Description

PANNEAU LUMINEUX ET SON PROCEDE DE FABRICATIONLUMINOUS PANEL AND METHOD FOR MANUFACTURING THE SAME
La présente invention se rapporte à un panneau lumineux et à son procédé de fabrication.The present invention relates to a light panel and its manufacturing method.
En particulier, la présente invention se rapporte à un panneau lumineux destiné à un usage décoratif. Par exemple, le panneau peut être intégré dans du mobilier.In particular, the present invention relates to a light panel for decorative use. For example, the panel can be integrated into furniture.
Dans le cadre de la présente description, « panneau lumineux » signifie que le panneau est apte à transmettre de la lumière depuis une source de lumière vers une face extérieure du panneau.In the context of the present description, "light panel" means that the panel is able to transmit light from a light source to an outer face of the panel.
Les documents WO 2008/043975 et WO 2008/035010 décrivent des panneaux lumineux comprenant une nappe de fibres optiques disposée parallèlement à la face extérieure du panneau. Dans certains modes de réalisation, le panneau comprend un écran protecteur extérieur en matériau transparent. Pour réaliser un motif d'éclairage particulier, il est nécessaire soit d'utiliser un masque, soit de prévoir une disposition particulière des fibres optiques de la nappe. Le document WO 2008/031610 décrit un panneau lumineux dans lequel des fibres optiques traversent l'épaisseur du panneau pour transmettre la lumière. Les fibres optiques peuvent être disposées de manière à réaliser un motif d'éclairage désiré. Cependant, ce panneau ne peut être réalisé qu'en béton ou avec un autre matériau apte à être moulé. Or, dans le domaine de la décoration d'intérieur, on souhaite utiliser d'autre matériau, notamment pour des raisons de poids, résistance mécanique, aspect esthétique, coût par exemple.WO 2008/043975 and WO 2008/035010 disclose light panels comprising an optical fiber ply disposed parallel to the outer face of the panel. In some embodiments, the panel includes an outer protective shield of transparent material. To achieve a particular lighting pattern, it is necessary either to use a mask, or to provide a particular arrangement of the optical fibers of the web. WO 2008/031610 discloses a light panel in which optical fibers pass through the thickness of the panel to transmit light. The optical fibers may be arranged to achieve a desired lighting pattern. However, this panel can be made in concrete or other material capable of being molded. However, in the field of interior decoration, it is desired to use other material, especially for reasons of weight, mechanical strength, aesthetic appearance, cost for example.
Un problème que la présente invention propose de résoudre est de fournir un panneau lumineux qui ne présente pas au moins certains des inconvénients précités de l'art antérieur.A problem that the present invention proposes to solve is to provide a light panel that does not exhibit at least some of the aforementioned drawbacks of the prior art.
En particulier, la présente invention a pour but de fournir un panneau lumineux dans lequel le matériau peut être choisi plus librement. Un autre but de l'invention est de pouvoir réaliser facilement un motif d'éclairage particulier. La solution proposée par l'invention est un panneau lumineux, comprenant une couche extérieure traversée par des fibres optiques dans le sens de l'épaisseur, caractérisé par le fait que ladite couche extérieure comprend une pluralité de lamelles juxtaposées, lesdites fibres optiques passant entre au moins deux desdites lamelles adjacentes.In particular, the present invention aims to provide a light panel in which the material can be chosen more freely. Another object of the invention is to easily achieve a particular lighting pattern. The solution proposed by the invention is a light panel, comprising an outer layer traversed by optical fibers in the direction of the thickness, characterized in that said outer layer comprises a plurality of juxtaposed strips, said optical fibers passing between minus two of said adjacent lamellae.
Grâce à ces caractéristiques, les lamelles de la couche extérieure ne doivent pas nécessairement être réalisées en un matériau apte à être moulé. On peut choisir le matériau en fonction de critères tels que le coût, le poids, l'aspect esthétique par exemple. De plus, la forme des lamelles, entre lesquels sont disposées les fibres optiques, permet de définir des motifs d'éclairages particuliers, par exemples des lignes parallèles parfaitement droites.Thanks to these characteristics, the lamellae of the outer layer need not necessarily be made of a material that can be molded. We can choose the material according to criteria such as cost, weight, aesthetic appearance for example. In addition, the shape of the lamellae, between which the optical fibers are arranged, makes it possible to define particular lighting patterns, for example parallel lines that are perfectly straight.
De préférence, les lamelles sont en bois.Preferably, the slats are wood.
Selon un mode de réalisation particulier, le panneau lumineux comprend une nappe de fibres optiques adjacente à ladite couche extérieure.According to a particular embodiment, the light panel comprises a sheet of optical fibers adjacent to said outer layer.
Avantageusement, le panneau lumineux comprend un support rigide adjacent à ladite nappe, du côté opposé à ladite couche extérieure.Advantageously, the light panel comprises a rigid support adjacent to said sheet, on the opposite side to said outer layer.
De préférence, le support rigide, ladite nappe et lesdites lamelles sont reliés par une résine.Preferably, the rigid support, said sheet and said strips are connected by a resin.
Selon un mode de réalisation particulier, ladite nappe est reliée à une source de lumière.According to a particular embodiment, said sheet is connected to a light source.
