Description

Dispositif lumineux comprenant une base, un projecteur et un bras connecté entre ladite base et ledit projecteur  Luminous device comprising a base, a projector and an arm connected between said base and said projector
Domaine de l'invention Field of the invention
La présente invention concerne le domaine des dispositifs d'éclairage et, plus spécifiquement, un dispositif lumineux comprenant une base permettant de fixer ledit dispositif lumineux sur un support, un projecteur pourvu d'au moins une source lumineuse et un bras connecté à l'une de ses extrémités sur la base à l'aide d'un premier élément de fixation, le projecteur étant fixé sur ledit bras à l'aide d'un deuxième élément de fixation. The present invention relates to the field of lighting devices and, more specifically, a light device comprising a base for fixing said light device on a support, a projector provided with at least one light source and an arm connected to one from its ends to the base with a first fastener, the projector being attached to said arm with a second fastener.
Etat de la technique State of the art
De nos jours, il est connu d'utiliser des dispositifs lumineux comprenant un projecteur muni d'au moins une source lumineuse, telle qu'une diode électroluminescente (DEL) et une base permettant de fixer ledit dispositif lumineux sur un support. Le projecteur est connecté à la base au moyen d'un bras, ayant par exemple la forme d'un U et d'un premier élément de fixation. Le bras est connecté à la base à l'aide du premier élément de fixation de façon à permettre au bras d'être mobile en rotation par rapport à la base autour d'un premier axe de rotation. Le projecteur est connecté au bras à l'aide d'un deuxième élément de fixation, le projecteur étant mobile en rotation par rapport au bras autour d'un deuxième axe de rotation. La base permet de fixer ledit dispositif lumineux sur un support, tel qu'un mur ou une structure porteuse sur laquelle plusieurs dispositifs lumineux peuvent être fixés les uns à côté des autres. La base est connectée, d'une part, à une source d'énergie électrique permettant d'acheminer ladite énergie électrique en direction de la source lumineuse du projecteur et, d'autre part, à un système de contrôle adapté pour générer des commandes concernant la gestion de l'utilisation du dispositif lumineux. Dans le domaine du spectacle, et plus particulièrement dans les représentations théâtrales ou les spectacles musicaux, les dispositifs lumineux représentent une part non négligeable du décor. En effet, les dispositifs lumineux sont utilisés dans le but de compléter l'image visuelle offerte aux spectateurs en générant des effets lumineux particuliers. Lors de l'utilisation normale des dispositifs lumineux, il est possible de matérialiser les faisceaux lumineux obtenus grâce à la source lumineuse et ce, à l'aide d'une fumée de type « brouillard ». Ce brouillard forme le support sur lequel les différents faisceaux lumineux sont projetés et rendus visibles pour les spectateurs. Nowadays, it is known to use light devices comprising a projector provided with at least one light source, such as a light-emitting diode (LED) and a base for fixing said light device on a support. The projector is connected to the base by means of an arm, having for example the shape of a U and a first fixing element. The arm is connected to the base with the first attachment member so as to allow the arm to be rotatable relative to the base about a first axis of rotation. The projector is connected to the arm with a second fastener, the projector being rotatable relative to the arm about a second axis of rotation. The base makes it possible to fix said luminous device on a support, such as a wall or a supporting structure on which several luminous devices can be fixed next to each other. The base is connected, on the one hand, to a source of electrical energy for conveying said electrical energy towards the light source of the projector and, on the other hand, to a control system adapted to generate commands concerning the management of the use of the luminous device. In the field of the spectacle, and more particularly in the theatrical representations or the musical spectacles, the luminous devices represent a not insignificant part of the decoration. Indeed, the luminous devices are used in order to complete the visual image offered to the spectators by generating particular luminous effects. During the normal use of the light devices, it is possible to materialize the light beams obtained by means of the light source and this, using a smoke type "fog". This fog forms the support on which the various light beams are projected and made visible to the spectators.
