Description

La présente invention concerne un luminaire que l'on peut au moins partiellement encastrer dans une cloison sèche.The present invention relates to a luminaire that can be at least partially embedded in a drywall.

Dans certains locaux, par exemple des écoles ou des hôpitaux, il est parfois demandé d'encastrer des luminaires disposés en applique dans la paroi qui les porte. Ceci suppose de nombreuses contraintes. Il faut tout d'abord avoir un luminaire peu encombrant. Il faut ensuite, pour des raisons de sécurité, respecter la protection coupe-feu de la paroi.In some premises, for example schools or hospitals, it is sometimes required to embed luminaires arranged in wall in the wall that carries them. This assumes many constraints. First of all, you need a space-saving luminaire. It is then necessary, for safety reasons, to respect the fire protection of the wall.

Actuellement, peu de luminaires peuvent être encastrés. Les luminaires connus sont de forme sensiblement parallélépipédique avec des bords éventuellement arrondis de manière à présenter une face avant de forme allongée et arrondie aux extrémités. Pour poser un tel luminaire, un trou de forme correspondante est découpé dans la cloison et le luminaire est introduit par translation dans l'ouverture réalisée. La forme de l'ouverture correspond sensiblement à la forme de la section du luminaire.Currently, few luminaires can be recessed. The known luminaires are of substantially parallelepipedal shape with possibly rounded edges so as to have an elongated front face and rounded at the ends. To install such a luminaire, a hole of corresponding shape is cut in the partition and the luminaire is introduced by translation into the opening made. The shape of the opening corresponds substantially to the shape of the section of the luminaire.

Le principal problème technique rencontré avec les luminaires encastrés de l'art antérieur est un problème d'échauffement du luminaire à l'intérieur de la cloison. En effet, l'espace intérieur de la cloison n'étant pas ventilé, le luminaire a tendance à s'échauffer.The main technical problem encountered with the recessed luminaires of the prior art is a problem of heating of the luminaire inside the partition. Indeed, the interior space of the partition is not ventilated, the luminaire tends to heat up.

La présente invention a alors pour but de fournir un luminaire pouvant être encastré pour lequel l'échauffement à l'intérieur de la cloison est limité, même lorsque l'espace pour loger le luminaire est restreint.The object of the present invention is therefore to provide a recessed luminaire for which heating inside the partition is limited, even when the space for accommodating the luminaire is restricted.

A cet effet, elle propose un luminaire destiné à être au moins partiellement encastré dans une cloison sèche comportant une face avant destinée à se trouver au niveau de la surface extérieure de la cloison ainsi qu'un boîtier destiné à être encastré dans la cloison par une ouverture réalisée préalablement dans celle-ci.For this purpose, it proposes a luminaire intended to be at least partially embedded in a drywall having a front face intended to be at the outer surface of the partition and a housing intended to be embedded in the partition by a opening made previously in this one.

Selon l'invention, le boîtier encastré du luminaire, dans sa position installée dans la cloison, présente une partie en saillie venant se loger face à la cloison, à l'intérieur de celle-ci et sur un côté de l'ouverture, et la partie en saillie présente, du côté opposé à la face avant du luminaire, une face de forme profilée arrondie.According to the invention, the recessed housing of the luminaire, in its installed position in the partition, has a protruding part which is lodged in front of the partition, inside the partition and on one side of the opening, and the projecting portion has, on the opposite side to the front face of the luminaire, a face of rounded profiled shape.

Le document DE-A-2107681 présente un luminaire avec une partie en saillie.The document DE-A-2107681 presents a luminaire with a projecting part.

Cette partie en saillie permet d'augmenter la surface d'échange thermique entre le luminaire et son environnement. La chaleur dégagée par le luminaire lors de son fonctionnement s'évacue mieux, limitant ainsi l'échauffement du luminaire. La forme de la saillie permet quant à elle l'introduction du boîtier dans une cloison même dans le cas d'un espace restreint (notamment en profondeur) pour accueillir ce boîtier.This projecting part makes it possible to increase the exchange surface between the luminaire and its environment. The heat released by the luminaire during its operation is evacuated better, thus limiting the heating of the luminaire. The shape of the projection allows for the introduction of the housing in a partition even in the case of a restricted space (including depth) to accommodate this housing.

