Description

COMPLEXE ECLAIRANT VERRIER VERRIER LIGHTING COMPLEX
DOMAINE DE L'INVENTIONFIELD OF THE INVENTION
L'invention se rapporte au domaine de l'éclairage d'une structure transparente ou semi-transparente.The invention relates to the field of lighting a transparent or semi-transparent structure.
L'invention vise plus particulièrement le type et le mode d'intégration de la source lumineuse à l'intérieur du complexe éclairant verrier comportant au moins deux couches en verre.The invention relates more particularly to the type and mode of integration of the light source within the illuminating glass complex comprising at least two glass layers.
ETAT ANTÉRIEURDE LA TECHNIQUEPRIOR STATE OF THE ART
De façon générale, les complexes éclairants présentant une structure transparente peuvent se présenter de diverses manières et générer des éclairages diffus ou ponctuels sur l'ensemble de leur surface.In general, illuminating complexes presenting a transparent structure can be presented in various ways and generate diffuse or point-like lighting on their entire surface.
Les complexes éclairants permettant de réaliser une lumière sur toute leur surface comportent des sources de lumière agencées en lisière d'une plaque translucide de verre ou de polyméthacrylate de méthyle (PMMA). Ces plaques comprennent sur une de leurs faces un motif gravé permettant de générer des arêtes vives aptes à dévier la lumière dans une direction donnée.The illuminating complexes making it possible to provide light over their entire surface comprise light sources arranged on the edge of a translucent plate of glass or of polymethylmethacrylate (PMMA). These plates comprise on one of their faces an engraved pattern for generating sharp edges capable of deflecting the light in a given direction.
De tels complexes sont notamment utilisés pour rétroéclairer différents supports et notamment des clichés réalisés sur une feuille transparente telle qu'utilisée pour les clichés radiologiques. Des sources lumineuses sont agencées à la périphérie de la plaque gravée, et permettent d'émettre de la lumière à l'intérieur du volume défini par la plaque.Such complexes are used in particular to backlight various media including shots made on a transparent sheet as used for X-rays. Light sources are arranged at the periphery of the etched plate, and allow light to be emitted within the volume defined by the plate.
Cependant, un tel complexe présente des gravures disgracieuses visibles et donc néfastes à l'homogénéité de la source lumineuse. Ces gravures restent également visibles lorsque le complexe n'est pas éclairé, ce qui ne permet pas de rendre totalement invisible la source lumineuse à l'intérieur du complexe éclairant.However, such a complex has unsightly etchings visible and therefore detrimental to the homogeneity of the light source. These engravings also remain visible when the complex is not lit, which does not make the light source completely invisible inside the illuminating complex.
Selon un autre mode de réalisation, on connaît également des complexes éclairants rapportés à la surface d'une plaque transparente de manière à former un complexe éclairant verrier à éclairage ponctuel. Dans ce cas, des diodes électroluminescentes (LED) sont positionnées entre deux plaques de verre. Par ailleurs, un circuit électronique transparent est agencé également entre les deux plaques de verre de manière à alimenter en énergie électrique les différentes diodes électroluminescentes. Cependant, un tel complexe éclairant ne permet pas de réaliser un éclairage diffus de la surface vitrée. De plus, son coût de fabrication est sensiblement élevé puisqu'il faut disposer manuellement et indépendamment chaque source ponctuelle dans une zone particulière de la surface vitrée.According to another embodiment, illuminating complexes are also reported on the surface of a transparent plate so as to form a lighting complex lighting punctual lighting. In this case, light-emitting diodes (LEDs) are positioned between two glass plates. Furthermore, a transparent electronic circuit is also arranged between the two glass plates so as to supply the various electroluminescent diodes with electrical energy. However, such an illuminating complex does not allow to achieve diffuse illumination of the glass surface. In addition, its manufacturing cost is substantially high since it is necessary to manually and independently dispose each point source in a particular area of the glass surface.
Ainsi, le but de l'invention est de réaliser un éclairage diffus d'une plaque transparente ou translucide en verre, celle-ci pouvant être totalement invisible à l'intérieur du volume défini par la plaque.Thus, the object of the invention is to achieve a diffuse illumination of a transparent or translucent glass plate, it can be completely invisible within the volume defined by the plate.
Par ailleurs, un autre objectif de l'invention est de réaliser un éclairage homogène avec une puissance d'éclairage supérieure à celle des produits existants.Furthermore, another object of the invention is to achieve homogeneous illumination with a lighting power greater than that of existing products.
