*****Working Principle of Fluorescent Lamp    Heating by current, "filament" of the lamp emits a large number of electrons with great speed from the low potential side to the high   potential side *->collision to argon molecules in the tube during the accelerating process*-> rapid ionization of argon *->produce heat*->   heat produce mercury vapor*-> mercury vapor was ionized *->produce a strong ultraviolet excitation of UV*-> visible light from   phosphors internal. Biggest weakness**-"filament" burns out easily and can not work anymore.


*****Operating Principle"Electrodeless Tube in Tube L" (CCFL- -Cold Cathode Fluorescent Lamp) is a kind of fluorescent lamps, and its lighting principle is similar to fluorescent light. Foremost, enclose the inert gas (Ne-Ar mixed gas) and little amounts of active metal gas in a phosphor coated glass tube; Then, Add a high voltage electric field (high frequency) between the glass tube at both ends of the electrode to produce a gas discharge phenomena; Free-electron emits from the cathode, through a series of energy transport (collision with inert gas), accumulated a considerable degree of kinetic energy, and with the final collision of the low activity metal atoms, electron pass the kinetic energy to atomic excitation; This excited atoms return to ground state, energy absorbed is released in the form of UV (**3.7nm), and the phosphor absorbs the light energy, then change into emitted visible light; Free electrons are continuously accelerated by external electric field; the above process will continue to be in the tubes.In addition, as the process is the conversion of different energy, it must take into account the fit conversion between electrical energy and light. Thus, the rational design of the CCFL power inverter (Inverter) must be pay attention to while using the CCFL.


*****CCFL Voltage CharacteristicIn some cases, voltage characteristic of CCFL and Zener Diodes are very similar, before lighting up, CCFL present infinite   impedance, once lit, is basically a kind of resistive impedance.


Judge from Figure 1, curves can be divided into start-up and working stage. Dotted line on the left is the start-up stage. In the start-up stage, the lamp starts early with weak current. With the increasing of the voltage between the electrodes at both ends of lamp, the internal mercury ion increase quickly with directional movement, which gradually increase the lamp current, when the voltage rose to a certain amount, the lamp started. After starting up, the lamp shows a negative impedance characteristic_the higher the Current, the smaller the voltage across the tube.


In working stage, current decides the brightness, which is shown in Figure 2. Increase of CCFL luminance can be achieved by increasing the current, but the increased current role is limited. Meanwhile, too much current will damage the lamp electrodes, thereby affecting the lamp life.
