Electroluminescent Lighting


Electroluminescence is the Optical and Electrical phenomenon in which a material emits light when current passes through it. This phenomenon is entirely different from the emission of light from bulbs and other light emitting devices. It is resulting from the radiative recombination of electrons and holes in a semi conductor material. The excited electrons generate Photons to give light. LEDs and Phosphor displays are typical examples of electroluminescent lighting.

Compact Fluorescent Lamp


Compact Fluorescent Lamp or CFL is the energy saving lamp designed to provide adequate light at the expense of low current.CFL uses less power around one fifth of an ordinary bulb and has long life.CFL is designed to emit Soft white light using the phosphor formulations.CFL comes in two forms like integrated and non integrated CFLs. In integrated type, the tube combines with an electronic ballast as a single unit while in non integrated type, ballast and tube are separate units so that the tube can be replaced.AC and DC CFLs are available.CFL generally has a life span of 6000 to 20000 hours.
