An LED, or Light Emitting Diode, is a two-lead semiconductor that emits light when the proper voltage is applied. While LED lighting has been around for many decades, technological advancements over the past 10 years have allowed this technology to completely revolutionize the lighting industry.
LED technology was first discovered in 1927 by Oleg Olsev, and was later revolutionized by Nick Holonyak, Jr. while he was working in a Syracuse, NY research laboratory. Mr. Holonyak is credited with creating the first visible spectrum LED. In the February 1963 issue of Reader’s Digest, Holonyak made a prediction that one day LED’s would replace incandescent lamps, which had been invented by Thomas Edison. Today, LED’s are being used in almost every application conceivable, from car headlights and computer monitors, to area and roadway lighting.
