LED lights.LED stands for Light Emmiting Diode. LEDs work on the concept of the semiconductor diode. When the diode is on,the electrons combine with holes resulting in emmission of energy in the form of light.The colour of the light is influenced by the energy gap of the semi conductor.LEDs are advantageous in that they consume…
