Date Oct. 28, 1993A fluid optical system for focusing all entering light whatever its direction and incidence, and having an entrance surface through which the light enters. The optical system has a volume having an optical shape generated by a logarithmic spiral so that the focusing occurs for light beams entering the entrance surface from any direction through any point of the entrance surface. There flows in the optical shape a fluid which is maintained in forced circulation to form a fluid optical system, and which is forced to enter the optical system tangentially to the optical shape and adjacent to the entrance surface which is arranged so that initial circulation is tangential and laminar. Inside the optical system, the fluid has a centripetal rotation movement until it exits through a cone end of the optical shape, thus draining off calories.

Description

PROJBCTEOR A OPTIQUE FI-PTDE FI-PTDE OPTICAL PROJBCTEOR
La présente invention concerne l'optique industrielle de grande puissance. Il s'agit de créer un projecteur de lumière dont la puissance lumineuse peut être très supérieure à tout ce qui existe actuellement. L'utilisation d'un tel système ne nécessite pas de verre anticalorique pour projeter des images fixes ou mobiles d'où un gain considérable de rendement optique. Les projecteurs actuels sont traditionnellement composés d'une source lumineuse, d'un réflecteur et d'une lentille de sortie du type de la lentille de Fresnel. Leur puissance est limitée à 20 Kw. Cette puissance est limitée et nécessite l'utilisation de verre anticalorique pénalisant le rendement lumineux nécessaire aux projections d'images fixes. Le dispositif selon l'invention permet de remédier à cet inconvénient. La nature de l'invention consiste à utiliser les propriétés optiques et thermiques d'éléments fluides en état stable, ou mis en mouvement par convection naturelle, ou entretenu en mouvement forcé dans un récipient étudié aux formes intérieures optiques appropriées. On utilisera la variation forcée et entretenue de l'indice de réfraction par la maîtrise du gradient thermique du milieu fluide créant ainsi un gradient d'indice de réfraction. On utilise de plus les propriétés de transmission ou d'absorption d'une partie du flux lumineux par le fluide en fonction de la longueur d'onde. Il s'agit d'une optique qui recueille toute la lumière produite par une ou plusieurs sources lumineuses, quelque soit l'incidence du rayonnement d'entrée et sa position par rapport à sa face d'entrée, la canalise et la concentre en une nappe divergente dont la forme est figée. Cette optique utilise les propriétés de réfraction et réflexion totale,d'une part sur ses surfaces et dioptres selon les lois de Descartes-Snell et d'autre part au sein même du fluide en mouvement. On note que cette optique est contrôlée thermiquement par des mouvements forcés de fluides gazeux ou liquides. Ce nouveau système évite l'utilisation des filtres anticaloriques pénalisant les projecteurs actuels (rendement de 25 à 30 %) pour la projection des images fixes. Les filtres anticaloriques absorbent en effet une quantité non négligeable de lumière visible. La solution adoptée consiste à faire circuler un fluide transparent à la lumière visible et opaque aux autres rayons lumineux dans un récipient de forme appropriée et parfaitement définie de telle sorte que les lois de Descartes-Snell soient vérifiées et assujetties à une circulation laminaire créant en son sein un gradient thermique régulé favorisant la concentration de rayons lumineux par réflexions et réfractions successives.The present invention relates to high power industrial optics. It is a question of creating a light projector whose light power can be much higher than all that currently exists. The use of such a system does not require any heat-resistant glass to project fixed or moving images, hence a considerable gain in optical efficiency. Current projectors are traditionally composed of a light source, a reflector and an output lens of the Fresnel lens type. Their power is limited to 20 Kw. This power is limited and requires the use of heat-resistant glass which penalizes the light output necessary for projecting still images. The device according to the invention overcomes this drawback. The nature of the invention consists in using the optical and thermal properties of fluid elements in a stable state, or set in motion by natural convection, or maintained in forced movement in a container studied with appropriate optical interior shapes. We will use the forced and maintained variation of the refractive index by controlling the thermal gradient of the fluid medium thus creating a gradient of refractive index. In addition, the properties of transmission or absorption of part of the light flux by the fluid as a function of the wavelength are used. It is an optic which collects all the light produced by one or more light sources, whatever the incidence of the input radiation and its position relative to its entry face, channels and concentrates it into a divergent sheet whose shape is fixed. This optic uses the properties of refraction and total reflection, on the one hand on its surfaces and diopters according to the laws of Descartes-Snell and on the other hand within the moving fluid itself. It should be noted that this optic is thermally controlled by forced movements of gaseous or liquid fluids. This new system avoids the use of heat filters penalizing current projectors (efficiency of 25 to 30%) for the projection of still images. Heat filters absorb a significant amount of visible light.

