Description
La présente invention concerne une ampoule incluant un socle auquel est lié un filament, destiné à émettre un rayonnement lumineux, présentant des enroulements disposés en spirale autour d'un axe de révolution, ampoule incluant en outre une pluralité de supports, chacun présentant une extrémité liée au socle et une autre extrémité munie d'un crochet en contact avec l'un des enroulements du filament.The present invention relates to a light bulb including a base to which is bonded a filament, for emitting light radiation, having windings arranged spirally around an axis of revolution, bulb further including a plurality of supports, each having a connected end to the base and another end provided with a hook in contact with one of the windings of the filament.
Une telle ampoule est commercialisée par la demanderesse sous la référence PL10044067. Dans cette ampoule, le filament est maintenu en position au moyen d'un unique support métallique, dont une extrémité est solidaire du socle et dont une autre extrémité présente un crochet fermé entourant l'un des enroulements du filament, les deux extrémités du support étant reliées par une tige.
L'ampoule connue est configurée de sorte que, lorsque l'ampoule est dans ses conditions de fonctionnement normales, la tige du support est située au-dessous du filament. Or la demanderesse a observé que le filament, lorsqu'il est parcouru par un courant, a tendance à se déformer mécaniquement en développant une courbure déplaçant vers le bas les extrémités du filament de part et d'autre du crochet maintenant en position ledit filament.
Ainsi, plusieurs enroulements peuvent entrer en contact avec la tige du support, créant alors un court-circuit qui peut être destructeur pour le support et le filament lui-même.Such a bulb is sold by the applicant under the reference PL10044067. In this bulb, the filament is held in position by means of a single metal support, one end of which is integral with the base and whose other end has a closed hook surrounding one of the filament windings, the two ends of the support being connected by a rod.
The known bulb is configured so that when the bulb is in its normal operating condition, the support rod is located below the filament. Now the Applicant has observed that the filament, when traversed by a current, tends to deform mechanically by developing a curvature moving down the ends of the filament on either side of the hook now in position said filament.
Thus, several windings can come into contact with the support rod, creating a short circuit that can be destructive for the support and the filament itself.
EP0271858 décrit une ampoule incluant un socle auquel est lié un filament, destiné à émettre un rayonnement lumineux, présentant des enroulements disposés en spirale autour d'un axe de révolution, ampoule incluant en outre une pluralité de supports, chacun présentant une extrémité liée au socle et une autre extrémité munie d'un crochet en contact avec l'un des enroulements du filament. Les supports sont de préférence arrangés avec une distribution angulaire régulière autour du filament.EP0271858 discloses a bulb including a base to which is bonded a filament, for emitting light radiation, having windings arranged spirally about an axis of revolution, bulb further including a plurality of supports, each having an end connected to the base and another end provided with a hook in contact with one of the filament windings. The supports are preferably arranged with a regular angular distribution around the filament.
La présente invention a pour but de prévenir tout risque de court-circuit lié à une déformation du filament, en proposant une ampoule dans laquelle l'ampleur de la déformation du filament est limitée.The present invention aims to prevent any risk of short circuit related to deformation of the filament, by proposing a bulb in which the extent of deformation of the filament is limited.
En effet, selon l'invention, une ampoule conforme au paragraphe introductif est caractérisée en ce que les crochets sont tous situés d'un même côté de l'axe de révolution du filament. La multiplicité des supports prévue par l'invention permet un meilleur maintien en position du filament et empêche la mise en contact simultanée de plusieurs de ses enroulements avec un même support.Indeed, according to the invention, a bulb according to the introductory paragraph is characterized in that the hooks are all located on the same side of the axis of revolution of the filament. The multiplicity of supports provided by the invention allows a better hold in position of the filament and prevents the simultaneous contact of several of its windings with the same support.
Un tel mode de réalisation simplifie la fabrication des supports, qui peuvent être ainsi constitués par une unique tige munie d'une pluralité de crochets. La réalisation de la liaison entre les supports et le socle s'en trouvera également simplifiée.Such an embodiment simplifies the manufacture of the supports, which can thus be constituted by a single rod provided with a plurality of hooks. The realization of the connection between the supports and the base will also be simplified.
