Description

La présente invention est du domaine de l'éclairage et concerne plus particulièrement une rampe d'éclairage.The present invention is in the field of lighting and relates more particularly to a light bar.

La déposante a déjà développé une rampe d'alimentation électrique décrite dans la demande de brevet européen EP-0.375.623 qui concerne une rampe d'éclairage présentant une succession de paires de contacts électriques comportant au moins deux bandes conductrices superposées ayant à des distances prédéterminées des plaquettes disposées à 90° pour alimenter des séries d'ampoules disposées entre deux contacts adjacents. Les bandes conductrices sont chacune recouvertes par un corps isolant continu disposé tout au long d'au moins une de leurs faces, de manière à former un empilage dans lequel les bandes conductrices sont totalement isolées entre elles et vers l'extérieur, à l'exclusion des plaquettes de contact.The applicant has already developed an electrical supply ramp described in European patent application EP-0.375.623 which relates to a lighting ramp having a succession of pairs of electrical contacts comprising at least two superimposed conductive strips having at predetermined distances plates arranged at 90 ° to supply series of bulbs arranged between two adjacent contacts. The conductive strips are each covered by a continuous insulating body disposed along at least one of their faces, so as to form a stack in which the conductive strips are completely isolated from each other and towards the outside, excluding contact pads.

Dans sa demande de brevet européen EP-0.516.578, la déposante propose que les bandes conductrices soient glissées dans un profilé présentant un dégagement central pour les bandes conductrices et une ouverture laissant passer librement les plaquettes de contact.In its European patent application EP-0.516.578, the applicant proposes that the conductive strips be slid into a profile having a central clearance for the conductive strips and an opening allowing the contact pads to pass freely.

La présente invention concerne une amélioration destinée plus particulièrement à l'éclairage des grandes surfaces de façades ou de plafonds, et permet de disposer les rampes soit longitudinalement, soit transversalement selon l'effet esthétique désiré.The present invention relates to an improvement intended more particularly for lighting large surfaces of facades or ceilings, and makes it possible to arrange the ramps either longitudinally or transversely according to the desired aesthetic effect.

La rampe selon l'invention comprend un profilé muni de moyens de fixation et apte à recevoir en son intérieur au moins deux bandes conductrices (30;31,32) présentant une succession de plaquettes (33,34) placées à des distances prédéterminées de manière à former des paires de contacts électriques alimentant une succession d'ampoules (50) disposées tout au long de la rampe entre deux contacts adjacents.The ramp according to the invention comprises a profile provided with fixing means and capable of receiving inside it at least two conductive strips (30; 31,32) having a succession of plates (33,34) placed at predetermined distances so forming pairs of electrical contacts supplying a succession of bulbs (50) arranged along the ramp between two adjacent contacts.

Elle est caractérisée par :

  • une bande réfléchissante de section parabolique, disposée de manière continue à l'intérieur du profilé dans le sens de sa longueur et traversée par les plaquettes des contacts électriques, de manière à ce que le foyer de la section parabolique soit disposé au voisinage du centre des ampoules, de manière à constituer un réflecteur linéaire distribuant un faisceau lumineux étroit tout au long de ladite rampe, et
  • au moins une grille de diffusion disposée dans ledit faisceau lumineux et apte à le diriger et le réfléchir selon une direction préférentielle.
It is characterized by:
  • a reflective strip of parabolic section, arranged continuously inside the profile in the direction of its length and traversed by the plates of the electrical contacts, so that the focal point of the parabolic section is disposed in the vicinity of the center of the bulbs, so as to constitute a linear reflector distributing a narrow light beam along said ramp, and
  • at least one diffusion grid disposed in said light beam and capable of directing and reflecting it in a preferred direction.

L'invention s'étend en outre à une utilisation de plusieurs rampes pour l'éclairage de grandes surfaces, caractérisée en ce que l'on dispose les rampes bout à bout de telle manière que le faisceau lumineux soit sensiblement parallèle à ladite surface pour l'éclairer uniformément.The invention further extends to the use of several ramps for lighting large areas, characterized in that the ramps are placed end to end in such a way that the light beam is substantially parallel to said surface for the '' light evenly.

Le dessin annexé représente, à titre d'exemple non limitatif, une forme d'exécution de l'objet de la présente invention.The appended drawing represents, by way of nonlimiting example, an embodiment of the object of the present invention.

La figure 1 est une représentation éclatée, vue en perspective, de fragments des principaux composants d'une rampe d'éclairage.Figure 1 is an exploded view, in perspective, of fragments of the main components of a light bar.

