Abstract

The headlamp has between the reflector (100) and the lens (200) a filter (300) that is opaque to visible light and transparent to infra-red light. The filter is displaced between a position where it is clear of the visible light beam from the light source (110) and a position where most of the beam passes through the filter.

La structure générale des projecteurs représentés sur les figures 1 à 9 comprend un réflecteur 100 de genre ellipsoïdal, de foyer interne 110 et de foyer externe 120, une lentille 200 dont le foyer est confondu avec le foyer externe 120 du réflecteur 100, et une source de lumière 105 placée sur le foyer interne 110 du réflecteur 100.The general structure of the projectors represented in FIGS. 1 to 9 comprises a reflector 100 of ellipsoidal type, of internal focal point 110 and of external focus 120, a lens 200 whose focus coincides with the external focus 120 of the reflector 100, and a light source 105 placed on the internal focus 110 of the reflector 100.

Les surfaces de genre ellipsoïdal sont habituellement des surfaces définies mathématiquement respectivement à partir de deux zones focales que l'on appelle ici les foyers 110 et 120, mais qui présentent en pratique une légère étendue. Cette étendue englobe le filament de la source dans le cas de la zone focale interne 105, et forme une tâche de lumière dans le cas de la zone focale externe 120. La surface définie mathématiquement se rapproche donc sensiblement d'un ellipsoïde.Ellipsoidal-like surfaces are usually surfaces defined mathematically respectively from two focal areas which we call here hearths 110 and 120, but which present in practice a slight extent. This extent encompasses the filament of the source in the case of the internal focal zone 105, and forms a spot of light in the case of the external focal zone 120. The mathematically defined surface is therefore substantially approximates an ellipsoid.

Les rayons émis par la source, après réflexion sur le réflecteur ellipsoïdal 100 se croisent au voisinage du foyer externe 120. Les rayons lumineux arrivant sur la lentille 200 semblent donc émis par une source de petites dimensions placée sur le foyer 120. Les rayons sont alors projetés en avant du véhicule en formant un faisceau de répartition lumineuse appropriée convenant pour la fonction « route ».The rays emitted by the source, after reflection on the reflector ellipsoidal 100 cross in the vicinity of the external focus 120. The rays light arriving on the lens 200 therefore seem to be emitted by a source of small dimensions placed on the hearth 120. The rays are then projected in front of the vehicle by forming a light distribution beam suitable suitable for the "road" function.

Comme on le voit sur les figures 1 à 9, un filtre mobile de faibles dimensions 300 est en position active, positionné au voisinage du foyer externe 120 du réflecteur 100, de telle sorte qu'il intercepte le rayonnement lumineux quasiment dans son ensemble, du fait de la concentration des rayons à cet endroit.As seen in Figures 1 to 9, a mobile filter of weak dimensions 300 is in the active position, positioned near the hearth external 120 of reflector 100, so that it intercepts radiation bright almost as a whole, due to the concentration of spokes there.

Le filtre 300, ici placé en aval du foyer externe 120, pourra être disposé en amont ou exactement sur le foyer externe 120 par rapport au trajet des rayons lumineux.The filter 300, here placed downstream of the external focus 120, can be arranged upstream or exactly on the external hearth 120 relative to the path of light rays.

Le filtre 300 ainsi placé intercepte presque toute la lumière qui se propage du réflecteur 100 à la lentille 200, tout en étant placé dans une zone de large volume par rapport à la taille du filtre. On peut ainsi placer aisément des moyens de maintien et de déplacement perfectionnés dans cette zone.The filter 300 thus placed intercepts almost all the light which is propagates from the reflector 100 to the lens 200, while being placed in a large volume area in relation to the size of the filter. We can thus place easily improved means of holding and moving in this zone.

Compte tenu de la géométrie générale du projecteur, le positionnement du filtre au voisinage du foyer externe 120 autorise en outre des positions du filtre 300 qui sont voisines de la position active et qui n'interfèrent avec aucun rayonnement, pouvant de ce fait être adoptées comme position inactive du filtre 300.Given the general geometry of the projector, the positioning the filter in the vicinity of the external hearth 120 also allows positions of the filter 300 which are close to the active position and which do not interfere with any radiation, therefore being able to be adopted as inactive position of filter 300.

Le filtre 300 est ici formé par une petite plaque de forme carrée. Il est placé perpendiculairement à l'axe principal de projection.The filter 300 is here formed by a small square plate. It is placed perpendicular to the main projection axis.

Un premier mode de réalisation de ce dispositif est illustré sur les figures 1 et 2, où le filtre 300 est mobile selon une translation verticale de direction y. Dans ce mode de réalisation, le filtre 300 peut être guidé sur un rail 400 symbolisé sur la figure par un axe à trait interrompu et peut être entraíné par exemple par un moteur électrique ou un électro-aimant.A first embodiment of this device is illustrated on the Figures 1 and 2, where the filter 300 is movable in a vertical translation of direction y. In this embodiment, the filter 300 can be guided on a rail 400 symbolized in the figure by an axis with broken lines and can be driven for example by an electric motor or an electromagnet.

