Description

Die Erfindung betrifft eine Anordnung zur Erzeugung von Lichteffekten, insbesondere für dekorative Zwecke, mit einer Lichtquelle und einem von der Lichtquelle zu einer Sichtseite hin durchleuchtbaren textilen Flächengebilde. Eine Anordnung zur Erzeugung von Lichteffekten gemäß dem Oberbegriff des Anspruchs 1 ist aus JP-A-2008 040046 bekannt.The invention relates to an arrangement for producing light effects, in particular for decorative purposes, with a light source and a fabric which can be transilluminated from the light source to a visible side. An arrangement for generating light effects according to the preamble of claim 1 is made JP-A-2008 040046 known.

Bekannt sind solche Anordnungen aus Gewebe in Leinwandbindung als Lampenschirm mit dahinter angeordneter Lichtquelle. Bei der Leinwandbindung liegen die verkreuzten Kett- und Schussfäden abwechselnd über- und untereinander. Dabei ist durch die Gewebeöffnungen hindurch die Lichtquelle diffus abgeblendet sichtbar.Such arrangements of plain weave fabric are known as lampshades with light source arranged behind them. In the plain weave, the crossed warp and weft threads are alternately over and under each other. In this case, the light source is visible through the tissue openings diffusely dimmed.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die im Stand der Technik bekannten Anordnungen weiter zu entwickeln und Leuchtobjekte zu schaffen, die neben der Leuchtfunktion und Flächenüberdeckung auch eine besonders ansprechende Gestaltung erlauben.Proceeding from this, the invention has the object to further develop the arrangements known in the prior art and to create luminous objects, which also allow a particularly appealing design in addition to the lighting function and area coverage.

Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem, the feature combination specified in claim 1 is proposed. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Die Erfindung geht von dem Gedanken aus, eine Gitterstruktur möglichst frei von Fadenkrümmungen zur Durchleuchtung zu schaffen. Dementsprechend wird erfindungsgemäß vorgeschlagen, dass das textile Gebilde ein Mehrlagengewebe bzw. eine zweilagige Gewebestruktur aus eine Kettfadenlage bildenden Kettfäden und eine einseitig auf der Kettfadenlage aufliegende Schussfadenlage bildenden Schussfäden aufweist. Das zweilagige Gewebe erlaubt eine parallele Fadenausrichtung in der jeweiligen Fadenlage bei in weiten Grenzen einstellbarer Fadendichte, wobei die Fäden stets an der gleichen (inneren) Fadenhalbseite aufeinanderliegen, so dass eine Ablenkung der auftreffenden Lichtstrahlen zur Sichtseite hin gezielt beeinflussbar ist, um überraschende Lichteffekte in Form eines rückseitigen virtuellen Bildes zu erzielen.The invention is based on the idea of creating a lattice structure as free as possible of thread curvatures for fluoroscopy. Accordingly, it is proposed according to the invention that the textile structure has a multilayer fabric or a two-ply fabric structure comprising warp threads forming a warp thread ply and weft threads forming a weft thread ply resting on the warp thread ply. The two-ply fabric allows a parallel thread alignment in the respective thread layer with adjustable within wide limits thread density, the threads are always on the same (inner) thread half-side, so that a deflection of the incident light rays can be selectively influenced to the visible side to surprising lighting effects in shape to achieve a backside virtual image.

Eine weitere Verbesserung in dieser Hinsicht lässt sich dadurch erreichen, dass die Kettfäden und die Schussfäden im Wesentlichen geradlinig gestreckt sind und jeweils eine gesonderte Ebene aufspannen.A further improvement in this regard can be achieved in that the warp threads and the weft threads are stretched substantially straight and each span a separate plane.

