Description
Verfahren zum Vermeiden des Uberdeckens oder Vortäuschens von Lichtsignalen durch Fremdlicht, insbesondere bei Fahrzeugleuchten Signale aller Art, insbesondere das Abwinken, werden von Fremdlicht oft überdeckt oder vorgetäuscht. Für Blinkleuchten wurde daher vorgeschlagen, Gehäuseteile, die nicht dem Lichtaustritt dienen, in der Komplementärfarbe zu halten.Method for avoiding covering up or faking light signals by extraneous light, in particular in the case of vehicle lights, signals of all kinds, in particular the waving, are often covered or simulated by external light. For flashing lights it was therefore proposed that housing parts that are not used for light exit in to keep the complementary color.
Demgegenüber werden nach der Erfindung die Außenfläche des Farbfilters oder andere Flächenteile, durch die das Licht austritt, mit einer durchlässigen Schicht in abweichender, vorzugsweise gegensätzlicher Farbe versehen. Statt dessen kann die Filterschicht selbst aus einem Werkstoff bestehen, der in auf- und durchfallendem Licht verschiedenfarbig erscheint. Bei weißen Signalen wählt man etwa Blau als Kontrastfarbe. Ist das Filter beispielsweise mit einer dünnen Lackschicht in der Komplementärfarbe überspritzt, so kann Fremdlicht kein falsches Signal erregen. Dagegen entsteht beim Ein- und Ausschalten ein zeitlicher Farbkontrast, der das Signal aufdringlicher macht.In contrast, according to the invention, the outer surface of the color filter or other parts of the surface through which the light emerges with a permeable Layer provided in a different, preferably a contrasting color. Instead of this the filter layer itself can consist of a material that falls in both the striking and falling Light appears differently colored. In the case of white signals, for example, blue is chosen as the contrasting color. For example, if the filter has a thin layer of lacquer in the complementary color overspray, extraneous light cannot generate a false signal. On the other hand arises with Switching on and off a temporal color contrast that makes the signal more intrusive power.
