Abstract

The projector is characterized in that it includes two coaxial circular cylinders (7) and (8), which can turn and translate relative to each other in order to align a particular combination of a coloured filter (14;) and a shaping diaphragm (13;) between a source (4) and an objective (lens) (2). 1 it is usable in coloured lighting effects (chromatic animation).

Description

La présente invention a pour objet un projecteur de faisceaux lumineux de couleurs et formes variées.The present invention relates to a light beam projector of various colors and shapes.

Elle est donc relative au domaine technique des projecteurs lumineux colorés à effets variables.It therefore relates to the technical field of colored light projectors with variable effects.

Des projecteurs de ce genre déjà connus existent en de nombreux modes divers de réalisation. Ils ont en commun de comporter une source de lumière blanche émettant un flux qui traverse un filtre coloré et éventuellement un diaphragme de mise en forme du flux en section et ces filtres et diaphragmes sont montés sur des tourelles coaxiales rotatives de sorte que l'on peut aligner coaxialement avec le flux un filtre et un diaphragme choisis parmi les n filtres et les p diaphragmes donnant ainsi n.p combinaisons possibles de couleur et forme.Projectors of this kind already known exist in many different embodiments. They have in common to include a white light source emitting a flux which crosses a colored filter and possibly a diaphragm for shaping the flux in section and these filters and diaphragms are mounted on rotating coaxial turrets so that one can align coaxially with the flow a filter and a diaphragm chosen from among the n filters and p diaphragms thus giving np possible combinations of color and shape.

De tels projecteurs sont couramment utilisés dans des procédés d'animation chromatique en vue d'obtenir des effets d'ambiance tels qu'on peut en désirer dans des théatres, des studios, ou des lieux publics divers.Such projectors are commonly used in chromatic animation processes in order to obtain ambient effects such as may be desired in theaters, studios, or various public places.

Ces projecteurs sont volumineux et encombrants et ne permettent pas d'obtenir un grand nombre possible de combinaisons distinctes de couleurs et de formes pour le flux.These projectors are bulky and bulky and do not make it possible to obtain a large number of distinct combinations of colors and shapes for the stream.

En outre, les moyens accessoires pour la mise en mouvement de tels projecteurs dans l'espace, généralement nécessaires pour ltobtention d'une animation chromatique satisfaisante, sont en conséquence également volumineux et encombrants.In addition, the accessory means for setting in motion such projectors in space, generally necessary for obtaining satisfactory chromatic animation, are consequently also bulky and bulky.

La présente invention a pour but d'éliminer ces deux inconvé nients en imaginant une nouvelle architecture de projecteur permettant, à la fois: d'une part, d'obtenir un très grand nombre possible de faisceaux lumineux colorés se distinguant tous les uns des autres par une combinaison différente d'une couleur parmi N ,(N n), couleurs et d'une forme parmi P,(P p), formes et, d'autre part, de réaliser un projecteur compact susceptible d'être animé de manière simple de mouvements tridimen-sionnels dans l'espace. The object of the present invention is to eliminate these two drawbacks by imagining a new projector architecture making it possible, at the same time: on the one hand, to obtain a very large number of colored light beams which can be distinguished from each other. by a different combination of a color among N, (N n), colors and a form among P, (P p), forms and, on the other hand, to produce a compact projector capable of being animated so simple three-dimensional movement in space.

A ces effets, l'invention a pour objet un projecteur de faisceaux lumineux de couleurs et formes variées, du genre comportant une source de lumière blanche émettant un flux traversant un filtre coloré et un diaphragme de mise en forme, caractérisé en ce que les filtres- colorés et les diaphragmes de mise en forme sont portés respectivement par deux cylindres circulaires co axiaux et que des moyens sont prévus pour permettre des mouve ments relatifs de rotation et de translation de ces deux cylindres l'un par rapport à l'autre.For these effects, the subject of the invention is a projector of light beams of various colors and shapes, of the type comprising a white light source emitting a flux passing through a color filter and a shaping diaphragm, characterized in that the filters - colored and the shaping diaphragms are carried respectively by two circular co-axial cylinders and that means are provided to allow relative movements of rotation and translation of these two cylinders relative to each other.

