Die vorliegende Erfindung betrifft eine Verbundglasscheibenvorrichtung und ein Verfahren zum Steuern einer Verbundglasscheibenvorrichtung.

Diese phototrope Fensterscheibe ist jedoch nicht entsprechend der Anforderung eines Bedieners, d.h. eines Fahrzeuginsassen, steuerbar, sondern reagiert lediglich auf eine Sonneneinstrahlung. However, this photochromic windowpane is not according to the requirement of an operator, i. a vehicle occupant, controllable, but only responds to sunlight.
Es ist die Aufgabe der vorliegenden Erfindung, eine Verbundglasscheibenvorrichtung mit einer phototropen Schicht und ein Verfahren zum Steuern einer derartigen Verbundglasscheibenvorrichtung zu schaffen, wobei ein Transmissionsgrad der Verbundglasscheibe auf Anforderung steuerbar ist. It is the object of the present invention to provide a laminated glass pane device with a photochromic layer and a method for controlling such a laminated glass pane device, wherein a transmittance of the laminated glass pane is controllable upon request.
Diese Aufgabe wird durch eine Verbundglasscheibenvorrichtung gelöst, die die Merkmale von Patentanspruch 1 aufweist. Ferner wird diese Aufgabe durch ein Verfahren zum Steuern einer Verbundglasscheibenvorrichtung gelöst, das die Merkmale von Patentanspruch 11 aufweist. This object is achieved by a laminated glass pane device having the features of
Vorteilhafte Weiterbildungen sind in den abhängigen Patentansprüchen genannt. Eine erfindungsgemäße Verbundglasscheibenvorrichtung weist eine Verbundglasscheibe mit einer phototropen Schicht, eine künstliche Lichtquelle, die Licht mit einem Wellenlängenspektrum erzeugt, die einen Transmissionsgrad der phototropen Schicht verändert, eine Kopplungseinrichtung zum Einkoppeln von Licht der künstlichen Lichtquelle in die phototrope Schicht und eine Steuerung zum Steuern der künstlichen Lichtquelle derart auf, dass der Transmissionsgrad der phototropen Schicht veränderbar ist. Mit Licht ist eine elektromagnetische Strahlung in einem für das menschliche Auge sichtbaren und unsichtbaren Bereich bezeichnet. Die künstliche Lichtquelle ist eine Strahlenquelle für diese elektromagnetische Strahlung. Advantageous developments are mentioned in the dependent claims. A laminated glass panel device according to the present invention comprises a laminated glass with a photochromic layer, an artificial light source which generates light having a wavelength spectrum which changes a transmittance of the photochromic layer, a coupling means for coupling light of the artificial light source into the photochromic layer and a controller for controlling the artificial one Light source such that the transmittance of the photochromic layer is changeable. Light refers to electromagnetic radiation in a visible and invisible area to the human eye. The artificial light source is a radiation source for this electromagnetic radiation.
Die phototrope Schicht ist insbesondere eine photochrome Schicht, deren Farbe veränderbar ist. In particular, the photochromic layer is a photochromic layer whose color is changeable.
Durch das Einkoppeln von Licht mit einer geeigneten Wellenlänge in die phototrope Schicht kann der Transmissionsgrad der Verbundglasscheibe insgesamt unabhängig von einer Sonneneinstrahlung verändert werden. Bevorzugt ist die Kopplungseinrichtung derart angepasst, dass Licht in eine zu der phototropen Schicht benachbarte, insbesondere unmittelbar angrenzende, Lichtleitschicht einzukoppeln. Die Lichtleitschicht ist angepasst, das eingekoppelte Licht der künstlichen Lichtquelle in die phototrope Schicht abzustrahlen. Hierdurch kann die phototrope Schicht über eine größere Fläche im Wesentlichen gleichmäßig mit dem den Transmissionsgrad verändernden Licht beaufschlagt werden, sodass der Transmissionsgrad der Verbundglasscheibe insgesamt gleichmäßig verändert werden kann. By coupling light with a suitable wavelength into the photochromic layer, the transmittance of the laminated glass pane as a whole can be changed independently of solar radiation. The coupling device is preferably adapted in such a way that light is coupled into a light-conducting layer adjacent to the photochromic layer, in particular directly adjacent to it. The light guiding layer is adapted to radiate the coupled light of the artificial light source into the photochromic layer. As a result, the photochromic layer can be acted upon substantially uniformly over a larger area by the light which changes the transmittance, so that the transmittance of the laminated glass pane as a whole can be uniformly changed.
Gemäß einer bevorzugten Weiterbildung kann die Kopplungseinrichtung angepasst sein, das Licht der künstlichen Lichtquelle über einen Rand, d.h. einer Stirnseite, der Verbundglasscheibe einzukoppeln. According to a preferred embodiment, the coupling device can be adapted to control the light of the artificial light source via an edge, i. an end face to couple the laminated glass pane.
Hierdurch kann die Kopplungseinrichtung außerhalb eines Sichtbereichs der Verbundglasscheibe angeordnet werden. As a result, the coupling device can be arranged outside a viewing region of the laminated glass pane.
