LED (Light Emitting Diodes) are the latest and most exciting technological advancement in the lighting industry. LED is a semiconductor device that emits visible light when electrical current passes through it, it is a special kind of diode. LEDs are small, solid light bulbs which are extremely energy-efficient and long-lasting. LEDs operate differently than traditional incandescent light bulbs. This makes LEDs far more rugged and durable than traditional incandescent light bulbs. LED technology also offers many additional advantages over incandescent, neon, and compact fluorescent lighting devices – such as an exceptionally longer life span (60,000 hours), enormously lower energy usage (90% more efficient), reduced maintenance costs, and higher safety. LEDs are currently being used for a wide variety of applications such as residential lighting, aerospace, architectural lighting, automotive, aviation, broadcasting, electronic instrumentation, entertainment and gaming, industrial automation and controls, the military, traffic, and safety & transportation.
