Three scientists share the Nobel physics prize for inventing blue LED lights.
The prize goes jointly to Isamu Akasaki of Meijo University in Nagoya, Japan, Hiroshi Amano of Nagoya University in Japan, and Shuji Nakamura of the University of California, Santa Barbara. Starting in the 1990s they produced blue LEDs, an energy-efficient, environmentally friendly source of blue light, which could be mixed with LEDs of other colors to produce what the eye sees as white light. “I am very honored to receive the Nobel Prize from The Royal Swedish Academy of Science for my invention of the blue LED,” said Nakamura in a statement. “It is very satisfying to see that my dream of LED lighting has become a reality. I hope that energy-efficient LED light bulbs will help reduce energy use and lower the cost of lighting worldwide.”
