Abstract:
A stabilizer for multiple light sources, using a Rosen type Piezoelectric Transformer with multiple output electrodes, comprising:a rectifying section rectifying AC commercial electric power source to DC electric power; a power factor compensation section compensating the power factor caused by the fluctuation of the voltage of AC commercial electric power source so as to maintain the voltage of DC electric power generated from the rectifying section in uniform level; AC voltage generating section converting the DC power inputted from the power factor compensation section to AC electric power having a predetermined frequency; and a Rosen type Piezoelectric Transformer with multiple output electrodes having a identical band shape, wherein the output electrodes is arranged in parallel to a input electrode, have an equal distance between neighboring electrodes, are electrically connected to a plurality of cold cathode fluorescent lamps respectively; whereby identical voltages are applied simultaneously to a plurality of fluorescent lamps.
