DESCRIPTIONDESCRIPTION
La presente invention concerne le domaine de l'eclairage par projecteur. Plus particulierement, elle concerne le domaine de l'eclairage par projecteur a faisceau reglable (<< projecteur a decoupe zoom >>). Wile a pour objet un nez amovible pour projecteur pouvant etre monte sur un projecteur simple afin d'en faire un projecteur a faisceau reglable. Un tel accessoire, designe dans ce qui suit par << nez de projecteur >> ou << nez de decoupe >>, permet de transformer un projecteur standard a The present invention relates to the field of projector lighting. More particularly, it relates to the field of lighting by adjustable beam projector (“zoom cut projector”). Wile's object is a removable projector nose that can be mounted on a single projector to make it an adjustable beam projector. Such an accessory, designated in the following by "projector nose" or "cutting nose", makes it possible to transform a standard projector to
optique fixe en projecteur a decoupe zoom. fixed optic in zoom cut projector.
Dans le domaine de l'eclairage par projecteur, englobant les domaines de l'eclairage interieur et de lteclairage exterieur, il existe un grand nombre de differents types de projecteurs avec differentes optiques ou systemes optiques faisant partie integrante de l'appareil d'eclairage. La plupart de ces projecteurs vent des projecteurs simples essentiellement constitues d'une source lumineuse et d'un reflecteur. D'autres projecteurs ont notamment comme caracteristique de projeter un faisceau reglable. Par faisceau reglable, on entend un faisceau dont un certain nombre de caracteristiques, notamment des caracteristiques de forme de faisceau, vent reglables. Il s'agit notamment d'un faisceau ou cone lumineux bien defini avec une geometric, un angle de conicite et un point focal que lton peut regler. Il peut s'agir egalement d'un faisceau dont la couleur peut etre reglee. Il peut s'agir enfin d'un faisceau mis en forme de maniere a projeter une image simple. Le terme faisceau reglable tel qu'utilise ici n'englobe pas les faisceaux a reglage simple que projettent les projecteurs simples de type classique. Un projecteur simple de type classique comporte generalement un chassis permettant de fixer de maniere amovible sur le projecteur un accessoire simple. Il peut s'agir, par exemple, d'un refracteur, d'une grille de defilement, d'une grille de protection, de volets de cadrage, de verrerie - 2 - sablee, d'un porte-filtre de couleur ou d'une visiere. L'installation d'un tel accessoire ne permet qu'un type de reglage du faisceau a la fois, par exemple le reglage de la couleur. I1 ne permet pas de reglage fin de la forme du faisceau. Le refracteur ou le chassis a volets permettent un certain reglage de la forme du faisceau, mais sans grande precision. Un projecteur a faisceau reglable comprend generalement une source lumineuse, un reflecteur et un systeme de lentilles a focale variable du type zoom. I1 peut comprendre egalement des accessoires permettant le reglage de la couleur et la mise en forme du faisceau comme des porte filtres de couleur, des refracteurs, des grilles de defilement, des verres sables, des volets coupe flux, des ensembles a couteaux de decoupe, des In the field of projector lighting, encompassing the fields of interior lighting and exterior lighting, there are a large number of different types of projectors with different optics or optical systems forming an integral part of the lighting apparatus. Most of these projectors sell simple projectors essentially consisting of a light source and a reflector. Other projectors have in particular the characteristic of projecting an adjustable beam. By adjustable beam is meant a beam of which a certain number of characteristics, in particular beam shape characteristics, adjustable wind. These include a well defined light beam or cone with a geometric, a conicity angle and a focal point that can be adjusted. It can also be a beam whose color can be adjusted. Finally, it can be a beam shaped so as to project a simple image. The term adjustable beam as used here does not include beams with simple adjustment which are projected by simple spotlights of the conventional type. A simple projector of the conventional type generally comprises a frame making it possible to removably attach a simple accessory to the projector. It can be, for example, a refractor, a scrolling grid, a protective grid, framing shutters, glassware - 2 - sand, a color filter holder or a 'a visor. The installation of such an accessory only allows one type of beam adjustment at a time, for example color adjustment. I1 does not allow fine adjustment of the shape of the beam. The refractor or the shutter frame allow a certain adjustment of the shape of the beam, but without great precision. An adjustable beam projector generally includes a light source, a reflector and a zoom lens system of variable focal lengths. It can also include accessories allowing the adjustment of the color and the shaping of the beam such as color filter holders, refractors, scrolling grilles, sand glasses, flow shutters, sets of cutting knives, of the
diaphragmes, des porte-gobos et autres. diaphragms, gobo holders and the like.
