Description of options for carrying out the invention

1 is a side view of the light-emitting panel in accordance with the proposed invention. This panel contains a hard substrate 2, light emitting 4 fabric and accessories, as well as the means intended for installation of the light-emitting fabric 4 on a rigid substrate 2.

Rigid substrate 2 represents, for example, a finishing panel type panel used for the implementation of the walls, namely, how to implement horizontal walls, that is, ceilings, and for the implementation of the vertical walls, that is, partitions of. Thus, here it comes, for example, gypsum panels, such as panels, known as 13, if it is a vertical wall.

Rigid substrate 2 contains two large surfaces and four edges. One of these large surfaces is called the front surface of 6, and another large surface opposite the front surface of 6 is the rear surface of the 8. In the following description reference will be made mainly on the first edge 10 and the second 12 edge opposite to the first edge 10.

4 fabric covers, at least partially, the front surface of 6 rigid substrate 2. In accordance with one of the forms of realization of weft threads this light-emitting fabric 4 are optical fibers 14. These weft optical fiber beyond the light-emitting surface of the fabric 4 for each of these fibers had a chance to be attached to the light source (Annex drawings is not shown). As variants of realization of optical fibers can be a warp of the light-emitting tissue.

The form of realization of the first ends of optical fibers 14 are bent on 180 degrees about the first edge 10 towards the back surface of 8 rigid substrate 2 and attached to the light sources, which are located on the backside of a rigid substrate 2. The said sources of light are located in lodgement determined within the first block of 16. Here it comes, for example, about the electroluminescent diodes, also known as LEDs. Optical fiber 14 are connected with the help of connectors 18 with nut, well-known specialist in the art, the so-called bottom panel of 20 of the first block 16.

Similarly, the second ends of optical fibers 14 are bent on 180 degrees about the second edge 12 in the direction of the back surface of 8 rigid substrate 2 and attached to the light sources (listed in the Annex not shown) type electroluminescent diodes LED type, located in lodgement determined within the second 22. Optical fiber 14 are connected with the help of connectors with nut 18 on the so-called upper panel of 24 block 20.

The first block of 16 is made, for example, with the use of molded item and, if necessary, cover. In accordance with the preferred form of implementation, presented in the Annex drawings, block has the shape of an elongated parallelepiped held parallel to the first edge 10 (and parallel to the second edge 12) rigid substrate 2. The second block 22 is similar to the first block 16.

The first block of 16, as well as the second block 22, mounted on the rear surface of 8 rigid substrate 2. This mount can be implemented in any suitable in this case, the funds and depends, in particular, on the material from which made this rigid substrate. In the case of hard substrate, which is a gypsum plasterboard, may be considered, for example, gluing units to the rear surface of 8 rigid substrate 2.

In the form of implementation, presented in figure 1, 4 fabric stretched on the front surface of 6 rigid substrate 2 and held tight on the front surface of 6 with two clamps 26.

Each clip 26 presented in this first form of realization in the form of a single profiled part having a cross section of the U-shaped form. Thus, clamp 26 has reason to 28 and two branches of 30.

Base 28, for example, is flat and goes in front of the first edge of the 10 or opposite the second edge 12 rigid substrate 2 essentially the entire length of the corresponding edges. Branches of 30 are connected with the Foundation of 28 thus, to be able to be elastic designated from one another. The free ends of these branches of 30 slightly curved towards the opposite branch 30, forming thus a clip.

Clip 26 is configured in such a way that in the case when this clip is at rest, the distance that separates slightly curved ends of its branches 30, was smaller than the thickness of a rigid substrate 2, plus the thickness of the light-emitting fabric 4 and optical fibers 14. Thus, to install the clip 26, as represented in figure 1, it is necessary to dissolve 30 branches, which then will keep this light emitting 4 fabric to a rigid substrate 2. Clip 26 upon this compresses the appropriate edge of a rigid substrate 2, pressing the light emitting 4 fabric to a rigid substrate 2. Due to its shape clip 26 also provides protection bent 180° part of optical fibers 14.

Figure 2 contains a variant of realization of a complex formed by rigid substrate and light-emitting cloth, in accordance with the proposed invention. This complex represents the same structure as complex, shown in figure 1. However, in the present case, the clip 26, made in the form of a single detail and shown in figure 1 is replaced with the clamp 26', consisting of two parts.

This clip 26' reproduces the structure of the clamp 26, has foundations and two branches of 30'. Each branch of 30' is intended for entry into focus one of the surface of a rigid substrate 2, holding the light emitting surface fabric 4 or optical fiber 14.

