Abstract

A starting circuit for gas discharge lamps, such as fluorescent lamps, includes a relay coil controllable switch. A rectifier-multiplier has its input connectable to the alternating-current mains via the controllable switch. A polarity-reversing switch is coupled to an output from the rectifier-multiplier for supplying direct-current to electrodes of at least one gas discharge lamp. Devices responsive to energization of the mains effect reversal of the polarity-reversing switch upon each energization of the mains. A time-delay relay responsive to each energization of the mains effects the closing of the relay coil controllable switch subsequent to each polarity-reversing action of the polarity-reversing switch.