Besonders bevorzugt ist die Fadendichte der Schussfadenlage vorzugsweise um ein Mehrfaches größer als die Fadendichte der Kettfadenlage. Damit kann eine große Fadenfläche zur Lichtablenkung bzw. Reflexion bereitgestellt werden, während zugleich ein hinreichender Öffnungsgrad für den Lichtdurchtritt erreicht wird.Particularly preferably, the thread density of the weft thread layer is preferably greater by a multiple than the thread density of the warp thread layer. Thus, a large thread surface for light deflection or reflection can be provided, while at the same time a sufficient degree of opening for the passage of light is achieved.

In diesem Zusammenhang ist es günstig, wenn der gegenseitige Abstand der Schussfäden von Fadenkante zu Fadenkante im Bereich zwischen 0,05 mm und 1 mm liegt, und dass der Abstand der Kettfäden zueinander, gemessen von Fadenmitte bis Fadenmitte, zwischen 0,6 mm und 10 mm liegt.In this context, it is favorable if the mutual distance of the weft threads from thread edge to thread edge is in the range between 0.05 mm and 1 mm, and that the distance between the warp threads, measured from the middle of the thread to the middle of the thread, between 0.6 mm and 10 mm is located.

Ein weiterer Vorteil hinsichtlich der Gewebestruktur und Reflexionseigenschaften wird dadurch erreicht, dass die Kettfäden und/oder die Schussfäden aus einem vorzugsweise als Monofilament ausgebildeten Filamentgarn gebildet sind. Hierbei ist es günstig, wenn die Kettfäden und/oder die Schussfäden aus einem Polymerwerkstoff wie PET, PA, PP, PTFE, PVDF, PA, PP oder PE oder aus Metall oder mineralischen Fasern wie Glasfasern oder anorganischen Fasern bestehen. Dabei können die Kettfäden und/oder die Schussfäden transparent oder vorzugsweise weiß oder schwarz eingefärbt sein.Another advantage with regard to the fabric structure and reflection properties is achieved in that the warp threads and / or the weft threads are formed from a filament yarn, which is preferably designed as a monofilament. In this case, it is favorable if the warp threads and / or the weft threads consist of a polymer material such as PET, PA, PP, PTFE, PVDF, PA, PP or PE or of metal or mineral fibers such as glass fibers or inorganic fibers. In this case, the warp threads and / or the weft threads can be colored transparent or preferably white or black.

Vorteilhafterweise besitzen die Kettfäden und die als Endlosgarn ausgebildeten Schussfäden einen Durchmesser im Bereich zwischen 0,08 mm und 1 mm. Möglich ist es auch, solche Schussfäden in Kombination mit einem Spinnfasergarn einzutragen.Advantageously, the warp threads and the weft threads designed as endless yarn have a diameter in the range between 0.08 mm and 1 mm. It is also possible to enter such weft threads in combination with a spun yarn.

Die zweilagige Gewebestruktur lässt sich auf vorteilhafte Weise dadurch fixieren, dass die Kettfäden und die Schussfäden durch Bindefäden miteinander verbunden sind, wobei die Bindefäden die voneinander abgewandten Außenseiten der Kett- und Schussfäden umschlingen.The two-ply fabric structure can be advantageously fixed in that the warp threads and the weft threads are connected to each other by binding threads, wherein the binding threads wrap around the outer sides of the warp and weft threads facing away from each other.

Hierbei ist es von Vorteil, wenn die Bindefäden als Mono- oder Multifilamente auf Polymerbasis insbesondere aus PET, PA, PP, PTFE, PVDF, PA, PP oder PE gebildet sind und einen Durchmesser von weniger als 0,1 mm besitzen.It is advantageous if the binding threads are formed as mono- or multifilaments on a polymer basis, in particular of PET, PA, PP, PTFE, PVDF, PA, PP or PE and have a diameter of less than 0.1 mm.

Zur Erzielung besonders prägnanter Lichteffekte sollte die Lichtquelle aus einer oder mehreren punkt- oder linienförmigen Einzel-Lichtquellen, vorzugsweise LEDs gebildet sein. Dabei können die Einzel-Lichtquellen linienförmig, flächig oder räumlich verteilt angeordnet sein.To achieve particularly incisive lighting effects, the light source should be formed from one or more point or line-shaped individual light sources, preferably LEDs. In this case, the individual light sources can be arranged distributed linear, planar or spatially.