Dans une forme de réalisation, la partie en saillie présente par exemple, du côté de la face avant du luminaire, une face sensiblement plane et sensiblement parallèle à cette face avant.In one embodiment, the projecting portion has, for example, on the side of the front face of the luminaire, a substantially flat face and substantially parallel to this front face.

Pour faciliter l'introduction du boîtier à travers l'ouverture réalisée dans la cloison, le bord du boîtier à encastrer opposé à la face avant du luminaire et opposé à la partie en saillie, est de préférence arrondi.To facilitate the introduction of the housing through the opening made in the partition, the edge of the recessed housing opposite the front face of the luminaire and opposite the projection, is preferably rounded.

Pour permettre aussi une dissipation de chaleur par convection, la partie en saillie est avantageusement ajourée sur au moins une partie de sa surface.To also allow a heat dissipation by convection, the projecting portion is advantageously perforated on at least a portion of its surface.

L'accès à l'intérieur du luminaire, et notamment de son boîtier, est permis par exemple grâce à une ouverture réalisée sur la partie en saillie. Dans ce cas, on peut prévoir que la face de la partie en saillie opposée à la face avant du luminaire est constituée par un capot amovible.Access to the interior of the luminaire, including its housing, is allowed for example through an opening made on the projecting portion. In this case, it can be provided that the face of the protruding portion opposite the front face of the luminaire is constituted by a removable cover.

Dans une variante de réalisation, la face avant du luminaire est sensiblement rectangulaire et la partie en saillie s'étend sur un grand côté de cette face avant, sur plus de la moitié de la longueur de ce grand côté.In an alternative embodiment, the front face of the luminaire is substantially rectangular and the protruding portion extends over a long side of this front face, over more than half the length of this long side.

La hauteur de la partie en saillie correspond par exemple sensiblement à la hauteur de la face avant du luminaire pour obtenir un bon échange thermique dans la cloison entre le luminaire et son environnement.The height of the protruding portion corresponds for example substantially to the height of the front face of the luminaire to obtain a good heat exchange in the partition between the luminaire and its environment.

De toute manière, les détails et avantages de la présente invention ressortiront mieux de la description qui suit, faite en référence au dessin schématique annexé sur lequel :

  • Figure 1 est une vue en perspective d'un luminaire selon l'invention,
  • Figure 2 est une vue en coupe d'une cloison sur laquelle a été rapporté en vue de côté le luminaire de la figure 1 dans une première position au cours du montage de ce luminaire, et
  • Figures 3 à 6 correspondent à la figure 2 dans des positions successives lors du montage du luminaire.
In any case, the details and advantages of the present invention will become more apparent from the description which follows, given with reference to the appended schematic drawing in which:
  • Figure 1 is a perspective view of a luminaire according to the invention,
  • Figure 2 is a sectional view of a partition on which was reported in side view the luminaire of the figure 1 in a first position during the assembly of this luminaire, and
  • Figures 3 to 6 correspond to the figure 2 in positions successive stages when mounting the luminaire.

La figure 1 montre un luminaire 2 destiné à être encastré dans une cloison 4. Cette dernière peut être une cloison verticale ou bien horizontale dans le cas où il s'agit d'un plafond. L'invention est toutefois plus particulièrement orientée vers les luminaires encastrés dans une cloison verticale, ou mur, car c'est dans ce cas que les problèmes d'échauffement du luminaire apparaissent généralement. En effet, la ventilation au niveau des plafonds est meilleure que dans les cloisons verticales. Dans le cas présent, il s'agit d'une cloison 4 sèche verticale.The figure 1 shows a luminaire 2 intended to be embedded in a partition 4. The latter may be a vertical partition or horizontal in the case where it is a ceiling. The invention is however more particularly directed to the luminaires embedded in a vertical partition, or wall, because it is in this case that the heating problems of the luminaire generally appear. Indeed, the ventilation at the ceilings is better than in the vertical partitions. In this case, it is a vertical dry partition 4.

Le luminaire 2 comporte une face avant 6, un boîtier 8, fermé par la face avant 6, et une partie saillante 10.The luminaire 2 comprises a front face 6, a housing 8, closed by the front face 6, and a projecting portion 10.

