Beschreibung zur Gebrauehsmüsteranmeldungj "Kraftfahrzeugs eheinwerf er mit polarisiertem Lieht.«Description of the master craftsman registration j "He throws in a motor vehicle with polarized light."
.Zur Terminderung der Blendgefahr im nächtlichen Strasseeverkehr verwendet man .Kraftfahrzeugscheinwerfer, die polarisiertes Licht aussenden, deren Strahl en durch einen Analysator ausgelöscht werden iönnen. Die Polarisation des aus der Glühlampe des Scheinwerfers austretenden Lichtes erfolgt durch Pilter, Torzugsweise organischen'Ursprungs, die nur Lichtstrahlen in einer Sichtung durchlassen* .Zur Vermeidung von Beschädigungen des empfindlichen Puters wird dieses zwischen zwei Glasscheiben angeordnet, von denen die äussere stärkere Seheibe mechanische Beschädigungen verhindern soll, während die zweite dünnere Scheibe das PiIter in seiner Lage JaäTt". Das von einem solchen Seheinwerfer ausgehende Lieht muß eine gewisse Streuung besitzen, um die gesamte Straßenbreite ausleuchten zu können. Es liegt an sich nahe, die vordere stärkere Schutzscheibe des ELl-fcers als Streuscheibe auszubilden. Es hat sieh jedoch dabei herausgestellt, daß die in einer Streuseheibe vorhandenen inneren Spannungen, die durch d en Preßvorgang hervorgerufen werden, einen 2?eil des hindurehtr et enden polarisierten Lichtes wieder depolarisieren.To reduce the risk of dazzling in road traffic at night One uses. Motor vehicle headlights, the polarized light emit, the rays of which can be extinguished by an analyzer. The polarization of the headlamp's light bulb Exiting light is done by pilter, Torweise organic 'origin that only rays of light in one sighting let through * .To avoid damaging the sensitive This is placed between two panes of glass by Puter which the outer, stronger glass pane prevents mechanical damage should, while the second thinner slice is the PiIter in Its location JaäTt ". That emanating from such a spotlight Lieht must have a certain spread in order to be able to illuminate the entire width of the street. It is obvious in itself, the front one to design a stronger protective disc of the ELI-fcer as a diffuser. However, it turned out to be in a litter tray existing internal stresses caused by the pressing process caused a 2? part of the hindurehtr et ends polarized Depolarize light again.
Die !Teuerung schlägt gegenüber dieser vorbeschriebenen .Anordnung vor, die Streuseheibe zwischen dem Pilter und der Glühlampe anzuordnen dergestalt, daß die bereits gebündelten Lichtstrahlen durch das ELlter fallen und dort polarisiert werden. Diese Anordnung - :_ : : Blatt 2The price increase suggests compared to this above .Anordnung to arrange the diffuser between the pilter and the incandescent lamp in such a way that the already bundled light rays fall through the ELlter and are polarized there. This arrangement -: _: Part 2
hat den weiteren Vorteil, die τοη der Glühlampe abgegebene Wärme von dem Filter fernzuhalten. Gemäß einer weiteren Ausführung des Neuerungsgedankens kann auch die Streuscheibe unmittelbar mit dem Reflektor verbunden werden, eodaß die sich entwickelnde Wärme völlig innerhalb des geschlossenen Reflektors verbleibt. Ein weiterer Vorteil bei 4er Anordnung der Streuscheibe zwischen Polarisator und Lichtquelle ergibt sich daraus, daß man keim Heigen des Reflektors zum Zwecke der Abblendung, die aus dem Reflektor austretenden Lichtstrahlen vor ihrer Polarisation in dem jeweiligen Verwendungszweck angepasster Weise bündeln kann· Die Bündelung natürlichen Lichtes lässt sich besser durchführen als die Bündelung bereits polarisierten Lichtes, da man in diesem Falle nicht mit etwaigen Depolarisationserscheinungen zu rechnen hat. Diesen Vorteil hat man sowohl bei einer neigung des Reflektors gegenüber einer feststehenden als auch bei einer mit dem Reflektor festverbundenen Streuscheibe.has the further advantage that the heat given off by the incandescent lamp away from the filter. According to a further embodiment of the concept of innovation, the lens can also be used directly be connected to the reflector, so that the developing heat remains completely within the closed reflector. Another advantage of arranging the lens between four The polarizer and the light source result from the fact that one germs Heigen of the reflector for the purpose of dimming, the light rays emerging from the reflector before their polarization in the respective Can bundle the intended use in an adapted manner · The bundling of natural light can be carried out better than the bundling of already polarized light, since in this case one does not have to reckon with any depolarization phenomena. You have this advantage both with an inclination of the reflector in relation to a stationary one as well as in the case of one with the reflector firmly connected lens.

Die Polarisationseinrichtung besteht aus der äusseren Schutzscheibe 1, dem Polarisationsfilter 2 und der Deckseheibe 3· Zwischen dieser Einrichtung und der im Brennpunkt des Reflektors angeordneten Lichtquelle 6 ist die Streuscheibe 4 angeordnet· Durch die Verstellvorrichtung 7 lässt sich der Reflektor gegenüber der Polarisationseinrichtung neigen.The polarization device consists of the outer protective screen 1, the polarization filter 2 and the cover pane 3 The diffusing screen 4 is arranged between this device and the light source 6 arranged at the focal point of the reflector. The reflector can be inclined with respect to the polarization device by means of the adjustment device 7.
