The blue LEDs fathers receive the Nobel Prize in Physics – evertiq.se

Three will share this year’s Nobel Prize in Physics for his work with blue LEDs and the revolution it meant.

The Royal Swedish Academy of Sciences has now gone out with who will be the winner of the Nobel Prize in physics anno 2014: Isamu Akasaki Hiroshi Amano and Shuji Nakamura received the prize for “the invention of efficient blue LEDs has enabled bright and energy-efficient white light sources.”

The motivation reads among other things, that the blue LEDs allows light sources that last longer and are more efficient than older types of lighting. For three decades, researchers struggled with trying to create the blue light but these three men succeeded where others failed. When Isamu Akasaki Hiroshi Amano and Shuji Nakamura produced blue light beams from semiconductors in the mid-1990s, they started a revolution in the lighting world. Red and green LEDs have been around a long time but without the blue light had the lighting was not possible to get to, you write on.

Since about a quarter of the world’s electricity is used for lighting purposes, the LEDs help to save the earth’s resources. Material consumption will also decrease as the LEDs operate at up to 100’000 hours, compared to 1’000 for light bulbs and 10,000 hours for fluorescent lamps.

To quote the Royal Academy of Science: “The ordinary light bulb lit up throughout the 1900s; LED will light up the 2000′s. “
