Electric lamp with cementless attached base

摘要

To permit insertion of a halogen cycle lamp into a standard bayonet or screw-in socket, the glass press stem of the lamp is connected to a standard base by a resilient spring disk formed with a circumferentially notched or serrated edge fitting into the lamp base, the spring disk being formed with a central opening into which the lamp press stem fits, the press stem having wedge-shaped projections thereon which engage behind tabs projecting from the spring disk. Additional projections may be formed on the lamp for engagement with further tabs on the disk for proper centering of the bulb.
