electric component that emits
light when connected to direct

electroluminescent principle and
can emit light in visible specter

ultraviolet. They have
characteristically low energy
consumption, small size, longer
lifetime and faster switching
than incandescence lamps and
because of that, they have a
wide palette of applicability.
