Abstract:
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.
