Un luminaire comprenant un corps et une platine, selon le préambule ci-dessus, est connu du document EP 0 179 453 . Selon ce document, le luminaire est constitué de deux demi coquilles en forme d'auge, et un rail à section en L supporte les éléments d'installation, ainsi qu'un réflecteur. Le rail est fixé à la partie supérieure de la toiture.A luminaire comprising a body and a plate, according to the preamble above, is known from the document EP 0 179 453 . According to this document, the luminaire consists of two trough-shaped half-shells, and an L-section rail supports the installation elements, as well as a reflector. The rail is attached to the top of the roof.

La demande de brevet DE3442527 décrit un luminaire comportant une platine et un corps, ce corps comprenant une toiture et une vasque. Lorsque la toiture et la vasque sont attachées l'une à l'autre, la platine est maintenue en place d'un côté par la charnière qui la lie à la toiture et de l'autre côté par un verrou solidaire de la platine qui vient se positionner sur une avancée solidaire de la toiture.The patent application DE3442527 describes a luminaire comprising a plate and a body, this body comprising a roof and a basin. When the roof and the basin are attached to each other, the plate is held in place on one side by the hinge which connects to the roof and on the other side by a latch secured to the plate that comes to position oneself on an integral advance of the roof.

Le brevet US 4462068 décrit un luminaire comportant un réflecteur faisant office de platine (une douille est attachée au réflecteur) et un corps, ce corps comprenant une toiture et une vasque. Le réflecteur est contenu dans un joint d'étanchéité qui est fixé sur un rebord de la vasque.The patent US 4462068 describes a luminaire comprising a reflector acting as platinum (a socket is attached to the reflector) and a body, this body comprising a roof and a basin. The reflector is contained in a seal that is attached to a rim of the basin.

Un objet de l'invention est d'alléger le luminaire.An object of the invention is to lighten the luminaire.

A cet effet, la platine est maintenue en place par serrage entre la toiture et la vasque.For this purpose, the plate is held in place by clamping between the roof and the basin.

L'idée de base est donc d'améliorer la rigidité par le maintien réciproque de la platine par le corps et vice versa, ce qui permet d'utiliser des demi coquilles plus minces et d'économiser de la matière.The basic idea is to improve the rigidity by the mutual maintenance of the plate by the body and vice versa, which allows to use thinner half shells and save material.

Avantageusement, la platine est pourvue d'une bordure dont la forme correspond à celle du bord de la toiture et du bord de la vasque de façon à être bien maintenue entre ces deux bords.Advantageously, the plate is provided with a border whose shape corresponds to that of the edge of the roof and the edge of the basin so as to be well maintained between these two edges.

Selon l'invention, les deux parois latérales longitudinales de la toiture possèdent chacune une partie inclinée par rapport à la direction d'amenée de la platine lors de sa mise en place, la bordure de la platine est pourvue d'une partie inclinée en correspondance avec la partie inclinée de la toiture, et la partie inclinée de la platine est appuyée contre la partie inclinée correspondante de la toiture, lorsque la platine est assemblée entre la toiture et la vasque.According to the invention, the two longitudinal side walls of the roof each have a portion inclined relative to the direction of supply of the plate during its introduction, the edge of the platinum is provided with an inclined portion in correspondence with the inclined portion of the roof, and the inclined portion of the plate is pressed against the corresponding inclined portion of the roof, when the plate is assembled between the roof and the basin.

En plus de l'amélioration de rigidité que cette disposition procure, elle permet un meilleur contact thermique entre la platine, qui supporte des éléments dégageant de la chaleur, et le corps qui évacue cette chaleur.In addition to the improved rigidity that this provides, it allows a better thermal contact between the plate, which supports elements releasing heat, and the body that evacuates this heat.

Des dispositions particulières de réalisation apparaissent dans les revendications dépendantes 4 à 6.Particular embodiments of the invention appear in the dependent claims 4 to 6.

Ces aspects de l'invention ainsi que d'autres aspects plus détaillés apparaîtront plus clairement grâce à la description suivante d'un mode de réalisation constituant un exemple non limitatif.These and other more detailed aspects of the invention will become more apparent from the following description of an embodiment as a non-limiting example.

La figure 1 est une vue en coupe transversale d'un luminaire selon l'invention.Figure 1 is a cross sectional view of a luminaire according to the invention.

