2014 Nobel Prize in physics: the blue LED illuminate the world
Three Nobel Laureate
Beijing on October 7, according to foreign media reports, 2014 Nobel Prize in Physics was awarded to three scientists from the United States and Japan, from, in recognition of their invention of the blue LED technology. Isamu Akasaki, Amano ho and Shuji Nakamura independence in the 1990s developed a blue LED technology, respectively.
The newly developed blue LED light source with the existing red and green LED light source, people can finally produce a more natural and practical white light source through three primary principles. The three winners will share the 8 million kronor ($ 1.2 million) in prize money.
At the press conference held on the 7th, the Nobel Committee announced the names of three scientists, they also therefore the Prize be awarded since 1901 a total of 196 highly respected scholars together to be remembered in that long list Single above. When the award-winning news was told, is Professor Shuji Nakamura of Japan was still asleep, he told reporters:. “This is simply incredible.”
In announcing the award, the Nobel Committee has also elaborated a huge significance winners of the invention has, and stressed that the purpose of the establishment of the Nobel Prize is to reward those scientists for the welfare of the entire human race to make a significant contribution. Professor Linkoping University in Sweden, a member of the Nobel Committee Orr · Andre Nas (Olle Inganas), said: “These applications allow Alfred Nobel Prize am very pleased.”
Chairman of the Nobel Committee, Professor Pierre Deer Xin (Per Delsing) Chalmers University of Technology, Sweden introduced the hard-won achievements of the winners, he said: “Interestingly, many large companies have tried previously to do this, but they all failed, but this is to adhere to a few people refused to give up their experiment again and again, and ultimately successful. “
Although the red and green LED technology has been around for many years, but the blue LED is much greater technical difficulty, it’s time for decades both the scientific community and industry feel troubled. Without them, we can not use the three primary principles of synthetic white lighting.
Now, using blue LED technology products into millions of households around the world, it gives you the lighting, it exists in your camera and phone. In offices and homes around the world, the white lights illuminate the room, but they consume energy is much smaller than incandescent lights and day. In presenting the award, the Nobel committee wrote: “The incandescent lamp to illuminate the 20th century, while the LED lights will illuminate the 21st century.”
Since a quarter of the world’s electricity is used for lighting purposes, more energy efficient lighting will have increasingly important in the global context of compressed carbon dioxide emissions. LED lights will also help the world more than 15 million people bid farewell to the era of no lighting, LED lights use less energy will allow local small solar power stations to achieve lighting possible.
University of Cambridge professor Sir Colin Han Furui (Sir Colin Humphreys) said: “This is a tremendous achievement, Isamu Akasaki, Amano ho and Shuji Nakamura deserved blue LED technology for the development of their invention bright and energy-saving lamps. more efficient lighting technology paved the way.
