In October 1962, scientist Dr. Nick Holonyak invented the first light emitting diode (LED). The light, unlike infrared lasers, is visible to the human eye, and has a higher efficiency compared to other lighting technologies.
Fifty years later and LED is fast becoming popular among businesses for its low energy and maintenance costs.
Holonyak, now a University of Illinois professor, said, “I know that I’m just at the front end but I know the result is so powerful… there’s no ambiguity about the fact that this has got a life way beyond what we’re seeing.”
Holonyak also took the time to film the short interview embedded below:
