This year's Nobel Prize for Physics has been awarded jointly to the inventors of the blue LED which was the key breakthrough that made LED lighting possible and has given us the power to significantly reduce global electricity consumption.

While green and red diodes have been around since the 1950s, creating blue-emitters was a technical challenge that stumped industry efforts for decades. It was not until the 1990s that engineers Isamu Akasaki and Hiroshi Amano, both at Japan’s Nagoya University, in parallel with electrical engineer Shuji Nakamura, then working at Japanese chemicals firm Nichia, succeeded in creating a blue LED.

Their success in overcoming those hurdles opened the door to white LEDs, which can have efficiencies nearly 20 times those of conventional bulbs.

As approximately one fourth of world electricity consumption is used for lighting purposes, LEDs contribute to saving the Earth’s resources. Materials consumption is also diminished as LEDs last up to 100,000 hours, compared to 1,000 for incandescent bulbs and 10,000 hours for fluorescent lights.

The Nobel Prizes aim to recognise developments that have brought the greatest benefit to mankind. The award for the Japanese scientists represents a major endorsement of the significance of the LED lighting revolution, and the technology's potential to make the world a better place.

At Schréder, we have always been passionate about designing energy efficient solutions that provide safety and comfort for all. We are delighted to be at the forefront of this LED lighting revolution that is transforming the way in which our towns and cities are lit and is estimated to help save up to 20% of the global electricity consumption.” comments André Papoular, CEO of the Schréder Group.
