Light emitting diode, or LED, is a semiconductor source of light that emits a particular light colour while passing a current through it. The Colour of light depends on semiconductor doping. LED is a specified type of diode. It allows current in the forwarding direction but blocks in the reverse direction.
LED is the most visible type of Diode and can be seen in almost every electronic device, like TV, & segment, or any type of display device.
LED is designed to emit light and it is made from a very thin layer of doped semiconductor material and the colour of the light depends on the semiconductor. So, when it is biased, emits a wavelength of the particular spectrum.
