| 摘要 |
The invention relates to a high-pressure discharge lamp of the ceramic metal halide type of the Philips MasterColor series having power ranges of about 150 W to about 1000 W. Such lamps are provided with outer bulb (10) enclosing a cylindrical ceramic discharge vessel (20) enclosing a discharge space, said cylindrical ceramic discharge vessel including within said discharge space an ionizable material comprising a metal halide; a first and second discharge electrode feedthrough means (30, 40); and a first and second current conductor (12, 13) connected to said first and second discharge electrode feedthrough means (30, 40), respectively. The lamp has a single substantially curved frame wire (17), connected to one of the current conductors (12, 13), extending between the ceramic discharge vessel and the glass bulb, and being separated from the discharge vessel by a distance effective to reduce at least one and preferably both arc bending and temperature of the frame when compared to a discharge lamp wherein the frame wire extends substantially parallel to the ceramic discharge vessel.
