Definitions

  • the present invention relates to a window with built-in lighting means. More particularly, the invention relates to a window which is capable of emitting light of its own independently of the light that is present outside the building in which the window is installed.
  • the external lighting conditions are often not sufficient to adequately light the internal enclosed space.
  • the external lighting conditions are often not sufficient to adequately light the internal enclosed space.
  • Such additional lighting can allow to make the space more pleasant, improving the comfort of its occupiers.
  • the aim of the present invention is to provide a window with built-in lighting means which allows to achieve an effective lighting effect as well as a pleasant aesthetic effect.
  • an object of the present invention is to provide a window with built-in lighting means which can be used as a screen for projecting images chosen by the users.
  • Another object of the present invention is to provide a window with built-in lighting means which can be used equally as a conventional window or as a "lighted" window without having to radically change the structure of the window.
  • Another object of the present invention is to provide a window with built-in lighting means in which the framework of the window is not substantially modified with respect to conventional windows and therefore does not alter the aesthetic impact of the window.
  • Another object of the present invention is to provide a window with built-in lighting means whose opening is similar to that of a conventional window.
  • Another object of the present invention is to provide a window with built-in lighting means which is highly reliable, relatively easy to manufacture and at competitive costs.
  • a window with built-in light comprising at least one glass pane which is accommodated within a movable sash which is suitable to be hinged to a fixed casing, characterized in that it further comprises at least one light source which is meant to be accommodated in said sash or casing and to project light rays toward said at least one glass pane.
  • the window according to the present invention comprises a movable sash 1 which is meant to be hinged to a fixed casing 2 of a conventional type.
  • the movable sash 1 surrounds, at a side that is meant to be hinged to the fixed casing 2, a portion 3 for accommodating at least one light source, as described in detail hereinafter.
  • the movable sash 1 surrounds a case which is suitable to accommodate at least one roller which is adapted to unroll and roll up at least one optical film whose function will be explained in detail hereinafter.
  • the window according to the invention further has an internal frame 5 for retaining at least one glass pane 6 of a conventional type.
  • the window has at least one light source, designated by the reference numeral 7, which is accommodated within the portion 3 and is adapted to send light rays parallel to the surface of the glass pane, so as to produce built-in lighting for the window.
  • the window comprises at least one glass pane 6 and at least one light source 7 which is adapted to project light parallel to the glass pane 6.
  • the case 4 contains at least one roller for unrolling a panel which is meant to be substantially in contact with the glass pane 6, so that the light emitted by the light source 7 is not scattered outside the enclosed space in which the window is applied.
  • the window according to the invention has two glass panes 6 which are arranged parallel to each other so as to form, between them, a gap 8, as normally occurs in a common double-glazing unit.
  • the light source 7 thus projects light into the gap between the two glass panes 6, and conveniently there are two panels (optical films) which are unrolled from two rollers 10 and 11 accommodated in the case 4 arranged in the upper portion of the window.
  • the two panels are constituted by optical films: one film 13 is meant to be arranged adjacent to the outer glass pane 6 and is conveniently constituted by a material which is adapted to fully reflect the light emitted by the light source. Said material thus behaves like a mirror.
  • the second panel 12 unrolled from the roller 10 and meant to be lowered adjacent to the inner pane 6 is made of light-scattering material, so as to scatter the light introduced by the light source 7 in the gap 8 between the two glass panes 6.
  • the two unwinding rollers of the optical films 12 and 13 are shown; one of said optical films, for example the optical film 12 with the corresponding roller 10, is shown in Figure 5.
  • a weighting bar 14 is coupled to the end of the optical film 12 in order to keep said film 12 stretched; said film is lowered into a guide 15 which runs parallel to the guide that accommodates the glass pane 6.
  • the unrolling of the optical film 12 occurs in a guided fashion and the optical film is arranged parallel to the glass pane, inside the gap 8 provided between the two inner and outer glass panes 6.
  • Figure 5 is a detail view of the connection between the optical film 12 and the weighting bar 14.
  • optical deflection means conveniently constituted for example by an optical prism 20 which is shaped so that the light rays emitted by the light source 7 strike the surface of the inner glass pane 6.
  • the effect of this prism is clearly indicated in Figures 3 and 6.
