Inventors of blue LED win Nobel Prize

7 October 2014 12.30 BST


(Norway) - Trio of scientists win this year’s Nobel Prize in physics for their invention of blue LED.

The 2014 Nobel Prize for physics has been awarded to three scientists in Japan and the US for inventing blue LED, one of the most crucial leaps forward made in the lighting industry in recent times.

Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, one of the founders of Soraa, were singled out by the Nobel Institute for inventing “a new energy-efficient and environmentally friendly light,” that offers a, “more long-lasting and more efficient alternative to older light sources.”

The Institute also noted that when the professors “produced bright blue light beams from their semi-conductors in the early 1990s, they triggered a fundamental transformation of lighting technology.”

In the citation the Institute concludes that, "incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.”

The winners will share prize money of eight million kronor (£0.7m).
