Description

Domaine techniqueTechnical area

La présente invention est du domaine des appareils d'éclairage domestique et se rapporte plus particulièrement à un équipement d'étanchéité pour un luminaire du type de ceux prévus pour être monté en encastrement dans une paroi d'un bâtiment telle que non limitativement faux plafond, cloison verticale de séparation et autre. Un tel luminaire est connu dans le domaine d'activité sous le terme de spot.The present invention is in the field of domestic lighting appliances and relates more particularly to a sealing equipment for a luminaire of the type of those intended to be mounted in a recess in a wall of a building such as not limited to a false ceiling, vertical partition wall and other. Such a luminaire is known in the field of activity under the term spot.

État de la technique antérieure.State of the art

On connaît de l'état de la technique des luminaires prévus pour être encastrés dans des perçages pratiqués dans des parois de séparation d'un bâtiment tel qu'un habitat, un local commercial et autre. Ces parois peuvent être du type de celle connues sous le nom commercial de « PLACOPATRE » et peuvent constituer les faux plafonds du bâtiment. Typiquement, ces luminaires comprennent une lampe d'éclairage comprenant une ampoule, habituellement de forme tronconique, prolongée vers l'arrière par un culot de forme cylindrique prévu pour être raccordé électriquement au réseau de distribution électrique du bâtiment. Cette lampe est logée de manière amovible dans un support formé d'une douille d'emmanchement prévue pour être engagée dans le perçage traversant de la paroi de séparation et d'une collerette de propreté ménagée à l'une des deux extrémités de la douille. Cette collerette de propreté est prévue pour venir en appui contre la face apparente de la paroi de séparation ou face avant et masquer le perçage pratiqué dans cette dernière. Un ou plusieurs joncs élastiques solidaires de la douille d'emmanchement et aptes à venir en prise avec une gorge pratiquée dans l'ampoule au niveau de sa grande base, assurent la fixation amovible de l'ampoule dans le support et plus précisément dans le logement que détermine ladite douille. En vue de la fixation du luminaire à la paroi de séparation, l'ampoule est engagée et fixée dans la douille du support et des crochets élastiques portés par la douille support, sous l'effet de leur élasticité viennent en appui contre la face arrière de la paroi de séparation à la périphérie du perçage traversant formé dans cette dernière. Toujours sous l'effet de l'élasticité des crochets, le support est sollicité dans le perçage traversant et la collerette de la douille vient en appui contre la face apparente de la paroi de séparation.Luminaires are known from the state of the art intended to be embedded in bores made in partition walls of a building such as a dwelling, a commercial space and the like. These walls may be of the type known under the trade name of "PLACOPATRE" and may constitute the false ceilings of the building. Typically, these luminaires comprise a lighting lamp comprising a bulb, usually of frustoconical shape, extended rearwardly by a cylindrical shaped base adapted to be electrically connected to the electrical distribution network of the building. This lamp is removably housed in a support formed of a fitting sleeve adapted to be engaged in the through-hole of the partition wall and a flange provided at one of the two ends of the sleeve. This flange cleanliness is provided to bear against the apparent face of the partition or front face and mask the drilling in the latter. One or more resilient rods integral with the sleeve and adapted to engage with a groove in the bulb at its large base, provide removable attachment of the bulb in the support and more specifically in the housing that determines said socket. In order to fix the luminaire to the partition wall, the bulb is engaged and fixed in the socket of the support and elastic hooks carried by the support sleeve, under the effect of their elasticity come to bear against the rear face of the partition wall at the periphery of the through bore formed in the latter. Always under the effect of the elasticity of the hooks, the support is biased in the through bore and the collar of the sleeve bears against the apparent face of the partition wall.

La face arrière de la paroi de séparation est habituellement tournée vers un vide technique accueillant notamment le réseau de distribution électrique du bâtiment.The rear face of the partition wall is usually turned to a technical vacuum including welcoming the electrical distribution network of the building.

Exposé de l'inventionPresentation of the invention Problème technique.Technical problem.