Les utilisateurs de dispositifs lumineux agencent un nombre déterminé de tels dispositifs lumineux afin de créer une structure permettant d'obtenir des effets visuels innovants. Ainsi, les dispositifs lumineux doivent être facilement juxtaposables et ajustables afin de s'assembler sans difficulté quelle que soit la structure finale à obtenir. De plus, en vue d'une utilisation optimale, les dispositifs lumineux assemblés doivent couvrir une surface donnée en réduisant au maximum l'espace libre entre deux dispositifs lumineux adjacents. Dans l'art antérieur, la demande de brevet DE19750368 divulgue un dispositif lumineux comprenant une sphère lumineuse, un bras de support et une base. Compte tenu de la dimension extérieure du bras de support, la juxtaposition de deux dispositifs lumineux nécessite la présence d'un espace libre entre deux bases adjacentes. L'occupation de la surface concernée n'est donc pas optimale. Users of light devices arrange a fixed number of such light devices to create a structure for obtaining innovative visual effects. Thus, the light devices must be easily juxtaposed and adjustable to assemble without difficulty regardless of the final structure to obtain. In addition, for optimum use, the assembled light devices must cover a given surface by minimizing the free space between two adjacent light devices. In the prior art, the patent application DE19750368 discloses a light device comprising a light sphere, a support arm and a base. Given the external dimension of the support arm, the juxtaposition of two light devices requires the presence of a free space between two adjacent bases. The occupation of the surface concerned is therefore not optimal.
Par ailleurs, afin de garantir de multiples possibilités d'illumination, les dispositifs lumineux doivent être de structure simple avec un nombre réduit de pièces mécaniques afin de garantir une fiabilité au cours du temps. Dans l'art antérieur, la demande de brevet US2004/0070984 divulgue un dispositif lumineux comprenant un bras de support, une sphère lumineuse et une base. Le bras de support est mobile en rotation par rapport à la base et la sphère lumineuse est mobile en rotation par rapport au bras de support. Cependant, la rotation de la sphère lumineuse par rapport au bras de support est réalisée au moyen d'une seule pièce de connexion. Ainsi, compte tenu des mouvements sollicités par le dispositif lumineux, la pièce de connexion peut rapidement se détériorer et entraîner un dysfonctionnement du dispositif lumineux. Dans l'art antérieur, le brevet US8,201 ,974 divulgue un dispositif lumineux comprenant une pluralité de sources lumineuses, une base et un support rotatif permettant l'orientation des sources lumineuses selon deux axes de rotation perpendiculaires entre eux. Un tel dispositif lumineux est de structure complexe et onéreuse. Moreover, in order to guarantee multiple possibilities of illumination, the luminous devices must be of simple structure with a reduced number of mechanical parts in order to guarantee reliability over time. In the prior art, the patent application US2004 / 0070984 discloses a light device comprising a support arm, a light sphere and a base. The support arm is rotatable relative to the base and the light sphere is rotatable relative to the support arm. However, the rotation of the light sphere relative to the support arm is performed by means of a single connecting piece. Thus, given the movements urged by the light device, the connection piece can quickly deteriorate and cause a malfunction of the light device. In the prior art, US Pat. No. 8,201,974 discloses a light device comprising a plurality of light sources, a base and a rotatable support allowing the orientation of the light sources along two axes of rotation perpendicular to each other. Such a light device is complex and expensive structure.
Dans l'art antérieur, la demande US6,146,195 décrit également un dispositif lumineux comprenant une sphère lumineuse, deux bras de support et une base. La présence d'un deuxième bras de support entraîne la présence d'éléments de connexion additionnels qui représentent des points de faiblesse pour la fiabilité du dispositif lumineux au cours du temps. In the prior art, the application US6,146,195 also describes a light device comprising a light sphere, two support arms and a base. The presence of a second support arm results in the presence of additional connection elements which represent points of weakness for the reliability of the light device over time.
Les dispositifs lumineux doivent également permettre la diffusion de faisceaux lumineux sans limitation angulaire. The light devices must also allow the diffusion of light beams without angular limitation.
Au sein de l'art antérieur, dans un domaine éloigné relatif aux caméras de surveillance, la demande de brevet US2013/0147963 décrit un dispositif de surveillance comprenant une base, un bras et une caméra. La structure du bras est telle que la zone réservée à l'emplacement de la caméra est extrêmement réduite. Par conséquent, le mouvement de la caméra est limité au sein du dispositif de surveillance. In the prior art, in a remote field relating to surveillance cameras, patent application US2013 / 0147963 describes a monitoring device comprising a base, an arm and a camera. The structure of the arm is such that the area reserved for the location of the camera is extremely small. Therefore, the movement of the camera is limited within the monitoring device.
