The Nobel Laureats for Physics 2014 are Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, for having invented a new environmentally friendly, energy efficient light source, the LED. The revolutionary team of Amano and Akasaki working together at the University of Nagoya and Nakamura, employed at Nichia Chemicals, a small company in Tokushima, Japan.
The Alfred Nobel prize rewards inventions of the greatest benefit to mankind, something the LED light does in a multitude of ways.
With almost a fourth of world electricity consumption estimated to be for lighting purposes, changing over to LEDs fundamentally contributes to saving the Earth’s resources. LEDs last up to 100,000 hours, compared to 1,000 for incandescent bulbs and 10,000 hours for fluroescent lights, also reducing the quantity of materials required.
In addition to this, the LED has lower power requirements, something that can improve the quality of life for the 1.4billion people around the world who do not have access to electricity grids as these type of lamps have lower power requirements.
