Nobel 2014
foundational GaN LED science
The blue LED that made all of this possible.
In 2014, Shuji Nakamura shared the Nobel Prize in Physics for inventing the efficient blue gallium-nitride LED, the breakthrough that made white LED lighting possible at all.
That lineage runs directly into OIO. The foundational GaN and spectral-engineering IP from Soraa, the company Nakamura co-founded, is now part of Korrus (Ecosense Lighting). The ability to place light energy exactly where you want it in the spectrum, and take it out of the melanopic band at night, is the product of that work.
The lineage
- 1Nakamura, 1990s. Efficient blue GaN LED (Nobel, 2014).
- 2Soraa. GaN-on-GaN + full-spectrum LED engineering.
- 3Korrus / Ecosense. 500+ patent portfolio, circadian + spectral.
- 4OIO. That spectral control, in a $70 bulb.

Defensible by design.
Anyone can dim a bulb and call it circadian. Doing what OIO does, hitting the same visible color from a spectrum engineered to be quiet in the melanopic band, is protected work built over a decade. That is why it holds up when you measure it, and why competitors cannot simply copy the marketing.