On connaît également des complexes éclairants formés par un textile comportant des fibres optiques aptes à transmettre latéralement de la lumière, ce textile étant associé à une couche de résine époxy pour diffuser la lumière. Un tel complexe éclairant, notamment décrit dans le document US 5 021 928, présentent cependant de nombreux inconvénients.Also known are illuminating complexes formed by a textile comprising optical fibers capable of transmitting light laterally, this textile being associated with an epoxy resin layer for diffusing light. Such an illuminating complex, in particular described in US Pat. No. 5,021,928, however, has numerous disadvantages.
En effet, la résistance à la chaleur et à la flamme d'un tel complexe n'est pas optimale ou non compatible avec la transparence du complexe éclairant. Ainsi, même s'il existe certaines résines adaptées pour résister au feu, elles ne présentent pas une transparence parfaite.Indeed, the resistance to heat and flame of such a complex is not optimal or not compatible with the transparency of the illuminating complex. Thus, even if there are some resins adapted to resist fire, they do not have perfect transparency.
De plus, la fabrication de ce type de complexe éclairant impose un procédé de fabrication très long à mettre en œuvre, et plus particulièrement s'il est réalisé sur les deux faces du textile.In addition, the manufacture of this type of illuminating complex requires a very long manufacturing process to implement, especially if it is performed on both sides of the textile.
Un troisième objectif de l'invention est donc de réaliser un complexe éclairant à la fois résistance à la chaleur et à la flamme tout en étant totalement transparent. Enfin son procédé de fabrication doit être simple et rapide à réaliser.A third object of the invention is therefore to provide an illuminating complex with both heat and flame resistance while being completely transparent. Finally, its manufacturing process must be simple and quick to perform.
EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION
L'invention concerne donc un complexe éclairant comportant deux couches en verre présentant une surface éclairante transparente ou translucide.The invention therefore relates to an illuminating complex comprising two glass layers having a transparent or translucent illuminating surface.
Selon l'invention, il se caractérise en ce qu'il comporte une source lumineuse présentant une nappe textile intégrant des fibres optiques en chaîne et/ou en trame associées avec des fils de liage en chaîne et en trame. De telles fibres optiques sont aptes à émettre latéralement la lumière. Par ailleurs, la nappe textile est noyée entre les deux couches.According to the invention, it is characterized in that it comprises a light source having a textile web incorporating optical fibers in warp and / or weft associated with warp and weft son of warp. Such optical fibers are able to emit light laterally. Moreover, the textile web is embedded between the two layers.
Autrement dit, la nappe textile comporte des fibres optiques permettant à la fois de véhiculer la lumière à l'intérieur de leur structure, mais également d'émettre latéralement la lumière à l'intérieur du complexe éclairant verrier apte à en illuminer de manière diffuse la surface définie par le complexe. Une telle nappe textile éclairante peut être réalisée de diverses manières, et notamment en procédant à une attaque invasive de la gaine des fibres optiques.In other words, the textile web comprises optical fibers making it possible both to convey the light inside their structure, but also to emit light laterally inside the illuminating glass complex capable of diffusely illuminating it. area defined by the complex. Such an illuminating textile ply can be made in various ways, and in particular by performing an invasive attack on the sheath of the optical fibers.
Cette attaque génère alors des altérations qui peuvent être obtenue par exemple par un procédé de sablage de la nappe textile, une attaque chimique ou au moyen d'un rayon lumineux de très forte intensité balayant la surface de la nappe textile. Ce traitement de la nappe textile peut être réalisé sur toute sa surface pour rendre totalement éclairant le complexe verrier. Il peut également être localisé et décrire un motif particulier pour réaliser une signalisation, afficher un message ou encore une image.This attack then generates alterations that can be obtained for example by a sanding process of the textile web, a chemical attack or by means of a very high intensity light beam scanning the surface of the textile web. This treatment of the textile web can be performed on its entire surface to make fully illuminating the glass complex. It can also be located and describe a particular pattern to carry out a signaling, display a message or an image.