Pour atteindre simultanément ce résultat il faut que la forme du volume de l'optique de concentration soit générée par la révolution d'un segment d'arc de spirale logarithmique. D'autres segments d'arcs, courbes ou approximations par_1ignés brisées seront aussi possibles pour générer cette forme de volume mais SEUL l'arc de spirale logarithmique donne le rendement optique maximum. D'autres formes que des formes de révolution sont également possibles. La figure n*l représente une perspective écorchée de l'optique fluide. La figure n°2 représente une coupe de l'optique fluide.To achieve this result simultaneously, the shape of the volume of the concentration optic must be generated by the revolution of a segment of arc of logarithmic spiral. Other arc segments, curves or approximations by broken lines will also be possible to generate this form of volume but ONLY the logarithmic spiral arc gives the maximum optical efficiency. Other forms than forms of revolution are also possible. Figure n * l shows a cutaway perspective of the fluid optics. Figure 2 shows a section of the fluid optics.
En référence aux figures n*l et nβ2, le dispositif comporte les éléments suivants numérotés.With reference to Figures n * l and n β 2, the device includes the following numbered elements.
La forme intérieure (1) constitue l'essentiel de l'OPTIQUE FLUIDE. Cette forme est générée par la révolution d'un arc de spirale logarithmique .The interior shape (1) constitutes the essential of the FLUID OPTICS. This shape is generated by the revolution of a logarithmic spiral arc.
La surface est recouverte d'un dépôt réfléchissant chromé, nickelé, argenté, ou constituée d'un dépôt de verre ou de tout autre système parfaitement réfléchissant. Cette forme peut être exécutée en fonderie sous pression ( fonderie d'aluminium, fonte ou tout autre matière ayant une bonne résistance mécanique et thermique) sur laquelle il est possible de fixer un dépôt réfléchissant. La géométrie intérieure doit être -.parfaite. Les récipients (2) et (3) supports de la forme intérieure,sont formés de deux enveloppes rendues solidaires par des vis et un joint ( ). Ces enveloppes peuvent extérieurement servir de radiateur pour évacuer les calories excédentaires par circulation forcée d'un fluide réfrigéré. L'enveloppe (5) extérieure retenant le fluide réfrigérant. Le Joint d'étanchéité (6). Le hublot (7) transparent formant la face d'entrée .L'étanchéité est réalisée par un joint torique. Le tout est maintenu par une bride de maintien (8) vissée. Le cône de sortie (9) de la forme intérieure du récipient marqué (1) est constitué de matière transparente tel un verre de qualité optique résistant très bien à la température. Ce cône est maintenu à l'ensemble (1),(2) et (3) par une bride de maintien (11).L'ensemble est rendu étanche par un joint torique (10).Le sommet (12) du cône est coiffé d'une collerette d'écoulement qui permet l'évacuation du fluide optique A pour sa remise en froid.The surface is covered with a chrome, nickel-plated, silver reflective deposit, or made up of a deposit of glass or any other perfectly reflecting system. This form can be performed in a pressure foundry (aluminum foundry, cast iron or any other material having good mechanical and thermal resistance) on which it is possible to fix a reflective deposit. The interior geometry must be - perfect. The receptacles (2) and (3) supports of the internal shape, are formed of two envelopes made integral by screws and a seal (). These envelopes can externally serve as a radiator to evacuate excess calories by forced circulation of a refrigerated fluid. The outer casing (5) retaining the refrigerant. The seal (6). The transparent porthole (7) forming the inlet face. The seal is produced by an O-ring. The whole is held in place by a screwed retaining strap (8). The outlet cone (9) of the interior shape of the marked container (1) is made of transparent material such as glass of optical quality very resistant to temperature. This cone is held to the assembly (1), (2) and (3) by a retaining flange (11). The assembly is sealed by an O-ring (10). The top (12) of the cone is wearing a flow collar which allows the evacuation of the optical fluid A for its cooling.
Pour le bon fonctionnement de l'ensemble, il est impératif de créer une circulation forcée du fluide optique A qui doit être assujetti à pénétrer dans l'optique de façon tangentielle à la forme optique et le plus près possible de la face d'entrée disposée de telle sorte que la circulation initiale soit tangentielle et laminaire. Le fluide doit dans toute l'optique être animé d'un mouvement de rotation centripète jusqu'à son évacuation par le sommet du cône de sortie. La collerette (13) d'écoulement contribue à évacuer le fluide optique A vers un dispositif de refroidissement et de filtrage en circuit fermé (15) grâce à une tuyauterie (14). C'est en effet ce fluide qui évacue en partie l'énergie calorifique inutile créée par le rayonnement infra-rouge. La tuyauterie (14) d'évacuation sera aplatie dans le sens du flux lumineux pour occulter au minimum le faisceau de sortie.For the proper functioning of the assembly, it is imperative to create a forced circulation of the optical fluid A which must be subjected to penetrate the optics tangentially to the optical form and as close as possible to the inlet face disposed so that the initial circulation is tangential and laminar. The fluid must in all optics be animated by a centripetal movement of rotation until its evacuation by the top of the outlet cone. The flow flange (13) contributes to evacuating the optical fluid A towards a cooling and filtering device in closed circuit (15) by means of a pipe (14). It is indeed this fluid which partially removes the unnecessary heat energy created by infrared radiation. The discharge pipe (14) will be flattened in the direction of the light flow to at least obscure the outlet beam.
