           Energy and Environment in the 21st century, mankind faces a major test, so the green energy the focus of world attention. To lighting, for example, its electricity consumption accounts for about 20% of the total, significantly reduce electricity for lighting is an important way to save energy. The characteristics of its energy efficient LED, lighting in the area received an unprecedented opportunity. 
        LED light-emitting diodes, also known as light emitting diodes (Light Emitting Diode, abbreviated as LED) is a kind of energy can be transformed into a semiconductor light emitting devices, are solid-state light sources. It is the use of solid semiconductor chip as the light-emitting materials, when coupled with a positive voltage across the semiconductor compound in the carrier occurs, release excess energy to produce visible light induced photon emission. With the traditional incandescent light bulbs and other vacuum compared to semiconductor LED light source with incomparable advantages. Semiconductor LED extremely long working life, is the traditional lighting of more than 10 times, effectively reducing the cost; its low power consumption, high luminous efficiency, saving energy is the future energy strategy the right candidate; LED light sources are small in size, weight, Light, strong adaptability, and application design provides great flexibility; the high-power LED light source is a solid white light bulbs, no glass in the vacuum package, and thus resistant to impact and collision; LED light source or a pollution-free mercury source. 


          Especially in recent years with the improvement of LED chip technology, lower prices and the associated drive circuits mature, LED light source in lighting applications possible. Increasing tensions in the current global energy situation, some developed countries and regions in the world have implemented a plan to promote the development of LED industry. United States, Japan and Taiwan and other countries on the LED lighting efficiency is predicted, the U.S. 55% of the incandescent lamp, LED fluorescent lamp is replaced, the annual electricity savings of 35 billion U.S. dollars, an annual reduction of 755 million tons of carbon dioxide emissions. 100% Japan incandescent LED, can reduce the 1 - 2 nuclear power plant generating capacity, annual savings of 1 billion liters of crude oil consumption. Taiwan, 25% and 100% incandescent replacement LED lamp is an annual saving of 11 billion kWh of electricity. 


        Attracted worldwide attention in 2008 Beijing Olympic Games and 2010 Shanghai World Expo are invariably to focus on the theme of green energy, this gives LED lighting industry in China has brought great historical opportunity. Well-known research company, according to Chi Ang Consulting (Sinotes) recently released the forecast, in the Olympic Games, World Expo strong, driven by China's LED lighting market to grow from 4.85 billion in 2007 to 2010, rapid growth to 98.1 billion yuan. In the global energy shortage and environmental protection requirements continue to improve the situation, with LED lighting technology, high brightness, long life, energy saving, environmental protection and other significant advantages, with the rapid development of LED technology, LED light source of the time as the more general and more recent, will become the history of mankind following the incandescent lighting, fluorescent lighting and the new revolution.
