Les pièces d'extrémités portent les douilles (12,13) des tubes et facultativement, un dispositif d'amorçage (14).The subject of the invention is a closed luminaire with fluorescent tubes composed in particular of a body (1), a diffuser (2), and two end pieces (3) as well as sealing means (10, 18) between the body, the diffuser and the end pieces. The end pieces carry the sockets (12, 13) of the tubes and optionally, a priming device (14).

Description

La présente invention concerne un luminaire clos à tubes fluorescents, c'est-à-dire un appareil d'éclairage comprenant essentiellement une coque fixée à un support et renfermant notamment des supports de tubes, les accessoires de ces tubes et un réflecteur, ainsi qu'un diffuseur fermant la coque et diffusant la lumière produite par le ou les tubes.The present invention relates to a closed luminaire with fluorescent tubes, that is to say a lighting apparatus essentially comprising a shell fixed to a support and containing in particular tube supports, the accessories of these tubes and a reflector, as well as '' a diffuser closing the shell and diffusing the light produced by the tube or tubes.

De tels luminaires sont bien connus et désignés souvent comme des luminaires étanches, en raison de ce que des précautions sont prises, à la jonction entre la coque et le diffuseur et aux autres ouvertures de la coque, pour préserver l'intérieur du luminaire des poussières et même du ruissellement des eaux, ce qui permet de les utiliser dans des environnements assez rudes (sous-sols, caves, parkings couverts, etc.).Such luminaires are well known and often designated as watertight luminaires, because of the fact that precautions are taken, at the junction between the shell and the diffuser and at the other openings of the shell, to preserve the interior of the luminaire from dust. and even water runoff, which allows them to be used in fairly harsh environments (basements, cellars, covered parking lots, etc.).

Ces luminaires connus, ne serait-ce qu'en raison de l'étanchéité requise, comprennent généralement une coque creuse dont le bord continu est pourvu d'un joint d'étanchéité et un diffuseur également creux dont le bord continu vient s'appliquer contre le joint de la coque, ainsi que des verrous attachant le diffuseur à la coque. Le réflecteur portant les supports et accessoires de tubes est incorporé dans la coque.These known luminaires, if only because of the required tightness, generally comprise a hollow shell whose continuous edge is provided with a seal and an equally hollow diffuser whose continuous edge is applied against the shell seal, as well as locks attaching the diffuser to the shell. The reflector carrying the tube supports and accessories is incorporated in the shell.

Une telle conception,techniquement satisfaisante, est toutefois relativement onéreuse. En particulier, les différentes pièces doivent être formées ou moulées individuellement. De plus, certaines de ces pièces sont encombrantes, ce qui entraîne des coûts élevés pour le stockage et la livraison.Such a technically satisfactory design is, however, relatively expensive. In particular, the different parts must be formed or molded individually. In addition, some of these parts are bulky, resulting in high costs for storage and delivery.

L'invention a donc pour objet un luminaire d'une conception mieux adaptée aux techniques de fabrication disponibles, d'un moindre coût, par conséquent, et offrant des avantages en ce qui concerne le stockage et l'expédition.The subject of the invention is therefore a luminaire of a design better suited to the available manufacturing techniques, of lower cost, consequently, and offering advantages as regards storage and shipping.

Selon une caractéristique essentielle de l'invention, ce luminaire comprend essentiellement un corps en demi-coquille ouvert à ses deux extrémités, un diffuseur également en demi-coquille et ouvert à ses extrémités, adapté pour compléter ledit corps, deux pièces d'extrémités agencées pour refermer les extrémités d'un corps et d'un diffuseur assemblés, ainsi que des moyens d'étanchéité disposés entre, d'une part, ledit diffuseur et lesdites pièces d'extrémités. Les pièces d'extrémités peuvent être des prolongements dudit corps ou lui sont soudés ou collés ou assemblés par des joints d'étanchéité.According to an essential characteristic of the invention, this luminaire essentially comprises a half-shell body open at its two ends, a diffuser also in half-shell and open at its ends, adapted to complete said body, two pieces of ends arranged for closing the ends of an assembled body and diffuser, as well as sealing means arranged between, on the one hand, said diffuser and said end pieces. The end pieces can be extensions of said body or are welded or glued to it or assembled by seals.

