Description
La présente invention concerne le domaine de l’éclairage et/ou de la signalisation et les organes, notamment optiques, qui y participent. Elle trouve pour application particulièrement avantageuse le domaine des véhicules automobiles. Notamment, elle est relative à un module lumineux pour véhicule automobile, et à un dispositif d’éclairage et/ou de signalisation muni d’un tel module.The present invention relates to the field of lighting and/or signaling and the organs, in particular optical, which participate therein. It finds a particularly advantageous application in the field of motor vehicles. In particular, it relates to a light module for a motor vehicle, and to a lighting and/or signaling device equipped with such a module.
ETAT DE LA TECHNIQUESTATE OF THE ART
Dans le secteur de l’automobile, on connaît des dispositifs susceptibles d’émettre des faisceaux lumineux, encore appelés fonctions d’éclairage et/ou de signalisation, répondant en général à des réglementations.In the automobile sector, devices capable of emitting light beams, also called lighting and/or signaling functions, are known, generally complying with regulations.
Récemment, on a développé des technologies permettant de produire un faisceau segmenté, aussi appelé pixélisé, pour réaliser des fonctions d’éclairage avancées. C’est notamment le cas pour une fonction d’éclairage de type «route complémentaire » généralement basée sur une pluralité d’unités d’illumination comportant chacune une diode électroluminescente, diodes qui peuvent être pilotées individuellement. Ce faisceau peut, notamment, servir à compléter l’éclairage d’un faisceau de type code, pour former globalement un éclairage de type route. Le faisceau segmenté peut également faire partie d’un faisceau d’éclairage de type « code ». En particulier, le faisceau segmenté forme alors par exemple, en mode code, la portion coudée, encore appelée « kink », du faisceau « code ». En outre, le faisceau segmenté garantit la valeur maximale de l’éclairement du faisceau « code » (Emax) à un endroit respectant les réglementations tout en donnant une longue portée au faisceau « code » global. En mode « route », l’ensemble des diodes peut être activé.Recently, technologies have been developed to produce a segmented beam, also called pixelated, to perform advanced lighting functions. This is particularly the case for a lighting function of the "complementary road" type generally based on a plurality of lighting units each comprising a light-emitting diode, diodes which can be controlled individually. This beam can, in particular, be used to complete the lighting of a dipped type beam, to globally form a road type lighting. The segmented beam can also be part of a "dipped" type lighting beam. In particular, the segmented beam then forms, for example, in code mode, the angled portion, also called “kink”, of the “code” beam. In addition, the segmented beam guarantees the maximum value of the dipped beam illuminance (Emax) at a place complying with the regulations while giving a long reach to the overall dipped beam. In "road" mode, all the diodes can be activated.
Le faisceau résultant de différents segments de faisceau issus de chacune des diodes, est projeté au moyen d’un système optique de projection comprenant plusieurs lentilles. Par exemple, on peut produire un faisceau complémentaire, associé à un faisceau de base totalement ou pour le moins majoritairement projeté en dessous d’une ligne horizontale de coupure du type utilisé pour la fonction de feu de croisement, le faisceau complémentaire s’additionnant au faisceau de base de sorte à le compléter au-dessus de la ligne de coupure ; avantageusement, ce faisceau complémentaire est adaptatif pour allumer ou éteindre certaines parties du faisceau global projeté, par exemple pour des fonctions anti-éblouissement. L’acronyme ADB (pour Adaptative Driving Beam signifiant faisceau de route adaptatif) est utilisé pour ce type de fonction.The beam resulting from different beam segments from each of the diodes is projected by means of a projection optical system comprising several lenses. For example, a complementary beam can be produced, associated with a base beam totally or at least mainly projected below a horizontal cut-off line of the type used for the dipped beam function, the complementary beam being added to the base beam so as to complete it above the cut line; advantageously, this complementary beam is adaptive to switch on or off certain parts of the overall projected beam, for example for anti-dazzle functions. The acronym ADB (for Adaptive Driving Beam) is used for this type of function.
