Happy 50th Birthday LED

October 12, 2012

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:
