Isamu Akasaki Stockholm- Japanese and Hiroshi Amano, as well as American born in Japan Shuji Nakamura, rose yesterday with the Nobel Prize in Physics 2014 for having invented the light bulbs LED.
Isamu Akasaki, 85, was honored with two other young researchers, Hiroshi Amano, born in 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 efficient source of light 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 an area where they had all failed,” the jury that describes the discovery as “revolutionary.”
Stockholm- “This technology is ubiquitous in everyday life,” argued the jury that awarded the Nobel Prize in Physics 2014 Japanese Isamu Akasaki and Hiroshi Amano, as well as the US-born Japan Shuji Nakamura invented the LED light bulbs.
This light is on mobile phones, which plays an essential role in the illumination of the screens and TVs, Blu readers Ray and flashes of cameras, explained the jury.
When produced “blue luminous rays from semiconductors in the early nineties, led to a fundamental transformation in lighting technology,” the statement said of 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.
Furthermore, this finding led to improved energy efficiency. Before, for 200 thousand lumens, adequate lighting for a living room, 75 watts needed with conventional bulbs, but now the LED technology reduces power consumption up to 6 watts.
“also decreased material consumption since LED bulbs last up to 100,000 hours against thousand for incandescent bulbs, “said the statement from the jury.
” The LED bulb has a great potential to increase the quality of life of over a thousand 500 million people worldwide lack access to electricity networks: due to the low energy requirement can be powered by a cheap solar power, “said the jury
Council. Youth

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.
Other laureates, Isamu Akasaki, researchers advised: “Do not be fooled by fashionable issues. Do what you want, if it is really what you want to do. “
The three winners, who will receive the award on December 10 in Stockholm, a sum of about 883,000 euros will be distributed. The physics prize is the second of the 2014 Nobel season that began on Monday with the Medicine. Today Wednesday the Nobel Prize in chemistry is announced. (Hugues Honore / AFP)
