Abstract
Description
Die Erfindung betrifft eine Fahrzeuglichtanlage mit Fahr- und Begrenzungslicht nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a vehicle lighting system with driving and limiting light according to the preamble of claim 1.
Fahrzeuglichtanlagen umfassen im Frontbereich zur Beleuchtung hauptsächlich in Fahrrichtung gewöhnlich ein Fahrlicht, das zwischen Fernlicht und Abblendlicht umschaltbar ist, und ein Begrenzungslicht. Das Begrenzungslicht ist meist vorschriftsmäßig auch im Abblendlicht- und Fernlichtbetrieb des Fahrlichtes aktiviert.Vehicle lighting systems usually include in the front area for lighting mainly in the direction of travel Driving light, which is switchable between high beam and low beam, and a limiting light. The limiting light is usually also in accordance with regulations activated in low beam and high beam operation of the driving light.
Zur
Erzeugung der Lichtstrahlung für
die verschiedenen Beleuchtungsarten sind in der Regel für jede Beleuchtungsart
jeweils eine Lichtquelle, ein Reflektor und eine Linsenanordnung
vorgesehen, wobei die Beleuchtung für das Abblendlicht sein kann.
So ist in der
In
der
Aufgabe der Erfindung ist es, eine Fahrzeuglichtanlage mit einer optimierten Begrenzungslichtfunktion anzugeben.task The invention is a vehicle lighting system with an optimized Specify limiting light function.
Die Erfindung löst diese Aufgabe durch Bereitstellung einer Fahrzeuglichtanlage mit den Merkmalen des Patentanspruchs 1.The Invention solves this object by providing a vehicle lighting system with the features of claim 1.
Vorteilhafte Ausführungsformen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.advantageous embodiments and further developments of the invention are specified in the dependent claims.
Erfindungsgemäß umfasst die Fahrzeuglichtanlage ein Lichtleitsystem, mit dem ein Teil der im Fahrlichtbereich erzeugten Lichtstrahlung aus dem Fahrlichtbereich ausgekoppelt und in einen Begrenzungslichtbereich einkoppelt werden kann. Dies ermöglicht eine Anpassung des Begrenzungslichtes an das Fahrlicht und eine Steigerung der Ausnutzung der im Fahrlichtbereich erzeugten Lichtstrahlung.According to the invention the vehicle lighting system is a lighting control system with which part of the in the driving light area generated light radiation from the driving light area be coupled out and coupled into a limiting light range can. this makes possible an adaptation of the limiting light to the driving light and a Increase the utilization of the light radiation generated in the driving light area.
Durch die definierte Lichtleitung von Lichtstrahlung aus dem Fahrlichtbereich in den Begrenzungslichtbereich kann das Begrenzungslicht beispielsweise in den Parametern Farbe und/oder Farbtemperatur und/oder Helligkeit und/oder Homogenität an das Abblendlicht und/oder das Fernlicht angepasst werden. Dadurch kann im Frontbereich des Fahrzeugs ein vergleichsweise einheitliches Nachtdesign der aktivierten Beleuchtungsmittel erzielt werden, insbesondere auch bei Fahrzeuglichtanlagen mit Xenon-Fahrlicht. Da Xenon-Fahrlichter relativ weiße Lichtstrahlung erzeugen und das Begrenzungslicht in der Regel mit einer Glühlampe Lichtstrahlung mit gelblicher Farbwirkung erzeugt, ergibt sich bei entsprechenden herkömmlichen Fahrzeugen im Frontbereich des Fahrzeugs ein Nachtdesign mit uneinheitlicher Lichtfarbwirkung. Durch das erfindungsgemäße Auskoppeln von Lichtstrahlung aus dem Fahrlichtbereich und das zugehörige Einkoppeln in den Begrenzungslichtbereich lässt sich in vorteilhafter Weise die Farbwirkung des Begrenzungslichtbereichs an diejenige des Fahrlichtbereichs anpassen und ein gewünschtes einheitliches Nachtdesign erzeugen.By the defined light pipe of light radiation from the driving light area in the limiting light range, the limiting light, for example in the parameters color and / or color temperature and / or brightness and / or homogeneity be adapted to the low beam and / or the high beam. Thereby Can in the front of the vehicle a comparatively uniform Night design of the activated lighting means are achieved, in particular also in vehicle lighting systems with xenon headlights. Because xenon driving lights relatively white Generate light radiation and the limiting light usually with a light bulb Light radiation produced with yellowish color effect, results at corresponding conventional Vehicles in the front of the vehicle a night design with inconsistent Light color effect. By the decoupling of light radiation according to the invention from the driving light area and the associated coupling into the limiting light area let yourself advantageously the color effect of the limiting light range adapt to that of the driving light area and a desired Create a uniform night design.
