Description

Système d'éclairage Lighting system
La présente invention concerne un système d'éclairage comprenant un corps de matière transparente ou translucide et un élément de fond monté sur le corps de manière à définir ensemble un volume creux. Le système comprend en outre une source lumineuse montée sur l'élément de fond pour diffuser de la lumière à travers le corps. Il s'agit là d'un système d'éclairage classique qui peut être utilisé pour éclairer des lieux extérieurs, tels que des allées, des places, des chemins, etc. Le système d'éclairage peut également être utilisé pour éclairer des pièces d'habitation ou des locaux à usage divers. Toutefois, l'invention s'applique de manière privilégiée aux pavés lumineux destinés à être posés au sol ou à former un mur sous la forme d'un pavage constitué par la juxtaposition de plusieurs pavés lumineux.The present invention relates to a lighting system comprising a body of transparent or translucent material and a bottom element mounted on the body so as to define together a hollow volume. The system further includes a light source mounted on the bottom member for diffusing light through the body. This is a classic lighting system that can be used to illuminate outdoor places, such as aisles, squares, paths, etc. The lighting system can also be used to light living rooms or rooms with various uses. However, the invention applies in a preferred manner to the light pavers intended to be placed on the ground or to form a wall in the form of a paving formed by the juxtaposition of several light pavers.
On connaît déjà les documents DE 99 13 554 et DE 201 06 048 qui décrivent tous deux des systèmes d'éclairage comprenant un boîtier définissant un volume intérieur inscrit dans lequel est logé des sources d'éclairage, tels que des ampoules ou des diodes. Le boîtier est associé à un fond qui vient fermer le volume intérieur formé par le boîtier. Le volume intérieur peut également comprendre des systèmes de réflexion pour réfléchir une partie de la lumière émise par l'ampoule ou la diode dans des directions données. Ensuite, la lumière est diffusée à travers le boîtier qui comprend au moins une paroi transparente ou translucide.We already know the documents DE 99 13 554 and DE 201 06 048 which both describe lighting systems comprising a housing defining an interior volume inscribed in which is housed lighting sources, such as bulbs or diodes. The housing is associated with a bottom which closes the interior volume formed by the housing. The interior volume can also include reflection systems for reflecting part of the light emitted by the bulb or the diode in given directions. Then, the light is diffused through the housing which includes at least one transparent or translucent wall.
Dans ces deux systèmes d'éclairage de l'art antérieur, on se sert du volume intérieur formé par le boîtier pour y loger les composants du système d'éclairage, c'est-à-dire les moyens d'éclairage et le système de réflecteur. Bien entendu, lorsque l'ampoule ou la diode vient à casser, pour les remplacer, il faut retirer le fond du boîtier pour accéder au volume intérieur où est disposé l'ampoule ou la diode. Le volume intérieur du boîtier est donc accessible par retrait du fond. Bien entendu, après un certain temps, particulièrement lorsque le système d'éclairage est installé à l'extérieur, l'étanchéité entre le fond et le boîtier se détériore de sorte que le volume intérieur est alors exposé à l'humidité, aux saletés ainsi qu'aux organismes vivants tels que les insectes.In these two prior art lighting systems, the interior volume formed by the housing is used to house the components of the lighting system, that is to say the lighting means and the lighting system. reflector. Of course, when the bulb or the diode breaks, to replace them, it is necessary to remove the bottom of the housing to access the interior volume where the bulb or the diode is arranged. The interior volume of the housing is therefore accessible by removing the bottom. Of course, after a certain time, particularly when the lighting system is installed outside, the seal between the bottom and the housing deteriorates so that the interior volume is exposed to moisture, dirt and living organisms such as insects.
La présente invention a pour but de remédier aux inconvénients précités de l'art antérieur en définissant un système d'éclairage simple à fabriquer et à installer, qui nécessite une manipulation minimale pour remplacer les sources d'éclairage (ampoule ou diode), tout en garantissant une parfaite propreté et de ce fait une grande longévité du système d'éclairage. Ces problèmes sont d'autant plus vitaux que le système lumineux est un pavé lumineux installé à l'extérieur dans le sol. Pour atteindre ces buts, la présente invention propose un système d'éclairage comprenant un corps de matière transparente ou translucide, un élément de fond monté sur le corps de manière à former un réceptacle définissant un volume creux, une source lumineuse montée sur l'élément de fond pour diffuser de la lumière à travers le corps, caractérisé en ce que la source lumineuse est disposée à l'extérieur du volume creux. Ainsi, le système ne se sert pas du volume intérieur creux formé entre le corps et l'élément de fond pour y loger les composants remplaçables du système, à savoir la source lumineuse et plus particulièrement l'ampoule ou la diode.The present invention aims to remedy the aforementioned drawbacks of the prior art by defining a lighting system which is simple to manufacture and install, which requires minimal manipulation to replace the lighting sources (bulb or diode), while ensuring perfect cleanliness and therefore a long service life of the lighting system. These problems are all the more vital since the light system is a light block installed outside in the ground. To achieve these goals, the present invention provides a lighting system comprising a body of transparent or translucent material, a bottom element mounted on the body so as to form a receptacle defining a hollow volume, a light source mounted on the element. bottom to diffuse light through the body, characterized in that the light source is arranged outside the hollow volume. Thus, the system does not use the hollow interior volume formed between the body and the bottom element to house the replaceable components of the system, namely the light source and more particularly the bulb or the diode.
