Vorteile der Erfindungadvantages 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 optischen Elemente an dem Abschnitt ist es möglich, durch das Trägerelement hindurchtretendes Licht in einer vorgegebenen Weise zu verteilen. Durch die Streuung des durch den Abschnitt hindurchtretenden Lichts durch die optischen Elemente in einen Bereich oberhalb der Hell-Dunkel-Grenze sind für die Erzielung der erforderlichen Beleuchtungsstärkewerte oberhalb der Helldunkelgrenze keine zusätzlichen Bauteile beim Scheinwerfer erforderlich. Der Scheinwerfer weist ein Lichtmodul umfassend den Reflektor, die Lichtquelle, die Linse und das Trägerelement auf, das in einem Scheinwerfergehäuse verstellbar angeordnet ist.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. Through the optical elements on the section it is possible through the carrier element to distribute light passing through in a predetermined manner. By the scattering of light passing through the section through the optical elements into an area above the cut-off line are for Achieving the required illuminance values above the light-dark limit No additional Components required for the headlamp. The headlight points a light module comprising the reflector, the light source, the lens and the carrier element on, arranged in a headlight housing adjustable is.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Scheinwerfers angegeben. Durch die Ausbildung gemäss Anspruch 8 oder 9 kann die Lichtdurchlässigkeit des Trägerelements beeinflusst werden und die bei dessen Betrachtung von außerhalb des Scheinwerfers wahrnehmbare Beleuchtung auf eine gewünschte Stärke gebracht werden.In the dependent claims are advantageous embodiments and refinements of the headlight according to the invention specified. By training according to claim 8 or 9, the light transmission the carrier element be influenced and when viewed from outside the headlamp perceptible lighting brought to a desired level become.
