Ignition voltage generating circuit arrangement for e.g. low pressure discharge lamp, has circuit branches switched parallel to lamp, where ignition voltage for lamp is generated based on transformer effect at inductor

摘要

The arrangement has an inductor (2) and a switch (5), which are electrically connected with the respective lamp coils (11,12). Circuit branches (3,4) are switched parallel to an electric discharge lamp (1). A current flow is generated through the circuit branches based on the switch position, such that a transformer effect is produced at the inductor. The ignition voltage for the discharge lamp is generated based on the transformer effect.
