LED (Light-Emitting Diode)


A semiconductor diode that emits light when charged with electricity. They come in diverse colors and some LEDs even contain multiple elements and are therefore capable of emitting light with different colors.


LEDs are used for displays, for keypad or display backlighting, etc. Bright white LEDs also can be used as flashlights and flashes for mobile phones. Even if they are not as bright as the xenon flash, LEDs are much more compact and require less energy - and also can be used as video light.