Le filtre 300 est préférentiellement logé dans un cadre réalisé en un matériau souple, par exemple en tôle, ce cadre se déformant sous l'effet des dilatations du filtre, sans briser le filtre. Selon une variante, on maintient le filtre 300 à l'aide de moyens élastiques de rappel qui s'étendent ou se plient sous l'effet des dilatations du filtre 300.The filter 300 is preferably housed in a frame made of flexible material, for example sheet metal, this frame deforms under the effect filter expansions, without breaking the filter. According to a variant, one maintains the filter 300 by means of elastic return means which extend or extend bend under the effect of the expansion of the filter 300.

Selon une variante indiquée sur la figure 3, la translation du filtre peut se faire dans une direction Z horizontale, également transversale à la direction principale de propagation.According to a variant indicated in FIG. 3, the translation of the filter can be done in a horizontal Z direction, also transverse to the main direction of propagation.

Sur la figure 4, le filtre 300 est monté à translation sur un rail parallèle à la direction principale de propagation. In FIG. 4, the filter 300 is mounted in translation on a rail parallel to the main direction of propagation.

En position effacée, le filtre 300 se trouve suffisamment distant en avant du foyer externe 120, pour n'interférer qu'avec très peu de lumière.In the erased position, the filter 300 is sufficiently distant in front of the external fireplace 120, so as to interfere with very little light.

En effet, les projecteurs elliptiques présentent typiquement un cône d'ombre 150 correspondant au trou de fond du réflecteur dans lequel est maintenue la lampe. Ce trou, occupé donc par la base de la lampe, ensemble non réfléchissant, est la cause d'une quasi absence de rayon lumineux dans ce cône qui entoure typiquement l'axe principal de propagation.Indeed, elliptical projectors typically have a cone shadow 150 corresponding to the bottom hole of the reflector in which is held the lamp. This hole, therefore occupied by the base of the lamp, non-reflective assembly, is the cause of an almost absence of radius luminous in this cone which typically surrounds the main axis of spread.

Ce cône 150 a généralement une faible ouverture angulaire. Toutefois les dimensions du filtre 300 ainsi disposé étant particulièrement faibles, on loge le filtre 300 dans sa quasi totalité à l'intérieur de ce cône 150 en déplaçant simplement le filtre vers la direction d'ouverture du cône 150.This cone 150 generally has a small angular opening. However, the dimensions of the filter 300 thus disposed being particularly weak, the filter 300 is housed almost entirely inside this cone 150 by simply moving the filter towards the opening direction of the cone 150.

Dans un autre mode de réalisation illustré sur les figures 5 et 6, le filtre 100 est mobile en rotation autour d'un axe horizontal.In another embodiment illustrated in FIGS. 5 and 6, the filter 100 is movable in rotation about a horizontal axis.

A la figure 5, l'axe de rotation est parallèle à la direction principale de propagation de la lumière.In FIG. 5, the axis of rotation is parallel to the main direction of propagation of light.

A la figure 6, l'axe y1 est transversal à la direction de propagation de la lumière au-dessus du flux de lumière.In FIG. 6, the axis y1 is transverse to the direction of propagation of light above the light flow.

L'axe de rotation y1 longe simplement une bordure du filtre de sorte que celui-ci s'efface sur le côté du rayonnement, particulièrement concentré au voisinage du foyer 120.The axis of rotation y1 simply runs along a border of the filter so that it disappears on the side of the radiation, particularly concentrated in the vicinity of foyer 120.

A la figure 7, l'axe de rotation y2 est placé horizontal et en avant de la position active du filtre.In FIG. 7, the axis of rotation y2 is placed horizontal and in front of the active position of the filter.

Sur la figure 7, on a représenté le trajet de la lumière entre le second foyer 120 et la lentille 200. La lumière décrit à cet endroit un cône 250 dont la pointe est sur le second foyer 120, et la base sur la périphérie de la lentille 200. L'axe y2 est placé suffisamment en avant de la position active du filtre 300 pour qu'une rotation d'environ 60° suffise à faire sortir le filtre 300 du cône de lumière 250.In FIG. 7, the path of light between the second is shown. focal point 120 and lens 200. The light describes a cone 250 at this point, the point is on the second focus 120, and the base on the periphery of the lens 200. The axis y2 is placed sufficiently in front of the active position filter 300 so that a rotation of about 60 ° is enough to remove the filter 300 of the cone of light 250.

Plus précisément, l'axe y2 est toutefois suffisamment proche du filtre 300 pour que le filtre 300 vienne border de près le cône 250, parallèlement à son enveloppe conique. More precisely, the axis y2 is however sufficiently close to the filter 300 so that the filter 300 comes close to the cone 250, parallel to its conical envelope.