Dans un mode de réalisation particulier de l'ampoule conforme à invention, les supports sont destinés à être situés au-dessus du filament lorsque l'ampoule se trouve dans ses conditions normales de fonctionnement, les crochets des supports sont des crochets ouverts.In a particular embodiment of the lamp according to the invention, the supports are intended to be located above the filament when the bulb is in its normal operating conditions, the brackets of the supports are open hooks.
Le fait que les crochets soient ouverts simplifie considérablement la fabrication de l'ampoule. En effet, lorsque les crochets sont fermés, le filament doit être en quelque sorte vissé dans les ouvertures des crochets, ce qui prend un temps non-négligeable qui se répercute sur les coûts de fabrication de l'ampoule. L'utilisation de crochets ouverts nécessite simplement de poser les enroulements sur les crochets et diminue donc les coûts de fabrication de l'ampouleThe fact that the hooks are open greatly simplifies the manufacture of the bulb. Indeed, when the hooks are closed, the filament must be somehow screwed into the openings of the hooks, which takes a non-negligible time which has repercussions on the manufacturing costs of the bulb. The use of open hooks simply requires to put the windings on the hooks and thus reduces the manufacturing costs of the bulb
Dans un mode de réalisation préféré de invention, une extrémité du filament étant solidaire du socle, l'autre extrémité du filament est reliée audit socle via une armature formée par une tige située en dehors d'un plan défini par l'axe de révolution et des points de contact entre les crochets et le filament.In a preferred embodiment of the invention, one end of the filament being secured to the base, the other end of the filament is connected to said base via an armature formed by a rod located outside a plane defined by the axis of revolution and points of contact between the hooks and the filament.
Ce mode de réalisation de l'armature permet d'assurer que celle-ci se trouve en-dehors d'une trajectoire que suivraient, sous l'effet de la déformation mécanique observée pour l'ampoule connue, les enroulements du filament si ceux-ci n'étaient maintenus en position. Un tel choix prévient donc tout risque de court-circuit entre le filament et l'armature.This embodiment of the armature ensures that it is outside a path that would follow, under the effect of the mechanical deformation observed for the known bulb, the windings of the filament if they they were kept in position. Such a choice prevents any risk of short circuit between the filament and the frame.
L'invention sera mieux comprise à l'aide de la description suivante, faite à titre d'exemple non-limitatif et en regard des dessins annexés, dans lesquels :
- la figure 1 est un schéma décrivant une ampoule connue, et
- figure 2 est un schéma décrivant une ampoule conforme à un mode de réalisation préféré de l'invention.
- FIG. 1 is a diagram describing a known bulb, and
- Figure 2 is a diagram describing a bulb according to a preferred embodiment of the invention.
La figure 1 représente schématiquement une ampoule connue dans une configuration correspondant à ses conditions normales de fonctionnement. Cette ampoule comporte une fiche SO et un tube TUB réalisé en un matériau transparent, par exemple du verre. Ce tube enferme un filament FIL, destiné à émettre un rayonnement lumineux, présentant des enroulements disposés en spirale autour d'un axe de révolution AX. L'une des extrémités de ce filament FIL est liée à un socle BA, l'autre extrémité étant reliée audit socle via une armature ARM, matérialisée par une tige métallique disposée au-dessus du filament FIL. Le filament FIL et l'armature ARM forment ainsi un circuit de courant relié à la fiche SO. Dans l'ampoule connue, le filament FIL est maintenu en position au moyen d'un unique support métallique SUP, dont une extrémité est solidaire du socle BA et dont une autre extrémité présente un crochet fermé CH entourant l'un des enroulements du filament FIL, les deux extrémités du support SUP étant reliées par une tige disposée au-dessous du filament FIL. La demanderesse a observé que le filament FIL, lorsqu'il est parcouru par un courant, a tendance à se déformer mécaniquement en développant une courbure déplaçant vers le bas les extrémités du filament FIL de part et d'autre du crochet maintenant en position ledit filament. Ainsi, plusieurs enroulements peuvent entrer en contact avec la tige du support SUP, créant alors un court-circuit qui peut être destructeur pour le support SUP et le filament FIL