Les diodes sont agencées sur une série de cartes de circuits imprimés, l'ensemble étant noyé dans un plastique transparent. Le document US 2004/031234 A1 divulgue toutes les caractéristiques du préambule de la revendication 1.For example, the patent application US2004031234 proposes an illuminating window with diodes, consisting of an insulating double glazing with diodes assembled to the edge of the glazing via a U-shaped section with a central core facing the edge of the double glazing and at the distal ends two lateral parts enclosing the borders external main faces of the insulating double glazing. The diodes are arranged on a series of printed circuit boards, the assembly being embedded in a transparent plastic. The document US 2004/031234 A1 discloses all the features of the preamble of claim 1.

L'invention a donc pour but de proposer un vitrage multiple éclairant à diodes, alternatif ayant notamment à la fois des performances optiques et les performances classiques requises pour les fenêtres (thermique, mécanique ...).The object of the invention is therefore to propose an alternative diode-illuminating multi-glazing unit having, in particular, both optical performance and the conventional performance required for windows (thermal, mechanical, etc.).

Dans la suite de la description, la « longueur » d'un élément correspond à la grandeur longitudinale dudit élément. La « largeur » de l'élément correspond à la dimension transversale à la longueur et coplanaire à celle-ci, tandis que « l'épaisseur » s'entend par l'extension orthogonale à la largeur et la longueur.In the remainder of the description, the "length" of an element corresponds to the longitudinal magnitude of said element. The "width" of the element corresponds to the dimension transverse to the length and coplanar with it, while "the thickness" is understood by the extension orthogonal to the width and the length.

L'invention est relative à un ensemble éclairant comprenant

  • un vitrage multiple isolant et éclairant, en particulier pour être entre un extérieur et un intérieur de bâtiment ou de véhicule, le vitrage comprenant au moins une première et deuxième feuilles de verre espacées entre elles (via un espaceur) avec des première et deuxième tranches respectives, et associées par un moyen d'étanchéité périphérique entre les feuilles de verre, tel que du mastic,

L'ensemble ne comporte aucun élément, même un autre profilé, de type en U notamment, qui serait susceptible de créer des ponts thermiques.The assembly has no element, even another profile, U-type in particular, which would likely create thermal bridges.

Le vitrage isolant peut être un vitrage isolant usuel pour lequel les deux feuilles de verre sont espacées par une lame d'air ou de gaz. En variante, il peut s'agir d'un vitrage sous vide.The insulating glazing unit may be a conventional insulating glazing unit for which the two glass sheets are spaced apart by a blade of air or gas. Alternatively, it may be a vacuum glazing.

On entend par « association », le fait d'être apposé contre, en y étant fixé ou non.By "association" is meant to be affixed against, whether fixed or not.

Le profilé forme des moyens de support du système d'éclairage ainsi que des moyens servant à l'association dudit système d'éclairage au vitrage, l'association du profilé étant constituée d'un assemblage avec le vitrage, de préférence amovible, ou d'une apposition contre le vitrage.The profile forms means for supporting the lighting system as well as means for associating said lighting system with the glazing, the association of the profile consisting of an assembly with the glazing, preferably removable, or an apposition against the glazing.

Selon une caractéristique, l'ensemble comporte une pièce apte à maintenir un écartement entre la face éclairante des diodes et le vitrage (la tranche du vitrage), la pièce pouvant être partie du profilé. La pièce est notamment rapportée, voire fixée, sur la base du profilé ; elle est en saillie par rapport à la base au moins dans une partie centrale en regard de l'espaceur du vitrage, en étant de largeur inférieure à la base voire de largeur égale à l'espaceur. La pièce peut être monobloc ou être en plusieurs pièces. Elle peut être formée en un élément monobloc avec la base du profilé. La pièce ou le profilé peut être de section rectangulaire, en L (selon un retour à 90°), ou en T (renversé) ou présenter deux créneaux en U retourné, la concavité des U étant tournée vers la base, en particulier en regard des tranches des deux feuilles de verre. La pièce indépendante du profilé ou la partie du profilé formant la pièce d'écartement peut être en matière plastique ou métallique ou composite. La pièce peut être faite de différents matériaux, au moins une partie pouvant être métallique (partie(s) latérale(s) et/ou centrale), sans qu'aucune partie métallique (monobloc ou plusieurs pièces aboutées) ne soit à la fois en contact avec les deux feuilles de verreAccording to one characteristic, the assembly comprises a part capable of maintaining a spacing between the illuminating face of the diodes and the glazing (the edge of the glazing), the part possibly being part of the profile. The piece is particularly reported or fixed, on the base of the profile; it is projecting from the base at least in a central part facing the spacer of the glazing, being of width less than the base or even width equal to the spacer. The piece can be monobloc or be in several pieces. It can be formed in a monobloc element with the base of the profile. The part or profile may be of rectangular section, in L (according to a return to 90 °), or in T (reversed) or have two U-shaped slots returned, the concavity of the U being turned towards the base, in particular facing slices of the two sheets of glass. The independent part of the profile or the part of the profile forming the spacer may be plastic or metal or composite material. The part may be made of different materials, at least one part may be metallic (part (s) side (s) and / or central), without any metal part (monobloc or more abutments) is both in contact with the two glass sheets

Les diodes ne risquent pas de toucher le module. Elles sont protégées. Elles ne font pas saillie en dehors de la surface du profilé la plus proche du module.The diodes are not likely to touch the module. They are protected. They do not protrude outside the surface of the profile closest to the module.

Selon une autre caractéristique, l'ensemble comporte une surface pleine issue d'une pièce rapportée ou du profilé, la surface pleine étant apte à former une butée d'appui pour le vitrage (et une butée de support pour le vitrage vis-à-vis de son poids). Cette surface pleine est de largeur équivalente (égale) à l'épaisseur du vitrage pour le côté inférieur du vitrage dans sa position montée, et est disposée contre la totalité de la largeur de la tranche du vitrage (sans dépasser). En fonction du matériau de cette surface au droit des diodes, si celui-ci n'est pas transparent, la surface pleine sera trouée au droit des diodes. Pour le côté inférieur du vitrage, le profilé s'étend avantageusement sur toute la longueur du côté afin de former une surface d'appui conséquente au regard du poids du vitrage.According to another characteristic, the assembly comprises a solid surface resulting from an insert or from the profile, the solid surface being able to form a bearing abutment for the glazing (and a support abutment for the glazing vis-à- screw of its weight). This solid surface is of width equivalent (equal) to the thickness of the glazing for the lower side of the glazing in its mounted position, and is disposed against the entire width of the edge of the glazing (without exceeding). Depending on the material of this surface to the right of the diodes, if it is not transparent, the solid surface will be perforated to the right of the diodes. For the lower side of the glazing, the profile advantageously extends over the entire length of the side to form a substantial bearing surface with respect to the weight of the glazing.

