a light emitting diode led is a semiconductor device that emits visible light when an electric current passes through it the light is not particularly bright but in most leds it is monochromatic occurring at a single wavelength
A light-emitting diode (LED) is a two-lead semiconductor light source. It is a pân junction diode that emits light when activated. When a suitable current is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.
