Stockholm – Isamu Akasaki and Japanese Hiroshi Amano and the Japanese-American Shuji Nakamura were honored today with Nobel Prize Physics for the invention of blue light emitting diodes, a discovery that triggered the development of LED technology used to illuminate computer screens and smartphones.

The Royal Swedish Academy of Sciences said the invention has just 20 years, “but it has helped to create white light in a completely new way for the benefit of all ‘.

For years scientists had worked to develop blue diodes, which are crucial to produce component white light from LEDs (light emitting diodes), until the three winners they succeeded in the early 1990s.

His work transformed the lighting technology, paving the way for LED lights, which are more durable and efficient than older light sources.

“They triumphed where all others had failed, ” said the Nobel committee. “ The tubes incandescent light illuminated the twentieth and twenty-first century will be illuminated by LED ‘bulbs’.

Akasaki, 85, teaches at Meijo University and is Distinguished Professor at the University Nagoya; Amano, 54, is a professor of Nagoya University; and Nakamura, 60, born in Japan, is a professor at the University of California at Santa Barbara.

Akasaki said in a press conference televised nationally often been told that their research does not give results within the twentieth century. “However, I never felt it was well ‘he said.” Was simply doing what he wanted to do.’ ‘

Akasaki and Amano produced their inventions while working at Nagoya University and Nakamura while working in Japanese company Nichia Chemicals. They built their own equipment and conducted thousands of experiments before achieving results.

In a statement from his university, Nakamura said he was honored to receive the award. “It’s very satisfying to see my dream on the LED lighting has come true, ” he said.” Hopefully the bulbs LED light, efficient in terms of energy, help reduce energy use and lower the cost of lighting in the world ‘.

The Nobel committee said the LED technology helps save land resources because a quarter of the world’s electricity consumption is used for lighting.

Loa LEDs are more efficient than older light sources and tend to last 10 times longer than fluorescent lamps and a hundred times longer than incandescent.

“The blue LED is a fundamental invention that is changing rapidly So we light every corner of the home, the street and the workplace: a practical invention that comes from a fundamental understanding of the physics of the solid ‘state,’ said H. Frederick Dylla, executive director and CEO of the American Institute of Physics.

Phillip Schewe, a physicist at the Joint Quantum Institute at the University of Maryland, said the award demonstrates that research in physics can produce practical benefits beyond investigating the mysteries of the universe.

Last year the Physics Prize was for the British Peter Higgs and Belgian Francois Englert to help explain how matter after the Primordial Burst formed.

Yesterday was awarded the Nobel Prize for medicine. Will be announced on Wednesday chemistry, literature on Thursday, on Friday the peace and economics on Monday.

With a reward of 8 million kronor ($ 1.1 million ), prizes are awarded on Dec. 10, the anniversary of the death of its founder Alfred Nobel in 1896.