Dans une telle forme de luminaire, le corps et/ou le diffuseur peuvent être deux tronçons de profilés de grande longueur, c'est-à-dire à faible coût. Les pièces d'extrémités seront des pièces moulées relativement petites.In such a form of luminaire, the body and / or the diffuser can be two sections of sections of great length, that is to say at low cost. The end pieces will be relatively small molded pieces.

Selon une autre caractéristique de l'invention, ledit corps et/ou ledit diffuseur ont un profil ouvert. Cela permet de stocker et de transporter des luminaires démontés dont les parties les plus encombrantes sont emboîtées les unes dans les autres.According to another characteristic of the invention, said body and / or said diffuser have an open profile. This makes it possible to store and transport dismantled luminaires, the most bulky parts of which are nested one inside the other.

Selon une autre caractéristique de l'invention, lesdites pièces d'extrémités comprennent une portion qui s'introduit entre le corps et le diffuseur, dont le profil est adapté à celui que présentent ces deux pièces entre elles et qui porte un joint d'étanchéité contre lequel s'appliquent le corps et le diffuseur.According to another characteristic of the invention, said end pieces comprise a portion which is introduced between the body and the diffuser, the profile of which is adapted to that which these two pieces have between them and which carries a seal against which apply the body and the diffuser.

Une telle disposition permet d'écarter le diffuseur du corps du luminaire et donc de l'ouvrir et le refermer après montage.Such an arrangement makes it possible to separate the diffuser from the body of the luminaire and therefore to open and close it after assembly.

Selon une autre caractéristique de l'invention, lesdites pièces d'extrémités portent les supports de tubes et facultativement, un dispositif d'amorçage. L'inductance (ballast) des tubes fluorescents sera fixée au fond dudit corps.According to another characteristic of the invention, said end pieces carry the tube supports and optionally, a priming device. The inductance (ballast) of the fluorescent tubes will be fixed to the bottom of said body.

Selon une autre caractéristique de l'invention, les bords dudit corps et dudit diffuseur sont formés de manière à permettre l'agrafage d'un profilé élastique entourant ces deux bords et les pressant l'un contre l'autre sur toute leur longueur, avec interposition d'un joint d'étanchéité. La configuration de ce profilé et desdits bords est telle qu'elle permette la rotation dudit diffuseur porté par une agrafe laissée en place d'un côté du luminaire, alors que l'agrafe de l'autre côté a été détachée, et par conséquent l'ouverture du luminaire sans que le diffuseur se sépare du corps.According to another characteristic of the invention, the edges of said body and of said diffuser are formed so as to allow the stapling of an elastic profile surrounding these two edges and pressing them one against the other over their entire length, with interposition of a seal. The configuration of this profile and of said edges is such that it allows the rotation of said diffuser carried by a clip left in place on one side of the luminaire, while the clip on the other side has been detached, and consequently l opening of the luminaire without the diffuser separating from the body.

Les différents objets et caractéristiques de l'invention seront maintenant exposés de façon plus détaillée dans la description qui va suivre, faite à titre d'exemple non limitatif, en se reportant aux figures annexées qui représentent :

  • - la figure 1, une vue d'une extrémité d'un exemple de réalisation du luminaire de l'invention, diffuseur fermé ;

The various objects and characteristics of the invention will now be explained in more detail in the description which follows, given by way of nonlimiting example, with reference to the appended figures which represent:
  • - Figure 1, a view of one end of an embodiment of the luminaire of the invention, closed diffuser;
  • - Figure 2, a view of the other end of the luminaire of Figure 1, open diffuser;

La figure 1 représente, de façon schématique, l'extrémité d'un luminaire réalisé selon la présente invention. On y voit les parties essentielles de ce luminaire : un corps 1, un diffuseur 2, une pièce d'extrémité 3, une agrafe 4.FIG. 1 schematically represents the end of a luminaire produced according to the present invention. We can see the essential parts of this fixture: a body 1, a diffuser 2, an end piece 3, a clip 4.