La figure 2 est une coupe transversale d'une rampe d'éclairage montée, montrant un système de fixation à une paroi.Figure 2 is a cross section of a mounted light bar, showing a system for fixing to a wall.

La figure 3 est une vue de dessus ainsi qu'une représentation en coupe longitudinale d'une variante de grille de diffusion.Figure 3 is a top view and a longitudinal sectional representation of a variant of the diffusion grid.

La figure 4 est une coupe longitudinale selon la ligne IV-IV de la rampe de la figure 2, avec deux types de grilles de diffusion.Figure 4 is a longitudinal section along the line IV-IV of the ramp of Figure 2, with two types of diffusion grids.

Dans la représentation générale de la figure 1 on a représenté le rail de fixation 10, destiné à l'accrochage de la rampe selon l'invention sur une paroi 11. Comme on le verra par la suite, le rail de fixation 10 est fixé horizontalement ou verticalement sur la paroi, et peut également être disposé selon toute position angulaire intermédiaire (pour l'éclairage d'un fronton par exemple).In the general representation of Figure 1 there is shown the fixing rail 10, for hooking the ramp according to the invention on a wall 11. As will be seen later, the fixing rail 10 is fixed horizontally or vertically on the wall, and can also be arranged in any intermediate angular position (for lighting a pediment for example).

Le rail de fixation 10 permet l'accrochage du profilé constituant le boîtier 20, destiné à recevoir des bandes conductrices 30, un réflecteur 40, des ampoules 50, une grille de diffusion 60 et un verre de protection 70. On a schématisé l'alimentation en courant par un ensemble de connexion 80. En outre, les deux extrémités de l'ensemble décrit reçoivent un embout 90.The fixing rail 10 allows the attachment of the profile constituting the housing 20, intended to receive conductive strips 30, a reflector 40, bulbs 50, a diffusion grid 60 and a protective glass 70. The power supply is shown diagrammatically by running through a connection assembly 80. In addition, the two ends of the described assembly receive a nozzle 90.

Dans le cas décrit d'une rampe d'éclairage mural, le rail de fixation 10 sera fixé à la paroi 11 de manière connue. Lors de la première mise en place, on veillera à positionner ce rail 10 de manière à obtenir un éclairement optimum de la paroi. On pourra à cette fin utiliser un support inclinable, permettant d'incliner le rail par rapport à la surface à éclairer. En outre on pourra choisir de disposer le rail à une certaine distance de la paroi, en utilisant des supports réglables connus de l'homme du métier.In the described case of a wall lighting ramp, the fixing rail 10 will be fixed to the wall 11 in a known manner. During the first installation, care will be taken to position this rail 10 so as to obtain optimum illumination of the wall. To this end, a tilting support can be used, making it possible to tilt the rail relative to the surface to be lit. In addition, it will be possible to choose to arrange the rail at a certain distance from the wall, using adjustable supports known to those skilled in the art.

Le rail de fixation 10 comporte une ouverture longitudinale 12, destinée au passage des éléments électriques de connexion 80. Extérieurement, le rail 10 présente une enveloppe parallélipipédique 13 et comporte sur une face un dégagement longitudinal 14 et une creusure arrondie 15, dont l'utilité seront mentionnées plus loin. On a représenté au dessin un seul dégagement longitudinal 14, mais il est plus simple de réaliser deux dégagements 14 sur les faces opposées du rail, pour pouvoir utiliser ce dernier dans un sens comme dans l'autre.The fixing rail 10 has a longitudinal opening 12, intended for the passage of the electrical connection elements 80. Externally, the rail 10 has a rectangular casing 13 and has on one side a longitudinal clearance 14 and a rounded recess 15, the utility of which will be mentioned later. There is shown in the drawing a single longitudinal clearance 14, but it is simpler to make two clearances 14 on the opposite faces of the rail, in order to be able to use the latter in one direction as in the other.

Le boîtier 20 est constitué par un profilé présentant une section d'une quinzaine de centimètres carrés et débité en longueurs de l'ordre de un à quelques mètres en fonction des utilisations prévues.The housing 20 consists of a section having a section of about fifteen square centimeters and cut into lengths of the order of one to a few meters depending on the intended uses.

Ce profilé 20 comporte des ouvertures longitudinales 21 et 22 sur deux de ses faces. L'ouverture 21 permet le passage du faisceau lumineux tandis que l'ouverture 22 est munie des moyens de fixation au rail 10.This profile 20 has longitudinal openings 21 and 22 on two of its faces. The opening 21 allows the passage of the light beam while the opening 22 is provided with means for fixing to the rail 10.