Um die Lichteffekte besonders auszuprägen, sollte die Lichtquelle im Abstand von mindestens 5 mm zu der von der Sichtseite abgewandten Rückseite des textilen Flächengebildes angeordnet sein.In order to emphasize the light effects in particular, the light source should be arranged at a distance of at least 5 mm to the side facing away from the visible side of the back of the textile fabric.

Zur vereinfachten Installation ist es vorteilhaft, wenn das textile Flächengebilde in einer Halterung eben aufgespannt oder räumlich gekrümmt gehalten ist.For simplified installation, it is advantageous if the textile fabric is just clamped in a holder or held spatially curved.

Eine weitere Effektverstärkung lässt sich dadurch erreichen, dass das textile Flächengebilde mehrere hintereinander durchleuchtete Gewebeflächen aufweist.A further effect enhancement can be achieved in that the textile fabric has a plurality of tissue surfaces which are illuminated in succession.

Vorteilhafterweise wird das Licht der Lichtquelle im Wesentlichen durch die zueinander parallelen Fäden in den beiden Fadenlagen zur Erzeugung eines Lichteffekts abgelenkt. Solche Effekte lassen sich dadurch erzeugen, dass das textile Flächengebilde als optische Einheit im Strahlengang ein von der Sichtseite her beobachtbares virtuelles Bild der Lichtquelle erzeugt.Advantageously, the light of the light source is deflected substantially by the mutually parallel threads in the two layers of thread to produce a light effect. Such effects can be created by the textile fabric, as an optical unit in the beam path, generates a virtual image of the light source observable from the visible side.

Im Folgenden wird die Erfindung anhand der in der Zeichnung in schematischer Weise dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:

In the following the invention will be explained in more detail with reference to the embodiments schematically illustrated in the drawing. Show it:

Die in der Zeichnung dargestellte Leuchtanordnung ermöglicht die Erzeugung von Lichteffekten, die neben einer Beleuchtungsfunktion auch dekorative Zwecke erfüllen können. Die Anordnung umfasst eine Lichtquelle 10 und ein textiles Flächengebilde 12, das von dem Licht 14 der Lichtquelle 10 zu einer Sichtseite 16 hin durchleuchtbar ist. Bei sichtseitiger Betrachtung ergibt sich ein virtuelles Bild der Lichtquelle 10 in dem von der Sichtseite abgewandten rückseitigen Raum.The light assembly shown in the drawing allows the generation of light effects that can also fulfill decorative purposes in addition to a lighting function. The arrangement comprises a light source 10 and a textile fabric 12 which can be transilluminated by the light 14 of the light source 10 towards a visible side 16. When viewed from the perspective results a virtual image of the light source 10 in the rear side facing away from the visible side.

Zur Erzeugung eines solchen Effekts besteht das textile Flächengebilde 12 als zweidimensional ausgedehntes, ebenes oder gekrümmtes Gewebe aus einer zweilagigen Gitterstruktur. Diese wird gemäß Fig. 1 aus rechtwinklig verkreuzten Kettfäden 18 und Schussfäden 20 gebildet. Die Grundfäden 18, 20 werden dabei durch dünne Bindefäden 22 ähnlich einer Dreherbindung gegenseitig fixiert. Der besseren Übersichtlichkeit halber ist die Fadenanordnung in Fig. 1 nicht maßstabsgerecht gezeigt.To produce such an effect, the textile fabric 12 is a two-dimensionally extended, planar or curved fabric of a two-layered lattice structure. This is according to Fig. 1 formed from rectangular intersected warp threads 18 and weft threads 20. The ground threads 18, 20 are thereby fixed to each other by thin binding threads 22 similar to a leno weave. For better clarity, the thread arrangement in Fig. 1 not shown to scale.

