Abstract

The lamp standard fitting includes a reflector body (10) housing the reflector itself (30). At the end of the body distant from the post (90) on which the fitting is mounted is the movable socket carrier (40), the metal fitting (70) of the bulb being mounted in this carrier. Electrical connections are provided for this socket carrier, and consist of a first fixed connector and a second connector dependant on the socket carrier. Connection between the connectors is ensured by the movement of the socket carrier into or out of position within the reflector body. The connector is able to provide three supply contacts, for phase, neutral and the high tension output of a starter circuit. <IMAGE>

Description

La présente invention concerne un luminaire, notamment pour l'éclairage public ou industriel, comportant un corps de réflecteur et un dispositif porte-douille destiné à recevoir une source lumineuse amovible par rapport au corps de réflecteur.The present invention relates to a luminaire, in particular for public or industrial lighting, comprising a reflector body and a device socket holder intended to receive a light source removable from the reflector body.

Les luminaires utilisés dans le domaine de l'éclairage public ou industriel doivent de nos jours répondre à une double exigence, qui est d'une part de fournir une distribution lumineuse parfaitement contrôlée et d'autre part de permettre une installation et une maintenance sur site simplifiées.Luminaires used in the field of public lighting or nowadays industrialists have to meet a double requirement, which is on the one hand to provide a perfectly controlled light distribution and on the other hand allow simplified installation and maintenance on site.

Les progrès dans la géométrie des réflecteurs, grâce notamment à la conception assistée par ordinateur, ont permis de répondre à cette première exigence, en apportant un plus grand confort visuel et une meilleure utilisation de l'énergie. Toutefois, un positionnement bien précis de la source lumineuse vis-à-vis de son réflecteur est alors nécessaire, ce qui impose souvent de placer la douille dans une partie difficilement accessible du luminaire. Par ailleurs, la grande précision requise pour le positionnement de la source nécessite un montage mécanique de la douille sur un dispositif de support qui assure une bonne tenue mécanique et qui est spécifiquement adapté au type de réflecteur auquel il est associé.Advances in the geometry of reflectors, thanks in particular to the computer-aided design, made it possible to respond to this first requirement, by providing greater visual comfort and better use of energy. However, a very precise positioning of the light source vis-à-vis of its reflector is then necessary, which often requires placing the socket in a difficult-to-access part of the luminaire. Furthermore, the great precision required for positioning the source requires mounting sleeve mechanics on a support device which ensures a good hold mechanical and which is specifically adapted to the type of reflector for which it is associated.

Or, ce type de montage tend à compliquer les interventions sur site, notamment lorsqu'il s'agit de changer la source lumineuse ou de réparer des contacts électriques au niveau de la douille.However, this type of assembly tends to complicate interventions on site, especially when it comes to changing the light source or repairing electrical contacts at the socket.

Ce problème peut être en partie résolu par l'emploi d'un dispositif porte-douille amovible qui permet alors de dégager la douille avec sa source lumineuse hors de l'espace confiné à l'intérieur du réflecteur.This problem can be partly solved by using a device removable socket holder which then releases the socket with its source outside the confined space inside the reflector.

A titre d'exemple, un luminaire ayant un dispositif porte-douille amovible a déjà été proposé dans le document FR-A-2 621 682.For example, a luminaire having a socket holder device removable has already been proposed in document FR-A-2 621 682.

Ce luminaire comporte un compartiment réflecteur, contenant un dispositif porte-douille et des éléments de circuit électrique, l'ensemble étant fermé par un capot amovible. Le branchement du dispositif porte-douille à l'alimentation électrique s'opère par un bloc connecteur physiquement séparé du dispositif porte-douille, et raccordé à celui-ci par un faisceau de fils.This luminaire has a reflector compartment, containing a socket holder and electrical circuit elements, the assembly being closed by a removable cover. The connection of the socket holder device to power is supplied by a connector block physically separate from the socket holder device, and connected thereto by a bundle of wires.

Lorsqu'il est nécessaire de retirer le dispositif porte-douille du compartiment réflecteur, par exemple pour changer la source lumineuse ou pour nettoyer les contacts électriques, il faut avant tout procéder à sa déconnexion, non seulement pour des raisons de sécurité, mais aussi pour éviter d'endommager les circuits d'alimentation. Pour cette raison, le luminaire comporte un interrupteur agencé pour fonctionner automatiquement lors du retrait du capot.When it is necessary to remove the socket holder from the reflective compartment, for example to change the light source or to clean the electrical contacts, it must first be disconnected, not only for safety reasons, but also to avoid damaging the supply circuits. For this reason, the luminaire has a switch arranged to operate automatically when the cover is removed.

Cependant, il existe un risque de fermeture intempestive de l'interrupteur par un élément étranger, tel qu'un outil, déposé accidentellement sur l'interrupteur durant une intervention. Ce risque est d'autant plus grave que les sources lumineuses dans ce type de luminaire sont alimentées par des cycles d'amorçage de haute tension, de l'ordre de quelques kilovolts, qui sont présents à chaque allumage, et notamment durant le changement de la source lumineuse.However, there is a risk of inadvertent closure of the switch by a foreign element, such as a tool, accidentally deposited on the switch during an intervention. This risk is all the more serious as the light sources in this type of luminaire are powered by cycles high voltage ignition, of the order of a few kilovolts, which are present at each ignition, and especially during the change of the light source.

Par ailleurs, la séparation entre le dispositif porte-douille de son ensemble connexion électrique tend à compliquer l'assemblage du luminaire et exige qu'un minimum d'accessibilité soit prévu à cet effet, ce qui nuit à la compacité de l'ensemble.Furthermore, the separation between the socket holder device of its electrical connection assembly tends to complicate the assembly of the luminaire and requires a minimum of accessibility to this effect, which affects the compactness of the whole.

Pour un exemple de luminaire correspondant sensiblement au préambule de la revendication 1, référence peut être faite au document FR-A-1 450 136.For an example of a luminaire corresponding substantially to the preamble of claim 1, reference may be made to document FR-A-1 450 136.

