The invention of the white LED lightbulb

In 1993, a literal lightbulb moment led to the invention of the first white light emitting diode (LED). These LEDs are now used to light up everything from our streets to our homes to this screen you’re looking at. Along with two other Japanese engineers, Professor Shuji Nakamura, was behind this illuminating invention. But Shuji’s journey to this point is one of resilience and perseverance. In his pursuit to discover the first commercial white LED, he had to overcome many obstacles along the way. With less funding than his counterparts and one of the only inventors without a PhD degree, Shuji stood out from the crowd. He set out to get his PhD degree and found one of the most sought-after inventions along the way. Professor Shuji Nakamura speaks to Natasha Fernandes about finding the light and how it might not be what you would expect.