Wie sich auch aus Fig. 2 und 3 ergibt, bilden die Kettfäden 18 eine ebene Kettfadenlage 26 und die Schussfäden 20 eine davon gesonderte, ebene bzw. flächig getrennte Schussfadenlage 24. Um dies zu erreichen, sind die Kettfäden 18 und Schussfäden 20 im Wesentlichen geradlinig gestreckt angeordnet, so dass sich die Fadenlagen gegenseitig nicht durchdringen. Die Grundfäden 18, 20 berühren sich somit immer an der gleichen (inneren) Fadenhalbseite, während die Bindefäden 22 die voneinander angewandten Außenseiten der Grundfäden 18, 20 umschlingen. Gegebenenfalls können die Kreuzungspunkte noch zusätzlich durch Klebstoff fixiert werden.As it turned out FIGS. 2 and 3 The warp threads 18 form a flat warp thread layer 26 and the weft threads 20 form a separate, flat or flat weft thread layer 24. In order to achieve this, the warp threads 18 and weft threads 20 are stretched substantially in a straight line so that the thread layers are mutually aligned do not penetrate. The ground threads 18, 20 thus always touch each other on the same (inner) thread half-side, while the binding threads 22 wrap around the outer sides of the ground threads 18, 20 which are used from one another. Optionally, the crossing points can be additionally fixed by adhesive.

Um besondere Lichteffekte zu erzeugen, liegen die Schussfäden 20 zweckmäßig um ein Mehrfaches dichter als die Kettfäden 18. Beispielsweise kann der gegenseitige Abstand der Schussfäden von Fadenkante zu Fadenkante im Bereich zwischen 0,05 mm und 1 mm liegen, während der Abstand der Kettfäden zueinander, gemessen von Fadenmitte bis Fadenmitte, zwischen 0,6 mm und 10 mm liegt. Die Kett- und Schussfäden 18, 20 sollten dabei einen Durchmesser im Bereich zwischen 0,08 mm und 1 mm besitzen und bevorzugt als Monofilamente ausgebildet sein. Die Bindefäden 22 können als Mono- oder Multifilamente auf Polymerbasis einen Durchmesser von weniger als 0,1 mm besitzen.To produce special lighting effects, the weft threads 20 are expediently a multiple denser As the warp threads 18. For example, the mutual distance of the weft threads from thread edge to thread edge in the range between 0.05 mm and 1 mm, while the distance between the warp threads, measured from the middle of the thread to center of the thread, between 0.6 mm and 10 mm , The warp and weft threads 18, 20 should have a diameter in the range between 0.08 mm and 1 mm and preferably be formed as monofilaments. The binder yarns 22 may be less than 0.1 mm in diameter as a polymer-based monofilament or multifilament.

Als Fadenmaterial für die Grundfäden 18, 20 ist ebenfalls ein Polymerwerkstoff wie PET, PA, PP, PTFE, PVDF, PA, PP oder PE geeignet. Alternativ ist auch der Einsatz von Metallfäden, Glasfäden oder Fäden aus anorganischen Materialien denkbar. Das Fadenmaterial kann transparent sein oder eingefärbt sein. Bevorzugt bestehen die Schussfäden aus einem Endlosgarn und werden gegebenenfalls in Kombination mit einem Spinnfasergarn eingetragen. In der Kette sind auch Kombinationen mit Fasergarnen denkbar. Zur Erzielung spezifischer Eigenschaften, wie z.B. Flammschutz, kann das Gewebe auch ausgerüstet werden.As a thread material for the ground yarns 18, 20 is also a polymer material such as PET, PA, PP, PTFE, PVDF, PA, PP or PE suitable. Alternatively, the use of metal threads, glass threads or threads of inorganic materials is conceivable. The thread material may be transparent or colored. Preferably, the weft threads consist of an endless yarn and are optionally added in combination with a spun yarn. In the chain also combinations with fiber yarns are conceivable. To achieve specific properties, e.g. Flame arrest, the fabric can also be equipped.