Dans l'art antérieur, dans un domaine éloigné relatif aux caméras de surveillance, la demande de brevet US 201 1/0184249 décrit un dispositif de surveillance de type PTZ (en anglais, pan-tilt-zoom) comprenant une base, un bras et une caméra. Comme connu par l'homme du métier, au sein de ce type de dispositif de surveillance, la caméra est mobile en rotation autour de la base. Cependant, la caméra est mobile par rapport au bras selon un degré d'inclinaison déterminé. Par conséquent, l'amplitude angulaire de la caméra par rapport au bras est relativement limitée. In the prior art, in a remote field relating to surveillance cameras, patent application US 201 1/0184249 describes a PTZ (pan-tilt-zoom) surveillance device comprising a base, an arm and a camera. As known to those skilled in the art, within this type of surveillance device, the camera is rotatable around the base. However, the camera is movable relative to the arm according to a determined degree of inclination. Therefore, the angular amplitude of the camera relative to the arm is relatively limited.
Ainsi, il apparaît que les dispositifs lumineux dans l'art antérieur ne permettent pas d'optimiser la surface occupée ou de garantir une amplitude de mouvement illimitée pour la source lumineuse ainsi qu'une fiabilité du dispositif lumineux au cours du temps. Au regard des observations ci-dessus, le but de la présente invention consiste à proposer un dispositif lumineux au sein duquel le projecteur du dispositif lumineux dispose d'une liberté de mouvements améliorée de sorte qu'un premier dispositif lumineux peut facilement être positionné à faible distance d'autres dispositifs lumineux afin d'obtenir un système lumineux comprenant plusieurs dispositifs lumineux. Thus, it appears that the light devices in the prior art do not optimize the occupied area or guarantee an unlimited range of motion for the light source and reliability of the light device over time. In view of the observations above, the object of the present invention is to provide a light device in which the projector of the light device has an improved freedom of movement so that a first light device can easily be positioned at low distance from other luminous devices in order to obtain a luminous system comprising several luminous devices.

De plus, la taille et la forme de la base sont définies pour que les extrémités de ladite base soient contenues à l'intérieur du même volume cylindrique, lors d'une rotation du projecteur par rapport au bras autour du premier axe de rotation.

La présente invention concerne un dispositif lumineux, tout particulièrement adapté dans le but d'être utilisé au sein d'un ensemble lumineux de plusieurs dispositifs lumineux, lesdits dispositifs lumineux étant positionnés les uns à côté des autres. The present invention relates to a light device, particularly adapted for the purpose of being used in a light assembly of several light devices, said light devices being positioned next to each other.
La figure 1 décrit le mode de réalisation d'un dispositif lumineux 10 selon l'invention. Le dispositif lumineux 10 comprend une base 1 adaptée pour permettre le positionnement et la fixation du dispositif lumineux 10 sur un support. Le support peut se présenter sous toute forme adaptée de support, par exemple un mur. Lors d'une utilisation normale, la base 1 est souvent fixée sur une structure porteuse spécifique. Une telle structure porteuse permet de fixer ensemble plusieurs dispositifs lumineux 10, à une distance minimale les uns à côté des autres, afin d'obtenir un ensemble lumineux de dispositifs lumineux fournissant des effets visuels optimaux. Figure 1 describes the embodiment of a light device 10 according to the invention. The light device 10 comprises a base 1 adapted to allow the positioning and fixing of the light device 10 on a support. The support may be in any suitable form of support, for example a wall. In normal use, the base 1 is often attached to a specific supporting structure. Such a carrier structure makes it possible to fix together several light devices 10, at a minimum distance next to each other, in order to obtain a luminous assembly of light devices providing optimal visual effects.
