Description

L'invention concerne un appareil d'éclairage à tubes fluorescents.The invention relates to a fluorescent tube lighting fixture.

Dans les locaux où règne une ambiance humide, corrosive, ou fortement empoussiérée, il est connu de prévoir des appareils étanches d'éclairage à tubes fluorescents. Ces appareils comportent en général deux éléments principaux en cuvette : le corps et la vasque. Ces deux éléments sont en matière plastique injectée, la vasque étant translucide, Ils ont des dimensions bien définies : chaque modèle d'appareil d'éclairage correspondant à deux moules.In premises where a humid, corrosive or highly dusty atmosphere prevails, it is known to provide watertight lighting fixtures with fluorescent tubes. These devices generally have two main elements in the bowl: the body and the bowl. These two elements are made of injected plastic, the bowl being translucent. They have well-defined dimensions: each model of lighting fixture corresponding to two molds.

Le corps et la vasque sont mis en place en regard l'un de l'autre avec interposition d'un joint annulaire d'étanchéité. Pour assurer leur assemblage, on dispose des crochets de verrouillage qui sont mis en place au moment de l'installation de l'appareil d'éclairage.The body and the basin are placed facing each other with the interposition of an annular seal. To ensure their assembly, there are locking hooks which are put in place when installing the lighting fixture.

L'un des buts de l'invention est de proposer un appareil d'éclairage de construction simple et d'assemblage aisé, ne faisant pas appel à des crochets de verrouillage.One of the objects of the invention is to propose a lighting apparatus of simple construction and easy assembly, not requiring the use of locking hooks.

Un autre but de l'invention est de prévoir un appareil étanche d'éclairage dont la longueur puisse être déterminée sans être tributaire des dimensions de moules.Another object of the invention is to provide a waterproof lighting device the length of which can be determined without being dependent on the dimensions of the molds.

Un autre but encore de l'invention est de proposer, pour cet appareil d'éclairage, un mode de fixation particulièrement pratique et de réglage facile. L'invention a pour objet un appareil étanche d'éclairage à tubes fluorescents, du type comportant un corps en matière plastique et une vasque transparente, à l'intérieur desquels est disposée la réglette ou unité électrique, caractérisé en ce que le corps et la vasque sont des profilés extrudés tronçonnés à la longueur voulue et fixés l'un à l'autre par encliquetage.Yet another object of the invention is to propose, for this lighting apparatus, a particularly practical method of attachment and easy adjustment. The subject of the invention is a waterproof lighting device with fluorescent tubes, of the type comprising a plastic body and a transparent bowl, inside of which is the strip or electrical unit, characterized in that the body and the washbasin are extruded sections cut to the desired length and fixed to one another by snap-fastening.

Selon d'autres caractériques de l'invention :

  • - deux embouts en matériau thermoplastique injecté sont encliquetés sur le corps,
  • - chacun des embouts porte un joint annulaire qui s'applique à l'intérieur du corps et de la vasque pour assurer l'étanchéité transversale,
  • - entre le corps et la vasque est disposé un joint linéaire sur lequel, en raison de l'encliquetage de la vasque sur le corps, la pression d'appui est constante,
  • - le corps et la vasque sont en forme de canal, avec un fond plat et deux flancs inclinés,
  • - chaque flanc du corps porte un bord à deux concavités inversées, la première concavité étant tournée vers l'intérieur du corps et destinée à recevoir le joint linéaire d'étanchéité,
  • - la deuxième concavité est tournée vers l'extérieur et destinée à recevoir une nervure d'accrochage de la vasque,
  • - chaque flanc de la vasque est prolongé par un bord intérieur qui s'applique sur le joint d'étanchéité et par une bordure extérieure portant la nervure d'encliquetage de la vasque sur le corps,
  • - le corps porte des nervures longitudinales susceptibles de coopérer avec des crochets d'une embase pour fixer l'appareil par encliquetage.
  • le corps est alvéolaire.
According to other features of the invention:
  • - two end caps in injected thermoplastic material are snapped onto the body,
  • - each end piece has an annular seal which is applied inside the body and the bowl to ensure transverse sealing,
  • - between the body and the basin is arranged a linear joint on which, due to the latching of the basin on the body, the contact pressure is constant,
  • - the body and the basin are channel-shaped, with a flat bottom and two inclined sides,
  • each side of the body carries an edge with two inverted concavities, the first concavity being turned towards the interior of the body and intended to receive the linear seal,
  • - the second concavity is turned towards the outside and intended to receive a catching rib of the basin,
  • - each side of the basin is extended by an internal edge which is applied to the seal and by an external border carrying the ratchet rib of the basin on the body,
  • - The body carries longitudinal ribs capable of cooperating with hooks of a base to fix the device by snap-fastening.