Dans la présente description, on appelle faisceau segmenté un faisceau dont la projection forme une image composée de segments de faisceau, chaque segment pouvant être allumé de manière indépendante. On peut employer une source de lumière pixélisée pour former ces segments. Une telle source comprend une pluralité d’éléments émissifs activables sélectivement. Les éléments émissifs sont typiquement placés les uns à côté des autres sur un support, avec un certain pas.In the present description, a segmented beam is a beam whose projection forms an image composed of beam segments, each segment being able to be lit independently. A pixelated light source can be used to form these segments. Such a source comprises a plurality of selectively activatable emissive elements. The emissive elements are typically placed next to each other on a support, with a certain pitch.
La publication brevet FR 3077362 A1 divulgue un module lumineux pour véhicule automobile qui comporte des rangées de sources lumineuses sous forme de diodes électroluminescentes et des moyens optiques permettant de traiter optiquement des rayons issus des diodes pour construire des faisceaux d’éclairage automobile de manière adaptative. Les diodes électroluminescentes possèdent une partie émissive de lumière proprement dite et un boîtier optique entourant la face de sortie de lumière de la partie émissive, ce boîtier réalisant un premier élément optique sur le trajet des rayons. Par construction, les diodes électroluminescentes employées selon cette antériorité sont donc relativement espacées les unes des autres, compte tenu de leur boîtier, ce qui permet assez facilement de procurer un effet volumique au faisceau global. Mais les moyens optiques associés aux diodes, selon une telle solution technique, impliquent malgré tout une complexité importante pour éviter des effets de bord entre les faisceaux unitaires émis par chaque diode ; en effet, sans traitement optique ultérieur, les pixels projetés seraient séparés les uns des autres par des bords sombres du fait du pas significatif de leur implantation sur leur support.Patent publication FR 3077362 A1 discloses a light module for a motor vehicle which comprises rows of light sources in the form of light-emitting diodes and optical means making it possible to optically process the rays coming from the diodes in order to construct automotive lighting beams in an adaptive manner. Light-emitting diodes have a light-emitting part proper and an optical housing surrounding the light-emitting part's exit face, this housing forming a first optical element on the path of the rays. By construction, the light-emitting diodes used according to this prior art are therefore relatively spaced from each other, given their housing, which makes it quite easy to provide a volume effect to the overall beam. But the optical means associated with the diodes, according to such a technical solution, nevertheless involve considerable complexity in order to avoid edge effects between the unit beams emitted by each diode; indeed, without subsequent optical processing, the projected pixels would be separated from each other by dark edges due to the significant pitch of their implantation on their support.
Un objet de la présente invention est notamment de proposer une solution à ce problème, en autorisant une alternative quant à l’association de sources lumineuses et de moyens optiques.An object of the present invention is in particular to propose a solution to this problem, by authorizing an alternative as regards the association of light sources and optical means.
Les autres objets, caractéristiques et avantages de la présente invention apparaîtront à l'examen de la description suivante et des dessins d'accompagnement. Il est entendu que d'autres avantages peuvent être incorporés.The other objects, features and advantages of the present invention will become apparent from a review of the following description and the accompanying drawings. It is understood that other benefits may be incorporated.
RESUMESUMMARY
Pour atteindre cet objectif, selon un mode de réalisation on prévoit un module lumineux pour véhicule automobile, comprenant au moins une première rangée de sources lumineuses configurée pour produire un premier faisceau de sortie, et une deuxième rangée de sources lumineuses configurée pour produire un deuxième faisceau de sortie, caractérisé en ce que les sources lumineuses de la première rangée et de la deuxième rangée sont des diodes électroluminescentes à partie émissive maximisée , et en ce qu’il comprend un élément optique primaire configuré pour recevoir les rayons lumineux des sources de la première rangée et de la deuxième rangée, l’élément optique primaire étant configuré pour produire une réflexion interne des rayons lumineux des sources d’au moins l’une parmi la première rangée et la deuxième rangée.To achieve this objective, according to one embodiment, a light module for a motor vehicle is provided, comprising at least a first row of light sources configured to produce a first output beam, and a second row of light sources configured to produce a second beam output, characterized in that the light sources of the first row and of the second row are light-emitting diodes with a maximized emissive part, and in that it comprises a primary optical element configured to receive the light rays from the sources of the first row and the second row, the primary optical element being configured to produce an internal reflection of the light rays from the sources of at least one of the first row and the second row.
