WebA light-emitting diode (LED) is a type of diode that allows current to only pass through it in one direction and when a current passes through it, it will emit light. Many LEDs can be used for illumination whereas a single LED can be used to indicate a current passing through an electrical component. WebA Light Emitting Diode (LED) is a semiconductor device, which can emit light when an electric current passes through it. To do this, holes from p-type semiconductors recombine with electrons from n-type semiconductors to produce light. The wavelength of the light emitted depends on the bandgap of the semiconductor material.
