What are LEDs?
LED is the acronym for Light-Emitting Diode. A diode is an electronic semi-conductor component that allows an electric current to flow in one direction and blocks current flow in the opposite direction. An LED is a diode consisting of a semi-conductor chip constructed in a way that generates photons to emit energy in the form of light when an electric current passes through it.
Compared to conventional light sources that first convert electrical energy into heat, and then into light, LEDs convert electrical energy directly into light, delivering efficient light generation with little-wasted electricity.
