DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTION TECHNICAL FIELD TO WHICH THE INVENTION REFERS
[01] La présente invention concerne le domaine technique de l'éclairage et/ou de la signalisation lumineuse. Elle concerne plus particulièrement un dispositif lumineux et/ou de signalisation pour véhicule automobile. [01] The present invention relates to the technical field of lighting and / or light signaling. It relates more particularly to a light and / or signaling device for a motor vehicle.
ARRIERE-PLAN TECHNOLOGIQUE BACKGROUND
[02] Les normes réglementaires imposent à chaque véhicule automobile d’être équipé de dispositifs lumineux afin d’avertir les usagers de la route de la présence et des intentions des autres conducteurs. On peut notamment citer les feux de position, situés à l’arrière du véhicule, de couleur rouge et d’intensité modérée pour signaler sa position, et les feux-stops également de couleur rouge, mais d’intensité plus forte pour avertir du freinage du véhicule automobile. [02] The regulatory standards require each motor vehicle to be equipped with lighting devices in order to warn road users of the presence and intentions of other drivers. These include the position lights, located at the rear of the vehicle, of red color and moderate intensity to signal its position, and stop lights also red, but stronger intensity to warn of braking of the motor vehicle.
[03] Ces dispositifs lumineux comportent des surfaces réfléchissantes permettant de diriger vers l’extérieur et selon une direction souhaitée, le faisceau lumineux émis par une source de lumière. Les surfaces métallisées sont privilégiées en raison de leur fort coefficient de réflexion, comme le chrome ou l’aluminium. À la lumière du jour, ces surfaces métallisées se caractérisent par une couleur de ton clair, ce qui peut engendrer un contraste non souhaité avec la couleur de la carrosserie. C’est notamment le cas lorsque la carrosserie est peinte d’une couleur dont le ton est sombre, modifiant localement et de façon prononcée l’aspect esthétique du véhicule à la lumière du jour. [03] These luminous devices have reflective surfaces for directing outwards and in a desired direction, the light beam emitted by a light source. Metallized surfaces are favored because of their high coefficient of reflection, such as chromium or aluminum. In daylight, these metallic surfaces are characterized by a light tone color, which can create unwanted contrast with the color of the bodywork. This is particularly the case when the bodywork is painted with a color whose tone is dark, locally modifying and pronounced the aesthetic appearance of the vehicle in the light of day.
[04] La présente invention vise à résoudre cette problématique en proposant un dispositif lumineux dont l’apparence extérieure, lorsqu’il est éteint, est de couleur sombre et homogène à la lumière du jour. [04] The present invention aims to solve this problem by proposing a light device whose external appearance, when off, is dark in color and homogeneous in daylight.
OBJET DE L’INVENTION OBJECT OF THE INVENTION
[05] Afin de remédier à l’inconvénient précité de l’état de la technique, la présente invention propose un dispositif lumineux pour véhicule automobile, comprenant un boîtier optique dans lequel sont présents une source de lumière et un réflecteur optique. Le réflecteur optique est agencé pour diriger un faisceau lumineux, émis par une source de lumière, à travers une ouverture du boîtier optique. L’ouverture du boîtier optique est obturée par un voyant extérieur afin de protéger des intempéries la source de lumière et le réflecteur optique. [05] In order to overcome the aforementioned drawback of the state of the art, the present invention proposes a light device for a motor vehicle, comprising an optical box in which a light source and an optical reflector are present. The optical reflector is arranged to direct a light beam, emitted by a light source, through an opening of the optical housing. The opening of the optical box is closed by an external indicator to protect the light source and the optical reflector from inclement weather.
[06] L’invention se caractérisé en ce que le voyant extérieur a une couleur de ton sombre à la lumière du jour, et en ce qu’un écran translucide est interposé entre le réflecteur optique et le voyant extérieur, l’écran translucide étant distant du voyant extérieur. [06] The invention is characterized in that the outside light has a dark color in the light of day, and in that a translucent screen is interposed between the optical reflector and the external light, the translucent screen being remote from the outside light.