The base of the clip 26' allows you to adjust the distance between two branches of 30′. The first branch 30′ equipped with covered in detail 32, while the other branch 30′ supplied by covering part 34, which referred covered in detail 32 has to slide. Provides, for example, the availability of funds into place (listed in the Annex not shown), intended to hold a covered detail 32 in a given position that provides a satisfactory compression light-emitting fabric 4 on the front surface of 6 rigid substrate 2, towards covering details 34.

Complex formed by rigid substrate 2 and light-emitting fabric 4 and presented in figures 1 and 2, can be used as shown, for the implementation of the ceiling. Indeed, such a complex can be placed on the design, implemented under the floor, in order to take finishing elements, also called ceiling slabs. Here it is enough to adapt the size of a rigid substrate 2, taking into account the clips or 26 26′, to the size of the mentioned structure.

Figure 3 shows how complex, presented in figure 1, can also be adapted for implementation of a vertical wall, for example, for the implementation of the partition. Description below is valid for complex, for example, the complex, shown in figure 2, and even to the other developments that integrate a rigid substrate 2 and the light emitting 4 fabric, in case this 4 fabric, for example, adhered to a rigid substrate 2. In addition, figure 3 illustrates the complex in accordance with the proposed invention, which has only one partition surface. However, there is also the possibility, adapting, in particular, accordingly blocks containing light sources, to provide a complex in accordance with the proposed invention, which has two surface the same partition.

In accordance with the method of implementation, presented in figure 3, in schematically presented here partition used shaped elements, known specialist in a given field of technology for the implementation of the partitions. Such partitions are, for example, partitions, called partitions with the butt plate and distributed on the market under the brand Clipper. In the following description of how the surface of the wall can be made, at least partially, shining through, for example, complex, presented in figure 1.

Usually this partition contains lower trailing stiffener 36, not shown here is the upper longitudinal element stiffness, not shown here vertical racks, as well as a rigid substrate 2, which represents, for example, gypsum boards known under the name 13.

In accordance with the form of implementation, presented at the above figure, rigid substrate 2 covered on its front surface of 6 light-emitting fabric 4. The first block of 16 and the second unit 22 fulfilled, every, rigidly connected with profile 38. This angle profile contains two wings, and the first wing of 40 overlaps associated edge of a rigid substrate 2. As for the second wing 42, it binds the block with a matching first wing of 40 and runs along the back surface of a rigid substrate 2. In the case when complex, presented in figure 1, is placed in a vertical position for the implementation of the partition, as shown in figure 3, the first edge 10 is installed horizontally in the down position and the second edge 10 becomes the top edge of a rigid substrate. Thus, the first wing of 40 angular profile 38 corresponding to the first block 16, is support for hard substrate 2, and the first edge 10, or the lower edge, this rigid substrate 2 installed on it the first wing of 40.

As shown in Annex drawings, in particular, on 3 and 4, the first block of 16 held the supporting poles 44. Each stand 44 contains the threaded rod 46, passing through the first block of 16, and support Foundation 48. Nut 50, goes into waterside views of the bottom plate 20 of the first block 16, allows supporting racks 44 hold the first block 16. Since this first block is rigidly connected with his profile 38, the first wing of 40 which bears the appropriate rigid substrate 2, gateposts 44 bear the system formed by rigid substrate 2 and the first block 16, containing light sources. In that case, when an optical fiber 14 envelop the first edge of the 10 or lower edge of a rigid substrate 2, they are outside towards profile 38 (not between this profile and rigid substrate). In this case, implemented thus placement allows free installation of optical fibers 14, not exposing them to mechanical stresses, in particular, influence of its own weight rigid substrate 2. In addition, as already mentioned above, clip 26 also provides protection of the optical fibers 14 and, more specifically, 180° part of the ends of these fibers 14.

Gateposts 44 placed his support base inside the lower 48 longitudinal element of rigidity 36.

To ensure the power supply light sources, which are located in the first block of 16 and in the second block 22, which also provided the electric transformer (not shown). The same transformer can be required for the first block of 16 and for the second unit 22. Can also be provided for the use individual transformers for each of the blocks. In this second case referred to the transformer can be, for example, is integrated in each of the blocks. In both cases, referred to here, one or two electric transformer can be placed between two substrates, forming the information provided here as a partition. Each transformer should be powered by electricity. Such food is realized, for example, with the help of wires passing inside the lower longitudinal element of rigidity 36.