Par ailleurs, le complexe verrier peut être utilisé comme une cloison de séparation entre deux volumes. Par ailleurs, ses deux faces en verre sont aptes à protéger la nappe textile d'éventuelles agressions extérieures pouvant engendrer sa détérioration. Un tel complexe éclairant verrier peut être obtenu selon les procédés classiques de réalisation d'un verre feuilleté présentant un empilement de plusieurs feuilles de verre, de films ou de résines.In addition, the glass complex can be used as a separation wall between two volumes. Moreover, its two glass faces are able to protect the textile web from possible external aggression that can cause its deterioration. Such an illuminating glass complex may be obtained according to conventional methods of producing a laminated glass having a stack of several sheets of glass, films or resins.
En pratique, les fibres optiques agencées en chaîne et/ou en trame sont tissées avec les fils de liage. De cette manière, la nappe textile présente une tenue naturelle, ce qui permet une manipulation aisée pour procéder notamment à sa mise en place dans le complexe verrier, mais aussi pour diverses fonctions annexes comme la connexion des fibres optiques avec une source de lumière. Différentes armures de tissage peuvent être utilisées, et en particulier l'armure toile qui permet d'assurer une bonne transmission de la lumière dans les deux directions normales au tissu.In practice, the optical fibers arranged in warp and / or weft are woven with the binding threads. In this way, the textile web has a natural hold, which allows easy handling to proceed including its implementation in the glass complex, but also for various auxiliary functions such as the connection of optical fibers with a light source. Different weave armor can be used, and in particular plain weave which ensures good light transmission in both directions normal to the fabric.
Ainsi, selon un premier mode de réalisation, au moins une couche du complexe verrier comprend une feuille de verre et une résine interposée entre la nappe textile et la feuille de verre. En d'autres termes, la liaison entre la nappe textile et la feuille de verre est obtenue au moyen d'une résine. Selon une première variante d'assemblage, on peut positionner la nappe textile et la feuille de verre à une distance constante au moyen d'une pluralité d' entretoises agencées en périphérie. On injecte alors la résine dans le volume défini entre la nappe textile et la feuille de verre.Thus, according to a first embodiment, at least one layer of the glass complex comprises a glass sheet and a resin interposed between the textile sheet and the glass sheet. In other words, the bond between the textile web and the glass sheet is obtained by means of a resin. According to a first assembly variant, the textile web and the glass sheet can be positioned at a constant distance by means of a plurality of spacers arranged at the periphery. The resin is then injected into the volume defined between the textile web and the glass sheet.
Selon une seconde variante d'assemblage la résine peut être directement appliquée à la surface de la nappe textile, puis c'est la feuille de verre qui vient au contact de la résine.According to a second assembly variant, the resin can be directly applied to the surface of the textile web, and then the glass sheet comes into contact with the resin.
En pratique, la résine peut être formée dans un matériau choisi parmi le groupe comprenant les polyépoxydes, les polyuréthannes, les polyesters et les acryliques. Les polyesters peuvent polymériser à température ambiante ou de préférence en élevant la température. Les acryliques peuvent, quant à eux, être réticulés au moyen d'un rayonnement ultraviolet sans modifier leur température.In practice, the resin may be formed from a material selected from the group consisting of polyepoxides, polyurethanes, polyesters and acrylics. The polyesters can polymerize at room temperature or preferably by raising the temperature. Acrylics can themselves be crosslinked by means of ultraviolet radiation without changing their temperature.
Selon un second mode de réalisation, au moins une couche de complexe verrier peut comprendre une feuille de verre et un film interposé entre la nappe textile et la feuille de verre.According to a second embodiment, at least one layer of glass complex may comprise a glass sheet and a film interposed between the textile sheet and the glass sheet.
Dans ce cas, le film permet de réaliser la liaison entre, d'une part, la nappe textile et, d'autre part, la feuille de verre. Un tel assemblage est complexe àréaliser et, pour ne pas endommager le textile, il est nécessaire de trouver un compromis entre les paramètres que son la température, la durée et la pression utilisée. En effet, la pression du procédé d'assemblage peut varier de 1 à 20 bars et la température être comprise entre 80 et 1800C notamment. De telles conditions sont généralement réalisées au moyen d'un autoclave, d'une poche à vide, de calandres ou d'une presse. Un tel film présente généralement une épaisseur comprise entre 1 et 5 mm.In this case, the film makes it possible to make the connection between, on the one hand, the textile web and, on the other hand, the glass sheet. Such an assembly is complex to realize and, in order not to damage the textile, it is necessary to find a compromise between the parameters that its the temperature, the duration and the pressure used. Indeed, the pressure of the assembly process can vary from 1 to 20 bar and the temperature is between 80 and 180 0 C in particular. Such conditions are generally achieved by means of an autoclave, a vacuum bag, calenders or a press. Such a film generally has a thickness of between 1 and 5 mm.
