Abstract

The luminous fountain uses an illuminated and decorative jet of water which is formed by a float (2), connected to a power supply by a cable (3), and with a pump (4) to deliver the water through a channel (11) which has a perforated cover (6) at the top. The channel also contains a powerful light (10) which is located immediately below the cover, and the cover is made from a transparent material so that the light shines through it into the jets of water. The lower end of the channel has a perforated base (8) which is surmounted by a rotor (9) driven by the pump. The float itself is made from a rigid housing filled with a material such as a polyurethane foam.

Description

L'invention est relative à une fontaine lumineuse qui trouvera notamment son application dans le domaine décoratif pour être placée dans un bassin afin de créer un jet d'eau illuminé décoratif.The invention relates to a light fountain which will find its application in particular in the decorative field to be placed in a basin in order to create a decorative illuminated water jet.

Si les fontaines ont perdu leur rôle premier en tant que point d'eau, elles sont encore présentes sur de nombreuses places comme élément décoratif. Dans ce cadre, leur magnificence se manifeste sous la forme d'une projection de jet d'eau à grande hauteur. La géométrie des différents jets d'eau peut être arrangée pour former un ensemble harmonieux. Selon l'orientation de chacune des buses d'éjection d'eau sous pression, il est possible d'épanouir plus ou moins les gerbes. Dans certains cas, il est également possible de moduler la pression d'éjection d'eau pour modifier la hauteur du jet.If the fountains have lost their primary role as a water point, they are still present in many places as a decorative element. In this context, their magnificence manifests itself in the form of a projection of water jet at great height. The geometry of the different water jets can be arranged to form a harmonious whole. Depending on the orientation of each of the pressurized water ejection nozzles, it is possible to bloom more or less the sheaves. In some cases, it is also possible to modulate the water ejection pressure to modify the height of the jet.

Les fontaines d'équipements collectifs sont généralement de type fixe c'est-à-dire qu'elles comprennent un bassin au centre duquel sont placées des buses de projection d'eau alimentées par une station de pompage qui s'approvisionne dans le bassin. Ainsi, l'ensemble tourne en circuit fermé et seules les pertes d'eau doivent être compensées.The collective equipment fountains are generally of the fixed type, that is to say that they comprise a basin at the center of which are placed water spray nozzles supplied by a pumping station which supplies itself in the basin. Thus, the assembly rotates in a closed circuit and only the water losses have to be compensated.

L'illumination nocturne de la fontaine est généralement assurée au moyen de projecteurs placés au fond du bassin ou à l'extérieur et qui sont dirigés vers les jets d'eau. Cette disposition est satisfaisante car, si l'ensemble de la fontaine est éclairé, le bassin constitue un élément décoratif d'importance qui ne nuit pas à l'esthétique de l'ensemble. Une illumination globale est donc acceptable encore que l'élément marquant d'une fontaine soit plus spécialement l'ensemble des gerbes d'eau.The nocturnal illumination of the fountain is generally ensured by means of projectors placed at the bottom of the basin or outside and which are directed towards the water jets. This arrangement is satisfactory because, if the entire fountain is lit, the basin constitutes an important decorative element which does not harm the aesthetics of the whole. A global illumination is therefore acceptable even if the defining element of a fountain is more especially the set of water sprays.

Dans un cadre privé, la réalisation de fontaines est rare car très coûteuse. En effet, il faut tout d'abord disposer d'un bassin de surface importante pour recueillir l'eau projetée et le coût d'une telle construction est peu compatible avec les occasions limitées d'offrir son fonctionnement en spectacle. Il faut d'ailleurs remarquer à ce sujet que c'est au cours d'invitations en soirée que le spectacle d'une fontaine lumineuse pourrait être le plus apprécié.In a private setting, the realization of fountains is rare because very expensive. Indeed, it is first necessary to have a large surface pool to collect the projected water and the cost of such a construction is hardly compatible with the limited opportunities to offer its performance. It should also be noted in this regard that it is during evening invitations that the spectacle of a light fountain could be most appreciated.

Les fabricants de fontaines ont mis au point des équipements mobiles destinés à être immergés dans des piscines. La solution offre de nombreux avantages, tout d'abord, le bassin de la piscine peut parfaitement être employé pour les plaisirs nautiques traditionnels. Aucune transformation ou modification pour une adaptation à la fontaine n'est nécessaire. Les dimensions conventionnelles d'un bassin de piscine conviennent parfaitement pour recueillir des projections d'eau.The manufacturers of fountains have developed mobile equipment intended to be immersed in swimming pools. The solution offers many advantages, first of all, the swimming pool basin can be perfectly used for traditional nautical pleasures. No transformation or modification for an adaptation to the fountain is necessary. The conventional dimensions of a swimming pool are ideal for collecting water splashes.

