Abstract
Description
La présente invention est dans le domaine de l'éclairage et concerne plus particulièrement un projecteur étanche, qui peut être utilisé par exemple sur une scène de spectacles extérieure. Ce projecteur est conçu de manière à permettre de changer la couleur de la lumière émise.The present invention is in the field of lighting and more particularly relates to a waterproof projector, which can be used for example on a stage of outdoor shows. This projector is designed so to change the color of the light emitted.
On connaít différentes sortes de projecteurs capables d'envoyer un faisceau lumineux qui peut être réglé en intensité et auquel on peut faire changer de couleur. Ce changement de couleur peut se faire en utilisant des filtres colorés intercalés dans un faisceau de lumière blanche, filtres qui peuvent être disposés en couronne ou superposés les uns aux autres. Il est aussi possible de le réaliser avec un ensemble de filtres et de miroirs dichroïques sur le faisceau lumineux. Dans la pratique tous ces systèmes avec ses avantages et inconvénients sont plus ou moins efficaces quand ils travaillent à l'intérieur. Dès lors qu'on veut utiliser ces projecteurs non étanches à l'extérieur il faut trouver des solutions pour les protéger des inclémences du temps sans nuire les performances. Si on dispose de projecteurs non étanches, ils seront certainement limités dans leurs mouvements d'orientation par cause des interférences avec les couvertures prévues pour leur propre protection.We know different kinds of projectors capable send a light beam which can be adjusted in intensity and which you can change color. This color change can be done using colored filters inserted in a beam of light white, filters that can be arranged in a crown or superimposed on each other. It is also possible to achieve with a set of filters and mirrors dichroic on the light beam. In practice all of these systems with its pros and cons are more or less effective when they work at inside. When you want to use these projectors not waterproof outside, solutions must be found to protect them from inclement weather without harming them performance. If you have floodlights, they will certainly be limited in their movements orientation due to interference with blankets provided for their own protection.
Le brevet français FR 908.257 présente un appareil destiné aux recherches sous-marines et caractérisé par un projecteur sous-marin formant un ensemble entièrement fermé, d'une étanchéité absolue, résistant efficacement à la pression de l'eau, même aux grandes profondeurs, et présentant une grande robustesse mécanique.French patent FR 908.257 presents an apparatus intended underwater research and characterized by a underwater searchlight forming a whole closed, absolutely waterproof, effectively resistant to water pressure, even at great depths, and with great mechanical robustness.
Le brevet américain US-A-5651 606 concerne un appareil pour être utilisé à l'extérieur qui par conséquent est exposé aux intempéries et qui est utilisé comme projecteur avec de la lumière de grande intensité et comme projecteur orientable pour faire ressortir bâtiments et autres constructions.American patent US-A-5651 606 relates to an apparatus to be used outside which is therefore exposed to the weather and used as a projector with high intensity light and as a spotlight adjustable to highlight buildings and others constructions.
La présente invention tend à pallier à ces difficultés. Elle présente un projecteur étanche et par conséquent qui peut être soumis aux intempéries, qui peut changer des couleurs en raison de l'ensemble de filtres de qu'il dispose et du système d'alimentation électrique indépendant pour chacune des ampoules qu'il comprend.The present invention tends to overcome these difficulties. It has a waterproof projector and therefore may be subject to inclement weather, which may change colors because of the filter set it has and the power supply system independent for each of the bulbs it includes.
La présente invention a pour objet un projecteur étanche comprenant au moins une série de trois ampoules placées sur un cercle avec leurs filtres respectifs et leur système d'alimentation électrique placés à l'intérieur d'un bâti sous forme de coquille composé de deux pièces, une pièce avant présentant un alésage placé devant chaque ampoule et fermé par un verre rendu solidaire de cette pièce avant et une autre pièce arrière, les deux pièces étant reliées par l'intermédiaire d'un joint torique d'étanchéité; un presse-étoupe étant placé sur la pièce arrière de la coquille permet le passage de câbles pour l'alimentation du système électrique, présentant une tige de fixation, caractérisé en ce qu'il comprend une ampoule centrale qui émet de la lumière couleur jaune ou blanche, les faisceaux lumineux émis par les ampoules et l'ampoule centrale étant sensiblement parallèles.The present invention relates to a waterproof projector comprising at least a series of three bulbs placed on a circle with their respective filters and their power supply system placed inside a shell-shaped frame made up of two parts, a front part with a bore placed in front of each bulb and closed by a glass made integral with this front piece and another rear piece, both pieces being connected via an O-ring sealing; a cable gland being placed on the part rear of the shell allows the passage of cables for the power supply of the electrical system, having a rod fixing, characterized in that it comprises a bulb central unit which emits yellow or white light, the light beams emitted by the bulbs and the bulb central being substantially parallel.