Ainsi, un objet de la présente invention est de remédier à ces inconvénients en proposant un luminaire destiné à l'éclairage public ou industriel comprenant un corps de réflecteur, un dispositif porte-douille amovible, une douille montée sur le dispositif porte-douille, des moyens de fixation mécanique du dispositif porte-douille sur le corps de réflecteur, permettant le montage et le démontage du dispositif porte-douille, et des moyens de raccordement électrique du dispositif porte-douille, comprenant un connecteur fixe sur le corps de réflecteur et un connecteur dépendant du dispositif porte-douille, le connecteur dépendant du dispositif porte-douille étant rigidement solidaire de ce dernier, lesdits moyens de raccordement électrique et lesdits moyens de fixation mécanique coopèrant de manière à assurer la connexion et la déconnexion électrique entre les deux connecteurs respectivement par l'action de montage et de démontage mécanique du dispositif porte-douille par rapport au corps de réflecteur,
caractérisé en ce que les moyens de raccordement électrique de la douille (70) établissent une connexion sur trois conducteurs, permettant respectivement de relier la source lumineuse (71) avec la phase et le neutre, et d'activer la fourniture d'une alimentation haute tension vers la source lumineuse, les moyens de raccordement électrique comprenant trois paires d'éléments de contact (84a-c, 64a-c), chacune comportant un élément de contact (84a-c) au niveau de connecteur fixe (80) et un élément de contact (64a-c) au niveau du connecteur (60) dépendant du dispositif porte-douille, et en ce que la paire d'éléments de contact respectifs (84b, 64b) du connecteur fixe du corps de réflecteur (10) et du connecteur solidaire du dispositif porte-douille qui active la fourniture de l'alimentation haute tension est configurée différemment des autres paires d'éléments de contact (84a, 64a, 84c, 64c) de manière que l'activation de la fourniture de l'alimentation haute tension succède à l'établissement des connexions avec la phase et le neutre durant le montage mécanique du dispositif porte-douille, et que la désactivation de la fourniture de l'alimentation haute tension précède l'interruption desdites connexions avec la phase et le neutre durant le démontage du dispositif porte douille.Thus, an object of the present invention is to remedy these drawbacks by proposing a luminaire intended for public or industrial lighting comprising a reflector body, a removable socket holder device, a socket mounted on the socket holder device, means for mechanically fixing the socket-holder device on the reflector body, allowing the mounting and dismounting of the socket-holder device, and means for electrical connection of the socket-holder device, comprising a fixed connector on the reflector body and a connector dependent on the socket-holder device, the connector dependent on the socket-holder device being rigidly secured to the latter, said electrical connection means and said mechanical fastening means cooperating so as to ensure electrical connection and disconnection between the two connectors respectively by the mechanical assembly and disassembly action of the dou-holder device it in relation to the reflector body,
characterized in that the electrical connection means of the socket (70) establish a connection on three conductors, making it possible respectively to connect the light source (71) with the phase and the neutral, and to activate the supply of a high power supply voltage towards the light source, the electrical connection means comprising three pairs of contact elements (84a-c, 64a-c), each comprising a contact element (84a-c) at the level of the fixed connector (80) and a contact element (64a-c) at the connector (60) depending on the socket-holder device, and in that the pair of respective contact elements (84b, 64b) of the fixed connector of the reflector body (10) and of the connector integral with the socket-holder device which activates the supply of the high-voltage supply is configured differently from the other pairs of contact elements (84a, 64a, 84c, 64c) so that the activation of the supply of the high voltage supply su ccede to the establishment of connections with the phase and the neutral during the mechanical mounting of the socket-holder device, and that the deactivation of the supply of the high voltage supply precedes the interruption of said connections with the phase and the neutral during the disassembly of the socket holder device.

Cette disposition offre non seulement une sécurité plus accrue, mais assure le bon fonctionnement du luminaire lorsque celui-ci utilise un circuit d'amorçage automatique qui comptabilise les impulsions de haute tension à partir de l'établissement du circuit avec alimentation de la source lumineuse par la phase et le neutre.This not only provides more security, but ensures the proper functioning of the luminaire when it uses a circuit automatic ignition which counts the high voltage pulses from of the establishment of the circuit with supply of the light source by the phase and neutral.

Dans tous les cas de figure, et quelque soit le type de circuit d'amorçage utilisé, la conception des connecteurs internes du luminaire assure de la façon la plus naturelle et sûre que le retrait du dispositif porte-douille entraíne automatiquement la déconnexion électrique de la douille. L'opérateur peut alors travailler en toute sécurité pour changer la source lumineuse ou pour effectuer des opérations d'entretien.In all cases, and whatever the type of circuit used, the design of the internal connectors of the luminaire ensures the most natural and safe way that the removal of the socket holder device the electrical disconnection of the socket automatically. The operator can then work safely to change the light source or to perform maintenance operations.

Par ailleurs, la connexion électrique par les connecteurs respectifs du corps de réflecteur du dispositif porte-douille permet de s'affranchir de fils de connexion dépendant du dispositif porte-douille, ce qui facilite le retrait de ce dernier complètement hors du corps de réflecteur. Elle permet en outre de monter la douille sur le dispositif porte-douille dans une position pré-réglée avant l'installation sur site, par exemple en usine. La mise en place de l'ensemble sur le bloc réflecteur ne nécessite alors qu'une seule opération de montage mécanique.Furthermore, the electrical connection by the respective connectors of the reflector body of the socket-holder device eliminates the need for wires connection dependent on the socket holder device, which facilitates the removal of this last completely out of the reflector body. It also allows you to mount the socket on the socket holder in a pre-adjusted position before installation on site, for example in the factory. The installation of the assembly on the reflector block then requires only one mechanical mounting operation.

De préférence, les moyens de fixation mécanique opèrent par un mouvement de rotation du dispositif porte-douille par rapport au corps de réflecteur, par exemple au moyen d'un montage du type baïonnette.Preferably, the mechanical fixing means operate by a rotational movement of the socket holder device relative to the body reflector, for example by means of a bayonet type mounting.

Ce montage est de manipulation particulièrement commode et permet éventuellement de former un joint d'étanchéité d'excellente qualité entre le dispositif porte-douille et son logement dans le corps de réflecteur.This assembly is particularly convenient to handle and allows possibly form an excellent quality seal between the socket holder device and its housing in the reflector body.