Un tel projecteur a faisceau reglable peut permettre de projeter une image simple ou un motif. L'image peut etre obtenue en utilisant, isolement ou en combinaison, un diaphragme, des couteaux de decoupe et des gobos metalliques ou en verre. De tels projecteurs vent decrits, par exemple, dans Such an adjustable beam projector can be used to project a simple image or a pattern. The image can be obtained using, individually or in combination, a diaphragm, cutting knives and metallic or glass gobos. Such wind projectors described, for example, in
les publications EP 0 563 483, US 6 092 914 ou WO 01/84043. the publications EP 0 563 483, US 6 092 914 or WO 01/84043.
Les projecteurs a faisceau reglable existent presentent [ ' inconvenient d' etre peu souples a utiliser. Par exemple pour l' eclairage en exterieur, le projecteur doit etre isole de l'exterieur par un capotage devant respecter des normes extremement severes afin de proteger la source lumineuse. Un tel capotage peut etre realise sur les projecteurs a faisceau reglable existants mais il rend difficile ou couteux le reglage sur site du projecteur. Par exemple, il oblige a automatiser le deplacement des lentilles ou des couteaux de decoupe et rend pratiquement impossible la mise en Adjustable beam headlamps exist which have the disadvantage of being not very flexible to use. For example, for outdoor lighting, the projector must be isolated from the outside by a casing which must meet extremely strict standards in order to protect the light source. Such a cover can be achieved on existing adjustable beam projectors but it makes it difficult or expensive to adjust the projector on site. For example, it forces to automate the movement of lenses or cutting knives and makes it practically impossible to
aeuvre de porte-gobos amovibles.work of removable gobo holders.
Outre le fait que tout reglage pratique du dispositif de decoupe, de gobo ou du dispositif optique de zoom est quasiment impossible, un capotage complet et etanche du projecteur aboutit de surcro^t a des elevations de temperature incompatibles avec le bon fonctionnement et la In addition to the fact that any practical adjustment of the cutting device, gobo or optical zoom device is almost impossible, a complete and watertight covering of the projector also results in temperature rises incompatible with the proper functioning and
duree de vie des sources de lumiere. lifetime of light sources.
La presente invention a notamment pour objet de pallier les inconvenients des projecteurs a faisceau reglable existants et notamment de proposer un projecteur a faisceau reglable utilisable en exterieur pouvant The object of the present invention is in particular to alleviate the drawbacks of existing adjustable beam projectors and in particular to propose an adjustable beam projector usable outdoors
etre regle sur site facilement et a moindre cout. be paid on site easily and cheaply.
A cet effet, la presente invention a pour objet un projecteur a faisceau reglable, comprenant une source lumineuse, un reflecteur et des moyens de reglage du faisceau, caracterise en ce que, d'une part, un corps de projecteur renferme ladite source lumineuse et ledit reflecteur et, d'autre part, un nez de projecteur renferme lesdits moyens de reglage du faisceau, ledit nez de projecteur pouvant etre fixe de maniere amovible sur ledit corps de projecteur afin de recevoir un faisceau lumineux emis par ledit corps de projecteur, transmettre ledit faisceau a travers lesdits moyens de reglage pour modifer ledit faisceau et emettre ledit faisceau modifie, ledit corps de projecteur et ledit nez de projecteur etant hermetiquement isoles l'un de l'autre. Ainsi, le nez de projecteur, contenant les accessoires permettant le reglage du faisceau, est isole (electriquement) du corps de projecteur contenant la source lumineuse. Le nez de projecteur ne contenant aucun element electrique, son isolation n'a pas a repondre aux normes en vigueur pour un projecteur installe a l'exterieur. De ce fait, la mise en aeuvre d'accessoires comme des portegobos amovibles ou comme des couteaux To this end, the subject of the present invention is a headlamp with adjustable beam, comprising a light source, a reflector and means for adjusting the beam, characterized in that, on the one hand, a headlamp body contains said light source and said reflector and, on the other hand, a projector nose encloses said beam adjustment means, said projector nose can be removably fixed on said projector body in order to receive a light beam emitted by said projector body, transmit said beam through said adjustment means for modifying said beam and emitting said modified beam, said headlamp body and said headlamp nose being hermetically isolated from each other. Thus, the projector nose, containing the accessories enabling the beam to be adjusted, is (electrically) isolated from the projector body containing the light source. Since the projector nose does not contain any electrical elements, its insulation does not have to meet the standards in force for a projector installed outside. As a result, the implementation of accessories such as removable portegos or knives
de decoupe reglables manuellement ne pose pas de probleme. manually adjustable cutting no problem.
