    摘要: A discharge lamp has a base with a burner having a discharge vessel with at least two electrodes and a supply conductor extending from the base to one electrode as well as a return conductor extending from the other electrode to the base, wherein the supply conductor is surrounded in the burner by a glass tube while the return conductor extends outside the burner along it, and between the surface of the supply conductor and an inner surface of the glass tube a distance is formed by an air-filled space and retained as low as possible or preferably at least approximately zero, so that the intensity of an electrical field formed between the supply conductor and the return conductor is low and the return conductor can be guided along near the burner, which makes possible a compact construction of the discharge lamp or the use of a high ignition voltage for the discharge lamp and/or its operation at high altitudes without the danger of partial discharges in the glass tube or ark-overs outside the discharge vessel.
