Description

Dans le brevet français 2 317 591, on a décrit un appareil d'éclairage pour lampes fluorescentes du type réglette comprenant une semelle en tôle supportant des accessoires de lampe tels que démarreur, self de ballast et au moins une paire de supports de socle fixés aux deux extrémités de la semelle. La semelle est recouverte par un capot retenu dans les deux supports de socle en matière isolante et écarté de la semelle par des bourrelets distanciers dans ces supports de socles.In French patent 2 317 591, a lighting device for fluorescent lamps of the strip type has been described comprising a sheet metal sole supporting lamp accessories such as a starter, ballast choke and at least one pair of base supports fixed to the two ends of the sole. The sole is covered by a cover retained in the two base supports made of insulating material and separated from the sole by distance beads in these base supports.

Dans ces appareils d'éclairage connus, des bruits peuvent apparaître lorsque la self de ballast présente un flux de dispersion au delà d'un certain seuil. D'autre part, le fait que le capot est complètement isolé de la semelle peut être une source de danger en cas d'un défaut d' isolation du câblage qui met sous tension le capot.In these known lighting fixtures, noises can appear when the ballast choke has a dispersion flux beyond a certain threshold. On the other hand, the fact that the cover is completely isolated from the sole can be a source of danger in the event of a fault in the insulation of the wiring which energizes the cover.

L'invention a pout but d'éviter ces inconvénients. Elle est caractérisée en ce qu'au moins un élément distancier élastique est inséré dans la fente entre la semelle et le capota au moins à proximité immédiate de la self de ballast. L'élément distancier élastique est de préférence en métal, afin d'assurer en même temps le contact électrique entre capot et semelle.The invention aims to avoid these drawbacks. It is characterized in that at least one elastic distance element is inserted in the slot between the sole and the hood at least in the immediate vicinity of the ballast choke. The elastic distance element is preferably made of metal, in order to ensure at the same time the electrical contact between cover and sole.

L'invention est expliquée ci-dessous par rapport a deux variantes représentées aux figures 1 et 2. La figure 1 est une vue en perspective partiellement coupée; la figure 2 est une coupe transversale à travers un appareil d'éclairage du type réglette, non équipé de lampe.The invention is explained below with respect to two variants shown in Figures 1 and 2. Figure 1 is a partially cut perspective view; Figure 2 is a cross section through a light fixture of the strip type, not equipped with lamp.

A la figure 1, un appareil d'éclairage pour lampes fluorescentes est composé d'une semelle 1, d'un capot 2 et de deux supports 3 de socle 4. Le support 3 comprend une plaque de base 5 sur laquelle repose la semelle 1. Dans la plaque de base 5 est ménagé au moins une ouverture 6 permettant de verrouiller la semelle 1 dès qu'elle est enfichée à fond dans le support 3 de socle 4.In FIG. 1, a lighting device for fluorescent lamps is composed of a sole 1, a cover 2 and two supports 3 for a base 4. The support 3 comprises a base plate 5 on which the sole 1 rests In the base plate 5 there is provided at least one opening 6 making it possible to lock the sole 1 as soon as it is fully inserted in the support 3 of the base 4.

La moitié gauche supérieure du support 3 de socle 4 est montrée vide, et pour plus de clareté, une partie de la semelle 1 est enlevée pour laisser apparaître la conformation de l'intérieur du support 3. On voit ainsi notamment, en entier un bourrelet 7 séparant les arêtes de la semelle 1 de celles du capot 2The upper left half of the support 3 of the base 4 is shown empty, and for more clarity, a part of the sole 1 is removed to reveal the conformation of the interior of the support 3. We thus see in particular a whole bead 7 separating the edges of the sole 1 from those of the cover 2

La semelle 1 peut supporter, comme cela est en soi bien connu, des dispositifs auxiliaires pour lampes fluorescentes tels que démarreur condensateur, self de ballast etc., non représentés.The sole 1 can support, as is well known per se, auxiliary devices for fluorescent lamps such as a starter capacitor, ballast choke etc., not shown.

