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 special kind of diode that glows when electricity passes through it. Most LEDs are made from a semi-conducting material called gallium arsenide phosphide. LEDs can be bought in a range of colours. They can also be bought in forms that will switch between two colours (bi-colour), three colours (tri-colour) or emit infra-red light. In common with all diodes, the LED will only allow current to pass in one direction.
