Patent ID: 7990036

Claim:
An electric lamp comprising: a tubular glass discharge vessel having a longitudinal axis, an axial plane P and opposite end portions each having a pinched seal, each pinched seal having two opposed major side faces along plane P and two opposed narrow side faces, wherein the end portions of the tubular glass discharge vessel each comprise an open cylindrical extremity for bringing about an elevation with respect to corresponding major side faces of an adjacent pinched seal; electrodes disposed inside the discharge vessel proximate opposite end portions of the tubular glass discharge vessel; current conductors connected to a respective electrode, emanating from the discharge vessel through a respective pinched seal proximate opposite end portions of the tubular glass discharge vessel; an ionizable gas filling in the discharge vessel; and metal mounting members present radially mounted on each of the pinched seals, via approaching a respective pinched seal radially instead of axially, to facilitate introduction of the discharge vessel in into and removal from a tubular glass sleeve, wherein the pinched seals are H-shaped in sections cross to the axis, a pair of the mounting members is presen being radially mounted on each seal, each mounting member of the pair of the mounting members (i) seizing about a narrow side face and engaging the major side faces with a non-welded clamping fit and (ii) having axially extending support portions at either side of plane P, wherein the axially extending support portions are situated at a distance from the respective major side face to serve as gliders to facilitate introduction of the discharge vessel into and removal from a sleeve, further wherein the pinched seals each have transversely extending profiles, the transversely extending profiles further including (i) recesses in the narrow side faces or the major side faces of respective pinched seals or (ii) one or more bosses on the major side faces of respective pinched seals, and wherein the respective mounting members cooperate with the recesses or one or more bosses of the transversely extending profile of the respective pinched seal to counteract axial displacement between a respective corresponding pinched seal and mounting member, wherein each mounting member keeps an axially directed metal tongue positioned, which extends to beyond the adjacent end portion of the discharge vessel and has a radially hooked end.
