In this audio BBC Witness History talks with Shuji Nakamura, the inventor of the LED lightbulb in 1992. Nakamura shows the resilience and stubborn persistence against the odds that has given the world an extraordinary invention. The LED bulb does great things for climate change action because for example Califonria uses 35% of its electricity for lighting. The LED bulb cuts this in half and this means many coal fired power plants are not needed. In India, Indonesia and China this means lighting for about 3 billion people, with lighting for children studying in remote parts of India and China, and in Africa and Latin America. Nakamura took an unconventional route. He did his PhD in Japan not by going to school which is allowed in Japan, but by writing a paper on White LED development. He made a single minded focus on this goal. Nakamura says it made him angry that no one wanted to try new ideas and he persisted for years of research. At the time GaN research was done by less than one percent of researchers. Nakamura decided to try the path less trodden and by 1992 developed a blue light emitting LED bulb. Add phospor particles and blue becomes bright white LED. ...
