Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention concerne un dispositif d'éclairage actif portable au poignet d'une personne, notamment pour éclairer un chemin emprunté lorsque la lumière ambiante est insuffisante. Le dispositif d'éclairage actif portable peut être sous la forme d'une montre électronique ou électromécanique, ou d'un bracelet à composants électroniques.The invention relates to an active lighting device portable to a person's wrist, in particular for illuminating a path taken when ambient light is insufficient. The portable active lighting device may be in the form of an electronic or electromechanical watch, or of a bracelet with electronic components.

ETAT DE LA TECHNIQUESTATE OF THE ART

Pour éclairer de manière adéquate un chemin ou une route empruntée par une personne à pieds, il est connu d'utiliser un dispositif d'éclairage portable avec un réglage adapté de l'intensité de la lumière générée par une ou des sources de lumière. Un tel dispositif d'éclairage peut aussi être utilisé pour une promenade ou une course à pieds dans l'obscurité. Un tel dispositif d'éclairage peut être disposé par exemple sur la tête d'une personne et enclenché manuellement au moment de la promenade ou de la course dans l'obscurité.To adequately illuminate a path or a road taken by a person on foot, it is known to use a portable lighting device with a suitable adjustment of the intensity of the light generated by one or more light sources. Such a lighting device can also be used for a walk or a run in the dark. Such a lighting device can be arranged for example on the head of a person and switched on manually when walking or running in the dark.

On peut citer à ce titre la demande de brevet US 2018/0112839 A1 , qui décrit un bracelet avec une source de lumière orientable. Cependant rien n'est défini concernant l'orientation de la source de lumière tenant compte du mouvement du bracelet au cours d'une marche ou d'une course. Ainsi un tel bracelet à source de lumière ne permet pas d'éclairer correctement le chemin emprunté par le promeneur ou le coureur portant ledit bracelet, ce qui constitue un inconvénient.We can cite in this respect the patent application US 2018/0112839 A1 , which describes a bracelet with an orientable light source. However, nothing is defined concerning the orientation of the light source taking into account the movement of the bracelet during a walk or a run. Thus, such a light source bracelet does not make it possible to correctly illuminate the path taken by the walker or the runner wearing said bracelet, which constitutes a drawback.

La demande de brevet US 2017/0241634 A1 décrit un bracelet avec possibilité de fixer et connecter différentes sources de lumière, mais comme pour le précédent document les sources de lumière restent selon une direction bien définie et ne permettent pas d'éclairer correctement le chemin emprunté par le promeneur ou le coureur portant ledit bracelet, ce qui constitue un inconvénient.The patent application US 2017/0241634 A1 describes a bracelet with the possibility of fixing and connecting different light sources, but as for the previous document the light sources remain in a well-defined direction and do not allow the path taken by the walker or runner wearing said bracelet to be correctly illuminated , which is a drawback.

Enfin, on connaît le document US2012/140451 A1 , qui décrit un dispositif d'éclairage selon le préambule de la revendication 1 annexée .Finally, we know the document US2012 / 140451 A1 , which describes an illumination device according to the preamble of the appended claim 1.

RESUMÉ DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention a donc pour but de pallier les inconvénients cités ci-dessus pour réaliser un dispositif d'éclairage actif portable au poignet d'une personne facile d'utilisation et sans complication pour permettre un bon éclairage d'un chemin emprunté par la personne tout en tenant compte du mouvement du poignet de la personne.The object of the invention is therefore to overcome the drawbacks mentioned above to produce an active lighting device portable to the wrist of a person easy to use and without complications to allow good lighting of a path taken by the person. while taking into account the movement of the person's wrist.

A cet effet, l'invention concerne un dispositif d'éclairage actif portable placé au poignet d'une personne, qui comprend les caractéristiques de la revendication indépendante 1.To this end, the invention relates to a portable active lighting device placed on the wrist of a person, which comprises the features of independent claim 1.

Des formes d'exécution particulières du dispositif d'éclairage sont définies dans les revendications dépendantes 2 à 14.Particular embodiments of the lighting device are defined in dependent claims 2 to 14.

