    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.

    摘要: A rod-core transformer for use as a starting transformer in the cap of a high-pressure discharge lamp for a motor vehicle headlight. The rod-core transformer has at least two cores (2, 3) which are in the form of rods and are arranged alongside one another, and on each of which a multilayer secondary winding (4, 5) is wound, with the respective layers (4a, 4b, 4c, 4d) and (5a, 5b, 5c, 5d) being connected in parallel and being arranged one above the other without any offset. Furthermore the secondary windings (4, 5) are electrically conductively connected to one another, with their total resistance being at most 2&OHgr;. The transformer is particularly highly suitable for use as a starting transformer for high-pressure discharge lamps with a low operating voltage, for example halogen metal-vapor high-pressure discharge lamps which do not contain mercury.
