Description
Scheinwerfer für Kraftfahrzeuge Gegenstand der Hauptpatentanmeldung M 31670 II/63 c ist ein Scheinwerfer für Kraftfahrzeuge, dessen Reflektor aus durch lotrechte Schnitte abgeteilten Teilen besteht, von denen jedes um eine lotrechte Achse geschwenkt werden kann. Wenn alle Teile des Reflektors nach rechts geschwenkt sind, ist eine linksseitige Abblendung vorhanden. Dabei zeigt sich als Nachteil, daß die linke Straßenhälfte unbeleuchtet bleibt. Es wäre von Vorteil, wenn es sich so einrichten ließe, daß bei einer derartigen Einstellung die linke Straßendecke beleuchtet bliebe.Headlights for motor vehicles Subject of the main patent application M 31670 II / 63 c is a headlight for motor vehicles, whose reflector is made by there are perpendicular sections of divided parts, each of which is a perpendicular Axis can be swiveled. When all parts of the reflector are swiveled to the right there is a fade-out on the left. The disadvantage here is that the left half of the street remains unlit. It would be beneficial if it were let set up so that with such an adjustment the left surface of the street would remain illuminated.
Dies läßt sich dadurch erreichen, daß der Reflektor nicht ganz geteilt wird, sondern daß nur die untere Hälfte oder die unteren zwei Drittel aus durch lotrechte Schnitte abgeteilten Teilen bestehen, von denen jedes um eine lotrechte Achse geschwenkt wird. Der obere Teil bleibt ganz und feststehend, da dieser ja hauptsächlich zum Bestrahlen der Straßendecke dient. Er kann um eine waagerechte Achse drehbar oder zurücksetzbar angebracht sein, um die Länge der Beleuchtung der Straßendecke regeln zu können.This can be achieved in that the reflector is not completely divided but that only the bottom half or the bottom two thirds from through There are perpendicular cuts divided parts, each of which is a perpendicular Axis is swiveled. The upper part remains whole and fixed, because this one yes mainly used to irradiate the road surface. He can move a horizontal one The axis can be rotated or reset to match the length of the lighting To be able to regulate the road surface.
Die Maßnahmen, den Reflektor eines Kraftfahrzeuges waagerecht zu teilen und den oberen Reflektorteil um eine waagerechte Achse zu schwenken oder den oberen Teil zwecks Ahlenkens der Strahlen zurücksetzbar anzubringen, sind an sich bekannt.The measures to divide the reflector of a motor vehicle horizontally and to pivot the upper reflector part about a horizontal axis or the upper one Part for the purpose of Ahlenkens the rays to be resettable are known per se.
Es ist nunmehr möglich, auch bei Vorsatz von Streuscheiben nur den Lichtkegel oberhalb der Straßendecke nach links oder rechts zu schwenken; dabei kann sowohl der gesamte Lichtkegel oberhalb der Straßendecke geschwenkt werden, wenn alle Teile des unteren Reflektors geschwenkt werden; es kann aber auch nur ein Teil des Lichtkegels oberhalb der Straßendecke abgelenkt werden, indem nicht alle unteren Reflektorteile geschwenkt werden.It is now possible to swivel only the cone of light above the road surface to the left or right, even when using lenses; the entire light cone can be swiveled above the road surface if all parts of the lower reflector are swiveled; however, only part of the light cone above the road surface can be deflected by not pivoting all of the lower reflector parts.
Mit Hilfe dieser Einstellmöglichkeiten und unter Verwendung der bekannten Zweifadenglühbirne ist der Fahrer in der Lage, folgende Beleuchtungen vorzunehmen 1. Vollbeleuchtung wie bisher, 2. Abblenden wie bisher, notwendig bei Stadtfahrt, wobei nur die Straßendecke beleuchtet wird, und 3. Vollbeleuchtung mit nach links oder rechts gerichtetem Lichtkegel oberhalb der Straßendecke.With the help of these setting options and using the known Two-filament lightbulb, the driver is able to provide the following lighting 1. Full lighting as before, 2. Dimming as before, necessary when driving around town, whereby only the road surface is illuminated, and 3. full illumination with to the left or right-directed light cone above the road surface.
