Abstract
An electric lamp includes a hybrid skirted lamp base including a plastic skirt portion and a metallic skirt portion having one end portion molded in said plastic skirt portion and a second end portion secured to the lamp envelope. The metallic skirt portion improves structural integrity and provides some thermal isolation from the lamp envelope allowing the use of a lower temperature plastic for the plastic skirt portion. The plastic skirt portion includes a weldless and solderless lamp base. A lamp cap contact includes a rigid shank received in a clamping bore of the plastic skirt portion. The diameters of the bore and shank and the elasticity of the bore wall are selected so that a conductive lead of the lamp is securely clamped between the shank and the bore wall when the shank is fully received in the bore. In a favorable embodiment, the lead has a free end extending in the direction of insertion of the shank into the bore, which avoids the lead wire from being pushed out of the bore.
