Selon une forme de réalisation préférée de l'invention, le According to a preferred embodiment of the invention, the
liquide non combustible est un liquide, de préférence aqueux, transparent ou translucide, coloré ou non. non-combustible liquid is a liquid, preferably aqueous, transparent or translucent, colored or not.
L'invention sera bien comprise à la lecture de la The invention will be well understood on reading the
description suivante d'un exemple de réalisation, en20 référence à la figure unique qui représente une vue schématique en coupe d'un dispositif d'éclairage conforme à following description of an exemplary embodiment, with reference to the single figure which represents a schematic sectional view of a lighting device according to
l'invention. Comme le montre cette figure unique, le dispositif d'éclairage, objet de l'invention, est constitué d'un récipient 1 à parois au moins partiellement transparentes ou translucides pour permettre la visualisation du contenu du récipient. Ce récipient 1 peut affecter un grand nombre de formes. Dans l'exemple représenté, ce récipient 1 est30 constitué par un verre à pied. La matière constitutive de ce récipient peut être du verre, une matière plastique ou toute autre matière apte à supporter une élévation de température. Ce récipient 1 est partiellement rempli d'un liquide 4 non combustible. Ce liquide 4 non combustible35 est, dans l'exemple représenté, constitué par de l'eau. Toutefois, tout autre liquide généralement transparent ou translucide, coloré ou non, aurait pu être utilisé. Ce liquide 4 non combustible est maintenu à l'intérieur du 3 récipient 1 par un combustible 2 thermofusible formant bouchon. Ce combustible 2 thermofusible peut être constitué d'un gel coulé à chaud à la surface du liquide 4 pour adhérer, après refroidissement, aux parois du récipient 1.5 Ce combustible 2 sera donc généralement un gel élastomère hydrophobe à base au moins d'huile de paraffine hydrogénée et de produits copolymères. Ce type de gel est bien connu à ceux versés dans cet art et est notamment commercialisé sous la dénomination CANDEL'GEL par la Société CANDELIS10 SARL. Bien évidemment, la densité du combustible 2 est inférieure à la densité du liquide 4. Ce combustible 2 peut encore contenir au moins une substance odoriférante et/ou un colorant pour accentuer le contraste entre combustible 2 et liquide 4 non combustible. Le récipient 1 peut enfin15 contenir un solide 5 pour réduire la quantité de liquide 4 à introduire dans le récipient 1. Ce solide 5 sera généralement constitué par un élément décoratif. Ce solide est de préférence collé aux parois du récipient 1 de manière à maintenir un positionnement précis de ce solide 5 invention. As shown in this single figure, the lighting device, object of the invention, consists of a container 1 with walls at least partially transparent or translucent to allow viewing of the contents of the container. This container 1 can take on a large number of shapes. In the example shown, this container 1 is constituted by a stemmed glass. The constituent material of this container may be glass, a plastic material or any other material capable of withstanding a rise in temperature. This container 1 is partially filled with a non-combustible liquid 4. This non-combustible liquid 4 is, in the example shown, constituted by water. However, any other generally transparent or translucent liquid, colored or not, could have been used. This non-combustible liquid 4 is held inside the container 3 by a hot-melt fuel 2 forming a plug. This hot-melt fuel 2 may consist of a gel poured hot on the surface of the liquid 4 to adhere, after cooling, to the walls of the container 1.5 This fuel 2 will therefore generally be a hydrophobic elastomeric gel based at least on paraffin oil. hydrogenated and copolymer products. This type of gel is well known to those skilled in this art and is marketed in particular under the name CANDEL'GEL by the company CANDELIS10 SARL. Obviously, the density of the fuel 2 is less than the density of the liquid 4. This fuel 2 can also contain at least one odoriferous substance and / or a dye to accentuate the contrast between fuel 2 and non-combustible liquid 4. The receptacle 1 can finally contain a solid 5 to reduce the quantity of liquid 4 to be introduced into the receptacle 1. This solid 5 will generally consist of a decorative element. This solid is preferably glued to the walls of the container 1 so as to maintain a precise positioning of this solid 5
à l'intérieur du liquide 4.inside the liquid 4.
Lors de la fabrication d'un tel dispositif d'éclairage, on procède de la manière suivante. Le récipient 1 est rempli du liquide 4. A l'intérieur du volume de ce liquide 4, il25 est éventuellement introduit un solide 5 immobilisé ou non aux parois du récipient 1. Un combustible 2 thermofusible During the manufacture of such a lighting device, the procedure is as follows. The receptacle 1 is filled with the liquid 4. Inside the volume of this liquid 4, there is optionally introduced a solid 5 which may or may not be immobilized on the walls of the receptacle 1. A hot-melt fuel 2
est chauffé à une température supérieure à sa température de fusion puis laissé à refroidir quelques instants avant coulage à la surface du liquide 4. A titre d'exemple, le30 combustible est chauffé à une température de fusion de l'ordre de 120 C puis refroidi à une température de 80 C. is heated to a temperature above its melting point and then allowed to cool for a few moments before pouring onto the surface of the liquid 4. For example, the fuel is heated to a melting temperature of the order of 120 C and then cooled. at a temperature of 80 C.
Cette étape de refroidissement permet d'éviter un bullage du combustible 2 à la surface du liquide 4. Ce combustible 2 est un gel coulé à chaud à la surface du liquide 4, de préférence sous forme d'au moins deux couches successives. La coulée de la seconde couche ne se fait qu'après refroidissement de la première couche. Avant coulée de la seconde couche, la mèche 3, généralement équipée, à son 4 extrémité opposée à son extrémité libre 3A susceptible d'être enflammée, d'une platine, est disposée, par l'intermédiaire de cette platine, à la surface de la première couche. La seconde couche de combustible est5 coulée de sorte que la mèche 3 est intégrée dans la seconde couche. Le combustible utilisé formant ainsi bouchon du récipient est introduit dans une quantité telle qu'une extrémité de la mèche 3 fait saillie du bouchon et peut être ainsi enflammée pour permettre l'éclairage de l'ensemble. Un tel dispositif fonctionne alors à la manière d'une bougie par simple inflammation de l'extrémité libre This cooling step makes it possible to prevent bubbling of the fuel 2 at the surface of the liquid 4. This fuel 2 is a gel cast hot on the surface of the liquid 4, preferably in the form of at least two successive layers. The casting of the second layer takes place only after cooling of the first layer. Before casting the second layer, the wick 3, generally equipped, at its 4 end opposite its free end 3A capable of being ignited, with a plate, is placed, via this plate, on the surface of the first layer. The second layer of fuel is cast so that the wick 3 is integrated into the second layer. The fuel used thus forming the plug of the container is introduced in an amount such that one end of the wick 3 protrudes from the plug and can thus be ignited to allow lighting of the assembly. Such a device then operates like a candle by simple ignition of the free end.