Dans un mode de réalisation, le profilé est posé ou rapporté, en particulier uniquement, contre la tranche du vitrage sans être rendu solidaire.In one embodiment, the profile is placed or reported, in particular only, against the edge of the glazing without being made integral.

Dans un autre mode de réalisation, le profilé est fixé, en particulier uniquement au niveau de la tranche du vitrage, de préférence au moins au niveau du moyen d'étanchéité, par des moyens de fixation de préférence amovibles. Les moyens de fixation ne sont pas traversants à l'intérieur du vitrage, entre les feuilles de verre, pour garantir l'étanchéité du vitrage.In another embodiment, the profile is fixed, in particular only at the edge of the glazing unit, preferably at least at the level of the sealing means, by preferably removable fastening means. The fixing means are not through the glazing, between the glass sheets, to ensure the sealing of the glazing.

Les moyens de fixation sont choisis parmi un adhésif double face, ou des moyens mécaniques de type vis ou de clipsage, notamment coopérant avec un insert, en particulier une cheville, monté dans le moyen d'étanchéité qui est en particulier pourvu d'une cavité notamment moulée.The fixing means are chosen from a double-sided adhesive, or mechanical means of screw or clipping type, in particular cooperating with an insert, in particular an anchor, mounted in the sealing means which is in particular provided with a particularly molded cavity.

Le profilé comprend une partie centrale présentant un moyen de guidage pour le positionnement du profilé vis-à-vis du vitrage, ce qui procure une rapidité de montage du profilé qui est correctement positionné en étant centré sur la tranche du vitrage pour ne pas dépasser de ses bords et assurer l'alignement des diodes avec la ou les tranches des feuilles de verre. Le moyen de guidage est par exemple constitué d'au moins deux trous à proximité respectivement des deux extrémités du profilé, et de préférence d'une pluralité de trous répartis et alignés le long de l'axe central longitudinal du profilé.The profile comprises a central portion having a guide means for positioning the profile vis-à-vis the glazing, which provides a rapid assembly of the profile which is correctly positioned by being centered on the edge of the glazing to not exceed its edges and ensure the alignment of the diodes with the slice or slices of glass sheets. The guiding means consists for example of at least two holes near respectively the two ends of the profile, and preferably a plurality of holes distributed and aligned along the longitudinal central axis of the profile.

Le profilé présente une partie dite supérieure en matière isolante thermiquement telle que de la matière plastique, la partie supérieure étant en regard et apposée contre le vitrage, au moins dans une zone qui n'est pas en regard des diodes, notamment dans une zone dite centrale en regard de l'espaceur du vitrage, ladite partie supérieure faisant partie intégrante du profilé ou étant une pièce rapportée. La partie supérieure du profilé s'étend selon la largeur de la première tranche et la largeur des moyens d'étanchéité, et de préférence selon la largeur de la deuxième tranche du vitrage.The profile has a so-called upper part of thermally insulating material such as plastic, the upper part being facing and affixed against the glazing, at least in an area which is not facing the diodes, especially in a so-called area. central facing the glazing spacer, said upper part being an integral part of the profile or being an insert. The upper part of the profile extends along the width of the first wafer and the width of the sealing means, and preferably according to the width of the second wafer of the glazing.

Selon une autre caractéristique, le profilé comporte une partie supérieure ou l'ensemble comporte une pièce, notamment dans une zone dite centrale en regard de l'espaceur du vitrage, la partie supérieure du profilé ou la pièce étant en saillie des diodes et constitue une entretoise entre les diodes et le vitrage et/ou une surface d'appui pour le vitrage au moins pour le côté inférieur du vitrage en utilisation du vitrage. La partie supérieure ou la pièce forme ainsi une surface d'interface entre l'extrémité supérieure des diodes et le vitrage, protégeant les diodes d'un éventuel choc lorsque le profilé est rapporté contre la tranche du vitrage. En outre, lorsque le profilé est monté contre le côté inférieur du vitrage, cette partie supérieure ou pièce en tant que surface d'appui sert à supporter le poids du vitrage.According to another characteristic, the profile comprises an upper part or the assembly comprises a part, in particular in a so-called central zone facing the spacer of the glazing, the upper part of the profile or the part being projecting from the diodes and constitutes a spacer between the diodes and the glazing and / or a bearing surface for the glazing at least for the lower side of the glazing in use of the glazing. The upper part or the part thus forms an interface surface between the end upper diodes and the glazing, protecting the diodes from a possible shock when the profile is reported against the edge of the glazing. In addition, when the profile is mounted against the lower side of the glazing, this upper part or piece as a bearing surface is used to support the weight of the glazing.

Le profilé comporte avantageusement un ou des logements, de préférence un logement en regard de chaque tranche de feuille de verre, qui accueillent les diodes et leur dispositif PCB sans que les diodes ne fassent saillie au-delà du plan dit supérieur du profilé d'association au vitrage.The profile advantageously comprises one or more housings, preferably a housing facing each slice of glass sheet, which accommodate the diodes and their PCB device without the diodes protruding beyond the upper plane of the association profile to the glazing.

Selon l'invention, le profilé présente un fond ou base opposé au vitrage, et comporte des moyens de dissipation de la chaleur qui sont associés au dispositif PCB, les moyens de dissipation de la chaleur étant métalliques logés contre le fond ou constitutifs dudit fond.According to the invention, the profile has a bottom or base opposite the glazing, and comprises heat dissipation means which are associated with the PCB device, the heat dissipating means being metal housed against the bottom or constituting said bottom.

Le profilé peut présenter deux parties métalliques latérales, formant en particulier des moyens de dissipation de la chaleur associés au dispositif PCB, les deux parties métalliques latérales étant séparées des feuilles de verre, notamment des tranches des feuilles de verre, par de la matière thermiquement isolante de type joint, ou colle, ou espacées des feuilles par de l'air.The profile may have two lateral metal parts, forming in particular heat dissipation means associated with the PCB device, the two lateral metal parts being separated from the glass sheets, in particular the slices of the glass sheets, by thermally insulating material seal type, or glue, or spaced sheets by air.

