Description

Korbförmige, aus Lamellen zusammengesetzte Abblendvorrichtung für elektrische Scheinwerfer Das Patent 637 544 betrifft eine Abblendvorrichtung, die in Verbindung mit einer gewöhnlichen Zweifadenglühlampe eine Abblendwirkung dadurch erzeugt, daß die aus Lamellen zusammengesetzte Vorrichtung in der oberen Hälfte eines elektrischen Scheinwerfers eingebaut ist und durch Reflexion an dieser Vorrichtung die Lichtstrahlen des Nahlichtfadens nach Verlassen des Scheinwerferspiegels zur Scheinwerferachse zugerichtet sind. In der unteren bzw. in der von der Vorrichtung nicht bedeckten Stelle des Scheinwerferspiegels verlassen die Lichtstrahlen den Scheinwerferspiegel unbeeinflußtlediglich bedingt durch den vorhandenen Einfallswinkel.Basket-shaped dimming device composed of lamellas for electric headlights Patent 637,544 relates to a dimming device which In connection with a normal two-filament light bulb, this results in a dimming effect produced that the device composed of lamellas in the upper half an electric headlight is installed and by reflection on this device the light rays of the Nahlichtfadens after leaving the headlight mirror for Headlight axis are trimmed. In the lower or in the of the device The light rays leave the uncovered area of the headlight mirror Headlight mirror unaffected only due to the existing angle of incidence.

Beträgt der Schnittwinkel der Lamellen nach dem Patent 637 544 beispielsweise 18o° und ist die Vorrichtung so im Scheinwerfer eingebaut, daß die bei dem Schnittwinkel von I8o° ebene Begrenzungsfläche derselben horizontal verläuft, so ist der Lichtaustritt auf beiden Seiten der Scheinwerferachse symmetrisch.For example, if the angle of intersection of the lamellas is 637,544 18o ° and the device is installed in the headlight so that the angle of intersection of 180 ° flat boundary surface of the same runs horizontally, the light is emitted symmetrical on both sides of the headlight axis.

Es ist nun manchmal erwünscht, einen unsymmetrischen Strahlengang zu erzielen. Beispielsweise soll das Abblendlicht bei Rechtsfahrordnung nicht nur nach unten geneigt, sondern gleichzeitig auchetwas aus der Fahrrichtung nach rechts abgelenkt werden. Hierdurch tritt bei sich ausweichenden Fahrzeugen eine günstige Beeinflussung der Gesamtbeleuchtung ein. Der vorhandene Lichtstrom wird teilweise aus der Richtung des entgegenkommenden Fahrzeuges weggenommen, wodurch die Blendwirkung weiterhin wesentlich verringert wird und zur Aufhellung der rechten Straßenweite vor dem eigenen Fahrzeug verwendet.It is now sometimes desirable to have an asymmetrical beam path to achieve. For example, the low beam should not only be used in right-hand traffic inclined downwards, but at the same time also slightly out of the direction of travel to the right to get distracted. As a result, if vehicles evasive, a favorable one occurs Influencing the overall lighting. The existing luminous flux is partially taken away from the direction of the oncoming vehicle, reducing the dazzling effect continues to be significantly reduced and to lighten the right street width used in front of your own vehicle.

Zur Erreichung dieser Wirkung wird erfindungsgemäß die Abblendvorrichtung gemäß Patent 637 544 so ausgeführt, daß der Schnittwinkel der Lamellen. größer als i8o° ist und daß hierbei die Vorrichtung so im Scheinwerfer eingebaut wird, daß dieselbe unsymmetrisch zur horizontalen Mittelebene des Scheinwerfers liegt; bei einer anzustrebenden Rechtsablenkung wird hierbei die Abblendvorriehtung links unter die Mittelebene des Scheinwerfers, herabgezogen, in der Ausstrahlungsrichtung des Scheinwerfers gesehen. Zur Erzielung einer evtl. gewollten Linksabdrängung des Lichtstromes von der vertikalen Mittelebene wird die Abblendvo richtung sinngemäß in der rechten Sclhein werferhälfte unter die horizontale Mittelebene herabgezogen.According to the invention, the masking device is used to achieve this effect designed according to patent 637 544 so that the angle of intersection of the lamellas. greater than i8o ° and that the device is installed in the headlight in such a way that the same is asymmetrical to the horizontal center plane of the headlight; at A right deflection to be aimed for is here the anti-dazzle device on the left below the middle plane of the headlight, pulled down, in the direction of emission seen the headlight. To achieve a possibly desired left displacement of the Luminous flux from the vertical center plane, the dimming direction is analogous in the right half of the headlamp pulled down below the horizontal median plane.