La base 1 est pourvue d'au moins un connecteur permettant la connexion avec une source d'énergie électrique. De plus, la base 1 est pourvue d'un autre connecteur permettant la réception des signaux de contrôle associés aux commandes de contrôle et le fonctionnement optimal du dispositif lumineux 10 selon les préférences d'un utilisateur. Les commandes de contrôle permettent d'obtenir la rotation d'un bras 2 et d'un projecteur 4 décrits ci-dessous. The base 1 is provided with at least one connector for connection with a source of electrical energy. In addition, the base 1 is provided with another connector for receiving the control signals associated with the control commands and the optimal operation of the light device 10 according to the preferences of a user. The control commands make it possible to obtain the rotation of an arm 2 and a projector 4 described below.
En effet, le dispositif 10 comprend un bras 2 connecté, à son extrémité inférieure, à la base 1 grâce à un premier élément de fixation 3. Le premier élément de fixation 3 permet au bras 2 de rester mobile en rotation par rapport à la base 1 , autour d'un premier axe de rotation I. Le premier axe de rotation I , montré sur la figure 1 , est un axe vertical situé au centre du dispositif lumineux 10. Lors d'une rotation autour du premier axe de rotation I, le bras 2 pivote librement par rapport à la base 1. Selon la présente invention, l'élément de fixation 3 permet la rotation, sans limite, du bras 2 par rapport à la base 1. Ainsi, le bras 2 peut pivoter, vers une première ou une deuxième direction, selon un angle compris entre 0 et 360°, et ce autant de fois que nécessaire pour une utilisation optimale. Ainsi, le bras 2 peut produire un mouvement circulaire de manière répétée et continue. Le mouvement de rotation étant sans limite, la manipulation du bras 2 est donc facilitée, ce qui permet une flexibilité d'utilisation améliorée pour l'utilisateur. En effet, la manipulation du bras 2 permet d'orienter ledit bras 2 selon n'importe quel angle en effectuant un mouvement rotatif minimal. L'élément de fixation 3 est adapté à la transmission, d'une part, de l'énergie électrique de la base 1 vers le bras 2 et, d'autre part, à la transmission des signaux permettant de contrôler les mouvements et l'utilisation de la source lumineuse du dispositif 10. Indeed, the device 10 comprises an arm 2 connected at its lower end to the base 1 by means of a first fastening element 3. The first fastening element 3 allows the arm 2 to remain rotatable relative to the base 1, about a first axis of rotation I. The first axis of rotation I, shown in Figure 1, is a vertical axis located in the center of the light device 10. When rotating about the first axis of rotation I, the arm 2 pivots freely relative to the base 1. According to the present invention, the fastening element 3 allows the rotation, without limit, of the arm 2 relative to the base 1. Thus, the arm 2 can pivot, towards a first or a second direction, at an angle between 0 and 360 °, and as many times as necessary for optimal use. Thus, the arm 2 can produce a circular motion repeatedly and continuously. The rotational movement being without limit, the manipulation of the arm 2 is facilitated, which allows an increased flexibility of use for the user. Indeed, the manipulation of the arm 2 can guide said arm 2 at any angle by performing a minimum rotational movement. The fixing element 3 is adapted to the transmission, on the one hand, of the electrical energy from the base 1 to the arm 2 and, on the other hand, to the transmission of the signals making it possible to control the movements and the use of the light source of the device 10.
