Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Fahrzeug-Scheinwerfer nach der Gattung des Anspruchs 1.The The invention is based on a vehicle headlamp of the type of claim 1.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Scheinwerfer der eingangs genannten Art dahingehend auszugestalten und weiterzubilden, dass auch der die Linse zumindest teilweise umgebende Abschnitt beleuchtet erscheint und auf möglichst einfache Art und Weise eine gewünschte Lichtdurchlässigkeit des Abschnitts erreicht werden kann.Of the present invention is based on the object, a headlight of the type mentioned above to design and develop that also the lens at least partially surrounding section Illuminated appears and on as possible simple way a desired light transmission of the section can be reached.
Zur Lösung dieser Aufgabe wird ausgehend von dem Scheinwerfer der gattungsgemäßen Art vorgeschlagen, dass der Scheinwerfer ein Gehäuse aufweist, das in Lichtaustrittsrichtung eine Lichtaustrittsöffnung aufweist, die mit einer lichtdurchlässigen Scheibe abgedeckt ist, wobei in dem Gehäuse eine Einheit umfassend die Lichtquelle, den Reflektor, die Linse und das Trägerelement verstellbar angeordnet ist und wobei der Abschnitt an einer zum Reflektor weisenden inneren Oberfläche zumindest bereichsweise mattiert oder mit einer Beschichtung versehen ist.to solution This object is based on the headlight of the generic type proposed that the headlight has a housing in the light exit direction a light exit opening which is covered with a translucent disk, being in the housing a unit comprising the light source, the reflector, the lens and the carrier element is arranged adjustable and wherein the section at a for Reflector facing inner surface at least partially matted or provided with a coating.
Vorteile der ErfindungAdvantages of the invention
Der erfindungsgemäße Scheinwerfer mit den Merkmalen gemäss dem Anspruch 1 hat den Vorteil, dass auch der die Linse zumindest teilweise umgebende wenigstens annähernd kegelstumpfförmige Abschnitt des Trägerelements beleuchtet erscheint, so dass insgesamt eine größere beleuchtete Fläche vorhanden ist und somit die hell beleuchtete Fläche der Linse nicht oder zumindest weniger störend wahrgenommen wird. Durch die Mattierung und/oder Beschichtung kann die Lichtdurchlässigkeit des Abschnitts beeinflusst werden und eine gewünschte Lichtdurchlässigkeit erreicht werden. Außerdem kann durch die Mattierung und/oder Beschichtung eine Streuung des durch den Abschnitt hindurchtretenden Lichts bewirkt werden. Mit der Erfindung kann die Lichtdurchlässigkeit des Abschnitts beeinflusst werden und die bei dessen Betrachtung von außerhalb des Scheinwerfers wahrnehmbare Beleuchtung auf eine gewünschte Stärke gebracht werden.Of the inventive headlight with the features according to The claim 1 has the advantage that also the lens at least partially surrounding at least approximately frusto-conical section the carrier element Illuminated appears, so that a total of a larger illuminated area available is and therefore the brightly lit surface of the lens is not or at least less disturbing perceived becomes. Due to the matting and / or coating, the light transmission of the section and a desired light transmittance be achieved. In addition, can by the matting and / or coating a scattering of the portion of passing light are effected. With the invention can the light transmission of the section to be influenced and the viewing of it from outside the headlamp perceptible lighting brought to a desired level become.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Scheinwerfers angegeben. Die Ausbildung gemäss Anspruch 5 ermöglicht es, durch das Trägerelement hindurchtretendes Licht in einer vorgegebenen Weise zu verteilen. Durch die optischen Elemente kann durch den Abschnitt hindurchtretendes Licht abgelenkt werden. Wenn hindurchtretendes Licht nach oben abgelenkt wird, sind für die Erzielung der erforderlichen Beleuchtungsstärkewerte oberhalb der Helldunkelgrenze keine zusätzlichen Bauteile beim Scheinwerfer erforderlich.In the dependent claims are advantageous embodiments and refinements of the headlight according to the invention specified. The training according to Claim 5 allows it, through the support element to distribute light passing through in a predetermined manner. Through the optical elements can pass through the section Be distracted light. When passing light is deflected upwards is, are for Achieving the required illuminance values above the light-dark limit no additional components required at the headlight.