  • the light rays emitted by the light source 7 are carried by adopting suitable conveyance means, provided for example by a parabolic mirror 21 arranged so as to wrap around the light source 7 and thus convey onto the prism 20 also the light rays that would otherwise scatter in the opposite direction with respect to the gap 8 provided between the two glass panes 6.
  • the optical prism 20 is thus constructed so that the rays that pass through the prism are incident to the optical film 12 that is arranged inside the inner glass pane 6.
  • the optical film 12 made of light-scattering material, causes the rays that are incident thereon to be reflected substantially at 90° with respect to the direction of incidence. This entails a diffusion of the light emitted by the light source 7 into the enclosed space, thus meeting one of the objects of the invention.
  • At least one image projection element which is conveniently constituted for example by a strip 22 which is arranged for example parallel to the movable sash of the window and is arranged substantially so as to face the light source 7.
  • the use of the projection strip 22 allows to project chosen images onto the optical film 12, so that said images are visible through the glass plate of the window.
  • FIG 2 is a detailed view of the arrangement of the light source 7, of the projection strip 22 and of the prism 20.
  • the light source is accessed by opening a flap 24 which is provided so as to cover the portion 3 that accommodates the light source 7.
  • the light source 7 is accommodated in a box-like body 25 which also accommodates the projection strip 22, which is inserted in front of the light source 7 by making it slide with an insertion movement at right angles to the surface of the window.
  • the box-like body is provided with feet 26 which run between pairs of guides 27 and 28, thus allowing to insert and extract the box-like body 25 from the corresponding seat provided between the movable sash 1 of the window and the edges of the glass panes 6.
  • the box-like body 5 is internally shaped like a parabolic arc (so as to form said optical conveyance means) and its inner surface is mirror-finished, so as to achieve the effect of reflecting the light rays emitted by the light source 7 toward the projection strip 22 and the prism 20.
  • the electrical components are conveniently accommodated in a container 30 on the outer surface of the box-like body 25, which can be accessed by opening the door 24.
  • Two handles 31 are provided for extracting and inserting the box-like body 25 in its seat.
  • the door 24 is further provided with a handle 35 of its own for opening the door 24 in order to access the box-like body 25.
  • the optical prism 20 delimits the gap region 8 between the two glass panes 6.
  • the prism faces a sheet 36 of transparent material, such as for example Plexiglas;
  • a sheet 37 in which the surface that faces the sheet 36 is of the mirror-finished type.
  • the light source 7 when the light source 7 is switched on the light rays are directed toward the gap 8.
  • the light beam that originates from the light source 7, which is the light beam that lies closest to the outer glass pane 6, is reflected, owing to the presence of the optical prism 20, at the opposite corner of the window, so that the entire surface of the glass pane 6 is affected by the light rays emitted by the light source 7.
  • the optical films 12 and 13 allow, when lowered, to convert the window, screening completely the view outside the window and reflecting completely toward the inside of the enclosed space the light rays emitted by the light source 7.
  • the strip 22 for projecting light/images can be conveniently provided with patterns and various images, which can thus be projected onto the surface of the glass pane 6 inside the enclosed space.
  • the described arrangement of the light source 7 is merely an example, since such light source can be equally arranged in an upper region and in a lower region as well as laterally as shown in the figures.
  • light sources 7 with particular colorings allows to obtain aesthetically pleasant effects, for example with eye-resting tones, this being a particularly important factor for example in the case of working spaces.
  • the above-described window can be advantageously used for example also in glazed buildings in which the outer surface of the building is provided by means of a framework in which glass panes are arranged adjacent to each other, so as to give the outer surface of the building a continuous reflective finish.
  • the window according to the invention fully achieves the intended aim and objects, since it allows to obtain an indoor lighting according to the user's wishes, regardless of the presence of external sunlight.
  • the window thus conceived is not substantially modified with respect to a conventional window, since the space for accommodating the box-like body 25 that houses the light source 7 is minimal and does not substantially affect the aesthetics of the window.
  • the window thus conceived can obviously also be used in the conventional manner, if the user does not wish to switch on the light source and unroll the optical films in contact with the outer and inner glass panes of the window.
  • the window thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.
  • the light source 7 can be accommodated in the fixed casing 2 substantially in the same manner in which it is accommodated in the movable sash 1.
  • the window according to the invention can be used not only as a vertical window but also as a horizontal or otherwise angled window and can be advantageously used as an element for separating internal spaces.
  • the materials used may be any according to requirements and to the state of the art.
