Why the 21st Century Will Usher Industrial Revolution Again Since Edison Invented the Incandescent Lamp

Currently popular lighting fixtures on the market, either incandescent or fluorescent lamps, or gas discharge lamps, are vacuity or inflated state bulb products. The solid white light is a pure solid white light source, this light source make of the LED lighting material, also known as the white LED lighting devices. The appearance of bright LED especially GaN-based blue-green LED's rise makes application of LED occurred revolutionized, that is turned to light illumination. The invention of white LED on the end of the century makes humans lighting industry has entered a new period. Because of the huge market of human lighting revolution and the infinite significance to human survival and development. We entered a new era of solid-state lighting in twenty-first century.

Scientists predict that the twenty-first century will be the microelectronics and optoelectronics work together, play together era. Microelectronics and optoelectronics information technology depends on the rapid development of the two wheels. The solid-state lighting is the latest achievements of scientific and technological progress of the twenty-first century. The implement of the LED lighting will end up the era of last 120 years traditional incandescent lighting which is invented by Edison. This is not only the great revolution in lighting technology, but also the improvement of human life, is a great contribution for human progress.

As the LED lighting development potential, some advanced countries and regions make a national development plan on the development of LED. Japan began implementing the "21st Century Light Plan" from 1998 is expected white LED luminous efficiency of 120lm / w. Hoping to replace 50% of incandescent and fluorescent lamps in 2020. U.S. has also invested $ 500 millions, start the "next generation of lighting plan", target competed with the Japan for $ 40 billion LED lighting market. Europe and South Korea, intends to implement LED luminous efficiency of 200lm / w, far more than the current range of traditional lighting efficiency. Predicted that by 2015, the United States will have 75% of incandescent and fluorescent lamps are replaced by LED lights, saving $ 70 billion annually.
