Abstract
Description
Die Erfindung bezieht sich auf einen Scheinwerfer für Fahrzeuge mit den im Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen. The invention relates to a headlight for vehicles with the The preamble of claim 1 features specified.
Ein derartiger Scheinwerfer ist aus der DE 196 52 159 A bekannt. Ein besonderes Problem ergibt sich aufgrund der thermischen Belastung für den Lichtleiter, der in der Regel aus Gewichts- und Kostengründen aus Kunststoff besteht. Diese Belastung ist eine zweifache. Zum einen strahlen die für Fern- und/oder Abblendlicht vorgesehenen Lichtquellen Wärme ab. Zum andern tut dies auch die Lichtquelle für die Begrenzungsleuchte selbst, insbesondere dann, wenn das Lichtleitelement allein die Begrenzungsleuchte bildet. Die dabei zu erreichenden Mindestwerte der Beleuchtungsstärke erfordern eine entsprechend starke und dadurch wärmeliefernde Lichtquelle. Gerade bei der aus der DE 196 52 159 A bekannten einseitigen Lichteinkopplung in das Lichtleitelement erfordert dies eine besonders starke Lampe. Such a headlight is known from DE 196 52 159 A. A special Problem arises due to the thermal load on the light guide, which in usually consists of plastic for weight and cost reasons. This Burden is twofold. On the one hand, they shine for high beam and / or low beam provided light sources heat. On the other hand, this also does the light source for the The position lamp itself, especially when the light guide element alone The position lamp forms. The minimum values of the Illuminance requires a correspondingly strong and therefore heat-supplying Light source. Especially in the one-sided known from DE 196 52 159 A. Coupling light into the light-guiding element requires a particularly strong lamp.
Der Erfindung liegt die Aufgabe zu Grunde, einen Scheinwerfer der eingangs genannten Art zu schaffen, bei dem das Lichtleitelement thermisch wesentlich weniger belastet ist. The invention is based on the object, a headlamp of the beginning to create the type mentioned, in which the light-guiding element thermally significantly less is burdened.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. This object is achieved by the features of patent claim 1.
Die thermische Belastung wird durch zwei Merkmale reduziert. Zum einen wird die Begrenzungsleuchtenfunktion zusätzlich oder sogar überwiegend durch das über den Reflektor abgestrahlte Licht übernommen. Zum andern wird nur ein Teil des Lichts der Lichtquelle in das Lichtleitelement eingekoppelt. The thermal load is reduced by two features. For one thing, the Front position lamp function additionally or even predominantly through the above light emitted by the reflector. On the other hand, only a part of the Coupled light of the light source into the light guide.
Durch den im Patentanspruch 2 genannten Zusatzreflektor kann der Anteil des Lichts, der in den Reflektor reflektiert wird, noch besser gesteuert werden. Daraus ergibt sich auch eine entsprechend gezielte Einstellung der thermischen Belastung des Lichtleitelements, da im wesentlichen nur das dort eintretende Licht die thermische Belastung hervorruft. By the additional reflector mentioned in claim 2, the proportion of Light that is reflected in the reflector can be controlled even better. from that there is also a correspondingly targeted setting of the thermal load of the light guide element, since essentially only the light entering there causes thermal stress.
Die im Patentanspruch 3 angegebenen Merkmale dienen der weiteren Verbesserung diese Zusammenspiels aus Zusatzreflektor und der in das Lichtleitelement eintretenden Lichtmenge. Durch den Rand des Reflektors wird in das Lichtleitelement eintretende Licht gesteuert. The features specified in claim 3 serve the further Improvement of this interaction of additional reflector and that in the light guide element amount of light entering. Through the edge of the reflector is in the light guide controlled incoming light.
Schließlich kann durch die Merkmale des Patentanspruchs 4 die thermische Belastung gering gehalten werden, während gleichzeitig das optische Erscheinungsbild vergleichsmäßig ist. Tritt das Licht an beiden Enden in das Lichtleitelement eintritt, läßt sich problemlos eine gleichmäßige Lichtabstrahlung über den gesamten Verlauf des Lichtleitelements erzielen. Finally, by the features of claim 4, the thermal Stress can be kept low while maintaining the visual appearance is comparative. If the light enters the light guide at both ends, uniform light radiation can be easily achieved over the entire course of the light guide element.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Es zeigt Exemplary embodiments of the invention are shown in the drawing. It shows
Fig. 1 einen Scheinwerfer für Fahrzeuge von vorne mit einer erfindungsgemäßen Begrenzungsleuchte, FIG. 1 shows a headlamp for a vehicle from the front with an inventive position lamp,
Fig. 2 die Seitenansicht des Scheinwerfers von Fig. 1. FIG. 2 shows the side view of the headlight from FIG. 1.
Der aus zwei Scheinwerfern 1' und 1" bestehende, in Fig. 1 gezeigte Doppelscheinwerfer 1 enthält in einem Gehäuse G eine Abdeckscheibe 3 und jeweils einen Reflektor 2 sowie Lichtquellen 2' für Abblend- und/oder Fernlicht. In jedem Scheinwerfer 1' und 1" sitzt am Rande des Reflektors 2 ein Zusatzreflektor 4 und durch diesen in der Ansicht von vorne verdeckt, eine Lichtquelle 5, die beide zusammen den Hauptbestandteil des Begrenzungslichts bilden. The two headlamps 1 'double headlight 1 shown and 1 "existing in FIG. 1 includes in a housing G a cover 3 and in each case a reflector 2 as well as light sources 2' for low and / or high beams. In each headlight 1 'and 1 "sits on the edge of the reflector 2 and an additional reflector 4 and conceals it in the view from the front, a light source 5 , both of which together form the main component of the limiting light.
Wie in Fig. 2 zu sehen, reflektiert der Zusatzreflektor 4 das Licht der Lichtquelle 5 in den Reflektor 2. Das daraus austretende Licht realisiert im wesentlichen die Begrenzungslichtfunktion. Ferner verläuft am Umriss jedes Scheinwerfers 1' und 1" ein Lichtleitelement 6, das die Begrenzungslichtfunktion unterstützt. Hierzu wird das Licht der Lichtquelle 5 in die beiden Enden 6 und 6" des Lichtleitelements 6 eingekoppelt (Fig. 3). Dieses Licht tritt über die Länge des Lichtleitelements 6 aus der Oberfläche aus. Die in das Lichtleitelement eintretende Lichtmenge ist durch die Form des Zusatzreflektors gesteuert. Sie kann so eingestellt sein, dass sie und damit die thermische Belastung des Lichtleitelements 6 gering ist. Dadurch ergibt sich eine geringst mögliche thermische Belastung des Lichtleitelements 6. As can be seen in FIG. 2, the additional reflector 4 reflects the light from the light source 5 into the reflector 2 . The light emerging from this essentially realizes the position light function. Furthermore, a light guide element 6 , which supports the limiting light function, runs on the outline of each headlight 1 'and 1 ". For this purpose, the light from the light source 5 is coupled into the two ends 6 and 6 " of the light guide element 6 ( FIG. 3). This light emerges from the surface over the length of the light-guiding element 6 . The amount of light entering the light guide element is controlled by the shape of the additional reflector. It can be set so that it and thus the thermal load on the light-guiding element 6 is low. This results in the lowest possible thermal load on the light-guiding element 6 .