Plus généralement , un tel mouvement d'escamotage amenant le filtre en bordure directe du flux de lumière interne s'avère à la fois très efficace en termes d'optique, et particulièrement satisfaisant en termes d'encombrement car la bordure directe du cône de lumière s'avère être une zone de rangement très avantageuse pour le filtre 300, car d'étendue et d'épaisseur très bien adaptées.More generally, such a retraction movement bringing the filter at the direct edge of the internal light flow is both very efficient in terms of optics, and particularly satisfactory in terms because the direct border of the light cone turns out to be a very advantageous storage area for the filter 300, because of the extent and very well adapted thickness.

A la figure 8, l'axe de rotation y3 est placé vertical et déporté vers l'avant de la position active du filtre. Les moyens de déplacement du filtre provoquent une rotation de 180° de ce dernier, de sorte que le filtre, lorsque escamoté, subit non seulement une rotation, mais également un décalage vers l'avant, jusqu'à venir se placer dans le cône d'ombre 150 précédemment cité.In FIG. 8, the axis of rotation y3 is placed vertical and offset towards the front of the active filter position. The means of moving the filter cause the latter to rotate 180 °, so that the filter, when retracted, undergoes not only a rotation, but also a shift forward, until it is placed in the shadow cone 150 previously cited.

L'axe y3 et par exemple placé transversalement au centre du rayonnement, à l'intersection avec l'axe principal de rayonnement du projecteur. Ainsi, entre les positions active et inactive, le filtre semble simplement avoir été translaté.The axis y3 and for example placed transversely at the center of the radiation, at the intersection with the main axis of radiation of the projector. Thus, between the active and inactive positions, the filter seems simply have been translated.

Bien entendu, l'invention s'étend à tout type de mouvement du filtre, c'est à dire utilisant tout degré de liberté, par exemple une rotation selon l'un quelconque de trois axes de rotation principaux et/ou une translation selon l'un quelconque de ces trois axes.Of course, the invention extends to any type of movement of the filter, ie using any degree of freedom, for example a rotation according to any one of three main axes of rotation and / or a translation according to any one of these three axes.

A la figure 9, on a représenté un filtre 300 placé légèrement en aval de la zone focale externe 120.In Figure 9, there is shown a filter 300 placed slightly downstream of the external focal area 120.

Dans ce montage, le filtre 300 présente une étendue et un positionnement tel qu'il n'intercepte pas la totalité de la lumière. Une partie des rayons rejoint la lentille 200 en passant à l'extérieur des bords du filtre 300. Ces rayons rejoignent la lentille 200 au niveau de la périphérie de celle-ci.In this arrangement, the filter 300 has a range and a positioning such that it does not intercept all of the light. A part rays join the lens 200 passing outside the edges of the filter 300. These rays join the lens 200 at the periphery of this one.

On utilise ces rayons pour produire à l'avant du véhicule un léger éclairage en lumière visible (lumière ordinaire) qui noie une éventuelle lueur parasite rouge due à la présence du filtre 300.We use these spokes to produce a slight lighting in visible light (ordinary light) which drowns a possible red parasitic glow due to the presence of the filter 300.

Pour accentuer la visibilité de la lueur blanche ainsi formée dans la zone périphérique de la lentille, sans éblouir les conducteurs opposés, on adopte dans cette zone périphérique annulaire de la lentille 300 un aménagement propre à accentuer la diffusion de la lumière, c'est à dire à désorganiser les rayons (effet lanterne).To enhance the visibility of the white glow thus formed in the peripheral zone of the lens, without dazzling the opposite conductors, adopts in this annular peripheral zone of the lens 300 a suitable arrangement to accentuate the diffusion of light, that is to say disorganize the shelves (lantern effect).

La lentille présente par exemple dans cette zone un verre dépoli ou un grainage léger. Ainsi la diffusion des fuites blanches à la périphérie de la lentille produit une photométrie latérale de type « lanterne » qui fournit un aspect blanc à des projecteurs, avec toutefois préférentiellement une forte intensité dans l'axe pour permettre une signalisation soutenue voisine du maximum autorisé pour une lanterne (60 candela) ou de type « Day Running Light » (Signalisation de Jour).The lens for example has in this area a frosted glass or light graining. Thus the diffusion of white leaks on the periphery of the lens produces a side lantern type photometry which provides a white aspect to spotlights, however preferably with a strong intensity in the axis to allow a sustained signaling close to the maximum authorized for a lantern (60 candela) or of the “Day” type Running Light ”.

Plus généralement, on adopte préférentiellement de telles dispositions dans lesquelles on ménage une fuite organisée de lumière blanche hors du filtre, et on diffuse préférentiellement ces fuites en sortie du projecteur.More generally, we preferentially adopt such arrangements in which an organized light leak is managed white outside the filter, and these leaks are preferentially diffused at the outlet of the projector.

On évite ainsi d'utiliser une lanterne blanche constituée par une seconde source.This avoids using a white lantern consisting of a second source.