Le dispositif porte-douille peut se loger dans une ouverture pratiquée dans une portion de surface du réflecteur, ce qui facilite la fabrication et assure un montage précis du dispositif par rapport aux surfaces réfléchissantes. The socket-holder device can be housed in an opening made in a surface portion of the reflector, which facilitates manufacture and ensures precise mounting of the device in relation to the reflective surfaces.

Lorsqu'il est nécessaire d'assurer une bonne étanchéité entre le réflecteur et le dispositif porte-douille, ce dernier est adapté pour fermer ladite ouverture avec interposition d'un joint d'étanchéité.When it is necessary to ensure a good seal between the reflector and the socket holder device, the latter is adapted to close said socket opening with interposition of a seal.

Dans une configuration particulièrement avantageuse du luminaire, les moyens de montage mécanique de celui-ci sur un support externe sont disposés à une première extrémité du corps de réflecteur, alors que l'ouverture est située vers une deuxième extrémité du corps de réflecteur à l'opposé de la première extrémité.
Le dispositif porte-douille s'introduit alors dans l'ouverture par l'extérieur du réflecteur, permettant d'intervenir au niveau de la source lumineuse et de ses connexions sans être gêné par les éléments de fixation mécanique sur le support du luminaire.In a particularly advantageous configuration of the luminaire, the means for mechanically mounting it on an external support are arranged at a first end of the reflector body, while the opening is situated towards a second end of the reflector body at the opposite of the first end.
The socket holder device is then introduced into the opening from the outside of the reflector, making it possible to intervene at the level of the light source and its connections without being hindered by the mechanical fixing elements on the luminaire support.

De plus, le logement du dispositif porte-douille à l'opposé de la zone de fixation du luminaire permet une utilisation plus rationnelle de l'espace autour du réflecteur, d'où il résulte une amélioration de la compacité du luminaire.In addition, the housing of the socket holder device opposite the area fixture allows a more rational use of space around of the reflector, which results in an improvement in the compactness of the luminaire.

Selon un autre aspect de l'invention, le dispositif porte-douille comporte des moyens pour le réglage de la position de la douille dans le sens de son axe principal.According to another aspect of the invention, the socket holder device includes means for adjusting the position of the socket in the direction of its main axis.

Ce réglage de position de la douille est particulièrement avantageux pour permettre au luminaire de s'adapter à différentes conditions d'utilisation, tant au niveau de la zone à éclairer que des caractéristiques techniques de la source lumineuse ou du réflecteur. Sur le plan industriel, cette flexibilité autorise l'utilisation des mêmes pièces pour satisfaire différents cas d'exploitation, d'où il résulte des économies de production.This adjustment of the position of the socket is particularly advantageous to allow the luminaire to adapt to different conditions of use, both at the level of the area to be lit only technical characteristics of the source light or reflector. On the industrial level, this flexibility allows the use of the same parts to satisfy different operating cases, hence results from production savings.

Le dispositif porte-douille peut en outre comprendre des moyens pour le réglage de position de la douille perpendiculairement à son axe principal dans le sens du rapprochement et de l'éloignement du sommet du réflecteur, autorisant un réglage complémentaire de la source lumineuse.The socket holder device may further comprise means for adjusting the position of the socket perpendicular to its main axis in the direction of approach and away from the top of the reflector, allowing a additional adjustment of the light source.

Selon l'invention, il est également possible de doter le dispositif porte-douille de moyens pour le réglage de l'orientation de l'axe principal de la douille.According to the invention, it is also possible to provide the socket holder device means for adjusting the orientation of the main axis of the sleeve.

Cette disposition permet un ajustement supplémentaire par rapport aux réglages précités, qui est utile entre autres lorsque le luminaire est équipé d'une vasque ayant une faible profondeur, voire un fond plat. Dans ce cas, il est en effet utile de pouvoir orienter l'axe principal de la douille par rapport au fond de la vasque pour le logement de la lampe par rapport à la vasque.This arrangement allows an additional adjustment compared to the aforementioned settings, which is useful inter alia when the luminaire is equipped with a basin with a shallow depth, even a flat bottom. In this case, it is indeed useful to be able to orient the main axis of the socket relative to the bottom of the basin for housing the lamp in relation to the basin.

Le luminaire peut être muni d'une vasque amovible dépendant d'une partie inférieure du corps de réflecteur et d'un capot articulé sur le châssis du corps de réflecteur. Le capot recouvre la surface extérieure du corps de réflecteur ainsi que l'accès au dispositif porte-douille, et comprend un dispositif de fermeture situé à son extrémité libre et qui, en position de fermeture du capot, exerce une force d'appui sur une portion de bord de la vasque pour assurer le maintien de celle-ci.The luminaire can be fitted with a removable basin depending on a lower part of the reflector body and a hinged cover on the body frame reflector. The cover covers the outer surface of the reflector body as well access to the socket holder device, and includes a closure device located at its free end and which, in the closed position of the cover, exerts a force of support on a portion of edge of the basin to ensure the maintenance of this one.

Ainsi, il est possible de démonter la vasque simplement en désengageant le dispositif de fermeture du capot, ce qui permet d'effectuer facilement sur site les changements de vasque et de son joint d'étanchéité. Thus, it is possible to disassemble the basin simply by disengaging the hood closing device, which allows easily on site changes of basin and its seal.

La modularité des éléments du luminaire peut être encore accrue en prévoyant le montage du corps de réflecteur sur une portion de châssis du corps réflecteur par des dispositifs d'encliquetage.The modularity of the luminaire elements can be further increased by providing for mounting of the reflector body on a frame portion of the body reflector by latching devices.