On sait que les nouveaux bâtiments doivent notamment répondre aux normes légales en matière de basse consommation. Ainsi leur volume interne et plus particulièrement le volume d'habitation, doit présenter une isolation thermique adaptée ainsi qu'une étanchéité à l'air appropriée pour réduire les pertes énergétiques tant avec l'extérieur qu'avec les volumes non habitables du local, lesquels, peuvent être en communication par des éléments d'aération avec l'extérieur. On sait également que des différences significatives de températures peuvent apparaître entre les volumes habitables et les volumes non habitables et être à l'origine de flux convectifs direct au travers d'ouvertures de communication entre ces deux types de volumes.We know that new buildings must meet the legal standards for low consumption. Thus their internal volume and more particularly the volume of housing, must have a suitable thermal insulation and an airtightness appropriate to reduce energy losses with both the outside and the non-habitable volumes of the premises, which , may be in communication with ventilation elements with the outside. It is also known that significant differences in temperatures can appear between the habitable volumes and the non-habitable volumes and be at the origin of direct convective flows through communication openings between these two types of volumes.

Ces volumes non habitables ou non utilisables sont constitués par les volumes morts de l'habitation ou bien par les vides techniques, par exemple ceux situés sous la toiture on bien ceux situés entre un plafond principal et un faux plafond et accueillant habituellement les réseaux de distribution électriques et autres.These non-habitable or unusable volumes are constituted by the dead volumes of the house or by the technical voids, for example those located under the roof or those located between a main ceiling and a false ceiling and usually hosting the distribution networks electric and others.

L'inconvénient des luminaires connus, tels que précédemment décrits, réside dans le fait que leur implantation requiert la formation de perçages traversants dans les parois de séparation, et leur présence dans ces perçages n'assure en rien une quelconque étanchéité. Un autre inconvénient réside dans le fait qu'un éclairement optimal requiert un nombre élevé de luminaires multipliant ainsi le nombre d'ouvertures vers les volumes techniques et par voie de conséquence l'importance des pertes d'étanchéité à l'air. De plus ces luminaires sont à l'origine de la formation de ponts thermiques du fait de la différence de pouvoir isolant entre la paroi de séparation et le luminaire, ce qui entraine aussi une perte énergétique non négligeable.The disadvantage of known luminaires, as previously described, lies in the fact that their implantation requires the formation of through holes in the partition walls, and their presence in these holes does not provide any seal. Another drawback lies in the fact that optimum illumination requires a large number of luminaires thus multiplying the number of openings to the technical volumes and consequently the importance of airtightness losses. In addition, these luminaires are at the origin of the formation of thermal bridges because of the difference in insulating power between the partition wall and the luminaire, which also entails a significant energy loss.

Il est également connu que les composants électroniques situés à l'arrière de certains luminaires sont exposés à la poussière et à l'humidité, ce qui peut considérablement réduire la durée de vie tant des composants que du luminaire. La partie arrière du luminaire peut, de plus, être exposée à l'action néfaste de quelconques rongeurs se trouvant dans les vides techniques.It is also known that the electronic components on the back of some luminaires are exposed to dust and moisture, which can significantly reduce the life of both the components and the luminaire. The rear part of the luminaire can, moreover, be exposed to the harmful action of any rodents found in the technical voids.

De plus ces luminaires en raison de la chaleur qu'ils dégagent sont à l'origine de la formation d'un halo noir sur la face apparente de la paroi de séparation, autour de la collerette de propreté.In addition, these luminaires because of the heat they give off are at the origin of the formation of a black halo on the apparent face of the partition wall, around the collar of cleanliness.

Enfin, les crochets de fixation du luminaire sont susceptibles de détériorer la paroi lorsqu'elle est en matériau friable de type plâtre.Finally, the fixing brackets of the luminaire are likely to deteriorate the wall when it is plaster-type friable material.

En raison des pertes d'étanchéité générées par leur pose, ces luminaires ne sont pas utilisés dans des bâtiments basse consommation alors qu'actuellement, en raison des progrès réalisés dans le domaine de l'éclairage, sont proposés des luminaires à diodes électroluminescentes à très basse consommation électrique.Due to the leaks generated by their installation, these luminaires are not used in low-energy buildings whereas currently, due to the progress made in the field of lighting, light-emitting diode luminaires are proposed. low power consumption.

Solution technique.Technical solution.

La présente invention a pour but de pallier les inconvénients précédemment évoqués en mettant en oeuvre un équipement d'étanchéité pour luminaire du type précédemment décrit, cet équipement d'étanchéité étant apte à assurer une séparation étanche entre le volume non habitable dans lequel pénètre le luminaire et le volume habitable à éclairer.The object of the present invention is to overcome the drawbacks previously mentioned by implementing a sealing equipment for a luminaire of the type previously described, this sealing equipment being able to ensure a tight separation between the non-habitable volume in which the luminaire penetrates. and the living space to be illuminated.

