Inventors of energy efficient light source win Physics Nobel
Isamu Akasaki and Hiroshi Amano of Japan and US scientist Shuji Nakamura have won the Nobel Prize in physics for the invention of blue light-emitting diodes - a new energy efficient and environment-friendly light source.
The Royal Swedish Academy of Sciences said the invention is just 20 years old “but it has already contributed to create white light in an entirely new manner to the benefit of us all”.
