No comments · Posted by admin in Uncategorized
Heres an interesting article on the history of LEDs by the BBC!
The light-emitting diode has brightened our lives for half a century – from lighting up the city streets at night, to decorating Christmas trees each December.
The LED started life in October 1962, as a single red illumination in a General Electric research lab in New York state.
Now – as one of the world’s biggest retailers, Ikea, announces that by 2016 the only lighting products it will sell will be LED-based ones – Prof Nick Holonyak Jr from the University of Illinois, takes a look back at how it all began with his invention of the first practical visible-spectrum light-emitting diode.