Une autre but de la présente invention est équipement d'étanchéité pouvant être aisément adaptable sur des luminaires déjà posés.Another object of the present invention is sealing equipment that can be easily adaptable to already installed luminaires.

À cet effet, l'équipement d'étanchéité selon l'invention, prévu pour équiper un luminaire destiné à être encastré dans un perçage traversant formé dans une paroi assurant la séparation entre un volume habitable à éclairer et un vide technique, se caractérise essentiellement en ce qu'il est formé d'une enveloppe formant une chambre étanche à l'air et à l'eau équipée à l'avant d'une ouverture d'introduction du luminaire, ladite enveloppe étant prévue par sa partie arrière pour être engagée dans le vide technique en arrière de la paroi de séparation, et ladite enveloppe présentant des moyens de fixation étanche à ladite paroi et ce à la périphérie de l'orifice traversant.For this purpose, the sealing equipment according to the invention, intended to equip a luminaire intended to be embedded in a through bore formed in a wall ensuring the separation between a habitable volume to be illuminated and a technical vacuum, is essentially characterized by it is formed of an envelope forming an airtight and water-equipped chamber equipped at the front of an opening for introducing the luminaire, said envelope being provided by its rear part to be engaged in the technical vacuum behind the partition wall, and said envelope having sealing means for sealing said wall and the periphery of the through orifice.

Ainsi malgré la présence du luminaire et du perçage traversant pratiqué dans la paroi qui supporte ce luminaire, le volume habitable se trouve parfaitement isolé du volume technique et aucun passage d'air ne s'établir entre ces deux volumes. Par ailleurs le luminaire se trouve physiquement isolé du vide technique et se trouve ainsi protégé des poussières et de l'humidité ainsi que de la déprédation des rongeurs.Thus despite the presence of the luminaire and the piercing piercing practiced in the wall which supports this luminaire, the living space is perfectly isolated from the technical volume and no passage of air is established between these two volumes. In addition, the luminaire is physically isolated from the technical vacuum and is thus protected from dust and moisture as well as the depredation of rodents.

Avantageusement, selon une autre caractéristique de l'invention, l'enveloppe étanche est réalisée en un matériau à faible coefficient de conduction thermique. Cette enveloppe assure donc une isolation thermique entre le volume technique et le volume habitable et assure aussi une isolation thermique entre le luminaire et le vide technique. Les ponts thermiques se trouveront ainsi minimisés.Advantageously, according to another characteristic of the invention, the sealed envelope is made of a material with a low coefficient of thermal conduction. This envelope thus provides thermal insulation between the technical volume and the living space and also provides thermal insulation between the luminaire and the technical vacuum. Thermal bridges will be minimized.

Selon une autre caractéristique de l'invention, l'enveloppe étanche présente une forme de manchon cylindrique par laquelle elle est prévue pour être engagée dans le perçage traversant formé dans la paroi de séparation, ladite forme de manchon étant prévue pour accueillir le support de la lampe, cette forme de manchon cylindrique étant formée entre un épaulement arrière et une collerette avant sous forme de couronne circulaire, ladite collerette avant et ledit épaulement arrière étant respectivement prévus pour venir en appui contre la face apparente de ladite paroi de séparation, ou face avant et contre la face opposée de la dite paroi ou face arrière et ce à la périphérie du perçage traversant, la face interne à l'enveloppe dudit épaulement arrière étant prévu pour recevoir en appui les crochets de fixation du support du luminaire.According to another characteristic of the invention, the sealed envelope has a cylindrical sleeve shape by which it is intended to be engaged in the through bore formed in the partition wall, said sleeve shape being provided to accommodate the support of the lamp, this form of cylindrical sleeve being formed between a rear shoulder and a front flange in the form of a circular ring, said front flange and said rear shoulder being respectively provided to bear against the apparent face of said partition wall, or front face and against the opposite face of said wall or rear face and this at the periphery of the through bore, the inner face of the envelope of said rear shoulder being provided to receive in support of the fixing hooks of the luminaire support.

En raison de cette disposition, le luminaire se trouvera isolé thermiquement de la paroi de séparation qui le supporte, ce qui réduit fortement l'importance des ponts thermiques pouvant être crées entre ces deux éléments.Because of this arrangement, the luminaire will be thermally insulated from the partition wall that supports it, which greatly reduces the importance of the thermal bridges that can be created between these two elements.