Le luminaire représenté sur les figures 1 à 3 comporte un châssis de corps réflecteur 10 portant un corps de réflecteur 30 qui définit un compartiment fermé 12 avec une vasque transparente 14. Un porte-douille 40, monté dans le corps de réflecteur, du côté avant 10a du châssis du corps réflecteur, fait saillie vers l'arrière à l'intérieur du compartiment 12. Une douille 70 portant une source lumineuse 71 est montée sur le porte-douille 40. The luminaire shown in FIGS. 1 to 3 comprises a frame of reflector body 10 carrying a reflector body 30 which defines a compartment closed 12 with a transparent bowl 14. A socket holder 40, mounted in the reflector body, on the front side 10a of the frame of the reflector body, projects towards the rear inside the compartment 12. A socket 70 carrying a source light 71 is mounted on the socket holder 40.

Du côté de son extrémité arrière 10b, le châssis du corps de réflecteur 10 est monté sur un mât support 90 à travers lequel le luminaire est relié à une source d'énergie extérieure. L'extrémité du mât 90 s'engage dans un manchon 92 bloqué sur le mât au moyen d'un boulon 94. Le corps de réflecteur 10 est fixé sur le manchon 92 au moyen d'un boulon 96 qui traverse une lumière 16a formée au sommet d'une partie de paroi cylindrique 16 à l'arrière du corps de réflecteur. Cette disposition offre une plage de réglage de l'inclinaison générale du corps de réflecteur par rapport au mât support.On the side of its rear end 10b, the chassis of the reflector body 10 is mounted on a support mast 90 through which the luminaire is connected to a external energy source. The end of the mast 90 engages in a sleeve 92 blocked on the mast by means of a bolt 94. The reflector body 10 is fixed to the sleeve 92 by means of a bolt 96 which passes through a lumen 16a formed at top of a cylindrical wall portion 16 behind the reflector body. This layout provides a range of adjustment for the overall tilt of the body reflector with respect to the support mast.

La vasque 14, munie d'un joint d'étanchéité 24 à section en U dans lequel son rebord est engagé, est montée dans un logement du rebord 22 du corps de réflecteur. Dans l'exemple illustré, la vasque 14 est une plaque de verre plane. Elle pourrait être creuse, comme montré en traits interrompus sur la figure 1. Le rebord 22 du corps de réflecteur est verrouillé sur la partie inférieure du châssis 10 du corps de réflecteur en comprimant le joint 24. Le verrouillage est réalisé au moyen de plusieurs organes d'encliquetage 26 comprenant des lames de ressort 26a, solidaires du châssis du corps de réflecteur qui s'encliquettent dans des logements 26b formés sur un rebord 18a entourant l'ouverture 18 formée à la partie inférieure du corps de réflecteur (figure 3).The basin 14, provided with a U-section seal 24 in which its rim is engaged, is mounted in a housing of the rim 22 of the body reflector. In the example illustrated, the basin 14 is a flat glass plate. It could be hollow, as shown in broken lines in Figure 1. The flange 22 of the reflector body is locked on the lower part of the chassis 10 of the reflector body by compressing the seal 24. The locking is carried out at the by means of several latching members 26 comprising spring leaves 26a, integral with the frame of the reflector body which snap into housings 26b formed on a rim 18a surrounding the opening 18 formed at the part bottom of the reflector body (Figure 3).

Le corps de réflecteur 30 comprend une paroi réfléchissante convexe 30a munie à l'avant d'un manchon cylindrique 32 qui entoure une ouverture 32a à travers laquelle s'engage le porte-douille 40 (sur les figures 2 et 3, le porte-douille est omis, ainsi que la douille et la source lumineuse). Comme le montre la figure 3, un autre réflecteur 35 peut être monté à l'intérieur du réflecteur existant 30, ce premier étant verrouillé sur le rebord 18a du corps de réflecteur au moyen de plusieurs dispositifs d'encliquetage 34. Chaque dispositif d'encliquetage comprend une lame de ressort 34a qui est portée par une partie mâle solidaire du corps de réflecteur et s'encliquette dans un logement 34b formé dans une partie femelle solidaire du corps de réflecteur 30. Cette disposition permet notamment d'assembler des réflecteurs spécifiques à chaque type d'application sur des corps de réflecteur universels. Par ailleurs, l'emploi de dispositifs d'encliquetage est particulièrement bien adapté aux chaínes de montage robotisées.The reflector body 30 includes a convex reflecting wall 30a provided at the front with a cylindrical sleeve 32 which surrounds an opening 32a to through which the socket holder 40 engages (in FIGS. 2 and 3, the socket holder is omitted, as well as the socket and the light source). As shown in Figure 3, another reflector 35 can be mounted inside the existing reflector 30, this first being locked on the rim 18a of the reflector body by means of several latching devices 34. Each latching device comprises a leaf spring 34a which is carried by a male part integral with the body of reflector and snaps into a housing 34b formed in a female part integral with the reflector body 30. This arrangement allows in particular to assemble reflectors specific to each type of application on bodies of universal reflector. Furthermore, the use of latching devices is particularly well suited to robotic assembly lines.

La partie supérieure du châssis du corps de réflecteur est fermée par un capot 36 articulé autour d'un axe situé vers l'extrémité arrière 10b du châssis du corps de réflecteur (le capot est omis sur la figure 2). En position ouverte (soulevée), comme montré en traits interrompus sur la figure 1, le capot 36 laisse accès au porte-douille 40 à travers l'ouverture 32a. En position fermée, le capot 36 est verrouillé au moyen d'un crochet articulé 38 qui est situé à l'avant du capot et s'engage dans un logement 23 à l'extrémité avant du rebord 22 du corps de réflecteur.The upper part of the reflector body chassis is closed by a cover 36 articulated around an axis located towards the rear end 10b of the chassis of the reflector body (the cover is omitted in Figure 2). In the open position (raised), as shown in broken lines in Figure 1, the cover 36 leaves access to the socket holder 40 through the opening 32a. In the closed position, the cover 36 is locked by means of an articulated hook 38 which is located at the front of the cover and engages in a housing 23 at the front end of the rim 22 of the body reflector.

Le porte-douille 40, avec la douille 70, ainsi que son montage et son raccordement électrique seront maintenant décrits plus en détail en référence notamment aux figures 4 à 7.The socket holder 40, with the socket 70, as well as its mounting and its electrical connection will now be described in more detail with reference especially in Figures 4 to 7.

