Description

Lampe montgolfière. Balloon lamp.
L'invention concerne la réalisation d'une lampe d'ambiance destinée à animer un salon ou une chambre d'enfant, en diffusant la lumière à partir d'une source mobile.The invention relates to the production of a mood lamp intended to enliven a living room or a child's bedroom, by diffusing light from a mobile source.
Selon l'invention, la source mobile est animée par le flux d'air chaud que génère l'ampoule.According to the invention, the mobile source is driven by the flow of hot air generated by the bulb.
On connaît un principe de lampe animée fonctionnant sur ce principe, il est mis en œuvre avec une hélice solidaire d'un cylindre portant un motif transparent, tournant librement au- dessus de l'ampoule. Ce principe est issu d'une longue tradition.There is a principle of an animated lamp operating on this principle, it is implemented with a propeller secured to a cylinder carrying a transparent pattern, freely rotating above the bulb. This principle comes from a long tradition.
Selon le principe original de l'invention l'air chauffé par l'ampoule de la lampe remplit une montgolfière, qui une fois totalement remplie décolle et monte jusqu'au plafond de la pièce. La lampe possède une base qui confine un flux d'air chaud et projette un faisceau lumineux vers la montgolfière, celle ci diffuse la lumière dans la pièce. Quand la montgolfière est refroidie, elle retombe vers sa base qui réchauffe l'air qu'elle contient. Elle redécolle alors. Le cycle continue indéfiniment et anime la pièce, la lumière varie ce qui crée une ambiance.According to the original principle of the invention, the air heated by the bulb of the lamp fills a hot air balloon, which once completely filled takes off and rises to the ceiling of the room. The lamp has a base which confines a flow of hot air and projects a light beam towards the hot air balloon, which diffuses the light in the room. When the hot air balloon is cooled, it falls back towards its base which heats the air which it contains. She then takes off again. The cycle continues indefinitely and enlivens the room, the light varies which creates an atmosphere.
L'invention présentée figure 1 , comporte trois parties,The invention presented in FIG. 1, has three parts,
- Une base 1 1 sorte de manche à air contient l'ampoule, est connecté à la tension secteur domestique ou bien à une source basse tension.- A base 1 1 kind of wind sock contains the bulb, is connected to the domestic mains voltage or to a low voltage source.
- Un guide 12 dans la base 11 monte verticalement. Il est terminé par une butée d'arrêt. - Une montgolfière 13 présentée dégonflée, sorte de sac très léger, se remplit d'air et diffuse la lumière projetée par la lampe.- A guide 12 in the base 11 rises vertically. It ends with a stopper. - A hot air balloon 13 presented deflated, a sort of very light bag, fills with air and diffuses the light projected by the lamp.
Selon une première caractéristique originale de l'invention, le guide 12 est une tige rectiligne. De plus elle est terminée par une butée réglable en hauteur. Elle est fichée dans la base de la lampe, par exemple dans une douille.According to a first original characteristic of the invention, the guide 12 is a straight rod. In addition, it is terminated by a height-adjustable stop. It is stuck in the base of the lamp, for example in a socket.
Elle est par exemple réalisée dans un matériau élastique et flexible comme de la fibre de verre ou de la fibre de carbonne. Une telle tige de longueur importante, jusqu'à plusieurs mètres, présente l'avantage de pouvoir être conditionnée en rouleau de diamètre modeste, de l'ordre de 30 cm, sans casser ni mémoriser la flexion.It is for example made of an elastic and flexible material such as fiberglass or carbon fiber. Such a rod of considerable length, up to several meters, has the advantage of being able to be packaged in a roll of modest diameter, of the order of 30 cm, without breaking or memorizing the flexion.
Déroulée, la tige reprend sa rectitude initiale. Ainsi cette tige est conditionnée avec la lampe dans une boite dont la dimension est adaptée au réseau de la distribution commercial classique.Unrolled, the stem returns to its initial straightness. Thus this rod is packaged with the lamp in a box whose size is adapted to the conventional commercial distribution network.
Selon une deuxième caractéristique originale de réalisation de l'invention, la base de lampe 1 1 comporte également des bras 15 ou une coupelle qui soutiennent la montgolfière vide et recueillent le film.According to a second original characteristic of the invention, the lamp base 1 1 also includes arms 15 or a cup which support the empty hot air balloon and collect the film.
