Description

La présente invention est relative aux projecteurs de véhicules automobiles, et plus particulièrement aux projecteurs du type à lampe à décharge.The present invention relates to automotive headlights, and more particularly to headlamp type projectors dump.

Les projecteurs de véhicules automobiles à lampe à décharge sont alimentés par des courants alternatifs, de préférence de forme carrée, ce qui permet d'augmenter de façon notable la durée de vie des lampes.Lamp headlamps for motor vehicles to discharge are powered by alternating currents, preferably square, which increases notably the lifetime of the lamps.

Toutefois, du fait de la richesse des harmoniques présents dans un signal d'alimentation carrée, ces projecteurs émettent des signaux électromagnétiques parasites, nuisibles à l'environnement électronique du véhicule. De tels signaux parasites sont par exemple susceptibles de perturber l'électronique de contrôle du moteur, le système anti-blocage des freins, les auto-radios, etc.However, due to the wealth of harmonics present in a power signal square, these projectors emit signals electromagnetic interference, harmful to the vehicle's electronic environment. Such spurious signals are for example likely to disturb the engine control electronics, the anti-lock braking system, car radios, etc.

Pour résoudre ce problème, il est déjà connu de réaliser un blindage des fils d'alimentation.To solve this problem, it is already known to shield the supply wires.

Toutefois, cette solution ne permet pas de réduire l'émission propre aux éléments à l'intérieur du projecteur, et notamment les émissions de la lampe, via. son culot.However, this solution does not allow reduce the emission specific to the elements inside the projector, and in particular the lamp emissions, via. his base.

Il a également été proposé d'enfermer la lampe du projecteur dans une cage de FARADAY constituée du réflecteur du projecteur et de la glace avant de celui-ci, ladite glace étant armée d'un grillage réalisé par des fils métalliques de faible diamètre.It was also proposed to enclose the lamp of the projector in a FARADAY cage made up of headlamp reflector and front glass this one, said glass being armed with a mesh made by metallic wires of small diameter.

Cependant, avec cette solution, la transmission optique de la glace armée est atténuée de façon importante, puisqu'elle n'est plus que de l'ordre de 60 à 70 %. Cette chute de transmission fait perdre à la lampe à décharge une partie de son intérêt principal, qui est de procurer un flux lumineux élevé.However, with this solution, the transmission reinforced ice optics are attenuated so important, since it is only around 60 at 70%. This drop in transmission causes the discharge lamp part of its main interest, which is to provide a high luminous flux.

En outre, la lumière est diffractée sur chacune des mailles du grillage, ce qui créé des éblouissements incompatibles avec les prescriptions réglementaires.In addition, the light is diffracted on each chain link mesh, which creates glare incompatible with regulatory requirements.

Un but de l'invention est donc de proposer un projecteur de véhicule automobile dont les sources de bruits parasites sont réduites, sans que les performances optiques du projecteur ne se trouvent atténuées.An object of the invention is therefore to propose a motor vehicle headlamp whose sources of noise is reduced, without the projector optical performance can only be found mitigated.

A cet effet, elle propose un projecteur à lampe à décharge pour véhicule automobile comportant un réflecteur concave dans le fond duquel est disposée une lampe à décharge, ainsi qu'un occulteur, (Projecteur du type divulgué, par exemple, par WO-A-91/15711 ou DE-A-19611308 caractérisé en ce que l'occulteur est relié à la masse.For this purpose, it offers a lamp projector discharge for a motor vehicle comprising a concave reflector in the bottom of which is arranged a discharge lamp, as well as a concealer, (Projector of the type disclosed, for example, by WO-A-91/15711 or DE-A-19611308 characterized in what the concealer is connected to ground.