On comprend aisément que ce choix d'architecture permet de regrouper les filtres colorés et les diaphragmes de manière compacte, puisque l'ensemble de ces deux cylindres a pour diamètre le plus grand des diamètres et pour longueur maxïmale la somme des longueurs des deux cylindres et qu'il permet d'organiser chaque cylindre en une matrice cylindrique de supports des fil-tres ou diaphragmes, dont on peut prévoir un grand nombre sous un faible encombrement, le nombre total de combinaisons possibles de filtres et diaphragmes étant égal à NxP .It is easy to understand that this choice of architecture makes it possible to group the colored filters and the diaphragms in a compact manner, since the assembly of these two cylinders has the largest diameter for diameter and for maximum length the sum of the lengths of the two cylinders and that it makes it possible to organize each cylinder into a cylindrical matrix of supports for the filters or diaphragms, a large number of which can be provided in a small footprint, the total number of possible combinations of filters and diaphragms being equal to NxP.

L'invention sera bien comprise à l'aide-de la description suivante d'un mode de réalisation faite en référence à la figure unique qui represente schématiquement en coupe longitudinale les différents composants fonctionnels d'un projecteur selon l'invention.The invention will be better understood with the aid of the following description of an embodiment made with reference to the single figure which schematically represents in longitudinal section the various functional components of a headlight according to the invention.

L'ensemble du projecteur est contenu dans un boitier cylindrique (1), qualifié ici de fixe, mais dont on imagine qu'il peut être mobile dans l'espace lorsque lton s'organise pour que l'ensemble du projecteur soit lui-même mobile dans l'espace. Le flux lumineux du projecteur sort par un objectif (2). The whole of the projector is contained in a cylindrical case (1), qualified here as fixed, but which one imagines that it can be mobile in space when lton is organized so that the whole of the projector is itself mobile in space. The luminous flux of the projector comes out through a lens (2).

Un élément fixe (3) est monté coaxialement au boitier cylindrique (1).A fixed element (3) is mounted coaxially with the cylindrical housing (1).

Cet élément supporte en sa partie médiane une source lumineuse fixe (4). Ses deux branches (5) et (6), de part et d'autre de la source (4), servent de support et de guide à deux cylindres circulaires coaxiaux (7) et (8) mobiles tous deux en rotation et translation par rapport à l'élément fixe (3) porteur de la source (4). Des moteurs, de préférence du type pas à pas, (9), (10), (11) et (12) commandent ces mouyements. This element supports in its middle part a fixed light source (4). Its two arms (5) and (6), on either side of the source (4), serve as support and guide for two coaxial circular cylinders (7) and (8) both movable in rotation and translation by relative to the fixed element (3) carrying the source (4). Motors, preferably of the stepping type, (9), (10), (11) and (12) control these movements.

Le cylindre t7) constitue une matrice cylindrique circulaire aux noeuds de laquelle sont situées autant de découpes de formes (13) différentes que le nombre P désiré Ces découpes-sont partiellement et schématiquement représentées sur la figure.The cylinder t7) constitutes a circular cylindrical matrix at the nodes of which are located as many cutouts of different shapes (13) as the desired number P These cutouts are partially and schematically shown in the figure.

Le cylindre (8) constitue une matrlce -cylindrique circulaire aux noeuds de laquelle sont situés autant de filtres colorés' -(-14) différents que le nombre N désiré,
Ces filtres sont partiellement et schématiquement représentés sur la figure.
The cylinder (8) constitutes a circular cylindrical matrix at the nodes of which are located as many different colored filters' - (- 14) as the number N desired,
These filters are partially and schematically shown in the figure.

On comprend aisément que, en commandant de façon appropriée les moteurs (9) à (12), on peut, en faisant tourner et se déplacer relativement les cylindres (7) et (8), aligner avec la source (4) et l'objectif (2) une combinaison particulière choisie (13i) - (14j) d'une forme et d'une couleur parmi les N.P com-binai sons possibles.It is easily understood that, by appropriately controlling the motors (9) to (12), it is possible, by rotating and relatively moving the cylinders (7) and (8), to align with the source (4) and the objective (2) a particular combination chosen (13i) - (14j) of a shape and a color from the NP com-binai sounds possible.

L'invention décrite ci-dessus l'a été dans ses principes fonctionnels. Il est évident que bien des variantes de réalisation peuvent être envisagées sans sortir du cadre de l'invention. The invention described above was in its functional principles. It is obvious that many variant embodiments can be envisaged without departing from the scope of the invention.
