Series*******-CCFL
*****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 ÂÂ
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.