Selon une troisième caractéristique principale de l'invention , la base de lampe ajustée à la montgolfière dépliée réalise une poche d'air confiné, étanche. Selon l'invention il un flux convectif fermé est optimisé pour chauffer l'air confiné dans la montgolfière. Cela est réalisé par une disposition et une combinaison de caractéristiques de la base et de ses composants, et de la montgolfière : - la base 11 de la lampe est sensiblement cylindrique d'axe vertical, elle est réalisée dans un matériau opaque ou semi-translucide, résistant à la chaleur et de préférence peu conducteur thermique. Elle peut être réalisée en plastique, par exemple polyester ou poly carbonate.According to a third main characteristic of the invention, the lamp base adjusted to the unfolded hot air balloon achieves a pocket of confined, airtight air. According to the invention, a closed convective flow is optimized to heat the air confined in the balloon. This is achieved by an arrangement and a combination of characteristics of the base and its components, and of the balloon: - The base 11 of the lamp is substantially cylindrical with a vertical axis, it is made of an opaque or semi-translucent material, heat resistant and preferably not very heat conductive. It can be made of plastic, for example polyester or poly carbonate.
- La partie supérieure est ouverte et laisse apparaître une grille 17, dans le creux de bras ou d'une coupelle pour recueillir la montgolfière 13 dégonflée. - La partie inférieure présente des entrés d'air sur le pourtour, à la base.- The upper part is open and reveals a grid 17, in the hollow of an arm or a cup to collect the deflated hot air balloon 13. - The lower part has air inlets on the periphery, at the base.
Cette géométrie optimise l'efficacité de la montgolfière et sa sûreté d'utilisation :This geometry optimizes the efficiency of the balloon and its safety of use:
La condition d'envol est fixée par la température moyenne de l'air emprisonné. Pour une montgolfière de taille modeste environ 50 cm, en polyester de faible épaisseur, environ 6 microns, la température d'envol peut nécessiter 100 ° C.The flight condition is determined by the average temperature of the trapped air. For a balloon of modest size about 50 cm, in thin polyester, about 6 microns, the flight temperature may require 100 ° C.
Une telle température présente un inconfort et un risque pour l'usager.Such a temperature presents discomfort and a risk for the user.
Aussi, l'optimisation consiste à porter l'air prisonnier de la montgolfière à une température élevée, sans que l'air diffusé par la lampe découverte n'atteigne une température critique.Optimization also consists in bringing the air trapped in the hot air balloon to a high temperature, without the air diffused by the discovered lamp reaching a critical temperature.
Cela est organisé par l'échange convectif cyclique entre la base et la montgolfière; décrit figure 2.This is organized by the cyclic convective exchange between the base and the balloon; described in figure 2.
En effet, la lampe prolonge la montgolfière et réalise une étanchéité partielle, la seule ouverture étant située à la base de la lampe. L'air le plus chaud 21 s'élevant du radiateur monte verticalement au centre de la montgolfière 23 expansée. L'air refroidi chassé 22, redescend par les cotés, jusqu'à la base de la lampe, à l'entrée du radiateur, sans toutefois s'échapper car il reste plus léger que l'air ambiant. ( L'entrée d'air 24 de la base est au point inférieur ).Indeed, the lamp extends the hot air balloon and achieves a partial seal, the only opening being located at the base of the lamp. The warmest air 21 rising from the radiator rises vertically to the center of the expanded hot air balloon 23. The cooled expelled air 22, descends from the sides, to the base of the lamp, at the entrance of the radiator, without however escaping because it remains lighter than the ambient air. (The air inlet 24 of the base is at the lower point).
Il est alors réchauffé et parcourt un nouveau cycle. A chaque cycle, la température de l'air s'élève de quelques degrés, et après un nombre indéterminé de cycles, la température moyenne de décollage est atteinte.It is then reheated and goes through a new cycle. At each cycle, the air temperature rises a few degrees, and after an indefinite number of cycles, the average take-off temperature is reached.
Par ce procédé lié à la forme de la base, de l'embouchure ajustée de la montgolfière et des entrées d'air, ainsi qu'aux caractéristiques de la lampe et des radiateurs, l'air confiné dans la montgolfière s'échauffe progressivement.By this process linked to the shape of the base, the adjusted mouth of the hot air balloon and the air inlets, as well as to the characteristics of the lamp and the radiators, the air confined in the hot air balloon gradually heats up.
Ainsi selon l'inventionThus according to the invention
- la base de la lampe est sensiblement cylindrique, - son diamètre est entre le tiers et le cinquième du diamètre de la montgolfière sensiblement sphérique.- the base of the lamp is substantially cylindrical, - its diameter is between one third and one fifth of the diameter of the balloon substantially spherical.
- l'embouchure de la lampe et de la montgolfière s'ajustent avec étanchéité.- the mouth of the lamp and the hot air balloon adjust with tightness.
- l'entrée d'air est située au pied de la base, au point le plus bas sur le pourtour.- the air inlet is located at the foot of the base, at the lowest point on the perimeter.
