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.
