Electric lamp structure

Claim 1

A lamp structure comprising a sealed enclosure containing a source of radiant energy, an annular resilient electrically conductive base member, said base member having a peripheral configuration which is substantially symmetrical with respect to its central vertical axis, said base member is resilient in a radial direction, at least one series of circumferentially spaced openings in said base member, a first electrical circuit connecting said radiant energy source with said base member, a second electrical circuit connecting said radiant energy source with a lower lamp contact element, said base member and said lower lamp contact element separated by a lower electrical insulator element, said annular base member having an upper annular edge and a lower annular edge, at least one of said annular edges secured to a portion of said lamp adjacent the lower portion of said sealed enclosure, whereby axial insertion of the base of said lamp structure into a nonyielding electrical socket results in said base member being substantially uniformly circumferentially radially inwardly resiliently deformed, said lamp is an incandescent lamp, said sealed enclosure is, at least in part, composed of a vitreous material, said base member has a generally C-shaped elevational crosssectional configuration, said base member has a substantially circular cross-sectional configuration in a plane which is perpendicular to its central axis, said circumferentially spaced openings include a plurality of elongated openings oriented substantially parallel to the central axis of said base member, and said elongated openings originate at a position spaced below said upper annular edge and terminate at a position spaced above said lower annular edge.