[07] Le voyant extérieur a une couleur de ton sombre ou de ton obscur, afin d’assombrir l’intérieur du boîtier optique lorsque le dispositif lumineux est éteint et exposé à la lumière du jour. De préférence, le voyant extérieur se caractérise par une couleur homogène à la lumière du jour. De façon avantageuse, un écran translucide est interposé entre le réflecteur optique et le voyant extérieur, de manière à homogénéiser la lumière du jour réfléchie par les différents éléments présents à l’intérieur du boîtier optique. L’écran translucide est placé à distance du voyant extérieur afin d’atténuer le contraste d’intensité lumineuse de la lumière du jour réfléchie par les différents éléments constituant le boîtier optique. Un espace suffisant est maintenu entre l’écran translucide et le voyant extérieur, pour favoriser une meilleure dissipation de l’humidité entre l’écran translucide et le voyant extérieur. [07] The outside light has a dark tone or dark tone to darken the inside of the light box when the light is off and exposed to daylight. Preferably, the outside light is characterized by a color consistent with daylight. Advantageously, a translucent screen is interposed between the optical reflector and the outer light, so as to homogenize the daylight reflected by the various elements present inside the optical housing. The translucent screen is placed at a distance from the outside light to reduce the contrast in light intensity of the daylight reflected by the different elements constituting the optical box. Sufficient space is maintained between the translucent screen and the outside light, to promote a better dissipation of moisture between the translucent screen and the external light.

De préférence le voyant extérieur à une couleur dont les coordonnées trichromatiques sont de l’ordre de 0,441 pour le rouge, 0,408 pour le vert et 0,153 pour le bleu. Selon un mode de réalisation préféré, le voyant extérieur est de couleur noire. Bien entendu, la couleur du voyant extérieur peut varier en fonction de la couleur de la carrosserie du véhicule automobile sur lequel le dispositif lumineux est destiné à être monté. Ainsi, la couleur du voyant extérieur peut aussi être de couleur bleu, rouge ou autre. [09] Selon une autre variante de réalisation de l’invention, l’écart entre l’écran translucide et le voyant extérieur est compris entre 1 mm et 10 mm, de préférence entre 2 mm et 4 mm. Ces plages de valeurs sont favorables pour obtenir un dispositif lumineux d’apparence très sombre à la lumière du jour et lorsqu’il est éteint, tout en limitant son encombrement selon la direction de propagation de la lumière émise par la source de lumière dudit dispositif. [08] According to another embodiment of the invention, the external indicator has a color whose trichromatic coordinates are in the following ranges of values: for the red between 0.4 and 0.5; for green between 0.35 and 045 and for blue between 0.1 and 0.2. Preferably, the outside light with a color whose trichromatic coordinates are of the order of 0.441 for the red, 0.408 for the green and 0.153 for the blue. According to a preferred embodiment, the external indicator is black. Of course, the color of the outer light may vary depending on the color of the body of the motor vehicle on which the light device is intended to be mounted. Thus, the color of the external indicator can also be blue, red or other color. [09] According to another embodiment of the invention, the distance between the translucent screen and the external indicator is between 1 mm and 10 mm, preferably between 2 mm and 4 mm. These ranges of values are favorable to obtain a luminous device of very dark appearance in the light of day and when it is off, while limiting its size in the direction of propagation of the light emitted by the light source of said device.

[11] According to another embodiment of the invention, the outer light absorbs between 80% and 95% of the intensity of daylight, preferably of the order of 90%.