L'ouverture 21 est bordée par deux ailes latérales 23 et 24, munies chacune d'une série de rainures longitudinales 25 se faisant face. L'aile 23 sera disposée face à la surface à éclairer tandis que l'aile 24 constitue la partie la plus en saillie par rapport à la paroi 11. Le fond de l'ouverture 21 comporte un rail central 26.The opening 21 is bordered by two lateral wings 23 and 24, each provided with a series of longitudinal grooves 25 facing each other. The wing 23 will be disposed facing the surface to be lit while the wing 24 constitutes the most projecting part relative to the wall 11. The bottom of the opening 21 comprises a central rail 26.

L'ouverture 22 est de forme correspondante à celle du rail 10 et chacune de ses parois est munie d'un jonc 27 destiné à coopérer avec le dégagement 14 et la creusure 15 lorsque le boîtier 20 est disposé sur le rail de fixation 10. On notera encore la présence d'une paroi intermédiaire 28, destinée à créer un dégagement pour recevoir les fils électriques d'alimentation 80 qui traversent cette paroi par une ouverture 29.The opening 22 is of shape corresponding to that of the rail 10 and each of its walls is provided with a rod 27 intended to cooperate with the clearance 14 and the recess 15 when the housing 20 is disposed on the fixing rail 10. On note also the presence of an intermediate wall 28, intended to create a clearance for receiving the electrical supply wires 80 which pass through this wall through an opening 29.

Le rail 10 et le profilé 20 sont de préférence en aluminium. Le profilé 20 subit en outre un traitement de surface lui conférant une couche isolante. Ce traitement est par exemple déposé par anodisation ou électrodéposition, pour obtenir à la fois l'isolation et un aspect esthétique dont la couleur coïncide avec le mur à éclairer.The rail 10 and the profile 20 are preferably made of aluminum. The profile 20 also undergoes a surface treatment giving it an insulating layer. This treatment is, for example, deposited by anodization or electrodeposition, to obtain both insulation and an aesthetic appearance whose color coincides with the wall to be lit.

Les bandes conductrices 30 sont constituées par deux bande 31 et 32, chacune munie, à intervalles réguliers, de plaquettes 33 et 34 repliées à 90°. En outre au moins l'une des bandes comporte des dégagements 35 pour le passage de la plaquette 33 de l'autre bande. Les bandes conductrices 31 et 32 sont de préférence en laiton et sont revêtues d'une couche isolante, à l'exception de la partie extrême des plaquettes 33 et 34. Cette couche isolante est, de manière connue, appliquée par poudrage électrostatique.The conductive strips 30 consist of two strips 31 and 32, each provided, at regular intervals, with plates 33 and 34 folded at 90 °. In addition at least one of the strips has clearances 35 for the passage of the plate 33 of the other strip. The conductive strips 31 and 32 are preferably made of brass and are coated with an insulating layer, with the exception of the end part of the plates 33 and 34. This insulating layer is, in known manner, applied by electrostatic powdering.

Le réflecteur 40 est constitué par une bande présentant une partie centrale 41 de section parabolique, prolongée par deux ailes latérales 42 destinées à s'engager dans une des paires de rainures longitudinales 25 du boîtier 20. La courbure parabolique de la partie centrale 41 sera déterminée en fonction de la distance aux lampes 50 d'une part, et de la forme du faisceau lumineux désiré d'autre part. La partie centrale 41 présente une succession d'ouvertures 43 pour le passage des plaquettes 33 et 34. De préférence le réflecteur 40 est constitué par une bande métallique dont l'une des faces est lissée pour obtenir une réflexion maximale. Pour éviter tout contact entre le réflecteur 40 et les plaquettes 33 et 34, on disposera avantageusement des plots isolants 44, dont un seul est représenté à la figure 1, dans l'un des passages 43. On notera finalement que la forme de la paroi intermédiaire 28 épouse sensiblement celle du réflecteur 40.The reflector 40 consists of a strip having a central part 41 of parabolic section, extended by two lateral wings 42 intended to engage in one of the pairs of longitudinal grooves 25 of the housing 20. The parabolic curvature of the central part 41 will be determined as a function of the distance from the lamps 50 on the one hand, and of the shape of the desired light beam on the other hand. The central part 41 has a succession of openings 43 for the passage of plates 33 and 34. Preferably the reflector 40 is constituted by a metal strip, one of the faces of which is smoothed to obtain maximum reflection. To avoid any contact between the reflector 40 and the plates 33 and 34, there will advantageously be insulating pads 44, only one of which is shown in FIG. 1, in one of the passages 43. It will finally be noted that the shape of the wall intermediate 28 substantially matches that of reflector 40.