Un tel procédé d'assemblage est généralement couplé à une opération de "dégazage" et permet de réduire au minimum l'interstice d'air présent entre les deux couches en regard des intermédiaires de liaison que sont la résine ou le film. L'air contenu dans le complexe est aspiré en périphérie au niveau des extrémités libres des fibres optiques. Ainsi, cette étape d'assemblage nécessite l'utilisation d'un support compressible pour protéger ces extrémités libres de la chaleur et de la pression appliquée sur le complexe. De plus lors de cette étape, les fibres doivent rester immobiles et ne pas se chevaucher.Such an assembly method is generally coupled to a "degassing" operation and makes it possible to minimize the air gap present between the two layers opposite the bonding intermediates that are the resin or the film. The air contained in the complex is sucked at the periphery at the free ends of the optical fibers. Thus, this assembly step requires the use of a compressible support to protect these free ends from heat and pressure. applied on the complex. In addition during this step, the fibers must remain stationary and not overlap.
Avantageusement, le film peut être formé dans un matériau choisi parmi le groupe comprenant l'Ethylene Vivinyl Acétate (EVA), les Polyuréthannes thermoplastiques (TPU) et le Polybutyral de Vinyl (PVB).Advantageously, the film may be formed from a material selected from the group consisting of Ethylene Vivinyl Acetate (EVA), Thermoplastic Polyurethanes (TPU) and Polybutyral Vinyl (PVB).
Selon un mode de réalisation particulier, les fibres optiques peuvent être formées chacune par une âme gainée d'un polymère fluoré.According to a particular embodiment, the optical fibers may each be formed by a core sheathed with a fluoropolymer.
L'âme des fibres optiques peut, quant à elle, être formée dans un matériau choisi parmi le groupe comprenant le polyméthacrylate de méthyle (PMMA) et le polycarbonate (PC). La combinaison des fibres optiques comportant une âme réalisée en polycarbonate (PC) avec TPU assemblées à 1200C, a donné de bons résultats en termes de retrait du film. En effet, cette combinaison permet de générer peu, voire pas, des phénomènes de bullage entre la nappe textile et le film.The core of the optical fibers may, for its part, be formed of a material chosen from the group comprising polymethyl methacrylate (PMMA) and polycarbonate (PC). The combination of optical fibers comprising a core made of polycarbonate (PC) with TPU assembled at 120 ° C., gave good results in terms of shrinkage of the film. Indeed, this combination makes it possible to generate little or no bubbling phenomena between the textile web and the film.
Pour d'autres applications, les fibres optiques peuvent également être formées par des fils de verre aptes à transmettre et à émettre latéralement la lumière.For other applications, the optical fibers can also be formed by glass son able to transmit and emit light laterally.
En pratique, les fils de liage peuvent être formés dans un matériau choisi parmi le groupe comprenant les fils ou fibres naturels, artificiels ou synthétiques. Ainsi, des fils de polyamide ou de polyester peuvent notamment être utilisés comme fils de liage ou de fond.In practice, the binding yarns may be formed from a material selected from the group consisting of natural, artificial or synthetic yarns or fibers. Thus, polyamide or polyester son may especially be used as binding son or background.
Par ailleurs, la nappe textile intégrant les fibres optiques peut être éclairée de diverses manières et notamment au moyen de sources ponctuelles telles des diodes électroluminescentes.Furthermore, the textile web incorporating the optical fibers can be illuminated in various ways and in particular by means of point sources such as light emitting diodes.
Ainsi, selon un mode de réalisation particulier, le complexe éclairant peut comprendre au niveau d'au moins une lisière une pluralité de sources ponctuelles agencées en regard d'au moins une extrémité libre de fibres optiques. Autrement dit, les sources ponctuelles peuvent être agencées directement au niveau des arêtes des feuilles de verre formant la lisière du complexe éclairant.Thus, according to a particular embodiment, the illuminating complex may comprise at least one selvedge a plurality of point sources arranged facing at least one free end of optical fibers. In other words, the point sources can be arranged directly at the edges of the glass sheets forming the edge of the illuminating complex.
