<p>Disclosed herein is a method of driving a fluorescent light which divides the phases of input AC power depending on voltage magnitude and utilizes the low-voltage portions of the divided voltages as heating power for heating filaments, and the high- voltage portions of the divided voltages as the discharge voltage of the fluorescent tube in a heat and discharge type fluorescent light, thus lengthening the lifetime of the fluorescent light, improving the illuminance of a fluorescent tube, and improving the efficiency of power use due to the elimination of need for power transformation, and a ballast stabilizer circuit for performing the same. The present invention receives and full- wave rectifies commercial AC power, divides the phases of the full-wave rectified AC power depending on voltage magnitude, and performs switching control such that low-voltage portions of the divided voltages having low phases are used as heating power for heating filaments of a fluorescent tube, and high- voltage portions of the divided voltages having high phases are used as discharge voltage of the fluorescent tube. As a result, the present invention directly supplies required power using the difference of voltage caused by the phases of AC power with only a simple switching operation and without voltage transformation.</p> |
