Nobel prize for physics 2014 goes to inventors of energy-efficient LED light

LONDON: The invention of an energy source that lights up our computer and/or mobile phone screens and holds promise to brighten up the quality of life of over 1.5 billion people around the world, has been awarded the Nobel prize for physics 2014.
Announcing that "this year's Nobel prize for physics is about light", the Royal Swedish Academy of Sciences decided to award the most coveted prize to three Japanese scientists — Isamu Akasaki from Meijo University, Hiroshi Amano from the Nagoya University, Japan and Shuji Nakamura from the University of California "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources."
The laureates were rewarded for having invented a new energy-efficient and environment-friendly light source — the blue light-emitting diode (LED).
According to the committee, the laureates' inventions revolutionized the field of illumination technology.
New, more efficient, cheaper and smarter lamps are developed all the time. White LED lamps can be created in two different ways. One way is to use blue light to excite a phosphor so that it shines in red and green. When all colours come together, white light is produced.