A titre d'exemple, on a représenté au dessin annexé :

  • Figure 1 : une vue perspective d'un appareil d'éclairage selon l'invention utilisé en plafonnier ;
  • Figure 2 : une vue en coupe perpendiculaire à l'axe longitudinal de l'appareil d'éclairage de la figure 1, sans la réglette, ou unité électrique, et sans l'embout;
  • Figure 3 : une vue, de l'intérieur d'un embout de l'appareil d'éclairage de la figure 1 ;
  • Figure 4 : une vue en coupe selon la figure 2 de l'appareil complet.
By way of example, the accompanying drawing shows:
  • Figure 1: a perspective view of a lighting device according to the invention used in ceiling lights;
  • Figure 2: a sectional view perpendicular to the longitudinal axis of the lighting apparatus of Figure 1, without the strip, or electrical unit, and without the nozzle;
  • Figure 3: a view of the interior of a tip of the lighting apparatus of Figure 1;
  • Figure 4: a sectional view according to Figure 2 of the complete apparatus.

Es se reportant à la figure 1, on voit que l'appareil étanche d'éclairage selon l'invention se compose essentiellement d'un corps 1, de deux embouts 2, 3 et d'une vasque 4.With reference to FIG. 1, it can be seen that the waterproof lighting device according to the invention essentially consists of a body 1, two end pieces 2, 3 and a basin 4.

Le corps 1 est en matériau plastique alvéolaire. Il se présente sous forme de profilé extrudé qui est ensuite tronçonné à la longueur voulue pour chaque appareil d'éclairage. Sur la figure 2, on voit que le corps 1 est muni d'alvéoles longitudinales 5 ayant pour rôle de l'alléger tout en lui conservant une certaine rigidité. A la partie supérieure, le corps 1 porte deux nervures longitudinales 6 et 7 coudées, susceptibles de coopérer avec des crochets 8, 9 d'une embase de fixation 10. Les crochets 8, 9 sont portés par des bras souples de façon à permettre une suspension du corps 1 par simple encliquetage.The body 1 is made of cellular plastic material. It is in the form of an extruded profile which is then cut to the desired length for each lighting device. In Figure 2, we see that the body 1 is provided with longitudinal cells 5 having the role of lightening it while retaining a certain rigidity. At the upper part, the body 1 carries two longitudinal ribs 6 and 7 bent, capable of cooperating with hooks 8, 9 of a fixing base 10. The hooks 8, 9 are carried by flexible arms so as to allow suspension of the body 1 by simple click.

Le corps 1 se présente comme un canal à fond plat 11 avec deux flancs inclinés 12 et 13. Chaque flanc est limité par un bord 14, 15 dont la section présente deux concavités inversées. La première concavité est tournée vers l'intérieur du corps 1. Elle est destinée à recevoir un joint d'étanchéité 16, linéaire. La deuxième concavité est tournée vers l'extérieur, elle est destinée à recevoir une nervure d'accrochage 17 de la vasque 4.The body 1 is presented as a flat-bottom channel 11 with two inclined flanks 12 and 13. Each flank is limited by an edge 14, 15 whose section has two inverted concavities. The first concavity is turned towards the inside of the body 1. It is intended to receive a seal 16, linear. The second concavity faces outwards, it is intended to receive a hooking rib 17 of the basin 4.