Les ampoules 50 sont constituées par des ampoules navettes ou des lampes Xenon, dont les extrémités sont destinées à coopérer avec les plaquettes 33 et 34.The bulbs 50 are constituted by shuttle bulbs or Xenon lamps, the ends of which are intended to cooperate with the plates 33 and 34.

Pour cacher les ampoules 50, on prévoit une grille de diffusion 60 constituée par une bande 61 comportant des bords 62 destinés à s'engager dans l'une des paires de rainures longitudinales 25 du boîtier 20, ainsi que des ailettes 63 repliées à 90°. Cette grille est obtenue par exemple dans une bande 61 d'aluminium dont l'une des faces est noircie et l'autre face est réfléchissante. La bande est découpée pour former les ailettes 63 par emboutissage. Les faces noircies sont disposées vers l'extérieur de la paroi, pour éviter toute réflexion vers l'extérieur.To hide the bulbs 50, a diffusion grid 60 is provided, consisting of a strip 61 having edges 62 intended to engage in one of the pairs of longitudinal grooves 25 of the housing 20, as well as fins 63 folded at 90 °. This grid is obtained for example in an aluminum strip 61 of which one of the faces is blackened and the other face is reflective. The strip is cut to form the fins 63 by stamping. The blackened faces are arranged towards the outside of the wall, to avoid any reflection towards the outside.

La rampe d'éclairage mural selon l'invention étant plus particulièrement étudiée pour l'extérieur, on disposera encore un verre de protection 70 dans la paire extérieure de rainures longitudinales 25 du boîtier 20.Since the wall light bar according to the invention is more particularly studied for the exterior, there will also be a protective glass 70 in the outer pair of longitudinal grooves 25 of the housing 20.

L'ensemble de connexion 80 est constitué par un fil d'alimentation 81 relié d'une part à un connecteur femelle 82 destiné à coopérer avec l'une des plaquettes d'alimentation 33 ou 34 et d'autre part un connecteur mâle 83 d'alimentation.The connection assembly 80 is constituted by a supply wire 81 connected on the one hand to a female connector 82 intended to cooperate with one of the supply plates 33 or 34 and on the other hand a male connector 83 d 'food.

L'embout 90 est constitué par une surface plane 91 de forme correspondant à celle du profilé 20; on prévoira avantageusement de pouvoir détacher le bord 92 correspondant au rail 10, le long d'une ligne 93. On pourra ainsi juxtaposer plusieurs lampes d'éclairage selon l'invention le long d'un rail unique. Chaque embout comporte vers l'intérieur deux pieds 94 destinés à s'engager de part et d'autre de la partie centrale 21 du profilé 20. L'embout de fermeture 90 est de préférence moulé en matière plastique.The end piece 90 is constituted by a flat surface 91 of shape corresponding to that of the profile 20; advantageously provision will be made to be able to detach the edge 92 corresponding to the rail 10, along a line 93. It will thus be possible to juxtapose several lighting lamps according to the invention along a single rail. Each end piece has inwardly two feet 94 intended to engage on either side of the central part 21 of the profile 20. The closure end piece 90 is preferably molded in plastic.

L'ensemble selon l'invention est représenté monté à la figure 2 à une échelle agrandie. On retrouve le rail de fixation 10 pour l'accrochage du profilé constituant le boîtier 20, les bandes conductrices 30, le réflecteur 40, une ampoule navette 50, une grille de diffusion 60 et le verre de protection 70 de l'ensemble. On notera que les joncs 27 des deux prolongements parallèles 26 viennent coopérer d'une part avec la creusure arrondie 15 du rail 10 et d'autre part avec le dégagement 14. Ainsi, une fois que le rail 10 est fixé à la paroi à éclairer dans une position optimale, on peut poser et déposer aisément le boîtier 20 qui vient s'encliqueter sur le rail grâce aux formes arrondies des joncs 27, par exemple pour changer les ampoules.The assembly according to the invention is shown mounted in Figure 2 on an enlarged scale. We find the fixing rail 10 for the attachment of the profile constituting the housing 20, the conductive strips 30, the reflector 40, a shuttle bulb 50, a diffusion grid 60 and the protective glass 70 of the assembly. It will be noted that the rods 27 of the two parallel extensions 26 cooperate on the one hand with the rounded recess 15 of the rail 10 and on the other hand with the clearance 14. Thus, once the rail 10 is fixed to the wall to be lit in an optimal position, the housing 20 which can be snapped onto the rail can be easily installed and removed thanks to the rounded shapes of the rods 27, for example to change the bulbs.

