(57) An electronic ballast stabilizer for a florescent lamp comprises a noise reduction
transformer and capacitors, a bridge rectifying circuit, a noise reduction circuit,
two switching transistors, voltage regulating coils, a constant current transistor,
a center tap and a chopper transformer. A fine low frequency voltage wave is oscillated
from the chopper transformer and simultaneously an automatic oscillated sound is biased
so that the lamp is turned on under low current and the wavelength is constant.
