TRANSFORMER AND STARTING DEVICE HAVING A TRANSFORMER, AND HIGH-PRESSURE DISCHARGE LAMP HAVING A TRANSFORMER

摘要

The invention relates to a transformer for generating a starting voltage for a high-pressure discharge lamp having a ferrite core and at least one primary winding as well as at least one secondary winding, the at least one secondary winding being formed by a metal strip which is arranged on the ferrite core such that the high-voltage carrying end of the at least one secondary winding is arranged on the inside. In addition, the invention relates to a high-pressure discharge lamp, preferably a mercury-free metal halide high-pressure discharge lamp, having such a transformer which is arranged as a starting transformer in the lamp base of the lamp, and to a high- pressure discharge lamp having a transformer which is arranged in the lamp base and whose secondary winding has a DC resistance of less than or equal to 0.5 ohm.
