Bei der Erfindung handelt es sich um die Ausbildung der Lichtfenster von Fahrzeufleuchten, vorzugsweise Heck·· leuchten. Aus Sicherheitsgründen versucht man, die zur Verfügung stehende Lichtfensterfläche solcher Leuchten so zu gestalten, daß sie möglichst unempfindlich gegen Verschmutzung ist. Um den Leucht-Wirkun^sgrad noch zu verbessern, ist bei einer bekannten Ausführung einer Heckleuchte die Oberfläche des Lichtfensters etwa Oarallel zur Fahrb-ahnebene trrofiliert, so daß die Lichtdurchtrittsflache entsprechend vergrößert ist.The invention concerns the training of the Light window of vehicle lights, preferably rear to shine. For safety reasons, attempts are made to reduce the available light window area of such luminaires in this way to design that it is as insensitive as possible to pollution. In order to increase the luminous efficiency improve, in a known version of a rear light, the surface of the light window is about Oarallel to the Fahrb-ahnebene trrofiliert so that the Light passage area is enlarged accordingly.
Diese bekannte Ausführunßrsform, bei welcher im Einbauzustand betrachtet, die Lichtfensterprofilierung streng rechteckförmig waagrecht verlaufend vorgesehen ist, weist den Nachteil auf, daß auf den Oberseiten beispielsweise Staubteile sich ablagern und den Lichtaustritt an diesen Flächen stark verhindern·· Außerdem ist der selbstreinigende Effekt bei Regrenfahrt, hervorgerufen durch den Regen selbst oder durch ablaufendes S^ritzwasser im Bereich der Leuchte, bei dieser Ausbildung schlecht, da die nach oben wendenden Profilflächen nraktisch keinen ^'pülfluß zulassen.This known embodiment, in which in the installed state considered, the light window profiling is provided to run horizontally in a strictly rectangular shape, has the disadvantage that, for example, dust particles are deposited on the upper sides and the light emerges from them Strongly prevent surfaces ·· In addition, the self-cleaning effect when driving is caused by the rain itself or by running water splash in the area of the luminaire, bad with this training, because the turn upwards Profile surfaces practically do not allow any flushing flow.
Um insbesondere bei Fahrzeug-Heckleuchten diese Nachteile zu vermeiden, wird nun erfindunpsgemä'ß vorgeschlagen, das Lichtfenster derart zu nrofilieren, daß der normale VerstaubunfTsnrozeß verlangsamt wird und bei Regenwetter ein guter Abwascheffekt erreicht wird.In order to address these disadvantages, particularly in the case of vehicle rear lights to avoid, it is now proposed according to the invention that To contour light windows in such a way that the normal process of dust accumulation is slowed down and in rainy weather a good wash-off effect is achieved.
Als Lösung der Aufsrnbe ist nun vorgesehen, das Lichtfenster derartiger Heckleuchten mit einem etwa quer zur Fahrbahnebene verlaufenden Profil zu versehen, so daß die Staub— The light window is now planned as a solution to the exterior to provide such rear lights with a profile running approximately transversely to the plane of the road, so that the dust-
