Lighting Industry Industrial Revolution
Why is it said that the 21st century will usher in another industrial revolution in the lighting industry since Edison invented the incandescent lamp?
At present, the popular lighting equipment on the market, whether it is an incandescent lamp, a fluorescent lamp, or a gas discharge lamp, is a glass-shell product in a vacuum or inflated state. The solid-state white light is a pure solid white light source, which is made of semiconductor materials, also known as semiconductor white light devices, or LED light-emitting devices. The emergence of high-brightness LEDs, especially the rise of GaN-based blue-green LEDs, has revolutionized the use of LEDs - from indicator lights to lighting. The invention of the white LED at the end of the last century, the lighting industry of human beings has entered a new period. Due to the huge market of the human lighting revolution and its infinite significance to human survival and development, it is no exaggeration to believe that the significance and far-reaching impact of the upcoming lighting revolution will never come from the second technological revolution that occurred in the last two centuries. (The age of the steam engine and the age of microelectronics). The 21st century has ushered in a new era of solid-state lighting.
Lighting Industry Industrial Revolution
Scientists predict that the 21st century will be an era in which microelectronics and optoelectronics work together and work together. Microelectronics and optoelectronics are the two wheels on which information technology depends on the rapid development, and both are indispensable. And solid-state lighting is a new achievement of scientific and technological progress in the 21st century. The early realization of semiconductor lighting will bring the traditional lighting era that has been used for more than 120 years since Edison invented the incandescent lamp to a successful end. This is not only a huge revolution in human lighting and lighting technology over the years, but also a revolutionary promotion for the improvement of human life, which is a huge contribution to the progress of human beings.
Due to the development potential of LEDs in lighting, some advanced countries and regions have formulated development plans for the development of LEDs. Japan has implemented the "21st Century Light Plan" since 1998. It is expected that the luminous efficiency of white LEDs will reach 120lm/w in 2010, and by 2020, it is hoped that 50% of incandescent lamps and all fluorescent lamps will be replaced. The United States has also invested a huge sum of 500 million US dollars to launch the "Next Generation Lighting Source Project", aiming to compete with Japan, Europe and South Korea in the future 40 billion US dollar lighting source market. It plans to use LEDs with a luminous efficiency of 200lm by 2020. /w, far exceeding the efficiency of various traditional lighting sources at present. It is predicted that by 2010, 55% of incandescent and fluorescent lamps in the United States will be replaced by semiconductor lamps, which can save 35 billion US dollars of electricity every year. In addition, South Korea, Western Europe, Taiwan and mainland China are all in full swing to start their own "semiconductor lighting plan." Just like the replacement of electron tubes by transistors, the wave of semiconductor lamps replacing traditional lighting sources is bound to be surging and overwhelming. In the face of the huge temptation of the semiconductor lighting market, the three major lighting industry giants in WORLD, General Electric, Philips, Osram and other large companies have cooperated with semiconductor companies to establish semiconductor lighting companies. A battle to seize the commanding heights of the emerging semiconductor lighting industry has already started globally. .