Le dispositif lumineux 10 comprend un projecteur 4 fixé au bras 2 à l'aide d'un deuxième élément de fixation 5 et d'un troisième élément de fixation 6. Le deuxième élément de fixation 5 permet au projecteur 4 de pivoter librement autour d'un deuxième axe de rotation II, selon un angle compris entre 0 et 360°, et ce autant de fois que nécessaire pour une utilisation optimale. Ainsi, le projecteur 4 peut produire un mouvement circulaire de manière répétée et continue. Le mouvement de rotation étant sans limite, la manipulation du projecteur 4 est donc facilitée, ce qui permet une flexibilité d'utilisation améliorée pour l'utilisateur. En effet, la manipulation du projecteur 4 permet d'orienter ledit projecteur 4 selon n'importe quel angle en effectuant un mouvement rotatif minimal. Le deuxième axe de rotation II, montré sur la figure 1 , est un axe de rotation horizontal essentiellement perpendiculaire au premier axe de rotation I. Dans le mode de réalisation selon la figure 1 , le bras 2 se présente essentiellement sous la forme d'un « U ». Le projecteur 4 est connecté aux deux éléments longitudinaux du « U » grâce à un deuxième élément de fixation 5 et à un troisième élément de fixation 6. Les éléments de fixation 5 et 6 sont positionnés pour permettre, en combinaison, la rotation du projecteur 4 par rapport au bras 2. Le deuxième élément de fixation 5 et le troisième élément de fixation 6 sont du même type que le premier élément de fixation 3. En d'autres termes, le deuxième élément de fixation 5 et le troisième élément de fixation 6 sont adaptés pour permettre une libre rotation du projecteur 4 par rapport au bras 2. Le projecteur 4 peut pivoter, sans limite, quel que soit le sens de rotation. De plus, au moins le deuxième élément de fixation 5 ou le troisième élément de fixation 6 peut être adapté pour transmettre l'énergie électrique et les commandes du bras 2 vers le projecteur 4 et ce, afin de permettre le fonctionnement optimal de la source lumineuse du projecteur 4. The luminous device 10 comprises a projector 4 fixed to the arm 2 by means of a second fastening element 5 and a third fastening element 6. The second fastening element 5 allows the projector 4 to pivot freely around the projector. a second axis of rotation II, at an angle between 0 and 360 °, and as many times as necessary for optimal use. Thus, the projector 4 can produce a circular motion repeatedly and continuously. The rotational movement being limitless, the manipulation of the projector 4 is thus facilitated, which allows an increased flexibility of use for the user. Indeed, the manipulation of the projector 4 allows to orient said projector 4 at any angle by performing a minimum rotational movement. The second axis of rotation II, shown in Figure 1, is a horizontal axis of rotation substantially perpendicular to the first axis of rotation I. In the embodiment according to Figure 1, the arm 2 is essentially in the form of a "U". The projector 4 is connected to the two longitudinal elements of the "U" through a second fastening element 5 and a third fastening element 6. The fastening elements 5 and 6 are positioned to allow, in combination, the rotation of the projector 4 relative to the arm 2. The second fastener 5 and the third fastener 6 are of the same type as the first fastener 3. In other words, the second fastener 5 and the third fastener 6 are adapted to allow free rotation of the projector 4 relative to the arm 2. The projector 4 can rotate, without limit, whatever the direction of rotation. In addition, at least the second fastening element 5 or the third fastening element 6 can be adapted to transmit the electrical energy and the controls of the arm 2 towards the projector 4 and this, in order to allow the optimal operation of the light source of the projector 4.
Le projecteur 4 est pourvu, en son sein, d'au moins une source lumineuse qui émet un faisceau lumineux vers l'extérieur du projecteur 4. Une telle source lumineuse comprend, par exemple, une diode électroluminescente (DEL). La conception la plus adaptée pour une utilisation au sein d'un dispositif lumineux 10 selon l'invention est celle visant à utiliser une DEL fixée sur un circuit imprimé. La DEL reçoit des instructions relatives à l'utilisation des DEL, grâce à ce circuit imprimé, ledit circuit imprimé étant adapté pour recevoir des commandes visant à une utilisation optimale desdites DEL. Tout type de DEL peut être utilisé au sein du dispositif lumineux 10 selon la présente invention, comme par exemple une DEL multicolore associée à quatre couleurs : rouge, vert, bleu et blanc. La présence de ces quatre couleurs permet de définir une multitude de combinaisons de couleurs pour la source lumineuse. Les DEL multicolores sont utilisées, au sein de l'invention, en combinaison avec un élément optique, tel qu'un collimateur, dans le but de diriger le faisceau lumineux issu de la source lumineuse vers l'extérieur du projecteur 4. L'utilisation d'une structure composée de DEL fixées sur un circuit imprimé et d'un collimateur est décrite en détail au sein de la demande de brevet français FR2988474 au nom du même déposant. The projector 4 is provided, within it, with at least one light source which emits a light beam towards the outside of the projector 4. Such a light source comprises, for example, a light-emitting diode (LED). The most suitable design for use within a light device 10 according to the invention is that to use an LED fixed on a printed circuit. The LED receives instructions relating to the use of the LEDs, thanks to this printed circuit, said printed circuit being adapted to receive commands aiming at an optimal use of said LEDs. Any type of LED can be used within the light device 10 according to the present invention, such as for example a multicolored LED associated with four colors: red, green, blue and white. The presence of these four colors makes it possible to define a multitude of color combinations for the light source. The multicolored LEDs are used, in the invention, in combination with an optical element, such as a collimator, for the purpose of directing the light beam coming from the light source towards the outside of the projector 4. The use a structure composed of LEDs fixed on a printed circuit and a collimator is described in detail in the French patent application FR2988474 in the name of the same applicant.
