Description

Filter für Kraftfahrzeugscheinwerfer Die Erfindung bezieht sich auf ein Filter für Kraftfahrzeugscheinwerfer, insbesondere zur Verwendung bei nebeligem Wetter. Dasselbe besteht in einem klaren, durchsichtigen, ohne Zusatz trübender Mittel gefärbten Überzug aus Zaponlack, der vor der Lichtquelle des Schein-. Werfers, zweckmäßig auf der Außenfläche der Abschlußscheibe leicht aufzubringen und auch leicht wieder zu entfernen ist.Automotive Headlight Filters The invention relates to a filter for motor vehicle headlights, especially for use in foggy conditions Weather. The same thing consists of a clear, transparent one, without the addition of a clouding one Medium colored coating of zapon varnish, which is in front of the light source of the dummy. Thrower, convenient and easy to apply to the outer surface of the lens is easy to remove again.

Es ist zwar schon bekannt, Scheinwerferscheiben mit Anstrichmassen zu versehen. Es waren jedoch nur einfache gelbe Farbanstriche, die entweder nur durch chemische Mittel oder scharfes Abkratzen vom Glase wieder zu entfernen waren. Ein dabei empfohlenes Mittel, diesen Mangel durch nicht trocknende Zusätze zu beheben, führt jedoch zur Annahme von Staubteilchen und damit zur Trübung der Durchsicht.It is already known to use headlights with paints to provide. However, it was just plain yellow paintwork that was either only could be removed from the glass by chemical means or by sharp scraping. A recommended means of remedying this deficiency with non-drying additives, however, it leads to the acceptance of dust particles and thus to the clouding of the view.

Auch Celluloselacke sind für diesen Zweck bereits verwendet worden, sie waren aber stets mit die Durchsicht hindernden Farben mit Trübungsmitteln gefärbt; außerdem haftet ihnen der Mangel an, vom Glase abzublättern. Der farbige Zaponlacküberzug dagegen läßt sich in nassem Zustande von der Glasscheibe leicht ablösen, hält wider alles Erwarten beim Fahren in Wind und Wetter auf dem Glase der Abschlußscheibe sehr gut stand, ohne auch bei öfterem-Wechsel von Hitze und Kälte, Feuchtigkeitsniederschlägen, Nässe und Trockenheit von selbst abzuspringen. Im Vergleich zu anderen durchsichtigen Überzügen bietet der aus Zaponlack hergestellte an sich bekanntlich noch den Vorteil, im Lichte kein eigenes Farbenspiel hervorzurufen, so daß im wesentlichen nur die dem Lack gegebene Färbung wirksam wird, wodurch störende Lichtreflexe im Nebel weitgehendst vermieden werden.Cellulose lacquers have also been used for this purpose, but they were always tinted with opacifiers with colors that hinder the view; in addition, they have a lack of flaking off the glass. The colored zapon coating on the other hand, it can easily be removed from the pane of glass when it is wet, but withstands everything expected when driving in wind and weather on the lens of the lens stood very well without moisture deposits, even with frequent changes from heat and cold, To jump off wetness and dryness by itself. Compared to other see-through Coatings made from zapon lacquer still offer the advantage, as is well known, to produce no own play of colors in the light, so that essentially only the The color given to the paint becomes effective, which largely causes disruptive light reflections in the fog be avoided.