Lorsqu'une self de ballast présente un flux de dispersion d'une certaine importance, et si, comme c'est génératlement le cas, la semelle 1 et le capot2 sont en acier, ces deux éléments peuvent commencer à vibrer et faire du bruit. Pour éviter cela, un élément distancier élastique,en l'occurrence une boucle 8 d'un bracelet 9 en acier, est inséré dans la fente entre la semelle et le capot. Le bracelet 9 est de préférence placé à l'endroit où est fixée la self de ballast, par exemple au milieu de la self; ou deux bracelets 9 sont placés aux deux extrémités de la self, non représentée.When a ballast choke has a dispersion flux of some importance, and if, as is generally the case, the sole 1 and the cover 2 are made of steel, these two elements can start to vibrate and make noise. To avoid this, an elastic distance element, in this case a loop 8 of a steel bracelet 9, is inserted in the slot between the sole and the cover. The bracelet 9 is preferably placed at the place where the ballast choke is fixed, for example in the middle of the choke; or two bracelets 9 are placed at the two ends of the self, not shown.

Le fait d'utiliser un distancier élastique en métal conducteur d' électricité permet de connecter le capot 2 au potentiel de la semelle et d'éviter qu'en cas de défaut d'isolement, le capot puisse se trouver sous tension et provoquer un accident lorsqu'une personne est amenée à le toucher.The fact of using an elastic distance meter made of electrically conductive metal makes it possible to connect the cover 2 to the potential of the sole and to avoid that in the event of an insulation fault, the cover may be energized and cause an accident. when a person is touched.

Une variante de l'invention est montrée à la figure 2. Le distancier élastique se présente ici sous forme de boucles 10 aux extrémités d'un étrier 11 également en un ruban métallique, maintenu par la self de ballast 12. Cette variante permet d'atteindre une mise à la terre sûre du capot 2 via le boîtier de la self de ballast 12 même si le capot 2 et le boîtier de la self 12 sont recouverts de couches de peinture. Pour ce faire, la boucle 10 est conformée de manière à ce que l'arête coupée de la tôle constituant le capot 2 appuie dans une direction approximativement perpendiculaire sur une partie de la boucle 10 de manière que la tôle nue qui apparaît sur cette arête entre en contact franc avec la boucle 10. De plus, les branches latérales de l'étrier Il présentent des nervures ou parties bombées 13 dont les bords acérés 14 sont appliqués sur le boîtier de la self 12 et percent en le griffant un revêtement de peinture de ce boîtier pour assurer un bon contact électrique. Les parties bombées 13 servent à écarter du boîtier de la self 12 les fils d'alimentation 15 de l'appareil pour éviter leur échauffement au contact avec le boîtier de la self de ballast.A variant of the invention is shown in FIG. 2. The elastic distance device is here presented in the form of loops 10 at the ends of a stirrup 11 also in a metallic strip, held by the ballast choke 12. This variant makes it possible to achieve safe earthing of the cover 2 via the housing of the ballast choke 12 even if the cover 2 and the housing of the choke 12 are covered with layers of paint. To do this, the loop 10 is shaped so that the cut edge of the sheet forming the cover 2 presses in a direction approximately perpendicular to part of the loop 10 so that the bare sheet which appears on this edge between in frank contact with the loop 10. In addition, the lateral branches of the stirrup II have ribs or convex parts 13 whose sharp edges 14 are applied to the housing of the inductor 12 and pierce by scratching a coating of paint of this box to ensure good electrical contact. The convex parts 13 serve to separate the supply wires 15 of the apparatus from the housing of the inductor 12 to prevent them from heating up in contact with the housing of the ballast inductor.

Le bracelet 9 (fig.1) peut comprendre des boucles 16 et 17 dans lesquelles sont maintenues les fils d'alimentation 15. Ces boucles 16 et 17 peuvent être disposées notamment aux endroits voisins du sommet du capot 2, comme montré à la figure 1. En vue des exigences d'isolation double, le bracelet 9 peut être gainé, au moins à l'endroit des boucles.The bracelet 9 (fig. 1) can include loops 16 and 17 in which the supply wires 15 are kept. These loops 16 and 17 can be arranged in particular at places close to the top of the cover 2, as shown in FIG. 1 In view of the double insulation requirements, the bracelet 9 can be sheathed, at least at the location of the loops.
