An arc discharge lamp having a sealed envelope including at least two longitudinally extending leg members spaced a predetermined distance thereapart and joined together by a transversely extending envelope portion. Support spacer means formed from the envelope (e.g., by blow molding) prevents breakage of the transversely extending envelope portion caused by inward deflection of the leg members. Preferably, the support spacer means includes a plurality of truncated-cone shaped protrusions extending laterally between the leg members.

Discharge lamp having envelope support spacer

A mount for an arc discharge lamp has a cathode thereon which is encircled by a disintegration shield. The shield has a narrow gap between its ends with a mercury-containing metal capsule in the gap. The capsule is comprised of a metal cup having a larger diameter portion and a smaller diameter portion, the larger diameter portion having been flattened and sealed after the mercury has been dispensed into the capsule. The flattened larger diameter portion of the capsule is welded across the gap of the shield.
