Description

La présente invention est relative à un panneau lumineux de type nouveau. The present invention relates to a new type light panel.

On connaît déjà des panneaux lumineux composés d'une ou plusieurs plaques de matériaux transparents tel que verre ou plexiglass et comportant une ou plusieurs sources lumineuses dissimulées dans l'encadrement du panneau. Lesdites plaques portent généralement sur une ou les deux faces des indications obtenues par collage, gravure ou dépolissage. La ou les sources lumineuses sont placées à l'arrière de la plaque ou situées en face d'une tranche du panneau. Light panels are already known which are composed of one or more plates of transparent materials such as glass or plexiglass and which include one or more light sources concealed in the frame of the panel. Said plates generally bear on one or both sides of the indications obtained by gluing, etching or frosting. The light source or sources are placed at the rear of the plate or located opposite a section of the panel.

Ces dispositifs comportent de nombreux inconvénients : les dispositifs utilisant la gravure imposent un mode d'inscriptions permanentes ; il en est de même pour les plaques partiellement dépolies. Quant aux inscriptions obtenues par collage, elles nécessitent pour la mise à jour des panneaux l'arrachage de l'inscription, un nettoyage de la colle résiduelle et la pose de nouvelles inscriptions. Les dispositifs existants utilisent des sources lumineuses qui sont soit placées à l'arrière de la plaque à une distance suffisante pour permettre une bonne répartition de la lumière. De ce fait, ces dispositIfs sont encombrants. D'autres panneaux utilisent un éclairage par une tranche. L'éclairage est effectué soit au moyen d'une règlette fluorescente soit par une ou plusieurs ampoules logées dans une enceinte munie d'une fente rectiligne parallèle et en regard de la tranche.Ces systèmes présentent deux inconvénients majeurs : d'une part, la réalisation en est coûteuse et d'autre part, l'encombrement du dispositif d'éclairage nuit à l'esthétique du produit et à sa maniabilité. Enfin, dans les systemes existants, le rendement est faible par suite de la dispersion des rayons. These devices have many drawbacks: devices using engraving impose a permanent registration mode; it is the same for partially frosted plates. As for the inscriptions obtained by gluing, they require for the updating of the panels the removal of the inscription, a cleaning of the residual glue and the laying of new inscriptions. Existing devices use light sources which are either placed at the rear of the plate at a sufficient distance to allow good distribution of the light. Therefore, these devices are bulky. Other panels use edge lighting. The lighting is carried out either by means of a fluorescent strip or by one or more bulbs housed in an enclosure provided with a parallel rectilinear slit and facing the edge. These systems have two major drawbacks: on the one hand, the realization is expensive and secondly, the size of the lighting device affects the aesthetics of the product and its maneuverability. Finally, in existing systems, the efficiency is low due to the dispersion of the rays.

Le dispositif selon l'invention permet de pallier ces inconvénients. The device according to the invention overcomes these drawbacks.

Selon un mode préférentiel de réalisation de l'invention, le panneau est constitué d'une plaque (1) en matériau transparent, ladite plaque comportant sur au moins une tranche (4) plusieurs évidements (2) destinés à recevoir une ou plusieurs sources lumineuses (3), lesdites sources étant constituées par des ampoules à filament basse tension ou par des ampoules de type néon. La plaque (1) comporte sur ses tranches un dispositif de réflexion des rayons lumineux constitué par un matériau reflé
Les évidements (2) sont constitués par des trous cylindro côniques dont les axes sont sensiblement parallèles auX plus grandes faces (5) de la plaque (1).According to a preferred embodiment of the invention, the panel consists of a plate (1) made of transparent material, said plate comprising on at least one edge (4) several recesses (2) intended to receive one or more light sources (3), said sources being constituted by low-voltage filament bulbs or by neon-type bulbs. The plate (1) has on its edges a device for reflecting light rays consisting of a reflected material
The recesses (2) are constituted by cylindrical conical holes whose axes are substantially parallel to the larger faces (5) of the plate (1).

La plaque (1) comporte sur une ou ses deux plus grandes faces (5) une couche destinée à éviter les rayures. Cette couche transparente peut être une peinture, une résine ou un vernis.The plate (1) has on one or its two largest faces (5) a layer intended to prevent scratches. This transparent layer can be a paint, a resin or a varnish.

On peut aussi métalliser la grande face (5) opposée à l'observateur, de manièreà obtenir des effets lumineux supplémentaires.It is also possible to metallize the large face (5) opposite to the observer, so as to obtain additional light effects.

Selon un autre mode de réalisation le revêtement métallique (6) peut comporter des coupures (7) permettant ainsi l'alimentation électrique des sources lumineuses (3). According to another embodiment, the metal coating (6) may include cutouts (7) thus allowing the electrical supply of the light sources (3).

Le revêtement métallique (6) peut avantageusement déborder sur la partie supérieure des grandes faces (5) de la plaque (1). Les fils (8) d'alimentation des sources lumineuses (3) viennent en contact sur le revêtement métallique (6).The metal coating (6) can advantageously extend beyond the upper part of the large faces (5) of the plate (1). The wires (8) supplying the light sources (3) come into contact with the metal covering (6).

Une barrette en matériau isolant (9) venant par pincement assurer un bon contact des fils (8) avec le revêtement métallique (6). La plaque (1) est munie dans une de ses tranches d'une fiche de connexion (10) intégrée destinée à être reliée à l'alimentation électrique du panneau. Les contacts de cette fiche peuvent avantageusement être métallisés dans la masse du panneau.A bar of insulating material (9) coming by pinching ensure good contact of the wires (8) with the metallic coating (6). The plate (1) is provided in one of its sections with an integrated connection plug (10) intended to be connected to the electrical supply of the panel. The contacts of this plug can advantageously be metallized in the mass of the panel.

Selon un autre mode de réalisation, des trous de connexion peuvent être prévus sur la tranche supérieure du panneau pour y rapporter un bloc autonome d'alimentation. Ces fiches permettent en outre l'alimentation d'un deuxième panneau. According to another embodiment, connection holes can be provided on the upper edge of the panel to attach an autonomous power supply. These cards also allow the supply of a second panel.

Selon les divers modes de réalisation de l'invention le dispositif est pourvu d'un encadrement et ou d'un support. According to the various embodiments of the invention, the device is provided with a frame and / or a support.

Le dispositif selon l'invention permet de réduire les coûts de fabrication. L'encombrement du panneau est minimum. The device according to the invention makes it possible to reduce the manufacturing costs. The size of the panel is minimum.

Le rendu lumineux est amélioré. De plus, on peut utiliser les deux faces du panneau soit en éclairage de documents, soit en écriture avec des moyens classiques tels que feutre, craie, crayon gras, soit en impression, effaçable ou non. Le panneau est utilisable sans danger, même par les enfants, l'alimentation électrique étant en basse tension. La simplicité du dispositif permet l'adjonction aisée d'éléments décoratifs.The light rendering is improved. In addition, the two sides of the panel can be used either for document lighting or for writing with conventional means such as felt, chalk, grease pencil, or in printing, erasable or not. The panel can be used without danger, even by children, the power supply being at low voltage. The simplicity of the device allows the easy addition of decorative elements.

Le panneau selon l'invention peut intéresser de manière non limitative les domaines de la formation, de l'information, de la signalisation, de la publicité, du jouet, de la décoration.  The panel according to the invention may be of nonlimiting interest in the fields of training, information, signage, advertising, toys, decoration.