Das textile Flächengebilde 12 kann in einer Halterung, beispielsweise einem Rahmen 28 aufgespannt sein. Die Lichtquelle 10 kann dabei an dem Rahmen 28 befestigt sein oder beispielsweise an einer Zimmerdecke oder Wand gesondert montiert sein. Dabei sollte gewährleistet sein, dass die Lichtquelle 10 einen rückseitigen Abstand von dem Flächengebilde 12 in Richtung der Flächennormalen gesehen von mindestens 5 mm aufweist, um die Lichteffekte besonders zur Geltung zu bringen. Hierfür ist es ebenfalls günstig, wenn die Lichtquelle 10 als Punktlichtquelle ausgebildet ist.The textile fabric 12 may be clamped in a holder, for example a frame 28. The light source 10 may be attached to the frame 28 or be mounted separately, for example, on a ceiling or wall. It should be ensured be that the light source 10 has a rear-side distance from the sheet 12 in the direction of the surface normal seen at least 5 mm in order to bring the lighting effects particularly to advantage. For this purpose, it is also advantageous if the light source 10 is formed as a point light source.

Wie in dem Beispiel gemäß Fig. 4 und 5 gezeigt, kann die Lichtquelle 10 eine Vielzahl von Einzel-Lichtquellen 30 aufweisen, die vorzugsweise als Leuchtdioden jeweils eine Punktlichtquelle bilden. Die Einzel-Lichtquellen 30 können linienförmig (Fig. 4) oder flächig verteilt (Fig. 5) in einer parallel zu dem textilen Flächengebilde 12 verlaufenden Gegenstandsebene angeordnet sein. Denkbar ist aber auch ein variierender Abstand oder eine bezüglich des Flächengebildes 12 geneigte Anordnung. Der Einsatz von RGB-LEDs ermöglicht eine Farbsteuerung der Lichteffekte. Komplexe Lichteffekte lassen sich auch dadurch erzeugen, dass als textiles Flächengebilde mehrere Mehrlagengewebe hintereinander angeordnet und gemeinsam durchstrahlt werden.As in the example according to 4 and 5 As shown, the light source 10 may comprise a plurality of individual light sources 30, which preferably each form a point light source as light emitting diodes. The individual light sources 30 can be linear ( Fig. 4 ) or distributed over a large area ( Fig. 5 ) may be arranged in an object plane extending parallel to the textile fabric 12. It is also conceivable, however, a varying distance or with respect to the sheet 12 inclined arrangement. The use of RGB LEDs allows a color control of the lighting effects. Complex light effects can also be produced by arranging several multi-layer fabrics one behind the other as a textile fabric and irradiating them together.

Fig. 6 veranschaulicht die Erzeugung eines Lichteffekts durch das textile Flächengebilde im Strahlengang der Lichtquelle 10. Dabei werden von der Lichtquelle 10 ausgehende Lichtstrahlen 14 durch den zylindrischen Mantel 32 der parallelen Grundfäden 18, 20 abgelenkt. Die dicht liegenden Schussfäden 20 bilden dabei die hauptsächliche Reflexionsfläche, welche die Strahlen 14 in das Auge 34 eines Betrachters reflektiert. In der Rückwärtsverlängerung 36 ergibt sich dann ein virtuelles Bild 38, das für den Betrachter rückseitig von dem Flächengebilde 12 erscheint. Je nach Fadenlage und -dichte entstehen punkt- oder linienförmige oder gitterförmige Bildeffekte, die je nach Lichtquellenanordnung und -ausrichtung sowie Beobachterstandort bzw. Beobachtungswinkel variieren. Dabei können die Kettfäden 18 oder die Schussfäden 20 auf der Sichtseite 16 des Flächengebildes 12 angeordnet sein. Fig. 6 illustrates the generation of a light effect by the fabric in the beam path of the light source 10. In this case, emanating from the light source 10 light beams 14 are deflected by the cylindrical shell 32 of the parallel ground yarns 18, 20. The tight weft threads 20 form the main reflection surface, which the rays 14 reflected in the eye 34 of a viewer. In the backward extension 36 then results in a virtual image 38, which appears to the viewer back of the fabric 12. Depending on the thread position and density, dot-like or linear or latticed image effects occur, which vary depending on the light source arrangement and orientation as well as the observer location or viewing angle. In this case, the warp threads 18 or the weft threads 20 can be arranged on the visible side 16 of the fabric 12.