Selon une autre caractéristique de l'invention, l'enveloppe présente un perçage traversant de passage d'un câble d'alimentation en énergie électrique de la lampe d'éclairage, ledit perçage étant associé à une membrane d'étanchéité.According to another characteristic of the invention, the casing has a through bore passing through a cable for supplying electrical energy to the lighting lamp, said piercing being associated with a sealing membrane.

Selon une autre caractéristique de l'invention l'enveloppe est réalisée en un matériau souple, élastiquement déformable. Une telle disposition, par déformation de l'enveloppe, permet la mise en place du manchon dans le perçage traversant de la paroi.According to another characteristic of the invention the envelope is made of a flexible material, elastically deformable. Such an arrangement, by deformation of the envelope, allows the establishment of the sleeve in the through hole of the wall.

L'invention a également pour objet un luminaire du type précité caractérisé essentiellement en ce qu'il comporte une enveloppe conforme à l'invention.The subject of the invention is also a luminaire of the aforementioned type essentially characterized in that it comprises an envelope according to the invention.

Selon une autre caractéristique de l'invention, au luminaire est associé une seconde collerette de propreté, disposée entre la collerette de la douille du support de la lampe et la collerette de l'enveloppe étanche, ladite seconde collerette de propreté comportant un logement prévu pour accueillir la collerette de l'enveloppe étanche.According to another characteristic of the invention, the luminaire is associated with a second collar of cleanliness disposed between the collar of the socket of the lamp support and the collar of the sealed envelope, said second collar comprising a housing provided for welcome the collar of the waterproof envelope.

La collerette de propreté vise à protéger la face apparente de la paroi du noircissement formé pour les dispositions antérieures, notamment par des marques d'échauffement résultant habituellement de la chaleur dégagée par l'ampoule et transmise par conduction, par contact direct, à la face apparente de la paroi, par la collerette du support de lampe.The flange is intended to protect the visible face of the blackening wall formed for the prior arrangements, in particular by heating marks usually resulting from the heat generated by the bulb and transmitted by conduction, by direct contact, to the face. apparent from the wall, by the collar of the lamp holder.

Le logement que comporte cette seconde collerette de propreté, permet notamment d'absorber l'épaisseur de la collerette de l'enveloppe afin qu'elle puisse être appliquée contre la face apparente de la paroi. En outre le logement aux formes et dimensions de la collerette de l'enveloppe étanche permet de réaliser le centrage axial de la seconde collerette de propreté par rapport à la lampe et au support.The housing that includes this second flange clean, in particular allows to absorb the thickness of the collar of the envelope so that it can be applied against the apparent face of the wall. In addition, the housing with the shapes and dimensions of the flange of the sealed envelope makes it possible to center the second flange axially in relation to the lamp and the support.

Selon une autre caractéristique de l'invention, la seconde collerette de propreté présente des lignes de prédécoupe en vue de la formation du perçage traversant, les dites lignes formant des cercles concentriques.According to another characteristic of the invention, the second flange has pre-cut lines for the formation of the through hole, said lines forming concentric circles.

On observe en figures 1 et 2 un équipement d'étanchéité 1 prévu pour équiper un luminaire 2 à poser ou bien un luminaire déjà posé, dans la mesure ou ce luminaire peut facilement être déposé de la paroi qui le supporte. Plus précisément, l'équipement d'étanchéité 1 détermine une chambre interne 15 prévue pour recevoir en fixation le luminaire 2. Comme on peut le voir en figure 2, l'ensemble formé par l'équipement d'étanchéité et le luminaire 2, est encastré dans le perçage traversant cylindrique 30 d'une paroi 3 formant par exemple un faux plafond, assurant une séparation entre un volume habitable 4 à éclairer et un vide technique 5.We observe figures 1 and 2 a sealing equipment 1 provided for equipping a luminaire 2 to be installed or a previously installed luminaire, in so far as or this luminaire can easily be removed from the wall that supports it. More specifically, the sealing equipment 1 determines an internal chamber 15 provided for receiving the fixture 2 in fixation. As can be seen in FIG. figure 2 , the assembly formed by the sealing equipment and the luminaire 2, is embedded in the cylindrical through bore 30 of a wall 3 forming for example a false ceiling, ensuring a separation between a living volume 4 to be illuminated and a vacuum technical 5.

