摘要： Die Halogenglühlampen-Reflektor-Einheit weist eine Zentrierscheibe (10b) auf, dessen äußerer Rand auf der Innenseite des Reflektors (6) und dessen zentrale Öffnung auf dem Übergang von der Quetschung (3) zum Kolben der Halogenglühlampe (1) aufliegt. Die Zentrierscheibe (10b) ist eben oder mit einer angeprägten Stufe versehen. Mit Hilfe der Zentrierscheibe (10b) kann das Auflagemaß, d.h. der Abstand Wendel-Scheitelpunkt Reflektor verändert werden, um Fertigungstoleranzen auszugleichen oder um mit nur einem Reflektortyp unterschiedliche Lichtkegel (flood, spot) zu erzeugen.

摘要： A replaceable automobile headlight lamp unit and headlight utilizing same wherein the unit's electric lamp (e.g., tungsten halogen) is securedly retained within a clamp member including an insulative base and a pair of spaced-apart retaining clips for grasping the lamp's press-sealed end portion. The base includes a curvilinear surface which mates with a surface having a similar configuration located within an insulative holder which also forms part of the invention. A pair of spaced contacts located within the holder pass through apertures within the base and are connected (e.g., welded) to the retention clips. A ball-joint arrangement is thus provided to enable facile alignment of the electric lamp relative to the holder prior to final securement between the holder and base components.

摘要： A molded glass reflector member for a lamp unit employing a tungsten halogen lamp as the light source is disclosed having a recessed opening at its base end and which further provides an engagement surface for mounting said lamp unit. Specifically, said improved lamp unit includes a molded glass reflector member terminating at its base end in an elongated hollow cavity protruding from the rear side of said reflector member, said cavity having a recessed opening of smaller size at the rearmost end which also provides a recessed engagement surface for mounting said lamp, and a tungsten halogen lamp secured in said hollow cavity so that its light source is positioned at the focal point of said reflector member and the lamp inleads project through said recessed opening. In a preferred embodiment, said recessed opening is formed by spaced apart shoulders extending from the inner walls of the protruding hollow cavity.
