Inventors of LED light win physics Nobel

The three scientists responsible for allowing governments to ban most incandescent light bulbs by inventing the LED have won the Nobel Prize in physics. Reuters: An American and two Japanese scientists won the 2014 Nobel Prize for Physics on Tuesday for inventing a new energy-efficient and environment-friendly light source, leading to the creation of modern LED light bulbs. Isamu Akasaki and Hiroshi Amano of Japan and Japanese-born U.S. citizen Shuji Nakamura won the prize for developing the blue light-emitting diode (LED) -- the missing piece that now allows manufacturers to produce white-light lamps. The arrival of such lamps is changing the way homes and workplaces are lit, offering a longer-lasting and more efficient alternative to the incandescent bulbs pioneered by Joseph Swan and Thomas Edison at the end of the 19th century. "Red and green LEDs have been around for a long time but blue was really missing. Thanks to the blue LED we now can get white light...(Read Full Post)
