A replaceable lamp assembly for automotive headlamps includes an incandescent lamp having a pinch seal mounted on a plastic base by means of a one piece sheet metal holder. One end of the holder clamps around the pinch seal of the lamp and the other end is secured to the plastic base via a pair of leg portions each having a spherical gimballed end RF welded to the base.

Replaceable lamp assembly for automotive headlamps

A circular fluorescent lamp unit having a central screw-in hub containing lamp ballast means, and a plurality of support arms extending from the hub and having curved outer ends to support a circular lamp. The support arms are metal or plastic strips which enter through slots of the hub and are bent at substantially right angles within the hub so as to be held in place while having limited radial movement with respect to the hub to enable them to accommodate and support circular lamp bulbs of varying dimensions such as due to manufacturing tolerance variations.

Improved positioning means are provided to locate a light source at the focus of a parabolic aluminized reflector (PAR) lamp and, in particular to improved positioning means which center said light source in the plastic reflector of a PAR lamp and preferably an all plastic PAR lamp. The preferred mount construction being employed utilizes a plastic block having mating parts which define a cavity from which lead wires extend and which is filled with an elastomeric polymer providing both a leak-proof seal around the lead wires as well as a more reliable barrier to moisture leakage through the mount assembly. The improved positioning means can be rib elements located in the receptacle means on said reflector to which said plastic mount is joined.
