Description

Dispositif d'éclairage formé à partir d'éléments lumineux et rampe d'éclairage formée par une pluralité de tels dispositifs d'éclairage.»  A lighting device formed from light elements and a lighting beam formed by a plurality of such lighting devices. '
La présente invention concerne un dispositif d'éclairage formé à partir d'éléments lumineux, d'un circuit d'alimentation pour alimenter lesdits éléments. The present invention relates to a lighting device formed from light elements, a power supply circuit for powering said elements.
La présente invention concerne aussi une rampe d'éclairage formée par une pluralité de tels dispositifs d'éclairage.  The present invention also relates to a lighting ramp formed by a plurality of such lighting devices.
De tels dispositifs sont bien connus surtout ceux qui utilisent des diodes LED comme éléments lumineux. Les diodes LED fournissent un éclairage puissant compte tenu de leur puissance électrique consommée. Dans de nombreuses applications, on souhaite un éclairage omnidirectionnel et intense alors que les diodes LED fournissent plutôt des flux lumineux très directionnels.  Such devices are well known especially those using LEDs as light elements. The LEDs provide powerful lighting considering their electrical power consumed. In many applications, omnidirectional and intense lighting is desired whereas LED diodes provide rather highly directional light flows.
Le but de l'invention est de fournir une lampe qui profite des qualités de rendement des diodes LED et qui éclaire d'une façon omnidirectionnelle tout en présentant la possibilité d'obtenir une grande intensité lumineuse.  The object of the invention is to provide a lamp which takes advantage of the performance qualities of LEDs and which illuminates in an omnidirectional manner while having the possibility of obtaining a high light intensity.
Pour cela, un dispositif du genre mentionné dans le préambule est remarquable en ce que lesdits éléments sont organisés en au moins un ensemble d'au moins un élément lumineux.  For this, a device of the kind mentioned in the preamble is remarkable in that said elements are organized in at least one set of at least one light element.
Conformément à un aspect de l'invention, le dispositif comporte une pluralité desdits ensembles disposés sur au moins une plaquette support et disposés de sorte à fournir un éclairage selon une couverture déterminée,  According to one aspect of the invention, the device comprises a plurality of said assemblies arranged on at least one support plate and arranged so as to provide lighting according to a determined coverage,
Ainsi en augmentant le nombre d'ensemble dirigés vers des directions différentes, on obtient un éclairage omnidirectionnel ou un éclairage présentant une couverture lumineuse donnée et aussi une luminosité pouvant être plus forte.  Thus by increasing the number of assemblies directed to different directions, one obtains an omnidirectional lighting or a lighting having a given light coverage and also a brightness that can be stronger.
Une application intéressante de l'invention est celle qui concerne l'éclairage des parkings qui nécessite une facilité de maintenance et aussi d'installation.  An interesting application of the invention is that concerning the lighting of car parks which requires ease of maintenance and also installation.
Pour la maintenance, l'invention propose un système d'enfichage des plaquettes en vue de faciliter leur remplacement en cas de défaillance. En ce qui concerne la facilité d'installation, le circuit d'alimentation est d'un type régulé pour ajuster la tension d'alimentation des éléments lumineux en palliant ainsi d'éventuelles baisses de tension dues à la longueur du câble d'alimentation destiné à alimenter la rampe. En effet, si on a affaire à une rampe de tels dispositifs, la tension accessible en bout de rampe est bien plus faible qu'en début. Il est à noter que le câble d'alimentation véhiculant de préférence une tension de faible valeur ne nécessite pas de précautions ou d'autorisation pour l'installation d'une telle rampe. For maintenance, the invention proposes a platelet insertion system to facilitate their replacement in case of failure. With regard to the ease of installation, the power supply circuit is of a controlled type to adjust the supply voltage of the light elements thus compensating for any voltage drops due to the length of the power supply cable. to feed the ramp. Indeed, if we are dealing with a ramp of such devices, the voltage accessible at the end of the ramp is much lower than at the beginning. It should be noted that the power cable carrying preferably a Low voltage value does not require any precautions or authorization for the installation of such a ramp.

Sur ces figures, les éléments communs portent tous les mêmes références sur toutes les figures. In these figures, the common elements all have the same references in all the figures.
