Abstract
An HID lamp utilizes a wire frame member having an integral coil with spaces between windings to relieve thermal stress and provide shock absorption in a ceramic metal halide discharge lamp mounted concentrically in an elliptical-dimple (ED-type) glass envelope. The wire frame member has a first end welded to a current carrying support member embedded in the stem and a second end welded to an upper axial lead of the arc tube, the coil being situated about the dimple. The lower axial lead fixed relative to a second current carrying support member embedded in the stem, so that the coil compresses when the arc tube expands relative to the wire frame member.
