Patent ID: 7952284

Claim:
A metal halide lamp comprising a ceramic discharge vessel which encloses a discharge space, first and second electrodes arranged in the discharge space, wherein the ceramic discharge vessel has a central zone extending between the electrodes and being closed at either side by a first and a second end zone, respectively, a first current supply conductor surrounded by the first end zone with clearance equal to or less than 0.3 mm, wherein the first current supply conductor is connected to the first electrode and extends to the exterior through a seal to the wall of the first end zone, the first current supply conductor comprising a halide-resistant section facing the discharge space and a section adjacent to the halide-resistant section and remote from the discharge space, wherein the section adjacent to the halide-resistant section and remote from the discharge space is completely encompassed by the seal and is not exposed to the discharge space through the first end zone clearance, the halide-resistant section of the first current supply conductor comprising a wire made of molybdenum alloyed with from 10 to 20% by weight of tungsten.