[12] Selon une autre variante de réalisation de l’invention, l’écran translucide diffuse la lumière du jour, de façon à limiter l’intensité de la lumière du jour entre 30% et 10%, de préférence de l’ordre de 15% à l’intérieur du réflecteur optique. Selon cette variante, le boîtier optique est de préférence opaque à la lumière du jour, de sorte que la lumière du jour pénètre uniquement dans le boîtier optique à travers le voyant extérieur. [12] According to another embodiment of the invention, the translucent screen diffuses daylight, so as to limit the intensity of daylight between 30% and 10%, preferably of the order of 15% inside the optical reflector. According to this variant, the optical box is preferably opaque to daylight, so that daylight only enters the optical box through the outside light.
[13] Selon une autre variante de réalisation de l’invention, un faisceau lumineux sous incidence normale est diffusé par l’écran translucide, dans une plage d’angle de diffusion comprise entre 0° et 41 °, de préférence entre 0° et 20°. [13] According to another embodiment of the invention, a light beam under normal incidence is diffused by the translucent screen, in a range of diffusion angle between 0 ° and 41 °, preferably between 0 ° and 20 °.
[14] Selon une autre variante de réalisation de l’invention, l’écran translucide comporte un motif visible, à travers le voyant extérieur, lorsque la source de lumière est allumée. Selon un mode de réalisation préféré, le motif est sérigraphié et/ou incrusté dans l’écran translucide. [14] According to another embodiment of the invention, the translucent screen has a visible pattern, through the outer light, when the light source is turned on. According to a preferred embodiment, the pattern is screen printed and / or embedded in the translucent screen.
[15] Selon une autre variante de réalisation de l’invention, le dispositif lumineux comprend un cadre, placé entre la source de lumière et l’écran translucide, le cadre comporte au moins une ouverture laissant passer au moins une partie du faisceau lumineux émis par la source de lumière. De préférence, le cadre masque au moins une partie de l’intérieur du boîtier afin de favoriser une plus grande homogénéisation de la lumière réfléchie par l’intérieur dudit boîtier.

[21] Pour rappel, l’invention propose un dispositif lumineux dont l’apparence extérieure, lorsqu’il est éteint, est de couleur sombre et homogène à la lumière du jour. As a reminder, the invention proposes a luminous device whose external appearance, when extinguished, is dark in color and homogeneous in the light of day.
[22] Les figures 1 et 2 illustrent un mode de réalisation non limitatif d’un dispositif lumineux 2 selon l’invention, destiné à être utilisé comme feu de position ou lanterne par un véhicule automobile. [22] Figures 1 and 2 illustrate a non-limiting embodiment of a light device 2 according to the invention for use as a position light or lantern by a motor vehicle.
[23] Le dispositif lumineux 2 comporte un boîtier optique 4 dans lequel sont présents deux sources de lumière 6A et 6B. Une première source de lumière 6A est configurée pour émettre un faisceau lumineux de couleur ambre afin de signaler l’intention du conducteur de changer de voie ou de tourner. Une deuxième source de lumière 6B est configurée pour émettre un faisceau lumineux de couleur rouge pour signaler la position du véhicule automobile et/ou son freinage. Chaque source de lumière comporte une ou plusieurs diodes électroluminescentes maintenues au niveau d’une même face avant d’une plaque 8 de circuit imprimé. De manière connue, la plaque 8 permet à un dispositif de contrôle non représenté sur les figures, de commander le fonctionnement des sources de lumière 6A et 6B. [23] The light device 2 comprises an optical box 4 in which there are present two light sources 6A and 6B. A first light source 6A is configured to emit an amber light beam to signal the driver's intention to change lanes or turn. A second light source 6B is configured to emit a red light beam to signal the position of the motor vehicle and / or its braking. Each light source comprises one or more light-emitting diodes held at the same front face of a printed circuit board. In known manner, the plate 8 allows a control device not shown in the figures, to control the operation of the light sources 6A and 6B.