Dispositif (15) en circuit fermé comportant un filtre, une pompe et un échangeur thermique. Le fluide thermique B de refroidissement (16) du radiateur périphérique pénètre du côté de la face d'entrée optique (face la plus chaude). La sortie se fera du côté du cône de sortie. Tout l'ensemble devra être mis en oeuvre et contrôlé par un servomécanisme. L'ensemble devra être piloté à partir de points de test de température, de pression et de débit répartis sur les endroits stratégiques du circuit fluide de refroidissement. La création d'un projecteur à optique de TRES GRANDE PUISSANCE permet d'augmenter de façon non négligeable le -rendement optique et de diversifier le domaine d'application de ces appareils. Ce type de projecteur est capable de reproduire une image fixe ou mobile sur un écran (nuages ou édifices publics) situés à grande distance. Le projecteur convient donc bien pour les spectacles de sons et lumières ou les représentations extérieures de grande envergure. Il permet aussi la projection de nappes de grande intensité lumineuse, de grande ouverture de faisceau ( environ 170*) à grande distance.Closed circuit device (15) comprising a filter, a pump and a heat exchanger. The thermal fluid B for cooling (16) of the peripheral radiator penetrates on the side of the optical inlet face (hottest face). The exit will be on the side of the exit cone. The whole assembly must be implemented and controlled by a servomechanism. The assembly must be controlled from temperature, pressure and flow test points distributed over strategic locations in the coolant circuit. The creation of a VERY LARGE POWER optic projector makes it possible to significantly increase the optical efficiency and to diversify the field of application of these devices. This type of projector is capable of reproducing a fixed or moving image on a screen (clouds or public buildings) located at great distance. The projector is therefore well suited for light and sound shows or large-scale outdoor performances. It also allows the projection of tablecloths of great light intensity, of large beam opening (about 170 * ) at long distance.
Son utilisation peut convenir aussi dans l'éclairage de grands chantiers de travaux publics (tels les constructions de barrages ou ouvrages d'art) les grandes installations portuaires comme Antifer, apportant de ce fait une sécurité visuelle supplémentaire au personnel. D'autres applications comme la mise en valeur de sites prestigieux peuvent également être envisagées. II est aussi possible en changeant de fluide et en le choisissant pour ses propriétés de transmission ou d'absorption d'une partie du flux lumineux en fonction de sa longueur d'onde, d'utiliser ce projecteur par visibilité réduite due à la présence de brumes et brouillards, (éclairage de ports, de pistes d'atterrissage ou de noeuds routiers). Il est encore possible en utilisant des produits pâteux ou solides,présentant évidemment les mêmes propriétés optiques, d'embarquer ces projecteurs sur des mobiles roulants, volants ou flottants. Il est aussi possible d'utiliser un volume vide de tout fluide en mettant à profit la seule propriété optique créée par la spirale de révolution.Its use can also be suitable for lighting large public works sites (such as the construction of dams or engineering structures), large port facilities such as Antifer, thereby providing additional visual security for staff. Other applications such as the enhancement of prestigious sites can also be considered. It is also possible by changing the fluid and choosing it for its transmission or absorption properties of part of the light flux as a function of its wavelength, to use this projector in reduced visibility due to the presence of mists and mists, (lighting of harbors, airstrips or road nodes). It is still possible by using pasty or solid products, obviously having the same optical properties, to embed these projectors on rolling, flying or floating mobiles. It is also possible to use a volume empty of any fluid by taking advantage of the only optical property created by the spiral of revolution.
Dans tous ces cas ,on rappelle qu'il est impératif de toujours respecter la forme intérieure du volume de l'optique de concentration, qu'elle soit de révolution ou non. II est enfin possible de créer un bloc monolithique solide et transparent comme le verre ou le plastique.In all these cases, it is recalled that it is imperative to always respect the internal shape of the volume of the concentration optic, whether it is of revolution or not. It is finally possible to create a solid monolithic block and transparent like glass or plastic.
Ce bloc, dont la forme extérieure (dioptre utile) doit respecter celle du volume de l'optique fluide pourrait aussi concentrer les rayons lumineux de la même manière. On note enfin que le fonctionnement de tels projecteurs ne produit pas de dégagement thermique dans l'environnement ni dans le flux lumineux. This block, whose external shape (useful diopter) must respect that of the volume of the fluid optics could also concentrate the light rays in the same way. Finally, it should be noted that the operation of such projectors does not produce thermal release in the environment or in the light flux.
