STOCKHOLM, AFP.
Isamu Akasaki and Japanese Hiroshi Amano and the American born in Japan Shuji Nakamura , rose today October 7, 2014 with the Nobel Prize in Physics 2014 to have invented light bulbs LED.
Isamu Akasaki, 85, was honored with two other young researchers, Hiroshi Amano, born 1960 and Shuji Nakamura, born in 1954 in Japan and American nationality.
The Nobel jury said in a statement in Stockholm granting the award to three scientists for having “invented a new light source efficient from an energy point of view and beneficial for the environment. “
By inventing LED bulbs (light-emitting diode, light emitting diode), a new light source,” succeeded in area in which they had all failed, “the jury qualifies discovery” revolutionary. “
This technology is ubiquitous in everyday life, eg in mobile phones, which plays a role essential lighting displays and TVs, Blu-ray readers and flashes of cameras.
When produced “blue luminous rays from semiconductors in the early nineties, led to a fundamental transformation in lighting technology,” said the statement from the Royal Academy of Sciences in Sweden.
” For some time there were red and green LEDs, blue light but not white bulbs could create “the statement added.
In addition, this finding led to improved energy efficiency. Before, to get 1,200 lumens, adequate lighting for a living room, 75 watts is needed with conventional bulbs, but now the LED technology reduces power consumption up to 6 watts.
“also decreased material consumption because the LED bulbs last up to 100,000 hours versus 1,000 for incandescent bulbs, “said the statement from the jury.
” The LED bulb has a great potential to increase the quality of life of more than 1,500 million people worldwide who lack access to electricity networks: due to the low energy needs can be supplied by a cheap solar power, “the jury
.
- Tip to young researchers –
Profile Shuji Nakamura is atypical in the history of the Nobel Prize in Physics that falls almost exclusively on university researchers, as it carried out the research awards in a small company, Nichia Chemicals.
later emigrated to the United States to teach at the University of California, Santa Barbara, and became an American citizen.
“It’s incredible” Nakamura said when the Nobel Foundation called to announce the award.
“It’s very satisfying to see my dream of an LED lighting becomes reality,” then said the winner, who expressed his hope that ” LED bulbs help reduce energy use and descend the cost of electricity over the world. “
” I never thought of success or failure. I just did what I wanted to do. Fortunately, my colleagues will support me, “said meanwhile another laureates Isamu Akasaki in Japanese University Meijo in Nagoya, where he also investigates Hiroshi Amano.
Akasaki also used to give advice to young researchers “Do not be fooled by fashionable issues. Do what you want, if it is really what you want to do. “
The success of the three winners was based on the use of nitride gallium, discarded by other researchers and companies seeking the same goal.
The three winners, who will receive the award on December 10 in Stockholm , a sum of about 883,000 euros ($ 1.1 million) will be distributed .
In 2013, the winners were the Belgian François Englert and British Peter Higgs discovery of the Higgs boson, an elementary particle considered by scientists as the cornerstone of the fundamental structure of matter.
The physics prize is the second of the season 2014 Nobel began Monday with the medicine. On Wednesday the Nobel Prize in Chemistry, Literature on Thursday, will be announced on Friday Peace and Economics on Monday.
