Blue color LED emitting diodes introduction:
1. Structure:
The blue light-emitting diode is a gallium nitride diode. The light-emitting diode is a diode made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc., which can radiate when electrons and holes recombine It emits visible light, so it can be used to make light-emitting diodes. Used as indicator lights in circuits and instruments, or composed of text or digital displays. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light.
2. Blue LED Nobel Prize:
The 2014 Nobel Prize in Physics was awarded to three scientists from the United States and Japan in recognition of their invention of the blue LED technology. Akasaki, Hiroshi Amano and Shuji Nakamura independently developed blue LED technology in the 1990s.
Combining the newly developed blue LED light source with the existing red and green LED light sources, people can finally produce a more natural and practical white light source through the principle of three primary colors. The three winners will share a prize of 8 million Swedish kronor (approximately US$1.2 million).
3. Blue LED meaning:
Red and green light-emitting diodes have come out in the middle of the last century, but to use light-emitting diodes for lighting, blue light-emitting diodes must be invented, because the three primary colors of red, green and blue can produce white light sources that illuminate the world. The manufacturing technology of blue light-emitting diodes has plagued mankind for more than 30 years.
In the 1980s, Isaac Akasaki and Hiroshi Amano, who worked at Nagoya University in Japan, chose gallium nitride materials to challenge the blue light-emitting diode world problem. In 1986, the two made high-quality gallium nitride crystals for the first time; in 1989, they successfully developed blue LEDs for the first time.
Since 1988, Shuji Nakamura, who was working at Nichia Chemical Company, also began to develop blue light diodes. Like the two Japanese counterparts, he chose gallium nitride material, but the technical route is not the same. In the early 1990s, Shuji Nakamura also developed blue light-emitting diodes. Compared with the Nagoya University team, the technology he invented is simpler and cheaper.
At this point, the biggest technical obstacle to using LEDs for lighting has been removed, and LED lights, known as the "fourth generation of lighting in human history", are about to emerge.
According to the Nobel Prize Selection Committee, this "young" invention, which is only "20 years old", was awarded because this white light source created in a completely new way has "benefited all of us". "Their invention is revolutionary," the statement said. "Incandescent lamps lit the 20th century, and the 21st century will be lit by LED lights."
Compared with incandescent lamps and fluorescent lamps, LEDs have lower energy consumption, longer lifespan, and can realize intelligent control. They are energy-saving and environmentally friendly "green lighting". Therefore, after entering the market, it showed explosive growth. According to Yang Jiexiang, manager of the National Semiconductor Lighting Application System Engineering Technology Research Center, my country’s LED output value in 2010 was more than 70 billion yuan; By 2013, the annual output value soared to more than 500 billion yuan. The lighting of homes, offices, roads and other places, as well as the gorgeous landscape lighting, the "main force" in these markets is now LED. "When talking about LED a few years ago, we need to popularize the public with science. Now the home is decorated, people will consider buying this kind of lamps that are more energy efficient than traditional energy-saving lamps."
