Description

"Verfahren zur blendfreien Gestaltung des Scheinwerferlichtes im Kraftfahrzeugverkehr." Das Verfahren betrifft die blendfreie Gestaltung des Scheinwerferlichtes im Kraftfahrzeugverkehr durch Polarisationsfilter."Process for the glare-free design of headlights in motor vehicle traffic." That The method relates to the glare-free design of the headlights in motor vehicle traffic through polarizing filters.

Es sind bis jetzt trotz vieler Versuche keine derartigen technisch realisierbare Verfahren bekannt, die es ermöglichen würden, auf einfache Art und Weise dieses Problem zu lösen und diese Lösung zum Gegenstand einer Forderung des Verkehrs zu empfehlein.So far, despite many attempts, none of these are technical feasible methods known that would make it possible in a simple manner and Way to solve this problem and make this solution the subject of a requirement of Traffic to be recommended.

Eine völlige blendfreie Gestaltung bei gleichzeitiger Einhaltung der Regeln der Verkehrssicherheit ist nach dem heutigen Stand der Technik bis jetzt nicht gegeben. Die Forderung, zu sehen, gesehen zu werden und dabei nicht geblendet werden, ist bei keinem der sich begegnenden Fahrzeuge bis jetzt realisierbar.A completely glare-free design while maintaining the Rules of traffic safety is according to the current state of the art until now not given. The demand to see, to be seen and not be blinded cannot be implemented in any of the vehicles that meet each other up to now.

Demgegenüber bietet das Verfahren nach der Erfindung die Möglichkeit einer praktisch völlig blendfreien Gestaltung des Scheinwerferlichtes im Kraftfahrzeugverkehr.In contrast, the method according to the invention offers the possibility a practically completely glare-free design of the headlights in motor vehicle traffic.

Die Erfindung zeichnet sich dadurch aus, daß das von der Lichtquelle erzeugte Licht durch Polarisationsfilter in zwei verschiedene, genau senkrecht aufeinander stehende elektrische Ebenen zerlegt wird, wovon eine Ebene beim Austritt aus dem Scheinwerfer, die andere, um 900 gedrehte, beim Durchdringen bzw.The invention is characterized in that the light source light generated by polarization filters in two different, exactly perpendicular to each other standing electrical planes are broken down, one of which is at the exit from the Headlights, the other, turned by 900, when penetrating or

Durchtritt durch die Windschutzscheibe des entgegenkommenden Fahrzeuges oder durch eine entsprechende Brille der Pahrzeuginsassen ausgefiltert wird, sodaß lediglich das von der Straße durch Reflektion entpol/arisierte Licht durch die Windschutzscheibe dringt.Passes through the windshield of the oncoming vehicle or the vehicle occupant is filtered out through appropriate glasses, so that only the light depolarized by reflection from the road through the windshield penetrates.

Die Erfindung setzt also eine in ihrer Polarisationswirkung vorzugsweise einheitliche Ausbildung der Windschutzscheibe bzw. des Brillenfilters einerseits und eine ebenso vorzugsweise einheitliche, jedoch um 900 gedrehte der Scheinwerfer andererseits voraus, wobei beide Filterwirkungen auch durch das Aufkleben von entsprechend gerichteter Polarisationsfolie erzielt werden können. Das von der Straße reflektierte entpolarisierte Licht bleibt jedoch für die sich begegnenden Verkehrsteilnehmer voll sichtbar.The invention thus sets one in its polarization effect preferentially uniform design of the windshield or the glasses filter on the one hand and an equally preferably uniform, but rotated by 900 of the headlights on the other hand ahead, with both filter effects also by sticking accordingly directed polarizing film can be achieved. That reflected from the street However, depolarized light remains for the road users who meet each other fully visible.

Es ist zwar nachweisbar, daß das Licht aus metallischen Reflexen grundsätzlich waagrecht polarisiert ist, sodaß es günstig wäre, die Windschutzscheibe bzw. Brille senkrecht zur Straße zu polarisieren, da dadurch auch andere Reflektionen unterdrückt werden.It can be proven that the light from metallic reflections is basically is horizontally polarized, so it would be beneficial to use the windshield or glasses to polarize perpendicular to the road, as this also suppresses other reflections will.

Ausgeführte Versuche bestätigen folgendes: Bei Verwendung von Filtern mittlerer Qualität wird selbst bei einem Fehlwinkel der Polarisationsebenen zueinander von + - 50, wie sie beispielsweise durch Straßenunebenheiten entstehen können, eine Abdeckung von mindestens 95 % -erreicht, wobei d/er Helligkeitsverlust des reflektierten Lichtes durch die Filter nur gering ist. Dieser Verlust kann in der Praxis durch stärkere Scheinwerferbirnen ausgeglichen werden.Tests carried out confirm the following: When using filters medium quality is achieved even with an incorrect angle of the planes of polarization to one another of + - 50, as they can arise, for example, from uneven road surfaces, one Coverage of at least 95% achieved, with the loss of brightness of the reflected Light through the filter is only slight. This loss can result in practice stronger headlight bulbs are compensated.
