Shuji Nakamura on 2nd and 3rd Generation Solid State Lighting

Shuji Nakamura’s invention to save energy corresponding to about 60 nuclear power stations by 2020

2nd and 3rd Generation Solid State Lighting

For Shuji Nakamura’s invention of high-efficiency GaN double-heterostructure LEDs he was awarded the Nobel Prize in Physics 2014, while his employer sued him in the USA for leaking intellectual property – Shuji Nakamura won this court case, and his employer lost the case. To defend himself and his family, Shuji Nakamura countersued in Japan, and the Japanese court awarded Shuji a substantial award in a settlement. Shuji shared some insights into the comparison of IP lawsuits in US vs Japan with us at the 8th Ludwig Boltzmann Forum.

Shuji moved to the University of California Santa Barbara, and is now building the company Soraa in Silicon Valley with investments from major US VC funds. Soraa may already be or is likely to be soon much bigger in value than Shuji’s previous Japanese employer. Soraa develops 2nd and 3rd Generation Solid State Lighting products.

Energy savings corresponding to 60 nuclear power stations by 2020

The global lighting revolution triggered by Shuji Nakamura’s inventions leads to energy savings corresponding to 60 nuclear power stations by 2020 – 60 nuclear power stations less will need to be built than without Shuji Nakamura’s inventions.

2nd Generation and 3rd Generation Solid State Lighting

With his venture company Soraa, Shuji is now working on 2nd Generation Solid State Lighting (GaN on GaN substrates) and 3rd Generation Solid State Lighting (laser lighting, which allows much higher light density), and which is already in use for car headlights.

Why squeeze Nobel Prize winner Shuji Nakamura into a top-down narrative?

Shuji Nakamura showed with a long list of newspaper clippings, TV show extracts, and Japanese Government agency announcements that he is being squeezed into a top-down innovation narrative, which is at odds with the findings of the Nobel Prize Committee of the Swedish Academy of Science.

Shuji Nakamura asks why he is being squeezed retrospectively into a top-down innovation narrative.

The truth is that most real innovation is bottom-up and disruptive, not government planned and top-down.

At the 8th Ludwig Boltzmann Forum we had intense discussions between Her Imperial Highness, Princess Takamado, Professor Makoto Suematsu, Nobel Prize Winner Shuji Nakamura, Professor Nomura, JST-President Michinari Hamaguchi, and several other Japanese technology and R&D leaders.