Le luminaire de la figure 1 comprend un corps qui comporte au moins une première demi coquille 20 appelée "toiture". Elle est munie de moyens de fixation 35 quelconques, connus en soi, à un support non représenté qui peut être un mur, un plafond, etc.The luminaire of Figure 1 comprises a body which comprises at least a first half-shell 20 called "roof". It is provided with any fastening means 35, known per se, to a not shown support which may be a wall, a ceiling, etc.

Une deuxième demi coquille transparente 30 appelée "vasque" est assemblée avec la toiture en position d'utilisation, comme représenté ici sous la toiture 20.A second half transparent shell 30 called "basin" is assembled with the roof in the use position, as shown here under the roof 20.

Chacune des demi coquilles possède des bords en correspondance permettant l'assemblage des demi coquilles l'une à l'autre par leur bords, avec insertion d'un joint élastique 5 dans le cas de luminaires étanches. Des verrous 7 sont placés à intervalles réguliers pour assurer l'accrochage de la vasque sur la toiture.Each of the half-shells has corresponding edges for assembling the half shells to one another by their edges, with insertion of an elastic seal 5 in the case of sealed luminaires. Locks 7 are placed at regular intervals to ensure the attachment of the basin on the roof.

Le luminaire illustré ici en exemple est de forme allongée, muni de tubes fluorescents. La coupe de la figure est une coupe transversale.The luminaire illustrated here as an example is of elongated shape, provided with fluorescent tubes. The section of the figure is a cross section.

Une platine 10 supporte des élément fonctionnels internes du luminaire : entre autres un bloc électrique 15, des douilles 45 pour le montage des tubes fluorescents 25.A plate 10 supports internal functional elements of the luminaire: inter alia an electric block 15, sockets 45 for mounting the fluorescent tubes 25.

La platine 10 est pourvue, au moins de chaque côté sur sa longueur, d'une bordure 2 dont la forme correspond à celle du bord de la toiture 20 et du bord de la vasque 30 de façon à être bien maintenue entre ces deux bords.The plate 10 is provided, at least on each side along its length, a border 2 whose shape corresponds to that of the edge of the roof 20 and the edge of the basin 30 so as to be well maintained between these two edges.

Plus précisément, les deux parois latérales longitudinales de la toiture 20 comprennent chacune au moins une partie 3 inclinée par rapport à la direction d'amenée de la platine lors de sa mise en place c'est-à-dire, sur la figure, inclinée par rapport à la verticale.More specifically, the two longitudinal side walls of the roof 20 each comprise at least one portion 3 inclined relative to the direction of supply of the plate during its introduction, that is to say, in the figure, inclined compared to the vertical.

La platine 10 est pourvue d'une partie pliée et inclinée 2 en correspondance avec la partie inclinée 3 de la toiture, et la partie pliée et inclinée 2 est appuyée contre la partie inclinée correspondante 3 de la toiture, lorsque la platine est, comme ici, assemblée avec la toiture. La partie pliée pourrait aussi être une partie rapportée.The plate 10 is provided with a folded and inclined portion 2 in correspondence with the inclined portion 3 of the roof, and the folded and inclined portion 2 is pressed against the corresponding inclined portion 3 of the roof, when the plate is, as here , assembled with the roof. The folded part could also be a reported part.

La vasque 30 comporte des reliefs 1 saillant vers l'intérieur de façon à pousser la partie 2 de la platine 10 vers la toiture 20.The basin 30 has reliefs 1 projecting inwards so as to push the part 2 of the plate 10 towards the roof 20.

Ainsi donc, la platine est maintenue en place par serrage entre la toiture et la vasque.Thus, the plate is held in place by clamping between the roof and the basin.

Les parois inclinées 3 de la toiture comportent des butées 4 pour limiter l'introduction de la partie 2 de la platine dans la toiture.The inclined walls 3 of the roof comprise stops 4 to limit the introduction of the part 2 of the plate in the roof.

Les butées 4 comportent une partie 6 en forme de crochet pour accrocher le bord supérieur de la partie inclinée 2 de la platine afin d'empêcher la flexion de ce bord 2 vers l'intérieur, ou réciproquement empêcher la flexion du bord 3 vers l'extérieur.The stops 4 comprise a hook-shaped portion 6 for hooking the upper edge of the inclined portion 2 of the plate in order to prevent the bending of this edge 2 inwards, or vice versa, to prevent the bending of the edge 3 towards the plate. outside.

Il doit être clair que le verbe "comprendre" n'exclut pas la présence d'autres étapes ou éléments que ceux listés dans une revendication.It must be clear that the verb "to understand" does not exclude the presence of other steps or elements than those listed in a claim.