Ce procédé permet donc également de réduire la puissance nécessaire au décollage de la montgolfière, la chaleur de la lampe étant recyclée. Dès que la montgolfière est décollée, le cycle est interrompu et l'air qui circule se renouvelle. Il est frais car il est aspiré à la base de la lampe et vient refroidir le radiateur.This process therefore also makes it possible to reduce the power required for takeoff of the balloon, the heat of the lamp being recycled. As soon as the balloon takes off, the cycle is interrupted and the circulating air is renewed. It is cool because it is sucked in at the base of the lamp and cools the radiator.
Le flux d'air le plus chaud 31 figure 3 ne passe qu'une fois sur le radiateur, le reste de la base est refroidi par un courant d'air frais 32.The hottest air flow 31 in FIG. 3 only passes once over the radiator, the rest of the base is cooled by a stream of fresh air 32.
Dés la montgolfière décollée, la base refroidit et l'air diffusé est moins chaud. I l ne s'élève que de quelques degrés à la traversée du radiateur, et n'expose par l'usager à la température de confinée dans la montgolfière.As soon as the hot air balloon takes off, the base cools and the diffused air is less hot. I t rises only a few degrees at the crossing of the radiator, and does not expose the user to the temperature confined in the hot air balloon.
Deux composants contribuent à l'optimisation du réchauffage de l'air :Two components contribute to the optimization of air heating:
Selon une quatrième caractéristique principale de l'invention l'ampoule 14 située dans la base 11 est tubulaire du type halogène faible tension ou tension domestique. Elle est placée verticalement. Sa puissance est de 100 à 1000 W, déterminée en fonction de la taille et du poids de la montgolfière.According to a fourth main characteristic of the invention, the bulb 14 located in the base 11 is tubular of the low voltage or household voltage halogen type. It is placed vertically. Its power is from 100 to 1000 W, determined according to the size and weight of the balloon.
Selon une cinquième caractéristique principale de l'invention la lampe tubulaire est placée au centre d'un radiateur 16 absorbant l'énergie lumineuse et diffusant de la chaleur.According to a fifth main characteristic of the invention, the tubular lamp is placed in the center of a radiator 16 absorbing light energy and diffusing heat.
Un tel convertisseur de l'énergie lumineuse en chaleur est par exemple réalisé en feuillard d'acier bruni ou en aluminium noirci plié en soufflet ( en accordéon ) autour de la lampe. Il présente ainsi une surface exposée à l'air importante, il répartit le flux lumineux absorbé sur une surface importante dans un volume restreint, et à moindre poids. De plus, il ne stocke que peu de chaleur étant léger et conducteur thermique, ainsi il est rapidement efficace. Enfin, il ne présente pas d'entrave à la convection naturelle verticale de l'air.Such a converter of light energy into heat is for example made of burnished steel strip or of blackened aluminum folded in a bellows (in accordion) around the lamp. It thus has a large surface exposed to air, it distributes the light flux absorbed over a large surface in a small volume, and at a lower weight. In addition, it only stores a few heat being light and thermal conductor, so it is quickly effective. Finally, it does not obstruct the natural vertical convection of air.
I l peut également être réalisé par plusieurs cylindres métalliques ajourés, concentriques, centrés sur la lampe, et de diamètres croissants. Chacun absorbant une fraction du rayonnement, ces cylindres présentent une surface de dissipation importante dans un volume restreint.I t can also be achieved by several perforated metal cylinders, concentric, centered on the lamp, and of increasing diameters. Each absorbing a fraction of the radiation, these cylinders have a large dissipation surface in a small volume.
Selon une sixième caractéristique principale de l'invention , la lampe et le radiateur convertisseur sont surmontés d'une ou plusieurs grilles 17 .According to a sixth main characteristic of the invention, the lamp and the converter radiator are surmounted by one or more grids 17.
Les grilles les plus proches de la lampe ont pour fonction d'intercepter et de convertir en chaleur partie du flux lumineux, elles sont réalisées en feuillard d'aluminium ou d'acier bruni. La dernière grille sera réalisée en matière plastique résistante à la chaleur et non-conductrice de la chaleur, et de couleur claire afin de ne pas absorber le rayonnement résiduel . Cette dernière grille a un rôle de protection contre les risques de brûlure et elle supporte et recueille sans la brûler la montgolfière repliée.The grilles closest to the lamp have the function of intercepting and converting part of the light flux into heat, they are made of aluminum or burnished steel strip. The last grid will be made of heat-resistant and heat-conductive plastic, and of a light color so as not to absorb the residual radiation. This last grid has a protective role against the risk of burns and it supports and collects without burning the folded hot air balloon.