Selon une forme de réalisation de l'invention, le volume creux est isolé de manière étanche par rapport à l'extérieur, avantageusement au moyens d'un joint disposé entre le corps et l'élément de fond. L'élément de fond est ainsi rapporté et fixé de manière définitive sur le corps de sorte que le volume intérieur creux n'est pas accessible pour un élément quelconque, tel que l'eau, l'humidité, la saleté et/ ou les insectes. Le volume intérieur creux ne sert alors que d'espace de diffusion et/ou de réflexion, ou plus généralement de propagation de la lumière émise par la source lumineuse placée à l'extérieur de ce volume creux.According to one embodiment of the invention, the hollow volume is insulated in a sealed manner with respect to the outside, advantageously by means of a seal disposed between the body and the bottom element. The bottom element is thus attached and definitively fixed on the body so that the hollow interior volume is not accessible for any element, such as water, humidity, dirt and / or insects . The hollow interior volume then only serves as a space for diffusion and / or reflection, or more generally for propagation of the light emitted by the light source placed outside this hollow volume.
Avantageusement, l'élément de fond est partiellement transparent ou translucide. Ainsi, la lumière émise par la source lumineuse peut pénétrer à l'intérieur du volume creux par la partie transparente ou translucide de l'élément de fond. La lumière peut ainsi se propager dans le volume creux et sortir de manière avantageusement diffusée par le corps de matière transparente ou translucide. Avantageusement, l'élément de fond comprend un logement de réception pour la source lumineuse, ledit logement étant isolé du volume creux et communiquant avec l'extérieur à travers une ouverture d'insertion. Cette ouverture d'insertion sert d'ouverture de passage et de fixation pour l'ensemble d'éclairage qui est équipé de l'ampoule ou la diode à l'intérieur du logement de réception.Advantageously, the bottom element is partially transparent or translucent. Thus, the light emitted by the light source can penetrate inside the hollow volume through the transparent or translucent part of the bottom element. The light can thus propagate in the hollow volume and exit advantageously diffused by the body of transparent material or translucent. Advantageously, the bottom element comprises a receiving housing for the light source, said housing being isolated from the hollow volume and communicating with the outside through an insertion opening. This insertion opening serves as a passage and fixing opening for the lighting assembly which is equipped with the bulb or the diode inside the receiving housing.
Selon un autre aspect de l'invention, le corps définit un volume intérieur inscrit, le logement étant au moins partiellement disposé à l'intérieur du volume intérieur inscrit et entièrement à l'extérieur du volume creux. Avantageusement, le logement comprend une paroi transparente ou translucide.According to another aspect of the invention, the body defines an inscribed interior volume, the housing being at least partially disposed inside the inscribed interior volume and entirely outside the hollow volume. Advantageously, the housing comprises a transparent or translucent wall.
Selon un autre aspect de l'invention, le logement comprend une surface réflectrice de lumière pour diriger de la lumière issue de la source dans le volume creux. D'autre part, l'élément de fond peut comprendre au moins une surface réflectrice tournée vers l'intérieur du volume creux. Ainsi, la lumière émise par la source lumineuse placée à l'intérieur du logement est partiellement réfléchie par la surface réflectrice du logement vers la surface réflectrice formée autour du logement. Une partie de la lumière est directement diffusée sur la surface réflectrice située autour du logement.According to another aspect of the invention, the housing includes a light reflecting surface for directing light from the source into the hollow volume. On the other hand, the bottom element may include at least one reflecting surface facing the interior of the hollow volume. Thus, the light emitted by the light source placed inside the housing is partially reflected by the reflecting surface of the housing towards the reflecting surface formed around the housing. Part of the light is directly scattered on the reflective surface located around the housing.
Selon une forme de réalisation pratique, le logement de réception est formé par une douille comprenant une paroi latérale, une ouverture vers l'extérieur et une paroi d'obturation supérieure, la paroi latérale étant au moins partiellement transparent ou translucide, la paroi d'obturation définissant une surface réflectrice tournée vers l'intérieur du logement de sorte qu'une source lumineuse placée dans le logement émet de la lumière directement à travers la paroi latérale dans le volume creux et sur la surface réflectrice qui la réfléchit dans le volume creux à travers la paroi latérale. Avantageusement, l'ouverture du logement est de forme générale cylindrique, et reçoit un élément d'étanchéité, la source lumineuse étant montée sur un support emmanché en force dans l'élément d'étanchéité pour isoler ainsi le logement de manière étanche par rapport à l'extérieur. De préférence, le logement est formé de manière sensiblement centrale par rapport à l'élément de fond, et s'étend dans le volume inscrit du corps en pointant avec sa paroi d'obturation vers le corps.According to a practical embodiment, the receiving housing is formed by a socket comprising a side wall, an opening towards the outside and an upper closure wall, the side wall being at least partially transparent or translucent, the wall of shutter defining a reflective surface facing the interior of the housing so that a light source placed in the housing emits light directly through the side wall in the hollow volume and on the reflective surface which reflects it in the hollow volume to through the side wall. Advantageously, the opening of the housing is of generally cylindrical shape, and receives a sealing element, the light source being mounted on a support force-fitted into the sealing element to thus isolate the housing in a sealed manner with respect to outside. Preferably, the housing is formed so substantially central with respect to the bottom element, and extends into the inscribed volume of the body while pointing with its closure wall towards the body.
