Abstract

A multiple-plate insulating glass complex with at least two plane-parallel glass plates (1 and 2) located at a distance from one another and a light deflection system arranged between these, for example in the form of a prism-plate (6). It is envisaged that between the light output side of the prism plate (6) and the lower side of the adjacent glass plate a light-scattering medium is arranged which is of such a nature that the surface (8) of the adjacent glass plate (2) turned toward the prism plate (8) is specially processed, for example etched or sand-blasted. The light-scattering medium can, furthermore, be an interference-layer (9) which consists for example of a matt-finished foil. In addition, glass plate (2) placed on the light output side can also be designed as a composite safety glass with approximately processed surfaces; a light-scattering mat (10) or other suitable materials can also be fitted.

Description

Mehrscheiben-Isolierglaseinheit mit integriertem licktlenkenden System Multi-pane insulating glass unit with integrated lick-steering system
Die Erfindung betrifft eine Mehrscheiben-Isolierglas-Einheit mit mindestens zwei, in einem Abstand voneinander und planparallel angeordneten Glasscheiben und einem, zwischen diesen angeordneten lichtlenkenden System, beispielsweise in Form einer Prismenplatte.The invention relates to a multi-pane insulating glass unit with at least two glass panes arranged at a distance from one another and plane-parallel and with a light-guiding system arranged between them, for example in the form of a prismatic plate.
Solche bekannten Mehrscheiben-Isolierglas-Einheiten werden zur Belichtung von Räumen eingesetzt, bei welchen erhöhte Anforderungen an eine gleichmässige und das Tageslicht intensiv ausnutzende Ausleuchtung gestellt werden oder bei welchen eine gezielte Lenkung des Lichts bei gleichzeitiger Ausschaltung von direkter Blendung erwünscht ist. Die zwischen mindestens zwei Glasscheiben angeordneten Prismenscheiben bzw. -platten lenken das aufgefangene Tageslicht je nach Ausrichtung der Prismenoberfläche gezielt in die zu belichtenden Räumlichkeiten, wobei selbstverständlich eine gleichmässige Lichtverteilung gewünscht ist.Known multi-pane insulating glass units of this type are used for illuminating rooms in which increased demands are placed on uniform and intensive use of daylight or in which a targeted control of the light with simultaneous switching off of direct glare is desired. The prism panes or plates arranged between at least two glass panes direct the captured daylight depending on the orientation of the prism surface into the rooms to be exposed, of course a uniform light distribution is desired.
Die zum Innenraum gerichteten Prismen, insbesondere verspiegelte Prismen, zerlegen das Sonnenlicht durch Brechung in Spektralfarben. Ein Teil dieses spektral aufgespaltenen Lichtes tritt jedoch aufgrund von Fehlstrahlungen durch die Prismenplatte hindurch und kann sich sichtbar in dem zu belichtenden Raum als farbiges Licht zeigen bzw. an Gegenständen und Wänden abbilden. Diese Erscheinungen können sich nachteilig insbesondere auch für die lichtmässige Nutzung des belichteten Raumes auswirken.The prisms facing the interior, in particular mirrored prisms, break up the sunlight by refraction into spectral colors. Part of this spectrally split light, however, passes through the prismatic plate due to false radiation and can be seen in the space to be exposed as colored light or can be shown on objects and walls. These phenomena can also have a disadvantage, in particular for the lighting use of the exposed room.
Aufgabe der Erfindung ist es deshalb, den Austritt solcher spektral zerlegter Lichtanteile aus den Mehrscheiben-Isoliergläs-Einheiten zu vermeiden, so dass eine gleichmässige und vor allen Dingen neutrale einfarbige Raumbeleuchtung erzielt wird.The object of the invention is therefore to spectral the exit of such to avoid disassembled light components from the multi-pane insulating glass units, so that uniform and above all neutral monochrome room lighting is achieved.
Diese Aufgabe wird bei einer Mehrscheiben-Isolierglas-Einheit der eingangs genannten Art dadurch gelöst, dass zwischen der Lichtaustrittsseite der Prismenplatte und der Unterseite der benachbarten Glasscheibe ein lichtstreuendes Mittel vorgesehen ist. Dieses lichtstreuende Mittel vermischt die heraustretenden Fehlstrahlungen der durch die Prismenplatte spektral zerlegten Lichtanteile wieder zu weissem Licht. Ein solches lichtstreuendes Mittel ist beispielsweise in Form der besonders bearbeiteten, der Prismenplatte zugekehrten Oberfläche der benachbarten Glasscheibe vorgesehen, wobei die Oberfläche dieser Glasscheibe geätzt, sandgestrahlt oder beschichtet ausgebildet sein kann.This object is achieved in a multi-pane insulating glass unit of the type mentioned at the outset by providing a light-scattering means between the light exit side of the prismatic plate and the underside of the adjacent glass pane. This light-scattering agent mixes the emerging false radiations of the light components spectrally broken down by the prism plate back into white light. Such a light-scattering means is provided, for example, in the form of the specially machined surface of the adjacent glass pane facing the prism plate, it being possible for the surface of this glass pane to be etched, sandblasted or coated.
Durch die Ätzung bzw. Sandbestrahlung wird die im Normalfalle glatte Oberfläche der Glasscheibe aufgerauht, es entstehen viele kleine Flächenanteile mit zur Ebene der Glasscheibe geneigten Flanken, von welchen die spektral zerlegten Lichtanteile der Fehlstrahlungen aufgefangen und wieder in weisses Licht verwandelt werden.The surface of the glass pane, which is normally smooth, is roughened by the etching or sandblasting, and many small areas are formed with flanks inclined to the plane of the glass pane, from which the spectrally decomposed light components of the false radiation are captured and converted back into white light.
Als lichtstreuendes Mittel kann eine Interferenz-Schicht vorgesehen sein, welche vorteilhaft eine mattierte Folie ist.An interference layer, which is advantageously a matted film, can be provided as the light-scattering means.
Weiter kann das lichtstreuende Mittel ein lichtstreuendes Vlies sein, welches oberhalb der Glasscheibe und unterhalb der Prismenplatte angeordnet wird.Furthermore, the light-scattering agent can be a light-scattering fleece be, which is arranged above the glass pane and below the prismatic plate.
Erfindungsgemäss kann das lichtstreuende Mittel in Form der Ausbil- düng der benachbarten Glasscheibe als Verbundsicherheitsglasscheibe vorgesehen sein, wobei die der Prismenplatte zugekehrte Oberfläche der Verbundsicherheitsglasscheibe wiederum bearbeitet sein kann, also geätzt oder sandgestrahlt ausgeführt ist. Auch kann die Oberfläche der Verbundsicherheitsglasscheibe mit einer Interferenzschicht versehen sein, wobei diese Interferenzschicht in Form einer mattierten Folie zwischen den beiden Einzelscheiben der Verbundsicherheitsglasscheibe angeordnet ist.According to the invention, the light-scattering means can be provided in the form of the formation of the adjacent glass pane as a laminated safety glass pane, the surface of the laminated safety glass pane facing the prism plate in turn being machined, that is to say etched or sandblasted. The surface of the laminated safety glass pane can also be provided with an interference layer, this interference layer being arranged in the form of a matted film between the two individual panes of the laminated safety glass pane.
Eine weitere, erfindungsgemässe Lösung ist die Anordnung eines lichtstreuenden Mittels unmittelbar auf der Oberfläche der Prismen der Prismenplatte.Another solution according to the invention is the arrangement of a light-scattering agent directly on the surface of the prisms of the prism plate.