L'invention fournit également un procédé de fabrication d'un panneau lumineux selon l'invention ci-dessus, comprenant : - la découpe d'un tissu de fibre optique en plusieurs portions,The invention also provides a method of manufacturing a light panel according to the invention above, comprising: - cutting an optical fiber fabric in several portions,
- l'utilisation d'une desdites portions pour réaliser ladite nappe,the use of one of said portions to produce said sheet,
- l'utilisation d'une autre desdites portions dans ladite couche extérieure.the use of another of said portions in said outer layer.
Grâce à ces caractéristiques, il n'est pas nécessaire de disposer de deux sources de fibres optiques.Thanks to these characteristics, it is not necessary to have two sources of optical fibers.
L'invention sera mieux comprise, et d'autres buts, détails, caractéristiques et avantages de celle-ci apparaîtront plus clairement au cours de la description suivante d'un mode de réalisation particulier de l'invention, donné uniquement à titre illustratif et non limitatif, en référence aux dessins annexés. Sur ces dessins : - la figure 1 est une vue de face d'un panneau lumineux selon un mode de réalisation de l'invention,The invention will be better understood, and other objects, details, features and advantages thereof will appear more clearly in the following description of a particular embodiment of the invention, given solely for illustrative purposes and not limiting, with reference to the accompanying drawings. On these drawings: FIG. 1 is a front view of a light panel according to one embodiment of the invention,
- la figure 2 est une vue en coupe du panneau de la figure 1.- Figure 2 is a sectional view of the panel of Figure 1.
Le panneau lumineux 1 représenté sur les figures 1 et 2 comprend une couche extérieure 2, un support rigide 6, et une nappe 5 agencée entre la couche extérieure 2 et le support rigide 6.The light panel 1 shown in FIGS. 1 and 2 comprises an outer layer 2, a rigid support 6, and a sheet 5 arranged between the outer layer 2 and the rigid support 6.
La nappe 5 comprend des fibres optiques et des fils de liage, par exemple de manière similaire à la nappe qui est décrite dans le document WO 2008/035010 cité en introduction. Les fibres optiques de la nappe 5 sont reliées à une source de lumière non représentée, ce qui permet de diffuser de la lumière entre la couche extérieure 2 et le support rigide 6. Le support rigide 6 est par exemple réalisé en bois. La couche extérieure 2 comprend une pluralité de lamelles 3 parallélépipédiques, disposées parallèlement les unes aux autres. Les lamelles 3 sont réalisées par exemple en bois. La couche extérieure 2 comprend également des fibres optiques 4.The web 5 comprises optical fibers and binding yarns, for example in a manner similar to the web which is described in the document WO 2008/035010 cited in the introduction. The optical fibers of the sheet 5 are connected to a source of light, not shown, which makes it possible to diffuse light between the outer layer 2 and the rigid support 6. The rigid support 6 is for example made of wood. The outer layer 2 comprises a plurality of parallelepipedal slats 3, arranged parallel to each other. The slats 3 are made for example of wood. The outer layer 2 also comprises optical fibers 4.
Comme on peut le voir sur les figures 1 et 2, les fibres optiques 4 sont disposées entres les lamelles 3, et s'étendent dans le sens de l'épaisseur de la couche extérieure 2, donc perpendiculairement à la face extérieure 7 de la couche extérieure 2. Plus précisément, chaque fibre optique 4 comprend une extrémité adjacente à la nappe 5 et une extrémité qui affleure au niveau de la face extérieure 7 de la couche extérieure 2. Ainsi, lorsque la nappe 5 diffuse de la lumière entre le support rigide 6 et la couche extérieure 2, les fibres optiques 4 transmettent la lumière depuis la nappe 5 vers la face extérieure 7. On voit donc apparaître des lignes lumineuses sur la face extérieure 7.As can be seen in FIGS. 1 and 2, the optical fibers 4 are arranged between the strips 3 and extend in the direction of the thickness of the outer layer 2, thus perpendicular to the outer face 7 of the layer 2. More specifically, each optical fiber 4 comprises an end adjacent to the sheet 5 and an end flush with the outer face 7 of the outer layer 2. Thus, when the sheet 5 diffuses light between the rigid support 6 and the outer layer 2, the optical fibers 4 transmit light from the sheet 5 to the outer face 7. Thus light lines appear on the outer face 7.
Les fibres optiques 4 sont reliées entre elles par des fils de liage. Lors de la fabrication du panneau lumineux 1, on peut utiliser le même tissu, comprenant des fibres optiques et des fils de liage, pour réaliser la nappe 5 et les fibres optiques 4.The optical fibers 4 are interconnected by binding wires. During the manufacture of the light panel 1, it is possible to use the same fabric, comprising optical fibers and binding wires, to produce the sheet 5 and the optical fibers 4.
Les lamelles 3, les fibres optiques 4, la nappe 5 et le support rigide 6 sont reliés les uns aux autres par de la résine. Dans d'autres modes de réalisations non représentés, les lamelles présentent d'autres formes ou sont agencées différemment que sur la figure 1. Dans ce cas, le panneau lumineux présente un motif d'éclairage différent des lignes droites parallèles.The strips 3, the optical fibers 4, the sheet 5 and the rigid support 6 are connected to each other by resin. In other embodiments not shown, the slats have other shapes or are arranged differently than on the In this case, the light panel has a lighting pattern different from the parallel straight lines.
Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention. Although the invention has been described in connection with a particular embodiment, it is obvious that it is not limited thereto and that it comprises all the technical equivalents of the means described and their combinations if they are within the scope of the invention.