La face avant 6 est de forme sensiblement rectangulaire. Sur les figures 2 à 6, on ne voit qu'un petit côté de ce rectangle. Cette face avant 6 comporte notamment une zone transparente ou translucide entourée par un bord opaque. Cette face avant 6 est la partie du luminaire qui restera visible une fois celui-ci encastré. Sa forme dépend de l'esthétique que l'on souhaite donner au luminaire.The front face 6 is of substantially rectangular shape. On the Figures 2 to 6 we only see a small side of this rectangle. This front face 6 comprises in particular a transparent or translucent zone surrounded by an opaque edge. This front face 6 is the part of the luminaire that will remain visible once it is recessed. Its shape depends on the aesthetics that one wishes to give to the luminaire.

Le boîtier 8 est disposé derrière la face avant 6. Il contient de préférence tous les divers composants électriques nécessaires au fonctionnement du luminaire 2. Ces composants, connexions, ampoules, etc... sont connus de l'homme du métier et ne sont pas décrits plus en détails ici. Ils dépendent notamment du type d'ampoule utilisé.The housing 8 is disposed behind the front face 6. It preferably contains all the various electrical components necessary for the operation of the luminaire 2. These components, connections, bulbs, etc ... are known to those skilled in the art and are not described in more detail here. They depend in particular on the type of bulb used.

Ce boîtier 8 est sensiblement parallélépipédique et sa taille est adaptée aux dimensions de la face avant et à la profondeur disponible pour l'encastrement du luminaire. Les longueur et largeur de ce boîtier sont légèrement inférieures aux longueur et largeur de la face avant. Ainsi, la face avant forme un rebord 12 sur au moins deux côtés du boîtier.This housing 8 is substantially parallelepipedal and its size is adapted to the dimensions of the front face and the depth available for the installation of the luminaire. The length and width of this housing are slightly less than the length and width of the front panel. Thus, the front face forms a flange 12 on at least two sides of the housing.

La partie saillante 10 s'étend à partir d'une face du boîtier 8 correspondant à un grand côté de la face avant 6. Cette partie saillante s'étend parallèlement à la face avant 6 et sur quasiment toute la longueur de la face correspondante du boîtier 8. Ainsi, en regardant le luminaire de face, la face avant 6 cache le boîtier 8 et on aperçoit la partie saillante 10 dépasser du contour de la face avant. La hauteur de la partie saillante qui dépasse par rapport à la face avant 6 correspond par exemple sensiblement à la largeur du rectangle formant cette face avant. Cette partie saillante 10 est de préférence sensiblement vide. Comme indiqué plus haut, les composants nécessaires au fonctionnement du luminaire se trouvent dans le boîtier 8. Seuls éventuellement des câbles d'alimentation (non représentés) passent à l'intérieur de la partie saillante 10.The protruding portion 10 extends from a face of the housing 8 corresponding to a large side of the front face 6. This projecting portion extends parallel to the front face 6 and over almost the entire length of the corresponding face of the Thus, by looking at the luminaire from the front, the front face 6 conceals the housing 8 and the projecting portion 10 can be seen protruding from the outline of the front face. The height of the projection protruding from the front face 6 corresponds for example substantially to the width of the rectangle forming this front face. This projecting portion 10 is preferably substantially empty. As indicated above, the components necessary for the operation of the luminaire are in the housing 8. Only possibly power cables (not shown) pass inside the projecting portion 10.

La face arrière du luminaire, par opposition à la face avant 6, est convexe. Les deux bords de l'ensemble formé par le boîtier 8 et la partie saillante 10, s'étendant parallèlement aux grands côtés du rectangle de la face avant 6 sont en fait arrondis pour faciliter le montage du luminaire 2 dans la cloison 4. Pour faciliter la dissipation de chaleur lorsque le luminaire est allumé, la face arrière du luminaire est ajourée au niveau de la partie saillante 10. De l'air peut ainsi circuler à l'intérieur de cette saillie. La face arrière de cette partie saillante 10, c'est-à-dire la face arrondie opposée à la face avant 6, est constituée d'un capot amovible 14. Ce dernier est par exemple fixé d'une part par deux griffes coopérant avec un bord du boîtier 8 et d'autre part par deux tétons venant s'encliqueter sur la face avant de la partie saillante 10. Toute autre fixation du capot peut-être envisagée. Ce capot 14 est prévu pour permettre l'accès à l'intérieur du boîtier 8 pour réaliser par exemple des connexions à l'intérieur de celui-ci avant son montage. Cet accès est facilité par l'absence de composants au niveau de la partie saillante 10.The rear face of the luminaire, as opposed to the front face 6, is convex. The two edges of the assembly formed by the housing 8 and the projecting portion 10, extending parallel to the long sides of the rectangle of the front face 6 are in fact rounded to facilitate the mounting of the luminaire 2 in the partition 4. To facilitate heat dissipation when the luminaire is switched on, the rear face of the luminaire is perforated at the projecting portion 10. Air can thus circulate inside this projection. The rear face of this projecting portion 10, that is to say the rounded face opposite to the front face 6, consists of a removable cover 14. The latter is for example fixed on the one hand by two claws cooperating with an edge of the housing 8 and secondly by two pins coming snap on the front face of the projecting portion 10. Any other fastening hood can be considered. This cover 14 is provided to allow access to the inside of the housing 8 to make connections, for example, inside of the latter before it is mounted. This access is facilitated by the absence of components at the projecting portion 10.

