Abstract
PURPOSE: To remove an impairment of a stable lighting due to low temperatures, wherein a series circuit of a charging resistor and capacitor is connected in parallel to a charging resistor of a relaxation oscillator, and a delay time controlling element is provided to form a lighting start compensator.
Starter and supply circuit for fluorescent tubes - has series resonant circuit using current limiting choke for starting and variable resistance for light control
