ 500 million to implement the "National Semiconductor Lighting Plan", the EU also in July 2000 announced the launch of a similar "Rainbow Project." Science and Technology with the support of the "863" program, the June 2003 first proposed the development of semiconductor lighting plan. Over the years, LED lighting with its energy-saving, environmental protection advantages, has received the attention of state and governments at all levels, all regions have introduced policies and initiatives to accelerate the development of LED lamps; public consumers of this new type of environmentally friendly lighting products have been craving Long. However, due to investment in technology and marketing costs remain high, making so that thousands of consumers waiting LED lighting products have been beyond the reach of LED lighting technology, the delay uncover its mysterious veil nobility! Application development history semiconductor P · N junction made of the principle LED light source came in the early 1960s, first appeared in 1964, a red light-emitting diode, after a yellow LED. Until 1994, blue, green LED was developed. 1996 by the Japanese Nichia Corporation (Nichia) successfully developed a white LED. LED LED lighting for its inherent characteristics, such as energy saving, long life, shock-resistant, fast response, cold light source and other characteristics, widely used in lights, lights, display, landscape lighting LED lighting in areas such as price, in our daily life everywhere, appliances, telephones, dashboard lighting, automotive anti-fog lights, traffic lights and so on. But because of its luminance difference, expensive and other restrictions can not be used as general-purpose light source application. In recent years, as people continue to study in depth the semiconductor light-emitting materials, LED manufacturing technology advances and new materials (nitride crystal and phosphor) the development and application of ultra-high brightness LED variety of colors made a breakthrough Advances in LED lighting Guinness, the luminous efficiency by approximately 1,000 times, and the color aspect has been achieved in all colors of visible light, the most important is the emergence of ultra-high brightness white LED, the LED applications across High efficiency lighting market has become possible. It has been noted that the high-brightness LED will be one of humanity following the Edison invented the incandescent light bulb, the greatest invention.