lui-même.Figure 1 shows schematically a known bulb in a configuration corresponding to its normal operating conditions. This bulb has an SO plug and a TUB tube made of a transparent material, for example glass. This tube encloses a filament FIL, intended to emit light radiation, having windings arranged in a spiral around an axis of revolution AX. One of the ends of this filament FIL is linked to a base BA, the other end being connected to said base via an armature ARM, materialized by a metal rod disposed above the filament FIL. The filament wire and the armature ARM thus form a current circuit connected to the plug SO. In the known bulb, the filament FIL is held in position by means of a single metal support SUP, one end of which is integral with the base BA and of which another end has a closed hook CH surrounding one of the windings of the filament FIL. , the two ends of the support SUP being connected by a rod disposed below the filament FIL. Applicant has observed that the filament FIL, when traversed by a current, tends to deform mechanically by developing a curvature moving down the ends of the filament FIL on either side of the hook maintaining in position said filament . Thus, several windings can come into contact with the SUP support rod, creating a short circuit which can be destructive for the SUP carrier and the FIL filament itself.
La figure 2 représente schématiquement une ampoule conforme à un mode de réalisation préféré de l'invention, dans une configuration correspondant à ses conditions normales de fonctionnement. Les éléments communs à l'ampoule connue y sont munis de références identiques. Dans ce mode de réalisation de l'invention, le filament FIL est maintenu en position au moyen de trois crochets H1, H2, H3, reliés au socle BA via une tige.
L'invention permet un meilleur maintien en position du filament FIL et empêche celui-ci de se déformer vers le bas autour du crochet médian H2. Dans ce mode de réalisation particulier de l'invention, les crochets H1, H2, H3 sont tous situés au-dessus du filament FIL, ce qui permet de n'utiliser qu'une seule tige pour relier lesdits crochets au socle BA, et diminue encore les risques de court-circuit liés à une éventuelle déformation du filament FIL, une telle déformation se faisant vers le bas.
Par ailleurs, les crochets H1, H2 et H3 sont ici des crochets ouverts, ce qui simplifie considérablement la fabrication de l'ampoule, puisque le filament pourra être posé sur lesdits crochets alors qu'il devrait être vissé dans des crochets fermés.
Enfin, dans ce mode de réalisation de l'invention, l'armature ARM est constituée par une tige située en dehors d'un plan défini par l'axe de révolution AX et des points de contact entre les crochets H1, H2, H3 et le filament FIL. Une éventuelle déformation du filament FIL ne pouvant en principe se produire que dans le plan défini par l'axe de révolution AX et lesdits points de contact, le positionnement particulier de l'armature ARM élimine tout risque de contact entre ladite armature et des enroulements du filament FIL.FIG. 2 schematically represents an ampoule according to a preferred embodiment of the invention, in a configuration corresponding to its conditions normal operation. The elements common to the known bulb are provided with identical references. In this embodiment of the invention, the filament FIL is held in position by means of three hooks H1, H2, H3 connected to the base BA via a rod.
The invention allows a better hold in position of the filament FIL and prevents it from deforming downwards around the median hook H2. In this particular embodiment of the invention, the hooks H1, H2, H3 are all located above the filament FIL, which makes it possible to use only one rod to connect said hooks to the base BA, and decreases again the risks of short circuit related to a possible deformation of the FIL filament, such deformation being down.
Furthermore, the hooks H1, H2 and H3 are here open hooks, which greatly simplifies the manufacture of the bulb, since the filament may be placed on said hooks while it should be screwed into closed hooks.
Finally, in this embodiment of the invention, the armature ARM is constituted by a rod located outside a plane defined by the axis of revolution AX and contact points between the hooks H1, H2, H3 and filament FIL. As a possible deformation of the filament FIL can in principle only occur in the plane defined by the axis of revolution AX and said contact points, the particular positioning of the armature ARM eliminates any risk of contact between said armature and windings of the filament FIL.