Un avantage du dispositif d'éclairage selon l'invention réside dans le fait que le dispositif d'éclairage en utilisation permet de maintenir une même direction de la lumière générée par des premières sources de lumière pour éclairer un chemin à suivre par une personne portant le dispositif d'éclairage. Ainsi les premières sources de lumière sont sélectionnées par une unité de contrôle sur la base de mesures d'un capteur de mouvement de manière à ne pas suivre le mouvement du poignet de la personne lors d'une marche ou d'une course à pieds pour garder une illumination toujours dans une même direction vers l'avant.An advantage of the lighting device according to the invention lies in the fact that the lighting device in use makes it possible to maintain the same direction of the light generated by the first light sources in order to illuminate a path to be followed by a person wearing the lighting device. Thus the first light sources are selected by a control unit on the basis of measurements from a movement sensor so as not to follow the movement of the person's wrist when walking or running for keep an illumination always in the same forward direction.

Avantageusement, il peut être prévu des secondes sources de lumière, qui sont disposées dans le dispositif d'éclairage pour générer une illumination vers l'arrière et d'une autre couleur que l'illumination vers l'avant pour signaler la présence de la personne utilisant le dispositif d'éclairage à des véhicules ou d'autres personnes venant de l'arrière.Advantageously, second light sources can be provided, which are arranged in the lighting device to generate illumination towards the rear and of a color other than illumination towards the rear. front to signal the presence of the person using the lighting device to vehicles or other people coming from behind.

De préférence, le dispositif d'éclairage peut être sous la forme d'une montre-bracelet, voire uniquement d'un bracelet à composants électroniques. Dans le cas d'une montre-bracelet, les sources de lumière peuvent être montées sur une portion du boîtier, par exemple sur une lunette de montre pour générer chacune une fois activée un faisceau de lumière dans une direction radiale vers l'extérieur du boîtier, c'est-à-dire sensiblement dans une direction parallèle à un cadran et perpendiculairement à une carrure du boîtier. Chaque faisceau de lumière d'une source de lumière activée est d'une direction différente d'une autre source de lumière activée.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Dans la description suivante, il est fait référence à un dispositif d'éclairage actif portable pour être placé au poignet d'une personne. Tous les composants électroniques, qui sont bien connus d'un homme du métier dans ce domaine technique, ne sont décrits que de manière simplifiée. Le dispositif d'éclairage peut avantageusement être sous la forme d'une montre-bracelet ou d'un bracelet à composants électroniques.In the following description, reference is made to an active lighting device portable to be placed on a person's wrist. All the electronic components, which are well known to a person skilled in the art in this technical field, are only described in a simplified manner. The lighting device can advantageously be in the form of a wristwatch or a bracelet with electronic components.

Il est à noter que sous la forme d'une montre-bracelet ne veut pas forcément signifier qu'il s'agit intrinsèquement d'une montre-bracelet. Par contre, la configuration du dispositif d'éclairage est d'une forme identique à celle d'une montre-bracelet avec un boîtier, un verre fermant le dessus du boîtier pour visionner des informations sur un cadran ou un affichage à cristaux liquides, et un bracelet à un ou deux brins relié au boîtier pour placer le dispositif d'éclairage autour du poignet d'une personne.It should be noted that in the form of a wristwatch does not necessarily mean that it is inherently a wristwatch. On the other hand, the configuration of the lighting device is of a shape identical to that of a wristwatch with a case, a glass closing the top of the case to view information on a dial or a liquid crystal display, and a one or two strand bracelet connected to the case for placing the lighting device around a person's wrist.

La figure 1 représente de manière simplifiée les différents principaux composants d'un dispositif 1 d'éclairage actif portable à placer au poignet d'une personne selon l'invention. Le dispositif 1 d'éclairage est sous la forme d'une montre-bracelet avec au moins un boîtier relié par un bracelet à un ou deux brins, ou d'un bracelet à composants électroniques. Le dispositif 1 d'éclairage peut aussi être une montre-bracelet comme expliqué aux figures 2 à 4.The figure 1 shows in a simplified manner the various main components of a portable active lighting device 1 to be placed on the wrist of a person according to the invention. The lighting device 1 is in the form of a wristwatch with at least one case connected by a bracelet with one or two strands, or a bracelet with electronic components. The lighting device 1 can also be a wristwatch as explained in figures 2 to 4 .

