Abstract
Description
La présente invention est relative aux projecteurs de véhicule automobile à fonction virage. The present invention relates to motor vehicle headlights with cornering function.
Des projecteurs de ce type ont notamment déjà été décrits dans les demandes de brevet FR 2 626 959,
FR 2 626 652 et FR 2 577 014.Projectors of this type have in particular already been described in patent applications FR 2 626 959,
FR 2 626 652 and FR 2 577 014.
Les projecteurs décrits dans ces demandes de brevet comportent des réflecteurs paraboliques à l'intérieur desquels sont disposés des réflecteurs mobiles dont l'orientation est commandée de façon que le faisceau qu'ils réfléchissent éclaire, lorsque le véhicule se déplace sur une trajectoire incurvée, les portions de route qui sont destinées à être abordées par le véhicule et qui se trouvent devant et sur le côté de celui-ci. The headlights described in these patent applications include parabolic reflectors inside which are arranged movable reflectors whose orientation is controlled so that the beam which they reflect illuminates, when the vehicle is moving on a curved path, the sections of road which are intended to be approached by the vehicle and which are located in front of and on the side thereof.
Comme on l'aura compris, ces projecteurs - et notamment les mécanismes de basculement de leurs réflecteurs mobiles - sont d'une structure particulièrement compliquée. As will be understood, these projectors - and in particular the tilting mechanisms of their movable reflectors - are of a particularly complicated structure.
En outre, ces projecteurs ne permettent pas un débattement important de l'orientation des faisceaux de virage. Ce débattement est en effet limité à + 200. In addition, these headlamps do not allow significant movement of the orientation of the turning beams. This travel is indeed limited to + 200.
On connaît également par US 5 412 543 un projecteur à fonction virage dont le réflecteur est elliptique et est mobile en pivotement par rapport à un cache et à une lentille de sortie du projecteur, autour d'un axe qui est perpendiculaire à l'axe dudit réflecteur et qui passe par celui-ci. Là aussi, l'entraînement du réflecteur mobile nécessite un mécanisme complexe et encombrant. Also known from US 5,412,543 is a headlight with a turning function, the reflector of which is elliptical and is pivotally movable relative to a cover and to an exit lens of the headlight, about an axis which is perpendicular to the axis of said head. reflector and going through it. Again, driving the movable reflector requires a complex and bulky mechanism.
Un but de l'invention est de proposer une structure de projecteur à fonction virage qui est d'une grande simplicité, d'un encombrement faible et qui présente de bonnes performances photométriques et mécaniques, en permettant notamment des débattement satisfaisants pour les faisceaux de la fonction virage. An object of the invention is to provide a headlamp structure with a bend function which is very simple, of small bulk and which has good photometric and mechanical performance, in particular allowing satisfactory clearance for the beams of the turn function.
Selon l'invention, ce but est atteint avec un projecteur à fonction virage pour véhicule automobile comportant un réflecteur elliptique, une source lumineuse disposée au foyer dudit réflecteur et une lentille de convergence, caractérisé en ce qu'il comporte également un miroir de renvoi qui est disposé sur le trajet optique du faisceau réfléchi par le réflecteur elliptique et qui est pivotant par rapport au réflecteur et à la lentille autour d'un axe qui est sensiblement perpendiculaire à l'axe du réflecteur, ainsi qu'à l'axe du véhicule. According to the invention, this object is achieved with a headlight with a turning function for a motor vehicle comprising an elliptical reflector, a light source disposed at the focus of said reflector and a convergence lens, characterized in that it also comprises a deflection mirror which is arranged on the optical path of the beam reflected by the elliptical reflector and which is pivotable relative to the reflector and to the lens about an axis which is substantially perpendicular to the axis of the reflector, as well as to the axis of the vehicle .
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 de la figure unique annexée qui illustre schématiquement un projecteur à fonction virage conforme à un 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 should be read with reference to the single appended figure which schematically illustrates a headlamp with bend function in accordance with a possible embodiment of the invention.
Le projecteur illustré sur la figure 1 comporte un réflecteur elliptique 1, une source 2, une lentille de convergence 3, ainsi qu'un miroir de renvoi 4. The projector illustrated in FIG. 1 comprises an elliptical reflector 1, a source 2, a convergence lens 3, as well as a deflection mirror 4.
Ces différents éléments sont montés dans un boîtier fermé par une glace, ce boîtier et cette glace n'ayant pas été représentés pour ne pas surcharger la figure 1. These various elements are mounted in a housing closed by a glass, this housing and this glass not having been shown so as not to overload FIG. 1.
Le réflecteur elliptique 1 est par exemple moulé en un matériau plastique, sa surface de réflexion étant réalisée par métallisation ou peinture. The elliptical reflector 1 is for example molded from a plastic material, its reflection surface being produced by metallization or painting.