Selon un autre aspect pratique de l'invention, l'élément de fond comprend une structure périphérique de bord extérieur, une zone centrale et une zone intermédiaire entourant la zone centrale et entourée par la structure de bord, le logement étant situé dans la zone centrale, la surface réflectrice étant située dans la zone intermédiaire, et la structure de bord comprenant au moins une collerette d'appui destinée à coopérer avec un décrochement d'appui formé par le corps, un joint d'étanchéité étant avantageusement disposé entre la collerette et le décrochement. Avantageusement, la structure de bord comprend une jupe destinée à s'engager dans le corps, la jupe formant une extrémité libre adaptée à venir avantageusement en butée sur un épaulement interne formé par le corps.According to another practical aspect of the invention, the bottom element comprises an outer edge peripheral structure, a central area and an intermediate area surrounding the central area and surrounded by the edge structure, the housing being located in the central area , the reflecting surface being located in the intermediate zone, and the edge structure comprising at least one support flange intended to cooperate with a support recess formed by the body, a seal being advantageously disposed between the flange and the dropout. Advantageously, the edge structure comprises a skirt intended to engage in the body, the skirt forming a free end adapted to advantageously come into abutment on an internal shoulder formed by the body.
Le système d'éclairage selon l'invention peut avantageusement être utilisé pour réaliser un pavage de sol ou de mur constitué par une juxtaposition de plusieurs systèmes d'éclairage pour réaliser un motif esthétique ou fonctionnel.The lighting system according to the invention can advantageously be used to produce a floor or wall paving formed by a juxtaposition of several lighting systems to achieve an aesthetic or functional pattern.
Dans ce cas, le corps de matière transparente ou translucide peut présenter la forme d'un pavé généralement rectangulaire ou éventuellement hexagonal. De cette manière, plusieurs corps peuvent être placés les uns à côté des autres de manière régulière et jointive. L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.In this case, the body of transparent or translucent material may have the shape of a generally rectangular or possibly hexagonal block. In this way, several bodies can be placed next to each other in a regular and contiguous manner. The invention will now be described more fully with reference to the accompanying drawings which give an embodiment of the invention by way of non-limiting example.
Sur les figures :In the figures:
- la figure 1 est une représentation schématique d'un morceau de sol ou de mur revêtu à l'aide de plusieurs systèmes d'éclairage selon l'invention pour réaliser un motif en forme de H,FIG. 1 is a schematic representation of a piece of floor or wall coated with the aid of several lighting systems according to the invention to produce an H-shaped pattern,
- la figure 2 est une vue en coupe transversale verticale fortement agrandie d'une source lumineuse selon l'invention,FIG. 2 is a greatly enlarged vertical cross-section view of a light source according to the invention,
- la figure 3 est une vue en coupe transversale éclatée d'un système d'éclairage selon une forme de réalisation de l'invention, etFIG. 3 is an exploded cross-sectional view of a lighting system according to an embodiment of the invention, and
- la figure 4 est une vue à l'état monté du système de la figure 3. Le système d'éclairage représenté sur les figures 3 et 4 peut être utilisé en tant que système d'éclairage individuel dont la source lumineuse est connectée à une source de courant par un câble d'alimentation connecté directement au secteur ou par l'intermédiaire d'un transformateur adaptateur. Le système d'éclairage selon l'invention peut encore être utilisé pour réaliser un pavage de sol ou de mur, comme représenté sur la figure 1. Dans ce cas, plusieurs systèmes d'éclairage sont disposés selon un agencement souhaité pour obtenir un effet esthétique et/ ou fonctionnel. Sur la figure 1, on peut voir plusieurs systèmes d'éclairage 1 disposés dans un dallage formé de dalles carrées l'. Les systèmes d'éclairage 1 sont disposés de manière à réaliser une forme de H. Pour ce faire, les systèmes d'éclairage 1 sont disposés de manière jointive soit l'un au dessus de l'autre pour former les deux barres verticales du H, soit côte à côte pour former la barre horizontale du H. Les systèmes d'éclairage présentent ici une forme générale rectangulaire mais on peut bien évidemment prévoir d'autres formes géométriques telles que carrées, triangulaires, en losange ou hexagonales. A vrai dire, toutes formes permettant une disposition répétée et jointive du système d'éclairage est appropriées pour réaliser un pavage de sol ou mural. A la place du motif en H, on aurait très bien pu mettre un motif plus complexe dans lequel les systèmes d'éclairage ne sont pas tous jointives. Selon l'invention les systèmes d'éclairage 1 sont reliés en parallèle par un câble d'alimentation 7 connecté à un transformateur adaptateur 8 lui-même raccordé au secteur. Un motif réalisé avec des systèmes d'éclairage 1 selon l'invention peut comprendre un ou plusieurs câble(s) d'alimentation 7. Ces câbles peuvent être reliés à un seul et même transformateur adaptateur ou à plusieurs transformateurs adaptateurs 8.