Le montage porte-douille 40 dans le manchon 32 du corps de réflecteur est du type à baïonnette.The socket holder assembly 40 in the sleeve 32 of the body reflector is bayonet type.

Le porte-douille 40 comprend une embase 42 prolongée par une bague cylindrique 44 et un support 50 en forme de berceau à section transversale en U. La bague 44 porte à sa périphérie une nervure continue annulaire 46 et une série de nervures 47 en forme d'arcs situées sur une même circonférence. Un joint d'étanchéité torique 48 est logé entre la nervure 46 et l'embase 42.The socket holder 40 comprises a base 42 extended by a ring cylindrical 44 and a support 50 in the form of a cradle with a U-shaped cross section. ring 44 carries at its periphery a continuous annular rib 46 and a series of ribs 47 in the form of arcs located on the same circumference. A joint O-ring seal 48 is housed between the rib 46 and the base 42.

Le porte-douille est engagé à travers le manchon 32 et l'ouverture 32a depuis l'extérieur du corps de réflecteur, le capot 36 étant ouvert. Le manchon 32 porte à sa surface interne une série de nervures 33 en forme d'arcs situées sur une même circonférence. Lors de l'introduction du porte-douille 40, parallèlement à son axe longitudinal, chaque nervure 47 est engagée dans un intervalle entre deux nervures 33. Ensuite, par rotation du porte-douille, les nervures 33 viennent se loger chacune dans l'intervalle entre une nervure 47 et la nervure 46 réalisant un montage du porte-douille par fixation de type baïonnette. Le joint 48 est alors comprimé entre l'embase 42, la nervure 46 et l'extrémité du manchon 32. Le joint 48, avec le joint 24, assure l'étanchéité du compartiment 12.The socket holder is engaged through the sleeve 32 and the opening 32a from outside the reflector body, the cover 36 being open. Sleeve 32 carries on its internal surface a series of ribs 33 in the form of arcs located on a same circumference. When inserting the socket holder 40, parallel to its longitudinal axis, each rib 47 is engaged in an interval between two ribs 33. Then, by rotation of the socket holder, the ribs 33 come each house in the interval between a rib 47 and the rib 46 making a fitting of the socket holder by bayonet type fixing. The seal 48 is then compressed between the base 42, the rib 46 and the end of the sleeve 32. The seal 48, with the seal 24, seals the compartment 12.

Les positions d'introduction ou dégagement du porte-douille et de verrouillage de celui-ci sont définies par les contacts entre une butée 49 solidaire du corps de réflecteur et les extrémités d'une encoche 43 formée dans l'embase 42 (figure 6).The insertion or release positions of the socket holder and locking thereof are defined by the contacts between an integral stop 49 of the reflector body and the ends of a notch 43 formed in the base 42 (figure 6).

La douille 70 est solidaire d'une platine 72 munie d'oreilles 74 par lesquelles elle repose sur les rebords du berceau 50. Ceux-ci sont munis de créneaux 52 dans lesquels s'engagent les oreilles 74 et qui définissent autant de positions possibles de la douille 70 par rapport au porte-douille dans la direction longitudinale du berceau 50. La position de la source lumineuse dans la direction de l'axe principal du réflecteur peut ainsi être ajustée entre deux positions extrêmes illustrées en traits pleins et en traits interrompus sur la figure 1. The socket 70 is integral with a plate 72 provided with ears 74 by which it rests on the edges of the cradle 50. These are provided with slots 52 in which the ears engage 74 and which define as many possible positions of the socket 70 relative to the socket holder in the direction longitudinal of the cradle 50. The position of the light source in the direction of the main axis of the reflector can thus be adjusted between two extreme positions shown in solid lines and broken lines in Figure 1.

Le berceau 50 présente à sa base une lumière longitudinale 54 à travers laquelle passe une vis 56 qui se visse dans la platine 72 pour fixer la douille 70 sur le porte-douille dans la position désirée.The cradle 50 has at its base a longitudinal lumen 54 through which passes a screw 56 which is screwed into the plate 72 to fix the socket 70 on the socket holder in the desired position.

La douille 70 est munie de pattes 76 pour sa fixation au moyen de vis-écrous dans deux lumières 78 de la platine 72. Les lumières 78 sont orientées de manière à permettre un réglage de la douille dans une position plus ou moins éloignée du sommet du réflecteur 30 en direction perpendiculaire à son axe principal.The sleeve 70 is provided with lugs 76 for its fixing by means of screw-nuts in two lights 78 of the plate 72. The lights 78 are oriented from so as to allow adjustment of the socket in a more or less position away from the top of the reflector 30 in a direction perpendicular to its axis main.

Avantageusement, la platine 72, avec la douille 70, peut être montée sur le berceau 50 dans l'une ou l'autre de deux positions décalées l'une de l'autre de 180° en rotation autour de l'axe principal de la douille. A cet effet, les oreilles 74 présentent deux parties opposées 74a, 74b susceptibles chacune de s'engager sans jeu dans un créneau 52.Advantageously, the plate 72, with the socket 70, can be mounted on the cradle 50 in either of two positions offset from each other by 180 ° rotating around the main axis of the socket. For this purpose, the ears 74 have two opposite parts 74a, 74b each capable of engaging without game in a slot 52.

Comme le montre la figure 5, l'oreille 74 est dans un plan incliné d'un angle a par rapport au plan normal à l'axe principal de la douille 70. Ainsi, selon que la platine est montée dans une position ou dans la position inverse, l'axe principal de la douille présente une première ou une deuxième inclinaison différentes l'une de l'autre par rapport à la direction longitudinale du berceau 50. De la sorte, la source lumineuse peut être plus ou moins éloignée de la vasque 14. En particulier, il est possible de choisir une position de la douille pour laquelle l'extrémité de la source lumineuse est plus proche du réflecteur lorsque la vasque est plane et limite l'espace disponible pour la source lumineuse (voir figure 1).As shown in Figure 5, the ear 74 is in an inclined plane at an angle a with respect to the plane normal to the main axis of the sleeve 70. Thus, depending on whether the plate is mounted in a position or in the reverse position, the main axis of the socket has a first or a second inclination different from each other with respect to the longitudinal direction of the cradle 50. In this way, the light source can be more or less distant from the basin 14. In particular, it is possible to choose a position of the socket for which the end of the light source is closer to the reflector when the basin is flat and limits the space available for the light source (see FIG. 1) .

