Abstract
Description
Die Erfindung betrifft einen Fahrzeugscheinwerfer mit einem Gehäuse, einer das Gehäuse abschließenden Abschlussscheibe und zumindest einem in dem Gehäuse angeordneten Reflektor für Fahrlicht, wobei dem Reflektor für Fahrlicht sowohl eine Glühlampe für Fahrlicht, als auch eine Lichtquelle für Positionslicht zugeordnet ist.The The invention relates to a vehicle headlight with a housing, a the housing final Cover disc and at least one arranged in the housing reflector for driving lights, the reflector for Driving light both a light bulb for driving lights, as well as a light source for Position light is assigned.
Aus
der
Aufgabe der Erfindung ist es, einen bekannten Fahrzeugscheinwerfer derart weiterzubilden, dass der Reflektor für Fahrlicht mittels der Lichtquelle für Positionslicht sehr homogen ausgeleuchtet wird.task The invention is a known vehicle headlights such further, that the reflector for driving light by means of the light source for position light is illuminated very homogeneously.
Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffs des Anspruchs 1 dadurch gelöst, dass der Lichtquelle für Positionslicht ein Lichtleitelement zugeordnet ist, welches zumindest eine Lichtumlenkfläche aufweist, die bewirkt, dass das eingekoppelte Licht derart aus dem Lichtleitelement austritt, dass wesentliche Teile des ausgekoppelten Lichts auf die Glühlampe für Fahrlicht auftreffen.These Task becomes in connection with the characteristics of the generic term of the Claim 1 solved by that the light source for Position light is associated with a light guide, which at least a light deflection surface which causes the coupled light in such a way Light guide exits that essential parts of the decoupled Light on the light bulb for driving light incident.
Durch die Umlenkung des Lichts der Lichtquelle für Positionslicht auf die Glühlampe für Fahrlicht wird bewirkt, dass die Lichtstrahlen durch die Lichtquelle für Fahrlicht gestreut und/oder abgelenkt werden, so dass sie auf den Reflektor auftreffen. Diese Beeinflussung des Lichts erfolgt in dem und/oder in der unmittelbaren Nähe des Brennpunktes bzw. Brennortes des Reflektors, so dass die Lichtstrahlen durch diesen genau gerichtet werden, was eine homogene Ausleuchtung des Reflektors und somit ein visuell ansprechendes Erscheinungsbild des Fahrzeugscheinwerfers bewirkt.By the deflection of the light of the light source for position light on the light bulb for driving light is causing the light rays through the light source for driving light scattered and / or deflected, leaving them on the reflector incident. This influence of the light takes place in and / or in the immediate vicinity the focal point or focal point of the reflector, so that the light rays through These are directed exactly what a homogeneous illumination of the Reflectors and thus a visually appealing appearance of the vehicle headlamp causes.
Vorteilhaft trifft das aus dem Lichtleitelement austretende Licht im wesentlichen auf den Glaskolben und/oder die Glühwendel und/oder den Fassungsbereich der Glühlampe auf, so dass es von dort auf den Reflektor gestreut und/oder abgelenkt wird.Advantageous essentially meets the light emerging from the light guide on the glass bulb and / or the filament and / or the socket area the light bulb on, so that it scattered from there to the reflector and / or distracted becomes.
Eine vorteilhafte Ausgestaltung des Fahrzeugscheinwerfers zeichnet sich dadurch aus, dass die Lichtquelle für Positionslicht eine LED ist. Dies bietet insbesondere den Vorteil, dass eine LED nur einen sehr geringen Bauraumbedarf hat. Weiterhin hat eine LED eine Lebensdauer die allgemein der Fahrzeuglebensdauer entspricht, so dass die Lichtquelle für Positionslicht nicht gewechselt werden muss.A advantageous embodiment of the vehicle headlight is characterized characterized in that the light source for position light is an LED. This offers the particular advantage that an LED only a very has low space requirements. Furthermore, an LED has a lifetime which generally corresponds to the vehicle life, so that the light source for position light does not have to be changed.
Bei modernen Fahrzeugen kommen immer häufiger Xenon-Systeme zum Einsatz, die eine andere Farbtemperatur als bekannte Halogen-Systeme aufweisen. Beim Einsatz von bekannten Glühlampen als Lichtquelle für Positionslicht kann sich somit ein Unterschied von 1500 bis 2000K in der Farbtemperatur ergeben, was zu einem visuell unerwünschten Erscheinungsbild führt. Die Farbtemperatur der LED entspricht nahezu der Farbtemperatur von Xenon-Systemen so dass durch den Einsatz einer LED als Lichtquelle für Positionslicht das visuell unerwünschte Erscheinungsbild vermieden wird, was als weiterer Vorteil anzusehen ist.at Xenon systems are increasingly being used in modern vehicles which have a different color temperature than known halogen systems. When using known light bulbs than Light source for Position light can thus make a difference of 1500 to 2000K in the color temperature, resulting in a visually undesirable Appearance leads. The color temperature of the LED is close to the color temperature of xenon systems so that by using an LED as the light source for position light the visually undesirable Appearance is avoided, what to look at as a further advantage is.
Eine weitere vorteilhafte Ausgestaltung der Erfindung zeichnet sich dadurch aus, dass die Lichtquelle für Positionslicht hinter dem Reflektor angeordnet ist. Somit kann die Lichtquelle sehr einfach elektrisch, mechanisch und thermisch kontaktiert werden. Ein weitere Vorteil ist darin zu sehen, dass in dem Reflektor lediglich eine Öffnung vorge sehen werden muss, die geringfügig größer ist als der Querschnitt des Lichtleitelementes.A further advantageous embodiment of the invention is characterized off that light source for Position light is arranged behind the reflector. Thus, the Light source can be easily contacted electrically, mechanically and thermally. Another advantage is the fact that in the reflector only an opening must be seen, which is slightly larger than the cross section of the light-guiding element.
Mittels des Reflektors und der Glühlampe für Fahrlicht wird vorteilhaft eine Lichtverteilung für Fernlicht erzeugt.through of the reflector and the light bulb for driving light Advantageously, a light distribution for high beam is generated.
