Description
Glühlampe für Fahrzeugscheinwerfer. Die im folgenden dargelegte Erfindung stellt eine Verbesserung der im Hauptpatent Nr.146702 beschriebenen Glühlampe für Fahr zeugscheinwerfer dar.
Der Zweck dieser Erfindung sei anhand der Zeichnung, welche ein Ausführungsbei spiel des vorliegenden, in einen Reflektor montierten Erfindungsgegenstandes zeigt, fol gendermassen erläutert: Der im Innern des Glasballons einer Glüh lampe a angeordnete Glühkörper c, welcher zur Aussendung von farbigem, nicht blen dendem Licht bestimmt ist, wird von einer farbigen, transparenten, hitzebeständigen Hülle <I>d</I> teilweise umgeben. Diese Hülle<I>d</I> hat wenig stens angenähert die Form einer Halbkugel schale und ist derart angeordnet, dass die offene Seite dieser halbkugelschalenförmigen Hülle d mindestens angenähert die Axe der Lampe einschliesst.
Dadurch wird das vom Glühkörper c aus gehende Licht in zwei aneinandergrenzende Lichtkegel geteilt, wovon der eine, welcher auch den eingezeichneten Strahl f'-" enthält, das nicht blendende Licht enthält, während der andere, der den in der Zeichnung ange deuteten Strahl f 1 enthält, weisses, weit reichendes Licht aussendet.
Die Glühlampe a ist nun derart in den Sockel eines Fahrzeugscheinwerfers einzu setzen, dass das nicht blendende Licht durch den Reflektor e auf die Strassenseite ausge strahlt wird, auf welcher der Gegenverkehr stattfindet.
Bulb for vehicle headlights. The invention set out below is an improvement on the incandescent lamp described in the main patent No. 146702 for vehicle headlights.
The purpose of this invention will be explained with reference to the drawing, which shows a Ausführungsbei game of the present invention, mounted in a reflector, fol gendermassen: The inside of the balloon of an incandescent lamp a arranged incandescent body c, which to emit colored, non-dazzling light is partially surrounded by a colored, transparent, heat-resistant cover <I> d </I>. This shell <I> d </I> has at least approximately the shape of a hemispherical shell and is arranged such that the open side of this hemispherical shell-shaped shell d at least approximately includes the axis of the lamp.
As a result, the light emanating from the incandescent body c is divided into two adjacent light cones, one of which, which also contains the drawn beam f'- ", contains the non-dazzling light, while the other, the beam f 1 indicated in the drawing contains, emits white, far-reaching light.
The incandescent lamp a must now be placed in the base of a vehicle headlight in such a way that the non-dazzling light is emitted through the reflector e onto the side of the road on which the oncoming traffic takes place.