Le dispositif lumineux 10 selon l'invention produit un faisceau lumineux offrant une couleur et une intensité qui dépendent des commandes transmises audit dispositif lumineux 10. Lors d'une utilisation normale, le dispositif lumineux 10 peut être utilisé en présence d'un écran de fumée de type « brouillard ». Lorsque le faisceau lumineux éclaire ledit écran de fumée, ledit faisceau lumineux se matérialise sur ledit écran de fumée. The light device 10 according to the invention produces a light beam having a color and an intensity depending on the commands transmitted to said light device 10. During normal use, the light device 10 can be used in the presence of a smoke screen of type "fog". When the light beam illuminates said smoke screen, said light beam materializes on said smoke screen.
La figure 2 montre une vue latérale du dispositif lumineux 10 selon la figure 1 . Sur la figure 2, le bras 2 positionné sur la base 1 possède des dimensions extérieures similaires à celle de la base 1. Comme montré sur la figure 2, le projecteur 4 se présente essentiellement sous la forme d'une sphère, le deuxième axe de rotation II étant essentiellement identique à l'axe de symétrie de ladite sphère, dans un plan parallèle au plan horizontal de la base 1 . Un faisceau lumineux 20, obtenu à l'aide d'une source lumineuse, est schématiquement représenté à l'aide de lignes en pointillées. Le bras 2 peut pivoter librement par rapport à la base autour du premier axe de rotation I selon les deux sens montrés par la flèche. FIG. 2 shows a side view of the light device 10 according to FIG. In FIG. 2, the arm 2 positioned on the base 1 has external dimensions similar to that of the base 1. As shown in FIG. 2, the projector 4 is essentially in the form of a sphere, the second axis of rotation II being essentially identical to the axis of symmetry of said sphere, in a plane parallel to the horizontal plane of the base 1. A light beam 20, obtained with the aid of a light source, is schematically represented by means of lines dashed. The arm 2 can pivot freely relative to the base around the first axis of rotation I in both directions shown by the arrow.
La figure 3 représente une vue de dessus du dispositif lumineux 10 selon les figures 1 et 2. La figure 3 montre le bras 2 et le projecteur 4. La base 1 , couverte par le bras 2, n'est pas visible sur la figure 3. FIG. 3 represents a view from above of the light device 10 according to FIGS. 1 and 2. FIG. 3 shows the arm 2 and the projector 4. The base 1, covered by the arm 2, is not visible in FIG. 3 .
Ainsi, comme montré sur les figures 1 , 2 et 3, le projecteur 4 peut pivoter par rapport au bras 2 et l'ensemble formé du bras 2 et du projecteur 4 peut pivoter librement par rapport à la base 1 . Le dispositif lumineux 10 selon l'invention est tel que, lors d'une rotation du bras 2 autour du premier axe de rotation I, les extrémités de la base 1 sont contenues dans un volume cylindrique défini par les extrémités libres du bras 2 lors d'une rotation du bras 2 autour du premier axe de rotation I. De façon simultanée, lors d'une rotation du projecteur 4 par rapport au bras 2, autour du deuxième axe de rotation II, les extrémités du projecteur 4 sont contenues dans le même volume cylindrique. Thus, as shown in FIGS. 1, 2 and 3, the projector 4 can pivot relative to the arm 2 and the assembly formed by the arm 2 and the projector 4 can pivot freely relative to the base 1. The light device 10 according to the invention is such that, during a rotation of the arm 2 around the first axis of rotation I, the ends of the base 1 are contained in a cylindrical volume defined by the free ends of the arm 2 when the a rotation of the arm 2 about the first axis of rotation I. Simultaneously, during a rotation of the projector 4 relative to the arm 2, around the second axis of rotation II, the ends of the projector 4 are contained in the same cylindrical volume.
