La invención se entenderá bien con la lectura de la descripción siguiente de un ejemplo de realización, con referencia a la única figura que representa una vista esquemática en corte de un dispositivo de alumbrado según la invención.The invention will be well understood with the reading of the following description of an embodiment example, with reference to the only figure that represents a schematic view in cutting of a lighting device according to the invention.

Tal como muestra esta única figura, el dispositivo de alumbrado, objeto de la invención, está constituido por un recipiente 1 con paredes al menos parcialmente transparentes o translúcidas para permitir la visualización del contenido del recipiente. Este recipiente 1 puede realizarse en un gran número de formas. En el ejemplo representado, este recipiente 1 está constituido por una copa. El material que constituye este recipiente puede ser vidrio, un material plástico o cualquier otro material adecuado para soportar un aumento de temperatura. Este recipiente 1 está parcialmente lleno de un líquido 4 no combustible. Este líquido 4 no combustible está, en el ejemplo representado, constituido por agua. Sin embargo, puede utilizarse cualquier otro líquido generalmente transparente o translúcido, coloreado o no. Este líquido 4 no combustible se mantiene en el interior del recipiente 1 por un combustible 2 termofusible que forma un tapón. Este combustible 2 termofusible puede estar constituido por un gel vertido en caliente sobre la superficie del líquido 4 para adherirse, tras su enfriamiento, a las paredes del recipiente 1. Por tanto, este combustible 2 será generalmente un gel elastómero hidrófobo a base de al menos aceite de parafina hidrogenada y productos de copolímeros. Este tipo de geles es bien conocido por los expertos en esta técnica y se comercializa especialmente con la denominación de CANDEL'GEL por la compañía CANDELIS SARL. Obviamente, la densidad del combustible 2 es inferior a la densidad del líquido 4. Este combustible 2 puede contener además al menos una sustancia odorífera y/o un colorante para acentuar el contraste entre el combustible 2 y el líquido 4 no combustible. Finalmente, el recipiente 1 puede contener un sólido 5 para reducir la cantidad de líquido 4 que debe introducirse en el recipiente 1. Este sólido 5 estará generalmente constituido por un elemento decorativo. Este sólido 5 está preferentemente pegado a las paredes del recipiente 1 de manera que se mantenga una disposición precisa de este sólido 5 en el interior del líquido 4.As this single figure shows, the lighting device, object of the invention, is constituted by a container 1 with at least partially transparent walls or translucent to allow the display of the content of the container. This container 1 can be made in a large number of shapes. In the example shown, this container 1 is constituted by a glass. The material that constitutes this container it can be glass, a plastic material or any other material suitable to withstand a temperature rise. This vessel 1 It is partially filled with a non-combustible liquid 4. This liquid 4 non-combustible is, in the example shown, constituted by Water. However, any other liquid can be used generally transparent or translucent, colored or not. This 4 non-combustible liquid is kept inside the container 1 for a hot melt fuel 2 that forms a plug. This hot melt fuel 2 may consist of a gel hot pouring onto liquid surface 4 to adhere, after cooling, to the walls of container 1. Therefore, this fuel 2 will generally be an elastomeric gel. hydrophobic based on at least hydrogenated paraffin oil and copolymer products. This type of gels is well known for experts in this technique and is marketed especially with the name of CANDEL'GEL by the company CANDELIS SARL. Obviously, the density of the fuel 2 is lower than the density of liquid 4. This fuel 2 may also contain at least an odoriferous substance and / or a dye to accentuate the contrast between fuel 2 and non-combustible liquid 4. Finally the container 1 may contain a solid 5 to reduce the amount of liquid 4 to be introduced into container 1. This solid 5 It will generally consist of a decorative element. This solid 5 is preferably glued to the walls of the container 1 so that a precise arrangement of this solid is maintained 5 inside the liquid 4.

Durante la fabricación de un dispositivo de alumbrado de este tipo, se procede de la siguiente manera. Se llena el recipiente 1 con el líquido 4. En el interior del volumen de este líquido 4, se introduce eventualmente un sólido 5 inmovilizado o no a las paredes del recipiente 1. Se calienta un combustible 2 termofusible a una temperatura superior a su temperatura de fusión y luego se deja enfriar durante un tiempo antes de verterlo sobre la superficie del líquido 4. A modo de ejemplo, se calienta el combustible a una temperatura de fusión del orden de 120ºC, luego se enfría a una temperatura de 80ºC. Esta etapa de enfriamiento permite evitar la formación de burbujas del combustible 2 en la superficie del líquido 4. Este combustible 2 es un gel vertido en caliente sobre la superficie del líquido 4, preferentemente en forma de al menos dos capas sucesivas. El vertido de la segunda capa sólo se realiza tras el enfriamiento de la primera capa. Antes del vertido de la segunda capa, la mecha 3, generalmente equipada en su extremo opuesto a su extremo libre 3A susceptible de encenderse, con una pletina, se dispone por medio de esta pletina en la superficie de la primera capa. Se vierte la segunda capa de combustible de manera que la mecha 3 queda integrada en la segunda capa. El combustible utilizado, que forma así un tapón del recipiente, se introduce en tal cantidad que un extremo de la mecha 3 sobresale del tapón y puede así encenderse para permitir el alumbrado del conjunto. Un dispositivo de este tipo funciona por tanto a modo de vela mediante el simple encendido del extremo libre de la mecha.During the manufacture of a device lighting of this type, proceed as follows. It fills up the container 1 with the liquid 4. Inside the volume of this liquid 4, an immobilized solid 5 is eventually introduced or not to the walls of the container 1. A fuel 2 is heated hot melt at a temperature higher than its melting temperature and then let it cool for a while before pouring it over the surface of the liquid 4. As an example, the fuel at a melting temperature of the order of 120 ° C, then it is cooled to a temperature of 80 ° C. This stage of cooling allows to avoid the formation of bubbles of the fuel 2 in the surface of liquid 4. This fuel 2 is a gel poured into heat on the surface of liquid 4, preferably in shape of at least two successive layers. The pouring of the second layer only It is done after cooling the first layer. Before the Poured from the second layer, wick 3, usually equipped in its opposite end to its free end 3A capable of igniting, with a plate, it is arranged by means of this plate in the surface of the first layer. The second layer of fuel so that the wick 3 is integrated into the second cap. The fuel used, which thus forms a plug of the container, is introduced in such quantity that one end of the wick 3 protrudes from the cap and can thus ignite to allow set lighting. Such a device works by both as a candle by simply lighting the free end of the wick.
