Abstract

The surface (4) to be made luminous, such as a false ceiling or wall of light-diffusion material, is mounted below or in front of a parallel hidden surface (1) supporting regularly spaced (XC) light sources (2) utilising induction-type lamps. Though such courses themselves provide diffused light, the necessarily restricted separation from the visible surface (4) produces variable luminance. To obtain more uniform diffusion, round or square diffusing glass or polycarbonate plates (3) are interposed between each source and the visible surface, at a distance, in each installation, adjustable for optimum effect.

Description

La présente invention concerne un dispositif d'éclairage, destiné à être mis en application pour rendre lumineux, des surfaces constituées d'un matériau diffusant.The present invention relates to a lighting device, intended to be applied to make light, surfaces made of a diffusing material.

Dans le bâtiment, la réalisation de grandes surfaces lumineuses diffusantes, que ce soit plafonds, ou parois, nécessite traditionnellement la mise en place d'un certain nombre de sources lumineuses placées à l'amère du matériau constitutif de la surface vue
Se pose alors le problème de l'iniformité de luminance de cotte surface, an. que des problèmes thermiques et d'accès aux sources pour leur entretien.
In the building, the realization of large diffusing luminous surfaces, that it is ceilings, or walls, traditionally requires the installation of a certain number of light sources placed with the bitter of the material constituting the seen surface
This raises the problem of the uniformity of luminance of this surface, an. that thermal problems and access to sources for their maintenance.

Si cet accès n'est pas possible par la face non vue, il faut prévoir lorsque ces parois sont réalisées en verre, ou en maténaux synthétiques, des systèmes d'ouvrants toujours délicats et coûteux
Lorsque le maténau est constitué d'un textile ou d'un maténau synthétique souple et tendu, l'accès ne peut se faire que par la face non vue Ce qui suppose un volume permettant à l'homme d'intervenir dans de bonnes conditions.
If this access is not possible by the side not seen, it is necessary to envisage when these walls are carried out out of glass, or synthetic materials, systems of opening always delicate and expensive
When the material is made of a textile or a flexible and stretched synthetic material, access can only be made from the side that is not seen, which implies a volume allowing man to intervene in good conditions.

Dans tous les cas de figure, les caracténstis des sources incandescentes.In all cases, the characteristics of incandescent sources.

fluorescentes, ou à décharge, font que ces systèmes d'éclairage sont d'entretien difficile, techniquement et/ou économiquement non viables
Le dispositif objet de l'invention, est d'utiliser les caracténstiques d'une source de lumière déjà diffuse en elle même, d'une durée de vie exceptionnelle, et d'un allumage instantané La lampe à induction
La durée de vie de cette source est de 60000h, et permet compte tenu de l'exploitation normale d'un bâtiment, d'éviter toute maintenance pendant des décennies
Son rapport lumen/watt en fait une source de lumière économiquement et thermiquement viable dans un bâtiment.
fluorescent, or discharge, make these lighting systems difficult to maintain, technically and / or economically unsustainable
The device which is the subject of the invention is to use the characteristics of a light source already diffused in itself, of an exceptional lifetime, and of instantaneous ignition. The induction lamp
The lifespan of this source is 60000h, and allows taking into account the normal operation of a building, to avoid any maintenance for decades
Its lumen / watt ratio makes it an economically and thermally viable light source in a building.

Son allumage, réellement instantané, autonse sa mlse en place sur un système de pilotage électrique ou électronique tel qu'il est possible de créer des effets d'animations de lumière sur l'ensemble de la surface
Un accessoire permettant de régler l'uniformité de la face visible doit être placé devant la source, lorse la distance D devient insuffisante.Cet accessoire, lui même en maténau diffusant est installé à une distance adéquate de la source (d) ll a pour objet de filtrer le point de haute luminance que constitue forcément une source nue, et devient par là même une source secdae, d'épaisseur (e), et de dimensions (F). (Voir Fig. 1)
Cette source secondaire, elle même placée à une distance adéquate (D) du matériau de parement, étale de nouveau la lumière et permet d'obtenir une certaine surface (S), de luminance uniforme à l'oeil. (Voir Fig. 1).
Its ignition, really instantaneous, does not require its installation on an electric or electronic control system such that it is possible to create effects of light animations on the whole surface
An accessory allowing to regulate the uniformity of the visible face must be placed in front of the source, when the distance D becomes insufficient. This accessory, itself in diffusing material is installed at an adequate distance from the source (d) It has for object to filter the point of high luminance that necessarily constitutes a naked source, and thereby becomes a secondary source, of thickness (e), and of dimensions (F). (See Fig. 1)
This secondary source, itself placed at an adequate distance (D) from the facing material, spreads the light again and makes it possible to obtain a certain surface (S), of uniform luminance to the eye. (See Fig. 1).

La juxtaposition sous forme d'un maillage régulier, d'interdistance X, des éléments ci dessus, montés sur un support (1), permet d'obtenir des surfaces lumineuses un@formes de très grandes dimensions. A titre d'exemple, non limitatif, l'accessoire de diffusion peut être réalisé d'une plaque carrée ou ronde en Polycarbonate, en verre diffusant ou séngraphié
L'ensemble des dimensions, D, d, X, S, e, F, sont déterminées au cas pg cas, selon les volumes architecturaux.
The juxtaposition in the form of a regular mesh, of interdistance X, of the above elements, mounted on a support (1), makes it possible to obtain luminous surfaces a @ shapes of very large dimensions. By way of example, without limitation, the diffusion accessory can be made of a square or round plate in Polycarbonate, in diffusing or sengraphed glass.
The set of dimensions, D, d, X, S, e, F, are determined on a case-by-case basis, according to the architectural volumes.

Le dispositif selon l'invention est particulièrement destiné à la rsation de plafonds ou parois lumineuses, à l'inténeur ou à l'extérieur des bâtiments The device according to the invention is particularly intended for rsation of ceilings or light walls, inside or outside buildings