Ainsi, le volume cylindrique est défini de telle sorte que ledit volume cylindrique contient entièrement la base 1 , le bras 2 et le projecteur 4 et ce, de manière compacte. En effet, la base 1 définit les dimensions de la base du volume cylindrique à une première extrémité. Les dimensions extérieures du bras 2 définissent les dimensions de la paroi du volume cylindrique. Les dimensions du projecteur 4 définissent l'emplacement de la base du volume cylindrique à une deuxième extrémité. Thus, the cylindrical volume is defined such that said cylindrical volume completely contains the base 1, the arm 2 and the projector 4 and in a compact manner. Indeed, the base 1 defines the dimensions of the base of the cylindrical volume at a first end. The outer dimensions of the arm 2 define the dimensions of the wall of the cylindrical volume. The dimensions of the projector 4 define the location of the base of the cylindrical volume at a second end.
L'encombrement du dispositif lumineux 10 au sein du volume cylindrique est défini de telle sorte que le dispositif lumineux 10 comprend un projecteur 4 qui contient un élément optique dont les dimensions sont les plus grandes possibles en combinaison avec une base 1 dont les dimensions sont les plus petites possibles. The size of the light device 10 within the cylindrical volume is defined so that the light device 10 comprises a projector 4 which contains an optical element whose dimensions are the largest possible in combination with a base 1 whose dimensions are the smaller possible.
Grâce aux caractéristiques techniques du dispositif lumineux 10 selon l'invention, un premier dispositif lumineux 10 peut être positionné à une faible distance d'un deuxième dispositif lumineux 10, dans la mesure où la rotation du bras 2 autour du premier axe de rotation I et la rotation du projecteur 4 autour du deuxième axe de rotation II ne gênent pas la libre rotation du bras 2 et du projecteur 4 du deuxième dispositif lumineux 10. Thanks to the technical characteristics of the light device 10 according to the invention, a first light device 10 can be positioned at a small distance from a second light device 10, insofar as the rotation of the arm 2 around the first axis of rotation I and the rotation of the projector 4 around the second axis of rotation II does not interfere with the free rotation of the arm 2 and the projector 4 of the second light device 10.
La figure 4 représente un premier ensemble lumineux de quatre dispositifs lumineux 10 selon l'invention. Les quatre dispositifs lumineux 10 selon la disposition telle que décrite sur la figure 4 forment, en combinaison, un carré. La figure 4 montre que les différents dispositifs lumineux 10 peuvent être positionnés, de manière très proche, les uns des autres sans que les différentes rotations exercées par les bras 2 et des projecteurs 4 des différents dispositifs lumineux 10 n'entravent les rotations des bras 2 et des projecteurs 4 des dispositifs voisins. FIG. 4 represents a first luminous assembly of four luminous devices 10 according to the invention. The four light devices 10 according to the arrangement as described in Figure 4 form, in combination, a square. FIG. 4 shows that the various luminous devices 10 can be positioned, very closely, from each other without the different rotations exerted by the arms 2 and the projectors 4 of the different luminous devices 10 hindering the rotations of the arms 2 and projectors 4 of neighboring devices.
Selon la figure 4, les bras 2 et les projecteurs 4 sont positionnés afin de permettre aux faisceaux lumineux 20 de former, en combinaison, un effet visuel divergent. La figure 5 montre les dispositifs lumineux 10 selon la figure 4, avec les bras 2 et les projecteurs 4 positionnés de telle manière que les différents faisceaux lumineux 20 forment, en combinaison, un effet visuel convergent. According to Figure 4, the arms 2 and the projectors 4 are positioned to allow the light beams 20 to form, in combination, a divergent visual effect. FIG. 5 shows the luminous devices 10 according to FIG. 4, with the arms 2 and the projectors 4 positioned in such a way that the different light beams 20 form, in combination, a convergent visual effect.
La figure 6 représente un ensemble lumineux de sept dispositifs lumineux 10 selon l'invention. Selon la figure 6, les différents dispositifs lumineux 10 peuvent être positionnés de manière très proche les uns des autres, sans que les différentes rotations exercées par les bras 2 et des projecteurs 4 des différents dispositifs lumineux 10 n'entravent les rotations des bras 2 et des projecteurs 4 des dispositifs lumineux voisins 10. FIG. 6 represents a luminous assembly of seven light devices 10 according to the invention.