[24] Afin de limiter échauffement des sources de lumière lors de leur utilisation, le boîtier optique 4 comporte également un radiateur thermique 10 qui s’étend le long de la face arrière de la plaque. La chaleur émise par le radiateur thermique 10 est évacuée à l’extérieur du boîtier optique 4 par l’intermédiaire d’un évent 12. [24] In order to limit heating of the light sources during their use, the optical box 4 also comprises a heat sink 10 which extends along the rear face of the plate. The heat emitted by the heat radiator 10 is discharged outside the optical housing 4 via a vent 12.
[25] Les sources de lumière sont orientées de manière à ce que leur faisceau lumineux passe à travers une même ouverture 14 du boîtier optique 4. L’ouverture 14 est située à une distance des sources de lumière 6, comprise entre 25 mm et 80 mm, de préférence de l’ordre de 50 mm. Afin de diriger selon une direction souhaitée les faisceaux lumineux à travers l’ouverture 14, il est associé à chaque source de lumière un réflecteur optique 16. Les réflecteurs optiques se caractérisent par une surface à fort coefficient de réflexion au niveau de leur face interne. [26] Pour protéger des intempéries les éléments présents dans le boîtier optique 4, l’ouverture 14 est obturée par un voyant extérieur 18. Bien entendu, le voyant extérieur est partiellement transparent aux faisceaux lumineux émis par les sources de lumière, afin que le dispositif lumineux puisse émettre des signaux lumineux visibles par d’autres conducteurs. [25] The light sources are oriented so that their light beam passes through the same opening 14 of the optical housing 4. The opening 14 is located at a distance from the light sources 6, between 25 mm and 80 mm, preferably of the order of 50 mm. In order to direct the light beams through the opening 14 in a desired direction, it is associated with each light source an optical reflector 16. The optical reflectors are characterized by a surface with a high reflection coefficient at their inner face. [26] In order to protect the elements present in the optical box 4 from inclement weather, the opening 14 is closed by an external indicator light 18. Of course, the external indicator is partially transparent to the light beams emitted by the light sources, so that the light device can emit light signals visible to other drivers.
[27] Comme mentionné ci-dessus, d’ordinaire le voyant extérieur est transparent ou translucide à la lumière du jour. Les éléments présents dans le boîtier optique sont donc visibles à travers le voyant extérieur ce qui modifie localement et très fortement l’aspect de la carrosserie du véhicule automobile à la lumière du jour. [27] As mentioned above, the exterior light is usually transparent or translucent in daylight. The elements present in the optical box are thus visible through the external indicator which modifies locally and very strongly the appearance of the body of the motor vehicle in the light of day.
[28] Afin de résoudre ce problème, la présente invention propose de substituer les voyants extérieurs habituellement utilisés, par un voyant extérieur 18 se caractérisant par une couleur homogène de teinte sombre ou obscure afin de limiter très fortement la quantité de lumière du jour passant à travers ledit voyant. Par les termes « lumière du jour », on entend toutes les formes de lumières provenant du soleil, directe et indirecte. Le voyant extérieur a une couleur dont les coordonnées trichromatiques sont comprises dans les plages de valeurs suivantes : pour le rouge entre 0,4 et 0,5 ; pour le vert entre 0,35 et 045 et pour le bleu entre 0,1 et 0,2. De préférence le voyant extérieur à une couleur dont les coordonnées trichromatiques sont de l’ordre de 0,441 pour le rouge, 0,408 pour le vert et 0,153 pour le bleu. Le voyant extérieur 18 a une épaisseur comprise entre 2 mm et 3,5 mm, de préférence de l’ordre de 2,2 mm. L’épaisseur du voyant extérieur 18 est ici définie selon la direction d’incidence des faisceaux lumineux émis par les sources de lumière 6 sur ledit voyant. Le voyant extérieur 18 se caractérise par une absorption de la lumière du jour qui est comprise entre 80% et 95%, de préférence de l’ordre de 90%. Le voyant extérieur 18 est réalisé à partir de l’un des matériaux suivants : polyméthacrylate de méthyle (PMMA) ou polycarbonate (PC). [28] In order to solve this problem, the present invention proposes to substitute the external indicators usually used, by an external indicator 18 characterized by a homogeneous color of dark or dark hue in order to very much limit the amount of daylight passing through. through said indicator. By the terms "daylight" we mean all forms of light coming from the sun, direct and indirect. The outer light has a color whose trichromatic coordinates are in the following ranges: for red between 0.4 and 0.5; for green between 0.35 and 045 and for blue between 0.1 and 0.2. Preferably, the outside light with a color whose trichromatic coordinates are of the order of 0.441 for the red, 0.408 for the green and 0.153 for the blue. The outer light 18 has a thickness of between 2 mm and 3.5 mm, preferably of the order of 2.2 mm. The thickness of the outer light 18 is here defined according to the direction of incidence of the light beams emitted by the light sources 6 on said light. The outer light 18 is characterized by daylight absorption which is between 80% and 95%, preferably of the order of 90%. The external indicator 18 is made from one of the following materials: polymethylmethacrylate (PMMA) or polycarbonate (PC).
