LED (Light Emitting Diode)
|
Light emitting
diodes - diode flashlight Light emitting diodes (LED)
emit light in proportion to the forward current through
the diode. LEDs are low voltage devices that have a
longer life than incandescent lamps.
A light-emitting
diode (LED) is a semiconductor device that emits
monochromatic light of varying colors. LEDs have an
extremely long life span, twice longer than the best
fluorescent bulbs and twenty times longer than the best
incandescent bulbs. |