Die eingesetzten Filamentgarne (vorzugsweise Monofilamente) bieten gute Reflektionsoberflächen, so dass das Licht kaum gestreut wird. Ferner zeichnet sich das textile Flächengebilde 12 aufgrund des Lagenaufbaus und der gestreckten Grundfäden 18, 20 dadurch aus, dass die guten Reflektionseigenschaften des Fadenmaterials erhalten bleiben und dass ausreichend freie Fadenoberfläche als Reflektionsfläche zur Verfügung steht. Ferner hat das Gewebe aufgrund der gestreckten Fadenlage und der unterschiedlichen Fadendichten der Schuss- und der Kettlage ausreichend große Öffnungen, durch die das reflektierte Licht auf den Betrachter fallen kann.The filament yarns used (preferably monofilaments) provide good reflection surfaces, so that the light is hardly scattered. Furthermore, the textile fabric 12 is characterized by the layer structure and the elongated base threads 18, 20 in that the good reflection properties of the thread material are retained and that sufficient free thread surface is available as a reflection surface. Furthermore, due to the stretched yarn layer and the different thread densities of the weft and warp layers, the fabric has sufficiently large openings through which the reflected light can fall on the viewer.

Grundsätzlich wird das einfallende Licht an beiden Fadenlagen 24, 26 reflektiert. Jede Fadenlage erzeugt einen Lichteffekt senkrecht zur Fadenachse. Die Intensität des erzeugten Lichteffektes hängt von der Anzahl der Reflexionsflächen ab. Aufgrund der höheren Schussfadendichte ist auch das durch die Schussfadendichte ist auch das durch die Schussfadenlage 24 erzeugte virtuelle Bild dichter und besitzt eine höhere Lichtintensität. Das durch die Kettfadenlage 26 erzeugte virtuelle Bild kann so weit überlagert werden, dass es vom Betrachter nicht mehr wahrgenommen wird. Die reine Reflexion an der Oberfläche 32 kann je nach Fadenmaterial durch Brechung überlagert werden. Ferner kann es aufgrund der geringen Fadenabstände in Schussrichtung auch zu Beugungen am Spalt kommen.In principle, the incident light is reflected at both thread layers 24, 26. Each thread layer produces a light effect perpendicular to the thread axis. The intensity of the generated light effect depends on the number of reflective surfaces. Due to the higher weft density is also due to the weft density Also, the virtual image formed by the weft layer 24 is denser and has a higher light intensity. The virtual image generated by the warp layer 26 can be superimposed so far that it is no longer perceived by the viewer. The pure reflection on the surface 32 can be superimposed by refraction depending on the thread material. Furthermore, it may also come to diffraction at the gap due to the small thread intervals in the weft direction.

Eine weitere vorteilhafte Einsatzmöglichkeit des textilen Flächengebildes 12 besteht in der Nutzung als Projektionsfläche für einen Projektor beispielsweise einen Beamer. In diesem Fall sollten die dicht liegenden Schussfäden 20 dem Projektor zugewandt sein. Auf diese Weise lässt sich eine Doppelfunktion erreichen, indem die Projektionsfläche bei Nichtgebrauch durch die Hinterleuchtung mit der Lichtquelle 10 gestalterisch einsetzbar ist.Another advantageous use of the textile fabric 12 is the use as a projection surface for a projector, for example, a projector. In this case, the tight weft yarns 20 should face the projector. In this way, a dual function can be achieved by the projection surface when not in use by the backlight with the light source 10 is creatively applicable.
