   Das letzte Beispiel (Fig. 6 und 6) zeigt einen Scheinwerfer, bei dem eine als Lichtquelle dienende Glühlampe e nach der von einer Glasscheibe   d   abgeschlossenen Lichtaustrittsöffnung des Gehäuses a wiederum durch einen   Hilfsspiegel f abgeschirmt   ist, der einen nach der   Austrittsöffnung   gerichteten Strahlenkegel dem im Gehäuse a befestigten Hohlspiegel c zuwirft. Bei diesem Scheinwerfer ist nur die der Glühlampe e zugewendete Flächef1desHilfsspiegelsfhöckerig. 



      P ATENT. ANSPRÜCHE   :   L   Scheinwerfer mit einem optischen System, um eine Lichtquelle an dem zu beleuchtenden Ort abzubilden, dadurch gekennzeichnet, dass in dem Gang mindestens eines Teiles der aus dem Scheinwerfer austretenden Strahlen eine durchsichtige Glasscheibe mit einer unregelmässige Höcker enthaltenden Oberfläche geschaltet ist, so dass von den diese Fläche durchdringenden Strahlen eine Vielzahl von Bildern der Lichtquelle entworfen wird, die, unregelmässig rings um die Achse des Strahlenkegels verteilt, einander überlagern.

   The last example (Fig. 6 and 6) shows a headlight in which an incandescent lamp e, which is used as a light source, is again shielded by an auxiliary mirror f after the light exit opening of the housing a, which is closed by a pane of glass d, which has a beam cone directed towards the exit opening to the im Housing a attached concave mirror c throws. In the case of this headlight, only the surface f1 of the auxiliary mirror facing the bulb e is bumpy.



      P ATENT. CLAIMS: L Headlight with an optical system to image a light source at the place to be illuminated, characterized in that in the corridor of at least part of the rays emerging from the headlight a transparent glass pane with a surface containing irregular bumps is connected, so that from For the rays penetrating this surface, a multitude of images of the light source is designed, which, irregularly distributed around the axis of the cone of rays, superimpose one another.

Claims (1)

2. Scheinwerfer nach Anspruch l, bei dem die höckerige Oberfläche von einer Ab- schlussscheibe dargeboten wird, dadurch gekennzeichnet, dass die aussenliegende Fläche dieser Scheibe oben ist. 2. Headlight according to claim 1, in which the humped surface is presented by a cover disk, characterized in that the outer surface of this disk is at the top. 3. Scheinwerfer nach Anspruch l, bei dem das optische System einen Glasspiegel enthält, dessen von der Lichtquelle abgekehrte Fläche versilbert ist, dadurch gekennzeichnet, dass seine andere Fläche die höckerige Oberfläche darbietet. 3. Headlight according to claim l, wherein the optical system contains a glass mirror whose surface facing away from the light source is silver-plated, characterized in that its other surface presents the humped surface.