Selon une première variante, les fibres optiques peuvent s'étendre en dehors de la surface définie par les feuilles de verre et peuvent être regroupées en faisceaux au niveau de la lisière du complexe éclairant. Dans ce cas, une source étendue peut permettre d'éclairer une pluralité d'extrémités libres de fibres optiques. Par ailleurs, des systèmes optiques permettant de collimater la lumière émise par les sources étendues peuvent être interposés entre la source ponctuelle et le faisceau de fibres optiques.According to a first variant, the optical fibers may extend outside the surface defined by the glass sheets and may be grouped into bundles at the edge of the illuminating complex. In this case, an extended source can illuminate a plurality of free ends of optical fibers. In addition, optical systems for collimating the light emitted by the extended sources can be interposed between the point source and the optical fiber bundle.
Selon une seconde variante, le complexe peut comprendre, au niveau d'au moins une lisière, une source étendue agencée en regard d'une pluralité d'extrémités libres de fibres optiques.According to a second variant, the complex may comprise, at the level of at least one selvedge, an extended source arranged facing a plurality of free ends of optical fibers.
En effet, le long de la structure éclairante, on peut agencer un tube fluorescent permettant d'éclairer une pluralité d'extrémités libres de fibres optiques. Un système optique collimateur peut également être interposé entre le tube fluorescent et les extrémités libres.Indeed, along the illuminating structure, one can arrange a fluorescent tube for illuminating a plurality of free ends of optical fibers. A collimating optical system may also be interposed between the fluorescent tube and the free ends.
Un tel complexe éclairant peut comporter des surfaces dépolies permettant d'augmenter le pouvoir de diffusion de la nappe textile. Ses formes peuvent être planes ou gauches, puisque le textile peut s'adapter à la forme des feuilles de verre avec lesquelles il est assemblé.Such an illuminating complex may include frosted surfaces to increase the diffusion power of the textile web. Its forms can be flat or left, since the textile can adapt to the shape of the glass sheets with which it is assembled.
Le complexe peut également présenter une transparence totale lorsqu'il n'est pas éclairé. Cependant, l'énergie lumineuse qu'il émet peut permettre de le rendre translucide ou sensiblement opaque et permettre de masquer une zone située à l'arrière du dispositif.The complex can also be completely transparent when it is not lit. However, the light energy that it emits can make it translucent or substantially opaque and can hide an area at the rear of the device.
D'éventuelles nanocharges, invisibles à l'oeil nu, peuvent être noyées dans les feuilles de verre de manière à améliorer la diffusion de la lumière émise par les fibres optiques. DESCRIPTION SOMMAIRE DES FIGURESAny nanofillers, invisible to the naked eye, can be embedded in the glass sheets so as to improve the diffusion of the light emitted by the optical fibers.

Les figures 2 à 4 sont des vues de face d'un complexe verrier associé avec différentes variantes de source lumineuse agencées au niveau de ses lisières.Figures 2 to 4 are front views of a glass complex associated with different light source variants arranged at its edges.
MANIERE DE DECRIRE L'INVENTION Comme déjà évoqué, l'invention concerne un complexe verrier éclairant (1) qui, tel que représenté à la figure 1, comprend une nappe textile (2) noyée entre deux couches (5, 6) du complexe verrier. Une telle nappe textile (2) intègre des fibres optiques (3) permettant de transmettre latéralement de la lumière à l'intérieur des deux couches (5, 6) du complexe verrier.DESCRIPTION OF THE INVENTION As already mentioned, the invention relates to an illuminating glass complex (1) which, as represented in FIG. 1, comprises a textile ply (2) embedded between two layers (5, 6) of the glass complex . Such a textile web (2) incorporates optical fibers (3) for laterally transmitting light inside the two layers (5, 6) of the glass complex.
Ces fibres optiques (3) sont par ailleurs associées, voire tissées avec des fils de liage (4, 14) qui peuvent être des fils de fond (4) desquels émergent de manière périodique des fils de liage (14) pour donner une certaine tenue à la nappe textile de fond.These optical fibers (3) are furthermore associated, or even woven, with binding yarns (4, 14) which may be background yarns (4) from which periodically bonding yarns (14) emerge to give a certain amount of holding power. to the textile ground cloth.
Les couches (5, 6) du complexe verrier peuvent se présenter sous la forme d'un empilement de plusieurs éléments. Telle que représentée, la couche (5) peut comporter une résine (25) au contact de la nappe textile (2) et une feuille de verre (15) rapportée sur cette résine (25).The layers (5, 6) of the glass complex may be in the form of a stack of several elements. As shown, the layer (5) may comprise a resin (25) in contact with the textile web (2) and a glass sheet (15) attached to this resin (25).
