LED Lighting is recognized as the most eco-friendly lighting, major industrial countries in the world have developed their own development strategies and lighting LED lighting project, the United States plans to achieve in 2010 more than 50 percent of the country to be used for road lighting LED Street Light . If you have been to Times Square, the United States, you will notice a huge piece NASDAQ full color, it is a masterpiece of LED technology. The early 1990s, the development of computer technology and integrated circuit technology makes LED video display technology can be achieved, TV images directly on the screen, especially the mid-1990s, InGaN blue and green high brightness LED successfully developed and put into production quickly make outdoor screen applications greatly expanded the area of 100-300 square meters. currently LED displays are widely used in Beijing, Shanghai, Guangzhou, Chengdu and other cities stadiums, squares, streets and even the venue, shopping mall. 2010, the global LED market will reach $ 50 billion, China is 60 billion yuan, 12.5 billion yuan from last year‘s and this year‘s estimated 25 billion yuan output value, we can see that China‘s LED business is in a steady growth in the process. But the LED industry and the world as compared to more developed areas, we are still in the stage of a more downstream in the industrial scale, productivity and technology, such as mainland China is now an annual output of about 30 billion dollars, less than Taiwan (2009 65 billion) in half, only the equivalent of Japan‘s Nichia Chemical of a business (in 2009 three billion dollars). In transport, we walk every day to see traffic lights, maybe you did not think, most of these lights are made by LED, the application accounted for 10% of the LED market. Select this material is not only because of the high brightness LED, and good light color purity, not easy to be absorbed by the air, it is very clear, easy to identify, and even a growing number of airports are also using this material do beacon light, flood light other special lights. 1995 began, the majority of car manufacturers have adopted such a shock-resistant, power, fast response light source to make the car brake lights, tail lights and turn signals, the instrument can also be used for lighting and interior lighting. Using LED not only important economically, but also can be used in many specific areas: "You can use a medicine made from medical LED Lights, Japan has been to promote the growth of crops with LED lights, can also be disinfected by UV LED and air purification Because of its safety and reliability, with LED made led high bay, no spark, will not cause a gas explosion, greatly improving the safety of underground work, in addition, because of its very low power, so workers no longer carrying the day large and heavy power supply, and this is very meaningful. " Due to increase brightness light-emitting diode drop and prices, coupled with long-life, energy-saving, drive and control relatively simple, with light control and other advantages have gradually evolved from a simple landscape lights to now led street light, the future will in the coming large-scale electrical equipment.