Ce projecteur est avantageusement complété par les différentes caractéristiques suivantes prises seules ou selon toutes leurs combinaisons techniquement possibles :

  • la face interne du réflecteur est reliée à la masse ;
  • l'occulteur est fixé mécaniquement par rapport au réflecteur par l'intermédiaire de pattes de fixation, qui sont en appui sur la face interne dudit réflecteur ;
  • au moins une patte de fixation traverse le réflecteur, son extrémité à l'extérieur du réflecteur coopérant avec des moyens complémentaires pour assurer la fixation de ladite patte par rapport au réflecteur.
This projector is advantageously supplemented by the following different characteristics taken alone or in all their technically possible combinations:
  • the internal face of the reflector is connected to ground;
  • the screen is mechanically fixed relative to the reflector by means of fixing lugs, which are supported on the internal face of said reflector;
  • at least one fixing lug passes through the reflector, its end outside the reflector cooperating with complementary means to ensure the fixing of said lug relative to the reflector.

D'autres caractéristiques et avantages de l'invention ressortiront encore de la description qui suit. Cette description est purement illustrative et non limitative. Elle doit être lue en regard des dessins annexés sur lesquels :

  • la figure 1 est une représentation schématique en coupe d'un projecteur conforme à un mode de réalisation possible pour l'invention ;
  • la figure 2 est une représentation schématique en coupe d'un projecteur conforme à un deuxième mode de réalisation possible pour l'invention ;
  • la figure 3 est une représentation schématique en coupe d'un troisième mode de réalisation possible de l'invention.
Other characteristics and advantages of the invention will emerge from the description which follows. This description is purely illustrative and not limiting. It must be read in conjunction with the appended drawings in which:
  • Figure 1 is a schematic sectional representation of a projector according to a possible embodiment for the invention;
  • Figure 2 is a schematic sectional view of a projector according to a second possible embodiment for the invention;
  • Figure 3 is a schematic sectional representation of a third possible embodiment of the invention.

Le projecteur illustré sur la figure 1 comporte principalement un réflecteur 1, une lampe 2 et un occulteur 3. The projector illustrated in Figure 1 includes mainly a reflector 1, a lamp 2 and a concealer 3.

Le réflecteur 1 a classiquement une forme concave qui réfléchit la lumière émise par la lampe 2 de façon à ce qu'elle sorte du projecteur selon un faisceau dirigé. Cette forme concave est par exemple une forme paraboloïde ou autre, dont un foyer est disposé à proximité de la lampe 2.The reflector 1 conventionally has a shape concave which reflects the light emitted by the lamp 2 of so that it comes out of the spotlight in a beam directed. This concave shape is for example a shape dish or other, a focus of which is arranged at near the lamp 2.

Ce réflecteur 1 est par exemple constitué par une tôle ou une paroi en une matière plastique, sur laquelle est déposé un film d'aluminium.This reflector 1 is for example constituted by a sheet or wall made of plastic, on which is deposited an aluminum film.

La lampe 2 est par exemple une lampe à décharge aux iodures de sodium.The lamp 2 is for example a discharge lamp with sodium iodides.

On a représenté schématiquement sur la figure 1 son tube à décharge 2a, et son culot d'alimentation 2b. Le tube à décharge 2a s'étend à l'intérieur du réflecteur 1, à partir de son fond, selon l'axe dudit réflecteur 1 ; le culot 2b d'alimentation s'étend à l'extérieur du réflecteur 1, à partir du fond de celui-ci et est en appui direct sur ledit réflecteur 1.There is shown schematically in Figure 1 its discharge tube 2a, and its supply base 2b. The discharge tube 2a extends inside the reflector 1, from its bottom, along the axis of said reflector 1; the supply base 2b extends to outside of reflector 1, from the bottom of the latter and is in direct contact with said reflector 1.

Une bague métallique annulaire 4 entoure le tube à décharge 2 à proximité du réflecteur 1. Cette bague métallique 4 est, ainsi que cela sera décrit plus loin plus en détails, reliée à la masse commune du système, sur laquelle sont reliés les différentes masses et pièces de blindage des différents composants du système électronique (ballast de commande, connectique 12 V et haute tension, etc, ...). Cette bague 4 sert à capter les émissions électromagnétiques de la lampe 2.An annular metal ring 4 surrounds the tube discharge 2 near the reflector 1. This ring metallic 4 is, as will be described later in more detail, linked to the common ground of the system, on which the different masses are connected and shielding parts of the various system components electronic (control ballast, 12 V connectors and high voltage, etc.). This ring 4 is used to capture electromagnetic emissions from the lamp 2.

