The Japanese Isamu Akasaki and Hiroshi Amano and American born in Japan Shuji Nakamura, were awarded the Nobel Prize in Physics 2014 for inventing the LED bulbs, saving energy.
Isamu Akasaki of 85, was honored with two researchers younger, Hiroshi Amano, born in 1960, and Shuji Nakamura, born in 1954 in Japan and American nationality.
The three scientists were honored for having “invented a effective new source of light from an energy point of view and beneficial for the environment, “the Nobel jury in Stockholm.
By inventing LED bulbs (light-emitting diode, light emitting diode) , a new light source, “they succeeded in an area where they had all failed,” the jury qualifies the finding of “revolutionary.”
This technology is ubiquitous in everyday life, mobile phones, which plays an essential role in the illumination of the screens.
Also in TVs, Blu-ray readers and the flashes of the cameras and, more cameras in the office and housing.
When produced “blue luminous rays from semiconductors in the early nineties, led to a fundamental transformation in lighting technology,” said the statement from the Swedish Royal Academy of sciences.
“For some time there were red and green diodes but blue light could not be created white bulbs,” he added.
The energy efficiency of LED bulbs transformed the perception we have the power of the bulbs.
Before, to get 1,200 lumens, good lighting for a living room, with classic 75-watt bulbs were needed. Now with LED technology achieves a 6-watt bulb, which greatly reduces the consumption.