- Figure 4 is a view in the assembled state of the system of Figure 3. The lighting system shown in FIGS. 3 and 4 can be used as an individual lighting system, the light source of which is connected to a current source by a power cable connected directly to the mains or by means of 'an adapter transformer. The lighting system according to the invention can also be used to make a floor or wall paving, as shown in Figure 1. In this case, several lighting systems are arranged in a desired arrangement to obtain an aesthetic effect and / or functional. In Figure 1, we can see several lighting systems 1 arranged in a pavement formed of square tiles. The lighting systems 1 are arranged so as to form an H shape. To do this, the lighting systems 1 are arranged contiguously, one above the other to form the two vertical bars of the H , or side by side to form the horizontal bar of the H. The lighting systems here have a generally rectangular shape but it is obviously possible to provide other geometric shapes such as square, triangular, diamond or hexagonal. In fact, all forms allowing a repeated and contiguous arrangement of the lighting system are suitable for making floor or wall paving. Instead of the H pattern, we could very well have put a more complex pattern in which the lighting systems are not all contiguous. According to the invention, the lighting systems 1 are connected in parallel by a power cable 7 connected to an adapter transformer 8 which is itself connected to the mains. A pattern produced with lighting systems 1 according to the invention can comprise one or more power supply cable (s) 7. These cables can be connected to a single adapter transformer or to several adapter transformers 8.
On se référera maintenant plus particulièrement aux figures 3 et 4 pour expliquer un système d'éclairage selon une forme de réalisation non limitative de l'invention. Ce système d'éclairage comprend plusieurs éléments constitutifs, à savoir un corps 2, un élément de fond 3 et un ensemble d'éclairage 5. Bien entendu, l'ensemble d'éclairage 5 est relié à un câble d'alimentation électrique 7. Le corps 2 peut être entièrement ou partiellement réalisé en une matière transparente ou translucide. De préférence, le corps 2 est réalisé de manière monobloc en verre dont certaines parties peuvent être opaques, et d'autres parties transparentes ou translucides. En se référant à la figure 3, le corps 2 comprend une paroi supérieure 21 sur la périphérie de laquelle s'étend un pourtour périphérique 22. Le pourtour 22 s'étend tout autour de la paroi supérieure 21. Le corps 2 présente ainsi une forme de boîtier, de godet ou de récipient définissant un volume intérieur inscrit Vi. La paroi supérieure 21 comprend une surface externe 211 qui peut être parfaitement plane ou éventuellement profilée et une surface intérieure 212 donnant dans le volume intérieur inscrit. Le pourtour périphérique 22, qui est ici de forme rectangulaire, comprend une paroi externe 221, une paroi interne 222 ainsi qu'une extrémité libre 23 qui forme le bord périphérique annulaire rectangulaire du corps. La paroi externe 221 peut être parfaitement plane par secteur ou encore profilée. La paroi interne 222 forme un épaulement périphérique 223 dirigé vers FexttémitéReference will now be made more particularly to FIGS. 3 and 4 to explain a lighting system according to a nonlimiting embodiment of the invention. This lighting system comprises several constituent elements, namely a body 2, a bottom element 3 and a lighting assembly 5. Of course, the lighting assembly 5 is connected to an electrical supply cable 7. The body 2 can be entirely or partially made of a transparent or translucent material. Preferably, the body 2 is made in a single piece of glass, some parts of which may be opaque, and other parts which are transparent or translucent. Referring to Figure 3, the body 2 includes an upper wall 21 on the periphery of which extends a peripheral periphery 22. The periphery 22 extends all around the upper wall 21. The body 2 thus has a shape of housing, cup or container defining an interior volume inscribed Vi. The upper wall 21 includes an external surface 211 which can be perfectly flat or possibly profiled and an internal surface 212 giving into the inscribed interior volume. The peripheral periphery 22, which is here of rectangular shape, comprises an external wall 221, an internal wall 222 as well as a free end 23 which forms the rectangular annular peripheral edge of the body. The external wall 221 can be perfectly flat by sector or even profiled. The internal wall 222 forms a peripheral shoulder 223 directed towards the end
23. D'autre part, l'extrémité 23 est formée avec un décrochement 231 dirigé vers l'intérieur du corps.23. On the other hand, the end 23 is formed with a recess 231 directed towards the interior of the body.