Plus précisément, cette bague métallique 4 se termine par un rebord annulaire extérieur 4a qui, lorsque la bague 4 est en place sur le réflecteur 1, est interposé entre la face externe du réflecteur et un rebord 5 que présente le culot 2b de la lampe.More specifically, this metal ring 4 is ends with an outer annular rim 4a which, when the ring 4 is in place on the reflector 1, is interposed between the external face of the reflector and a rim 5 that has the base 2b of the lamp.

Le réflecteur 1 présente, sur sa face externe, une ou plusieurs protubérances 1a - qui servent au positionnement de la lampe - contre lesquelles le rebord 5 du culot 2b vient en appui, ces protubérances étant par ailleurs destinées à s'engager dans un orifice complémentaire que présente le rebord annulaire 4a de la bague 4, pour maintenir ladite bague 4 en place par rapport au réflecteur 1.The reflector 1 has, on its external face, one or more protrusions 1a - which are used for lamp positioning - against which edge 5 of the base 2b comes to bear, these protuberances being moreover intended to engage in an orifice that the annular rim 4a of the ring 4, to hold said ring 4 in place by relative to reflector 1.

Le cache 3 formant occulteur est maintenu en place par rapport au réflecteur 1 par l'intermédiaire de deux pattes de fixation 6 s'étendant entre ledit occulteur 3 et le réflecteur 1, ces pattes 6 étant réparties de part et d'autre du tube à décharge 2a.The cover 3 forming a concealer is held in place in relation to reflector 1 via two fixing lugs 6 extending between said blackout 3 and reflector 1, these tabs 6 being distributed on either side of the discharge tube 2a.

Ces pattes de fixation 6 sont des pattes métalliques. Elles sont, à leur extrémité opposée à l'occulteur 3, en appui contre la face aluminée du réflecteur 1, au moins l'une de ces pattes 6 traversant ledit réflecteur 1 au niveau d'un orifice 7 que celui-ci présente (trou de fond ou alésage spécifique).These fixing lugs 6 are lugs metal. They are, at their end opposite to the screen 3, pressing against the aluminized face of the reflector 1, at least one of these legs 6 passing through said reflector 1 at an orifice 7 that the latter present (bottom hole or specific bore).

Cette patte 6 traversante est reliée soit à la bague située autour du culot 2b - par exemple par soudure de son extrémité sur le bord 4a - soit à une prise de masse à l'extérieur du réflecteur 1.This through leg 6 is connected either to the ring located around the base 2b - for example by soldering of its end to the edge 4a - either at a ground connection outside the reflector 1.

Ainsi, la face aluminée du réflecteur 1 et l'occulteur 3 - qui sont tous deux susceptibles de constituer des antennes d'émission de rayonnements électromagnétiques nuisibles - sont tous deux reliés à la masse, ce qui empêche toute émission.Thus, the aluminized face of the reflector 1 and blackout 3 - both of which are likely to constitute radiation emission antennas harmful electromagnetic - are both related to mass, which prevents any emission.

La fixation de l'occulteur 3 sur le réflecteur 1 peut être réalisée au moyen de la bague 4, les pattes 6 étant griffées au travers du rebord 4a de ladite bague 4 pour assurer en même temps la mise à la masse de l'occulteur 3 et le maintien mécanique dudit occulteur 3.Attaching the shield 3 to the reflector 1 can be achieved by means of the ring 4, the tabs 6 being scratched through the rim 4a of said ring 4 to ensure at the same time the grounding of the concealer 3 and the mechanical retention of said concealer 3.

