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 very basic introduction to how a light-emitting diode works. In the simplest terms, a light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is produced when the particles that carry the current (known as electrons and holes) combine together within the semiconductor material. Since light is generated within the solid semiconductor material, LEDs are described as solid-state devices.