La paroi supérieure 21 est au moins partiellement et/ ou localement transparente ou translucide. Pour améliorer sa capacité de diffusion de lumière, la surface interne 212 peut éventuellement être rodée. Quant au pourtour périphérique 22, il peut indifféremment être transparent ou opaque. Le volume intérieur inscrit Vi formé par le corps 2 est défini par les surfaces internes 212 et 222. Le volume intérieur inscrit Vi peut être défini comme étant le volume de produit fluide que pourrait contenir le corps 2 lorsque rempli jusqu'au niveau de son bord 23.The upper wall 21 is at least partially and / or locally transparent or translucent. To improve its light scattering capacity, the internal surface 212 can optionally be lapped. As for the peripheral periphery 22, it can either be transparent or opaque. The internal volume registered Vi formed by the body 2 is defined by the internal surfaces 212 and 222. The internal volume registered Vi can be defined as the volume of fluid which the body 2 could contain when filled to the level of its edge 23.
L'élément de fond 3 est de préférence réalisé de manière monobloc par injection moulage de matière plastique. Toutefois, l'élément de fond 3 peut également être réalisé par une technique de comoulage ou de surmoulage. Une partie de l'élément de fond pourrait être réalisée en métal et une autre partie en matière plastique ou en verre. Différentes combinaisons sont envisageables.The bottom element 3 is preferably made in a single piece by injection molding of plastic material. However, the bottom element 3 can also be produced by a co-molding or overmolding technique. Part of the bottom element could be made of metal and another part of plastic or glass. Different combinations are possible.
L'élément de fond ne comprend pas de préférence de trou transversant. L'élément de fond 3 comprend une structure de bord 33 qui définit la périphérie extérieure de l'élément de fond. La structure de bord 33 comprend une jupe périphérique 312 de forme générale rectangulaire destinée à venir se loger à l'intérieur de la paroi latérale périphérique 22 du corps 2. La structure de bord 33 comprend également une collerette radiale périphérique 313 qui fait saillie vers l'extérieur. Cette collerette 313 est destinée à venir se loger dans le décrochement 231 formé par la paroi d'extrémité 23 du corps 2. Avantageusement, l'extrémité supérieure libre de la jupe 312 vient en contact de l'épaulement 223 lorsque la collerette 313 est logée dans le décrochement 231. De préférence, la jupe 312 vient en butée sur l'épaulement 223 alors que la collerette 313 est encore légèrement en écartement du décrochement 231. De cette manière, un joint d'étanchéité 233 peut être réalisé entre l'élément de fond 3 et le corps 2 au niveau de la structure de bord 33, et plus précisément au niveau de la collerette 313. Le joint de col 233, visible sur la figure 4, est formé dans le décrochement 231 au dessus et autour de la collerette 313.The bottom element preferably does not include a transverse hole. The bottom element 3 comprises an edge structure 33 which defines the outer periphery of the bottom element. The edge structure 33 comprises a peripheral skirt 312 of generally rectangular shape intended to be housed inside the peripheral lateral wall 22 of the body 2. The edge structure 33 also comprises a peripheral radial flange 313 which projects towards the 'outside. This flange 313 is intended to be housed in the recess 231 formed by the end wall 23 of the body 2. Advantageously, the free upper end of the skirt 312 comes into contact with the shoulder 223 when the flange 313 is housed in the recess 231. Preferably, the skirt 312 abuts on the shoulder 223 while the flange 313 is still slightly apart from the recess 231. In this way, a seal 233 can be produced between the element bottom 3 and the body 2 at the edge structure 33, and more precisely at the flange 313. The neck seal 233, visible in FIG. 4, is formed in the recess 231 above and around the collar 313.
La structure de bord 33 comprend optionnellement mais avantageusement un rebord 311 qui fait saillie vers le bas à partir de la jonction reliant la collerette 313 à la jupe 212. Le rebord 311 et la jupe 312 peuvent s'étendre de manière alignée comme on peut le voir sur la figure 3. L'élément de fond 3 forme à l'intérieur de la structure de bord 33 un système de réflexion 32 et une douille centrale 31. Deux douilles sont cependant envisageables.The edge structure 33 optionally but advantageously comprises a flange 311 which projects downwards from the junction connecting the flange 313 to the skirt 212. The flange 311 and the skirt 312 can extend in an aligned manner as can be see in Figure 3. The bottom element 3 forms inside the edge structure 33 a reflection system 32 and a central socket 31. Two sockets are however possible.
