LEDs, the most efficient lights on the market, are starting to appear alongside incandescent and compact fluorescent bulbs in hardware and home-goods stores. They are, however, a mystery to many, as their inner workings are quite a bit different from standard bulbs.


What is light-emitting diode ?

A diode is an electrical device or component with two electrodes  through which electricity flows - characteristically in only one direction . Diodes are generally made from semi-conductive materials such as silicon or selenium




What is LED Lighting?

A light-emitting diode is a semiconductor device that emits visible light when an electrical current passes through it. It is essentially the opposite of a photovoltaic cell (a device that converts visible light into electrical current).




How They Work?

Connecting a diode to an electrical current excites the electrons within the diode, making them release photons, which we see as light. The color of the light is a direct result of the energy gap in the semiconductor of the diode. This means that LEDs produce a spectrum of colors easily and brightly while using very little electricity to do so.


Importance

In the search for energy-efficient lighting, LEDs have proven to be the most efficient bulbs available. energy-efficient Label LEDs use at least 75 percent less energy than traditional incandescent bulbs and last 25 times longer,. LEDs even outdo CFL (compact fluorescent lighting) bulbs in efficiency, primarily because they have twice the lifespan of CFLs. LEDs are more efficient than both incandescents and CFLs because they emit light in a targeted direction — instead of scattering it in all directions — and they don't require or emit great amounts of heat. Incandescents and CFLs release most of their energy as heat — 90 percent and 80 percent, respectively


Features of LED Lights


 

  • -         Environmentally Friendly 
  • -         LED lighting is non-toxic and contains no mercury, lead or cadmium, and is recyclable 
  • -         Immediate reduction of power consumption. 
  • -         Reduced recycling costs required to dispose of hazardous bulbs and ballast. 
  • -         Durable Quality 
  • -         LEDs are extremely durable and built with sturdy components that are highly rugged and can withstand even the roughest conditions. 
  • -         Individual LEDs can be dimmed, resulting in a dynamic control of light, color and distribution. 
  • -         Save Money

Over the lifetime of one LED light, you will save 200SR or more on your electricity cost alone. Image the savings if every light in your home was an LED light!