Le système d'éclairage est agencé au niveau du côté horizontal inférieur du vitrage en position montée d'utilisation du vitrage, le profilé formant au moins une butée d'appui et de support de la tranche du vitrage, de préférence une seule butée longitudinale sur la majorité voire toute longueur du côté horizontal inférieur, et/ou de préférence la ou plusieurs butées étant disposées, dans les zones hors diodes, sur la majorité voire toute la largeur de la tranche du vitrage.The lighting system is arranged at the lower horizontal side of the glazing in the mounted position of use of the glazing unit, the profile forming at least one abutment for supporting and supporting the edge of the glazing, preferably a single longitudinal stop on the majority or even any length of the lower horizontal side, and / or preferably one or more stops being arranged, in the non-diode zones, over the majority or even the entire width of the edge of the glazing.

Dans un mode de réalisation, le profilé comporte une base et un capot, solidaire ou amovible, capotant les diodes et les PCB et apte à laisser passer la lumière des diodes vers le vitrage. Le capot est avantageusement creux en regard de la base, avec par exemple au moins une section en U retourné ou en Ω, le creux du U formant un logement d'accueil des diodes. Le capot peut être transparent au moins au droit des diodes pour laisser passer la lumière. Dans une variante préférée, il comporte des orifices, de forme par exemple circulaires ou oblongues, qui sont en regard des diodes.In one embodiment, the profile comprises a base and a cover, integral or removable, covering the diodes and PCBs and able to let the light from the diodes to the glazing. The cover is advantageously hollow facing the base, with for example at least one U-shaped section turned upside down or Ω, the hollow of the U forming a housing for receiving the diodes. The cover can be transparent at least to the right of the diodes to let the light. In a preferred embodiment, it has orifices, of circular or oblong shape, for example, which face the diodes.

Le profilé ne s'étend pas en regard des faces principales du vitrage, de préférence le profilé présente une largeur au plus équivalente (égale) à l'épaisseur du vitrage et de préférence en regard des tranches des deux feuilles de verre. Ainsi, de préférence seul un encadrement du type encadrement pour fenêtre, tel qu'une pareclose, pourrait être en regard des faces principales du vitrage. Cet encadrement accueillerait la périphérie de l'ensemble de l'invention, l'encadrement logeant la périphérie du vitrage et le profilé associé au vitrage et porteur du système d'éclairage, cette périphérie étant associée à l'encadrement en y intercalant des moyens d'étanchéité du type joint. Cet encadrement serait par exemple en U et/ou métallique. Seul cet encadrement du type usuel présenterait des retours associés aux faces externes du vitrage. Par conséquent, aucun profilé distinct de l'encadrement ne s'étend selon l'invention en regard des faces principales du vitrage.The profile does not extend facing the main faces of the glazing, preferably the profile has a width at most equivalent (equal) to the thickness of the glazing and preferably facing the edges of the two sheets of glass. Thus, preferably only a frame like window frame, such as a pareclose, could be opposite the main faces of the glazing. This frame would host the periphery of the assembly of the invention, the frame housing the periphery of the glazing and the profile associated with the glazing and carrying the lighting system, this periphery being associated with the frame by interposing means of seal type seal. This frame would be for example U and / or metal. Only this framework of the usual type would present returns associated with the outer faces of the glazing. Therefore, no profile separate from the frame extends according to the invention facing the main faces of the glazing.

Le système d'éclairage est résistant à l'eau par un revêtement de protection des diodes et de la face du dispositif PCB porteuse des diodes.The lighting system is water resistant by a protective coating of the diodes and the face of the PCB device carrying the diodes.

Les PCB et diodes sont revêtus d'une peinture d'isolation électrique et sont résistants à l'eau.PCBs and diodes are coated with electrical insulation paint and are water resistant.

Selon l'invention, l'ensemble éclairant est de préférence intégré dans un encadrement, éventuellement en reposant sur des cales lorsqu'il forme avec l'encadrement une fenêtre, le profilé ne faisant pas saillie au-delà des faces externes du vitrage pour ne pas gêner les retours de l'encadrement associés aux faces externes du vitrage.According to the invention, the illuminating assembly is preferably integrated in a frame, possibly resting on wedges when it forms with the frame a window, the profile not projecting beyond the external faces of the glazing to not hinder the returns of the frame associated with the external faces of the glazing.

L'encadrement peut être en bois, PVC, métallique (aluminium) etc...The frame can be wood, PVC, metal (aluminum) etc ...

La figure 1 illustre un ensemble éclairant selon l'invention monté dans un encadrement de menuiserie 1B pour former une fenêtre 1A. L'ensemble éclairant comprend un vitrage isolant et éclairant 1 installé via des cales 8 dans la menuiserie qui est en particulier pourvue d'une pareclose 1C.The figure 1 illustrates an illuminating assembly according to the invention mounted in a carpentry frame 1B to form a window 1A. The illuminating assembly comprises insulating and illuminating glazing 1 installed via wedges 8 in the carpentry which is in particular provided with a 1C bead.

Selon l'invention, le vitrage 1 de la fenêtre est éclairant, un système d'éclairage à base de diodes électroluminescentes lui est associé via au moins un profilé 3 visible en pointillés et caché dans le dormant via la pareclose 1C.According to the invention, the glazing 1 of the window is illuminating, a lighting system based on light-emitting diodes is associated with it via at least one section 3 visible dashed and hidden in the frame via the 1C pareclose.

De préférence, en position montée du vitrage dans le dormant, le vitrage est associé à un profilé dit inférieur 3 et un profilé dit supérieur 3A.Preferably, in the mounted position of the glazing in the frame, the glazing is associated with a so-called lower profile 3 and a so-called upper profile 3A.

Le vitrage isolant et éclairant 1 illustré partiellement en coupe sur les figures en particulier 2 et 3 comporte de manière connue deux feuilles de verre 10 et 11 séparées par une lame d'air ou de gaz 12, un intercalaire ou cadre entretoise 13, dénommé également « espaceur », qui sert à maintenir écartées les deux feuilles de verre, et des moyens d'étanchéité 14 qui réalisent l'étanchéité de l'intérieur des feuilles de verre vis-à-vis de l'extérieur.The insulating and illuminating glazing 1 partially illustrated in section in the figures in particular 2 and 3 comprises, in known manner, two sheets of glass 10 and 11 separated by an air or gas blade 12, a spacer or spacer frame 13, also known as "Spacer", which serves to keep apart the two sheets of glass, and sealing means 14 which seal the interior of the glass sheets vis-à-vis the outside.

