Abstract
Description
La présente invention concerne des appareils d'éclairage zénithal à lumitre froide, à conducteur optique par fibres de verre, permettant de transfé- rer la lumière solaire à l'intérieur de locaux clos, tels que grands magasins, blocs hôpitaux, immeubles, caves, navires, avions, etc.. sans dégagement calorifique,
Les dispositifs usuels connus sont les fenêtres, les lucarnes et lucarneaux, les hublots, etc.. nais leur efficacité est limitée à lelur proximité, et l'éclairage décroît très rapidement avec la distance ; l'éclairage électrique prend donc le relais, mais il a l'inconvénient de degager une chaleur importante par effet Joule et à consommer de l'énergie, ce qui oblige à une ventiAa- tion ou climatisation des locaux, incompatible avec les économies d'énergie.The present invention relates to overhead lighting fixtures with cold lumber, with optical conductor by glass fibers, making it possible to transfer sunlight into closed spaces, such as department stores, hospital blocks, buildings, cellars, ships, planes, etc. with no heat release,
The usual known devices are windows, dormers and dormers, portholes, etc. However, their effectiveness is limited to their proximity, and the lighting decreases very rapidly with distance; electric lighting therefore takes over, but it has the disadvantage of releasing significant heat by the Joule effect and of consuming energy, which requires ventilation or air conditioning of the premises, incompatible with the savings of energy.
L'éclairage zénithal, selon l'invention, permet d'éviter ces inconvé- nients pendant les heures diurnes. I1 permet en effet l'éclairage total ou partiel par la lumière du jour, des locaux fermés intérieurs, inaccessibles direc tement à celle-ci. Le moyen en est un toron ou câble souple, constitué de fibres de verre transparentes, parallèles et de la longueur du câble ou conducteur. Le principe en est la capacité pour un jet d'eau homogène de conduire a lumière quelqu'en soit la courbe, ledit principe étant appliqué depuis plusieurs annees aux fibres ou fils de verre transparents. The overhead lighting according to the invention makes it possible to avoid these drawbacks during the daytime hours. It indeed allows total or partial lighting by daylight, closed indoor premises, inaccessible directly to it. The means is a flexible strand or cable, made of transparent, parallel glass fibers and the length of the cable or conductor. The principle is the capacity for a homogeneous water jet to lead to light whatever the curve, said principle having been applied for several years to transparent glass fibers or threads.
Selon une première variante, le procédé comporte un ensemble de fibres de verre 1, d'une seule longueur, chacune assemblées en toron souple à l'image d'un cible électrique et se comportant de la même façon sur le plan physi que. According to a first variant, the method comprises a set of glass fibers 1, of a single length, each assembled in flexible strand like an electric target and behaving in the same way on the physical plane as.
Une des extremités du câble est aboutée à un ensemble optique de lentilles convexes 2 concentrant la lumiere extérieure, la deuxième à un autre de lentilles concaves 3 diffusant la lumière intérieurement en 4.One end of the cable is joined to an optical assembly of convex lenses 2 concentrating the exterior light, the second to another of concave lenses 3 diffusing the light internally at 4.
Le dessin annexe est une vue shématique en plan du dispositif. Tel qu' il est représenté, le dispositif comporte un câble 1 constitué d'un certain nombre de fibres continues 2, en verre transparent ;une des extrémités 3, un ensemble optique de lentilles concaves 5, l'autre extrémité 7 comportant un second ensemble de lentilles convexes 8. The accompanying drawing is a schematic plan view of the device. As shown, the device comprises a cable 1 made up of a number of continuous fibers 2, made of transparent glass; one of the ends 3, an optical assembly of concave lenses 5, the other end 7 comprising a second set convex lenses 8.
Quand un bâtiment, quel qu'il soit, doit être équipé du procédé décrit l'ensemble optique 3 se trouve à l'extérieur, et exposé à la lumière zénithale solaire 5, l'autre 7 à l'intérieur du local à éclairer v, la lumière étant conduite par les fibres de verre 2, dont le nombre peut varier selon l'intensité lumineuse requise. When a building, whatever it is, must be equipped with the process described, the optical assembly 3 is outside, and exposed to the zenithal solar light 5, the other 7 inside the room to be lit v , the light being conducted by the glass fibers 2, the number of which can vary according to the required light intensity.
Le dispositif objet de l'invention peut être utilisé dans toue les cas où une économie d'énergie électrique est envisagée, et un éclairage de qualité désiré. The device which is the subject of the invention can be used in all cases where a saving of electrical energy is envisaged, and lighting of desired quality.
Des applications particulièrement intéressantes peuvent être l'éclairage diurne de locaux obscurs et clos, magasins blocs bateaux, avions, grands bâtiments. Particularly interesting applications can be the daytime lighting of dark and closed rooms, stores, ships, planes, large buildings.
