Isamu Akasaki and Hiroshi Amano of Japan, along with Shuji Nakamura of the University of California, received the Nobel Prize in Physics on Tuesday. The trio invented "efficient blue light-emitting diodes," and their invention "has enabled bright and energy-saving white light sources," according to the Nobel Academy.
The Nobel Academy added that the light-emitting diodes, a.k.a. LEDs, were "revolutionary," because the LED lights save energy and are long-lasting.