Usuellement, l'intercalaire 13 est fixé à l'intérieur du vitrage par ses faces latérales aux faces internes des feuilles de verre par du caoutchouc butyl 15 qui a également pour rôle de rendre étanche l'intérieur du vitrage à la vapeur d'eau. L'intercalaire 13 est disposé en retrait à l'intérieur du vitrage et à proximité des tranches 10A et 11A desdites feuilles de verre, de façon à ménager une gorge périphérique dans laquelle sont injectés les moyens d'étanchéité 14 du type mastic, tel qu'en polysulfure ou polyuréthane. Le mastic confirme l'assemblage mécanique des deux feuilles de verre et assure une étanchéité à l'eau liquide ou aux solvants.Usually, the insert 13 is fixed inside the glazing by its side faces to the internal faces of the glass sheets by butyl rubber 15 which also serves to seal the interior of the glazing with water vapor. The insert 13 is set back inside the glazing and close to the slices 10A and 11A of said glass sheets, so as to provide a peripheral groove into which are injected the sealing means 14 of the putty type, such as in polysulfide or polyurethane. The mastic confirms the mechanical assembly of the two glass sheets and ensures a seal with liquid water or solvents.

Le vitrage présente par exemple les épaisseurs suivantes : 4 mm pour chaque des tranches des feuilles de verre et 16 mm d'épaisseur de lame de gaz.The glazing has, for example, the following thicknesses: 4 mm for each of the slices of the glass sheets and 16 mm thickness of the gas strip.

Selon l'invention, le vitrage 1 est éclairant grâce à un système d'éclairage 2 à base de diodes qui est associé audit vitrage via les profilés inférieur 3 et supérieur 3A.According to the invention, the glazing 1 is illuminating thanks to a lighting system 2 based on diodes which is associated with said glazing via the lower 3 and upper 3A profiles.

Le système d'éclairage 2 coopère avec la tranche 1A du vitrage, plus particulièrement avec les tranches 10A et 11A des feuilles de verre pour diriger la lumière vers lesdites tranches.The lighting system 2 cooperates with the slice 1A of the glazing, more particularly with the slices 10A and 11A of the glass sheets to direct the light towards said slices.

Le système d'éclairage 2 est positionné contre au moins un côté du vitrage (sur toute ou partie de la longueur) et peut s'étendre par exemple sur deux côtés opposés, voire même sur l'ensemble de la périphérie, au niveau du bas, du haut, des côtés en position d'utilisation du vitrage. Sur deux côtés, il est de préférence associé en haut et en bas du vitrage en position montée de la fenêtre, tel qu'illustré ici.The lighting system 2 is positioned against at least one side of the glazing (over all or part of the length) and can extend for example on two opposite sides, or even over the entire periphery, at the bottom. , from the top, of the sides in position of use of the glazing. On two sides, it is preferably associated at the top and bottom of the window in the mounted position of the window, as shown here.

Le système d'éclairage comporte des diodes 20 qui sont disposées de manière connue sur des dispositifs de support et d'alimentation électrique 21, du type PCB pour « Printed Circuit Board » en anglais. Un vernis isolant électrique est prévu sur les connexions des diodes. Les PCB sont connectés les uns aux autres. Avant de sortir de la menuiserie percée dans un coin (haut ou bas selon besoin), un câble électrique non illustré chemine dans le dormant à proximité du profilé 3.The lighting system comprises diodes 20 which are arranged in a known manner on support and power supply devices 21, of the PCB type for "Printed Circuit Board" in English. An electrical insulating varnish is provided on the diode connections. PCBs are connected to each other. Before leaving the joinery pierced in a corner (up or down as needed), an unillustrated electric cable runs in the frame near the profile 3.

Le système d'éclairage 2 est de préférence résistant à l'eau (« waterproof »), les diodes étant recouvertes d'une résine protectrice waterproof. En effet, de l'eau ou de la condensation est toujours susceptible de s'immiscer dans la menuiserie.The lighting system 2 is preferably waterproof ("waterproof"), the diodes being covered with a waterproof protective resin. Indeed, water or condensation is always likely to interfere in the carpentry.

La taille des diodes est par exemple de 3,5 mm x 2,8 mm.The size of the diodes is, for example, 3.5 mm × 2.8 mm.

De préférence, l'éclairage étant à base de diodes, le vitrage comprend des moyens de diffusion 6 de la lumière associés aux faces du verre, soit préférentiellement à l'extérieur du vitrage sur les faces externes 10B et 11B (figure 2), soit à l'intérieur (non illustré).Preferably, the illumination being based on diodes, the glazing comprises light diffusion means 6 associated with the faces of the glass, or preferably outside the glazing on the outer faces 10B and 11B ( figure 2 ), either indoors (not shown).

Les moyens de diffusion 6 sont de préférence sérigraphiés sur le verre et sont par exemple de l'émail blanc. Ils s'étendent sur le verre selon un agencement et des motifs choisis. Ils ne recouvrent pas forcément la totalité de la surface du verre du module et peuvent ainsi délimiter des zones dites sombres fonctionnelles. Les zones sombres sont par exemple disposées de manière centrale ou périphérique au module. Elles consistent par exemple en des zones transparentes (clair de vitre) ou opaques telles qu'un émail décoratif, ou encore en des miroirs.The diffusion means 6 are preferably screen printed on the glass and are for example white enamel. They extend over the glass according to a chosen arrangement and patterns. They do not necessarily cover all of the glass surface of the module and can thus delimit so-called dark functional areas. The dark areas are for example arranged centrally or peripherally to the module. They consist for example of transparent areas (glass clear) or opaque such as a decorative enamel, or even mirrors.

Les profilés inférieur 3 et supérieur 3A intégrant chacun le système d'éclairage 2 sont au plus près de la tranche 1A du vitrage (contre pour le profilé inférieur et à une distance d'environ 1 à 2 mm pour le profilé supérieur) afin que les diodes 20 éclairent chaque tranche des feuilles de verre, ou au moins la tranche d'une feuille de verre.The lower 3 and upper 3A profiles each incorporating the lighting system 2 are closer to the slice 1A of the glazing (against for the lower profile and at a distance of about 1 to 2 mm for the upper profile) so that the diodes 20 illuminate each slice of the glass sheets, or at least the slice of a glass sheet.

Chaque profilé 3, 3A présente donc une face dite éclairante en regard de la tranche du vitrage et de préférence plane, et une face opposée plane 31B plaquée contre l'intérieur du dormant.Each profile 3, 3A therefore has a so-called illuminating face facing the edge of the glazing and preferably flat, and an opposite planar face 31B pressed against the inside of the frame.

Pour la partie inférieure de la fenêtre (figure 2), le profilé inférieur 3, intègre le système d'éclairage 2 tout en le protégeant. En outre, il assure la fonction d'appui et de support du vitrage en position montée ; aussi le profilé est-il en contact direct avec la tranche du vitrage.For the lower part of the window ( figure 2 ), the lower profile 3 integrates the lighting system 2 while protecting it. In addition, it performs the function of support and support of the glazing in mounted position; also the profile is in direct contact with the edge of the glazing.

