Physics Nobel: the inventors of a very efficient lighting … – The Tribune.fr

“With the advent of LED bulbs, we now have more lasting and more efficient light sources to older alternatives.”

So the Royal Swedish Academy of Sciences has justified Tuesday, October 6 in a release are choosing to award the Nobel Prize in Physics in 2014 and the Japanese Isamu Akasaki Hiroshi Amano American and Japanese Shuji Nakamura. they have invented the LED (light emitting diode) source of sustainable and energy efficient lighting.

The red and green LEDs bulb already existed for fifty years, but it adds a blue light, it was previously not possible to create white light required for proper lighting.

“Effective from an energy point of view”

The invention provides three researchers “a new source of light and energy efficient a good perspective for the environment”, tells the jury described the invention of “revolutionary” and assured that “the twenty-first century will be illuminated by LED lights.”

While for 1200 lumens (good lighting in a living room), it was a conventional light bulb 75-watt LED bulb 6W can now suffice with this invention. “The material consumption is also reduced since LEDs last up to 100,000 hours, against 1,000 for incandescents” , said the jury.

A major revolution since “about a quarter of the electricity consumption worldwide is used for lighting” , said the Royal Swedish Academy of Sciences.

Isamu Akasaki (85 years ) conducted research with Hiroshi Amano (54) in Nagoya University, while Shuji Nakamura (60), born in Japan and now a researcher at the University of California at Santa Barbara (USA) , worked on the same subject in a small Japanese company.

Medicine, economics, chemistry, peace … the other Nobel Prize

Monday, October 6, the Nobel Prize in Medicine awarded an American-Columbia, John O’Keefe, and a Norwegian couple, Edvard and May-Britt Moser, for their research on the “internal GPS” of the brain. Other Nobel Prize-not least, suspense oblige- will be awarded later this week: Tuesday, October 7 for the Nobel Prize in Physics, Wednesday, Oct. 8 for the chemistry, Thursday, Oct. 9 for the literature prize on Friday 10 October for the Nobel Peace Prize, and Monday, October 13th for the economy.