Le luminaire 2 comprend un support 20 de lampe, rigide, formé d'une douille tubulaire d'emmanchement 201, de forme cylindrique et d'une collerette de propreté 202, indéformable, ménagée à l'extrémité avant de la douille d'emmanchement 201. l'extrémité avant de la douille est celle tournée vers le volume habitable 4. Ce support de lampe 20 est prévu pour recevoir de manière amovible une lampe d'éclairage 21. Typiquement, une telle lampe 21 comprend une ampoule substantiellement de forme tronconique, dont la petite base est prolongée vers l'arrière par un culot. Le culot est prévu pour être raccordé par un câble électrique C, au réseau de distribution électrique du bâtiment. En vue de la fixation amovible de la lampe 21 au support 20, la douille 201 dudit support 20 présente des joncs élastiques 203 prévus pour être engagés dans une gorge pratiquée dans l'ampoule de la lampe, au niveau de la grande base de ladite lampe. Le support 20, à l'opposé de la collerette de propreté 202, est équipé de crochets élastiques 204 de fixation.The luminaire 2 comprises a lamp support 20, rigid, formed of a tubular sleeve socket 201, of cylindrical shape and a cleanliness collar 202, dimensionally stable, formed at the front end of the fitting sleeve 201 the front end of the socket is that turned towards the habitable volume 4. This lamp support 20 is designed to removably receive a lighting lamp 21. Typically, such a lamp 21 comprises a bulb substantially of frustoconical shape, whose small base is extended towards the rear by a base. The base is intended to be connected by an electric cable C to the electrical distribution network of the building. With a view to the removable fixing of the lamp 21 to the support 20, the socket 201 of said support 20 has elastic rods 203 intended to be engaged in a groove made in the lamp envelope, at the level of the large base of said lamp . The support 20, opposite the cleaning collar 202, is equipped with elastic hooks 204 fixing.

Comme on peut le voir sur les figures 1 et 2, l'équipement d'étanchéité 1 est formé d'une enveloppe déterminant la chambre interne 15. Cette chambre 15 est étanche à l'air et à l'eau. Cette enveloppe 1 est équipée d'une partie avant 13 dotée d'une ouverture 10 d'introduction du luminaire 2, dans la chambre interne 15, l'ouverture 10 formant la partie avant de la chambre interne 15. Les parties avant 13 de l'enveloppe 1 et de la chambre 15 sont celles tournées vers le volume habitable 4. L'enveloppe 1 est dotée d'une partie arrière 16, sous forme de dôme par exemple, et d'une partie centrale 11 se développant entre la partie arrière 16 et la partie avant 13. La chambre 15 est formée dans la partie arrière 16, dans la partie centrale 11 et dans la partie avant 13.As can be seen on the figures 1 and 2 , the sealing equipment 1 is formed of an envelope defining the internal chamber 15. This chamber 15 is airtight and watertight. This envelope 1 is equipped with a front part 13 provided with an opening 10 for introducing the luminaire 2 into the internal chamber 15, the opening 10 forming the front part of the internal chamber 15. The front parts 13 of the 1 and the chamber 15 are those facing the living space 4. The envelope 1 is provided with a rear portion 16, in the form of a dome for example, and a central portion 11 developing between the rear portion 16 and the front portion 13. The chamber 15 is formed in the rear portion 16, in the central portion 11 and in the front portion 13.

L'enveloppe 1 est réalisée en une matière souple et est formée en toute matière synthétique adaptée, non métallique, élastiquement déformable, présentant un faible coefficient de conduction thermique, et apte à résister à la chaleur pouvant être dégagée par la lampe 21 du luminaire 2.The envelope 1 is made of a flexible material and is formed of any suitable synthetic material, non-metallic, elastically deformable, having a low coefficient of thermal conduction, and able to withstand the heat that can be released by the lamp 21 of the luminaire 2.

L'enveloppe 1 est prévue pour être engagée par sa partie arrière 16 dans le vide technique 5 et par sa partie centrale 11 dans le perçage 30 de la paroi 3, la partie avant 13 de l'enveloppe demeurant à l'extérieur du perçage 30.The casing 1 is designed to be engaged by its rear part 16 in the technical void 5 and by its central portion 11 in the bore 30 of the wall 3, the front portion 13 of the casing remaining outside the bore 30 .