La douille centrale 31 est disposée sensiblement au centre de l'élément de fond 3 de sorte qu'elle sera également disposée de manière centrale par rapport au corps 2 une fois l'élément de fond 3 rapporté sur le corps 2. La douille 31 comprend une paroi latérale 312, une paroi d'obturation supérieure 313 et une ouverture d'insertion 314. Lorsque l'on regarde la figure 3, avec le corps 2 situé au dessus de l'élément de fond 3, la paroi d'obturation 213 pointe vers le corps 2 alors que l'ouverture d'insertion 314 est tournée vers le bas. La paroi latérale 312, qui est ici de forme générale cylindrique ou tronconique, s'étend sensiblement verticalement. La paroi latérale 312 est au moins partiellement et localement transparente ou translucide de manière à laisser passer un faisceau lumineux. La paroi d'obturation 313 est réalisée en forme de cône dont la pointe est orientée à l'intérieur de la douille. La paroi d'obturation 313 forme une surface réflectrice apte à réfléchir un faisceau lumineux issu de l'intérieur de la douille 31.The central bush 31 is disposed substantially in the center of the bottom element 3 so that it will also be centrally disposed relative to the body 2 once the bottom element 3 is attached to the body 2. The bush 31 includes a side wall 312, an upper closure wall 313 and an insertion opening 314. When looking at FIG. 3, with the body 2 located above the bottom element 3, the closure wall 213 points towards the body 2 while the insertion opening 314 is facing downwards. The side wall 312, which here is generally cylindrical or frustoconical, extends substantially vertically. The side wall 312 is at least partially and locally transparent or translucent so as to allow a light beam to pass. The closing wall 313 is made in the form of a cone, the point of which is oriented inside the socket. The closure wall 313 forms a reflective surface capable of reflecting a light beam coming from inside the socket 31.
La douille 31 occupe une zone centrale de l'élément de fond 3 et la structure de bord 33 occupe une zone externe de l'élément de fond 3. Entre cette zone centrale et cette zone périphérique s'étend une zone intermédiaire formant un système de surface réflectrice 32. Les surfaces réflectrices 32 sont orientées de telle manière qu'un faisceau lumineux issu de l'intérieur de la douille 31 va être réfléchi vers la paroi supérieure 21 du corps 2.The sleeve 31 occupies a central zone of the bottom element 3 and the edge structure 33 occupies an external zone of the bottom element 3. Between this central zone and this peripheral zone extends an intermediate zone forming a system of reflective surface 32. The reflective surfaces 32 are oriented in such a way that a light beam coming from inside the socket 31 will be reflected towards the upper wall 21 of the body 2.
Une fois l'élément de fond 3 rapporté et fixé sur le corps 2, avec l'utilisation éventuelle d'un joint d'étanchéité 233, ils forment ensemble un réceptacle définissant un volume creux Vc visible sur la figure 4. Ce réceptacle est parfaitement isolé de l'extérieur du fait que le corps 2 ainsi que l'élément de fond 3 ne présentent aucun orifice ou passage vers l'extérieur. Le volume creux Vc du réceptacle est délimité par les surfaces intérieures 212 et 222, la paroi interne de la jupe 312, les surfaces réflectrices 32, la surface externe de la paroi latérale 312 ainsi que la surface externe de la paroi d'obturation 313. L'ouverture d'insertion 314 de la douille 31 ne permet pas de communiquer avec l'intérieur du volume creux Vc, tout en étant disposé au moins partiellement à l'intérieur du volume inscrit Vi. Plus précisément, la majeure partie de la douille 31 est disposée à l'intérieur du volume inscrit Vi, alors que son ouverture 314 est située à l'extérieur de ce volume inscrit Vi. H en est de même pour une partie des surfaces réflectrices 32.Once the bottom element 3 is attached and fixed to the body 2, with the possible use of a seal 233, they together form a receptacle defining a hollow volume Vc visible in FIG. 4. This receptacle is perfectly isolated from the outside because the body 2 and the bottom element 3 have no orifice or passage to the outside. The hollow volume Vc of the receptacle is delimited by the internal surfaces 212 and 222, the internal wall of the skirt 312, the reflecting surfaces 32, the external surface of the side wall 312 as well as the external surface of the closure wall 313. The insertion opening 314 of the sleeve 31 does not allow communication with the interior of the hollow volume Vc, while being disposed at least partially inside the inscribed volume Vi. More specifically, the major part of the sleeve 31 is disposed inside the volume inscribed Vi, while its opening 314 is located outside of this volume inscribed Vi. It is the same for part of the reflecting surfaces 32.
Le réceptacle ne contient aucun composant du système d'éclairage : il n'est rempli que d'un gaz, en général de l'air, qui est parfaitement inerte étant donné qu'il est isolé de l'extérieur par le joint 233. Cependant, de la lumière peut pénétrer à l'intérieur du réceptacle à travers la paroi latérale 312 de la douille 31. Cette lumière peut être réfléchie par la paroi d'obturation 313 ainsi que par le système de surfaces réflectrices 32. Ensuite, la lumière ainsi diffusée et réfléchie peut passer à travers la paroi supérieure 21 du corps 2. Le volume creux Vc du réceptacle sert donc uniquement d'espace de propagation de lumière issue de la douille 31. Bien entendu, la forme de la douille 31 ne doit pas être considérée comme limitative : d'autres formes de douille sont également possible. La douille 31 forme ainsi un logement interne 311 déUmité par la paroi latérale 312 et la paroi d'obturation 313 et ouvert vers l'extérieur à travers l'ouverture d'insertion 314.The receptacle does not contain any component of the lighting system: it is only filled with a gas, generally air, which is perfectly inert since it is isolated from the outside by the gasket 233. However, light can penetrate inside the receptacle through the side wall 312 of the socket 31. This light can be reflected by the closure wall 313 as well as by the system of reflective surfaces 32. Next, the light thus disseminated and reflected can pass through the upper wall 21 of the body 2. The hollow volume Vc of the receptacle therefore only serves as a space for propagation of light coming from the socket 31. Of course, the shape of the socket 31 should not be considered as limiting : other forms of socket are also possible. The socket 31 thus forms an internal housing 311 demounted by the side wall 312 and the closure wall 313 and open towards the outside through the insertion opening 314.