A la figure 1, le dispositif d'éclairage représenté est formé d'une embase 5 de forme circulaire, par exemple. Au centre de cette embase, est fixée l'extrémité d'une tige filetée 7. A une certaine distance de l'embase 5 est fixée une plaque de soutien 10 traversée par cette tige filetée 7. Cette distance est déterminée par un écrou, non représenté, qui bloque le déplacement vertical de cette plaque de soutien 10. Sur cette plaque de soutien 10 sont disposées des facettes d'illumination Fl, F2, F3, F4 et F5. Sur ces facettes sont fixées des plaquettes support dont quelques-unes (PSI, PS2, ...) seulement sont référencées sur la figure pour éviter de la surcharger. Sur chacune de ces plaquettes est placé un ensemble El d'éléments lumineux Ll ...L20 comme cela est représenté à la figure 2. Le positionnement des facettes et même aussi desdites plaquettes permet de régler la direction et la répartition du rayonnement dans l'espace. In Figure 1, the lighting device shown is formed of a base 5 of circular shape, for example. In the center of this base, is fixed the end of a threaded rod 7. At a distance from the base 5 is fixed a support plate 10 through which this threaded rod 7. This distance is determined by a nut, no shown, which blocks the vertical displacement of the support plate 10. On this support plate 10 are arranged illumination facets Fl, F2, F3, F4 and F5. On these facets are fixed support plates some of which (PSI, PS2, ...) are only referenced on the figure to avoid overloading it. On each of these plates is placed a set E1 of luminous elements L1 ... L20 as shown in FIG. 2. The positioning of the facets and even also of said plates makes it possible to adjust the direction and distribution of the radiation in the space.
La figure 3 montre que les plaquettes support PSI sont amovibles en vue de faciliter leur remplacement. Pour cela, des connecteurs Cl, C2, C3, ... solidaires des plaquettes PSI sont prévues sur ces plaquettes et viennent en contact sur des prises PI, P2, P3 respectivement ménagées sur les facettes d'illumination (Fl, ...). Figure 3 shows that the PSI support pads are removable to facilitate their replacement. For this purpose, connectors C1, C2, C3,... Integral with the PSI plates are provided on these plates and come into contact with sockets P1, P2, P3 respectively formed on the illumination facets (F1,...). .
Le dispositif d'éclairage comporte un dôme de protection 20 fait en matière transparente telle que le polyméthacrylate de méthyle plus connu sous le nom commercial de « plexiglass ». Ce dôme 20 se présente sous la forme d'une demi-sphère dont la base repose sur la plaque de soutien 10. Pour centrer ce dôme, on a prévu des ergots 25, 26, 27, ...31 comme cela est représenté à la figure 4. Ces ergots sont disposés à la périphérie de la plaque de soutien 10. Un trou 40 au sommet de ce dôme permet de passer la tige filetée.7. Un autre trou 61 visible sur la figure 4 est ménagé dans la plaque de soutien 10 pour le passage d'un câble 63. Un écrou 43 maintient ce dôme 20 contre la plaque de soutien 10. The lighting device comprises a protective dome 20 made of transparent material such as polymethylmethacrylate better known under the trade name of "plexiglass". This dome 20 is in the form of a hemisphere whose base rests on the support plate 10. To center this dome, there are provided pins 25, 26, 27, ... 31 as shown in FIG. These lugs are arranged at the periphery of the support plate 10. A hole 40 at the top of this dome allows the threaded rod to be passed. Another hole 61 visible in FIG. 4 is formed in the support plate 10 for the passage of a cable 63. A nut 43 holds this dome 20 against the support plate 10.
Un circuit d'alimentation 60 est placé sous les facettes d'illumination F1...F5. Ce circuit est connecté au câble d'alimentation 63 qui passe dans le trou 61. Ce circuit est formé d'un transformateur 65 d'une électronique de commande 67 et d'un système d'accumulateur 69. Le transformateur est d'un type à régulation qui fournit, notamment pour l'éclairage, une tension déterminée pour une gamme de tension qui est appliquée à son entrée. L'accumulateur 69 préserve l'illumination lors d'une coupure de tension et peut ainsi fournir une tension de secours à au moins un élément lumineux. A supply circuit 60 is placed under the illumination facets F1 ... F5. This circuit is connected to the power cable 63 which passes through the hole 61. This circuit is formed by a transformer 65 of a control electronics 67 and an accumulator system 69. The transformer is of a type a regulation which provides, especially for lighting, a determined voltage for a voltage range which is applied to its input. The battery 69 preserves the illumination during a power failure and can thus provide a backup voltage to at least one light element.
Le montage du dispositif de l'invention basé sur une tige filetée permet un démontage facile qui, associé à la possibilité de changer facilement les plaquettes support (PSI etc.) offre une grande facilité pour la maintenance de ce dispositif. The mounting of the device of the invention based on a threaded rod allows easy disassembly which, associated with the possibility of easily changing the support plates (PSI etc.) offers great ease for the maintenance of this device.