Ces fontaines mobiles sont formées d'un flotteur de soutien d'une pompe immergée qui dirige l'eau sous pression vers une buse de fontaine. L'ensemble est alimenté par un câble électrique traversant le bassin.These mobile fountains are formed by a float supporting a submerged pump which directs the pressurized water to a fountain nozzle. The whole is supplied by an electric cable crossing the basin.

Pour permettre les illuminations nocturnes, la bouée est également équipée d'un projecteur fixé à proximité de la buse et qui est dirigée vers les gerbes d'eau. Plusieurs inconvénients sont liés à cette technique de construction. En particulier, l'éclairage ne se concentre pas sur les projections d'eau mais il y a diffusion et, par exemple, le dispositif de pompage est visible ainsi que le fond de la piscine, ce qui nuit à l'esthétique de l'ensemble.To allow nocturnal illuminations, the buoy is also equipped with a projector fixed near the nozzle and which is directed towards the sheaves of water. Several drawbacks are linked to this construction technique. In particular, the lighting does not focus on splashing water but there is diffusion and, for example, the pumping device is visible as well as the bottom of the pool, which affects the aesthetics of the together.

Le projecteur n'est pas protégé et si la fontaine est manipulée sans précaution, il y a des risques d'endommagement. Ces risques sont d'autant plus graves que s'il y a rupture de l'étanchéité du projecteur, et que celui-ci est directement alimenté par la tension du secteur, il y a un danger d'électrocution. Ensuite, cette disposition nécessite d'entretenir régulièrement le projecteur notamment pour enlever la formation de mousse qui a tendance à le recouvrir.The projector is not protected and if the fountain is handled without care, there is a risk of damage. These risks are all the more serious if there is a break in the watertightness of the projector, and the latter is directly supplied by the mains voltage, there is a danger of electric shock. Then, this arrangement requires regular maintenance of the projector in particular to remove the formation of foam which tends to cover it.

Quoique des progrès importants ont été accomplis avec l'élaboration des fontaines mobiles, le dispositif d'éclairage auxiliaire suscite néanmoins quelques problèmes tant dans son fonctionnement que par l'effet décoratif qu'il procure.Although significant progress has been made with the development of mobile fountains, the auxiliary lighting device nevertheless raises some problems both in its operation and in the decorative effect it provides.

Le but principal de la présente invention est de présenter une fontaine lumineuse dans laquelle il y a une coopération totale du dispositif d'éclairage avec le mécanisme de pompage pour former un ensemble harmonieux.The main object of the present invention is to present a light fountain in which there is total cooperation of the lighting device with the pumping mechanism to form a harmonious whole.

En particulier, l'éclairage est localisé au niveau des gerbes d'eau sans qu il y ait diffusion de lumière dans le bassin ou dans les organes de la fontaine.In particular, the lighting is localized at the level of water sprays without any diffusion of light in the basin or in the organs of the fountain.

Des effets lumineux spéciaux peuvent être produits grâce à une injection directe de faisceaux lumineux au sein de l'écoulement liquide.Special light effects can be produced by direct injection of light beams into the flow liquid.

Un autre but de la présente invention est de présenter une fontaine lumineuse qui dispose d'une grande sécurité de fonctionnement. Le projecteur est entièrement incorporé dans la fontaine qui forme un rempart et le met à l'abri d'actions mécaniques extérieures. En outre, des précautions particulières sont prises en ce qui concerne l'alimentation électrique de la fontaine pour écarter tout risque d'électrocution.Another object of the present invention is to present a light fountain which has great operational safety. The projector is fully incorporated in the fountain which forms a rampart and shelters it from external mechanical actions. In addition, special precautions are taken with regard to the electrical supply to the fountain to avoid any risk of electric shock.

La fontaine lumineuse ne nécessite aucun entretien notamment en ce qui concerne le nettoyage du projecteur. Un phénomène d'auto-nettoyage est créé pour éviter toute formation de mousse sur sa surface, ce qui nuirait à la puissance d'émission lumineuse.The light fountain requires no maintenance, particularly with regard to cleaning the projector. A self-cleaning phenomenon is created to avoid any formation of foam on its surface, which would adversely affect the power of light emission.

