Description

Elektrischer Aäzeügscheinwerfer Das Hauptpatent betrifft einen elektrischen Fahrzeugscheinwerfer mit tiefem Ellipsoidspiegel und zwischen dessen beiden Brennpunkten angeordnetem, aus nebeneinanderliegenden Linsen bestehendem Linsensystem, das die ganze Lichtaustrittsöffnung ausfüllt. Das Wesentliche besteht hierbei darin, daß der eine Teil des Linsensystems sein konzentriertes Lichtbündel für Fernbeleuchtung und der andere Teil des Linsensystems ein streuendes Lichtbündel für Seitenbeleuchtung liefert.Electrical Aäzeügscheinwerfer The main patent relates to an electrical one Vehicle headlights with a deep ellipsoidal mirror and between its two focal points arranged lens system consisting of side-by-side lenses, which the fills the entire light exit opening. The essential thing here is that one part of the lens system is its concentrated light beam for long-distance lighting and the other part of the lens system a diffusing light beam for side lighting supplies.

Die vorliegende Erfindung betrifft eine weitere Ausgestaltung des Gegenstandes des Hauptpatents 645 294 insofern, als die Rückseite des einteilig ausgeführten Linsensystems eine nach unten derart zunehmende Kr ümmung nach dem Reflektorscheitel hin aufweist, daß die auftretenden Lichtstrahlen, von oben nach unten gerechnet, eine zunehmende Neigung zum Boden hin erhalten.The present invention relates to a further embodiment of the Subject of the main patent 645 294 insofar as the back of the one-piece executed lens system a downward such increasing curvature after Reflector apex shows that the light rays occurring, from top to bottom calculated at the bottom, an increasing incline towards the ground is obtained.

Die beiliegende Zeichnung zeigt schematisch einen Scheinwerfer nach der Erfindung im senkrechten Schnitt.The accompanying drawing shows schematically a headlight of the invention in vertical section.

Der Ellipsoidspiegel i, der im Brennpunkt die Lichtquelle 2 trägt, ist an seiner Lichtaustrittsöffnung mit einem Linsensystem 3, 4, 5 ausgefüllt, welches einerseits ein konzentriertes Lichtbündel für Fernbeleuchtung und anderseits ein streuendes Lichtbündel für Seitenbeleuchtung liefert. Auf der Innenseite weist das einstückig ausgeführte Linsensystem 3, 4, 5 eine nach unten derart zunehmende Krümmung 6 nach dem Reflektorscheitel hin auf; daß ein nach oben auftretender, punktiert gezeichneter Strahl a etwa in der Richtung des ausgezeichneten Strahles b abgelenkt wird.The ellipsoid mirror i, which carries the light source 2 at the focal point, is filled at its light exit opening with a lens system 3, 4, 5, which on the one hand a concentrated light beam for long-distance lighting and on the other hand provides a diffusing light beam for side lighting. On the inside it shows one-piece lens system 3, 4, 5 has a downwardly increasing curvature 6 towards the reflector apex; that an upward appearing, dotted Drawn ray a deflected approximately in the direction of the marked ray b will.

Die Krümmung 6 erstreckt sich von oben etwa bis zur Mittelachse des Linsensystems 3, 4, 5. Im unteren Bereiche ist die Krümmung 6' eine stärkere, um ein Bodenlicht, hervorgerufen durch die Strahlen c und d, zu erhalten. Im untersten Teil trägt die Krümmung 6' eine Absetzung 7, die nur die Aufgabe hat, die Wandstärke zu verringern.The curvature 6 extends from above approximately to the central axis of the Lens system 3, 4, 5. In the lower area, the curvature 6 'is stronger to obtain a ground light caused by rays c and d. In the lowest Part of the curvature 6 'carries a step 7, which only has the task of the wall thickness to reduce.
