FR2877736A1 - Light passing device for e.g. stall wall, has optical fiber inserted into opaque object made up of opaque material for traversing them on both sides to traverse light, where optical fiber is transversed perpendicularly to object - Google Patents

Abstract

The device has an optical fiber inserted into an opaque object made up of opaque material such as gypsum plaster, concrete, mortar, wood and insulating composite for traversing them on both sides to traverse the light. The optical fiber is transversed perpendicularly to the object. The object is a panel, stall wall, wall of car parking, facing of wall backing, wall of facade and floor of a building.

Description

The present invention relates to a device allowing the light to

  cross a normally opaque wall or partition, ranging in thickness from 10mm to infinity.

  The size of the panels can be infinite too, since they can be managed by the weight and assemble them to each other in width and height.

  The material is indifferent; it can be wood, gypsum board, plaster and especially concrete. * (see page indexed) For thin layers, it will preferably be made of high performance concrete; Ductal type, BCV or Ceracem.

  This wall or partition is crossed on either side of optical fiber sheathed or unsheathed of all possible diameters.

  The density of optical fibers will depend on the desired effect and the desired transparency and physical strength of the panels produced.

  The product is interactive in natural or artificial light.

  It can be used in floor (structural), load-bearing walls, partition, decorative and artistic element, because either the optical fibers are through perpendicular to the panel, or can be axially offset between one side and the other of the visible walls. (see cuts, sketches 1,2 and 3) On the deposited photo, the optical fibers are perpendicular to the visible faces. Use: Partition walls where there should be no openings, but where the light can pass.

  For security: parking or other walls where can be read all presences and movements.

  In floor idem, a transparency that will detect any movement, any silhouette suspicious or not, can be detected.

  In phenomenal potential architecture of applications for the game with light.

  Indexed page The idea is to make an opaque material transparent, or to let light in a panel or opaque object.

  Example: Concrete that is completely opaque can become partially transparent without losing its structural qualities, retaining all its qualities.

Claims (5)

claims   1) This device allows an opaque material to let the light through. Because the optical fiber inserted into the material, plaster, concrete, mortar, wood panels, insulating composites, etc. crossing these materials on both sides makes crossing the light. (See plate 1/3) 2) Device by claim 1 therefore allows where any mass, human body, object, etc. is interposed between the light source and the wall treated in light pass to see the silhouette of the less illuminated side. (plate 2/3) 3) The device according to claim 2 allows the creation of structural walls and floors that are non-load bearing elements (partition walls or filler faces) or carriers (walls of facades and floors of a building).   4) This device according to claim 3 allows to manufacture in the factory, workshop or on site of traditional concrete or high performance concrete made by pouring into formwork pre equipped with fiber optics.   5) This device including claims 1, 2 and 3 is not limiting in the forms; it can be applied for flat shapes, but also in any other geometry.