Selon un autre aspect de la presente invention, ledit nez de projecteur comprend un anneau de fixation adapte a etre fxe sur un chassis audit corps de projecteur, des moyens de fixation menages sur ledit anneau According to another aspect of the present invention, said projector nose comprises a fixing ring adapted to be fixed on a frame to said projector body, household fixing means on said ring
de fixation cooperant avec des moyens de fixation audit chassis. fixing cooperating with fixing means to said chassis.
Ainsi, le nez peut etre fxe sur n'importe quel type de projecteur existent et notamment un projecteur exterieur muni d'un capot d'isolation - 4 repondant aux normes en vigueur. En effet, un projecteur simple de type classique comporte generalement un chassis permettant de fixer de maniere amovible sur le projecteur un accessoire simple comme, par exemple, un refracteur. Dans le cas ou le corps de projecteur ne comporterait pas de tel chassis, l'on peut percer le chassis de la vitre du projecteur pour y installer des moyens de fixation adaptes a cooperer avec lesdits moyens de fixation audit anneau de fixation du nez de projecteur. De la sorte, l' on peut transformer un simple projecteur en projecteur a decoupe ou en projecteur a gobos. Avantageusement, lesdits moyens de fixation audit chassis vent des tiges adaptees a s'inserer dans des fentes s'etendant circulairement menagees dans ledit anneau de fixation, lesdites tiges etant pourvues de renflements de blocage de tailles superieures a la largeur desdites fentes circulaires, des trous adaptes a ['introduction desdites tiges etant menages Thus, the nose can be fixed on any type of projector available and in particular an exterior projector fitted with an insulation cover - 4 meeting the standards in force. Indeed, a simple projector of the conventional type generally comprises a frame making it possible to removably attach to the projector a simple accessory such as, for example, a refractor. In the case where the headlamp body does not include such a frame, it is possible to pierce the frame of the projector glass to install fixing means there adapted to cooperate with said fixing means to said fixing ring of the headlamp nose . In this way, you can transform a simple projector into a cutout projector or a gobo projector. Advantageously, said means for fixing to said wind frame rods adapted to be inserted into slots extending circularly formed in said fixing ring, said rods being provided with blocking bulges of sizes greater than the width of said circular slots, suitable for the introduction of said rods being household
en communication avec lesdites fentes circulaires. in communication with said circular slots.
De la sorte, apres introduction des tiges du chassis du corps dans les trous de l'anneau de fixation du nez, la fixation du nez sur le corps se fait par rotation du nez, les tiges coulissant dans les fentes, les renflements des tiges se trouvant du cote de l'anneau oppose au chassis et assurant done le blocage du nez sur le corps. Pour enlever le nez, il suffit de faire tourner ce dernier dans l'autre sens jusqu'a ce que les tiges se trouvent a nouveau dans les trous. I1 ne reste plus alors qu'a retirer le nez. Ce principe de fixation correspond globalement a ce que l'on appelle communement "fixation par In this way, after introducing the rods of the body chassis into the holes of the nose fixing ring, the fixing of the nose on the body is done by rotation of the nose, the rods sliding in the slots, the bulges of the rods finding the side of the ring opposite the chassis and thus ensuring the blocking of the nose on the body. To remove the nose, simply rotate the nose in the opposite direction until the rods are again in the holes. I1 only remains then to remove the nose. This fixing principle broadly corresponds to what is commonly called "fixing by
baonnette" (ergots engages dans des crans par rotation). bayonet "(pins engaged in notches by rotation).
Selon un autre aspect de la presente invention, ledit nez de projecteur comprend un dispositif a couteaux de decoupe pour le reglage de According to another aspect of the present invention, said projector nose comprises a device with cutting knives for adjusting
la forme du faisceau.the shape of the beam.
Avantageusement, ledit dispositif a couteaux de decoupe comprend une pluralite de plaques en forme d'anneau adaptees a coulisser le long de moyens de guidage s'etendant perpendiculairement auxdites plaques, un moyen de sollicitation etant menage pour solliciter lesdites plaques les unes contre les autres, au moins un couteau de decoupe etant insere entre chaque Advantageously, said device with cutting knives comprises a plurality of ring-shaped plates adapted to slide along guide means extending perpendicularly to said plates, a biasing means being arranged to urge said plates against one another, at least one cutting knife being inserted between each
paire de plaques.pair of plates.