L'enveloppe 1 présente des moyens de fixation étanche à la paroi de séparation 3, et ce à la périphérie du perçage traversant 30 et dans ce dernier. Ces moyens de fixation, outre l'immobilisation de l'enveloppe dans le perçage traversant 30 assurent une étanchéité thermique entre le vide technique 5 et le volume habitable. Ainsi, ces moyens réduisent fortement les transferts de chaleur entre ces deux volumes, ils assurent aussi une étanchéité à l'air, à l'eau, et à la vapeur d'eau.The casing 1 has sealing means for fastening to the partition wall 3, and this at the periphery of the through hole 30 and in the latter. These fixing means, in addition to the immobilization of the casing in the through hole 30 provide a thermal seal between the technical vacuum 5 and the living volume. Thus, these means greatly reduce heat transfer between these two volumes, they also provide a seal to air, water, and water vapor.

Avantageusement, les moyens de fixation de l'enveloppe étanche 1 à la paroi de séparation 3 sont formés par la partie centrale 11 de l'enveloppe 1 et à cette fin, cette partie centrale adopte une forme de manchon cylindrique. Ces moyens sont de plus formés par un épaulement arrière 12 de l'enveloppe, situé entre le manchon 11 et la partie arrière 16 de l'enveloppe et par la partie avant 13 de ladite enveloppe, cette dite partie avant 13 formant une collerette élastiquement déformable, se présentant sous forme de couronne circulaire. Le diamètre de cette collerette, sans que cela soit limitatif est égal au diamètre de la collerette 202, mais il peut être supérieur ou inférieur à ce diamètre.Advantageously, the fixing means of the sealed envelope 1 to the partition wall 3 are formed by the central portion 11 of the casing 1 and for this purpose, this central portion adopts a cylindrical sleeve shape. These means are furthermore formed by a rear shoulder 12 of the casing, located between the sleeve 11 and the rear part 16 of the casing and by the front part 13 of said casing, said front part 13 forming an elastically deformable collar , in the form of a circular crown. The diameter of this collar, without being limiting, is equal to the diameter of the flange 202, but it may be greater or smaller than this diameter.

Comme on peut le voir en figure 2, le manchon 11 se développe entre l'épaulement arrière 12 et la collerette avant 13. L'épaulement arrière 12 et la collerette 13 sont en regard l'un de l'autre et sont respectivement prévus pour venir en appui contre la face arrière de la paroi 3 et contre la face avant ou face apparente de ladite paroi 3 et ce à la périphérie du perçage traversant 30. Le manchon 11 est prévu pour venir dans le perçage traversant 30. Avantageusement, le diamètre externe du manchon cylindrique 11 est identique au diamètre du perçage 30. Ainsi ce manchon 11, par sa surface cylindrique externe, vient contre la face cylindrique du perçage 30. Cette disposition vise à améliorer l'étanchéité réalisée par l'enveloppe 1 entre le vide technique et le volume à éclairer.As we can see in figure 2 , the sleeve 11 develops between the rear shoulder 12 and the front flange 13. The rear shoulder 12 and the flange 13 are opposite one another and are respectively provided to bear against the rear face of the the wall 3 and against the front face or apparent face of said wall 3 and this at the periphery of the through hole 30. The sleeve 11 is provided to come into the through bore 30. Advantageously, the outer diameter of the cylindrical sleeve 11 is identical to the diameter of the bore 30. Thus this sleeve 11, by its outer cylindrical surface, comes against the cylindrical face of the bore 30. This provision is to improve the seal made by the casing 1 between the technical vacuum and the volume to be illuminated.

L'épaulement arrière 12 prend la forme d'une couronne circulaire. Cet épaulement en prenant appui sur la totalité de la périphérie du perçage 30 renforce l'étanchéité assurée par l'enveloppe 1 entre le vide technique et 5 et le volume 4 à éclairer.The rear shoulder 12 takes the form of a circular crown. This Shoulder bearing on the entire periphery of the bore 30 reinforces the sealing provided by the casing 1 between the technical vacuum and 5 and the volume 4 to be illuminated.