[29] Afin de favoriser une couleur de teinte homogène du voyant extérieur à la lumière du jour, le boîtier optique 4 comporte également un cadre 20 prenant appui sur les parois internes du boîtier optique 4. Le cadre 20 obture une partie dudit boîtier, comprenant les sources de lumière 6 et les réflecteurs optiques 16. Le cadre comporte une face avant 22 parallèle ou sensiblement parallèle au voyant extérieur 18. La face avant 22 est opaque à la lumière du jour afin de former un fond de couleur sombre et homogène. Le cadre comporte également des passages 24 prolongeant les réflecteurs optiques, de manière à permettre aux sources de lumière d’éclairer le voyant extérieur 18. [29] In order to promote a color of homogeneous hue of the outside light in the light of day, the optical box 4 also includes a frame 20 bearing on the inner walls of the optical housing 4. The frame 20 closes a portion of said housing, comprising the light sources 6 and the optical reflectors 16. The frame comprises a front face 22 parallel or substantially parallel to the external indicator 18. The front face 22 is opaque to daylight to form a dark and homogeneous background color. The frame also includes passages 24 extending the optical reflectors, so as to allow the light sources to illuminate the outer light 18.
[30] Toute la surface de la face avant 22 du cadre 20 est recouverte par un écran translucide 26. L’écran translucide 26 se caractérise par une épaisseur comprise entre 0.1 mm et 3 mm, de préférence de l’ordre de 0.3 mm. L’épaisseur de l’écran translucide est ici définie selon la direction d’incidence des faisceaux lumineux émis par les sources de lumière 6A et 6B sur ledit écran. L’écran translucide diffuse la lumière du jour de façon à limiter dans chaque réflecteur optique 16 l’intensité de la lumière du jour entre 30% et 10%, de préférence de l’ordre de 15%. De préférence, la face avant 22 de l’écran translucide en vis-à-vis du voyant extérieur 18, favorise la réflexion d’un faisceau lumineux sous incidence normale, dans une plage d’angle de réflexion comprise entre 0° et 41 °, de préférence entre 0° et 20°. Pour cela, la face avant 28 de l’écran translucide 26 peut comporter des motifs en relief réalisés par une technique de moulage. L’écran translucide est réalisé à partir de l’un des matériaux suivants : polyméthacrylate de méthyle (PMMA) ou polycarbonate (PC). [30] The entire surface of the front face 22 of the frame 20 is covered by a translucent screen 26. The translucent screen 26 is characterized by a thickness of between 0.1 mm and 3 mm, preferably of the order of 0.3 mm. The thickness of the translucent screen is here defined according to the direction of incidence of the light beams emitted by the light sources 6A and 6B on said screen. The translucent screen diffuses the daylight so as to limit in each optical reflector 16 the intensity of the daylight between 30% and 10%, preferably of the order of 15%. Preferably, the front face 22 of the translucent screen vis-à-vis the outer indicator 18, promotes reflection of a light beam at normal incidence, in a range of reflection angle between 0 ° and 41 ° preferably between 0 ° and 20 °. For this, the front face 28 of the translucent screen 26 may comprise relief patterns made by a molding technique. The translucent screen is made from one of the following materials: polymethylmethacrylate (PMMA) or polycarbonate (PC).