In Ausgestaltung der Fahrzeuglichtanlage wird im Wesentlichen von einer Lichtquelle des Fahrlichtbereichs emittiertes Streulicht aus dem Fahrlichtbereich auskoppelt und in den Begrenzungslichtbereich eingekoppelt.In Design of the vehicle lighting system is essentially a Light source of the driving light area emitted scattered light from the Headlight range decoupled and coupled into the limiting light range.
Zur geeigneten Erzeugung bzw. Abstrahlung des Begrenzungslichtes und/oder zur eigenständigen Designwahl für das Begrenzungslicht sind im Begrenzungslichtbereich vorzugsweise eine separate Lichtquelle und/oder ein Begrenzungslicht-Reflektor oder/und eine Begrenzungslicht-Lichtscheibe und/oder ein Begrenzungslicht-Abdeckrahmen und/oder ein Begrenzungslicht-Lichtleiter angeordnet. Dies gewährleistet einen vorgeschriebenen bzw. einen erwünschten Betrieb des Begrenzungs lichtes im Fahrzeugstandbetrieb sowie im Abblendlichtbetrieb und im Fernlichtbetrieb des Fahrzeugs.to suitable generation or emission of the limiting light and / or to standalone Design choice for the limiting light is preferable in the limiting light area a separate light source and / or a limiting light reflector and / or a limiting light lens and / or a limiting light cover frame and / or a limiting light optical fiber arranged. This ensures a prescribed or a desired operation of the limiting light in Vehicle standstill operation as well as in low beam operation and in high beam operation of the vehicle.
In weiterer Ausgestaltung umfasst das Lichtleitsystem als ein jeweiliges lichtumlenkendes oder lichtverteilendes Element mindestens einen Spiegel und/oder einen Reflektor und/oder ein Prisma und/oder einen Lichtleiter und/oder einen Abdeckrahmen.In a further embodiment, the light guide system comprises as a respective light-deflecting or light-distributing element at least one mirror and / or a reflector and / or a prism and / or a light guide and / or a cover frame.
Das Lichtleitsystem zur Auskopplung der Lichtstrahlung aus dem Fahrlichtbereich ist mit einem eintrittsseitigen Teil beispielsweise in einem radialen Abstand von einer optischen Achse des Fahrlichtbereichs angeordnet.The Light guide system for decoupling the light radiation from the driving light area is with an entrance-side part, for example, at a radial distance arranged from an optical axis of the driving light area.
Zusätzlich oder alternativ kann ein eintrittsseitiger Teil des Lichtleitsystems zur Auskopplung der Lichtstrahlung aus dem Fahrlichtbereich beispielsweise axial vor einer Linsenanordnung und/oder hinter einem Reflektor des Fahrlichtbereichs und/oder axial zwischen der Linsenanordnung und dem Reflektor angeordnet sein.Additionally or Alternatively, an inlet-side part of the light guide system for decoupling the light radiation from the driving light area, for example axially in front of a lens arrangement and / or behind a reflector the driving light area and / or axially between the lens arrangement and be arranged the reflector.
In Ausgestaltung der Fahrzeuglichtanlage koppelt das Lichtleitsystem die aus dem Fahrlichtbereich ausgekoppelte Lichtstrahlung in die Lichtscheibe und/oder auf den Reflektor und/oder in den Abdeckrahmen und/oder in den Lichtleiter des Begrenzungslichtbereichs ein.In Design of the vehicle lighting system couples the light control system the decoupled from the driving light area light radiation in the Lens and / or on the reflector and / or in the cover frame and / or in the light guide of the limiting light range.
