Happy 50th birthday to the LED
The 50th anniversary of the birth of the LED is being celebrated at the University of Illinois with participation from the LED inventor himself, Nick Holonyak Jr.
On the 9th of October 1962 Holonyak, who was then a consulting scientist at General Electric, demonstrated the first practical, visible spectrum LED at the company’s advanced semiconductor laboratory in Syracuse, New York. This first III-V alloy PN junction design is the prototype for all high-brightness LEDs made today.
Many of the researchers who studied under Holonyak have subsequently refined the technology, through improvements in crystal manufacturing techniques, to develop bright-light LEDs in every colour, including white.