Le dispositif 1 d'éclairage comprend au moins un capteur de mouvement 3, 4 relié à une unité de contrôle 2, et au moins des premières sources de lumière 5 reliées à l'unité de contrôle 2. L'unité de contrôle 2 est reliée à une source d'alimentation continue non représentée. Cette source d'alimentation électrique est de préférence une source de tension continue, qui provient d'une batterie rechargeable ou primaire, ou qui est extraite et redressée d'un rayonnement électromagnétique reçu. Le dispositif 1 d'éclairage peut être activé manuellement par l'action d'un bouton interrupteur ou d'une touche tactile sur le boîtier ou le verre fermant le boîtier, comme expliqué ci-après en référence aux figures 2 et 3.The lighting device 1 comprises at least one movement sensor 3, 4 connected to a control unit 2, and at least first light sources 5 connected to the control unit 2. The control unit 2 is connected to a DC power source not shown. This source The power supply is preferably a DC voltage source, which comes from a rechargeable or primary battery, or which is extracted and rectified from received electromagnetic radiation. The lighting device 1 can be activated manually by the action of a switch button or a tactile key on the housing or the glass closing the housing, as explained below with reference to figures 2 and 3 .

Pour un dispositif 1 d'éclairage sous la forme d'une montre-bracelet, les premières sources de lumière 5 peuvent être placées sur la carrure du boîtier fermé par un verre, ou sur une lunette fixée sur la carrure du boîtier comme expliqué ci-après en référence aux figures 2 et 3. Le dispositif 1 d'éclairage peut encore comprendre des secondes sources de lumière 6 reliées à l'unité de contrôle 2. Ces secondes sources de lumière peuvent aussi être placées sur la carrure du boîtier, par exemple du boîtier de montre fermé par un verre, ou sur une lunette fixée sur la carrure du boîtier.For a lighting device 1 in the form of a wristwatch, the first light sources 5 can be placed on the middle part of the case closed by a glass, or on a bezel fixed on the middle part of the case as explained below. after with reference to figures 2 and 3 . The lighting device 1 can also include second light sources 6 connected to the control unit 2. These second light sources can also be placed on the middle part of the case, for example of the watch case closed by a glass, or on a bezel attached to the middle of the case.

Les premières sources de lumière 5 sont prévues pour générer une fois activées chacune un faisceau de lumière d'orientation différente de chaque autre source de lumière. Ainsi, cela permet à l'unité de contrôle 2 de sélectionner automatiquement sur la base de mesures du capteur de mouvement 3, 4 certaines premières sources de lumière 5 de manière à garder une illumination L1 du chemin suivi par la personne portant le dispositif 1 d'éclairage toujours dans une même direction. La sélection des premières sources de lumière 5 dépend du mouvement du poignet de la personne portant le dispositif 1 d'éclairage pour éclairer le chemin à suivre dans une même direction vers l'avant malgré le mouvement du poignet.The first light sources 5 are provided to generate, once activated, each a beam of light with a different orientation from each other light source. Thus, this allows the control unit 2 to automatically select on the basis of measurements from the motion sensor 3, 4 certain first light sources 5 so as to keep an illumination L1 of the path followed by the person wearing the device 1 d lighting always in the same direction. The selection of the first light sources 5 depends on the movement of the wrist of the person wearing the lighting device 1 to illuminate the path to be followed in the same forward direction despite the movement of the wrist.

Les secondes sources de lumière 6 sont aussi prévues pour générer une fois activées chacune un faisceau de lumière d'orientation différente de chaque autre source de lumière. L'unité de contrôle 2 sélectionne aussi automatiquement sur la base de mesures du capteur de mouvement 3, 4 certaines secondes sources de lumière 6 pour générer une illumination L2 opposée à l'illumination L1 tout en gardant l'illumination L2 dans une même direction opposée à l'illumination L1.The second light sources 6 are also provided to generate, once activated, each a beam of light with a different orientation from each other light source. The control unit 2 also automatically selects based on measurements from the motion sensor 3, 4 certain second light sources 6 to generate an L2 illumination opposite to the L1 illumination while keeping the L2 illumination in the same opposite direction. to L1 illumination.

Dans le cas d'un dispositif 1 d'éclairage avec les premières et secondes sources de lumière 5, 6, il peut être envisagé d'avoir l'illumination L1 des premières sources de lumière 5 de couleur différente de l'illumination L2 des secondes sources de lumière 6. Par exemple l'illumination L1 pour éclairer vers l'avant de la personne portant ledit dispositif 1 d'éclairage peut être une lumière blanche, alors que l'illumination L2 pour fournir une lumière vers l'arrière afin de signaler la présence de la personne sur un chemin en marche ou en course peut être une lumière rouge.In the case of a lighting device 1 with the first and second light sources 5, 6, it can be envisaged to have the illumination L1 of the first light sources 5 of a different color from the illumination L2 of the seconds. light sources 6. For example, the illumination L1 for illuminating towards the front of the person wearing said illumination device 1 may be white light, while the illumination L2 for providing light towards the rear in order to signal the presence of the person on a walking or running path can be a red light.