La vasque 4 est en profilé extrudé, avec sensiblement la même forme générale que le corps 1. Comme elle doit être transparente, elle est en polystyrène par exemple, ou en polycarbonate afin d'améliorer sa résistance aux chocs éventuels. Pour mieux maîtriser la répartition du flux lumineux émis par les tubes fluorescents disposés dans l'appareil d'éclairage, elle est à structure prismatique.The basin 4 is in extruded profile, with substantially the same general shape as the body 1. As it must be transparent, it is made of polystyrene for example, or of polycarbonate in order to improve its resistance to possible shocks. To better control the distribution of the light flux emitted by the fluorescent tubes placed in the lighting fixture, it has a prismatic structure.

Elle se présente comme un canal à fond plat 18, avec deux flancs inclinés 19, 20. Chaque flanc est prolongé par un bord intérieur 21 et une bordure extérieure 22, parallèles entre eux. Le bord intérieur est une paroi qui s'appuie sur le joint d'étanchéité 16, de façon à assurer l'étanchéité longitudinale de l'appareil entre le corps 1 et la vasque 4. La bordure extérieure 22 porte, dans sa partie inférieure, la nervure d'accrochage 17 susceptible de s'encliqueter dans la deuxième concavité, tournée vers l'extérieur, du bord 14 du corps 1. Elle porte également, au voisinage de son extrémité supérieure, une deuxième nervure 23 susceptible de s'encliqueter sur le bord supérieur de la première concavité, tournée vers l'intérieur, du bord 14 du corps 1. L'extrémité supérieure 24 de la bordure extérieure 22 est saillante vers le haut, de façon à permettre une préhension pour dégager les deux nervures 23 et 17 du bord 14 du corps 1 lorsqu'on doit enlever la vasque 4 pour remplacer les tubes fluorescents par exemple.It appears as a flat bottom channel 18, with two inclined sides 19, 20. Each side is extended by an inner edge 21 and an outer edge 22, parallel to each other. The inner edge is a wall which rests on the seal 16, so as to ensure the longitudinal tightness of the device between the body 1 and the bowl 4. The outer edge 22 carries, in its lower part, the hooking rib 17 capable of snapping into the second concavity, facing outwards, from the edge 14 of the body 1. It also carries, in the vicinity of its upper end, a second rib 23 capable of snapping onto the upper edge of the first concavity, turned inwards, from the edge 14 of the body 1. The upper end 24 of the outer edge 22 projects upwards, so as to allow a grip to release the two ribs 23 and 17 of the edge 14 of the body 1 when the bowl 4 has to be removed to replace the fluorescent tubes for example.

Sur la figure 3, on voit la face intérieure de l'embout 3 de la figure 1. Cet embout 3 est en matériau thermoplastique injecté. Sa forme extérieure est définie pour son adaptation d'une part au corps 1, d'autre part à la vasque 4. La face d'extrémité 25 est munie d'un presse-étoupe 26 pour le passage du câble d'alimentation. La surface latérale 27 entoure le coups 1, c'est pourquoi elle présente deux fentes 28, 29, pour laisser passer les nervures longitudinales 6, 7. L'embout 3 présente une paroi intérieure 30 maintenue de l'intérieur par des nervures radiales 31 partielles. Cette paroi 30 sert d'appui et de support à un joint annulaire 32. Ainsi qu'on peut le voir sur la figure 4, ce joint 32 s'applique à l'intérieur du corps 1, qui se trouve tenu entre d'une part la surface latérale 27 à l'extérieur et d'autre part le joint 32 à l'intérieur. De même, le joint 32 s'applique sur l'intérieur de la vasque 4.In Figure 3, we see the inner face of the tip 3 of Figure 1. This tip 3 is made of injected thermoplastic material. Its external shape is defined for its adaptation on the one hand to the body 1, on the other hand to the basin 4. The end face 25 is provided with a cable gland 26 for the passage of the power cable. The lateral surface 27 surrounds the blows 1, this is why it has two slots 28, 29, to let the longitudinal ribs 6, 7. The end piece 3 has an inner wall 30 held from the inside by radial ribs 31 partial. This wall 30 serves as a support and support for an annular seal 32. As can be seen in FIG. 4, this seal 32 applies to the interior of the body 1, which is held between a the side surface 27 on the outside and the seal 32 on the inside. Likewise, the seal 32 is applied to the interior of the basin 4.