Ce réglage d'inclinaison de la douille, en combinaison avec les réglages de positions offerts par les lumières 78 et par les créneaux 52, permet une adaptation à différentes formes de réflecteurs et de vasques.This tilt adjustment of the socket, in combination with the position settings offered by the lights 78 and by the slots 52, allows a adaptation to different shapes of reflectors and sinks.

L'alimentation électrique de la source lumineuse est assurée par raccordement entre un connecteur 60 solidaire du porte-douille 40 et auquel la douille 70 est reliée par des conducteurs 68, et un connecteur 80 solidaire du corps de réflecteur et auquel aboutit un câble d'alimentation 88 (figure 1) pour liaison à un circuit d'amorçage (non représenté).The light source is supplied with power by connection between a connector 60 secured to the socket holder 40 and to which the socket 70 is connected by conductors 68, and a connector 80 secured to the body reflector and to which leads a power cable 88 (Figure 1) for connection to a priming circuit (not shown).

Avantageusement, les moyens de connexion électrique sont conçus de manière à réaliser la connexion et la déconnexion de la douille 70 simultanément avec le montage et le démontage du porte-douille 40.Advantageously, the electrical connection means are designed to so as to connect and disconnect the socket 70 simultaneously with the assembly and disassembly of the socket holder 40.

Le connecteur 60 est porté à l'extrémité d'un bras 62 solidaire de l'embase 42 du côté de celle-ci opposé à celui muni de la bague 44 et du berceau 50. Le connecteur 60 comprend trois contacts mâles 64a, 64b, 64c destinés à alimenter la source lumineuse respectivement avec la phase, le neutre et la sortie haute tension du circuit d'amorçage. Ces contacts mâles coopèrent avec des contacts femelles respectifs 84a, 84b, 84c du connecteur 80.The connector 60 is carried at the end of an arm 62 integral with the base 42 on the side thereof opposite to that provided with the ring 44 and the cradle 50. The connector 60 comprises three male contacts 64a, 64b, 64c intended for supply the light source with phase, neutral and output respectively high voltage of the ignition circuit. These male contacts cooperate with respective female contacts 84a, 84b, 84c of connector 80.

Les contacts mâles sont orientés parallèlelement à la direction tangentielle à leur trajectoire lors de la rotation du bras 62 provoquée par le montage ou le démontage de la fixation à baïonnette du porte-douille. Pour tenir compte du fait que le déplacement des contacts mâles n'est pas exactement rectiligne, le bloc constituant le connecteur 80 peut être réalisé en un matériau déformable élastiquement.Male contacts are oriented parallel to the direction tangential to their trajectory during the rotation of the arm 62 caused by the mounting or dismounting the bayonet fitting of the socket holder. To hold account for the fact that the displacement of the male contacts is not exactly straight, the block constituting the connector 80 can be made of a material elastically deformable.

Pour éviter toute déconnexion accidentelle que pourrait provoquer les vibrations, par exemple, un bossage 36a dépendant du capot 36 prend appui contre l'embase 42, au niveau de l'extrémité du bras 62 où se trouve le connecteur 60, lorsque le capot est en position fermée (figure 1).To avoid any accidental disconnection that could cause vibrations, for example, a boss 36a depending on the cover 36 bears against the base 42, at the end of the arm 62 where the connector 60 is located, when the cover is in the closed position (Figure 1).

De préférence, les contacts sont réalisés de manière que l'alimentation haute tension soit établie en dernier lors de la connexion et interrompue en premier lors de la déconnexion. Ceci est réalisé par exemple en conférant au contact mâle correspondant 64b une longueur inférieure à celle des deux autres contacts mâles 64, 64c, les contacts femelles étant identiques (figure 7).Preferably, the contacts are made so that the supply high voltage is established last during connection and interrupted first when disconnecting. This is done for example by conferring on male contact corresponding 64b to a length less than that of the other two male contacts 64, 64c, the female contacts being identical (Figure 7).

On notera encore que le connecteur 60 est disposé à l'intérieur d'un logement 66 à l'extrémité du bras 62, logement dont la paroi entoure les contacts mâles. Le logement 66 est accessible à travers une ouverture dans laquelle s'engage le bloc 80 portant les contacts femelles. Ce dernier est muni à sa périphérie d'une lèvre d'étanchéité 86 qui coopère avec la paroi du logement 66 pour isoler les contacts et les protéger de la saleté et de l'humidité lorsque la connexion est établie.It will also be noted that the connector 60 is arranged inside a housing 66 at the end of the arm 62, housing whose wall surrounds the contacts males. The housing 66 is accessible through an opening in which engages block 80 carrying the female contacts. The latter is provided at its periphery with a sealing lip 86 which cooperates with the wall of the housing 66 to isolate the protect them from dirt and moisture when the connection is established.

Le fonctionnement électrique des moyens de connexion selon l'invention sera maintenant expliqué en référence aux figures 8 et 9. Ces figures représentent deux exemples de circuit d'alimentation et de connexion de la source lumineuse 71 du luminaire. Les deux circuits représentés comprennent les mêmes éléments et ne diffèrent qu'au niveau des interconnexions.The electrical operation of the connection means according to the invention will now be explained with reference to Figures 8 and 9. These figures represent two examples of supply circuit and connection of the source luminous 71 of the luminaire. The two circuits shown include the same elements and differ only at the interconnection level.

Dans les deux figures, le raccordement électrique de la source lumineuse 71 avec les éléments de connexion mâles 64a-64c et femelles 84a-84c de la figure 7 est représenté schématiquement. L'alimentation de la source lumineuse 71 par la phase P et le neutre N s'opère respectivement par les paires d'éléments 64a, 84a et 64c, 84c. De manière classique, l'alimentation extérieure du réseau est conditionnée par un condensateur 100 de correction de facteur de puissance (cos phi) connecté entre la phase P et le neutre N, et un ballast 102 connecté en série entre l'alimentation extérieure de la phase P et les éléments de contacts 64a, 84a de la source lumineuse 71.In the two figures, the electrical connection of the source light 71 with male connection elements 64a-64c and female 84a-84c of Figure 7 is shown schematically. Source power light 71 by phase P and neutral N operates respectively by pairs of elements 64a, 84a and 64c, 84c. Conventionally, the external supply of the network is conditioned by a 100 factor correction capacitor power (cos phi) connected between phase P and neutral N, and a ballast 102 connected in series between the external supply of phase P and the elements of contacts 64a, 84a of the light source 71.

