This work revolutionized the field of lighting technology, as blue LEDs made it possible to create white light sources that were much more energy efficient than traditional incandescent bulbs.

In 2014, Nakamura, with fellow researchers Akasaki and Amano, was awarded the Nobel Prize in Physics for the invention of the blue LED. This was the first time that the Nobel Prize in Physics had been awarded for a discovery in the field of solid-state lighting.

Blue LEDlight history

Blue LED LightsStrips

The first LED (Light Emitting Diode) was invented in the 1920s, but it wasn't until the 1960s that the first LED displays were created. These early displays were very basic and could only display simple text and numbers.

With the combination of these three colours, you can produce all the colours imaginable. Red and green LEDs were already available for a while, but blue was harder to find.

Blue LEDlight for skin

There was a decade long search for a reasonably bright and affordable blue LED (Light Emitting Diode). Not to pimp game computers, but it was the missing colour in Red, Green and Blue. Or RGB.

Despite facing numerous obstacles and setbacks, Nakamura was persistent in his efforts and continued to experiment and refine his approach until he finally succeeded in producing blue LEDs.

This is a story about a determined team in Japan that kept looking for something many had stopped looking for: a blue LED light.

Shuji Nakamura was driven by a strong scientific curiosity and a desire to push the boundaries of what was thought possible. He was also motivated by the challenge of finding a solution to a problem that many other researchers had been unable to solve.
