Nobel Prize 2014: LED to light up the 21th century

The 2014 physics award went to Isamu Akasaki and Hiroshi Amano of Japan and Shuji Nakamura of the USA, for “the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources.”

According to research, energy consumption of advanced LED lights can be less than one twentieth of ordinary light bulbs, but they durability are 10 times longer than fluorescent lamps and 100 times than incandescent lights, and the lighting effect is more stable.


Because about a quarter of total global power consumption is for lighting purposes, using LED lights will contribute a lot for power savage career. Today, many countries are promoting the LED lighting to save even more power resources required.
