Downstream of the folder, the spokes are projected via a projection lens located at the output of the lighting module.

- the focal region corresponds to the focus F of the lens 10.
- the first collector 5 comprises a reflection surface 55 of the light coming from the second collector 6. More precisely, the beam cutoff profile is produced by a surface element 55 of the first collector 5 at the level of the focus F, this surface element forming a diopter between the first collector 5 and the ambient medium consisting of air.

- the lower surface 67 of the second collector 6 ' is shaped, so that the light from the first collector 5' undergoes a total reflection on this surface.
- the light thus emitted may be used to illuminate road signs located above the roadway, in height.
- the lower surface 67 of the second collector 6 ' is shaped to illuminate the signs, whether in partial or total reflection, or by metallizing this surface.
- the figure 3 shows in section, in a vertical plane (O, Y, Z) passing through the optical axis A, an embodiment variant applied to the first embodiment of the invention described above with reference to the figure 1 .

- the cut is achieved by a total reflection at the level of the dioptric surface.
- This embodiment in which the first and second collectors are both extended to the focal point F of the lens 10, advantageously makes it possible to maximize the optical fluxes respectively from the first 5 and second 6 'collectors, since each of these fluxes undergo a total reflection at the level of the dioptric surface.
- the two collectors are separated by a thin slice of air disposed along the optical axis A, so that that each collector defines a dioptric surface with air.
- Each dioptric surface thus formed by a collector makes it possible to reflect all or part of the light emitted by the other collector. Thus, all or part of the rays coming from the two collectors are reflected towards the upper and lower ends of the lens 10.

- This is the stop of the first manifold 5, 5 "between its outlet surface 53 and its lower surface 55 as illustrated on the figures 1 , 3 or the stop of the second collector 6 ', 6 "between its outlet surface 63 and its lower surface 65 as illustrated in FIGS. figures 2 , 4 .
- the figure 6 shows in perspective, a multi-source module according to the invention comprising several transmission modules according to the second embodiment previously described with reference to the figure 2 .

