Nobel Prize for Inventors of Blue LEDs Who Gave Us White Light

The 2014 Nobel Prize for Physics has been awarded to 3 scientists who invented blue LEDs.

In the early 1990s red and green diodes had been around for a long time but without blue light, white  light could not be created. Despite big efforts, the blue LED had remained a challenge for three decades and its invention triggered a fundamental transformation of lighting technology.

This recent article in Fortune magazine suggests that LEDs are the death knell for Edison’s incandescent light bulb.
