Abstract

The device has a photo voltaic cell (9), and a mirror (1) actuated by two motors (2) whose functions are controlled by vertical and horizontal sensors (4, 5). Each sensor has an optical system made of photo electric cells lit by a Plexiglas (RTM) bar trimmed on back of a prism sequence protected from interfering rays by a narrow case. The photo electric cells receiving solar rays position the mirror according to the rays.

Description

La présente invention concerne un dispositif pour éclairer une zone seThe present invention relates to a device for illuminating an area

trouvant à l'ombre à l'aide de la lumière solaire.  finding shade using sunlight.

Actuellement, on peut réfléchir les rayons solaires en utilisant un miroir afin d'éclairer un point sombre, par exemple, une pièce d'habitation située au nord, mais cet éclairage est fugitif.  Currently, we can reflect the sun's rays using a mirror to illuminate a dark spot, for example, a room in the north, but this lighting is fleeting.

Le dispositif permet de maintenir des rayons solaires réfléchis en un point plus ou moins fixe, malgré les divers déplacements du soleil au long de la journée et de l'année.  The device makes it possible to maintain solar rays reflected at a more or less fixed point, despite the various movements of the sun throughout the day and throughout the year.

Il se peut que l'on ait déjà obtenu ce résultat mais en mettant en oeuvre des 10 moyens d'une importance incompatible avec un petit appareil destiné au grand public. L'intérêt du présent procédé est d'utiliser des solutions simples et peu coûteuses.  It may be that this result has already been obtained, but by implementing means of an importance incompatible with a small device intended for the general public. The advantage of the present process is to use simple and inexpensive solutions.

Il comporte, selon une première caractéristique un miroir (1) actionné par deux moteurs électriques (2) lui permettant de se déplacer en site et en azimuts 15 tout en gardant un côté fixe par rapport aux axes.  According to a first characteristic, it comprises a mirror (1) actuated by two electric motors (2) allowing it to move in elevation and in azimuths 15 while keeping a fixed side with respect to the axes.

Un premier capteur vertical (4), monté sur la partie fixe du dispositif, comporte un système optique constitué d'une ou plusieurs cellules photoélectriques (12) éclairées par une barre de plexiglas taillée sur sa partie arrière d'une succession de prismes (13) permettant de diriger les rayons vers la 20 ou les cellules et protégé par un boîtier assurant la directivité est monté sur la partie fixe du dispositif (6). Ce capteur comporte une possibilité de réglage (8) qui permet d'assurer le repérage en site du point à éclairer.  A first vertical sensor (4), mounted on the fixed part of the device, comprises an optical system consisting of one or more photoelectric cells (12) illuminated by a plexiglass bar cut on its rear part from a succession of prisms (13 ) allowing the rays to be directed towards the cell (s) and protected by a box ensuring directivity is mounted on the fixed part of the device (6). This sensor has an adjustment possibility (8) which makes it possible to locate the point to be illuminated on site.

Un deuxième capteur horizontal (5) constitué, selon le principe du précédent, comportant deux systèmes optiques superposés est monté sur la base 25 tournante du dispositif Il comporte, lui aussi, une possibilité de réglage (7) qui permet d'assurer le repérage en azimut du point à éclairer.  A second horizontal sensor (5) constituted, according to the principle of the previous one, comprising two superimposed optical systems is mounted on the rotating base of the device. It also includes an adjustment possibility (7) which makes it possible to locate in azimuth of the point to be lit.

Une cellule photoélectrique (3) permet de s'assurer de la présence du soleil et commande le démarrage ou l'arrêt de l'ensemble.  A photoelectric cell (3) ensures the presence of the sun and controls the starting or stopping of the assembly.

Ces différents capteurs, en fonction des rayons reçus, transmettent à un circuit électronique simple, enfermé dans un boîtier étanche (10) les indications pour alimenter les moteurs de telle façon que le miroir, tout en suivant la course du soleil, maintienne le rayon vers le point défini.  These various sensors, depending on the rays received, transmit to a simple electronic circuit, enclosed in a sealed box (10), the indications for supplying the motors in such a way that the mirror, while following the path of the sun, maintains the ray towards the defined point.