Description
La présente invention est relative à un dispositif d'émission d'un faisceau lumineux. Une application préférée concerne l'industrie automobile pour la réalisation de dispositifs d'éclairage, notamment de projecteurs de véhicules automobiles.The present invention relates to a device for emitting a light beam. A preferred application relates to the automotive industry for the production of lighting devices, including motor vehicle headlights.
Dans ce domaine, on connaît des modules d'éclairage parmi lesquels on trouve traditionnellement des feux de croisement, ou codes, d'une portée sur la route avoisinant 70 mètres, qui sont utilisés essentiellement la nuit et dont la configuration du faisceau lumineux est telle qu'elle permet de ne pas éblouir le conducteur d'un véhicule croisé ou suivi. Typiquement, ce faisceau présente une coupure en partie supérieure avec une portion horizontale, préférentiellement environ 0,57 degrés en dessous de l'horizon, afin de ne pas éclairer la zone dans laquelle devrait se trouver le conducteur d'un véhicule arrivant en sens inverse.In this field, light modules are known, among which are traditionally found low beam or codes, a range on the road of 70 meters, which are used mainly at night and whose configuration of the light beam is such it does not dazzle the driver of a crossover vehicle or tracking. Typically, this beam has a cut in the upper part with a horizontal portion, preferably about 0.57 degrees below the horizon, so as not to illuminate the area in which should be the driver of a vehicle coming in the opposite direction .
La publication
Cette antériorité a une structure relativement complexe notamment en raison d'un nombre élevé de pièces à assembler pour former le projecteur. Par ailleurs, la plieuse disposée entre les deux collecteurs a pour effet de générer une ligne sombre dans le faisceau de lumière, lorsque les première et deuxième sources de lumière sont allumées pour un éclairage « plein phares » (feux de route).This prior art has a relatively complex structure in particular because of a large number of parts to be assembled to form the projector. Furthermore, the folder disposed between the two collectors has the effect of generating a dark line in the light beam, when the first and second light sources are turned on for a "full beam" lighting (high beams).
L'invention permet de résoudre tout ou partie des inconvénients des techniques actuelles et propose, à cette fin, de mettre en oeuvre la fonction de coupure en exploitant le phénomène de réflexion, de préférence totale, sur l'un des collecteurs, de manière à s'affranchir de la plieuse. Dans la description qui va suivre, on entend par « collecteur adapté pour réfléchir un rayon lumineux par réflexion totale » un collecteur réalisé en un matériau d'indice de réfraction tel qu'un rayon lumineux, arrivant sur une paroi du collecteur avec un angle d'incidence supérieure à une valeur prédéterminée, est totalement réfléchi sur cette paroi, sans qu'une partie de l'énergie de ce rayon soit sensiblement transmise au travers de cette paroi.The invention makes it possible to solve all or part of the drawbacks of current techniques and proposes, for this purpose, to implement the cut-off function by exploiting the reflection phenomenon, preferably total, on one of the collectors, so as to get rid of the folder. In the following description, the term "collector adapted to reflect a light ray by total reflection" means a collector made of a refractive index material such as a light beam, arriving on a wall of the collector with an angle of incidence greater than a predetermined value, is totally reflected on this wall, without a part of the energy of this ray is substantially transmitted through this wall.
L'invention concerne, en ce sens, un module d'émission d'au moins un faisceau lumineux suivant un axe optique, avec un profil de coupure pour véhicule automobile, le module comprenant des au moins une première et au moins une deuxième sources lumineuses et des au moins un premier et au moins un deuxième collecteurs optiques adaptés à collecter une lumière émise par lesdites au moins une première et au moins une deuxième sources lumineuses respectivement et à rediriger ladite lumière vers une région focale.The invention relates, in this sense, to a module for emitting at least one light beam along an optical axis, with a cut-off profile for a motor vehicle, the module comprising at least a first and at least a second light source. and at least first and at least second optical collectors adapted to collect light emitted by said at least first and at least second light sources respectively and to redirect said light to a focal region.
Selon l'invention, l'un desdits au moins un premier et/ou au moins un deuxième collecteurs est avantageusement utilisé en tant que réflecteur optique pour générer un faisceau avec un profil de coupure, sans nécessiter de composant additionnel, tel qu'une plaque métallique fixée entre lesdits premier et deuxième collecteurs. Ledit collecteur jouant le rôle d'élément de coupure, permet de réfléchir tout ou une partie des rayons issus du ou des autres collecteur(s), vers une extrémité supérieure/inférieure de la lentille, éventuellement prévue pour projeter le faisceau.According to the invention, one of said at least one first and / or at least one second collector is advantageously used as an optical reflector for generating a beam with a cutoff profile, without the need for an additional component, such as a plate metal bonded between said first and second collectors. Said collector acting as a cut-off element makes it possible to reflect all or part of the rays coming from the other collector (s) towards an upper / lower end of the lens, possibly designed to project the beam.
Selon divers modes de réalisation envisagés, la réflexion peut être réalisée, soit par réflexion vitreuse sur une surface dioptrique définie entre le collecteur et le milieu ambient, soit par réflexion métallique sur un revêtement métallique déposé sur une partie de la surface du collecteur. Dans les deux cas, la surface externe d'un collecteur par rapport à l'autre, joue le rôle de réflecteur optique.According to various embodiments envisaged, the reflection can be carried out either by glassy reflection on a dioptric surface defined between the collector and the ambient medium, or by metallic reflection on a metal coating deposited on a part of the surface of the collector. In both cases, the outer surface of one manifold relative to the other acts as an optical reflector.
De manière avantageuse, l'un au moins desdits collecteurs s'étend en direction de la région focale pour réfléchir une partie de la lumière émise par l'autre collecteur, de façon à définir le profil de coupure.Advantageously, at least one of said collectors extends towards the focal region to reflect a portion of the light emitted by the other collector, so as to define the cutoff profile.

