Operating Principle of CCFL 

A cold cathode is a cathode, an electrode that emits electrons, which is not electrically heated by a filament. They are used in gas discharge lamps such as neon lamps, discharge tubes, and some types of vacuum tube. The other type of cathode is a hot cathode, which is heated by electric current passing through a filament. A cold cathode does not necessarily operate at a low temperature; it is often heated to its operating temperature by other methods, such as the current passing from the cathode into the gas. Cold Cathode Fluorescent lamp which has been used as backlighting for LCD displays, computer monitors, television screens and sanners for many years ※ A more detailed explanation of Induction Lighting, please visit Wikipedia.