La technique de fabrication utilisée pour construire la fontaine lumineuse de la présente invention permet d'obtenir un produit de haute qualité et performant, ceci avec un coût de fabrication modéré afin de permettre une large diffusion du produit.The manufacturing technique used to build the light fountain of the present invention makes it possible to obtain a high quality and efficient product, this with a moderate manufacturing cost in order to allow a wide distribution of the product.

D'autres buts et avantages de la présente invention apparaitront au cours de la description suivante qui n'est donnée qu'à titre indicatif.Other objects and advantages of the present invention will appear during the following description which is given only for information.

La fontaine lumineuse destinée à être placée dans un bassin pour créer un jet d'eau illuminé décoratif, qui comprend un flotteur relié à une source d'énergie par un câble, une pompe qui refoule l'eau dans une veine terminée par un ajutage perforé et un projecteur d'éclairage, est caractérisée par le fait que le projecteur est disposé dans la veine liquide à proximité immédiate de l'ajutage.The light fountain intended to be placed in a basin to create a decorative illuminated water jet, which includes a float connected to an energy source by a cable, a pump which pumps water into a vein terminated by a perforated nozzle and a lighting projector, is characterized in that the projector is arranged in the liquid stream in the immediate vicinity of the nozzle.

L'invention sera mieux comprise à la lecture de la description suivante accompagnée de dessins en annexe parmi lesquels:

  • - la figure 2 représente la fontaine lumineuse en vue de dessus,
  • - la figure 3 schématise, en vue de coupe, la constitution interne du projecteur,

La présente invention vise une fontaine lumineuse destinée à être placée dans un bassin pour créer des jets d'eau illuminés décoratifs.The present invention relates to a light fountain intended to be placed in a basin to create illuminated water jets decorative.

Le spectacle offert par une fontaine est très recherché sur le plan ornemental, ce qui explique que de nombreuses places en sont dotées.The spectacle offered by a fountain is highly sought after ornamentally, which explains why many places have it.

Les installations fixes traditionnelles comprennent un bassin de récupération des eaux projetées par une buse alimentée par l'intermédiaire d'une station de pompage. Cette conception fixe convient parfaitement aux réalisations publiques. Par contre, dans un cadre privé, les dimensions nécessaires du bassin sont difficilement compatibles avec l'étendue traditionnelle des jardins.Traditional fixed installations include a catchment basin for water projected by a nozzle supplied by a pumping station. This fixed design is perfectly suited to public works. On the other hand, in a private setting, the necessary dimensions of the pond are hardly compatible with the traditional extent of the gardens.

Les fabricants de fontaines ont élaboré des dispositifs autonomes destinés à être plongés par exemple dans une piscine afin de transformer cette dernière en bassin de fontaine. L'avantage est que l'opération est réversible et peut très rapidement être réalisée. Aucune tranformation de la piscine n'est nécessaire et même une faible profondeur convient.The fountain manufacturers have developed autonomous devices intended to be immersed, for example, in a swimming pool in order to transform the latter into a fountain basin. The advantage is that the operation is reversible and can be carried out very quickly. No transformation of the pool is necessary and even a shallow depth is suitable.

Ces fontaines autonomes comprennent un flotteur de soutien d'une pompe qui aspire l'eau du bassin et la refoule vers une ou plusieurs buses d'éjection. La fontaine est alimentée par une source d'énergie extérieure au moyen d'un câble.These stand-alone fountains include a float supporting a pump which draws water from the basin and delivers it to one or more ejection nozzles. The fountain is supplied by an external energy source by means of a cable.

Pour animer les soirées, la clientèle réclame souvent aux constructeurs l'adjonction d'un éclairage pour illuminer les gerbes d'eau. Les constructeurs sont donc amenés à équiper leur flotteur d'un projecteur auxiliaire dirigé vers le haut qui illumine par la base les différents jets d'eau.To liven up the evenings, customers often ask the builders to add lighting to illuminate the spray of water. Manufacturers are therefore required to equip their float with an auxiliary projector directed upwards which illuminates the various water jets from the bottom.

