ABSTRACT:
A gas-discharge lamp igniter is disclosed which has a group of gas-discharge lamps, such as those for LCD backlighting, connected in parallel with one another between the pair of outputs of an AC power supply. Provided one for each lamp to be energized, current-balancing transformers have their secondary windings serially interconnected. The lamps are connected to one of the pair of outputs of the AC power supply via the respective primary windings of the current-balancing transformers and the serial connection of the secondary windings thereof.
