Three Japanese scientists Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura have been honored with this year’s Nobel Prize in Physics for their activities in creating the LED light. Shuji Nakamura is a scientist at the University of California in Santa Barbara, and together with his contemporaries in the Physics world; they have perfected the LED light where earlier other scientists had failed.

The award committee has chosen these three to be this year’s winners for Physics because, according to them, the trio has developed LED lights that ushered in a new energy and environmentally-friendly light source. Almost everyone the world over now uses a LED light that is more energy-friendly and environment-friendly, and this is largely because the three physicists perfected the LED light technology.

The three physicists were particularly awarded the honor for their efforts at inventing the blue light emitting diode. Green and red diodes have been around for decades, but these three perfected the blue diodes that “triggered a fundamental transformation of lighting technology.”

A Nobel Prize award comes with a $1.2 million prize, and this prize is available for each category of award. Francois Englert of Belgium and Peter Higgs of the UK were awarded last year’s Nobel Prize in Physics because they perfected the theory of how particles acquire mass. Later this week, the award committee will announce the Nobel Prize award winners for Chemistry, Literature, and Economic sciences.