Ainsi, l'on dispose d'un moyen de reglage de forme par couteaux de decoupe pouvant comporter un nombre quelconque de couteaux de decoupe, ces couteaux de decoupe pouvant etre positionnes dans n'importe quelle configuration puisque chaque couteau de decoupe peut evoluer dans un plan qui lui est propre. Chaque couteau de decoupe, de maniere classique, comporte une plaque, dont le bord de decoupe peut etre droit mais egalement avoir toute forme possible, et un manche permettant la manipulation du couteau depuis l'exterieur. Chaque couteau de decoupe peut glisser entre les plaques lorsqu'un effort est exerce sur son manche, mais il reste immobile lorsque l'effort est relache, les deux plaques entre lesquelles il evolue etant sollicitees l'une contre l'autre par ledit moyen de sollicitation. Ce moyen de sollicitation est regle pour exercer une charge permettant l'immobilisation des couteaux lorsque aucun effort n'est exerce sur leurs manches tout en permettant le deplacement de ces couteaux par un Thus, there is a means for adjusting the shape by cutting knives which may include any number of cutting knives, these cutting knives being able to be positioned in any configuration since each cutting knife can evolve in one its own plan. Each cutting knife, in a conventional manner, comprises a plate, the cutting edge of which can be straight but also have any possible shape, and a handle allowing the knife to be manipulated from the outside. Each cutting knife can slide between the plates when an effort is exerted on its handle, but it remains stationary when the effort is released, the two plates between which it moves being pressed against each other by said means of solicitation. This solicitation means is regulated to exert a load allowing the immobilization of the knives when no effort is exerted on their handles while allowing the displacement of these knives by a
operateur agissant sur ces manches.operator acting on these sleeves.
Avantageusement, ledit dispositif a couteaux de decoupe comprend egalement un moyen de verrouillage adapte a serrer lesdites plaques les unes contre les autres afin que lesdits couteaux ne puissent plus glisser entre Advantageously, said device for cutting knives also comprises a locking means adapted to clamp said plates against each other so that said knives can no longer slide between
lesdites plaques.said plates.
Ainsi, une fois le reglage termine, le dispositif a couteaux de Thus, once the adjustment is complete, the knife device
decoupe peut etre verrouille.cutout can be locked.
Selon une autre caracteristique avantageuse, ledit dispositif a couteaux de decoupe comprend trois plaques en forme d'anneau, deux couteaux de decoupe etant inseres entre une premiere et une seconde plaque et deux autres couteaux de decoupe etant inseres entre ladite seconde plaque According to another advantageous characteristic, said device with cutting knives comprises three ring-shaped plates, two cutting knives being inserted between a first and a second plate and two other cutting knives being inserted between said second plate
et une troisieme plaque.and a third plate.

Avantageusement, ledit systeme de lentilles a focale variable comprend deux lentilles montees coulissantes dans un logement cylindrique audit nez de projecteur. De maniere preferee, ledit logement cylindrique comprend une fente dans laquelle coulissent des moyens de commande de deplacement respectifs desdites lentilles, afin de pouvoir commander manuellement le Advantageously, said system of lenses with variable focal length comprises two lenses mounted sliding in a cylindrical housing at said nose of the projector. Preferably, said cylindrical housing comprises a slot in which slide means for controlling the respective displacement of said lenses, in order to be able to manually control the

Dans le cas ou le corps de projecteur ne comporterait pas de tel chassis, l'on peut percer le chassis de la vitre du projecteur et menager Overall, FIGS. 1 to 4 show a headlamp nose 1 adapted to be fixed to a headlamp body (not shown) in order to produce a headlamp with adjustable beam. The projector body, properly speaking, can be any type of simple projector essentially comprising a light source and a reflector. It can be, for example, a projector of known type intended for architectural lighting and illuminations. Such a projector generally comprises a frame making it possible to removably attach to the projector a simple accessory such as, for example, a refractor. This chassis is generally in the form of a frame or a ring provided with four fluted orifices. In the case where the body of the headlamp does not include such a frame, one can pierce the frame of the glass of the headlamp and arrange
des filetages dans chacun des trous. threads in each hole.