L'ensemble d'éclairage 5 comprend une source lumineuse 53 et un support de source 51 et un capuchon 52. La source 53 est montée sur le support 51 et le capuchon 52 est rapporté et fixé sur le support 51.The lighting assembly 5 comprises a light source 53 and a source support 51 and a cap 52. The source 53 is mounted on the support 51 and the cap 52 is attached and fixed to the support 51.
La source lumineuse peut être une ampoule de nature quelconque, mais de préférence la source est une diode électroluminescente LED.The light source can be a bulb of any kind, but preferably the source is a light emitting diode LED.
Selon l'invention, le support 51 est inséré à l'intérieur du logement 31 de manière à ce que la source 53 soit centrée à l'intérieur du logement. De préférence, le support 51 est emmanché en force à l'intérieur de l'ouverture d'insertion 314. De préférence, cet emmanchage en force réalise une étanchéité au niveau de l'ouverture 314 de manière à isoler le logement 311 de l'extérieur. Selon une forme de réalisation pratique, une garniture d'étanchéité 4 est disposée au niveau de l'ouverture d'insertion 314, et le support 51 est emmanché dans cette garniture d'étanchéité 4 en la comprimant et en la pressant contre l'ouverture d'insertion 314. Ainsi, une étanchéité parfaite est réalisée par un simple emmanchage en force qui est effectué par un déplacement translatif axial du support 51. Aucun outil n'est nécessaire.According to the invention, the support 51 is inserted inside the housing 31 so that the source 53 is centered inside the housing. Preferably, the support 51 is force-fitted inside the insertion opening 314. Preferably, this force-fitting seals at the opening 314 so as to isolate the housing 311 from the outside. According to a practical embodiment, a seal 4 is arranged at the level of the insertion opening 314, and the support 51 is fitted into this seal 4 by compressing it and pressing it against the opening insertion 314. Thus, a perfect seal is achieved by a simple force fitting which is effected by an axial translational movement of the support 51. No tool is necessary.
Le support 51, en coopération avec le capuchon 52 forment des moyens de connexion électrique rapides sur un câble d'alimentation 7.The support 51, in cooperation with the cap 52, forms rapid electrical connection means on a power cable 7.
En se référant maintenant à la figure 2, on peut voir une source lumineuse 5 selon l'invention de manière très fortement agrandie. L'ensemble d'éclairage 5, au niveau de son support 51, forme un manchon d'insertion sensiblement cylindrique 511 destiné à coopérer avec la douille 31 pour la fixation et l'étanchéité de l'ensemble d'éclairage 5 dans le logement 31. Plus précisément, la paroi externe du manchon cylindrique 511 vient en prise serrante à l'intérieur de la garniture d'étanchéité 4 de manière à la déformer élastiquement vers l'extérieur en contact appuyé étanche dans l'ouverture d'insertion 314. Ce manchon d'insertion 511 abrite à l'intérieur une petite plaque de circuit imprimée 514 sur laquelle la source 53 est montée. Le support 51 comprend également une embase 512 destinée à coopérer avec le capuchon 52. Cette embase 512 est pourvue de deux pointes d'incision 516 formées aux extrémités de deux broches 515 reliant chacune la plaque de circuit imprimée 514. L'embase 512 forme également des moyens d'assemblage 513 destinés à coopérer avec des brides d'assemblage 523 formées par le capuchon 52. Le capuchon 52 forme une plaque de fond 521 au niveau de laquelle sont formés des moyens d'accrochage 522 destinés à recevoir de manière avantageusement coulissante le câble d'alimentation 7. Les moyens d'accrochage 522 peuvent par exemple former un logement de réception et d'accrochage dans lequel le câble d'alimentation 7 peut être inséré en force et maintenu en place. Les moyens d'accrochage 522 peuvent par exemple former deux crochets 525 destinés à venir en prise dans des rainures correspondantes formées par le câble 7. Avantageusement, les moyens d'accrochage forment également des moyens de détrompage 524 sous la forme d'un évidement à l'intérieur duquel une nervure 74 du câble 7 peut venir s'insérer. Ainsi, l'orientation du capuchon 52 sur le câble 7 est imposée.Referring now to FIG. 2, one can see a light source 5 according to the invention in a very greatly enlarged manner. The lighting assembly 5, at its support 51, forms a substantially cylindrical insertion sleeve 511 intended to cooperate with the socket 31 for fixing and sealing the lighting assembly 5 in the housing 31 More specifically, the external wall of the cylindrical sleeve 511 comes into tight engagement inside the seal 4 so as to deform it elastically outwards in sealed pressed contact in the insertion opening 314. This insertion sleeve 511 houses inside a small printed circuit board 514 on which the source 53 is mounted. The support 51 also includes a base 512 intended to cooperate with the cap 52. This base 512 is provided with two incision points 516 formed at the ends of two pins 515 each connecting the printed circuit board 514. The base 512 also forms assembly means 513 intended to cooperate with assembly flanges 523 formed by the cap 52. The cap 52 forms a bottom plate 521 at the level of which hooking means 522 are formed intended to receive advantageously sliding the power cable 7. The attachment means 522 can for example form a receiving and attachment housing in which the power cable 7 can be forcefully inserted and held in place. The attachment means 522 can for example form two hooks 525 intended to engage in corresponding grooves formed by the cable 7. Advantageously, the attachment means also form keying means 524 in the form of a recess at inside which a rib 74 of the cable 7 can be inserted. Thus, the orientation of the cap 52 on the cable 7 is imposed.
