The inventors of blue LED light, Nobel Prize in Physics 2014, for being “a new source of light to illuminate the world”

The inventors of blue LED lights: the Japanese Isamu Akasaki, Hiroshi Amano and Shuji Nakamura have been awarded the Nobel Prize in Physics 2014 for creating “a new light to illuminate the world, a new source of efficient and environmentally friendly energy”, as stated in the statement from the Swedish Academy of Sciences.

Blue LED lights, an efficient and environmentally friendly light source, has been distinguished, through its inventors, scientists and university professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, with the Nobel Prize in Physics 2014, according to the announcement made by the permanent secretary of the Royal Swedish Academy of Sciences, Steffan Normak, in an appearance broadcast live by the organization of the Nobel Prizes on tuesday 7 October.

This prestigious award recognizes LED (light emitting diode) as “a new efficient and environmentally friendly source of energy”, according to the statement issued, which is part of “the spirit of Alfred Nobel” to create inventions that “contribute great benefit to Humanity”, and the LED “is ​​a new light to illuminate the world”.

Japanese scientists Isamu Akasaki, Hiroshi Amano and Shuji Nakamura (with American nationality) invented blue LED lights in the early 1990s 90, since until now only red and green light-emitting diodes were known, and hence its distinction to achieve “a fundamental transformation of lighting technologies”, as the Academy points out, to “generate white light in a new way thanks to the invention of blue LED light, which had been a challenge for three decades. With the arrival of LED lamps we have more durable and efficient alternatives to old light sources”.

In this sense, The statement from this institution highlights that the work carried out by these three scientists “has succeeded where everyone else had failed” and they emphasize that their inventions “have been revolutionary.”. “Incandescent light bulbs illuminated the 20th century and the 21st century will be illuminated by LED lamps.”.

Energy efficiency, Durability and respect for the environment have been other arguments that the Royal Swedish Academy of Sciences have highlighted regarding the granting of this award., with special emphasis on the benefits to improve the quality of life of the population: “LED lamps are a clear promise to improve the standard of living for more than 1.500 millions of people around the world who do not have access to electricity grids: Due to the low consumption they require, they can be powered by local solar plants.”.

The Nobel Prize in Physics is endowed with eight million crowns (882.000 euros), which will be distributed equally among the winners. The Nobel Prize ceremony will take place, as tradition marks, the next 10 December, anniversary of the death of Alfred Nobel, in Stockholm.