Les secondes sources de lumière 6 peuvent aussi être contrôlées par l'unité de contrôle 2 de manière à fournir une seconde illumination L2 clignotante de couleur rouge. Ceci permet de générer plus de visibilité pour signaler la présence de la personne utilisant le dispositif d'éclairage à des véhicules ou d'autres personnes venant de l'arrière, et diminue encore la consommation électrique.The second light sources 6 can also be controlled by the control unit 2 so as to provide a second flashing illumination L2 of red color. This makes it possible to generate more visibility to signal the presence of the person using the lighting device to vehicles or other people coming from behind, and further reduces the power consumption.

Bien entendu, il peut aussi être envisagé d'avoir des premières sources de lumière bicolores 5. Dans ces conditions, il n'y a pas de secondes sources de lumière 6, mais les premières sources de lumière doivent être sélectionnées par l'unité de contrôle pour générer une illumination L1 vers l'avant d'une première couleur et une illumination L2 vers l'arrière d'une seconde couleur lors d'une marche ou d'une course à pieds. La seconde illumination L2 peut être aussi clignotante.Of course, it can also be envisaged to have first two-color light sources 5. Under these conditions, there are no second light sources 6, but the first light sources must be selected by the control unit. control for generating L1 forward illumination of a first color and L2 rearward illumination of a second color when walking or running. The second L2 illumination can also be flashing.

Chaque première ou seconde source de lumière peut être une diode électroluminescente LED, voire une combinaison de deux diodes électroluminescentes LED montées par exemple tête-bêche pour d'une part fournir un faisceau lumineux d'une première couleur lors d'une polarisation directe ou d'une seconde couleur différente de la première couleur lors d'une polarisation inverse.Each first or second light source can be a light-emitting diode LED, or even a combination of two light-emitting diodes LED mounted for example head-to-tail for on the one hand to provide a light beam of a first color during a direct polarization or d 'a second color different from the first color on reverse bias.

Le dispositif 1 d'éclairage peut comprendre deux capteurs de mouvement, tels qu'un magnétomètre 3 et un accéléromètre 4 pour fournir des signaux de mesure à l'unité de contrôle 2. Le magnétomètre 3 et l'accéléromètre 4 peuvent être du type triaxial. Ladite unité de contrôle 2 peut aussi comprendre au moins une mémoire 21 pour mémoriser des mesures effectuées par le ou les capteurs de mouvement 3, 4 et au moins un algorithme de calcul pour la gestion et les calculs des mesures effectuées par les capteurs. L'unité de contrôle 2 peut encore comprendre une propre base de temps 22 telle qu'un oscillateur à basse fréquence, qui peut être un oscillateur à quartz horloger ou MEMS, de manière à cadencer les opérations de mesure et de contrôle des premières et secondes sources de lumière 5, 6. Ainsi, cette unité de contrôle 2 peut être un microcontrôleur.The lighting device 1 can include two motion sensors, such as a magnetometer 3 and an accelerometer 4 to supply measurement signals to the control unit 2. The magnetometer 3 and the accelerometer 4 can be of the triaxial type. Said control unit 2 can also include at least one memory 21 for storing measurements made by the movement sensor (s) 3, 4 and at least one calculation algorithm for the management and calculations of the measurements made by the sensors. The control unit 2 can also include its own time base 22 such as a low frequency oscillator, which can be a clockwork quartz oscillator or MEMS, so as to clock the measurement and control operations of the first and second seconds. light sources 5, 6. Thus, this control unit 2 can be a microcontroller.

Il est encore à noter que l'unité de contrôle 2 une fois activée peut prendre en compte la position initiale par au moins un capteur de mouvement 3, 4 du poignet de la personne portant le dispositif 1 d'éclairage. Ceci permet de calibrer initialement la direction de la première illumination L1 et aussi celle de la seconde illumination L2 avant un départ en marche ou pour une course à pieds. Ainsi, une direction d'illumination L1 par exemple une fois calibrée permet d'avoir toujours cette direction d'illumination L1 maintenue fixe quelque-soit le mouvement du poignet, ce qui est recherché pour bien éclairer le chemin à suivre dans l'obscurité.It should also be noted that the control unit 2 once activated can take into account the initial position by at least one movement sensor 3, 4 of the wrist of the person wearing the lighting device 1. This makes it possible to initially calibrate the direction of the first illumination L1 and also that of the second illumination L2 before a walking start or for a run. Thus, a direction of illumination L1, for example once calibrated, makes it possible to always have this direction of illumination L1 kept fixed whatever the movement of the wrist, which is sought to properly illuminate the path to follow in the dark.

