Description

Scheinwerfer Bei Kraftfahrzeugen macht sich die Blendwirkung der Scheinwerfer äußerst nachteilig bemerkbar. Es sind zwar bereits Scheinwerfer bekannt, bei denen der Reflektor, wie bei dem angemeldeten Patent, aus einem Ringspiegel und einem schwenkbaren Schalenspiegel besteht. Sie sind aber größtenteils unzulänglich, da sie besonders auf verkehrsreichen Landstraßen ein fast ununterbrochenes Abstoppen der Fahrgeschwindigkeit bedingen.Headlights In motor vehicles, the dazzling effect of the headlights increases extremely disadvantageous noticeable. There are already known headlights where the reflector, as in the patent pending, consists of a ring mirror and a swiveling shell mirror consists. But they are mostly inadequate there they stop almost continuously, especially on busy country roads the driving speed.

Nach der Erfindung werden die Nachteile solcher Scheinwerfer vollkommen beseitigt, und zwar dadurch, daß die Drehachse des Schalenspiegels durch den für Ring- und Schalenspiegel gemeinsamen Brennpunkt, in welchem die Lichtquelle angeordnet ist, hindurchgeht. Der Scheinwerfer bleibt trotz der Abblendung in voller Wirkung in bezug auf Reichweite und Lichtstärke.According to the invention, the disadvantages of such headlights are eliminated eliminated, namely that the axis of rotation of the pan mirror by the for Ring and bowl mirrors have a common focal point in which the light source is arranged is going through. The headlight remains fully effective despite the dimming in terms of range and light intensity.

Der in der Zeichnung beispielsweise als Kraftwagenscheinwerfer dargestellte Erfindungsgegenstand ist ein Scheinwerfer a, dessen Reflektor aus einem feststehenden Ringspiegel b und einem diesen zu einem vollen Paraboloid ergänzenden schwenkbaren Schalenspiegel c besteht, dessen Drehachse durch den gemeinsamen Brennpunkt, in welchem die Lichtquelle e angeordnet ist, hindurchgelegt ist.The one shown in the drawing, for example, as a motor vehicle headlight The subject of the invention is a headlight a, whose reflector consists of a fixed Ring mirror b and a pivotable one that supplements it to form a full paraboloid Shell mirror c, whose axis of rotation passes through the common focal point, in which the light source e is arranged, is passed through.

Die beiden Reflektorenteile b und c sind durch Scharniere f und g od. dgl. beiderseits so verbunden, daß die Drehpunkte des Schalenspiegels und der Lichtquelle in die Schwenkachse 1-I fallen. Dadurch wird erreicht, daß der Brennpunkt der Lichtquelle auch bei mitschwenkender Lampe in seiner Lage zum Ringspiegelreflektor b unverändert bleibt. Durch Verschwenkung des Schalenspiegels c wird der blendende Strahlenkern der Blendwirkung benommen, die Reichweite und Lichtstärke des Ringspiegelreflektors b bleibt hingegen unbeeinflußt. Die Abblendung des Scheinwerfers kann daher bei Sichtbarwerden entgegenkommender Fahrzeuge ohne Verminderung der Eigengeschwindigkeit vorgenommen werden. Die als Lichtquelle verwendete Lampe kann sowohl im Ringspiegel b feststehend als auch im Schalenspiegel c mitschwenkbar angeordnet werden.The two reflector parts b and c are secured by hinges f and g Od. Like. Connected on both sides so that the pivot points of the pan mirror and the Light source fall into pivot axis 1-I. This ensures that the focal point of the light source in its position in relation to the ring mirror reflector even when the lamp is pivoting b remains unchanged. By pivoting the shell mirror c, the dazzling Radiation core of the dazzling effect, the range and light intensity of the ring mirror reflector b, however, remains unaffected. The headlight can therefore be dimmed at Oncoming vehicles become visible without reducing their own speed be made. The lamp used as a light source can be used both in the ring mirror b can be arranged so as to be stationary and also pivotable in the shell mirror c.

Die Betätigung der Schwenkeinrichtung des Schalenspiegels c kann beispielsweise mittels Seilzug i und Rückholfeder h oder durch elektromagnetische Einrichtungen u. dgl. erfolgen.The pivoting device of the pan mirror c can be actuated, for example, by means of a cable pull i and a return spring h or by electromagnetic devices and the like.
