Definitions

  • the invention relates to a transparent panel intended to be mounted, in particular, in a building window bay and making it possible to reorient the incident natural light rays so as to homogenize the brightness at inside the building.
  • the invention will be described more particularly for a building window in which the transparent panel will be mounted so as to redirect the incident natural light rays towards the ceiling of the room in said building, but the invention is not limited to this type of application, any type of opening made in a building and able to receive a transparent panel also enters in the context of the invention.
  • a technique known to improve the level of natural light in inside a room is to deflect the natural light rays incident by through glazing so that at least some of it is reflected towards the ceiling of the room which in turn reflects them inside the room.
  • we increase the level of natural light throughout the room by modifying the distribution of light rays, in particular in the areas of the that are far from the window.
  • the means used to deflect the shelves luminous incidents through glazing consist either of the use of prisms made of a transparent material which refract the incident light ray either by using metallic surfaces which reflect the light ray incident.
  • glazing one face of which is molded so as to form a series of prisms.
  • such glazing with prismatic surface do not allow to deflect the light rays by an angle greater than 45 ° and it turns out that a deviation of an angle greater than 45 ° from solar rays are often necessary so that they can be directed towards the ceiling of the room.
  • such glazing with a prismatic surface offers, as window, a vision through said glazing which is deformed and the surface of the glazing which presents the series of prisms, is difficult to clean.
  • the present invention aims to provide a panel intended to be mounted, in particular, in a window bay of a building making it possible to deflect incident light rays at an angle greater than 45 ° so as to redirect the rays towards the ceiling of the room and thus improve the level of brightness at inside the room, offering a vision through it which is not distorted and can be cleaned without difficulty.
  • the solution consists in using a flat transparent plastic panel having a plurality of parallel laser cuts and spaced apart from each other by a regular pitch, these cuts being made perpendicular to the panel so as to divide the panel into parallelepipeds on at least part of its thickness.
  • the cutouts are protected from dust with a thin transparent sheet attached to said panel.
  • the object of the invention is to provide a panel intended to be mounted, in particular, in a window bay of a building which obviates disadvantages previously mentioned and can be implemented quickly and easily without stage of finishing the surface condition of the cuts.
  • the invention thus provides a transparent panel intended to be mounted, in particular, in a window bay of a building and making it possible to reorient incident natural light rays so as to homogenize the brightness at inside the room, the panel is such that it includes at least one sheet of glass having, on at least part of its thickness, grooves arranged horizontally and parallel to each other.
  • the grooves are laser cuts of the sheet of glass.
  • the grooves present on the surface of the glass sheet are produced by the creation of cracks whose depth is controlled. Their surface internal is optically smooth and thus allows a total reflection of the rays bright natural incidents.
  • the grooves are substantially perpendicular to the plane of the glass sheet.
  • the grooves are distributed uniformly over the surface of the glass sheet.
  • the glass sheet is part of a laminated panel and the depth of the grooves is equal to the thickness of the sheet of glass.
  • the grooves are made directly on the whole laminate and the depth of the laser cutting of the grooves is advantageously controlled by the presence of the interlayer of the laminated panel, the rest of the glass sheet being held in place by the same interlayer.
  • the ratio of the depth of the grooves on the distance between two grooves is between 0.5 and 2 and, from preferably between 1 and 2. In this way, the number of rays is optimized bright natural incidents that are going to be redirected.
  • the transparent panel is part multiple insulating glazing.
  • the surface of the panel presenting the grooves is in contact with the gas plate of the insulating multiple glazing and is thus protected from dust and moisture.
  • such a variant makes it possible to realize multiple insulating glazing combining insulating performance with advantages of glazing improving the brightness of a room.
  • the transparent panel allows, as explained above, to deviate incident light rays at an angle greater than 45 ° so as to redirect the rays towards the ceiling of the room and thus improve the level of brightness natural inside the room.
  • Such a panel also makes it possible to obtain a vision through without distortions.
  • Figure 1 shows a part of a vertical section of a panel 1 according to the invention.
  • the panel 1 consists of a glass sheet 2 on which a series of grooves 3 has been produced by a laser cutting technique such as, for example, by the technique described in European patent EP-B -0 633 867.
  • the grooves 3 have, for example, a depth of 0.8 mm for a total thickness of the glass sheet 2 of 2 mm.
  • the grooves 3 are arranged horizontally with respect to the general plane of the glass sheet 2 and are parallel to each other and spaced from each other by a pitch of 0.5 mm by for example, a depth / step ratio of 1.6.
  • the grooves 3 are perpendicular to the plane general of the glass sheet 2 and are delimited by two internal faces 4 and 5.
  • These internal faces 4 and 5 represent the walls of the crack generated by laser beam and are distant from each other, but sufficiently close so as to remain invisible to the eye.
  • An incident light ray 6 comes into contact with the glass sheet 2 on its face 7, it is deflected by refraction at the level of face 7, then by refraction total at the level of the internal face 4 of the groove 3 and again by refraction at level of the face 8 of the glass sheet 2.
  • Another incident light ray 9 comes into contact with the glass sheet 2 but from a much lower incident angle, it is then deflected only by refraction at the faces 7 and 8 of the glass sheet 2, to as far as it does not meet a groove 3.
  • FIG. 2 shows a part of a vertical section of another type of panel 1 according to the invention.
  • the panel 1 consists of two sheets of glass 10 and 11 joined together by an interlayer 12.
  • This interlayer 12 is, for example, a polyvinyl butyral sheet (PVB).
  • the glass sheet 11 has a series of grooves 3 identical to that of the Figure 1, with the difference that the glass sheet 11 is thinner than the sheet of glass 2, its thickness being identical to the depth of the grooves.
  • the glass sheet 10 has a thickness greater than that of the glass sheet 11 and thus serves as a support for the whole of the panel 1.
  • the glass sheet 10 has a thickness of 4 mm and the glass sheet 11 a thickness of 0.8 mm.
  • FIG. 3 represents a vertical section of a building room on which the panel 1 according to the invention has been mounted as a window.
  • FIG. 4 represents a part of a vertical section of a double insulating glazing in which the panel 1 according to the invention has been inserted.
  • the double insulating glazing consists of transparent panel 1 according to the invention and a glass sheet 15, the panel 1 and the glass sheet 15 being separated from each other by an air knife 16 and joined together at their periphery by means of a profiled frame here not shown in the figure and known to those skilled in the art.
  • the grooves 3 of the panel 1 are in contact with the air gap 16.
  • the invention is not limited to these types of embodiment and must be interpreted in a nonlimiting manner and encompassing any type of transparent panel intended to be mounted, in particular, in a window opening and making it possible to redirect the incident natural light rays so as to homogenize the brightness inside the building, said panel comprising a sheet of glass having, on at least part of its thickness, grooves arranged horizontally and parallel to each other.