Par ailleurs, dans une fenêtre, il est nécessaire de caler le vitrage dans le dormant. A cet égard, des cales 8 sont prévues sur la périphérie du vitrage et en particulier dans la partie inférieure et supérieure de la fenêtre (figures 2 et 3) en appui contre le dormant et sur lesquelles vient reposer le profilé 3.Moreover, in a window, it is necessary to wedge the glazing in the frame. In this respect, shims 8 are provided on the periphery of the glazing and in particular in the lower and upper part of the window ( figures 2 and 3 ) resting against the frame and on which rests the section 3.

Pour la partie supérieure de la fenêtre (figure 3), le profilé supérieur 3A, n'a pas de fonction de soutien du vitrage et n'a donc pas besoin d'être intimement en contact avec la tranche du vitrage. Comme il sera vu plus loin, la configuration du profilé supérieur peut être simplifiée par rapport à celle du profilé inférieur.For the upper part of the window ( figure 3 ), the upper profile 3A, has no support function of the glazing and therefore does not need to be intimately in contact with the edge of the glazing. As will be seen later, the configuration of the upper profile can be simplified compared to that of the lower profile.

Bien que pour le profilé inférieur 3, tel qu'il sera vu, le profilé est fixé au vitrage, il peut en variante être simplement apposé contre le vitrage. Le vitrage est ainsi posé sur le profilé inférieur.Although for the lower profile 3, as it will be seen, the profile is attached to the glazing, it can alternatively be simply affixed against the glazing. The glazing is thus placed on the lower profile.

De préférence, le profilé 3, respectivement 3A, présente une largeur équivalente à la tranche 1A de l'ensemble du vitrage (épaisseur totale du vitrage) sans dépasser ni recouvrir les faces principales externes 10B et 11B des feuilles de verre.Preferably, the profile 3, respectively 3A, has a width equivalent to the slice 1A of the entire glazing (total thickness of the glazing) without exceeding or covering the main external faces 10B and 11B of the glass sheets.

Le profilé peut s'étendre par une ou deux parties latérales au-delà du bord des faces principales selon une direction orthogonale auxdites faces en restant dans des dimensions appropriées pour le logement du profilé dans le dormant de la fenêtre. Eventuellement, le profilé peut s'étendre par une ou deux parties latérales au-delà du bord des faces principales dans une direction parallèle auxdites faces (en regard des faces), toutefois sur une largeur cantonnée à quelques millimètres afin de ne pas gêner la mise en place de la pareclose et de laisser libre l'espace extérieur séparant lesdites faces de la pareclose pour positionner le joint d'étanchéité 7 de la menuiserie (figures 2 et 3).The profile may extend by one or two lateral portions beyond the edge of the main faces in a direction orthogonal to said faces remaining in appropriate dimensions for the housing of the profile in the frame of the window. Optionally, the profile may extend by one or two lateral parts beyond the edge of the main faces in a direction parallel to said faces (facing the faces), however on a width limited to a few millimeters so as not to interfere with in place of the pareclose and leave free the outer space separating said faces of the pareclose to position the seal 7 of the joinery ( figures 2 and 3 ).

Le profilé 3 ou 3A intégrant le système d'éclairage 2 comporte une base 31 servant à l'assemblage du profilé avec le vitrage et également de support au système d'éclairage 2.The profile 3 or 3A integrating the lighting system 2 comprises a base 31 used for assembling the profile with the glazing and also supporting the lighting system 2.

La base 31 est pleine et de forme allongée et parallélépipédique. Ses deux faces principales opposées sont planes, l'une accueillant le(s) PCB 21 des diodes, et agencée en regard de la tranche du vitrage, tandis que l'autre est en regard du dormant.The base 31 is solid and elongated and parallelepipedic shape. Its two opposite main faces are planar, one hosting the PCB (s) 21 of the diodes, and arranged opposite the edge of the glazing, while the other is opposite the frame.

Plusieurs PCB 21 sont agencés de manière adjacente entre eux le long du profilé.Several PCBs 21 are arranged adjacent each other along the profile.

Les diodes 20 (PCB 21) pourront être assemblées juste avant l'association du profilé au vitrage selon la répartition souhaitée. Les profilés pourront être fabriqués et livrés avec les diodes comme ils pourront être fabriqués avec les cavités appropriées pour loger les diodes ultérieurement.The diodes 20 (PCB 21) can be assembled just before the combination of the profile glazing according to the desired distribution. The profiles can be manufactured and delivered with the diodes as they can be made with cavities suitable for housing the diodes later.

La largeur d'un PCB est inférieure ou égale à la largeur d'une tranche d'une feuille de verre.The width of a PCB is less than or equal to the width of a slice of a glass sheet.

Le profilé inférieur 3 de l'invention doit supporter le poids du vitrage lorsque ce dernier est monté dans la menuiserie. A cet effet (figure 2), il comporte un partie centrale 34 faisant saillie depuis la base 31 en direction du vitrage et deux parois latérales d'extrémité 32 et 33 écartées de la partie centrale 34 et s'étendant orthogonalement depuis respectivement deux bords opposés de la base 31 en direction du vitrage.The lower profile 3 of the invention must support the weight of the glazing when the latter is mounted in the joinery. For this purpose ( figure 2 ), it comprises a central portion 34 protruding from the base 31 towards the glazing and two end side walls 32 and 33 spaced apart from the central portion 34 and extending orthogonally from respectively two opposite edges of the base 31 in the direction glazing.

La partie centrale 34 est destinée à être en contact direct avec le mastic 14 du vitrage agencé entre les deux feuilles de verre, tandis que les parois latérales 32 et 33 sont destinées à être en contact direct avec les tranches 10A et 11A des feuilles de verre.The central portion 34 is intended to be in direct contact with the putty 14 of the glazing arranged between the two sheets of glass, while the side walls 32 and 33 are intended to be in direct contact with the slices 10A and 11A of the glass sheets .

La partie 34 forme une surface pleine en regard du vitrage qui forme une butée d'appui pour le vitrage. Dans une variante non illustrée, indépendamment de la configuration du profilé, l'ensemble de l'invention comporte une pièce posée entre le profilé et le vitrage et dont la surface en regard du vitrage forme une butée d'appui.The portion 34 forms a solid surface facing the glazing which forms a bearing abutment for the glazing. In a non-illustrated variant, regardless of the configuration of the profile, the assembly of the invention comprises a piece placed between the profile and the glazing and whose surface facing the glazing forms a bearing abutment.

