The Nobel Prize in Physics was awarded to researchers today Isamu Akasaki and Hiroshi Amano (Japan) and Shuji Nakamura (United States), the invention of the electroluminescent diode (LED), today announced the jury in a statement.
.Consecrated were recognized by the invention of this technology, which enables significant energy savings
“His invention was revolutionary,” considered the jury, which stated that “the incandescent lamps illuminated the twentieth century; The XXI century will be lit by LED lamps. “
The three researchers produced bright beams of blue light from semiconductors in the early 1990s, triggering a fundamental transformation in lighting technology, according to the jury’s Nobel prize.
Before, red and green diodes already existed, but without the blue light, white lamps could not be created.
Create the blue LED was a challenge that dragged on for . three decades
“They succeeded where all others have failed,” the jury said, adding: “With the advent of LED lamps, we have alternatives now more durable and more efficient than older light sources” .
The LED bulbs emit a brilliant white light, have a long duration and use far less energy than incandescent lights created by Thomas Edison in the nineteenth century.
Why have electricity needs very low, the LED bulbs can be connected to solar energy cheap and local, an advantage to over 1.5 billion people worldwide have no access to the electricity grid.
winners will share the prize of eight million Swedish kronor (equivalent to 883 000 euros).
Last year, the Nobel Prize in Physics was awarded to British Peter Higgs and Belgian François Englert for his discovery of “particle of God “, the sub-atomic Higgs boson, responsible for providing mass all elementary particles.
As is tradition, the winners will receive their prize at a formal ceremony in Stockholm on December 10, anniversary date of the death of the founder of the prize, Alfred Nobel in 1896.