Lorsque le projecteur est en place sur un véhicule, l'axe dudit réflecteur 1 - référencé par x - est horizontal et perpendiculaire à l'axe du véhicule (axe y). When the headlamp is in place on a vehicle, the axis of said reflector 1 - referenced by x - is horizontal and perpendicular to the axis of the vehicle (y-axis).
La source 2 est disposée à l'intérieur du réflecteur 1, au premier foyer F1 de celui-ci. The source 2 is disposed inside the reflector 1, at the first focal point F1 thereof.
La lentille de convergence 3 est disposée en sortie du réflecteur elliptique 1, de façon que son foyer coïncide avec le deuxième foyer F2 dudit réflecteur 1. The convergence lens 3 is disposed at the outlet of the elliptical reflector 1, so that its focal point coincides with the second focal point F2 of said reflector 1.
Le projecteur comporte également un cache de coupure 5 qui s'étend perpendiculairement à l'axe du réflecteur elliptique 1, dans un plan passant par le deuxième foyer F2 dudit réflecteur 1. The projector also includes a cut-off cover 5 which extends perpendicular to the axis of the elliptical reflector 1, in a plane passing through the second focal point F2 of said reflector 1.
Le miroir 4 est disposé sur le trajet optique du faisceau en sortie de la lentille 3. The mirror 4 is placed on the optical path of the beam at the outlet of the lens 3.
I1 est monté pivotant par rapport à un axe z qui passe par sa surface de réflexion et qui est perpendiculaire à la fois à l'axe du réflecteur elliptique 1 et à la direction des faisceaux en sortie du projecteur. I1 is pivotally mounted with respect to an axis z which passes through its reflection surface and which is perpendicular both to the axis of the elliptical reflector 1 and to the direction of the beams leaving the projector.
Plus précisément, lorsque le projecteur est en place sur un véhicule, l'axe z est vertical.More specifically, when the headlamp is in place on a vehicle, the z axis is vertical.
Un moteur électrique (non représenté) permet d'entraîner ce miroir 4 en rotation autour dudit axe z. An electric motor (not shown) drives this mirror 4 in rotation about said axis z.
Ce moteur est commandé par une unité de gestion (également non représentée), en fonction de l'orientation des roues dudit véhicule. Cette unité est programmée de façon à faire tourner ledit miroir de renvoi 4 pour éclairer les portions de route qui se trouvent devant le véhicule et sur le côté de celui-ci, lorsque le véhicule se déplace sur une trajectoire incurvée. This engine is controlled by a management unit (also not shown), according to the orientation of the wheels of said vehicle. This unit is programmed so as to rotate said deflection mirror 4 to illuminate the portions of road which are in front of the vehicle and on the side thereof, when the vehicle is moving on a curved path.
Ainsi, on dispose d'une structure de projecteurs particulièrement simple qui permet de réaliser une fonction virage avec des débattements de faisceaux pouvant atteindre + 400 ou plus. Thus, there is a particularly simple headlamp structure which makes it possible to perform a turning function with beam deflections of up to +400 or more.
En particulier, on notera, comme l'illustre la figure 1, qu'un débattement d'un angle (l pour le miroir 4 permet un débattement de 2a pour le faisceau réfléchi par ledit miroir. Les amplitudes de mouvement nécessaires pour obtenir un débattement d'au moins 400 sont donc divisés par deux (et il en est de même des coûts et des temps de réponse de la structure, ainsi que des volumes nécessaires au débattement). In particular, it will be noted, as illustrated in FIG. 1, that a deflection of an angle (l for the mirror 4 allows a deflection of 2a for the beam reflected by said mirror. The amplitudes of movement necessary to obtain a deflection at least 400 are therefore halved (and the same is true for the costs and response times of the structure, as well as the volumes required for travel).
Egalement, la structure qui vient d'être décrite est peu onéreuse, puisqu'elle ne nécessite qu'un seul moteur électrique. Also, the structure which has just been described is inexpensive, since it requires only one electric motor.
En outre, la combinaison du réflecteur elliptique 1 et d'un miroir de renvoi 4 lui confère une grande compacité. In addition, the combination of the elliptical reflector 1 and a deflection mirror 4 gives it great compactness.
Le peu d'éléments optiques que cette structure comporte lui assure de bonnes performances photométriques. The few optical elements that this structure comprises ensures good photometric performance.
Bien entendu, le projecteur qui vient d'hêtre décrit peut être utilisé à la fois comme projecteur à fonction virage et comme projecteur à fonction antibrouillard. Of course, the headlight which has just been described can be used both as a headlamp with headlamp function and as a headlamp with fog light function.
