Q:How are LEDs different from other light sources in the way they emit light?

     A:LEDs emit light by converting electrical energy directly into light energy. Incandescent lamps emit light by heating the filament until it turns red. Linear and compact fluorescent lamps use ultraviolet discharge and phosphors to produce light. HID lamps produce photons by ionizing gas in the discharge tube.