Le corps 1 est une sorte de demi-coquille allongée, ouverte à ses deux extrémités. Dans une forme de réalisation, il peut être obtenu par tronçonnage d'un profilé en acier pourvu d'un revêtement anti-corrosion, formé en continu à partir d'une feuille d'acier. Ce revêtement peut être en "Aluzinc", produit entre autre par le fabricant Bethlehem Steel, qui offre l'avantage d'être réfléchissant. Le luminaire n'aura ainsi pas besoin de comprendre un réflecteur, ce qui diminue donc son prix de revient.The body 1 is a kind of elongated half-shell, open at its two ends. In one embodiment, it can be obtained by cutting a steel profile provided with an anti-corrosion coating, formed continuously from a steel sheet. This coating can be in "Aluzinc", produced among others by the manufacturer Bethlehem Steel, which offers the advantage of being reflective. The luminaire will thus not need to include a reflector, which therefore reduces its cost price.

Le diffuseur 2 est de même une sorte de demi-coquille ouverte à ses deux extrémités, qui peut être obtenu par tronçonnage d'un profilé extrudé en une matière plastique transparente ou translucide, telle qu'un polycarbonate.The diffuser 2 is likewise a kind of half-shell open at its two ends, which can be obtained by cutting off an extruded profile in a transparent or translucent plastic material, such as a polycarbonate.

Ces deux pièces, assemblées face à face, forment une sorte de tube ouvert, qui est complété, à chacune de ses extrémités, par une pièce d'extrémité telle que 3, dont la forme est adaptée au profil de cet ensemble, qu'elle coiffe et referme.These two pieces, assembled face to face, form a kind of open tube, which is completed, at each of its ends, by an end piece such as 3, the shape of which is adapted to the profile of this set, which it cap and close.

L'assemblage des deux pièces longitudinales du luminaire, 1 et 2, est réalisé au moyen d'agrafes 4, une de chaque côté.The two longitudinal parts of the luminaire, 1 and 2, are assembled using staples 4, one on each side.

La figure 2 illustre l'autre extrémité du luminaire de la figure 1, mais avec le diffuseur en position d'ouverture, ce qui permet d'en voir l'intérieur. En particulier, une inductance 6 est partiellement visible. Elle est fixée au fonds du corps 1, par exemple par des rivets étanches 7, en bon contact thermique avec le corps 1 pour un meilleur refroidissement.Figure 2 illustrates the other end of the fixture of Figure 1, but with the diffuser in the open position, which allows you to see the inside. In particular, an inductor 6 is partially visible. It is fixed to the bottom of the body 1, for example by waterproof rivets 7, in good thermal contact with the body 1 for better cooling.

L'agrafe 4, qui sera décrite ultérieurement, est telle que, lorsqu'elle est en place, elle permette le pivotement du diffuseur et l'ouverture du luminaire. Dégagée, elle resteattachée au diffuseur comme on peut le voir à la partie inférieure de la figure 2.The clip 4, which will be described later, is such that, when in place, it allows the pivoting of the diffuser and the opening of the luminaire. Unobstructed, it remains attached to the diffuser as can be seen in the lower part of Figure 2.

La pièce d'extrémité 3 comprend un rebord 5 et une paroi latérale 8, visibles aussi sur la figure 1 ; elle comprend également une bordure intérieure 9, sur laquelle est fixée, par exemple par collage, un joint d'étanchéité 10. Une paroi transversale 11 porte également deux douilles 12 et 13, par exemple des supports classiques d'extrémité de tubes fluorescents. L'une d'entre elles peut être une douille combinée comportant un dispositif d'amorçage 14.The end piece 3 comprises a flange 5 and a side wall 8, also visible in FIG. 1; it also includes an inner edge 9, on which is fixed, for example by gluing, a seal 10. A transverse wall 11 also carries two sockets 12 and 13, for example conventional end supports of fluorescent tubes. One of them may be a combined socket comprising a priming device 14.