Die einzelnen Prismen 7 weisen zur Lichtaustritts-Seite hin und können verspiegelt bzw. teilweise verspiegelt ausgebildet sein. Weiter können die Flanken der Prismen je nach Beleuchtungserfordernis unter verschiedenen Winkeln gegenüber der Scheibenebene geneigt sei, wie auch die Winkel zwischen der Laufrichtung der Prismen und des Randes der Glasscheibe unterschiedlich gross sein können.A light-guiding system, for example in the form of a prism plate 6, is fastened between the plane-parallel glass panes 1 and 2 by means not shown in the figures. The individual prisms 7 point to the light exit side and can be mirrored or partially mirrored. Furthermore, depending on the lighting requirements, the flanks of the prisms can be inclined at different angles with respect to the plane of the pane, and the angles between the running direction of the prisms and the edge of the glass pane can be of different sizes.
In einer ersten, in Fig. 1 dargestellten Ausführungsform, ist die der Lichtaustritts-Seite der Prismenplatte 6 zugekehrte Oberfläche 8 der Glasscheibe 2 besonders bearbeitet, d.h., beispielsweise ist die Oberfläche 8 geätzt oder sandgestrahlt ausgeführt oder mit einer Inter ferenzschicht 9 versehen. Eine solche Interferenzschicht 9 kann in Form einer mattierten Folie vorgesehen sein, oder direkt auf die Glasoberfläche aufgebracht sein.In a first embodiment shown in FIG. 1, the surface 8 of the glass pane 2 facing the light exit side of the prism plate 6 is specially processed, ie, for example, the surface 8 is etched or sandblasted or with an interior provided reference layer 9. Such an interference layer 9 can be provided in the form of a matted film or applied directly to the glass surface.
Bei einem weiteren Ausführungsbeispiel der Mehrscheiben-Isolierglas-Einheit gemäss Fig. 2 ist zwischen der Prismenplatte 6 und der Oberfläche 8 der Glasscheibe 2 ein lichtstreuendes Vlies 10 angeordnet, welches den Austritt spektral zerlegter Lichtanteile verhindert.In a further embodiment of the multi-pane insulating glass unit according to FIG. 2, a light-scattering fleece 10 is arranged between the prism plate 6 and the surface 8 of the glass pane 2, which prevents the emission of spectrally split light components.
Bei einem dritten Ausführungsbeispiel der Mehrscheiben-Isolierglas-Einheit gemäss Fig. 3 ist die auf der Lichtaustritts-Seite angeordnete Glasscheibe als Verbundsicherheitsglasscheibe 2' ausgebildet, welche im wesentlichen aus zwei, miteinander verklebten Glasscheiben 11' und 11'' besteht.In a third exemplary embodiment of the multi-pane insulating glass unit according to FIG. 3, the glass pane arranged on the light exit side is designed as a laminated safety glass pane 2 ′, which essentially consists of two glass panes 11 ′ and 11 ″ glued together.

Schliesslich ist es auch möglich, die Oberflächen 13 der Prismen 7 der Prismenplatte 6 bzw. 6' wie die Oberfläche 8 bzw. 8' der Glasscheibe 2 bzw. 2' zu behandeln bzw. mit lichtstreuenden Mitteln aus zustatten, so dass bereits in diesem Bereich die Vermischung der spektral zerlegten Lichtanteile erfolgt, so dass dann auf die zusätzliche Anordnung entsprechender Mittel im Bereich der Glasscheibe 2 bzw. 2' verzichtet werden kann. Finally, it is also possible to treat the surfaces 13 of the prisms 7 of the prism plate 6 or 6 'like the surfaces 8 or 8' of the glass pane 2 or 2 'or with light-scattering agents allow so that the spectrally split light components are already mixed in this area, so that the additional arrangement of corresponding means in the area of the glass pane 2 or 2 'can then be dispensed with.
