Abstract
Die vorliegende Erfindung betrifft eine Leuchte für Fahrzeuge mit einem Gehäuse (3), einer in dem Gehäuse (3) angeordneten Lichtquelle (1) und einer farbigen Lichtscheibe (4), durch die der Gehäuseinnenraum zumindest zum Teil einsehbar ist. Die erfindungsgemäße Leuchte ist dadurch gekennzeichnet, dass ein Teil der Oberflächen im Gehäuseinnenraum dunkel ausgebildet ist.The The present invention relates to a lamp for vehicles with a housing (3), one in the housing (3) arranged light source (1) and a colored lens (4), through which the housing interior at least partially visible. The luminaire according to the invention is characterized in that a part of the surfaces in Housing interior is dark.
Description
Die vorliegende Erfindung betrifft eine Leuchte für Fahrzeuge, insbesondere Kraftfahrzeuge, mit einem Gehäuse, einer in dem Gehäuse angeordneten Lichtquelle und einer farbigen Lichtscheibe, durch die der Gehäuseinnenraum zumindest zum Teil einsehbar ist.The The present invention relates to a light for vehicles, in particular motor vehicles, with a housing, one in the housing arranged light source and a colored lens through the housing interior at least partially visible.
Derartige Leuchten sind insbesondere am Heck des Fahrzeugs als Brems- oder Schlusslicht bekannt. Nachteilhaft an bekannten Leuchten ist jedoch, dass der Gehäuseinnenraum bei ausgeschalteter Leuchte, d.h. wenn die Lichtquelle kein Licht emittiert, vollständig einsehbar ist. Dies beeinflusst das Erscheinungsbild der Leuchte nachteilhaft.such Lights are especially at the rear of the vehicle as a brake or Taillight known. A disadvantage of known luminaires, however, is that the housing interior when the light is switched off, i. if the light source does not emit light, Completely is visible. This affects the appearance of the lamp disadvantageous.
Zur Lösung dieses Problems ist vorgeschlagen worden, eine dunklere Lichtscheibe zu verwenden, um zu verhindern, dass der Gehäuseinnenraum einsehbar ist. Bei dieser Lösung ergeben sich jedoch Probleme für die Lichtfunktionen der Leuchte, wenn sie eingeschaltet ist. Eine dunklere Lichtscheibe absorbiert zu viel Licht, so dass die einwandfreie Funktion der Leuchte nicht gewährleistet werden kann. Ggf. werden auch gesetzlich vorgeschriebene Lichtwerte nicht erreicht.to solution This problem has been suggested, a darker lens to use, to prevent the housing interior is visible. In this solution However, problems arise for the light functions of the luminaire when it is switched on. A darker lens absorbs too much light, leaving the flawless Function of the lamp is not guaranteed can be. Possibly. are also legally prescribed light values not reached.
Es ist die Aufgabe der vorliegenden Erfindung, eine Leuchte der eingangs genannten Art bereitzustellen, bei der die Möglichkeit in den Gehäuseinnenraum einzusehen verringert wird.It The object of the present invention is a luminaire of the beginning to provide said type, in which the possibility in the housing interior is reduced.
Diese Aufgabe wird erfindungsgemäß durch eine Leuchte mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen dieser Leuchte ergeben sich aus den Unteransprüchen.These The object is achieved by a Luminaire solved with the features of claim 1. Advantageous training and further education This lamp will become apparent from the dependent claims.
Die erfindungsgemäße Leuchte ist dadurch gekennzeichnet, dass ein Teil der Oberfläche im Gehäuseinnenraum dunkel ausgebildet ist. Von diesen dunklen Oberflächen im Gehäuseinnenraum wird weniger Licht reflektiert oder gestreut als von herkömmlichen hellen oder spiegelnden Oberflächen. Dies hat zur Folge, dass im ausgeschalteten Zustand der Leuchte weniger bzw. gar kein Licht durch die farbige Lichtscheibe nach au ßen abgegeben wird. Das Erscheinungsbild der Leuchte von außen ist daher dunkler. Man kann in diesem Fall im Wesentlichen nicht in den Gehäuseinnenraum hineinsehen.The Lamp according to the invention is characterized in that a part of the surface in the housing interior is dark. From these dark surfaces in the Housing interior Less light is reflected or scattered than conventional bright or reflective surfaces. This As a result, when switched off the light less or no light emitted through the colored lens to the outside becomes. The appearance of the lamp from the outside is therefore darker. you in this case, essentially not in the housing interior see inside.