Un circuit d'amorçage 104 est prévu dans le circuit d'alimentation pour créer des impulsions de haute tension lors du démarrage de la source lumineuse 71. Le circuit d'amorçage 104 est alimenté en phase et en neutre sur des entrées respectives 104a et 104b. Il émet les impulsions sur une sortie 104c qui est reliée directement à l'arrivée de la phase sur l'élément de contact femelle 84a, celui-ci étant également relié au ballast 102.A priming circuit 104 is provided in the supply circuit for create high voltage pulses when starting the light source 71. Priming circuit 104 is supplied in phase and neutral on inputs 104a and 104b respectively. It emits the pulses on an output 104c which is connected directly at the arrival of the phase on the female contact element 84a, this also being connected to ballast 102.

Le circuit d'amorçage 104 peut être temporisé, envoyant les impulsions pendant un temps limité à partir de l'instant où il est alimenté, ce temps étant fixé soit par une horloge, soit par un compteur d'impulsions. Cependant, le circuit d'amorçage peut être du type simple, sans temporisation.The priming circuit 104 can be timed, sending the pulses for a limited time from the moment it is supplied, this time being fixed either by a clock or by a pulse counter. However, the circuit priming can be of the simple type, without delay.

Dans le montage de la figure 8, l'alimentation en phase du circuit d'amorçage 104 est assurée par une dérivation 102a sur l'enroulement du ballast 102. La connexion du circuit d'amorçage au neutre s'effectue à travers la paire d'éléments de contact 64b, 84b. L'élement de contact mâle 64b est câblé directement sur l'élément de contact mâle 64c qui alimente le neutre de la source lumineuse. Ainsi, l'élément de contact 64b n'est en présence du neutre que lorsque l'élémént de contact mâle 64c est relié à l'élément de contact femelle 84c, qui est lui-même relié directement avec le neutre du réseau.In the assembly of figure 8, the phase supply of the circuit priming 104 is provided by a bypass 102a on the ballast winding 102. The connection of the ignition circuit to neutral is made through the pair contact elements 64b, 84b. Male contact element 64b is wired directly on the male contact element 64c which supplies the neutral of the source bright. Thus, the contact element 64b is in the presence of the neutral only when the male contact element 64c is connected to the female contact element 84c, which is itself directly connected with the network neutral.

La connexion et la déconnexion de l'alimentation du circuit d'amorçage 104 par le neutre s'effectuent respectivement après et avant la connexion de la source lumineuse 71 au neutre N. Cette connexion séquentielle est réalisée par la différence de configuration des éléments de contact 64b, 84b de la connexion du circuit d'amorçage 104 au neutre, par rapport aux autres pairs d'éléments de contact (64a, 84a ou 64c, 84c) assurant l'alimentation en phase et en neutre de la source lumineuse.Connection and disconnection of the circuit supply 104 by neutral are carried out respectively after and before the connection of light source 71 to neutral N. This sequential connection is achieved by the difference in configuration of the contact elements 64b, 84b of the connection of the ignition circuit 104 to neutral, with respect to the other peers contact elements (64a, 84a or 64c, 84c) ensuring the supply in phase and in light source neutral.

Dans l'exemple, la différence de configuration est réalisée en rendant l'élément de contact mâle 64b plus court que les autres éléments de contact mâles 64a, 64c, tout en gardant la même géométrie pour les autres pièces de connexion.In the example, the configuration difference is achieved by making the male contact element 64b shorter than the other male contact elements 64a, 64c, while keeping the same geometry for the other connection parts.

Le fonctionnement du circuit d'alimentation et la connexion séquentielle seront maintenant expliqués en référence à la figure 8.The functioning of the supply circuit and the connection sequential will now be explained with reference to Figure 8.

On prendra comme situation de départ la déconnexion de la source lumineuse 71 (par le démontage du dispositif porte-douille 40) alors qu'elle est allumée depuis un certain temps, le circuit d'amorçage 104 étant donc au repos. Lors de la déconnexion séquentielle, le circuit d'amorçage 104 est débranché en premier, par le retrait de l'élément de connexion mâle 64b de l'élément de connexion femelle 84b, mais la source lumineuse 71 reste momentanément allumée. Ensuite, la source lumineuse est débranchée, mais à ce moment le circuit d'amorçage n'envoie pas d'impulsions de haute tension sur les éléments de contact d'alimentation en phase 64a, 84a. La sécurité du personnel est ainsi assurée.We will take as source situation the disconnection of the source light 71 (by dismantling the socket holder device 40) while it is lit for some time, the priming circuit 104 is therefore at rest. During the sequential disconnection, the priming circuit 104 is disconnected in first, by removing the male connection element 64b from the element female connection 84b, but the light source 71 remains momentarily on. Then the light source is disconnected, but at this time the circuit does not send high voltage pulses to the contact elements supply phase 64a, 84a. Staff safety is thus ensured.

On prendra maintenant comme situation de départ la déconnexion de la source lumineuse 71 en état éteint. On suppose que l'état éteint provient du fait que le circuit d'amorçage 104 n'a pas réussi à faire démarrer la source lumineuse 71 durant son cycle d'envoi d'impulsions de haute tension. Il s'agit là du symptome classique de la fin de vie de la source lumineuse, nécessitant son remplacement.We will now take the disconnection of the light source 71 in off state. We assume that the extinct state comes from the fact that the priming circuit 104 has failed to start the light source 71 during its cycle of sending high voltage pulses. This is the symptom classic of the end of life of the light source, requiring its replacement.