Ainsi, on tire profit de ce type de sources de lumière de sorte à disposer ces sources très proches les unes des autres (typiquement avec un espace de moins de 50 microns, voire de moins de 25 microns). Il est possible de venir imager directement au niveau de ces sources ; cependant, l’efficacité du système optique est maintenue et on opère une mise en forme, notamment verticale, des pixels, par l’intermédiaire de l’élément optique primaire qui est un élément commun aux sources.Thus, advantage is taken of this type of light source so as to arrange these sources very close to each other (typically with a space of less than 50 microns, or even less than 25 microns). It is possible to image directly at these sources; however, the efficiency of the optical system is maintained and shaping, in particular vertical, of the pixels is carried out via the primary optical element which is an element common to the sources.
Suivant une possibilité avantageuse, l’élément optique présente une face d’entrée de rayons lumineux simplifiée, par exemple sans nécessiter le recours à des motifs comme ceux de microlentilles. En outre, un seul élément optique est employé pour plusieurs rangées de sources. De cette manière, on s’affranchit donc des optiques primaires de forme complexe telles que les guides de lumières.According to an advantageous possibility, the optical element has a simplified light ray entry face, for example without requiring the use of patterns such as those of microlenses. Furthermore, a single optical element is used for several rows of sources. In this way, we do away with primary optics of complex shape such as light guides.
De manière facultative, l’élément optique primaire présente une face d’entrée des rayons lumineux et une face de réflexion configurée pour produire la réflexion interne, la face d’entrée et la face de réflexion formant une surface réglée ayant des génératrices parallèles. Cette surface réglée peut aussi inclure au moins une face de sortie de l’élément optique primaire. Une telle surface peut correspondre à une forme obtenue par une extrusion, en particulier une extrusion régulière. Cette modalité peut être appliquée sur au moins l’une parmi la face d’entrée et la face de réflexion. Les indications précédentes peuvent aussi être valables pour la face de sortie.Optionally, the primary optical element has an entry face for the light rays and a reflection face configured to produce the internal reflection, the entry face and the reflection face forming a ruled surface having parallel generatrices. This ruled surface can also include at least one output face of the primary optical element. Such a surface may correspond to a shape obtained by extrusion, in particular regular extrusion. This modality can be applied on at least one of the entrance face and the reflection face. The previous indications can also be valid for the exit face.
Grâce à cette disposition, l’élément optique primaire peut être simplifié, en évitant autant que possible des surfaces complexes. En particulier, la surface réglée forme une portion de volume cylindrique, en ce sens que cette portion est générée par la circulation d’une génératrice perpendiculairement à une ligne porteuse. Dans un exemple de réalisation, la ligne porteuse peut être parallèle à la première rangée de sources lumineuses et/ou à la deuxième rangée de sources lumineuses. Par exemple, la fabrication peut être simplifiée, notamment par des techniques de moulage conventionnelles.Thanks to this arrangement, the primary optical element can be simplified, avoiding complex surfaces as much as possible. In particular, the ruled surface forms a portion of cylindrical volume, in the sense that this portion is generated by the circulation of a generatrix perpendicular to a carrier line. In an exemplary embodiment, the carrier line may be parallel to the first row of light sources and/or to the second row of light sources. For example, the manufacture can be simplified, in particular by conventional molding techniques.
Un autre aspect concerne un dispositif d’éclairage et/ou de signalisation de véhicule automobile équipé d’au moins un module tel que décrit précédemment.Another aspect relates to a motor vehicle lighting and/or signaling device equipped with at least one module as described above.
Un autre aspect est relatif à un véhicule automobile équipé d’au moins un module et/ou un tel dispositif.Another aspect relates to a motor vehicle equipped with at least one module and/or such a device.
