Abstract
A quartz protective sleeve surrounding a ceramic metal halide arc tube is supported by a pair of frame members received inside the sleeve. A short frame member extends only partially into the sleeve, while a long frame member extends through the sleeve and includes a loop which engages a dimple at the top of the lamp envelope. The sleeve is fitted over the frame members, which are spring loaded apart. Axial positioning may be provided by terminals or other features fixed to the frame members. In an alternative embodiment, shoulders for positioning the sleeve and terminals for connecting to the arc tube are formed integrally with the frame members.
