Physics Nobel For Lighting Up Our World

Physics nobel prize winner Isamu Akasaki and Hiroshi Amano from Japan and Japanese-born American scientist Shuji Nakamura have won the Nobel prize for physics their invention of blue light-emitting diodes - a revolutionary work that led to the LED technology, which lights up homes and offices and the screens of mobile phones, computers and TVs. The lamps based on the LED technology not only consume much lesser power but also last much longer than the flourescent or even CFL lamps.

 

. The lamps based on the LED technology not only consume much lesser power but also last much longer than the flourescent or even CFL lamps.

Often in physics, the prize is awarded for understanding the very small or the very distant: a light that removes our ignorance. But this time, by contrast, the physics prize is for an actual light that has already conferred great benefit on mankind, and promises yet more.


It would be hard to count all the applications that use blue LEDs, principally because they are joined with green and red lights to make the light which people see: white. LED-based lighting is finding its way more and more as it becomes cheaper.