Sur la figure 4, on voit que la réglette, ou unité électrique 33 est en place dans l'appareil. Elle est fixée aux supports en L représentés en 36 et 37 sur la figure 2, par des moyens non décrits pour ne pas surcharger le dessin. Dans cet exemple de réalisation, deux tubes fluorescents 34 et 35 ont été représentés.In Figure 4, we see that the strip, or electrical unit 33 is in place in the device. It is fixed to the L-shaped supports shown at 36 and 37 in FIG. 2, by means not described so as not to overload the drawing. In this exemplary embodiment, two fluorescent tubes 34 and 35 have been shown.

L'appareil d'éclairage selon l'invention est réalisé de manière particulièrement simple et économique. Tout d'abord en fonction de la puissance électrique désirée, c'est-à-dire de la longueur des tubes fluorescents, on détermine la longueur du corps 1 et celle de la vasque 4, et on prélève les tronçons de profilés correspondants. On met en place le corps 1, les embouts 2, 3 et la réglette 33. On fixe le corps 1 et les embouts 2, 3 par encliquetage. On met en place les tubes 34, 35 et on fixe la vasque par encliquetage. L'ensemble de l'appareil est alors prêt à être fixé sur une embase 10, par encliquetage des nervures 6, 7 sur les crochets 8, 9. Une ou plusieurs embases étant fixées au plafond, on y accroche l'appareil d'éclairage par encliquetage. Ensuite on fait le réglage en position de l'appareil par coulissement axial par rapport aux embases. Enfin on assure le blocage en position de l'appareil au moyen par exemple d'une pièce de verrouillage coulissante prévue dans chaque embase.The lighting device according to the invention is produced in a particularly simple and economical manner. First of all as a function of the desired electrical power, that is to say of the length of the fluorescent tubes, the length of the body 1 and that of the basin 4 are determined, and the sections of corresponding profiles are removed. The body 1, the end pieces 2, 3 and the strip 33 are put in place. The body 1 and the end pieces 2, 3 are fixed by snap-fastening. The tubes 34, 35 are put in place and the basin is fixed by snap-fastening. The whole apparatus is then ready to be fixed on a base 10, by snapping on the ribs 6, 7 on the hooks 8, 9. One or more bases being fixed to the ceiling, the lighting fixture is hung there. by snap-fastening. Then the device is adjusted in position by axial sliding relative to the bases. Finally we ensure the blocking position of the device by means, for example, of a sliding locking part provided in each base.

Dans l'appareil électrique selon l'invention, l'étanchéité transversale est assurée par les deux joints annulaires 32 des embouts, et l'étanchéité longitudinale par les joint linéaires 16. Comme la pression d'appui sur ces joints est constante, l'étanchéité est assurée dans les meilleures conditions.In the electrical device according to the invention, the transverse seal is ensured by the two annular seals 32 of the end pieces, and the longitudinal seal by the linear seals 16. As the bearing pressure on these seals is constant, the sealing is ensured under the best conditions.

L'appareil d'éclairage selon l'invention peut également être prévu sans étanchéité, avec une vasque posée, sans appui sur un joint d'étanchéité et sans encliquetage.The lighting device according to the invention can also be provided without sealing, with a basin installed, without pressing on a seal and without snap-fastening.