Plusieurs inconvénients sont liés à cette technique d'éclairage. Tout d'abord, les rayons lumineux issus du projecteur ne se concentrent pas sur les jets d'eau mais diffusent la lumière sur l'environnement. Ensuite, le projecteur n'est pas protégé mécaniquement vis-à-vis des chocs extérieurs et au cours de manipulations, il peut facilement être endommagé.Several drawbacks are linked to this lighting technique. First of all, the light rays coming from the projector do not concentrate on the water jets but scatter the light on the environment. Then, the projector is not mechanically protected against external shocks and during handling, it can easily be damaged.

Enfin, on assiste très fréquemment à un phénomène de développement de mousse verte à la surface du projecteur qui doit être entretenu régulièrement pour conserver ses caractéristiques.Finally, there is very often a phenomenon of development of green foam on the surface of the projector which must be maintained regularly to maintain its characteristics.

La diffusion lumineuse est assurément le défaut le plus important car elle fait perdre du contraste au spectacle. De plus, le bassin de la piscine se trouve partiellement éclairé, ce qui constitue un handicap étant donné que, dans cette fonction de fontaine, il joue un rôle technique et non artistique.The light diffusion is undoubtedly the most important defect because it makes the spectacle lose contrast. In addition, the swimming pool basin is partially lit, which constitutes a handicap since, in this function of fountain, it plays a technical and not an artistic role.

La présente invention se propose précisément d'apporter une solution à ces différents problèmes grâce à un agencement particulier des différents organes.The present invention specifically proposes to provide a solution to these various problems by means of a particular arrangement of the various members.

La figure 1 schématise, en vue de coupe, la fontaine lumineuse 1 réalisée selon un mode préférentiel de construction. La fontaine lumineuse 1 comprend un flotteur 2 destiné à maintenir l'ensemble de la fontaine 1 en surface du bassin dans lequel elle est plongée.Figure 1 shows schematically, in sectional view, the light fountain 1 produced according to a preferred mode of construction. The light fountain 1 comprises a float 2 intended to hold the whole of the fountain 1 on the surface of the basin in which it is immersed.

Le flotteur 2 est relié à une source d'énergie électrique extérieure par l'intermédiaire d'un câble 3. Ce câble 3 assure en outre le lestage du flotteur 2 et son ancrage au centre du bassin.The float 2 is connected to an external electrical energy source by means of a cable 3. This cable 3 also ensures the ballasting of the float 2 and its anchoring in the center of the basin.

La fontaine 1 comprend également une pompe 4. Cette pompe 4 est placée dans une gaine 5 intérieure au flotteur 2 qui est traversée verticalement par la gaine 5. La pompe 4 aspire l'eau à la base du flotteur 2 et la refoule dans la gaine 5 vers le haut pour créer une veine liquide sous pression. La gaine 5 est terminée à sa partie supérieure par un ajutage 6 perforé. Les perforations 7 de l'ajutage créent autant de jets d'eau et font office de buses d'éjection. Selon la disposition et l'orientation des perforations 7, on modifie l'épanouissement et la forme de la gerbe d'eau. L'ajutage perforé 6 est usiné selon l'effet esthétique recherche.The fountain 1 also comprises a pump 4. This pump 4 is placed in a sheath 5 inside the float 2 which is crossed vertically by the sheath 5. The pump 4 draws water from the base of the float 2 and discharges it into the sheath 5 upward to create a pressurized liquid vein. The sheath 5 is terminated at its upper part by a perforated nozzle 6. The perforations 7 of the nozzle create as many water jets and act as ejection nozzles. Depending on the arrangement and orientation of the perforations 7, the development and the shape of the spray of water are modified. The perforated nozzle 6 is machined according to the desired aesthetic effect.

L'aspiration de l'eau à la base du flotteur 2 se fait au-travers d'orifices 8 qui protègent la turbine 9 de la pompe 4 contre l'introduction de corps étrangers durs.The suction of water at the base of the float 2 is done through orifices 8 which protect the turbine 9 of the pump 4 against the introduction of hard foreign bodies.

En outre, la fontaine lumineuse 1 comprend un projecteur 10 d'éclairage incorporé. Ce projecteur 10 est disposé dans la veine liquide 11 au centre de la gaine 5 à proximité immédiate de l'ajutage perforé 6. Cette disposition particulière procure un effet spectaculaire. En effet, les rayons lumineux sont emprisonnés au sein même de la gerbe d'eau, ce qui procure un contraste unique. Contrairement aux gênes apportées par l'utilisation d'un projecteur extérieur, selon l'invention, seuls les jets d'eau sont illuminés, aucun éclairage parasite ne se manifeste.In addition, the light fountain 1 includes a built-in lighting projector 10. This projector 10 is disposed in the liquid stream 11 at the center of the sheath 5 in the immediate vicinity of the perforated nozzle 6. This particular arrangement provides a spectacular effect. Indeed, the light rays are trapped within the very spray of water, which provides a unique contrast. Unlike the annoyance caused by the use of an external projector, according to the invention, only the water jets are illuminated, no stray lighting appears.