In accordance with the preferred form of the implementation of the dimensional parameters of the first block of 16 and the second unit 22 are defined in such a way that each of them had a chance to perform the function of spacers between two rigid substrates partitions. The rigid substrate 2, not carrying light-emitting tissue depends in the first block of 16 and in the second block 22. Thus, two hard substrate 2 are held in position with one hand, using the first block 16 and the second unit 22, and on the other hand, using longitudinal element of rigidity of this partition.

Form of implementation presented in Annex drawings, provide for the presence of sources of light at each end of the optical fibers 14. Thus, the optical fiber light-emitting fabric 4 supplied light through two of their end. It allows to provide essentially uniform distribution of light across the surface of the fabric, eliminating the diminution of the Ohr, which may appear at the ends of the optical fibers remote from the light source.

Depending on the height partitions and, in particular, height, covered with light-emitting cloth 4, and in the case of, for example, ceiling panels can be considered the option of having only one block from the light source in case this height is reduced. In this case, it is useless output optical fiber 14 light-emitting fabric 4 beyond the two opposite edges. The side of the optical fiber 14 does not appear outside of the appropriate edge not bends, the use of clamp 26, 26′ or similar device is not strictly necessary. This can be provided other means intended for fixing the appropriate end of the light-emitting fabric 4 on the front surface of 6 rigid substrate 2. Clip 26, 26′, or similar means of tightening it only provides the side of the optical fiber 14 are bent towards the back surface of a rigid substrate 2.

4 fabric can generate a large glowing area, distributed along the entire front surface of 6 rigid substrate. However, in some cases only a part of the light-emitting tissue will in the case when the light sources are included. Indeed, can be considered the option of occurrence of light only part of the light-emitting surface tissue for representations of a picture, logo, indication etc. In this latter case, in order to make the invisible figure intended to be lit, in the case when the light sources are redeemed, are invited to cover the light emitting fabric 4 semi-transparent layer. This may be, for example, the layer of paper, the color of which corresponds, for example, the color of the light-emitting tissue. We can also go on a sheet made of a synthetic material providing light scattering. Can also be considered, and other materials such as thin fabric.

The various forms of realization, described above, can get complex, integrating composed of a rigid substrate and the light-emitting textile material, such that the complex can be used as a lining for the implementation of the vertical or horizontal walls, partitions and ceilings. The previous solution has the advantage consists in the possibility of its integration in the classical system of the bearing structure of the wall or ceiling. The adaptation of such technical solution easy to implement, and its cost is limited.

The use of such system also allows to have a design that can be dismantled, which allows to realize the maintenance of the components associated with light-emitting cloth. Indeed, cladding, incorporating light emitting fabric, can be dismantled in just the same way that the so-called "simple" cladding, known from the prior art that you can combine complexes in accordance with the proposed invention for the implementation of the ceiling or walls.

Complex in accordance with the proposed invention allows to ensure the protection of the optical fibers where they are most susceptible to damage, i.e. in the zone where these fibers are bent. In addition, mounting method is proposed for the implementation of the partitions allows you to eliminate the mechanical stresses in these optical fibers created, in particular, the weight of the sold facing the panel.

In case of use for the implementation of the partition blocks used for light sources allow, on the one hand, for the unit, which is located at the bottom, hold the corresponding rigid substrate, and on the other hand, to realize the gap with other rigid substrate forming this partition.

The invention is not limited to those forms of implementation and their variants, which were described in these pages as a non-limiting examples. This invention also refers to any implementation options available to a person skilled in the art and not beyond the following formula of the invention.

So there would be outside the scope of the present invention, the use of light-emitting fabrics, other than the light-emitting fabrics of the type indicated above. Substrate for the light-emitting tissue may also be different from plaster panels. In this case, any hard surface, which may be integrated into the implementation of the partition, such as melamine panel, may also be acceptable.

The above descriptions of specific way adapted to the frame partitions, distributed on the market under the brand Clipper. However, the present invention can also be applied to other types of frames and the preferred way to frameworks designed for measurable dismantle of partitions, or to removable partitions.

Form of implementation of the tightening here also given merely as an illustrative and non-restrictive examples. Thus, instead of using, for example, shaped element, passing essentially the entire length of the corresponding edges of rigid substrates, may be considered, for example, using multiple devices tightening of reduced size, distributed along the edge of a rigid substrate to hold the light-emitting tissue.