Dans un mode d'exécution préféré les filtres relatifs aux ampoules sont en alternance rouges, verts et bleus. Dans ce mode d'exécution, le projecteur peut contenir avantageusement deux séries de trois ampoules dont les filtres sont légèrement plus teintés d'une série à l'autre. Ces filtres sont placés derrière les verres entre les verres et chaque ampoule pour que les faisceaux lumineux soient colorés.In a preferred embodiment, the filters relating to bulbs are alternately red, green and blue. In this execution mode, the projector can contain advantageously two sets of three bulbs, the filters are slightly more tinted from series to the other. These filters are placed behind the glasses between the glasses and each bulb so that the beams bright be colorful.
Le serrage des deux pièces de la coquille se réalise avantageusement avec des vis de fixation qui collaborent pour presser le joint torique entre lesdites pièces.The two parts of the shell are tightened advantageously with fixing screws which collaborate to press the O-ring between said parts.
Pour faciliter le serrage à l'intérieur les ampoules collaborent avec leurs douilles qui sont logées dans une base qui s'appuie contre une plaque de séparation de deux parties, la plaque soutenue par la pièce arrière de la coquille; la base et la plaque sont fixées par des vis à la pièce arrière de la coquille. To facilitate tightening inside the bulbs collaborate with their sockets which are housed in a base which leans against a separation plate of two parts, the plate supported by the back piece of the shell; the base and the plate are fixed by screws the back piece of the shell.
Dans une forme de réalisation préférée le projecteur présente une forme compacte, elle peut être avantageusement un ovoïde ou une sphère.In a preferred embodiment the projector has a compact shape, it can be advantageously an ovoid or a sphere.
Il comprend une tige de fixation avec à sa tête une rotule dont le serrage est effectué par le moyen des vis et d'une base ronde qui épouse la forme de la rotule.It includes a fixing rod with a ball at its head whose tightening is carried out by means of screws and a round base which follows the shape of the patella.
Dans un autre mode d'exécution les câbles d'alimentation électrique peuvent passer à travers la rotule de la tige, ce qui évite d'avoir le presse-étoupe dans la partie arrière de la coquille.In another embodiment the power cables electric can pass through the ball joint of the rod, which avoids having the cable gland in the part back of the shell.
Il est aussi possible de substituer la rotule à la tête de la tige par un jeu de vis et écrou avec une bague d'étanchéité.It is also possible to replace the ball joint at the head of the rod by a set of screws and nut with a ring sealing.
Le dessin annexé représente à titre d'exemple non limitatif une forme préférée de réalisation de l'objet de la présente invention ainsi qu'une variante à cette première.The accompanying drawing shows by way of example not limiting a preferred embodiment of the object of the present invention as well as a variant to this first.
Dans le dessin,
Dans la figure 1 la coquille 1 est composée de deux
pièces, une partie avant 2 et une partie arrière 3. La
pièce avant qui loge dans les alésages 4 les filtres de
couleur 5, maintenus par une bague ressort 6 et d'un verre
étanche 7. Les verres étanches 7 qui servent à protéger
les filtres 5 tiennent à la partie avant 2 par des joints
de colle à la silicone 8. Les filtres 5 et les verres
étanches 7 sont dans l'axe des ampoules 9. Les ampoules 9
sont soutenues par la pression de la partie avant 2 et
branchées dans les douilles d'alimentation 10. Les
douilles d'alimentation 10 sont logées dans une base 11
qui épouse leurs formes ne laissant ressortir que les
contacts électriques pour alimenter les ampoules 9. A
l'arrière de la base 11 se trouve une plaque 12 qui permet
de retenir les douilles 10 et de les appuyer contre la
base 11. La plaque 12 a un trou 13 à l'axe des douilles 10
pour permettre le passage des fils électriques non
représentés dans le dessin. Les vis 14 permettent de
retenir la base 11 et la plaque 12 contre la partie
arrière 3. La partie avant 2 est tenue contre la partie
arrière 3 par le serrage des vis 15 dans la base 11. Un
joint torique 16 se trouve à l'extrémité et sur le