La direction des rayons lumineux issus de l'optique du projecteur 10 doit correspondre sensiblement à la direction axiale des perforations 7 de l'ajutage 6, ceci pour permettre aux rayons lumineux d'être canalisés dans les jets d'eau.The direction of the light rays coming from the optics of the projector 10 must correspond substantially to the axial direction of the perforations 7 of the nozzle 6, this to allow the light rays to be channeled in the water jets.

De préférence, les axes des perforations 7 de l'ajutage 6 doivent être orientés et concourrants avec le foyer de l'optique du projecteur 10.Preferably, the axes of the perforations 7 of the nozzle 6 must be oriented and concurrent with the focal point of the headlight optics 10.

Il est également possible d'utiliser un ajutage 6 transparent pour renforcer l'illumination de la gerbe d'eau. En prenant par exemple une matière plastique teintée pour la fabrication de l'ajutage 6, il est possible de créer des phénomènes de couleurs étant donné que les rayons lumineux traversant directement l'ajutage par les perforations 7 ne sont pas filtrés contrairement à ceux qui traversent l'ajutage 6.It is also possible to use a transparent nozzle 6 to enhance the illumination of the spray of water. By taking for example a tinted plastic material for the manufacture of the nozzle 6, it is possible to create color phenomena since the light rays passing directly through the nozzle through the perforations 7 are not filtered unlike those which pass through the nozzle 6.

Le flotteur 2 est de forme annulaire tel que cela est illustré à la figure 2 en vue de dessus, il est traversé dans sa partie centrale par la gaine 5. Le flotteur 2 a un profil extérieur en forme de double tronc de cône inversé. Le niveau d'eau doit sensiblement arriver à l'endroit de la jonction des deux troncs de cône. Cette forme géométrique particulière procure une bonne stabilité verticale de flottaison à la fontaine 1. Elle est peu sensible au vent et aux petites vagues.The float 2 is of annular shape as illustrated in FIG. 2 in plan view, it is crossed in its central part by the sheath 5. The float 2 has an external profile in the form of a double inverted truncated cone. The water level must substantially reach the point where the two truncated cones meet. This particular geometric shape provides good vertical flotation stability to the fountain 1. It is not very sensitive to wind and small waves.

En ce qui concerne la construction mécanique de la fontaine, l'ensemble des organes intérieurs, qu'il s'agisse de la pompe 4 ou du projecteur 10 sont fixés sur des tirants 12. Ces tirants 12 prennent appui à la partie inférieure directement sur la coque 13 du flotteur 2. A la partie supérieure, les tirants 12 s'appuient sur l'ajutage perforé 6 qui est ainsi appliqué contre la gaine 5.With regard to the mechanical construction of the fountain, all of the internal members, whether it is the pump 4 or the projector 10, are fixed on tie rods 12. These tie rods 12 bear on the lower part directly on the shell 13 of the float 2. At the upper part, the tie rods 12 are supported on the perforated nozzle 6 which is thus applied against the sheath 5.

La gaine 5 ne s'applique pas directement sur la coque 13 du flotteur 2 dans la partie inférieure de la fontaine 1, mais une bride d'aspiration 14 est interposée dans le fond de la coque 13. La pompe 4 est centrée sur la bride 14 par l'intermédiaire du diffuseur 23 dont le rôle est également de guider les filets d'eau sortant de la turbine 9 vers la veine liquide 11.The sheath 5 does not apply directly to the shell 13 of the float 2 in the lower part of the fountain 1, but a suction flange 14 is interposed in the bottom of the shell 13. The pump 4 is centered on the flange 14 via the diffuser 23, the role of which is also to guide the streams of water leaving the turbine 9 towards the liquid stream 11.

Le volume intérieur de la coque 13 disposée autour de la gaine 5, est rempli de mousse telle qu'une mousse de polyuréthane par exemple.The interior volume of the shell 13 arranged around the sheath 5 is filled with foam such as polyurethane foam for example.