La couche (6) peut quant à elle, être constituée de manière analogue ou différente. Ainsi, cette couche (6) peut comporter un film (26) également mis au contact de la nappe textile (2), puis une feuille de verre (16) est rapportée sur ce film (26).The layer (6) can itself be constituted in a similar way or different. Thus, this layer (6) may comprise a film (26) also brought into contact with the textile web (2), then a glass sheet (16) is attached to this film (26).
Par ailleurs, et dans certains cas particuliers, il peut être avantageux de rapporter une couche de finition (7) à la surface de l'une des feuilles de verre (16). Une telle couche de finition (7) peut notamment avoir une fonction réfléchissante, diffusante, anti-reflet, dépolluante, ou autre.Moreover, and in some particular cases, it may be advantageous to bring a topcoat (7) to the surface of one of the glass sheets (16). Such a topcoat (7) may in particular have a reflective function, diffusing, anti-reflection, depolluting, or other.
Pour certaines applications, un tel complexe verrier peut être quasiment transparent en utilisant une nappe textile dans laquelle les fils de liage sont des fils de polyamide de l'ordre de quelques dizaines de deniers, typiquement 20 deniers et sont au nombre maximum de quelques dizaines de fils par centimètre, par exemple 30 fils par centimètre.For some applications, such a glass complex can be almost transparent using a textile web in which the binding son are polyamide son of the order of a few tens of deniers, typically 20 deniers and are at maximum number of a few tens of threads per centimeter, for example 30 threads per centimeter.
Les fibres optiques peuvent quant à elles être de l'ordre de la dizaine au centimètre et présenter un diamètre de quelques dixièmes de millimètres. En effet, plus l'espacement est important entre les fibres optiques, meilleure est la transparence du complexe.The optical fibers may be of the order of ten to one centimeter and have a diameter of a few tenths of a millimeter. Indeed, the greater the spacing between the optical fibers, the better the transparency of the complex.
Tel que représenté à la figure 2, un tel complexe verrier (1) peut être associé à une pluralité de sources de lumière ponctuelle (9) rapportées au niveau de l'une de ses lisières (8). Par ailleurs, les fibres optiques peuvent être regroupées sous la forme de faisceaux (10), de manière à faire coopérer une pluralité d'extrémités libres en regard d'une même source de lumière ponctuelle (9).As represented in FIG. 2, such a glass complex (1) can be associated with a plurality of point light sources (9) reported at one of its selvedges (8). Moreover, the optical fibers can be grouped together in the form of beams (10), so as to make a plurality of free ends cooperate with one and the same point light source (9).
Selon un autre mode de réalisation tel que représenté à la figure 3, les sources de lumière ponctuelle (19) peuvent être également directement agencées au niveau de la lisière (18) du complexe verrier. De cette manière, la nappe textile peut être sectionnée au niveau de la lisière (18). Un tel agencement permet de réduire les opérations de confection et de regroupement des fibres optiques les unes avec les autres sous la forme de faisceau.According to another embodiment as shown in Figure 3, the point light sources (19) can also be directly arranged at the edge (18) of the glass complex. In this way, the textile web can be cut at the selvedge (18). Such an arrangement makes it possible to reduce the operations of making and grouping the optical fibers together in the form of a bundle.
Tel que représenté à la figure 4, le complexe verrier (1) peut également être éclairé au moyen d'une source de lumière étendue (29), mis en regard d'une lisière (28). Une telle source de lumière étendue (29) peut notamment se représenter sous la forme d'un tube fluorescent ou d'un tube à décharge incorporant un gaz tel que du néon.As shown in Figure 4, the glass complex (1) can also be illuminated by means of an extended light source (29), facing a selvedge (28). Such an extended light source (29) may in particular be in the form of a fluorescent tube or a discharge tube incorporating a gas such as neon.
Il ressort de ce qui précède qu'un complexe éclairant verrier conforme à l'invention et présente de multiples avantages, et notamment il permet :It follows from the above that an illuminating glass complex in accordance with the invention and has multiple advantages, and in particular it allows:
" de réaliser une lumière sur une surface sans générer de marques disgracieuses au complexe à fabriquer dans la structure verrière ;to realize a light on a surface without generating unsightly marks to the complex to be manufactured in the glass structure;
