[0001] The present invention relates to a door or window with a lighting device. The invention
also relates to a lighting section capable of being used with or inserted in said
door or window.
[0002] The lighting of particular environments can become problematical on account of the
fact that, either for aesthetic reasons or lack of an appropriate space, it is not
possible to make use of the traditional light sources. This is the case, for example,
of rooms of particular artistic or architectural interest and of halls and rooms in
museums. On the other hand, there may also be needs deriving from pure design considerations
or from the arrangement of the interiors that make it unfeasible the installation
of light sources in a conventional manner.
[0003] In many cases, moreover, even the natural lighting provided by an adequate number
of windows can be utilized only to a very limited extent, because the windows may
be screened to a more or less substantial extent by, for example, the employment of
special glasses or reflection curtains, due to a wide variety of reasons, including-for
example - reasons of security or privacy or to prevent damage to precious materials
or objects that may prove sensitive to direct exposure to sunlight.
[0004] The object of the present invention is to provide a door or window, capable of satisfying
the need discussed above.
[0005] Another purpose of the present invention is to provide a lighting section capable
of being used with or incorporated in a door or window in order to render it suitable
for illuminating environments in which it is not possible to install conventional
light sources.
[0006] These aims are attained by means of the door or window and the associated lighting
section in accordance with the present invention, the feature of which are set out,
respectively, in claim 1 and claim 6. Further important characteristics of the invention
are set out in the dependent claims.
[0007] The characteristics and the advantages of the door or window and the associated lighting
section in accordance with the present invention will be apparent from the following
description of embodiments thereof, which is given purely by way of example and is
not to be considered limitative in any way, said description making reference to the
attached drawings, of which:
- Figure 1 shows a partial cross section of a first embodiment of the invention;
- Figure 2 shows a partial cross section of a second embodiment of the invention.
[0008] Referring to Figure 1, the reference number 1 has been used to schematically indicate
a portion of a window frame, while 2 indicates a glass panel supported in a conventional
manner within said frame. On one face of the glass panel there extends a layer 3 of
material capable of reflecting at least a part of the light radiation arriving from
outside, schematically indicated by the arrow R, for example, a sunscreen tissue.
The edges of the glass panel 2 are engaged in a continuous groove 4 provided in an
intermediate position along the inner side 1a of the frame 1. The latter, of course,
may be either of the type that can move, slide or swivel with respect to a window
opening within which it is mounted or may be installed in a fixed position in that
same opening.
[0009] The continuous groove 4 divides the inner side 1a of the frame 1 into two parts and
on the part that is situated on the same side as the layer 3 there is provided a continuous
and substantially C-shaped section 5 of which the open side is turned towards the
centre of the window. The section may be made of metal, plastic material, wood or
any other substantially rigid material. Inside the section 5 there is accommodated
one or more light sources 6, advantageously of the tubular or fluorescent type, aligned
within the seating formed by the section 5, or made up of a plurality of punctiform
light sources placed at such a distance from each other as to give rise to a substantially
continuous illumination. The section 5 may extend for the entire length of the inside
faces of the frame 1 or merely along some parts thereof, for example, only along the
longitudinal sides and any longitudinal crosspieces.
[0010] Advantageously, the section 5 may be provided with feet or small ribs 5a that extend
from its base and delimit - between the base and the inner side 1a of the frame 1
- a space 7 within which there may pass the cables 9 providing the electricity supply.
[0011] A finishing frame 8 is provided on the outside of the section 5 on the side opposite
the glass panel 2 in order to hide the section from view. The frame 8 may be fixed
in any known manner to the corresponding side face of the frame 1.
[0012] A substantial part of the light emitted by the light source 6 will be reflected into
the interior of the environment by the reflecting layer provided on the glass panel
2, while only a small fraction, not greater than 30%, will be transmitted to the outside.
[0013] The solution described above makes it possible to apply the invention to existing
windows. The embodiment of the invention shown in Figure 2, on the other hand, makes
it possible to produce windows that are already predisposed for containing a light
source. In fact, Figure 2 shows a section through a metal section, made of aluminium
for example, that permits the production by means of known techniques of a metal frame
10 for a window to be fixed - typically by means of hinges - to a counterframe 11
integral to the wall structure 20. On the inside face 10a of the frame 10 there are
provided two continuous grooved seatings 12 and 13. The first seating 12 is intended
to engage in a conventional manner with the perimetral edges of a glass panel 14,
while the second seating 13 accommodates a light source 15 of the previously specified
type. Advantageously, the light source may be anchored by means of elastic counteracting
members to the walls of the seating 13, which may be configured in such a way as to
enable it to accommodate also at least one power supply unit 17 for the light source
or the light sources contained therein. On the inner face 10a of the frame 10 between
the two seatings 12 and 13 there is also provided a continuous groove 18 intended
to accommodate the edges of a movable reflecting curtain 19. As an alternative, of
course, the reflecting element in this case may once again be applied directly to
the glass panel or use may be made of reflecting glasses of equivalent functionality.
[0014] The shape of the section used to obtain the frame 10 may vary with respect to the
one here illustrated in accordance with the specific technical and aesthetic requirements.