Lorsque le diffuseur 2 est relevé, pour prendre la position illustrée par la figure 1, sa paroi intérieure, au voisinage de son extrémité, vient s'appliquer contre le joint 10 de la pièce d'extrémité 3, le profil du diffuseur et celui de la bordure intérieure 9 étant adaptés pour qu'il en résulte une fermeture étanche.When the diffuser 2 is raised, to take the position illustrated in FIG. 1, its inner wall, in the vicinity of its end, is applied against the seal 10 of the end piece 3, the profile of the diffuser and that of the inner edge 9 being adapted so that a tight closure results.

Cet aspect est plus complètement illustré par la figure 3 qui représente une vue en coupe transversale du luminaire dans laquelle, pour simplifier, on n'a pas représenté le contenu du luminaire (tubes, leurs supports, etc.).This aspect is more fully illustrated by FIG. 3 which represents a cross-sectional view of the luminaire in which, for simplicity, the content of the luminaire has not been represented (tubes, their supports, etc.).

On y retrouve le corps 1 dont le profil évasé, du coude 15 au coude 16, est prolongé par deux bords identiques comprenant une première partie 17 portant un joint d'étanchéité longitudinal 18 et une seconde partie 19 retournée en forme de crochet. Le profil de ce corps 1 est relativement ouvert, de sorte que le stockage ou le transport de luminaires sera facilité par le fait que l'on peut en emboîter un grand nombre pour les réunir sous un faible volume. La bordure interne 9 de- la pièce d'extrémité 3 comprend une partie 20 épousant le profil du corps 1 et portant le joint d'étanchéité 10, tout comme la partie visible sur la figure 2. Le corps 1 est ainsi plaqué contre le joint qui assure l'étanchéité entre celui-ci et la pièce d'extrémité 3, jusqu'au niveau du joint longitudinal 18.We find there the body 1 whose flared profile, from the elbow 15 to the elbow 16, is extended by two identical edges comprising a first part 17 carrying a longitudinal seal 18 and a second part 19 returned in the form of a hook. The profile of this body 1 is relatively open, so that the storage or transport of luminaires will be facilitated by the fact that a large number of them can be fitted together in a small volume. The internal border 9 of the end piece 3 comprises a part 20 conforming to the profile of the body 1 and carrying the seal 10, just like the part visible in FIG. 2. The body 1 is thus pressed against the seal which seals between the latter and the end piece 3, up to the level of the longitudinal joint 18.

Au-delà du joint 18, la partie 21 de la bordure 9 épouse la forme du profil du diffuseur 2 qui, lorsqu'il est agrafé au corps 1 vient également se plaquer sur le joint 10, de sorte qu'effectivement la bordure interne 9 de la pièce d'extrémité 3 est disposée avec une étanchéité complète à l'intérieur de la structure tubulaire formée par le corps 1 et le diffuseur 2. La liaison longitudinale entre les bords du corps 1 et du diffuseur 2 comprend un joint 18 de chaque côté du luminaire, de sorte que l'intérieur du luminaire est efficacement protégé du milieu extérieur.Beyond the seal 18, the part 21 of the border 9 follows the shape of the profile of the diffuser 2 which, when stapled to the body 1 also comes to be pressed against the seal 10, so that effectively the internal border 9 of the end piece 3 is arranged with a complete seal inside the tubular structure formed by the body 1 and the diffuser 2. The longitudinal connection between the edges of the body 1 and of the diffuser 2 comprises a seal 18 of each side of the luminaire, so that the interior of the luminaire is effectively protected from the outside environment.

Pour être complet, on peut encore mentionner que les pièces d'extrémités 3 comprennent aussi un orifice d'entrée de câble (22) qui sera aussi doté de moyens d'étanchéité.To be complete, we can also mention that the pieces of ex hoppers 3 also include a cable entry orifice (22) which will also be provided with sealing means.

