A light-emitting diode (LED)
is a semiconductor light source. LEDs are used are increasingly used for lighting. Introduced as a practical electronic component in 1962] early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with cont.... |

LED Update — Part 1
Solid-state lighting (SSL) is creating a revolution in lighting. Two light sources that constitute SSL (inorganic light-emitting diodes or LEDs and sister technology organic light-emitting diodes, otherwise known as OLEDs) have the potential to replace many light sources that either heat a tungsten filament to incandescence or that use filaments within a glass envelope to create an ionized arc stream, which are cont.... |
