    Abstract: A circuit (500) for driving series-connected gas discharge lamps from a transformer secondary winding (528) connected at first (529A) and second (529B) points respectively to first (508) and second (514) output terminals across the lamps. A capacitor (532) couples the first point to an intermediate output terminal (512). The pre-strike voltage produced across the secondary winding is applied across a single lamp (506) to cause it to strike. After striking, current to the intermediate output terminal (512) is limited by the capacitor (532), and the lamps are driven in series. In this way, the voltage which needs to be produced across the secondary winding to ensure striking of all lamps is reduced. Alternatively, the output terminals across the lamps may be connected to points on the secondary winding further apart than the first and second points (Fig. 6) or intermediate the first and second points (Figs. 1-4).