La figure 4 illustre le mode d'assemblage d'une pièce d'extrémité 3 au corps 1 et au diffuseur 2. On y voit, vue en coupe, la pièce d'extrémité 3, en forme de coupe à fond plat, la paroi latérale 8, prolongée à angle droit par la bordure intérieure 9 et, à l'extérieur de celle-ci, avec un raccord arrondi, par le rebord 5. On a déjà examiné la bordure 9 qui porte le joint 10. On peut encore ajouter que cette bordure comprend aussi, venues de moulage, des pattes 23,24 ayant un double rôle : retenir le joint 10 en position et éviter l'écrasement de celui-ci. A cette fin ces pattes, disposées par paires tout autour de la bordure (voir figure 3) ont une - hauteur inférieure à l'épaisseur du joint 10. Le rebord 5 comprend, intérieurement, des pattes d'accrochages 25, élastiques, prévues pour s'engager dans des ouvertures pratiquées au voisinage de l'extrémité du corps 1. Ces ouvertures seront de préférence réalisées au cours de l'opération de tronçonnage du profilé à partir duquel est obtenu le corps 1.FIG. 4 illustrates the method of assembling an end piece 3 to the body 1 and to the diffuser 2. There is seen, in section view, the end piece 3, in the form of a cup with a flat bottom, the wall lateral 8, extended at right angles by the inner border 9 and, outside of this, with a rounded connection, by the flange 5. We have already examined the border 9 which carries the seal 10. It is also possible to add that this border also comprises, coming from molding, lugs 23, 24 having a double role: retaining the seal 10 in position and preventing it from being crushed. To this end, these tabs, arranged in pairs all around the edge (see FIG. 3) have a height less than the thickness of the joint 10. The flange 5 comprises, internally, snap tabs 25, elastic, provided for engage in openings in the vicinity of the end of the body 1. These openings will preferably be made during the cutting operation of the profile from which the body 1 is obtained.

La pièce d'extrémité 3 est donc fixée au corps 1 qui s'engage entre la bordure intérieure 9, par-dessus le joint 10, et le rebord 5, sous lequel elle se prolonge. Par contre, comme illustré sur la figure 4, le diffuseur 2 est plus court et s'arrête avant le rebord 5. Il est toutefois assez long pour reposer fermement sur le joint 10 des deux pièces d'extrémité.The end piece 3 is therefore fixed to the body 1 which engages between the inner edge 9, over the seal 10, and the flange 5, under which it extends. By cons, as illustrated in Figure 4, the diffuser 2 is shorter and stops before the flange 5. It is however long enough to rest firmly on the seal 10 of the two end pieces.

Les figures 5 et 6 sont deux vues en coupe à échelle agrandie d'une jonction entre les bords du corps 1 et du diffuseur 2 au moyen d'une agrafe 4. Plus en détail, le profil du corps 1 se prolonge par un bord qui comprend successivement un coude 15, vers l'extérieur,- une partie plane 17, portant un joint, un autre coude 26, vers l'intérieur, à partir duquel le bord se prolonge en un crochet 19 dont la partie extrême 27 est repliée vers l'extérieur. De place en place, la partie plane 17 comprend une saillie 35 en pente douce à partir du coude 17 et revenant abruptement vers la partie 17 un peu avant le coude 15.Figures 5 and 6 are two sectional views on an enlarged scale of a junction between the edges of the body 1 and the diffuser 2 by means of a clip 4. In more detail, the profile of the body 1 is extended by an edge which successively comprises an elbow 15, towards the outside, - a flat part 17, carrying a seal, another elbow 26, towards the inside, from which the edge is extended into a hook 19 whose end part 27 is folded towards outside. From place to place, the flat part 17 includes a gently sloping projection 35 from the elbow 17 and returning abruptly towards the part 17 a little before the elbow 15.

Cette partie plane, on l'a.vu , porte le joint longitudinal 18. Les saillies 35 servent à l'accrochage de l'agrafe 4.This planar part, as we have seen, carries the longitudinal seal 18. The projections 35 are used for hooking the clip 4.