Weiterhin weist die Verbundglasscheibe der erfindungsgemäßen Verbundglasscheibenvorrichtung vorteilhaft zumindest eine Filterschicht auf, die für Licht in einem Wellenlängenspektrum, das den Transmissionsgrad der phototropen Schicht verändert, undurchlässig oder zumindest lediglich eingeschränkt durchlässig ist. Furthermore, the laminated glass pane of the laminated glass pane device according to the invention advantageously has at least one filter layer which is opaque or at least only partially permeable to light in a wavelength spectrum which alters the transmittance of the photochromic layer.
Die Filterschicht kann somit verhindern, dass bspw. Sonnenlicht oder Licht von einer anderen Lichtquelle den Transmissionsgrad der phototropen Schicht ungewünscht verändert. The filter layer can thus prevent, for example, sunlight or light from another light source from undesirably changing the transmittance of the photochromic layer.
Vorteilhaft ist auf jeder Seite der phototropen Schicht eine entsprechende Filterschicht ausgebildet. Advantageously, a corresponding filter layer is formed on each side of the photochromic layer.
Somit ist zuverlässig verhindert, dass von keiner Seite der Verbundglasscheibe Sonnenlicht oder Licht von einer anderen Lichtquelle, das den Transmissionsgrad der Verbundglasscheibe ungewünscht verändern könnte, auf die phototrope Schicht trifft. Thus, it is reliably prevented from meeting the photochromic layer from either side of the laminated glass of sunlight or light from another light source, which could undesirably alter the transmittance of the laminated glass pane.
Gemäß einer bevorzugten Weiterbildung erzeugt die Lichtquelle im Wesentlichen unsichtbares Licht im ultravioletten Wellenlängenspektrum, d.h. UV-Licht. According to a preferred embodiment, the light source generates substantially invisible light in the ultraviolet wavelength spectrum, i. UV light.
UV-Licht ist dahingehend vorteilhaft, da es für das menschliche Auge nicht sichtbar ist. UV light is advantageous in that it is invisible to the human eye.
Die Lichtquelle kann dabei vorteilhaft eine Halbleiterlichtquelle, d.h. eine Licht emittierende Diode bspw. eine UV-Diode sein. The light source may advantageously be a semiconductor light source, i. a light-emitting diode, for example, be a UV diode.
Eine Halbleiterlichtquelle ist besonders kostengünstig herstellbar und verbraucht eine geringe Menge an Energie. A semiconductor light source is particularly inexpensive to produce and consumes a small amount of energy.
Gemäß einer weiteren bevorzugten Weiterbildung weist die Verbundglasscheibe eine Wärmeschutzschicht auf, sodass diese nicht auf die phototrope Schicht trifft. According to a further preferred development, the laminated glass pane has a heat protection layer so that it does not strike the photochromic layer.
Dies ist dahingehend vorteilhaft, da die phototrope Schicht ihre Eigenschaften bei Vorhandensein von Wärmestrahlen verändert. This is advantageous in that the photochromic layer changes its properties in the presence of heat rays.
Insbesondere reflektiert die Wärmeschutzschicht Licht bzw. Strahlung des Infrarotspektrums. In particular, the heat protection layer reflects light or radiation of the infrared spectrum.
Die Verbundglasscheibe weist ferner bevorzugt äußere Glasschichten auf. The laminated glass pane further preferably has outer glass layers.
Die phototrope Schicht kann auch lediglich in einen Teilbereich der Verbundglasscheibe ausgebildet sein, so dass ein Abschnitt der Verbundglasscheibe im Transmissionsgrad veränderbar ist. The photochromic layer can also be formed only in a partial region of the laminated glass pane, so that a portion of the laminated glass pane in the transmittance can be changed.
Die Verbundglasscheibe kann eine Scheibe eines Kraftfahrzeugs, bspw. eine Frontscheibe, eine Heckscheibe, eine Seitenscheibe oder eine Dachscheibe sein. The laminated glass pane may be a pane of a motor vehicle, for example a windscreen, a rear window, a side window or a roof window.
Die Verbundglasscheibenvorrichtung kann auch in jedem anderem Bereich, in dem Glasscheiben angewendet werden, wie beispielsweise an Gebäuden, eingesetzt werden. The laminated glass pane device may also be used in any other area where glass sheets are applied, such as buildings.
Bevorzugt ist die Steuerung angepasst, eine Lichtdurchlässigkeit und/oder einen Tönungsgrad der Verbundglasscheibe entsprechend einer Bedieneranforderung zu steuern. Preferably, the controller is adapted to control a light transmittance and / or a degree of tinting of the laminated glass pane according to an operator request.
Ferner betrifft die vorliegende Erfindung ein Verfahren zum Steuern einer Verbundglasscheibenvorrichtung mit einer Verbundglasscheibe, die eine phototrope Schicht aufweist mit den Schritten Steuern, d.h. Ein- und Ausschalten, einer künstlichen Lichtquelle, und Einkoppeln von Licht der künstlichen Lichtquelle in die phototrope Schicht. Vorstehend beschriebene Merkmale der Erfindung können soweit möglich und sinnvoll beliebig miteinander kombiniert werden. Furthermore, the present invention relates to a method of controlling a laminated glass pane device with a laminated glass pane having a photochromic layer comprising the steps of controlling, i. Turning on and off, an artificial light source, and coupling light of the artificial light source in the photochromic layer. The features of the invention described above can be combined as far as possible and meaningful with each other.