En principe, il n'y a pas de réglage d'intensité de lumière des différentes sources de lumière activées, mais il est cherché plutôt d'avoir l'intensité maximale à chaque illumination générée par les sources de lumière activées par l'unité de contrôle 2.In principle, there is no adjustment of the light intensity of the different activated light sources, but it is rather sought to have the maximum intensity at each illumination generated by the light sources activated by the control unit. control 2.

Les figures 2 et 3 représentent une forme d'exécution d'un dispositif 1 d'éclairage actif portable en position de fonctionnement. Le dispositif 1 d'éclairage est ici une montre-bracelet. Cette montre-bracelet 1 comprend un boîtier avec une carrure 12 fermée par un fond 14 avec une garniture d'étanchéité 13, le boîtier étant fermé par un verre de montre 18 fixé par un joint 17 à une lunette 10, qui elle-même est fixée sur la carrure 12 avec une autre garniture d'étanchéité 11. A travers le verre de montre 18, on peut voir un cadran 16 et des aiguilles 20 d'indication de l'heure notamment. Un bracelet 30 est relié à la carrure 12 du boîtier avec une attache pour placer le dispositif 1 d'éclairage au poignet d'une personne l'utilisant. Un bouton-poussoir 40 en figure 2, qui est monté à travers la carrure 12 pour être relié à l'unité de contrôle 2, est aussi prévu pour régler manuellement l'indication horaire ou pour initialiser et activer le dispositif 1 d'éclairage. Il peut être prévu aussi une touche tactile reliée à l'unité de contrôle 2 dans le boîtier pour initialiser et activer le dispositif 1 d'éclairage.The figures 2 and 3 show an embodiment of a portable active lighting device 1 in the operating position. The lighting device 1 is here a wristwatch. This wristwatch 1 comprises a case with a middle part 12 closed by a back 14 with a sealing gasket 13, the case being closed by a watch glass 18 fixed by a seal 17 to a bezel 10, which itself is fixed to the middle part 12 with another sealing gasket 11. Through the watch glass 18, one can see a dial 16 and hands 20 for indicating the time in particular. A bracelet 30 is connected to the middle part 12 of the case with a clip for placing the lighting device 1 on the wrist of a person using it. A push-button 40 in figure 2 , which is mounted through the middle part 12 to be connected to the control unit 2, is also provided for manually adjusting the time indication or for initializing and activating the lighting device 1. There can also be provided a touch key connected to the control unit 2 in the housing to initialize and activate the lighting device 1.

La montre-bracelet 1 comprend encore à l'intérieur du boîtier un mouvement horloger ou un module électronique horloger 19, et l'unité de contrôle 2 reliée à un ou deux capteurs de mouvement 3, 4, qui sont un magnétomètre 3 et un accéléromètre 4 par exemple. L'unité de contrôle 2 est reliée électriquement à chaque source de lumière 5, 6 comme précisé ci-dessous par l'intermédiaire d'une plaque à circuit imprimé flexible 15. De préférence, au moins les premières sources de lumière 5 sont placées en partie dans des cavités de la lunette 10 et débouchant en partie vers l'extérieur de la lunette 10, notamment une forme de lentille.The wristwatch 1 also comprises inside the case a watch movement or an electronic watch module 19, and the control unit 2 connected to one or two movement sensors 3, 4, which are a magnetometer 3 and an accelerometer 4 for example. The control unit 2 is electrically connected to each light source 5, 6 as specified below by means of a flexible printed circuit board 15. Preferably, at least the first light sources 5 are placed in line. partly in cavities of the bezel 10 and opening partly towards the outside of the bezel 10, in particular in the form of a lens.

