Nobel Prize in Physics awarded to the creators of the LED bulbs

Isamu Akasaki and Hiroshi The Amano Japanese scientists and an American of Japanese origin Shuji Nakamura have been awarded the Nobel Prize in Physics for his invention of the blue LED lights (acronym corresponding to the name of Light Emitting Diodes), which allowed get "sources and energy-saving bright white light."
The announcement of the award has made this Tuesday morning the permanent secretary of the Royal Swedish Academy of Sciences, Steffan Normark, in a hearing broadcast live on the organization of the Nobel Prizes.
The Swedish Academy of Sciences explained in a statement that this year has rewarded the invention of a "new source of energy efficient and friendly to the environment."

An alternative efficient and durable lighting
"In the spirit of Alfred Nobel, the award recognizes an invention that provides a great benefit to mankind: using blue LED lights, white light can be generated in a new way. With the advent of LED lamps have longer lasting and more efficient alternatives to the ancient sources of light, "he said.
The Academy has stressed that the invention of Akasaki, Amano and Nakamura teachers early 90s has been "a fundamental transformation of lighting technologies." "The green and red LEDs have been around for quite some time but without the blue light, white lamps could not have been created. Despite considerable efforts in both industry and the scientific community, the blue LED lights had been challenging for three decades, "he explained.

The LED lights illuminate the XXI century
The Swedish institution stressed that these three professors have succeeded "where they had all failed." Specifically, Akasaki worked with Amano in Nagoya University in Japan, while Nakamura did his research in the Japanese company Nichia Chemicals, a small firm of Tokushima. "His inventions were revolutionary. Incandescent bulbs lit the twentieth century; the twenty-first century will be illuminated by the LED "lamps, has predicted the Academy.
In this regard, he assured that the LED lamps emit white light using energy efficiently and are durable, well be improving their capabilities "constantly". This steady progress has allowed to reach a record of more than 300 lumens-watt compared to 16 a bulb and fluorescent 70.
The Sweden Academy of Sciences pointed out that the LED lights help to "save the Earth's resources," since they are rated at 100,000 hours compared to 1,000 hours for incandescent bulbs and fluorescent 10,000 lives.
"LED lamps it is a clear promise to improve living standards for more than 1,500 million people worldwide who lack access to electricity grids due to low consumption required can be fed by local solar plants," he explained.
Finally, the Royal Swedish Academy of Sciences has stated that the blue LED light was invented 20 years ago "just" but "has already helped create white light in an entirely new way to benefit everyone."
Born in Chiran (Japan) in 1929, Isamu Akasaki is a doctor and distinguished professor of Nagoya University and professor at Meijo University. Hiroshi Amano, born 1960 in Hamamatsu (Japan), is also a doctor and distinguished professor of Nagoya University. Meanwhile, Shuji Nakamura has American nationality but was born in Ikata (Japan) in 1954 In addition to being a doctor of the University of Tokushima, a professor at the University of California, Santa Barbara (USA).
The Nobel Prize in Physics is equipped with eight million kronor (882,000 euros) to be shared equally among the winners.