Une autre variante de réalisation a encore été illustrée sur la figure 2.Another alternative embodiment has been illustrated in figure 2.

On a repris pour les éléments du projecteur de la figure 1 que l'on retrouve sur le projecteur de la figure 2, la même numérotation de référence augmentée de 10.We took over for the elements of the projector from Figure 1 found on the projector of the Figure 2, the same reference numbering increased by 10.

Ce projecteur comporte un réflecteur 11, une lampe à décharge 12 qui présente un tube 12a et un culot 12b, ainsi qu'un occulteur 13 fixé par rapport au réflecteur 11 par l'intermédiaire de pattes de fixation 16.This projector has a reflector 11, a discharge lamp 12 which has a tube 12a and a base 12b, as well as a concealer 13 fixed relative to the reflector 11 by means of fixing lugs 16.

Une bague métallique 14 reliée à la masse entoure la partie 12a de la lampe à décharge. Cette bague métallique 14 ne comporte pas de rebord annulaire semblable au rebord 4a, mais est fixée sur le projecteur par l'intermédiaire de pattes 18 qui s'étendent radialement à partir de la face externe de ladite bague 14 jusqu'aux pattes de fixation 16 de l'occulteur.A metal ring 14 connected to earth surrounds part 12a of the discharge lamp. This metal ring 14 does not have an annular rim similar to ledge 4a, but is fixed to the spotlight via legs 18 which extend radially from the outer face of said ring 14 to the fixing lugs 16 of the screen.

L'occulteur 13 est par exemple fixé sur le réflecteur 11 par rabattement de pattes 16 sur des protubérances 19 sur la face arrière de celui-ci, ces pattes 16 étant par ailleurs en contact avec la face aluminée du réflecteur 11.The screen 13 is for example fixed on the reflector 11 by folding legs 16 on protrusions 19 on the rear side thereof, these legs 16 being otherwise in contact with the face aluminized reflector 11.

Au moins l'une des pattes 16 est reliée à la masse, de sorte que la face aluminée du réflecteur 11, la bague 14 et l'occulteur 13 sont tout deux à la masse.At least one of the legs 16 is connected to the mass, so that the aluminized face of the reflector 11, the ring 14 and the concealer 13 are both grounded.

L'occulteur 13 est en appui par l'intermédiaire de ces pattes de fixation 16 sur le réflecteur 11, ce qui empêche les mouvements de l'occulteur 13 vers l'arrière du réflecteur.The concealer 13 is in support via of these fixing lugs 16 on the reflector 11, this which prevents the movements of the screen 13 towards the back of the reflector.

Une autre variante de réalisation de l'invention a encore été illustrée sur la figure 3.Another variant embodiment of the invention was further illustrated in Figure 3.

On a repris pour les éléments de la variante de la figure 1 qui se retrouve sur cette variante les mêmes numérotations de référence augmentées de 20.We took over for the elements of the variant of Figure 1 which is found on this variant the same reference numbering increased by 20.

Comme dans le cas de la variante illustrée sur la figure 2, la bague 24 est fixée aux pattes de fixation 26 par des éléments qui s'étendent radialement.As in the case of the variant illustrated on Figure 2, the ring 24 is fixed to the legs of fixing 26 by elements which extend radially.

Les pattes de fixation 26 sont traversantes par rapport au réflecteur 21 et rabattues en tout ou partie sur une couronne métallique 30, fixée par vissage sur le réflecteur 21.The fixing lugs 26 pass through through relative to reflector 21 and folded in whole or in part on a metal crown 30, fixed by screwing on the reflector 21.

La prise de masse commune est alors disposée soit sur l'une des pattes de fixation 26 de l'occulteur 23, soit sur la couronne métallique vissée 29. The common ground connection is then placed either on one of the fixing lugs 26 of the screen 23, either on the screwed metal crown 29.

En variante encore, il peut être prévu que la prise de masse s'effectue par le masque métallisé du réflecteur.As a further variant, it can be provided that the weight gain is achieved by the metallic mask of the reflector.