Le montage du luminaire 2 dans la cloison 4 est alors effectué par exemple selon le mode opératoire décrit ci-après en référence aux figures 2 à 6.The mounting of the luminaire 2 in the partition 4 is then carried out for example according to the procedure described hereinafter with reference to FIGS. Figures 2 to 6 .

Une première étape, non représentée au dessin, consiste à réaliser une ouverture 16 dans l'une des deux parois 18 de la cloison 4. On suppose ici que la cloison sèche dans laquelle est posée le luminaire 2 comporte deux parois parallèles 18 reliées entres elles par divers moyens, par exemple un alvéolage en carton. Les parois 18 sont par exemple réalisées en plâtre. A titre d'exemple numérique non limitatif, les parois 18 ont par exemple une épaisseur de 13 ou 15 mm tandis que l'espace libre entre ces deux parois 18 est de 48 mm.A first step, not shown in the drawing, consists in making an opening 16 in one of the two walls 18 of the partition 4. It is assumed here that the drywall in which the luminaire 2 is placed has two parallel walls 18 connected to each other. by various means, for example a cardboard honeycomb. The walls 18 are for example made of plaster. As a non-limiting numerical example, the walls 18 have for example a thickness of 13 or 15 mm while the free space between these two walls 18 is 48 mm.

Pour réaliser l'ouverture 16, on utilise par exemple une scie à cloche. L'ouverture 16 réalisée est d'une taille correspondant à celle du boîtier 8. La taille de cette ouverture est inférieure à celle de la face avant 6. En effet, une fois le luminaire en place, le bord de l'ouverture 16 ne doit plus être apparent mais caché par le rebord 12.To make the opening 16, for example, a hole saw is used. The opening 16 produced is of a size corresponding to that of the housing 8. The size of this opening is smaller than that of the front face 6. Indeed, once the luminaire in place, the edge of the opening 16 must not be visible but hidden by the flange 12.

Pour introduire le luminaire 2 dans la cloison 4 en passant à travers l'ouverture 16, le luminaire est présenté dans la position représentée sur la figure 2. La face avant 6 se trouve alors sensiblement perpendiculaire à la cloison 4 et la partie saillante 10 est introduite dans l'ouverture 16.In order to introduce the luminaire 2 into the partition 4 by passing through the opening 16, the luminaire is presented in the position shown in FIG. figure 2 . The front face 6 is then substantially perpendicular to the partition 4 and the projecting portion 10 is introduced into the opening 16.

L'introduction du luminaire dans la cloison 4 résulte alors d'un mouvement hélicoïdal qui est la combinaison d'une translation du luminaire 2 vers l'intérieur de la cloison 4 et d'un pivotement de l'ensemble du luminaire autour d'un axe perpendiculaire au plan du dessin dans le sens des aiguilles d'une montre. Il est rappelé ici que le plan du dessin correspond à un plan perpendiculaire à la face avant 6 du luminaire 2.The introduction of the luminaire into the partition 4 then results from a helical movement which is the combination of a translation of the luminaire 2 towards the interior of the partition 4 and a pivoting of the entire luminaire around a axis perpendicular to the plane of the drawing in the direction of clockwise. It is recalled here that the plane of the drawing corresponds to a plane perpendicular to the front face 6 of the luminaire 2.

