Abstract

The headlamp (10) has a metal reflector (11) with an axial lip (15) around the central opening for receiving the bulb sealed to the mounting plate (16) for the latter. The bulb comprises a double filament halogen lamp (18) with a vacuum-sealed envelope (17) embedded in a socket (28) with the electrodes projecting from the envelope (17) projecting through respective sealed exit holes in the mounting plate (16). Pref. the lamp socket (28) is made of sheet metal and has an outer flange contacting the periphery of the mounting plate (16) and an inner conical flange contacting the outside of the lamp envelope. The mounting plate (16) is pref. also made of sheet metal and has a rolled edge welded to the reflector (11). PS.

Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem druckdichten Scheinwerfer für Kraftfahrzeuge nach der Gattung des Anspruchs 1. Es ist bereits aus der DE-OS 19 51 978 ein derartiger Scheinwerfer bekannt, dessen Scheitelbereich und die in diesem eingesetzte, handelsübliche Glühlampe druckdicht verschlossen werden. Dieser eine Übergangslösung darstellende druckdichte Verschluß erfordert zusätzliche Einzelmaßnahmen in der Herstellung des Scheinwerfers.The invention is based on a pressure-tight headlight for motor vehicles of the type Claim 1. It is already known from DE-OS 19 51 978 such a headlight, the apex area and the standard incandescent lamp used in this is sealed pressure-tight. This one Pressure-tight closure, which is a temporary solution, requires additional individual measures in production of the headlight.