De manière schématique en figure 2, les premières sources de lumière 5 sont disposées sur ou en partie dans la lunette 10 de montre, qui est dans ce cas de figure de forme annulaire ou circulaire. Il est prévu plusieurs premières sources de lumière 5 disposées sur une portion de cercle en périphérie de la lunette 10 en étant de préférence régulièrement espacées l'une de l'autre. Les premières sources de lumière 5 peuvent être disposées sur une portion de cercle pouvant aller jusqu'à 180° entre midi et 6 h. Chaque première source de lumière 5 est reliée électriquement à l'unité de contrôle 2 disposée dans le boîtier de montre de manière à pouvoir être activée en fonction de mesures du capteur de mouvement 3, 4, qui est aussi disposé dans le boîtier de la montre. Chaque première source de lumière 5 peut générer une fois activée un faisceau de lumière F montrée en figure 3 se dirigeant radialement vers l'extérieur du boîtier, c'est-à-dire sensiblement dans une direction parallèle au cadran 16 et perpendiculairement à la carrure 12 du boîtier. Ainsi chaque première source de lumière 5 génère un faisceau de lumière F d'orientation différente d'une autre source de lumière activée. Le faisceau de lumière F peut être sous la forme d'un cône.Schematically in figure 2 , the first light sources 5 are arranged on or partly in the watch bezel 10, which in this case is of annular or circular shape. Several first light sources 5 are provided, arranged on a portion of a circle at the periphery of the bezel 10, preferably being regularly spaced from one another. The first light sources 5 can be placed on a portion of a circle which can range up to 180 ° between noon and 6 o'clock. Each first light source 5 is electrically connected to the control unit 2 arranged in the watch case so as to be able to be activated as a function of measurements from the movement sensor 3, 4, which is also arranged in the watch case. . Each first light source 5 can generate once activated a beam of light F shown in figure 3 running radially towards the outside of the case, that is to say substantially in a direction parallel to the dial 16 and perpendicular to the middle part 12 of the case. So every first light source 5 generates a light beam F of different orientation from another activated light source. The light beam F can be in the form of a cone.

Dans le cas présent, pour la génération d'une première illumination L1, il est prévu par exemple quatre premières sources de lumière 5 activées par l'unité de contrôle 2 et montrées en gris sur la figure 2, et définissant un premier secteur illuminé. Les autres premières sources de lumière 5 sont inactives. Cependant lors d'un mouvement du poignet de la personne selon un angle θ, une autre sélection et activation de premières sources de lumière 5 successives est effectuée par l'unité de contrôle 2, par exemple quatre autres premières sources de lumière sélectionnées et successives, pour conserver une même direction d'illumination L1 selon un angle α par rapport au sol 50 du chemin emprunté par la personne portant le dispositif 1 d'éclairage. La première illumination L1 est la combinaison de quatre faisceaux de lumière F provenant de quatre premières sources de lumière 5 activées. La direction d'illumination L1 a été mémorisée selon une position initiale du poignet suite à l'action manuelle du bouton-poussoir 40 de la figure 2 au moment de l'utilisation du dispositif 1 d'éclairage.In the present case, for the generation of a first illumination L1, there are for example four first light sources 5 activated by the control unit 2 and shown in gray on the figure 2 , and defining a first illuminated sector. The other first light sources 5 are inactive. However, during a movement of the person's wrist at an angle θ, another selection and activation of successive first light sources 5 is carried out by the control unit 2, for example four other first selected and successive light sources, to maintain the same direction of illumination L1 at an angle α with respect to the ground 50 of the path taken by the person wearing the lighting device 1. The first illumination L1 is the combination of four light beams F from four activated first light sources 5. The direction of illumination L1 was memorized according to an initial position of the wrist following the manual action of the push-button 40 of the figure 2 when using the lighting device 1.