La partie centrale 34 et les parois latérales 32 et 33 présentent chacune une hauteur (dimension orthogonale aux faces principales de la base 31) supérieure à la hauteur du PCB 21 et des diodes 20, de façon à faire saillie au-delà de la surface d'extrémité distale éclairante des diodes (environ de 2 mm).The central portion 34 and the side walls 32 and 33 each have a height (dimension orthogonal to the main faces of the base 31) greater than the height of the PCB 21 and the diodes 20, so as to make protruding beyond the illuminating distal end surface of the diodes (about 2 mm).

Les surfaces d'extrémité libre de la partie centrale 34 et des parois 32 et 33, opposées à la base, sont coplanaires et servent de surfaces d'appui à l'ensemble de la tranche 1A du vitrage.The free end surfaces of the central portion 34 and the walls 32 and 33, opposite to the base, are coplanar and serve as bearing surfaces to the entire portion 1A of the glazing.

En outre, la partie centrale 34 et les parois latérales 32 et 33 délimitent deux cavités 32A et 33A dans lesquelles sont logées les diodes 20, et constituent des moyens de protection pour celles-ci qui ne risquent pas d'être endommagées par le poids du vitrage.In addition, the central portion 34 and the side walls 32 and 33 delimit two cavities 32A and 33A in which the diodes 20 are housed, and constitute means of protection for these which are not likely to be damaged by the weight of the glazing.

De préférence, le profilé inférieur 3 est fait de plusieurs éléments, la base 31 constituant au moins un élément à elle seule, tandis que la partie centrale 34 et les parois latérales 32 et 33 forment un second élément monobloc. Cette configuration sera décrite plus loin.Preferably, the lower profile 3 is made of several elements, the base 31 constituting at least one element alone, while the central portion 34 and the side walls 32 and 33 form a second one-piece element. This configuration will be described later.

L'assemblage du profilé inférieur 3 au vitrage est réalisé via des moyens de fixation amovibles, de préférence par des vis 9 (figure 2) qui d'une part traversent la base 31 et la partie centrale 34 via un alésage traversant 38, et d'autre part sont introduites dans le mastic 14.The assembly of the lower profile 3 to the glazing is achieved via removable fastening means, preferably by screws 9 ( figure 2 ) which on the one hand pass through the base 31 and the central portion 34 via a through bore 38, and on the other hand are introduced into the putty 14.

Avantageusement, l'alésage 38 constitue un moyen de guidage pour positionner idéalement le profilé contre la tranche du vitrage afin qu'il soit correctement centré vis-à-vis de cette tranche pour procurer un appui équilibré du vitrage sur le profilé, et agencer correctement le système d'éclairage en regard des feuilles de verre.Advantageously, the bore 38 constitutes a guiding means to ideally position the profile against the edge of the glazing so that it is correctly centered with respect to this slice to provide a balanced support of the glazing on the profile, and to arrange correctly the lighting system facing the glass sheets.

Comme déjà vu, le profilé inférieur pourrait être simplement plaque contre le vitrage, sans fixation par vis 9. Cette variante n'est pas illustrée.As already seen, the lower profile could be simply plate against the glazing, without fixing screw 9. This variant is not illustrated.

Le profilé 3, illustré en vue de dessus sur la figure 4, comporte plusieurs alésages 38 répartis centralement le long du profilé 3 et dans lesquels sont destinées à coopérer des vis du type 9 pour assembler le profilé selon la totalité du bord inférieur du vitrage.The profile 3, illustrated in plan view on the figure 4 , comprises several bores 38 distributed centrally along the profile 3 and in which are intended to cooperate type 9 screws to assemble the profile along the entire lower edge of the glazing.

De préférence, pour faciliter la mise en place des vis, le mastic 14 comprend des alésages 14A adaptés à recevoir des inserts du type chevilles pour le vissage des corps de vis 9. Les alésages sont réalisés lors de la fabrication du vitrage, au moment du dépôt du mastic qui est alors mou.Preferably, to facilitate the insertion of the screws, the putty 14 comprises bores 14A adapted to receive inserts of the anchor type for screwing the screw bodies 9. The bores are made during the manufacture of the glazing, at the time of putty deposit which is then soft.

Les vis 9 traverse la totalité de l'épaisseur du profilé depuis la face de la base 31 en regard du dormant et au-delà de la face opposé du profilé formée par les surfaces d'extrémité de la partie centrale 34 et des parois latérales 32 et 33.The screws 9 cross the entire thickness of the profile from the face of the base 31 facing the frame and beyond the opposite face of the profile formed by the end surfaces of the central portion 34 and the side walls 32 and 33.

Afin que la face 31B du profilé en regard et apposée contre le dormant puisse être appuyée de manière plane contre le dormant, les têtes de vis 9, de préférences plates, ne font pas saillie hors du profilé, la face 31B présentant avantageusement un lamage pour le logement de la tête de vis.So that the face 31B of the profile facing and affixed against the frame can be pressed flat against the frame, the screw heads 9, preferably flat, do not protrude from the profile, the face 31B advantageously having a countersink for the housing of the screw head.

En variante, la fixation amovible du profilé au vitrage peut être réalisée par collage amovible avec de l'adhésif double-face. Toutefois, la fixation par des moyens mécaniques (clou, vis, etc..) sera plus solide et pérenne dans le temps et assurera de démonter aisément le profilé ultérieurement pour changer les PCB porteurs des diodes sans les endommager.Alternatively, the removable attachment of the profile to the glazing can be achieved by removable bonding with double-sided adhesive. However, the fixing by mechanical means (nail, screw, etc. ..) will be more solid and durable over time and will ensure easy to remove the profile later to change the carrier PCB diodes without damaging them.

En regard de la figure 3, le profilé supérieur 3A n'a pas forcément besoin de partie centrale et parois latérales car il ne supporte aucunement le poids du vitrage. Il peut être constitué de la seule base 31. En revanche, il est nécessaire pour ne pas endommager les diodes que la surface éclairante d'extrémité de celles-ci ne soit pas accolée contre les feuilles de verre mais distantes d'au moins 1 voire 2 mm. A cette fin, s'il n'y a pas les parois latérales qui forment entretoises, la profondeur de l'alésage 14A ou de l'insert dans le mastic d'étanchéité 14 est adapté pour que le serrage maximale par vis autorise cette distance intercalaire des diodes avec les feuilles de verre.With regard to the figure 3 , the upper profile 3A does not necessarily need the central part and side walls because it does not support the weight of the glazing. It may consist of the single base 31. On the other hand, it is necessary not to damage the diodes that the end illuminating surface thereof is not contiguous against the glass sheets but at least 1 distant distant even 2 mm. To this end, if there are no side walls forming spacers, the depth of the bore 14A or the insert in the sealing mastic 14 is adapted so that the maximum tightening screw allows this distance interlayer diodes with glass sheets.