D'une façon avantageuse, les dispositifs de l'invention sont bien adaptés à une configuration en rampe. Grâce à l'invention, il est possible de jouer sur la répartition de lumière en inclinant les différentes facettes Fl, F2,...; pour obtenir une répartition ou une couverture de l'illumination désirée de chaque dispositif. En outre, la régulation des tensions apportée par les transformateurs régulés permet d'obtenir des rampes de grande portée sans détérioration de l'intensité lumineuse en bout de ligne. La figure 6 montre la structure d'une telle rampe qui se compose d'une pluralité de dispositifs conformes à l'invention 100, 101,102, 103 qui sont tous reliés à un câble d'alimentation 63. Advantageously, the devices of the invention are well adapted to a ramp configuration. Thanks to the invention, it is possible to play on the light distribution by tilting the different facets Fl, F2, ...; to obtain a distribution or coverage of the desired illumination of each device. In addition, the regulation of the voltages brought by the regulated transformers makes it possible to obtain ramps of great range without deterioration of light intensity at the end of the line. FIG. 6 shows the structure of such a ramp which consists of a plurality of devices according to the invention 100, 101, 102, 103 which are all connected to a power cable 63.
Un domaine d'application de telle rampe est l'éclairage de parking Ceci est montré à la figure 7. Le parking est composée de deux travées : une première travée pour les véhicules VI, V2, ...,V5 et une deuxième travée pour les véhicules Vi l, VI 2, ...,V15. A chacune de ces travées est affectée d'une rampe. Une première rampe est affectée à la première travée et se compose des dispositifs d'éclairage 111, 112, 113, 114 et 115. Ces dispositifs sont alimentés par le câble 63. Une deuxième travée est illuminée par les dispositifs d'éclairage 121, 122, 123, 124 et 125. Ils sont alimentés par l'intermédiaire d'un câble d'alimentation 63'. Il est à noter que comme la tension de telles rampes peut rester à une valeur faible, ces lampes ne présentent pas de danger lors de chocs avec les véhicules en manœuvre. An area of application of such a ramp is the parking light This is shown in Figure 7. The parking is composed of two spans: a first span for vehicles VI, V2, ..., V5 and a second span for the vehicles Vi l, VI 2, ..., V15. Each of these bays is assigned a ramp. A first ramp is assigned to the first span and consists of the lighting devices 111, 112, 113, 114 and 115. These devices are powered by the cable 63. A second bay is illuminated by the lighting devices 121, 122 , 123, 124 and 125. They are powered via a power cable 63 '. It should be noted that since the voltage of such ramps can remain at a low value, these lamps do not present any danger during shocks with the vehicles in operation.
Un autre exemple d'application de l'invention est montré à à la figure 8. Dans cet exemple la lampe est fixée au plafond d'un local et on a inséré une caméra vidéo 210 pour la surveillance de ce local. L'objectif de cette caméra affleure le niveau extérieur de la facette F5, comme cela est représenté à la figure 9. Sa disposition est telle qu'elle permet de voir des objets selon un angle a le plus important possible et elle est suffisamment enfoncée pour éviter l'éblouissement apporté par les diodes LED environnantes. Another example of application of the invention is shown in FIG. 8. In this example the lamp is fixed to the ceiling of a room and a video camera 210 has been inserted for the surveillance of this room. The objective of this camera is flush with the outer level of the F5 facet, as shown in Figure 9. Its layout is such that it allows objects to be viewed at an angle as large as possible and is sufficiently depressed to avoid the glare provided by the surrounding LEDs.
Cette caméra 215 est connectée à un dispositif CPL 217 (dispositif de couplage par courant porteur en ligne) qui permet de transmettre sur une même ligne un courant d'alimentation et des données, donc les images captées par la caméra 215, vers un pôle de surveillance 300 pour être visualisées sur un écran 310. Les images sont accessibles au niveau du pôle de surveillance 300 par un autre dispositif CPL 317 en transitant par le câble 63. La référence 330 indique une source d'alimentation pour au moins une lampe. On peut prévoir, au niveau du pôle de surveillance 300, différents dispositifs CPL 320, 321,.. affectés à différentes caméras faisant partie de différentes lampes. This camera 215 is connected to a PLC device 217 (in-line carrier current coupling device) which makes it possible to transmit on the same line a supply current and data, therefore the images picked up by the camera 215, to a pole of 300 to be viewed on a screen 310. The images are accessible at the monitoring pole 300 by another PLC device 317 through the cable 63. The reference 330 indicates a power source for at least one lamp. It is possible to provide, at the monitoring pole 300, various CPL devices 320, 321, .. assigned to different cameras belonging to different lamps.
La figure 10 montre que, tout comme sur la figure 5, les différents éléments y compris le dispositif de couplage 217 sont placés sous les facettes d'illumination Fl ...F5.. Figure 10 shows that, as in Figure 5, the various elements including the coupling device 217 are placed under the illumination facets Fl ... F5 ..
Le dispositif d'éclairage trouve une autre application dans le cadre de l'éclairage d'un local tel que bureau ou salle de réunion. Il est possible dans l'embase 5 de la lampe de fixer un relais WIFI fort utilisé dans ce genre de pièce. Ceci est montré par la référence 350. Ceci permet aux participants réunis dans la salle de travail d'avoir une connexion aisée au réseau WIFI. The lighting device finds another application in the context of lighting a room such as office or meeting room.
