CIRCUIT ARRANGEMENT FOR A STARTING UNIT OF A DISCHARGE LAMP

摘要

The invention relates to a circuit arrangement for a starting unit of a discharge lamp (1) having a spark gap, which is formed from three or more electrodes (11) and which is connected in series to the primary winding (8) of a superimposed transformer (3) and to a pulse capacitor (9). The invention provides that the electrodes (11) have a cylindrical design, the cylinder axes (12) being situated adjacent and parallel to one another and, to be precise, in such a manner that a multistage spark air gap is formed perpendicular to the cylinder axes (12). The invention also relates to a starting unit for a high-pressure discharge lamp.