Si utilisées, les secondes sources de lumière 6 sont aussi disposées sur ou en partie dans la lunette 10 de montre de forme annulaire ou circulaire. Il est prévu plusieurs secondes sources de lumière 6 disposées sur une portion de cercle de la périphérie de la lunette en étant de préférence régulièrement espacées l'une de l'autre. Les secondes sources de lumière 6 peuvent être disposées sur une portion de cercle pouvant aller jusqu'à 180° entre 6 h et minuit. Chaque seconde source de lumière 6 est reliée électriquement à l'unité de contrôle 2 disposée dans le boîtier de montre pour pouvoir être activée en fonction de mesures du capteur de mouvement 3, 4, qui est aussi disposé dans le boîtier de la montre. Chaque seconde source de lumière 6 peut générer une fois activée un faisceau de lumière se dirigeant radialement vers l'extérieur du boîtier de montre, c'est-à-dire sensiblement dans une direction parallèle au cadran de montre et perpendiculairement à la carrure du boîtier. Ainsi chaque seconde source de lumière 6 génère un faisceau de lumière d'orientation différente d'une autre seconde source de lumière activée. Le nombre de secondes sources de lumière 6 peut être égal au nombre des premières sources de lumière 5 afin de générer une seconde illumination L2 opposée à la première illumination L1.If used, the second light sources 6 are also disposed on or in part in the watch bezel 10 of annular or circular shape. Several second light sources 6 are provided, arranged on a portion of a circle of the periphery of the bezel, preferably being regularly spaced from one another. The second light sources 6 can be placed on a portion of a circle which can range up to 180 ° between 6 a.m. and midnight. Each second light source 6 is electrically connected to the control unit 2 arranged in the watch case so as to be able to be activated according to measurements from the movement sensor 3, 4, which is also arranged in the watch case. Each second light source 6 can generate, once activated, a beam of light directed radially towards the outside of the watch case, that is to say substantially in a direction parallel to the dial. watch and perpendicular to the middle of the case. Thus each second light source 6 generates a beam of light with a different orientation from another activated second light source. The number of second light sources 6 may be equal to the number of first light sources 5 in order to generate a second illumination L2 opposite to the first illumination L1.

Dans le cas présent, pour la génération de la seconde illumination L2, il est prévu par exemple quatre secondes sources de lumière 6 activées par l'unité de contrôle 2 et montrées en gris sur la figure 2 et définissant un second secteur illuminé opposé au premier secteur illuminé. Les autres secondes sources de lumière 6 sont inactives. Cependant lors d'un mouvement du poignet de la personne selon un angle θ, une autre sélection et activation de secondes sources de lumière 6 successives est effectuée par l'unité de contrôle 2, par exemple quatre autres secondes sources de lumière sélectionnées et successives, pour conserver une même direction d'illumination L2 selon un angle α par rapport au sol 50 du chemin emprunté par la personne portant le dispositif 1 d'éclairage. La seconde illumination L2 est la combinaison de quatre faisceaux de lumière provenant de quatre secondes sources de lumière 6 activées. La direction d'illumination L2 a été mémorisée selon une position initiale du poignet suite à l'action manuelle du bouton-poussoir 40 au moment de l'utilisation du dispositif 1 d'éclairage. La première illumination L1 peut être de couleur blanche, alors que la seconde illumination L2 peut être de couleur rouge par exemple.In the present case, for the generation of the second illumination L2, there are for example four second light sources 6 activated by the control unit 2 and shown in gray on the figure 2 and defining a second illuminated sector opposite the first illuminated sector. The other second light sources 6 are inactive. However, during a movement of the person's wrist at an angle θ, another selection and activation of successive second light sources 6 is carried out by the control unit 2, for example four other selected and successive second light sources, to maintain the same direction of illumination L2 at an angle α with respect to the ground 50 of the path taken by the person wearing the lighting device 1. The second illumination L2 is the combination of four light beams from four activated second light sources 6. The direction of illumination L2 has been memorized according to an initial position of the wrist following the manual action of the push-button 40 at the time of use of the lighting device 1. The first illumination L1 may be white in color, while the second illumination L2 may be red for example.

Il est à noter qu'il peut aussi être envisagé de n'avoir que des premières sources de lumière bicolores sur toute la périphérie de la lunette 10. Dans ces conditions, chaque première source de lumière 5 comprend deux diodes électroluminescentes montées tête-bêche. De cette manière, l'unité de contrôle 2 peut activer sur un premier secteur illuminé des premières sources de lumière 5 générant un faisceau lumineux de couleur blanche, et sur un second secteur illuminé d'autres premières sources de lumière 5 générant un faisceau lumineux de couleur rouge.It should be noted that it can also be envisaged to have only first two-color light sources over the entire periphery of the bezel 10. Under these conditions, each first light source 5 comprises two light-emitting diodes mounted head to tail. In this way, the control unit 2 can activate on a first illuminated sector first light sources 5 generating a colored light beam. white, and on a second illuminated sector other first light sources 5 generating a light beam of red color.

