A power supply and firing control circuit for a strobe lamp has a capacitor means for providing electrical power to the power electrodes of the strobe lamp for discharge through the strobe lamp. A transformer has a pair of secondary windings, one of which is connected to each of the power electrodes of the strobe lamp in series with the capacitor means. The firing pulses provided by the secondary windings of the transformer are of opposite electrical polarity. The absolute voltage differential between any portion of the circuit and ground potential will be minimized and energy losses thereby reduced. Additionally, the circuit provides substantial improvement in ionization effectiveness, thereby permitting the secondary turns of the transformer to be reduced in number and the transformer size and weight reduced correspondingly. |