Avantageusement, la partie arrière 16 de l'enveloppe 1, est équipée d'au moins un perçage traversant 14 obturé par une membrane d'étanchéité 14a. Par ce perçage traversant 14, le câble d'alimentation C en énergie électrique est engagé dans la chambre interne 15 de l'enveloppe 1 en vue d'être connecté électriquement au culot de la lampe 21.Advantageously, the rear portion 16 of the casing 1, is equipped with at least one through bore 14 closed by a sealing membrane 14a. Through this through hole 14, the power cable C in electrical energy is engaged in the internal chamber 15 of the casing 1 in order to be electrically connected to the base of the lamp 21.

Après montage de l'enveloppe 1 dans le perçage traversant 30 de la paroi 3, le luminaire 2, hormis sa collerette de propreté 202, est engagé dans la chambre 15 de l'enveloppe par passage au travers de l'ouverture 10. La douille 201 du support 20 de lampe est logée dans la dans la forme de manchon 11 de l'enveloppe. Le diamètre externe de la douille 201 est égal ou légèrement inférieur au diamètre interne de la forme de manchon. De cette manière est assurée la coaxialité du support de lampe 20 par rapport au manchon 11 et par voie de conséquence, par rapport au perçage traversant 30. Les crochets 204 que le support 20 de lampe présente, viennent en appui contre l'épaulement arrière 12 et plus précisément contre la face de cet épaulement, interne à l'enveloppe 1. Sous l'effet de l'élasticité des crochets 204, le support de lampe 20 est sollicité vers la partie arrière de l'enveloppe et par sa collerette de propreté 202, est sollicité vers la collerette 13 de ladite enveloppe 1. Sous l'effet de cette sollicitation mécanique, la collerette 13 de l'enveloppe 1 est appliquée contre la paroi 3, épouse les éventuelles inégalités de cette paroi présentes à ce niveau, et forme autour de du perçage 30 de la paroi 3 une barrière d'étanchéité à l'air, notamment. Comme on le comprend les dispositions de crochets 204 et de collerette de propreté 202 assurent la fixation et l'immobilisation du luminaire dans l'enveloppe étanche 1.After assembly of the casing 1 in the through hole 30 of the wall 3, the luminaire 2, apart from its flange 202, is engaged in the chamber 15 of the casing by passing through the opening 10. The socket 201 of the lamp holder 20 is housed in the sleeve 11 of the casing. The outer diameter of the sleeve 201 is equal to or slightly less than the inside diameter of the sleeve shape. In this way is ensured the coaxiality of the lamp holder 20 with respect to the sleeve 11 and consequently with respect to the through hole 30. The hooks 204 that the lamp support 20 present, bear against the rear shoulder 12 and more precisely against the face of this shoulder, internal to the casing 1. Under the effect of the elasticity of the hooks 204, the lamp holder 20 is biased towards the rear part of the casing and by its flange cleanliness 202, is biased towards the flange 13 of said casing 1. Under the effect of this mechanical stress, the flange 13 of the casing 1 is applied against the wall 3, matches the possible unevenness of this wall present at this level, and form around the bore 30 of the wall 3 an airtight barrier, in particular. As is understood, the provisions of hooks 204 and flange 202 provide fixing and immobilization of the luminaire in the sealed envelope 1.

Selon une forme de réalisation, la collerette de propreté 202, sous l'effet de l'élasticité des crochets 13 et du mouvement d'enfoncement du support 20 dans le manchon 11 de l'enveloppe, prend appui contre la collerette 13 de l'enveloppe et comprime cette dernière contre la paroi 3, mais selon une forme préférée de réalisation, elle prend appui contre une seconde collerette de propreté 22. Cette collerette de propreté 22, amovible, est interposée entre la collerette 202 du support 20 et la collerette avant 13 de l'enveloppe 1. Sous l'effet de l'élasticité des crochets 204 et de la sollicitation d'enfoncement du support 20 dans le manchon 11, ledit support 20, par sa collerette de propreté 202, est amené contre la collerette de propreté 22 et cette collerette 22 sous l'effet de cette sollicitation est amenée contre la collerette 13 afin de comprimer cette dernière contre la paroi 3. Comme dit précédemment, sous l'effet de cette compression, la collerette 13 épouse les éventuelles inégalités de la paroi 3 et forme autour du perçage 30 une barrière d'étanchéité.According to one embodiment, the flange 202, under the effect of the elasticity of the hooks 13 and the driving movement of the support 20 in the sleeve 11 of the envelope, bears against the collar 13 of the envelope and compresses the latter against the wall 3, but according to a preferred embodiment, it bears against a second flange 22. This cleanliness collar 22, removable, is interposed between the flange 202 of the support 20 and the front flange 13 of the casing 1. Under the effect of the elasticity of the hooks 204 and the biasing stress of the support 20 in the sleeve 11, said support 20, by its flange of cleanliness 202, is brought against the flange 22 and this flange 22 under the effect of this bias is brought against the flange 13 to compress it against the wall 3. As said before, under the effect of this compression, the collar 13 matches any unevenness of the wall 3 and forms around the bore 30 a sealing barrier.