Der Absorptionskoeffizient der dunklen Oberflächen ist insbesondere höher als derjenige von verchromten und/oder Aluminium bedampften Oberflächen. Er ist insbesondere so groß, dass bei ausgeschalteter Leuchte von den dunklen Oberflächen im Wesentlichen kein Licht durch die Lichtscheibe durchtritt. Sie sind somit von außen bei ausgeschalteter Leuchte nicht sichtbar.Of the Absorption coefficient of the dark surfaces is especially higher than that of chromed and / or aluminum vaporized surfaces. He is especially so big with the light off, the dark surfaces in the Essentially no light passes through the lens. you are thus from the outside not visible when the light is off.
Gemäß einer Weiterbildung der erfindungsgemäßen Leuchte ist die Lichtquelle von einem Reflektor umgeben. Gemäß einer Ausgestaltung sind die dunklen Oberflächen außerhalb des Reflektors gebildet. Gemäß einer anderen Ausgestaltung weist der Reflektor lichttechnisch wirksame Flächen und lichttechnisch nicht wirksame Flächen auf. In diesem Fall sind die dunklen Oberflächen zumindest zum Teil auch von lichttechnisch nicht wirksamen Flächen des Reflektors gebildet. Die lichttechnisch wirksamen Flächen des Reflektors dienen dazu, das von der Lichtquelle emittierte Licht so zu richten, dass die jeweilige Lichtfunktion der Leuchte erfüllt wird. Lichttechnisch nicht wirksame Flächen des Reflektors tragen zur Realisierung der jeweiligen Lichtfunktion im Wesentlichen nicht bei, so dass diese Flächen ohne Beeinträchtigung der Lichtfunktion der Leuchte dunkel und insbesondere nicht spiegelnd ausgebildet sein können.According to one Development of the lamp according to the invention the light source is surrounded by a reflector. According to one Embodiment, the dark surfaces are formed outside the reflector. According to one In another embodiment, the reflector has lighting technology effective surfaces and non-technically effective surfaces. In this case are the dark surfaces at least in part also of non-photorefractive surfaces of the reflector educated. The photometrically effective surfaces of the reflector serve to direct the light emitted by the light source so that the respective light function of the luminaire is fulfilled. Not technically effective surfaces of the reflector contribute to the realization of the respective light function essentially not at all, so that these areas without interference the light function of the lamp is dark and in particular not reflective can be trained.
Gemäß einer bevorzugten Ausgestaltung der erfindungsgemäßen Leuchte ist die Lichtscheibe rot gefärbt und die dunklen Oberflächen im Gehäuseinnenraum sind rot, dunkelrot und/oder schwarz. Es handelt sich in diesem Fall um eine Heckleuchte eines Fahrzeugs. Durch sie können die Schlusslicht- und Bremslichtfunktion sowie ggf. weitere Lichtfunktionen realisiert sein.According to one preferred embodiment of the lamp according to the invention, the lens is red colored and the dark surfaces in the housing interior are red, dark red and / or black. It is in this Case around a tail light of a vehicle. Through them, the Taillight and brake light function and possibly other lighting functions be realized.
Gemäß einer weiteren bevorzugten Ausgestaltung sind die dunklen Oberflächen lackiert.According to one Another preferred embodiment, the dark surfaces are painted.
Die Erfindung wird nun anhand eines Ausführungsbeispiels mit Bezug zu den Zeichnungen erläutert.The Invention will now be described with reference to an embodiment with reference to explained the drawings.