Une ou plusieurs grilles métalliques brunies horizontales sous la lampe convertissent une partie de flux et font écran à la chaleur rayonnée vers la base de la lampe.One or more horizontal burnished metallic grids under the lamp convert part of the flux and shield the radiated heat towards the base of the lamp.
Selon une caractéristique principale de l'invention, le vol de la montgolfière est régulé.According to a main characteristic of the invention, the flight of the hot air balloon is regulated.
La montgolfière ne s'envole que si sa portance est positive, et le reste suffisamment longtemps. Ainsi, si la montgolfière repose librement sur la lampe, elle restera en équilibre plus ou moins stable juste à l'aplomb de la lampe, sans monter.The hot air balloon only flies if its lift is positive, and remains so long enough. Thus, if the balloon rests freely on the lamp, it will remain in more or less stable equilibrium just below the lamp, without going up.
En effet, cet équilibre est atteint à la température critique, et la température baisse dés que la montgolfière s'éloigne de la source de chaleur, quand elle quitte la lampe.Indeed, this equilibrium is reached at the critical temperature, and the temperature drops as soon as the hot air balloon moves away from the heat source, when it leaves the lamp.
Aussi, pour assurer l'envol et la sustentation de la montgolfière, celle ci doit quitter la base avec une température moyenne supérieure à la température d'équilibre, il faut donc en quelque sorte que la montgolfière soit maintenue sur la base.Also, to ensure the flight and the lift of the hot air balloon, it must leave the base with an average temperature higher than the equilibrium temperature, so it is necessary in a way that the hot air balloon is maintained on the base.
Pour ce faire il est réparti au moins trois aimants 25 à la périphérie du col de l'embouchure de la base et de la montgolfière. L'embouchure de la montgolfière est de préférence un anneau métallique très léger 26, par exemple un fil d'acier trempé de faible diamètre, de type corde à piano.To do this, at least three magnets 25 are distributed on the periphery of the neck of the mouth of the base and of the hot air balloon. The mouth of the balloon is preferably a very light metal ring 26, for example a hardened steel wire of small diameter, of the piano string type.
Les aimants assurent la rétention de la montgolfière, qui décolle alors avec une force ascensionnelle équivalente à la force de rétention.The magnets ensure the retention of the hot air balloon, which then takes off with an ascending force equivalent to the retention force.
Le vol de la montgolfière dure le temps que l'air confiné reste plus chaud que la température critique.The flight of the balloon lasts as long as the confined air remains warmer than the critical temperature.
Selon une caractéristique principale de l'invention, la base est sécurisée par un procédé thermo-magnétique :According to a main characteristic of the invention, the base is secured by a thermomagnetic process:
Les aimants perdent leur attraction à partir d'une température critique nommée point de curie. Situés à la périphérie de l'embouchure, les aimants sont exposés à la température de l'air 22, et protégés par les radiateurs du flux thermique rayonné direct.Magnets lose their attraction from a critical temperature called the curie point. Located at the periphery of the mouth, the magnets are exposed to the temperature of the air 22, and protected by the radiators from the direct radiated heat flow.
Ainsi, réchauffement excessif de la base et de l'air dans la montgolfière surchauffe les aimants et favorise la libération de celle ci, ce qui permet alors de refroidir la base, et les aimants 25.Thus, excessive heating of the base and of the air in the hot air balloon overheats the magnets and promotes the release of the latter, which then makes it possible to cool the base, and the magnets 25.
Selon une caractéristique principale de l'invention, la base est protégée par un thermostat.According to a main characteristic of the invention, the base is protected by a thermostat.
Dans le flux d'air périphérique 22, isolé du rayonnement thermique direct, un thermostat interrompt le courant d'alimentation de la lampe dés dépassement d'une température critique.In the peripheral air flow 22, isolated from direct thermal radiation, a thermostat interrupts the lamp supply current as soon as a critical temperature is exceeded.
La température 22 ne s'élevant qu'avec celle de l'air confiné, elle constitue le meilleur témoin d'une élévation anormale liée par exemple à un confinement excessif et accidentel de la base.The temperature 22 rising only with that of the confined air, it constitutes the best witness of an abnormal rise linked for example to an excessive and accidental confinement of the base.
Selon l'invention , la montgolfière est réalisée en tissu ou en film de matière plastique, résistant à la chaleur. Le film est de préférence très fin , pour la recherche de légèreté, de l'ordre de quelques microns. Le film peut comporter des motifs décoratifs, peints ou imprimés.According to the invention, the hot air balloon is made of fabric or plastic film, heat resistant. The film is preferably very thin, for the search for lightness, of the order of a few microns. The film may include decorative, painted or printed patterns.
Enfin, trois versions de l'invention sont adaptées l'uneFinally, three versions of the invention are adapted, one