La collerette 22 sous forme de couronne circulaire, présente un diamètre externe bien supérieur aux diamètres externes des collerettes 20 et 13 et forme autour de l'orifice 30 de la paroi 3, une protection contre le noircissement de la face apparente de cette paroi 3.The flange 22 in the form of a circular ring has an external diameter much greater than the external diameters of the flanges 20 and 13 and forms around the orifice 30 of the wall 3, a protection against blackening of the apparent face of this wall 3.

La collerette 22 est réalisée en un matériau rigide apte à être facilement découpé Avantageusement, collerette 22 est constituée en un matériau à faible coefficient de conduction thermique tel que matière plastique et autre. Ainsi cette collerette renforce l'isolation thermique entre la paroi 3 et le luminaire.The flange 22 is made of a rigid material capable of being easily cut. Advantageously, flange 22 is made of a material with a low coefficient of thermal conduction, such as plastic material and the like. Thus this collar reinforces the thermal insulation between the wall 3 and the luminaire.

La collerette 22 présente un perçage central traversant 225 par lequel elle est enfilée sur la douille 201 du support 20. Le diamètre de ce perçage traversant 225 est ajusté au diamètre externe de la douille 201 et est légèrement supérieur à ce diamètre.The flange 22 has a central piercing 225 through which it is threaded on the sleeve 201 of the support 20. The diameter of this through hole 225 is adjusted to the outer diameter of the sleeve 201 and is slightly greater than this diameter.

En vue de faciliter son adaptation aux divers diamètres de douille, la seconde collerette de propreté pourra présenter des lignes 221 de prédécoupe formant des cercles concentriques. Le perçage traversant sera formé par enlèvement des parties prédécoupées correspondantes au diamètre choisi.In order to facilitate its adaptation to the various diameters of the sleeve, the second flange may have pre-cut lines 221 forming concentric circles. The through hole will be formed by removing the precut parts corresponding to the chosen diameter.

Avantageusement, autour du perçage traversant, la seconde collerette 22 présente un logement 220 sous forme de lamage prévu pour accueillir la collerette avant 13 de l'enveloppe 1. La profondeur de ce logement correspond sensiblement à l'épaisseur de la collerette 13, de préférence légèrement inférieur à cette épaisseur pour pouvoir réaliser un effet de compression de ladite collerette 13 contre la paroi 3. Le diamètre de ce logement 220 sera égal ou légèrement supérieur au diamètre de la collerette 13. Grâce à ces dispositions, la seconde collerette de propreté 22, sous l'effet de l'élasticité des crochets 204 et de l'action d'enfoncement du support 20 dans le manchon 11, pourra venir en appui contre la face apparente de la paroi 3 tout en comprimant la collerette 13.Advantageously, around the through hole, the second flange 22 has a housing 220 in the form of counterbore intended to accommodate the front flange 13 of the casing 1. The depth of this housing substantially corresponds to the thickness of the flange 13, preferably slightly less than this thickness to be able to achieve a compression effect of said flange 13 against the wall 3. The diameter of this housing 220 will be equal to or slightly greater than the diameter of the collar 13. With these provisions, the second flange 22 , under the effect of the elasticity of the hooks 204 and the driving action of the support 20 in the sleeve 11, can come into bearing against the apparent face of the wall 3 while compressing the flange 13.

La face apparente de cette seconde collerette de propreté pourra recevoir toutes décorations adaptées en relation avec la décoration du volume habitable.The visible face of this second collar of cleanliness will be able to receive all decorations adapted in relation with the decoration of the habitable volume.

Il va de soi que la présente invention peut recevoir tous aménagements et variantes du domaine des équivalents techniques sans pour autant sortir du cadre du présent brevet tel que défini par les revendications ci-après.It goes without saying that the present invention can receive any arrangements and variants of the field of technical equivalents without departing from the scope of this patent as defined by the claims below.
