  • (B) Light Emitting Diode

  • (D) Low Emission Data
LED stands for Light Emitting Diode. It is a semiconductor-based light source that emits light whenever an electric current is passed through it. This is because of a process called electroluminescence, which occurs when electrons recombine with holes in a semiconductor, resulting in the emission of photons. LEDs are known to be energy-efficient because they convert a large amount of electrical energy directly into light, with very little heat being produced, unlike traditional incandescent bulbs.