[31] Le cadre 20 maintient l’écran translucide 26 à une distance du voyant extérieur 18 qui est comprise entre 1 mm et 10 mm, de préférence entre 2 mm et 4 mm, de manière préférée de l’ordre de 3 mm. Dans ces plages de valeurs, on favorise à la fois la circulation d’air entre l’écran translucide 26 et le voyant extérieur 18 afin d’éviter un phénomène de condensation, et en même temps une homogénéisation de la teinte dudit voyant à la lumière du jour. Éventuellement, le boîtier optique 4 peut comporter des évents non représentés, pour favoriser un écoulement d’air entre le cadre 20 et le voyant extérieur 18. [31] The frame 20 keeps the translucent screen 26 at a distance from the outer light 18 which is between 1 mm and 10 mm, preferably between 2 mm and 4 mm, preferably of the order of 3 mm. In these ranges of values, it promotes both the air flow between the translucent screen 26 and the outer sight 18 to avoid a phenomenon of condensation, and at the same time a homogenization of the hue of said indicator light of the day. Optionally, the optical box 4 may comprise unrepresented vents, to promote an air flow between the frame 20 and the outer sight 18.
[32] Bien entendu, les sources de lumière 6A et 6B mentionnées ci-dessus sont choisies de sorte à pouvoir émettre à travers le voyant extérieur 18 des signaux lumineux conforment aux normes en vigueur. À titre d’exemple non limitatif, la première source de lumière 6A est configurée pour émettre un faisceau lumineux dont l’intensité lumineuse est comprise entre 5 Im et 200 Im selon la fonction souhaitée. La deuxième source de lumière 6B est configurée pour émettre un faisceau lumineux dont l’intensité lumineuse est comprise entre 5 Im et 200 Im, selon de la fonction souhaitée. [32] Of course, the light sources 6A and 6B mentioned above are chosen so that they can emit through the external indicator 18 light signals in accordance with the standards in force. By way of nonlimiting example, the first light source 6A is configured to emit a light beam whose luminous intensity is between 5 Im and 200 Im depending on the desired function. The second light source 6B is configured to emit a light beam whose luminous intensity is between 5 Im and 200 Im, according to the desired function.
[33] En conclusion, le dispositif lumineux 2 selon l’invention se caractérise par un agencement particulier entre le voyant extérieur 18 de couleur sombre, le cadre 20 et l’écran translucide 26. Comme illustré sur la figure 2, cet agencement permet avantageusement d’absorber la majorité de l’intensité lumineuse de la lumière du jour 30, de sorte que les sources de lumière 6A et 6B et leur réflecteur optique 16 ne soient pas visibles depuis l’extérieur du dispositif lumineux 2. De ce fait, lorsqu’il est éteint, le dispositif lumineux apparait de couleur très sombre et très homogène à la lumière du jour. Un dispositif lumineux selon l’invention permet ainsi d’éviter, ou du moins de diminuer, un contraste de couleur avec la carrosserie d’un véhicule automobile de couleur sombre. [33] In conclusion, the luminous device 2 according to the invention is characterized by a particular arrangement between the dark-colored outside light 18, the frame 20 and the translucent screen 26. As illustrated in FIG. 2, this arrangement advantageously allows absorb the majority of the light intensity of the daylight 30, so that the light sources 6A and 6B and their optical reflector 16 are not visible from outside the light device 2. Therefore, when it is off, the luminous device appears very dark in color and very homogeneous in the light of day. A light device according to the invention thus makes it possible to avoid, or at least to reduce, a color contrast with the bodywork of a dark-colored motor vehicle.