Le câble 7 peut par exemple se présenter sous la forme d'un cordon isolant 72 à l'intérieur duquel sont noyés deux fils conducteurs 71. Le cordon 72 est réalisé en un matériau susceptible d'être facilement incisé ou percé. Deux câbles individuels classiques peuvent également être utilisés. Lorsque le câble 7 est en place dans les moyens d'accrochage 522, on peut rapporter le capuchon 52 sur l'embase 512. Si le capuchon n'est pas placé de manière idéale par rapport à l'embase 512, il est toujours possible de déplacer le capuchon 52 en faisant coulisser le câble à l'intérieur de ses moyens d'accrochage 522. Une fois la position idéale atteinte, le capuchon 52 est rapporté sur l'embase 512 ce qui a pour effet de percer le cordon 72 à l'aide des pointes 516 qui vont parvenir jusqu'au fil conducteur 71. De cette manière, un contact électrique est établi aisément entre les fils 71 et la source 53 par rintermédiaire des broches 515 et de la plaque de circuit imprimée 514. A la place des pointes 516, on peut très bien utiliser un système de connexion utilisant des contacts autodénudants à fente. Avec cette technique de pointe perforante ou de contact autodénudant incisant, on peut établir un contact électrique sans outils et sans avoir à dénuder ou à couper le câble d'alimentation. Ainsi, le câble fait fonction de bus d'alimentation reliant en parallèle tous les systèmes d'éclairage sans interruption, à la manière d'une guirlande électrique.The cable 7 may for example be in the form of an insulating bead 72 inside which two conductive wires 71 are embedded. The bead 72 is made of a material capable of being easily incised or pierced. Two conventional individual cables can also be used. When the cable 7 is in place in the attachment means 522, the cap 52 can be attached to the base 512. If the cap is not ideally placed relative to the base 512, it is always possible move the cap 52 by sliding the cable inside its hooking means 522. Once the ideal position has been reached, the cap 52 is attached to the base 512 which has the effect of piercing the cord 72 at using the points 516 which will reach the conducting wire 71. In this way, a electrical contact is easily established between the wires 71 and the source 53 by means of the pins 515 and the printed circuit board 514. Instead of the pins 516, it is very possible to use a connection system using insulation displacement slotted contacts. With this cutting-edge perforating or incisal self-stripping contact technique, electrical contact can be established without tools and without having to strip or cut the power cable. Thus, the cable acts as a power bus connecting all the lighting systems in parallel without interruption, like an electric garland.
Avec le système d'éclairage selon l'invention, il n'est même pas nécessaire d'utiliser un outil quelconque pour réaliser son montage. Dans un premier temps, les supports 51 sont emmanchés en force dans les logements des réceptacles formés par un corps et un élément de fond. Dans un second temps, le capuchon 52 est mis en place sur la longueur du câble d'ahmentation 7, puis le capuchon est rapporté sur le support 51 de manière à réaliser la connexion électrique. Il suffit ensuite de disposer les systèmes d'éclairage à la manière de pavés autobloquants pour réaliser le motif souhaité. La conception particulière du réceptacle formée par le corps et l'élément de fond prolonge considérablement la durée de vie de cet élément. D'autre part, la conception de la source lumineuse emmanchable en force dans le réceptacle et connectable électriquement d'une manière très simple rend le montage particulièrement aisé et rapide. With the lighting system according to the invention, it is not even necessary to use any tool for mounting it. Firstly, the supports 51 are force-fitted into the receptacles of the receptacles formed by a body and a bottom element. In a second step, the cap 52 is put in place along the length of the supply cable 7, then the cap is attached to the support 51 so as to make the electrical connection. It is then enough to arrange the lighting systems in the manner of interlocking blocks to achieve the desired pattern. The particular design of the receptacle formed by the body and the bottom element considerably prolongs the life of this element. On the other hand, the design of the light source which can be force-fitted into the receptacle and electrically connectable in a very simple manner makes mounting particularly easy and rapid.