Le centrage du projecteur 10 est automatiquement assuré puisqu' il prend appui sur les mêmes tirants 11 qui servent à la fixation de l'ajutage perforé 6.The centering of the headlight 10 is automatically ensured since it rests on the same tie rods 11 which are used for fixing the perforated nozzle 6.

La figure 3 illustre, en vue de coupe, la construction mécanique du projecteur 10. Celle-ci comporte un compartiment étanche 15 qui renferme l'optique 26 du projecteur. Le compartiment 15 est formé d'une virole extérieure 27 pincée entre deux flasques 17 et 18 appliqués l'un vers l'autre par l'intermédiaire d'écrous 19 placés sur les tirants 12. Le flasque 18 est ajouré et une glace 20 est interposée entre le flasque 18 et la virole 27 pour permettre le passsage des rayons lumineux issus de l'optique 26. Deux joints en élastomère 24, 25 assurent l'étanchéité entre la virole 27 d'une part et d'autre part le flasque 17 et la glace 20.Figure 3 illustrates, in section view, the construction headlamp mechanics 10. This comprises a sealed compartment 15 which contains the headlamp optics 26. The compartment 15 is formed by an outer ferrule 27 pinched between two flanges 17 and 18 applied towards each other by means of nuts 19 placed on the tie rods. The flange 18 is perforated and a glass 20 is interposed between the flange 18 and the ferrule 27 to allow the passage of light rays from the optics 26. Two elastomer seals 24, 25 seal between the ferrule 27 on the one hand and the flange 17 on the other hand and ice 20.

Un presse-étoupe étanche 21 relié à un câble électrique qui traverse le flasque 17 assure l'alimentation du dispositif d'éclairage de l'optique 26.A sealed cable gland 21 connected to an electric cable which passes through the flange 17 supplies the lighting device for the optics 26.

Au cas où un ensemble de trois tirants 12 est utilisé pour assurer la fixation des différents organes, de préférence, la forme des flasques est profilée selon une géométrie triangulaire telle qu'illustrée à la figure 4 pour le flasque 18 de sorte à faciliter l'écoulement liquide autour du projecteur. De même si quatre tirants étaient utilisés, la forme des flasques serait profilée avec quatre lobes.In the case where a set of three tie rods 12 is used to secure the various members, preferably, the shape of the flanges is profiled according to a triangular geometry as illustrated in FIG. 4 for the flange 18 so as to facilitate the liquid flow around the projector. Similarly, if four tie rods were used, the shape of the flanges would be profiled with four lobes.

L'alimentation du moteur électrique de la pompe 4 et du projecteur 10 est assurée au moyen d'un câble 3 relié à la fontaine 1 par l'intermédiaire d'un connecteur coaxial étanche 22 tel qu'illustré à la figure 1. Ce connecteur 22 permet de débrancher le câble 3 lorsque la fontaine 1 n'est pas en service. De préférence, la tension utilisée pour l'alimentation de la pompe 4 et du projecteur 10 est très basse, de l'ordre de 12 volts, ce qui écarte tout risque d'accident d'électrocution même en cas d'éclatement de l'ampoule ou d'entrée d'eau accidentelle.The electric motor of the pump 4 and of the projector 10 is supplied by a cable 3 connected to the fountain 1 by means of a sealed coaxial connector 22 as illustrated in FIG. 1. This connector 22 allows the cable 3 to be disconnected when the fountain 1 is not in use. Preferably, the voltage used to supply the pump 4 and the projector 10 is very low, of the order of 12 volts, which eliminates any risk of electrocution accident even in the event of bursting of the bulb or accidental water inlet.

Le projecteur 10 est entièrement abrité vis-à-vis des agressions mécaniques extérieures. De plus, le verre 20 est constamment lavé par la circulation d'eau, ce qui empêche la formation de mousse opaque comme cela est traditionnellement rencontré avec les projecteurs extérieurs. Aucun nettoyage n'est nécessaire, ce qui facilite l'entretien de l'ensemble.The projector 10 is entirely sheltered from external mechanical attack. In addition, the glass 20 is constantly washed by the circulation of water, which prevents the formation of opaque foam as is traditionally encountered with exterior projectors. No cleaning is necessary, which facilitates the maintenance of the assembly.

D'autres mises en oeuvre de la présente invention, à la portée de l'Homme de l'Art, auraient également pu être envisagées sans pour autant sortir du cadre de celle-ci.Other implementations of the present invention, within the reach of ordinary skill in the art, could also have been envisaged without departing from the scope thereof.