Lors de la déconnexion, le circuit d'amorçage 104 est débranché en premier, comme expliqué précédemment. Cette déconnexion a pour effet d'initialiser la comptabilisation des impulsions de haute tension du circuit d'amorçage et de désactiver ce dernier. Ensuite, la source lumineuse 71 est débranchée en l'absence de toute source de haute tension.Upon disconnection, the priming circuit 104 is disconnected by first, as previously explained. This disconnection has the effect initialize the accounting of high voltage pulses in the circuit and deactivate it. Then, the light source 71 is disconnected in the absence of any high voltage source.

Quand une nouvelle source lumineuse est mise place, les contacts entre les éléments 64a, 84a et 64c, 84c sont établis en premier lieu. Le contact entre les éléments 64b, 84b s'effectue ensuite et active le circuit d'amorçage 104. Ainsi, les impulsions haute tension ne seront transmises qu'une fois que la nouvelle source lumineuse est connectée.When a new light source is installed, the contacts between elements 64a, 84a and 64c, 84c are established first. Contact between elements 64b, 84b is then carried out and activates the priming circuit 104. Thus, the high voltage pulses will only be transmitted once the new source light is connected.

On notera qu'une source lumineuse non amorcée se comporte comme un circuit ouvert, et il n'y a donc aucun courant dans les contacts 64a, 84a, 64c, 84c au moment de la connexion. Le courant dans le contacts 64b, 84b est très faible (de l'ordre de quelques dizaines de milliampères).Note that an un-primed light source behaves as an open circuit, and therefore there is no current in the contacts 64a, 84a, 64c, 84c at the time of connection. The current in contacts 64b, 84b is very low (of the order of a few tens of milliamps).

Ainsi, la présente connexion séquentielle permet d'intervenir sur site en parfaite sécurité dans tous les cas de figures de fontionnement, et toujours en assurant le re-démarrage du circuit d'amorçage.Thus, the present sequential connection makes it possible to intervene on site by perfect safety in all operating cases, and always in ensuring the restarting of the priming circuit.

Il est à remarquer dans les dispositions de l'art antérieur, le remplacement d'une source lumineuse usagée par une neuve ne s'accompagnait pas nécessairement du rallumage de celle-ci, le circuit d'amorçage n'étant pas automatiquement ré-initialisé. De la sorte, il arrivait souvent que le circuit d'amorçage soit diagnostiqué à tort comme étant défaillant, car son remplacement par un circuit neuf (et donc initialisé) faisait démarrer la source lumineuse. Or, le circuit d'amorçage n'avait simplement pas été remis à zéro et était renvoyé au fournisseur comme pièce défaillante. It should be noted in the provisions of the prior art, the replacement of a used light source with a new one was not accompanied necessarily reignition thereof, the priming circuit not being automatically re-initialized. In this way, it often happened that the circuit is incorrectly diagnosed as faulty, because its replacement by a new circuit (and therefore initialized) started the light source. However, the priming circuit simply had not been reset and was returned to the supplier as faulty part.

La disposition des contacts des contacts effectue donc une ré-initialisation du circuit d'amorçage au moment de la déconnexion sous tension et, qui plus est, la séquence des contacts évite l'application de la haute tension d'amorçage au moment de l'établissement des contacts.The arrangement of the contacts of the contacts therefore performs a reinitialization of the ignition circuit at the time of disconnection under voltage and, moreover, the sequence of contacts avoids the application of high voltage at the time of contact establishment.

Le circuit de la figure 9 diffère de celui de la figure 8 essentiellement par le fait que le circuit d'amorçage 104 est alimenté directement à la sortie du ballast 102, et est donc connecté en série entre le ballast et les contacts de la phase 64a, 84a de la source lumineuse 71. Dans ce type de montage, on utilise généralement des circuits d'amorçage 104 qui ne comptabilisent pas le nombre ou la durée des impulsions de haute tension.The circuit of Figure 9 differs from that of Figure 8 essentially by the fact that the priming circuit 104 is supplied directly at the output of the ballast 102, and is therefore connected in series between the ballast and the phase contacts 64a, 84a of the light source 71. In this type of assembly, use is made generally initiation circuits 104 which do not count the number or the duration of the high voltage pulses.

Toutefois, même dans ce cas, la connexion séquentielle selon l'invention apporte toujours le bénéfice de la sécurité du personnel d'entretien en raison de l'absence de haute tension pendant la connexion ou la déconnexion du dispositif porte-douille 40.However, even in this case, the sequential connection according to the invention still provides the benefit of the safety of maintenance personnel in due to the absence of high voltage during connection or disconnection of the socket holder 40.

L'invention n'est nullement limitée au mode de réalisation qui vient d'être décrit, mais permet de nombreuses variantes.The invention is in no way limited to the embodiment which comes to be described, but allows many variations.

Par exemple, la fixation mécanique du porte-douille 40 peut être réalisée par vissage sur une fraction de tour, plutôt que par un montage du type baïonnette.For example, the mechanical fixing of the socket holder 40 can be performed by screwing on a fraction of a turn, rather than by a mounting of the type bayonet.

Il est également possible de modifier l'agencement de ces moyens de fixation pour que le montage et le démontage du porte-douille 40 s'opèrent suivant un trajet rectiligne dans la direction d'insertion. Dans ce cas, le porte-douille 40 pourra être retenu dans le corps de réflecteur 30 par encliquetage ou par connexion entre des éléments mâles et femelles. Les contacts des connecteurs électriques seront alors alignés dans la direction d'insertion du porte-douille.It is also possible to modify the arrangement of these means of fixing so that the assembly and disassembly of the socket holder 40 takes place according to a straight path in the direction of insertion. In this case, the socket holder 40 can be retained in the reflector body 30 by snap-fastening or by connection between male and female elements. Contacts of electrical connectors will then be aligned in the direction of insertion of the socket holder.

Par ailleurs, le réglage de la position longitudinale de la douille pourra être réalisé par montage de la douille dans une glissière du porte-douille le long de laquelle la douille peut être déplacée et serrée par tout moyen connu de l'homme du métier.Furthermore, the adjustment of the longitudinal position of the bushing may be made by mounting the socket in a slide of the socket holder along which the sleeve can be moved and tightened by any means known to man of career.