Le module d'éclairage illustré à la
Le module d'éclairage (ou module d'émission) selon l'invention 1 comprend un premier ensemble constitué d'une première source lumineuse 3 et d'un premier collecteur optique 5, le premier ensemble optique étant destiné à fournir un premier faisceau lumineux.The lighting module (or transmission module) according to the invention 1 comprises a first set consisting of a first
Le module 1 selon l'invention comprend, en outre, un deuxième ensemble constitué d'une deuxième source lumineuse 4 et d'un deuxième collecteur optique 6, le deuxième ensemble optique étant destiné à fournir un deuxième faisceau lumineux.The module 1 according to the invention further comprises a second assembly consisting of a second
Une lentille convergente 10 est disposée le long de l'axe optique A, de manière à projeter les faisceaux optiques issus des collecteurs et à réaliser l'un des deux modes d'éclairage prévus en fonction de l'allumage de l'une ou des deux sources lumineuses 3, 4.A
Selon l'invention, le premier collecteur 5 s'étend en direction d'une région focale pour réfléchir une partie de la lumière émise par l'autre collecteur, de façon à définir le profil de coupure. Dans le cas présent, la région focale correspond au foyer F de la lentille 10.According to the invention, the
De manière avantageuse, le premier collecteur 5 comprend une surface de réflexion 55 de la lumière issue du deuxième collecteur 6. Plus précisément, le profil de coupure du faisceau est produit par un élément de surface 55 du premier collecteur 5 au niveau du foyer F, cet élément de surface formant un dioptre entre le premier collecteur 5 et le milieu ambiant constitué d'air. La coupure est mise en oeuvre par une réflexion partielle externe de type réflexion vitreuse. Ainsi, une coupure du faisceau peut être réalisée de manière avantageuse sans nécessiter de composant additionnel, tel qu'une plaque métallique dite plieuse (ou folder en anglais).Advantageously, the
Les coupures produites peuvent avoir toute orientation dans l'espace. Le profil de coupure s'entend préférentiellement de la formation d'un faisceau de sortie, non uniformément réparti autour de l'axe optique, du fait de la présence d'une zone de moindre exposition lumineuse, cette zone étant sensiblement délimitée par un profil de coupure, qui peut être formé par au moins deux, et notamment trois segments de droite formant un angle entre eux pour former un virage, connu sous le vocable anglais « kink ». L'éclairage résultant est dit de type « feux de codes ».The cuts produced can have any orientation in the space. The cutoff profile preferably refers to the formation of an output beam, not uniformly distributed around the optical axis, due to the presence of a zone of least light exposure, this zone being substantially delimited by a profile. cut, which can be formed by at least two, and in particular three line segments forming an angle between them to form a turn, known as "kink". The resulting lighting is called "code lights".
Dans l'exemple présent, chaque source lumineuse 3, 4 est constituée d'une diode électroluminescente. Toutefois, dans d'autres modes de réalisation, plusieurs éléments d'émission pourront être combinés pour former chacune des première et deuxième sources lumineuses, de manière à émettre un flux lumineux de puissance optique plus élevée en sortie de la lentille de projection. Chaque élément d'émission pourra être constitué, par exemple, par une diode électroluminescente ou une diode laser.In the present example, each
Selon une autre particularité de l'invention, les première 3 et deuxième 4 sources lumineuses sont orientées, de manière à émettre de la lumière selon des directions parallèles à l'axe optique A du module.According to another particularity of the invention, the first 3 and second 4 light sources are oriented, so as to emit light in directions parallel to the optical axis A of the module.
Les premier 5 et deuxième 6 collecteurs sont adaptés pour collecter la lumière émise par les première 3 et deuxième 4 sources lumineuses respectivement et pour rediriger la lumière collectée vers la région focale et en particulier vers le point focal F.The first 5 and second 6 collectors are adapted to collect the light emitted by the first 3 and second 4 light sources respectively and to redirect the collected light to the focal region and in particular to the focal point F.
Selon une particularité de l'invention, le premier collecteur 5 s'étendant en direction de la région focale comprend une région de collecte 51 présentant un axe de symétrie incliné en direction de l'axe optique A du module.According to a feature of the invention, the
Selon une autre particularité de l'invention, les premier et deuxième collecteurs sont séparés par un milieu d'indice de réfraction inférieur à l'indice de réfraction des collecteurs. Dans le présent exemple, ce milieu est constitué d'air.According to another particularity of the invention, the first and second collectors are separated by a medium of refractive index lower than the index of refraction of the collectors. In the present example, this medium consists of air.
Comme déjà indiqué, une surface dioptrique 55 est ainsi formée entre l'air et le premier collecteur 5. De la sorte, tout ou partie des rayons issus du deuxième collecteur 6 se réfléchissent à la surface du premier collecteur 5, par exemple, selon une réflexion vitreuse.As already indicated, a
Selon une autre particularité de l'invention, le premier collecteur 5 s'étendant en direction de la région focale présente une face de sortie 53 comprise dans la région focale et plus particulièrement dans un plan vertical (F, O, Y) comprenant le point focal F. La surface dioptrique 55 du premier collecteur 5 est tangente à l'axe optique A du module.According to another feature of the invention, the
Les premier et deuxième collecteurs sont constitués d'un matériau transparent ayant un indice de réfraction supérieur à l'indice de réfraction de l'air. On utilisera préférentiellement du polycarbonate (PC) adapté à résister à la chaleur générée par les diodes (LED). Le choix de ce matériau est particulièrement avantageux, dans la mesure où les diodes LED se trouvent à proximité des collecteurs transparents.The first and second collectors are made of a transparent material having a refractive index greater than the refractive index of air. Preferably polycarbonate (PC) adapted to resist the heat generated by the diodes (LED) will be used. The choice of this material is particularly advantageous insofar as the LEDs are near the transparent collectors.
Dans d'autres exemples de réalisation, les collecteurs pourront être constitués en carbonate de polypropylène (PPC) ou en polyméthacrylate de méthyle (PMMA).In other exemplary embodiments, the collectors may be made of polypropylene carbonate (PPC) or polymethyl methacrylate (PMMA).