La figure 3 montre le luminaire lorsque la face avant 6 est inclinée d'environ 45° par rapport à la cloison 4. La face avant de la partie saillante 10 est au contact ou quasiment au contact du bord supérieur de l'ouverture 16. On suppose ici que la cloison 4 est une cloison verticale et que le luminaire doit être monté de telle sorte que les grands côtés du rectangle de la face avant 6 soient, en position montée, sensiblement horizontaux. On suppose également que dans ce cas, la partie saillante 10 se trouve au-dessus du boîtier 8. Sur cette figure 3, on constate que le bord arrondi arrière de la partie saillante 10 se rapproche de la paroi 18 ne présentant pas d'ouverture 16. Le bord arrondi arrière du boîtier 8 se trouve quant à lui au niveau du bord inférieur de l'ouverture 16. La présence de ces bords arrondis facilite le passage du luminaire 2 à travers l'ouverture 16 et permet l'installation d'un luminaire de dimensions plus importantes qu'avec des bords à angles droits pour une ouverture de mêmes dimensions.The figure 3 shows the luminaire when the front face 6 is inclined by approximately 45 ° with respect to the partition 4. The front face of the projecting portion 10 is in contact or almost in contact with the upper edge of the opening 16. It is assumed here that the partition 4 is a vertical partition and the luminaire must be mounted so that the long sides of the rectangle of the front face 6 are, in mounted position, substantially horizontal. It is also assumed that in this case the projecting portion 10 is above the housing 8. On this figure 3 it is found that the rounded rear edge of the projecting portion 10 approaches the wall 18 having no opening 16. The rounded rear edge of the housing 8 is located at the lower edge of the opening 16. The presence of these rounded edges facilitates the passage of the luminaire 2 through the opening 16 and allows the installation of a luminaire of larger dimensions with edges at right angles for an opening of the same dimensions.

Comme on le voit sur les figures 4 à 6, la forme arrondie convexe de la face arrière du luminaire permet, au cours du mouvement d'introduction du luminaire dans la cloison 4, de maintenir cette face arrière sensiblement tangente d'une part à la paroi 18 non munie de l'ouverture 16 au niveau de la partie saillante 10 et d'autre part au bord de l'ouverture 16 au niveau du boîtier 8.As we see on the Figures 4 to 6 the convex rounded shape of the rear face of the luminaire makes it possible, during the movement of introduction of the luminaire into the partition 4, to maintain this rear face substantially tangent on the one hand to the wall 18 not provided with the opening 16 to the level of the projecting portion 10 and secondly at the edge of the opening 16 at the housing 8.

Dans la position finale montée (figure 6) la face arrière du luminaire, tant au niveau de la partie saillante 10 que du boîtier 8, vient au contact, au moins localement, de la paroi 18 non munie de l'ouverture 16. Dans cette position, le rebord 12 vient en application contre le pourtour de l'ouverture 16. Le luminaire 2 occupe alors tout l'espace disponible entre les deux parois 18 de la cloison 4.In the final climb position ( figure 6 ) the rear face of the luminaire, both at the projecting portion 10 and the housing 8, comes into contact, at least locally, with the wall 18 not provided with the opening 16. In this position, the rim 12 comes into application against the periphery of the opening 16. The luminaire 2 then occupies all the space available between the two walls 18 of the partition 4.

Lorsque le luminaire 2 est allumé, un échauffement est induit au niveau du boîtier 8. La partie saillante 10, grâce à sa grande surface d'échange avec l'air ambiant, favorise le refroidissement du boîtier 8. De plus, la présence de jours dans le capot 14 de cette partie saillante 10 favorise la circulation d'air à l'intérieur du luminaire. Un échange de chaleur par convection peut ainsi s'établir. Cet échange est favorisé par l'absence de composants dans la partie saillante 10.When the luminaire 2 is on, a heating is induced at the housing 8. The protruding part 10, thanks to its large exchange surface with the ambient air, promotes the cooling of the housing 8. In addition, the presence of days in the cover 14 of this projecting part 10 promotes the circulation of air inside the luminaire. Convective heat exchange can thus be established. This exchange is favored by the absence of components in the salient part 10.

La présente invention ne se limite pas à la forme de réalisation préférentielle décrite ci-dessus à titre d'exemple non limitatif. Elle s'étend au contraire à toutes les variantes de réalisation à la portée de l'homme du métier dans le cadre des revendications ci-après.The present invention is not limited to the preferred embodiment described above by way of non-limiting example. It extends on the contrary to all variants within the scope of the art within the scope of the claims below.
