LED LIGHTS, LED LIGHTS DESIGN, LED LIGHTS TRADERS

LED LIGHT
         A light-emitting diode (LED)  is a semiconductor light source. LedLights are used as indicator lamps in many devices, and 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 very high brightness.When a light-emitting diode is forward biased (switched on), electrons are able to recombine with holes within the device, releasing energy in the form of photons

  1. how can u say When a light-emitting diode is forward biased (switched on), electrons are able to recombine with holes within the device, releasing energy in the form of photons.