pourtour de la partie arrière 3. Le joint torique 16
permet une étanchéité entre la pièce avant 2 et la pièce
arrière 3. La pièce avant 2 vient écraser le joint torique
16 contre la partie arrière 3. L'écrasement du joint
torique 16 est effectué par les vis 15. Des bagues 17 se
trouvent à l'arrière des têtes des vis 15 pour
l'étanchéité de la pièce avant 2. Les bagues 17 sont
écrasées par le serrage des vis 15 contre la pièce avant
2. Sur la pièce arrière 3 on voit un presse-étoupe étanche
18 qui permet le passage des câbles électriques pour
alimenter les douilles électriques 10. Le presse-étoupe
étanche 18 vient se visser dans la partie arrière 3 et
comprend également une bague 19 qui permet l'étanchéité du
presse-étoupe 18 avec la pièce arrière 3. La bague 19 est
écrasée par le presse-étoupe étanche 18 contre la pièce
arrière 3. Une tige à doubles rotules 20 permet de faire
bouger la pièce arrière 3 sur tous les axes. Cette tige à
rotules 20 vient épouser de forme semblable son logement
dans la pièce 3. Le serrage de la rotule 21 est effectué
par des vis 22 et d'une base ronde 23 qui épouse la forme
de la rotule 21. Il est possible d'avoir un passage à
travers la tige 20 et ses rotules 21, 21a par les câbles
électriques afin de remplacer l'utilisation du presse-étoupe
étanche 18. Il est à noter que si l'on fait passer
les câbles électriques par la tige 20 et ses rotules 21,
21a, il est obligatoire d'avoir un dispositif étanche
semblable aux précédents, non représenté dans le dessin qui
permettrait l'étanchéité de la rotule 21 avec la pièce
arrière 3. A l'autre extrémité de la tige la rotule 21a se
trouve logée dans la base 24 qui permet, de manière
semblable à la pièce arrière 3, de pouvoir faire bouger la
rotule 21a dans tous les axes. Le serrage de la rotule 21a
est effectué par des vis 25 qui traversent la bague ronde
26 et viennent se visser dans la base 24. La bague ronde 26
et la base 24 permettent un bon serrage puisque qu'elles
épousent parfaitement la forme de la rotule 21a. Les trous
27 permettent à la base 24 d'être fixée à un mur ou toutes
autres surfaces plates. Il est possible d'avoir également
un dispositif étanche dans la base 24 pour permettre le
passage des câbles électriques dans la tige 20 et ses
rotules 21, 21a, qui, de nouveau, éviterait l'utilisation
du presse-étoupe étanche 18. Ce mode de réalisation sans
presse-étoupe n'est pas couvert par les revendications mais
fait partie de l'état de la technique et est utile à la
compréhension de l'invention. In Figure 1
Dans la figure 2 nous pouvons apprécier une vue de
face du projecteur avec la partie avant 2 et avec les
ampoules 9 dans les axes des alésages 4 et qui sont en
une
configuration autour d'un perimètre de circle . Dans les
mêmes axes des alésages 4 on peut définir les douilles
électriques 10 ainsi que la position des filtres 5 et les
verres étanches 7 que l'on retrouve dans la figure 1. On
remarque aussi les vis 15 qui permettent le serrage de la
partie avant 2 contre la partie arrière 3 ainsi que
l'ampoule centrale 9a.In figure 2 we can appreciate a view of
front of the projector with the
Dans la figure 3, il est montré une alternative de tige
20a dont la tête supérieure qui collabore avec la pièce
arrière 3 de la coquille 1 est composée d'une vis 28 avec
son écrou 29. Le serrage se produit par l'écrasement d'une
bague d'étanchéité 30. Si on dispose de cette
configuration de tige 20a, l'orientation du projecteur il
faut la faire exclusivement à l'aide de la rotule 21a
logée dans la base 24a.In Figure 3, an alternative rod is shown
20a including the upper head which collaborates with the part
rear 3 of
En définitive, le projecteur 1 composé de six ampoules 9
avec leurs filtres de couleur 5 respectifs et leurs
systèmes d'alimentation individuels permet avec la
collaboration de variateurs de courant de régler
l'intensité lumineuse des faisceaux qui vont traverser les
filtres 5 dont les couleurs de base rouges, vertes et
bleues peuvent être disposés avec nuances de teintes. Par
exemple, si il y a deux jeux de trois filtres rouges verts
et bleus, un jeu pourrait être plus foncé que l'autre, de
façon que le projecteur peut fournir un échantillon de
couleurs très varié. Il faut encore mentionner l'effet
supplémentaire d'augmentation de luminosité apporté par
l'ampoule centrale 9a qui dans le cas précis n'a pas de
filtre.Ultimately, the