Selon la figure 3, les premières sources de lumière 5 peuvent être disposées sur tout le pourtour de la lunette 10 en étant en partie dans des cavités de la lunette 10. Il peut aussi être imaginé s'il est utilisé également des secondes sources de lumière de les placer sur tout le pourtour de la lunette 10 en dessus ou en dessous des premières sources de lumière 5 et de manière coaxiale. Une connexion électrique de chaque seconde source de lumière à l'unité de contrôle 2 peut être effectuée par l'intermédiaire de la plaque à circuit imprimé flexible 15, qui est agencée pour passer en dessous du cadran 16.According to figure 3 , the first light sources 5 can be arranged around the entire periphery of the bezel 10 while being partly in cavities of the bezel 10. It can also be imagined if it is also used second light sources to place them on. all around the bezel 10 above or below the first light sources 5 and coaxially. An electrical connection from every second light source to the control unit 2 can be made through the flexible printed circuit board 15, which is arranged to pass below the dial 16.

La figure 4 montre schématiquement un dispositif 1 d'éclairage actif portable sous la forme d'une montre-bracelet portée au poignet d'une personne pour éclairer le chemin emprunté par la personne. Dans ce cas de figure, la montre-bracelet est portée au poignet du bras B gauche, mais il peut être envisageable de réaliser une même montre-bracelet pour être portée au poignet du bras droit. On remarque que lors du mouvement du bras B avec le poignet de bas en haut selon la direction D, les premières illuminations L1 et L2, initialement calibrées au début de l'utilisation du dispositif 1 d'éclairage, restent toujours dans la même direction d'illumination vers l'avant pour la première illumination L1 et vers l'arrière pour la seconde illumination L2. Cela permet donc de bien éclairer le chemin emprunté par la personne portant le dispositif 1 d'éclairage lors d'une marche ou d'une course à pieds sur un chemin ou une route empruntée.The figure 4 schematically shows a portable active lighting device 1 in the form of a wristwatch worn on the wrist of a person to illuminate the path taken by the person. In this scenario, the wristwatch is worn on the wrist of the left arm B, but it may be possible to make the same wristwatch to be worn on the wrist of the right arm. It is noted that during the movement of the arm B with the wrist from bottom to top in direction D, the first illuminations L1 and L2, initially calibrated at the start of the use of the lighting device 1, always remain in the same direction d illumination towards the front for the first illumination L1 and towards the rear for the second illumination L2. This therefore makes it possible to properly illuminate the path taken by the person wearing the lighting device 1 when walking or running on a path or a route taken.

Il est à noter que les premières sources de lumière 5, voire des secondes sources de lumière 6 peuvent être placées sur une paroi extérieure de la carrure 12 de montre en figure 3 ou dans des cavités extérieures de la carrure 12, plutôt que sur ou dans la lunette 10. L'agencement des sources de lumière peut être identique à celui décrit ci-dessus en référence aux figures 2 et 3.It should be noted that the first light sources 5, or even the second light sources 6 can be placed on an outer wall of the watchband 12 in figure 3 or in exterior cavities of the middle part 12, rather than on or in the bezel 10. The arrangement of the light sources may be identical to that described above with reference to figures 2 and 3 .

Il est encore à noter que la forme du boîtier peut être différente d'une forme générale cylindrique, c'est-à-dire circulaire en vue de dessus. Il peut être de forme elliptique en vue de dessus ou rectangulaire ou autre. Dans ces conditions, les sources de lumière doivent être bien orientées par exemple sur un bord de la carrure ou sur une paroi extérieure de la carrure de manière à permettre une sélection de sources de lumière à activer quelque-soit le mouvement du poignet pour avoir toujours une illumination uniforme vers l'avant sans variation.It should also be noted that the shape of the case may be different from a generally cylindrical shape, that is to say circular in top view. It can be elliptical in top view or rectangular or the like. Under these conditions, the light sources must be well oriented, for example on an edge of the middle part or on an outer wall of the middle part so as to allow a selection of light sources to be activated whatever the movement of the wrist to always have uniform illumination forward without variation.

Le dispositif d'éclairage peut aussi être un bracelet à composants électroniques, où les premières sources de lumière, voire les secondes sources de lumière peuvent être montées sur la tranche latérale du bracelet. Les sources de lumière doivent aussi être bien orientées pour la génération d'au moins la première illumination vers l'avant sans variation.The lighting device can also be a bracelet with electronic components, where the first light sources, or even the second light sources, can be mounted on the side edge of the bracelet. The light sources must also be properly oriented for the generation of at least the first forward illumination without variation.

A partir de la description qui vient d'être faite, plusieurs variantes de réalisation d'un dispositif d'éclairage actif portable au poignet d'une personne sont possibles sans sortir du cadre de l'invention définie par les revendications suivantes.From the description which has just been given, several variant embodiments of an active lighting device portable to the wrist of a person are possible without departing from the scope of the invention defined by the following claims.
