(54) Light-source capsule containment device and lamp employing such device


(57) A light-source containment device and lamp employing such device; a metal halide arc discharge lamp having a light-transmissive shield enclosing the arc tube and a wire mesh surrounding the shield. In the event the arc tube bursts causing shattering of the shield, the wire mesh substantially restricts shards of the shield and arc tube from shattering the outer envelope of the lamp thereby providing improved safety characteristics of the lamp. A similar containment device encloses the light-source capsule and protects against lamp-containment failures in tungsten halogen lamps.
