Abstract

The device has a motorized cylinder (2) having outer surface coating that partially absorbs, and is partially transparent to, light from a fixed external source (1), and an inner surface coating of crumpled aluminum paper. Protruding reflective units (3) are tangentially fixed on the outer surface of the cylinder. A visual screen (6) is placed in front of the light source for receiving the light and providing the illusion of bright flames as well as a moving heat halo effect. The protruding reflective units have an extended form, are pointed at both ends, and are oriented in the direction of rotation of the cylinder.

DESCRIPTIONDESCRIPTION

La présente invention concerne un système de simulation visuelle de flammes et de halo de chaleur, utilisant pour seule énergie l'électricité.  The present invention relates to a system for visual simulation of flames and heat halo, using electricity as the sole energy.

Plusieurs systèmes de simulation de flammes ont été utilisés ou illustrés dans le passé, utilisant entre une source lumineuse et un écran utilisateur, a) La réflexion d'une ou plusieurs surfaces réfléchissantes métalliques fixées sur un axe en rotation.  Several flame simulation systems have been used or illustrated in the past, using between a light source and a user screen, a) The reflection of one or more metallic reflecting surfaces fixed on a rotating axis.

b) La réflexion de la surface partiellement ou totalement réfléchissante d'un cylindre - surface par exemple recouverte de papier aluminium froissé ou de petits miroirs non ordonnés.  b) The reflection of the partially or totally reflecting surface of a cylinder - surface for example covered with crumpled aluminum foil or small unordered mirrors.

Les premiers systèmes mentionnés génèrent sur l'écran utilisateur un effet de flamme en mouvement, les seconds un effet halo de chaleur en incandescence..  The first systems mentioned generate a moving flame effect on the user screen, the second an incandescent heat halo effect.

La présente invention décrit un nouveau système de simulation simple mais plus réaliste, alliant effet de flamme (7) et effet halo de chaleur (8).  The present invention describes a new simple but more realistic simulation system, combining flame effect (7) and heat halo effect (8).

Ce système comprend: 1. Une source lumineuse (1) fixe - une ou deux ampoules électriques de 15 ou 25 watts par exemple -.  This system includes: 1. A fixed light source (1) - one or two 15 or 25 watt electric bulbs for example -.

2. Un cylindre (2) avec sur sa surface un revêtement partiellement absorbant 40 partiellement transparent à la lumière _ cylindre en matière plastique de type PVC ou ACRYLIQUE). Cette transparence peut être en partie colorée afin de fournir une illusion chromatique.  2. A cylinder (2) with on its surface a partially absorbent coating 40 partially transparent to light (plastic cylinder of PVC or ACRYLIC type). This transparency can be partly colored in order to provide a chromatic illusion.

Ce cylindre est entraîné en rotation, à vitesse constante, par un moteur de 45 puissance de 5 watts par exemple -, dans le sens du mouvement des aiguilles d'une montre.  This cylinder is driven in rotation, at constant speed, by a 45 watt motor of 5 watts for example -, in the direction of clockwise movement.

3. Une feuille de papier aluminium froissé (4) enroulée sur elle-même à l'intérieur du dit cylindre.  3. A sheet of crumpled aluminum foil (4) rolled up on itself inside said cylinder.

4. Des éléments annexes réfléchissants et protubérants (3) fixés tangentiellement à la surface du cylindre, de forme ovale, allongée en pointe aux deux extrémités, et orientée dans le sens de rotation du cylindre. . 5. Un écran transparent (6) ou partiellement transparent retraduisant pour un oeil extérieur l'illusion de flammes animées. Un séparateur intermédiaire (5), positionné entre l'écran de réception et le cylindre motorisé, canalise le cheminement lumineux, et permet de supprimer tout éclairage ou reflet parasite ou indésirable.  4. Reflective and protruding auxiliary elements (3) fixed tangentially to the surface of the cylinder, of oval shape, elongated at a point at the two ends, and oriented in the direction of rotation of the cylinder. . 5. A transparent (6) or partially transparent screen retranslating for an external eye the illusion of animated flames. An intermediate separator (5), positioned between the reception screen and the motorized cylinder, channels the light path, and makes it possible to suppress any stray or unwanted lighting or reflection.

La réflexion du papier aluminium froissé en mouvement produit un effet visuel de halo de chaleur à travers l'écran de visualisation. Cet effet de halo peut être plus ou moins atténué par la surface des parties non réfléchissantes du 20 cylindre ainsi que par la position du papier aluminium plus ou moins profonde dans le cylindre.  The reflection of the crumpled aluminum foil in motion produces a visual halo of heat through the display screen. This halo effect can be more or less attenuated by the surface of the non-reflecting parts of the cylinder as well as by the position of the aluminum foil more or less deep in the cylinder.

Les éléments annexes réfléchissants provoquent un effet différent, 25 assimilable à la projection de flammes simulées d'autant mieux définies que le contour des surfaces des éléments annexes est franc et leur support plat ou légèrement incurvé, et lisse. La hauteur et largeur des flammes simulées étant directement fonction de la forme d eces elements annexes.  The reflective ancillary elements cause a different effect, which can be assimilated to the projection of simulated flames, all the better defined if the outline of the surfaces of the ancillary elements is clear and their support flat or slightly curved, and smooth. The height and width of the simulated flames being a direct function of the form of these ancillary elements.

C'est la combinaison de ces deux effets distincts mais complémentaires (Flamme + Halo) qui produit un effet nouveau, plus réaliste et saisissant pour l'utilisateur.  It is the combination of these two distinct but complementary effects (Flame + Halo) which produces a new effect, more realistic and striking for the user.