Selon une particularité de l'invention, le deuxième collecteur 6' s'étendant en direction de la région focale, comprend une région de collecte 61 présentant un axe de symétrie incliné en direction de l'axe optique A du module.According to a feature of the invention, the second collector 6 'extending towards the focal region comprises a
Une surface dioptrique 65 est formée entre le milieu ambiant constitué d'air et le deuxième collecteur 6', permettant à tout ou partie des rayons issus du premier collecteur 5' de se réfléchir à la surface du deuxième collecteur 6' par une réflexion partielle externe de type réflexion vitreuse. Le profil de coupure du faisceau est produit par un élément de la surface dioptrique 65 au niveau du foyer F, comme décrit précédemment en référence à la
La première source lumineuse 3 et/ou le premier collecteur 5' sont adaptés, de sorte qu'une partie de la lumière issue de cette source traverse le premier collecteur 5' et pénètre dans le deuxième collecteur 6'. A cet effet, plusieurs adaptations peuvent être envisagées :
- a) la première source lumineuse 3 est légèrement inclinée en direction de l'axe optique A ; et/ou
- b) la première source lumineuse 3 émet selon un angle d'émission suffisamment large en direction du deuxième collecteur 6' ; et/ou
- c) la zone de collecte du premier collecteur 5' est conformée de sorte qu'une partie des rayons émis par la première
source 3 ne soient pas réfléchis à la surface du premier collecteur 5', de manière à ce que ces rayons soient injectés dans le deuxième collecteur 6'.
- a) the first
light source 3 is slightly inclined towards the optical axis A; and or - b) the first
light source 3 emits at a sufficiently wide emission angle towards the second collector 6 '; and or - c) the collection zone of the first collector 5 'is shaped so that part of the rays emitted by the
first source 3 are not reflected on the surface of the first collector 5', so that these rays are injected into the second collector 6 '.
Le deuxième collecteur 6' est adapté pour guider la lumière injectée en provenance du premier collecteur 5', jusqu'à la surface de sortie 63 du deuxième collecteur 6', de manière à atteindre la lentille de projection 10. Pour cela, la surface inférieure 67 du deuxième collecteur 6' est conformée, de telle sorte que la lumière issue du premier collecteur 5' subisse une réflexion totale sur cette surface. La lumière ainsi émise pourra servir à éclairer des panneaux de signalisation situés au-dessus de la chaussée, en hauteur.The second collector 6 'is adapted to guide the injected light from the first collector 5', to the
La surface inférieure 67 du deuxième collecteur 6' est conformée pour éclairer les panneaux de signalisation, que ce soit en réflexion partielle ou totale, ou en métallisant cette surface.The