On voit également à la figure 2 comment l'ensemble des bandes conductrices et du réflecteur sont glissés dans les paires de rainures longitudinales 25, de même que les grilles 60 et le verre de protection 70.FIG. 2 also shows how all of the conductive strips and the reflector are slid into the pairs of longitudinal grooves 25, as are the grids 60 and the protective glass 70.

On notera à la figure 2 que l'on a représenté deux grilles 60 superposées, afin d'augmenter le nombre des ailettes 63 tout en leur laissant une hauteur suffisante pour que les ampoules ne soient pas visibles dès que l'on se trouve à une certaine distance de la paroi.It will be noted in FIG. 2 that two superimposed grids 60 have been shown, in order to increase the number of fins 63 while leaving them a sufficient height so that the bulbs are not visible as soon as one is at a some distance from the wall.

Dans la vue de variante de grilles de la figure 3 on a représenté :

A :
une région de bande découpée pour créer des formes rectangulaires 64 transversales par rapport à la bande, tout en conservant les bords 62,
B :
une région de cette même bande où les ailettes rectangulaires 64 sont repliées à 90°,
C :
une région où l'on a superposé deux grilles 65 et 66 afin de mieux cacher les sources de lumière.
In the view of variant grids of FIG. 3, there is shown:
AT :
a strip region cut out to create rectangular shapes 64 transverse to the strip, while retaining the edges 62,
B:
a region of this same strip where the rectangular fins 64 are folded at 90 °,
VS :
a region where two grids 65 and 66 have been superimposed in order to better hide the light sources.

Pour assurer le positionnement des grilles 65 et 66, on a prévu de créer, le long des bords 62, des protubérances équidistantes 67, destinées à s'engager dans des trous correspondants 68 de l'autre bande.To ensure the positioning of the grids 65 and 66, provision has been made to create, along the edges 62, equidistant protrusions 67, intended to engage in corresponding holes 68 of the other strip.

Les grilles utilisées dans la rampe d'éclairage selon l'invention sont de préférence de deux types selon que la rampe est disposée horizontalement ou verticalement pour éclairer une paroi, comme cela ressort des figures 2 et 3. Pour une rampe horizontale, on utilisera des grilles à ailettes 63 longitudinales alors que pour une rampe verticale on disposera des grilles à ailettes 64 transversales.The grids used in the light bar according to the invention are preferably of two types depending on whether the light bar is arranged horizontally or vertically to illuminate a wall, as can be seen in FIGS. 2 and 3. For a horizontal light bar, use will be made of grids with longitudinal fins 63 while for a vertical ramp we will have grids with transverse fins 64.

Ces deux variantes sont toutes deux représentées dans la coupe longitudinale de la figure 4 où l'on a à gauche une grille à ailettes longitudinales 63 et sur la droite une double grille à ailettes transversales 64.These two variants are both represented in the longitudinal section of FIG. 4 where there is on the left a grid with longitudinal fins 63 and on the right a double grid with transverse fins 64.

On retrouve dans cette figure 4 tous les composants décrits jusqu'ici. Le montage des composants de la rampe d'éclairage mural selon l'invention est le suivant : les bandes conductrices 31 et 32 sont superposées et leurs plaquettes 33 et 34 enfilées dans les passages 43 prévus dans le réflecteur 40. L'ensemble ainsi obtenu est glissé dans le profilé 20. Plus précisément les bandes conductrices sont introduites dans le rail central 26 tandis que le réflecteur 40 est glissé dans une des paires de rainures longitudinales 25 du profilé 20. On enfile alors autour de chaque plaquette 33, 34 un plot isolant 44 dans l'un des passages 43 avant de fixer les ampoules 50. On notera que les plots isolants 44 sont taillés en biseau et que leur partie la plus longue est située en-delà des lampes 50 pour protéger celles-ci. Les lampes 50 représentée à la figure 4 sont des lampes au Xenon possédant des contacts formant des boucles maintenues dans des fourches prévues à l'extrémité des plaquettes de contact. De manière connue, ces fourches peuvent être réalisées dans des pièces de contact intermédiaires, non représentées au dessin.We find in this figure 4 all the components described so far. The mounting of the components of the wall light bar according to the invention is as follows: the conductive strips 31 and 32 are superimposed and their plates 33 and 34 threaded in the passages 43 provided in the reflector 40. The assembly thus obtained is slid into the profile 20. More precisely, the conductive strips are introduced into the central rail 26 while the reflector 40 is slipped into one of the pairs of longitudinal grooves 25 of the profile 20. An insulating pad is then threaded around each plate 33, 34 44 in one of the passages 43 before fixing the bulbs 50. It will be noted that the insulating pads 44 are cut at a bevel and that their longest part is located beyond the lamps 50 to protect them. The lamps 50 represented in FIG. 4 are Xenon lamps having contacts forming loops held in forks provided at the end of the contact pads. In known manner, these forks can be produced in intermediate contact parts, not shown in the drawing.