En reference aux fires 1, 2 et 4, un nez de projecteur 1 comporte un cylindre 10, de preference de section circulaire, a l'extremite arriere 8 - duquel est soudee une plaque 31 en forme d'anneau dont l'ouverture correspond a l'ouverture du cylindre 10. Outre ['aspect esthetique plaisant qu'elle presente, une section circulaire est particulierement utile pour des projecteurs externes qui peuvent etre soumis a diverges intemperies (pluie, neige...) ainsi qu'a diverges salissures (poussieres, feuilles mortes...) dans la mesure ou elle favorise leur ecoulement ou glissement et reduit ainsi ['exposition et/ou ['accumulation de ces elements par rapport a une section With reference to FIGS. 1, 2 and 4, a headlamp nose 1 comprises a cylinder 10, preferably of circular section, at the rear end 8 - from which is welded a plate 31 in the form of a ring whose opening corresponds to the opening of the cylinder 10. In addition to the pleasant aesthetic appearance which it presents, a circular section is particularly useful for external projectors which can be subjected to various weather conditions (rain, snow ...) as well as to various soils ( dust, dead leaves ...) insofar as it promotes their flow or sliding and thus reduces the exposure and / or the accumulation of these elements with respect to a section

Une fois le reglage desdites lentilles 15, 16 effectue, les manettes de commande 17 et 18 peuvent etre vissees afin de venir porter contre la paroi exterieure du cylindre 10 et de bloquer par consequent les lentilles 15 et 16 Two lenses 15 and 16 constitute a system of variable focal lenses of the “zoom” wind type sliding mounted inside the cylinder 10. More precisely, each of the lenses 15 and 16 is mounted in a respective semi-cylindrical support 13 adapted to slide inside the cylinder 10. A fluted hole is made in each of the supports 13, this hole being adapted to receive a threaded rod adapted to protrude outside through the slot 11 of the cylinder 10. Control levers 17 and 18 wind respectively screwed to the outside of the cylinder 10 on the threaded rods of the supports 13 of the lenses 15 and 16. These control knobs 17, 18 make it possible to control from the outside the sliding of the lenses 15 and 16. Once the adjustment of said lenses 15, 16 carried out, the control levers 17 and 18 can be screwed in order to come to bear against the outer wall of the cylinder 10 and consequently to block the lenses 15 and 16

Ledit disque interface recoit preferentiellement quatre ergots caracteristiques complementaires aux gorges circulaires audit anneau More precisely, the additional interface means allows simple and functional mechanical adaptation to a large number of projectors with fixed optical unit. Said interface means is advantageously produced in the form of an interface disc, the geometric of which varies according to the type of projector intended to accommodate the projector nose assembly 1 ("zoom cutting nose") in accordance with the present invention. Said interface disc preferably receives four characteristic lugs complementary to the circular grooves in said ring

La presente invention propose encore un dispositif original de allow a maximum rotation of + or - 45 of the projector nose 1 or “zoom cutting nose” assembly relative to the projector with fixed optical unit. Advantageously, these four characteristic pins allow a blocking in the angle of the axis of rotation desired at said zoom cutting nose. The present invention also proposes an original device for
decoupe du faisceau a contours variables et multiples. beam cutting with variable and multiple contours.
Generalement, un dispositif de decoupe classique comprend un ensemble de quatre couteaux de decoupe qui permettent un cadrage d'une forme geometrique triangulaire ou quadrangulaire. Ces quatre couteaux vent generalement maintenus par un systeme a friction a deux plans permettant la fermeture complete de deux couteaux opposes dans le meme plan. Au total, la possibilite de reglage consiste a actionner 2 x 2 couteaux sur deux plans distincts, ce qui limite considerablement la possibilite de decoupe du faisceau et, dans tous les cas la limite a des formes geometriques quadrangulaires. En outre, les dispositifs habituels de decoupe ne presentent aucun moyen de blocage des couteaux. Le dispositif de decoupe selon la presente invention permet l'utilisation d'un nombre plus important (typiquement jusquta huit, voire plus) de couteaux a raison de deux couteaux par plan, le principe de construction permettant d'ajouter autant de plans que souhaite sans deterioration substantielle de la qualite de ['image (nettete). Comme precedemment explique, un disque de fond (ou anneau de fixation 34) sert d'appui aux ressorts de compression et comprend quatre Generally, a conventional cutting device comprises a set of four cutting knives which allow framing of a triangular or quadrangular geometric shape. These four knives are generally held by a two-plane friction system allowing the complete closing of two opposing knives in the same plane. In total, the possibility of adjustment consists in operating 2 x 2 knives on two distinct planes, which considerably limits the possibility of cutting the beam and, in all cases the limit to quadrangular geometric shapes. In addition, the usual cutting devices have no means of blocking the knives. The cutting device according to the present invention allows the use of a larger number (typically up to eight, or even more) of knives at the rate of two knives per plane, the construction principle making it possible to add as many planes as desired without substantial deterioration in image quality (sharpness). As previously explained, a bottom disc (or fixing ring 34) serves to support the compression springs and comprises four
inserts femelle permettant le verrouillage et le blocage des couteaux. female inserts for locking and blocking knives.