Selon cette variante de réalisation, le premier collecteur 5" s'étendant vers la région focale, comprend un revêtement réfléchissant 8 disposé sur une partie du collecteur 5" notamment au niveau de la région focale, de manière à réfléchir tout ou partie des rayons issus de l'autre collecteur 6 selon un profil de coupure. A titre d'exemple illustratif et non limitatif, ce revêtement réfléchissant 8 est constitué par une fine couche de métal, la couche étant suffisamment fine pour éviter l'apparition d'une zone d'absence de lumière, en sortie de la lentille de projection 10. Ce revêtement métallique permet en outre d'améliorer l'efficacité d'émission de la partie du module qui ne s'étend pas jusqu'à la région focale (i.e. deuxième source 4 et deuxième collecteur 6 dans l'exemple de la
Selon cette variante de réalisation, le revêtement métallique 8 recouvre en partie la surface 55 du premier collecteur 5 tangente à l'axe optique A, de sorte que tout ou partie des rayons issus du deuxième collecteur 6 se réfléchissent sur le revêtement métallique 8 (réflexion externe de type réflexion métallique), de manière à être redirigés vers une extrémité inférieure de la lentille 10.According to this variant embodiment, the metal coating 8 partially covers the
La
Selon cette même variante de réalisation, le revêtement métallique 8' recouvre en partie la surface 65 du deuxième collecteur 6" tangente à l'axe optique A, de sorte que tout ou partie des rayons issus du premier collecteur 5' se réfléchissent sur la couche métallique 8', de manière à être redirigés vers une extrémité supérieure de la lentille 10.According to this same variant embodiment, the metal coating 8 'partially covers the
Ainsi, la coupure du faisceau est réalisée au moyen d'une réflexion métallique des rayons issus du premier collecteur 5' mise en oeuvre par le revêtement métallique 8'.Thus, the cutting of the beam is carried out by means of a metallic reflection of the rays coming from the first collector 5 'implemented by the metal coating 8'.
La
Selon une particularité de l'invention, les deux collecteurs 5, 6' présentent chacun une face de sortie 53, 63 comprise dans la région focale, et en particulier dans un plan vertical (F, Y, Z) comprenant le point focal F de la lentille 10.According to a feature of the invention, the two
Comme illustré à la
Ainsi, la coupure est réalisée par une réflexion totale au niveau de la surface dioptrique.Thus, the cut is achieved by a total reflection at the level of the dioptric surface.
Ce mode de réalisation, dans lequel les premier et deuxième collecteurs sont tous deux étendus jusqu'au point focal F de la lentille 10, permet avantageusement de maximiser les flux optiques issus respectivement des premier 5 et deuxième 6' collecteurs, étant donné que chacun de ces flux subit une réflexion totale au niveau de la surface dioptrique.This embodiment, in which the first and second collectors are both extended to the focal point F of the
Selon une autre particularité de l'invention, prévue en particulier dans le cas où les deux collecteurs présentent un même indice de réfraction, les deux collecteurs sont séparés par une fine tranche d'air disposée le long de l'axe optique A, de sorte que chaque collecteur définisse une surface dioptrique avec l'air.According to another particularity of the invention, provided in particular in the case where the two collectors have the same refractive index, the two collectors are separated by a thin slice of air disposed along the optical axis A, so that that each collector defines a dioptric surface with air.
Chaque surface dioptrique ainsi formée par un collecteur permet de réfléchir tout ou une partie de la lumière émise par l'autre collecteur. Ainsi, tout ou partie des rayons issus des deux collecteurs sont réfléchis vers des extrémités supérieure et inférieure de la lentille 10.Each dioptric surface thus formed by a collector makes it possible to reflect all or part of the light emitted by the other collector. Thus, all or part of the rays coming from the two collectors are reflected towards the upper and lower ends of the
Dans les modes de réalisation décrits en référence aux
Dans d'autres modes de réalisation de l'invention, cette face de sortie pourra présenter une surface bombée ou creusée et/ou pourra être inclinée par rapport à l'axe optique, afin d'élargir ou de concentrer le faisceau optique et/ou de corriger d'éventuelles aberrations de la lentille de projection 10.In other embodiments of the invention, this exit face may have a convex or sunken surface and / or may be inclined with respect to the optical axis, in order to enlarge or focus the optical beam and / or to correct any aberrations of the
L'arrête formée par l'intersection de la surface de sortie du collecteur transparent ayant été étendu en direction de l'axe optique et de la surface inférieure de ce collecteur, formant l'élément de coupure, peut être conformée de manière à réduire l'effet des aberrations de la lentille de projection 10 sur la forme de la coupure dans le faisceau. Il s'agit de l'arrête du premier collecteur 5, 5"entre sa surface de sortie 53 et sa surface inférieure 55 comme illustrée sur les

Le module est dit « multi-sources » dans le sens où il comprend plusieurs sources lumineuses pour disposer d'une puissance optique suffisante, conformément aux normes d'éclairage en vigueur. En particulier, le module comprend une première rangée de sept diodes électroluminescentes 3a, 3b , 3c, 3d, 3e, 3f, 3g (premières sources) et une deuxième rangée de cinq diodes électroluminescentes 4c, 4d, 4e, 4f, 4g (deuxièmes sources). Sept premiers collecteurs et cinq deuxièmes collecteurs sont associés respectivement aux sept premières et cinq deuxièmes sources lumineuses.The module is called "multi-source" in the sense that it includes several light sources to have sufficient optical power, in accordance with current lighting standards. In particular, the module comprises a first row of seven light-emitting
Selon une particularité de l'invention, les deuxièmes collecteurs sont en continuité de matière les uns avec les autres, de manière à former une seule pièce 600, cette pièce pouvant être facilement réalisée par moulage ou par toute autre technique de fabrication adaptée. Dans d'autres exemples de réalisation, les premiers collecteurs sont en continuité de matière les uns avec les autres, de manière à former une seule pièce.According to a feature of the invention, the second collectors are in continuity of material with each other, so as to form a single piece 600, this part can be easily made by molding or by any other suitable manufacturing technique. In other exemplary embodiments, the first collectors are in continuity of material with each other, so as to form a single piece.
Le module comprend en outre une lentille de projection 100 commune à l'ensemble des sources et des collecteurs.The module further comprises a