Dans le mode préféré du profilé inférieur 3 de l'invention, celui-ci est fait de plusieurs éléments, la base 31 constituant au moins un élément à elle seule, tandis que la partie centrale 34 et les parois latérales 32 et 33 forment un second élément monobloc.In the preferred embodiment of the lower profile 3 of the invention, this is made of several elements, the base 31 constituting at least one element alone, while the central portion 34 and the side walls 32 and 33 form a second monoblock element.

En regard de la figure 5, le second élément monobloc (partie centrale 34 et les parois latérales 32 et 33) forme un capot longitudinal 31A qui présente deux cavités longitudinales 32A et 33A délimitées par la partie centrale pleine 34 et respectivement les deux parois latérales 32 et 33.With regard to the figure 5 , the second one-piece element (central portion 34 and the side walls 32 and 33) forms a longitudinal cover 31A which has two longitudinal cavities 32A and 33A delimited by the solid central portion 34 and respectively the two side walls 32 and 33.

Le capot 31A est destiné à être rapporté contre la base 31 après pose voire fixation du ou des PCB 21 des diodes sur ladite base 31. La fixation des PCB est soit amovible (par vis), soit est solidaire de manière pérenne. Lorsqu'il s'agit de changer les diodes au cours de l'utilisation du vitrage, soit il sera changé les PCB 21 qui sont amovibles, soit il sera changé la base 31 portant les PCB.The cover 31A is intended to be mounted against the base 31 after installation or fixation of the PCB or 21 of the diodes on said base 31. The attachment of the PCB is either removable (by screw) or is permanently secured. When it comes to changing the diodes during the use of the glazing, either it will be changed the PCB 21 which are removable, or it will be changed the base 31 carrying PCBs.

Les cavités longitudinales 32A et 33A du capot fournissent des logements aux diodes, les PCB 21 reposant sur la base 31 à distance de la face supérieure du capot.The longitudinal cavities 32A and 33A of the cover provide housing for the diodes, the PCBs 21 resting on the base 31 away from the upper face of the cover.

La figure 4 qui illustre en vue de dessus le profilé inférieur 3, montre le capot 31A rapporté sur la base 31 pourvu des diodes 20.The figure 4 which illustrates in plan view the lower profile 3, shows the cover 31A attached to the base 31 provided with the diodes 20.

Le capot 31A présente donc ses cavités en regard de la base 31, tandis qu'il est destiné à présenter son face fermée opposée 35 en regard du vitrage. Toutefois, il présente dans l'épaisseur de sa face fermée 35, des orifices 36 qui sont destinés à être en regard des diodes, permettant ainsi à la lumière des diodes de s'échapper du profilé 31 qui est dirigée vers vers la tranche du vitrage.The cover 31A therefore has its cavities facing the base 31, while it is intended to present its opposite closed face 35 facing the glazing. However, it has, in the thickness of its closed face 35, orifices 36 which are intended to face the diodes, thus allowing the light of the diodes to escape from the profile 31 which is directed towards the edge of the glazing. .

Le capot 31A est fixé à la base 31 de préférence via des vis 37A au travers d'alésages 37 qui traversent l'épaisseur de la partie centrale 34 et de la base 31. La figure 6, qui est une vue en coupe selon B-B de la figure 4, montre la fixation du capot 31A sur la base 31.The cover 31A is fixed to the base 31 preferably via screws 37A through holes 37 which pass through the thickness of the central portion 34 and the base 31. figure 6 which is a sectional view along BB of the figure 4 shows the fixing of the cover 31A on the base 31.

Le profilé 3 forme ainsi avec sa base 31 et son capot 31A un boitier de protection emprisonnant les PCB 21 et les diodes 20 dont la lumière est extraite grâce aux orifices 36 (figures 4 et 5).The section 3 thus forms with its base 31 and its cover 31A a protective box enclosing the PCBs 21 and the diodes 20 whose light is extracted through the orifices 36 (FIG. figures 4 and 5 ).

La base 31 et son capot troué 31A sont parallèles à la tranche 1A du vitrage afin de l'éclairer, la tranche 1A étant plane et de préférence non biseautée.The base 31 and its perforated cover 31A are parallel to the slice 1A of the glazing to illuminate it, the slice 1A being flat and preferably not beveled.

La face fermée 35 du capot dotée des orifices 36 peut être en contact direct avec la tranche 1A du verre et supporter le vitrage, tel qu'illustré sur la figure 2 sans risquer d'endommager les diodes.The closed face 35 of the cover provided with the orifices 36 can be in direct contact with the slice 1A of the glass and support the glazing, as illustrated in FIG. figure 2 without risk of damaging the diodes.

Les orifices 36 du capot peuvent être limités à la grosseur de chaque diode 20, selon par exemple une forme circulaire. Ils peuvent être également de forme oblongue en regard d'un groupe de diodes 20, tels qu'illustrés sur la figure 7.The orifices 36 of the cover may be limited to the size of each diode 20, for example according to a circular shape. They may also be oblong in relation to a group of diodes 20, as illustrated in FIG. figure 7 .

Selon l'invention, le profilé 3, respectivement 3A intègre des moyens de dissipation de la chaleur, en particulier à base d'un matériau métallique notamment en inox, en aluminium.According to the invention, the profile 3, respectively 3A incorporates heat dissipation means, in particular based on a metallic material, in particular stainless steel, aluminum.

Les moyens de dissipation de la chaleur sont au moins solidaires des PCB 21 support des diodes. Cela permet de dissiper la chaleur émise par les diodes au niveau de leur connexion aux PCBThe heat dissipation means are at least integral with the PCBs 21 supporting the diodes. This helps dissipate the heat emitted by the diodes at their PCB connection

De préférence, la base 31 porteuse du ou des supports PCB (eux-mêmes métalliques ou non) forment ces moyens de dissipation de la chaleur.Preferably, the base 31 carrying the PCB support (s) (themselves metallic or not) form these means of dissipation of heat.

Selon l'invention, le profilé est conçu pour éviter tout pont thermique avec le vitrage, en particulier aucune partie métallique du profilé n'est à la fois en contact avec les deux feuilles de verre. Ainsi plusieurs variantes de réalisation du profilé sont envisagées, et ici illustrées sans être exhaustives, pour le profilé inférieur et le profilé supérieur.According to the invention, the profile is designed to avoid any thermal bridge with the glazing, in particular no metal part of the profile is both in contact with the two sheets of glass. Thus several variants of the profile are envisaged, and here illustrated without being exhaustive, for the lower profile and the upper profile.

