Beschreibung zur Gebrauchsmusteranmeldung: "Zur Abgabe'farbigen Lichts bestimmte Scheinwerfer und Leuchten für Zwecke des Yerkehrs, deren lichtquelle mit einem Eeflektor hinterlegt ist."Description of the utility model registration: " Headlights and lights intended for outputting colored light for purposes of traffic, the light source of which is backed by an eeflector."
Im Terkehrswesen Terwendet man für bestimmte Zwecke Scheinwerfer und leuchten mit farbigem licht* Sie dienen z.B. zur Signalgabe oder zur Erzielung einer besseren Sieht bei Nebel und dunstigem .-Wetter oder zur Abschwächung der Direktblendung. Die Einfärbung der von der lichtquelle ausgehenden weißen liehtstrahlen erfolgt vornehmlich durch eine in der gewünschten iarbe eingefärbte Abdeckscheibe oder durch Aufbringen einer farbschicht auf den Glühlampenkolben oder durch vorgesetzte farbige Filter. Bei -Eraftfahrzeug-Feb el Scheinwerfern ist z.B» die Abdeckscheibe üblicherweise gelblich gefärbt, während die Signalleuchten an Kraftfahrzeugen fenster in Signalfarbe- aufweisen» Die bisher angewandten Mittel zur Erzeugung der farbigen Lichtstrahlen haben den Sacht eil gemeinsam, daß ein erheblicher Seil der auf gewandten lieht energie absorbiert wird. In traffic, headlights are used for certain purposes and shine with colored light. The white rays emanating from the light source are colored primarily by means of a cover disc colored in the desired color or by applying a layer of color to the light bulb or by means of a colored filter placed in front of it. In -Eraftfahrzeug-Feb el headlights, for example, »the cover panel is usually yellowish in color, while the signal lights on motor vehicles have a signal color-» The previously used means for generating the colored light rays have one thing in common that a considerable amount of rope lends the agile energy is absorbed.
Die Heuerung betrifft Scheinwerfer und leuchten* die zur Abgabe farbiger Iiehtstrahlen bestimmt sind und deren Lichtquelle mit einem Reflektor hinterlegt ist und schlägt zwecks Behebung des aufgezeigten mangels Tor, den !Reflektor mit einer selektiv wirkenden Spiegelschicht zu τersehen, wobei der Austritt ungefärbter Iiehtstrahlen durch bekannte Kittel z. B. durch eine τorThe hiring concerns headlights and shine * those for delivery colored light rays are determined and their light source with is deposited in a reflector and suggests to remedy the indicated for lack of goal, the! reflector with a selective acting mirror layer to see, whereby the exit uncolored Iichtstrahl through well-known smock z. B. by a τor

A selectively acting Eeflektorspiegel can be z * B. represent by vapor deposition of a high-gloss copper or gold foil ent on the mirror support *
Die Wirkung eines solchen Befielt ore kann durch Aufbringen τοη Interferenzschichten auf den selektiv wirkenden Spiegel verstärkt werden* Die Interferenzschiehten können in an sich bekannter Weise z.B. aus Sulfiden, Fluoriden, Oxyden und/oder halbdurchlässigen Spiegelschichten bestehen. Die Anordnung des -neusstangegemäßen Ueflektorspiegels hat den Vorteil einer besseren lichtausbeute. Ferner kann eine klarje Abdeckeeheibe verwendet werden. Es ist an anderer Stelle bereits vorgeschlagen worden, zur Yermeidung der Blendgefahr beim nächtlichen Straßenverkehr das licht der Kraftfahrzeughauptscheinwerfer derart zu polarisieren, daß die Strahlen mittels eines Analj^sators gelöscht werden können. Die Schwingungsrichtung des Analysators ist so orientiert, daß zwar das polarisierte Licht des eigenen Fahrzeugs sichtbar bleibt, das des entgegenkommenden Fahrzeuges ;jedoch im wesentlichen ausgelöscht wird.The effect of such an inflicted ore can be achieved by applying τοη Interference layers are reinforced on the selectively acting mirror * The interference layers can be used in a manner known per se e.g. consist of sulfides, fluorides, oxides and / or semi-permeable mirror layers. The arrangement of the -neussangeges Ueflektorspiegel has the advantage of a better light yield. Furthermore, a Klarje cover disc can be used. It has already been suggested elsewhere, for avoidance the risk of dazzling in traffic at night to polarize the light of the vehicle's main headlights in such a way that that the rays can be extinguished by means of an analyzer. The direction of vibration of the analyzer is oriented so that although the polarized light of your own vehicle remains visible, that of the oncoming vehicle; but essentially is extinguished.
Es hat sich nun herausgestellt, daß eingestrahltes polarisiertes licht an Hebeltröpfchen vorwiegend im gleichen Sinne polarisiert zurückgespiegelt wird. Man kann daher mittels eines entsprechend orientierten Analysators diesen Spiegelreflex auslöschen· Es wird aus dieser Erkenntnis heraus weiterhin vorgeschlagen,zur Erhöhung der Sichtverbesserung neuerungsgemäß ausgebildete Nebelscheinwerfer zusätzlich mit einem Polarisationsfilter auszustatten, dessen Selektion etwa auf .den selektiv wirkendenIt has now been found that the irradiated polarized light on lever droplets polarized predominantly in the same sense is reflected back. This mirror reflex can therefore be extinguished by means of an appropriately oriented analyzer On the basis of this knowledge, it is further proposed that newly designed ones be designed to increase the improvement in vision To equip fog lights additionally with a polarization filter, the selection of which is based on the selectively acting