L'alimentation électrique a lieu aux deux extrémités de la rampe, car la longueur des bandes conductrices est telle que subsiste - de chaque côté des paires de plaquettes recevant les ampoules - une plaquette 33, respectivement 34, permettant l'alimentation de la bande conductrice par l'ensemble conducteur 80. Le connecteur femelle 82 est enfiché sur l'une des plaquettes 33, 34 tandis que le connecteur mâle 83 est relié à une fiche d'alimentation, en arrière de la paroi intermédiaire 28 entre le profilé 20 et le rail 10, comme visible à la figure 2.The electrical supply takes place at the two ends of the ramp, because the length of the conductive strips is such that there remains - on each side of the pairs of plates receiving the bulbs - a plate 33, respectively 34, allowing the supply of the conductive strip by the conductor assembly 80. The female connector 82 is plugged into one of the plates 33, 34 while the male connector 83 is connected to a power plug, behind the intermediate wall 28 between the profile 20 and the rail 10, as shown in Figure 2.

Selon l'utilisation prévue, une glissera dans une paire de rainures 25 une ou deux grilles, à ailettes longitudinales 63 ou transversales 64, comme représenté à gauche et à droite de la figure 4, puis on fermera l'ensemble par un verre 70. Les longueurs des grilles et du verre sont inférieure à la longueur de la rampe. En effet chaque embout de fermeture 90 comporte une partie en saillie 95 destinée à s'appuyer sur l'extrémité de la grille 60, ainsi qu'une plaque de retour effilée 96 apte à maintenir le verre 70. Pour fermer totalement l'ensemble ainsi obtenu, la plaque de retour 96 s'engage entre les ailes 23 et 24 du profilé du boîtier.Depending on the intended use, one or two grids 25 will slide in a pair of grooves 25, with longitudinal fins 63 or transverse fins 64, as shown on the left and right of FIG. 4, then the assembly will be closed with a glass 70. The lengths of the grids and glass are less than the length of the ramp. In fact, each closure end piece 90 has a projecting part 95 intended to rest on the end of the grid 60, as well as a tapered return plate 96 capable of holding the glass 70. To completely close the assembly as well obtained, the return plate 96 engages between the wings 23 and 24 of the profile of the housing.

Dans une forme d'exécution non représentée au dessin, on peut prévoir également un profilé ayant les ouvertures 21 et 22 sur ses faces opposées, C'est ainsi que l'on pourrait par exemple éclairer un local ayant un plafond suspendu en noyant les rampes d'éclairage entre les panneaux formant ce plafond. On pourrait en outre prévoir un rail de fixation de la rampe qui comporte en outre les moyens de support des panneaux suspendus entre lesquels on pourrait encliqueter des rampes lumineuses selon l'invention.In an embodiment not shown in the drawing, one can also provide a profile having the openings 21 and 22 on its opposite faces, This is how one could for example light a room having a suspended ceiling by flooding the light bars between the panels forming this ceiling. One could also provide a rail for fixing the ramp which further comprises the means for supporting the suspended panels between which one could snap on the light ramps according to the invention.

En variante, la rampe selon l'invention peut également être utilisée pour l'éclairage de panneaux verticaux suspendus, par exemple des tapis, rideaux ou tapisseries. Dans ce cas on modifiera avantageusement le profilé pour qu'il permette également la fixation de ces panneaux.As a variant, the ramp according to the invention can also be used for lighting vertical hanging panels, for example carpets, curtains or tapestries. In this case, the profile will advantageously be modified so that it also allows these panels to be fixed.