Mécaniquement, l'axe de site est constitué d'un roulement à billes (1i1) assez important pour permettre une bonne stabilité du miroir malgré le porte à faux. Il est entraîné par l'intermédiaire d'un engrenage à vis sans fin pour garantir le maintient de la position malgré les sollicitations extérieures (vent) sans endommager la partie réducteur de vitesse du moteur.  Mechanically, the elevation axis consists of a ball bearing (1i1) large enough to allow good stability of the mirror despite the overhang. It is driven by a worm gear to guarantee the maintenance of the position despite the external stresses (wind) without damaging the speed reducing part of the motor.

Le miroir est fixé à sa base par une charnière lui permettant de s'incliner.  The mirror is fixed to its base by a hinge allowing it to tilt.

Le déplacement en azimut se fait à l'arrière du miroir par un engrenage à crémaillère lui même précédé d'un renvoi intermédiaire par vis sans fin pour la raison précédemment exposée.  The displacement in azimuth is made at the rear of the mirror by a rack and pinion gear itself preceded by an intermediate deflection by worm for the reason previously explained.

Le roulement à billes servant de pivot central, comporte deux butées (non représentées sur la figure) déterminant des fins de courses droite et gauche qui, actionnant des micro-rupteurs permettent, par l'intermédiaire d'un relais.  The ball bearing serving as central pivot, has two stops (not shown in the figure) determining right and left limit switches which, actuating micro-switches allow, via a relay.

d'inverser le sens de rotation du moteur de site quant le miroir arrive en bout de course et de le repositionner sur son point de départ à l'est. Le balayage reprend 15 alors de gauche à droite jusqu'à ce que le rayon réfléchi rencontre le capteur (4) et arrête le moteur. Dans cette position, un relais permet au moteur d'azimut de se déclencher en fonction des informations fournies par le capteur horizontal. En effet, celui-ci alimentera le moteur dans un sens ou dans un autre selon l'éclairage de ces deux cellules: Les deux cellules éteintes = basculement avant La cellule du haut éclairée, la cellule du bas éteinte = arrêt Les deux cellules éclairées= basculement arrière Si la situation du dispositif ne permet pas de le raccorder au réseau électrique, il peut être équipé de cellule photovoltaïque qui le rendront totalement 25 autonome.  to reverse the direction of rotation of the site engine when the mirror reaches the end of its travel and to reposition it on its starting point to the east. The scanning then resumes from left to right until the reflected ray meets the sensor (4) and stops the engine. In this position, a relay allows the azimuth motor to trip based on the information provided by the horizontal sensor. Indeed, it will power the motor in one direction or another depending on the lighting of these two cells: The two cells off = tilting before The top cell illuminated, the bottom cell off = off The two illuminated cells = rear tilting If the situation of the device does not allow it to be connected to the electrical network, it can be equipped with photovoltaic cell which will make it completely autonomous.

L'ensemble du dispositif sera fixé en un lieu recevant le maximum de soleil possible et se situant face au point à éclairer (immeuble voisin, poteau existant ou installé à dessein).  The entire system will be fixed in a location receiving the maximum possible amount of sun and located opposite the point to be lit (neighboring building, existing or intentionally installed pole).

Le dispositif, selon l'invention, est destiné à l'amélioration de l'éclairage 30 de l'habitat, la mise en valeur d'un point extérieur mais situé à l'ombre (statue, plaque commémorative...) ou la production d'effets spéciaux pour le commerce ou la publicité de façon directe ou à l'aide de système de diffusion ou de réflexion par exemple une boule à facettes.  The device according to the invention is intended for improving the lighting 30 of the habitat, the enhancement of an external point but located in the shade (statue, commemorative plaque ...) or the production of special effects for trade or advertising directly or using a diffusion or reflection system, for example a mirror ball.
