摘要

A metal halide lamp comprising a discharge vessel (10) having a translucent ceramic wall enclosing a discharge space (11). The vessel (10) has a cylindrical shape having its largest outer diameter in its central part (12). Two coaxial electrodes (15,16) are embedded in the end parts (13,14) of the vessel (10). The lamp furthermore comprises an outer envelope (5) surrounding the discharge vessel (10), and a current conductor (20) is present between the discharge vessel (10) and the wall (22) of the outer envelope (5). The current conductor (20) is provided with a support member (21) having a contact surface for abutting against the discharge vessel (10).