De l'autre côté du joint 18, le diffuseur 2 se termine par un bord 28 constitué par une aile 29, à angle droit vers l'extérieur, prolongée par une partie courbe 30. L'aile 29 s'appuie franchement contre le joint 18. La partie courbe reçoit l'extrémité de l'agrafe 4.On the other side of the seal 18, the diffuser 2 ends with an edge 28 consisting of a wing 29, at right angles to the outside, extended by a curved portion 30. The wing 29 bears frankly against the seal 18. The curved part receives the end of clip 4.

Cette agrafe 4, ayant la forme générale d'un C est un profilé extrudé, par exemple en PVC, élastique mais résistant. Elle comprend une boucle 31 qui s'engage à l'intérieure de la partie courbe 30, une branche de raccordement 32, un montant 33 et un crochet 34.This clip 4, having the general shape of a C is a profile extruded, for example PVC, elastic but resistant. It includes a loop 31 which engages inside the curved part 30, a connecting branch 32, an upright 33 and a hook 34.

Comme on peut le voir sur la figure 5, cette agrafe prend appui à l'intérieur de la partie courbe 30 et vient s'accrocher par son extrémité 34 derrière les saillies 35, dans l'angle 15. L'élasticité du matériau dont il est fait et le dimensionnement du profilé 4 sont tels que ce profilé exerce une force pressant l'un contre l'autre les bords du corps 1 et du diffuseur 2 en pinçant uniformément le joint 18. Cela maintient le luminaire fermé et assure l'étanchéité. Le crochet 19, à l'intérieur de l'agrafe 4, s'appuie contre celle-ci par sa partie extrême 27, tandis que son jambage principal s'appuie contre la partie courbe 30.As can be seen in FIG. 5, this clip is supported inside the curved part 30 and is hooked by its end 34 behind the projections 35, in the angle 15. The elasticity of the material from which it is made and the dimensioning of the profile 4 is such that this profile exerts a force pressing one against the other the edges of the body 1 and of the diffuser 2 by uniformly pinching the joint 18. This keeps the luminaire closed and ensures the tightness . The hook 19, inside the clip 4, bears against the latter by its end portion 27, while its main leg bears against the curved portion 30.

Ces dispositions isolent le joint 18 de l'environnement extérieur, pour éviter toute accumulation de poussières sur ses parties exposées, ce qui nuirait à la longue à l'étanchéité, après que le diffuseur ait été retiré et remis en place plusieurs fois.These provisions isolate the seal 18 from the external environment, to avoid any accumulation of dust on its exposed parts, which would in the long term affect the seal, after the diffuser has been removed and replaced several times.

De plus, elles empêchent un décrochage intempestif de l'agrafe au cas où une pression serait exercée latéralement contre celle-ci de façon involontaire.In addition, they prevent an inadvertent release of the clip in the event that pressure is exerted laterally against it involuntarily.

Pour finir, la figure 6 illustre la même jonction que la figure 5, mais alors que le diffuseur a été détaché par décrochage de l'agrafe 4 du côté opposé (voir figure 2) et a basculé dans le sens des aiguilles d'une montre. On voit qu'il reste porté par l'agrafe 4 laissée en place.Finally, Figure 6 illustrates the same junction as Figure 5, but while the diffuser has been detached by unhooking the clip 4 on the opposite side (see Figure 2) and has tilted clockwise . We see that it remains carried by the clip 4 left in place.

Il est bien évident que les descriptions qui précèdent ont été données qu'à titre d'exemple non limitatif et que de nombreuses variantes peuvent être envisagées sans sortir pour autant du cadre de l'invention. En particulier, les pièces d'extrémités peuvent être associées au corps 1 par soudage ou collage, ou être des prolongements du corps 1, ce qui dispense alors de prévoir un joint d'étanchéité entre ces pièces et le corps.It is obvious that the foregoing descriptions have been given only by way of nonlimiting example and that numerous variants can be envisaged without thereby departing from the scope of the invention. In particular, the end pieces can be associated with the body 1 by welding or gluing, or be extensions of the body 1, which then dispenses with the need for a seal between these parts and the body.
