Description
Die Erfindung betrifft eine Beleuchtungsvorrichtung für Fahrzeuge, mit einer Lichtquelle, mit einem Hologrammelement zur Erzeugung eines holografischen Bildes, mit einem Spiegel, der ein von der Lichtquelle abgesandtes Lichtbündel in Richtung des Hologrammelementes umlenkt. The invention relates to a lighting device for vehicles, having a light source, with a hologram element for generating a holographic image, with a mirror which deflects a light beam emitted by the light source in the direction of the hologram element.
Aus der
Aufgabe der vorliegenden Erfindung ist es, eine Beleuchtungsvorrichtung für Fahrzeuge mit einem Hologrammelement derart weiterzubilden, dass es auf einfache Art und Weise zur Erzeugung einer Signallichtfunktion einsetzbar ist, wobei ein möglichst homogenes Erscheinungsbild erzielt wird. Object of the present invention is to develop a lighting device for vehicles with a hologram element such that it can be used in a simple manner to produce a signal light function, with a homogeneous appearance as possible is achieved.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Anspruches 1 dadurch gekennzeichnet, dass eine Hauptachse der Lichtquelle quer zu einer Hauptabstrahlrichtung der Beleuchtungsvorrichtung oder in einen rückwärtigen Raum einer Kammer der Beleuchtungsvorrichtung gerichtet angeordnet ist und dass die Lichtquelle im Bereich eines ersten Seitenrandes des und der Spiegel im Bereich eines zweiten Seitenrandes des Hologrammelementes angeordnet sind. To achieve this object, the invention in conjunction with the preamble of
Der besondere Vorteil der Erfindung besteht insbesondere darin, dass eine Hologrammfunktion in einer Kammer einer Beleuchtungsvorrichtung besonders platzsparend ausgebildet ist. Sowohl die Lichtquelle als auch ein das Licht zum Hologrammelement umlenkender Spiegel sind seitlich zum Hologrammelement angeordnet und nehmen in einer senkrecht zu einer Hauptabstrahlrichtung der Beleuchtungsvorrichtung projizierten Ebene eine relativ kleine Fläche ein. Der Spiegel kann leicht geneigt zur Hauptabstrahlrichtung angeordnet sein. Die Lichtquelle ist quer oder in einem rückwärtigen Bereich der Kammer hin orientiert angeordnet, so dass eine unerwünschte direkte Lichtabstrahlung zur Lichtaustrittsseite hin vermieden wird. Vorteilhaft kann das Hologrammelement einen großen Flächenbereich in einer Erstreckungsebene quer zur Hauptabstrahlrichtung einnehmen. The particular advantage of the invention is in particular that a hologram function is designed to save space in a chamber of a lighting device. Both the light source and a mirror deflecting the light to the hologram element are arranged laterally to the hologram element and occupy a relatively small area in a plane projected perpendicular to a main emission direction of the illumination device. The mirror can be arranged slightly inclined to the main emission direction. The light source is arranged oriented transversely or in a rearward region of the chamber, so that an undesired direct light emission to the light exit side is avoided. Advantageously, the hologram element can occupy a large surface area in an extension plane transversely to the main emission direction.
Nach einer bevorzugten Ausführungsform der Erfindung ist der Lichtquelle eine Sichtblende zugeordnet, so dass die Lichtquelle kaschiert und von außen nicht sichtbar ist. According to a preferred embodiment of the invention, the light source is associated with a screen, so that the light source is laminated and not visible from the outside.
Nach einer bevorzugten Ausführungsform der Erfindung ist das Hologrammelement durch Ausrichtung einer Objektwelle (Objektwellenfeld) und einer Referenzwelle (Referenzwellenfeld) derart erzeugt, dass im Betriebszustand eine nullte Beugungsordnung der das Hologrammelement beleuchtenden Referenzwelle in einem spitzen Winkel zu der Hauptabstrahlrichtung verläuft. Wenn man davon ausgeht, dass die Hauptabstrahlrichtung entgegengesetzt zu einer Beobachtungsrichtung verläuft, wird die mit einem störenden hellen Fleck verbundene nullte Beugungsordnung bei Betrachtung des Hologrammelementes nicht wahrgenommen. According to a preferred embodiment of the invention, the hologram element is produced by aligning an object wave (object wave field) and a reference wave (reference wave field) such that, in the operating state, a zeroth diffraction order of the reference wave illuminating the hologram element is at an acute angle to the main emission direction. Assuming that the main radiation direction is opposite to an observation direction, the zeroth diffraction order associated with an interfering bright spot is not perceived when viewing the hologram element.
Nach einer Weiterbildung der Erfindung ist das Hologrammelement derart ausgebildet, dass ein holografisches Bild zur Erzeugung einer Signallichtfunktion dient. Vorteilhaft kann hierdurch eine Signallichtfunktion mit Tiefenwirkung erzeugt werden, was eine erhöhte Variabilität bei der Konfiguration von Signallichtfunktionen ermöglicht. According to a development of the invention, the hologram element is designed such that a holographic image is used to generate a signal light function. Advantageously, a signal light function with depth effect can thereby be generated, which allows increased variability in the configuration of signal light functions.
Nach einer Weiterbildung der Erfindung sind mehrere Hologrammelemente vorgesehen, denen jeweils eine Lichtquelle zugeordnet ist. Die Hologrammelemente können holografische Bilder gleicher oder unterschiedlicher Formgebung erzeugen, so dass diese sich in unterschiedlichen Ebenen erstrecken können. Auf diese Weise erhält die Kammer der Beleuchtungsvorrichtung im Betriebszustand der Beleuchtungsvorrichtung ein dreidimensionales Erscheinungsbild. Vorteilhaft kann die Bautiefe der Kammer relativ gering gehalten werden. Die holografischen Bilder können auf verschiedenen Ebenen innerhalb der Kammer angeordnet sein, womit eine ansprechende stilistische Anmutung erzeugt wird. Bspw. können die holografischen Bilder im Betriebszustand der Beleuchtungsvorrichtung auf zueinander in der Tiefe versetzten Ebenen erscheinen. According to a development of the invention, a plurality of hologram elements are provided, each associated with a light source. The hologram elements can produce holographic images of the same or different shape so that they can extend in different planes. In this way, the chamber of the lighting device is given a three-dimensional appearance in the operating state of the lighting device. Advantageously, the depth of the chamber can be kept relatively low. The holographic images can be arranged at different levels within the chamber, creating an appealing stylistic appearance. For example. For example, in the operating state of the lighting device, the holographic images may appear at levels offset from each other in depth.
Nach einer Weiterbildung der Erfindung sind benachbart zu einem holografischen Bild eine Anzahl von Optikelementen und jeweils denselben zugeordnete zweite Lichtquellen angeordnet zur Erzeugung einer weiteren Signallichtfunktion. Vorteilhaft kann hierdurch eine Tiefenwirkung der Signallichtfunktion erreicht werden. According to a development of the invention, adjacent to a holographic image, a number of optical elements and in each case the same associated second light sources are arranged for generating a further signal light function. Advantageously, a depth effect of the signal light function can thereby be achieved.
