Description

Im Patent 928 032 ist ein Kraftfahrzeugscheinwerfer beschrieben, dessen Reflektor in zwei in Längsrichtung gegeneinander versetzte Halbreflektoren aufgeteilt ist und zwei im Brennpunkt jedes Halbreflektors angeordnete Glühlampen mit je einem Gegenreflektor aufweist.Patent 928 032 describes a motor vehicle headlight, the reflector of which is divided into two half-reflectors offset from one another in the longitudinal direction and has two incandescent lamps, each with a counter-reflector, arranged at the focal point of each half-reflector.

Die Erfindung befaßt sich mit der Anordnung der beiden Glühlampen innerhalb des Reflektors und schlägt eine besonders :günstige Ausführungsmöglichkeit vor, die darin besteht, beide Glühlampen mit ihren Gegenreflektoren in einem Tubus unterzubringen und diesen herausziehbar im Scheitelpunkt des Reflektors zu lagern. Innerhalb des Tubus kann man dann eine Trennwand vorsehen, die einerseits die beiden Lichtquellen gegeneinander abschirmt und andererseits - S-förmi.g gebogen - zugleich die Gegenreflektoren bildet. Durch diese Ausbildung ist eine einfache Auswechslung der Glühlampen ermöglicht und -die Anordnung der Gegenreflektoren erleichtert. Der Tubus kann entweder nach der Rückseite des Reflektors hin oder aber, und zwar in erster Linie bei solchen Scheinwerfern, die von der Rückseite her nicht zugänglich sind, durch die Abdeckscheibe, die zu diesem Zweck dann eine beispielsweise durch einen Deckel verschließbare Öffnung aufweist, herausgezogen werden. Er kann entweder Lichtdurchtrittsöffnungen aufweisen oder aus durchsichtigem Werkstoff bestehen.The invention is concerned with the arrangement of the two incandescent lamps inside the reflector and suggests a particularly: cheap design option before, which consists in placing both light bulbs with their counter reflectors in one tube to accommodate and to store this pull-out in the apex of the reflector. A partition wall can then be provided within the tube, which on the one hand the two Shields light sources from each other and on the other hand - S-shaped curved - at the same time which forms counter reflectors. This training makes replacement easy of the incandescent lamps and facilitates the arrangement of the counter reflectors. Of the The tube can either go to the rear of the reflector or, to be precise, in primarily with headlights that are not accessible from the rear are, through the cover plate, which for this purpose then, for example, through has a lid closable opening, are pulled out. He can either Have light passage openings or consist of transparent material.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung, und zwar stellt Abb. i einen Längsschnitt durch einen Scheinwerfer dar, während Abb. 2 eine Einzelheit zeigt.The drawing illustrates an embodiment of the invention, namely Fig. i represents a longitudinal section through a headlight, while Fig. 2 shows a detail.

Der aus den gegeneinander versetzten Halbreflektoren i und 2 bestehende Scheinwerferreflektor ist durch die Abdeckscheibe 3 verschlossen. Im Scheitelpunkt des Reflektors befindet sich der Tubus q., der .die Glühlampen 5 und 6 aufnimmt. Die Gegenreflektoren für die beiden Glühlampen werden gebildet durch die Trennwand 7, die entsprechende Auswölbungen 8 und g aufweist. Diese Trennwand trägt zugleich die Fassungen io und ii für die Glühlampen und ist tierausziehbar im Scheitelpunkt des Reflektors gelagert. Im'Tubus q. sind Lichtaustrittsöffnungen 12 und 13 vorgesehen, die aus etwa halbkreisförmigen Ausnehmungen aus dem Tubus bestehen, wie in Abb. 2 näher dargestellt. Der freie in den Reflektorraum hineinragende Teil des Tubus kann gegebenenfalls zur Aufnahme der Standlichtlampe 14 oder anderer für den Betrieb des Kraftfahrzeugs benötigte Signalgeräte dienen.The one consisting of the offset half-reflectors i and 2 The headlight reflector is closed by the cover plate 3. In the vertex of the reflector is the tube q., which takes the light bulbs 5 and 6. The counter reflectors for the two bulbs are formed by the partition 7, which has corresponding bulges 8 and g. This partition wall carries at the same time the sockets io and ii for the light bulbs and can be pulled out at the apex of the reflector stored. In the 'tube q. light exit openings 12 and 13 are provided, which consist of approximately semicircular recesses from the tube, as shown in Fig. 2 shown in more detail. The free part of the tube protruding into the reflector space can optionally to accommodate the parking light lamp 14 or other for operation the motor vehicle required signal devices are used.