Dans le mode de réalisation préféré du profilé inférieur 3, celui-ci est fait de plusieurs éléments comme vu plus haut, de la base 31 et des parois latérales 32 et 33 et paroi centrale 34. La base 31 est métallique tandis que les parois latérales 32 et 33 qui sont reliées entre elles sont faites d'un matériau plastique, ou du moins d'un matériau non conducteur thermique.In the preferred embodiment of the lower profile 3, it is made of several elements as seen above, the base 31 and the side walls 32 and 33 and central wall 34. The base 31 is metal while the side walls 32 and 33 which are interconnected are made of a plastic material, or at least a non-conductive thermal material.

Dans des variantes de réalisation illustrées sur la figure 8 à 10 adaptées exclusivement à un profilé supérieur 3A, le profilé est fait de la seule base 31 qui est métallique et est directement fixée au mastic 14.In variant embodiments illustrated on the figure 8 to 10 adapted exclusively to an upper profile 3A, the profile is made of the only base 31 which is metallic and is directly attached to the mastic 14.

Sur la figure 8, la base 31 s'étend sur toute la longueur de la tranche du vitrage et présente une âme 31D fixée au mastic par des moyens de fixation 31H du type collage et deux ailes latérales 31E et 31F et en saillie de l'âme à section en U retourné. Des moyens intercalaires isolants thermiquement 31G sont agencés entre les parois latérales d'extrémité des ailes 31E et 31F et les tranches respectives 10A et 11A des feuilles de verre, évitant tout pont thermique.On the figure 8 , the base 31 extends over the entire length of the wafer of the glazing unit and has a core 31D fixed to the sealant by fastening means 31H of the bonding type and two lateral wings 31E and 31F and projecting from the section core. U returned. Thermally insulating spacer means 31G are arranged between the end side walls of the wings 31E and 31F and the respective slices 10A and 11A of the glass sheets, avoiding any thermal bridge.

La figure 9 illustre le même type de profilé que celui de la figure 8. Le profilé peut être ou non fixé au mastic 14 du vitrage. La figure montre en revanche que le profilé est associé à une cale 8 par collage 31J.The figure 9 illustrates the same type of profile as that of the figure 8 . The profile may or may not be attached to the mastic 14 of the glazing. The figure shows however that the profile is associated with a shim 8 by gluing 31J.

La figure 10 illustre encore une autre variante de profilé. Le profilé comporte une partie centrale en contact avec le mastic et ne présente pas de retour en contact avec les feuilles de verre. La partie centrale est fixée contre le mastic 14 par vis, la tête de vis opposée au mastic ne dépassant pas du profilé car celui-ci pourra ainsi garder une surface plane qui sera apposée contre une cale (cale ici non illustrée).The figure 10 illustrates yet another variant of profile. The profile has a central portion in contact with the sealant and does not return back in contact with the glass sheets. The central portion is fixed against the mastic 14 by screw, the screw head opposite the mastic not exceeding the profile because it can thus keep a flat surface that will be affixed against a shim (wedge here not shown).

Les figures 11a à 13c illustrent plusieurs variantes de profilé 3 pour lesquels les moyens de dissipation de la chaleur des diodes ne sont pas constitués par la base 31 telle que vue plus haut mais par des moyens rapportés.The Figures 11a to 13c illustrate several variants of section 3 for which the heat dissipation means of the diodes are not constituted by the base 31 as seen above but by means reported.

La variante des figures 11a et 11b propose une plaque métallique 5 logée dans le fond des cavités 32A et 33A sur laquelle repose les PCB 21, la base 31, la partie centrale 34 et les parois latérales 32 et 33 formant un ensemble monobloc en matière plastique.The variant of Figures 11a and 11b proposes a metal plate 5 housed in the bottom of the cavities 32A and 33A on which the PCBs 21, the base 31, the central portion 34 and the side walls 32 and 33 forming a one-piece assembly of plastics material.

La variante des figures 12a et 12b propose un élément métallique 5 qui forme une plaque en fond de cavités 32A, respectivement 33A, sur laquelle repose les PCB 21, et la paroi latérale 32, respectivement 33 du profilé, le reste du profilé (base 31 et paroi centrale 34) étant en matière plastique.The variant of Figures 12a and 12b proposes a metal element 5 which forms a plate at the bottom of cavities 32A, respectively 33A, on which rests the PCBs 21, and the side wall 32, respectively 33 of the profile, the rest of the profile (base 31 and central wall 34) being in plastic material.

Dans les deux variantes ci-dessus, les orifices 36 de la face supérieure du profilé présentent une largeur limitée à la largeur des têtes des diodes.In the two variants above, the orifices 36 of the upper face of the profile have a width limited to the width of the heads of the diodes.

La variante des figures 13a et 13b correspond à la variante des figures 12a et 12b, la différence consistant en la largeur des orifices 36 qui correspond à la largeur des PCB 21. En outre les orifices sont de forme rectangulaire pour un ensemble de diodes. En variante sur la vue de dessus de la figure 13c, les orifices 36 sont de forme circulaire.The variant of Figures 13a and 13b corresponds to the variant of Figures 12a and 12b , the difference being the width of the orifices 36 which corresponds to the width of the PCB 21. In addition, the orifices are of rectangular shape for a set of diodes. Alternatively on the top view of the figure 13c , the orifices 36 are of circular shape.

A titre d'exemple, les dimensions suivantes sont données :

  • Largeur du PCB : 10 mm ou 5 mm,
  • Largeur de la base 31 : 12 à 15 mm pour un PCB de 10 mm de large,
  • Taille des diodes : 3,5 mm par 3,5 mm ,
  • Hauteur du profilé entre la face 31B et la face 35 : 8 mm
By way of example, the following dimensions are given:
  • PCB width: 10 mm or 5 mm,
  • Width of the base 31: 12 to 15 mm for a PCB 10 mm wide,
  • Size of the diodes: 3.5 mm by 3.5 mm,
  • Profile height between face 31B and face 35: 8 mm

Ainsi, le vitrage multiple de l'invention fournit un éclairage à partir d'un système d'éclairage associé mais extérieur au vitrage et tel qu'il puisse être aisément remplacé en étant contenu dans au moins un profilé assemblé à la tranche du vitrage de manière démontable.Thus, the multiple glazing unit of the invention provides lighting from an associated lighting system but outside the glazing and such that it can easily be replaced by being contained in at least one section assembled to the edge of the glazing unit. demountable way.
