Applications of LED:

  • Indicator / pilot lamps on electronic equipment, panels and chargers.
  • Seven-segment and dot-matrix displays (calculators, clocks, meters, scoreboards).
  • General lighting: LED bulbs, tube lights, street lights, torches (high efficiency, long life).
  • Automotive lamps: head lamps, tail/brake lamps, dashboard lights.
  • Traffic signals and sign boards / large video display screens and backlighting of LCD TVs, mobiles.
  • Infrared LEDs in TV remote controls, optocouplers, optical fibre communication, sensors and burglar alarms.

(Reasons: low power, fast switching, long life, small size, many colours.)
