Description

LINEAR RECESSED STRUCTURE FOR LIGHTING

DESCRIPTION

Field of the Invention

The present invention belongs to the technical field of structures and supports for the disposition of lighting systems in ceilings and walls, and more specifically to the recessed into ceilings and walls structures and supports for the disposition of several light sources separated into tracks, fluorescent type, LED and the like.

The invention relates particularly to a linear recessed structure for lighting formed by a metal profile in which is placed the lighting system attached to a gypsum and titanium casting in such way that the metal profile is recessed and the gypsum and titanium casting is adapted to the surface of the ceiling or the wall.

Background of the invention

At present there are known diverse recessed structures for the placement of lighting sources such as fluorescent, LED, and any type of lighting system recessed into the ceiling or walls in a way that to illuminate through a diffuser.

These structures are usually encased or profiles shaped in "C" and are made from plaster, gypsum and similar materials to which once installed on the roof, wall or surface to illuminate is fixed a metal element which contains the lighting system.

These structures have the disadvantage of having to be installed in several stages, at first the gypsum and subsequently the metal elements in which is placed the lighting system, light bulbs, spots, fluorescent, LED, etc. Furthermore these structures do not allow the employment of systems of great length, having to overlap several of them to install linear lights of great length.

Therefore it is desirable a recessed structure to allow the employment of linear lighting systems of great length avoiding the existing disadvantages of the above

structures prior art.

Pctütion of the invention The present invention solves the problems existing prior art through a linear recessed structure for lighting, having a linear metal profile with a tt' shaped section whose two lateral segments, or legs, are each inserted in a casting of gypsum and titanium.

The linear metal profile provides fixing elements in its inner surface for the fixing of different light sources such as fluorescent, halogen spots, LED lamps, etc. In the resulting structure the linear metal profile with the lighting sources is recessed without frame into a conventional ceiling or a wall, as well as into a suspended ceiling while the casting from gypsum and titanium is adapted to the surface of the ceiling or wall, remaining substantially aligned with it. This provides a linear lighting system, i.e. of great length in comparison to its other dimensions, and continuous, i.e. without interruptions. Thus the length of the lighting system can be unlimited, according to the specifications of the installer.

For the accomplishment of the structure which is the object of the present invention molding is used. A metal profile is placed in the corresponding mold and fiberglass is introduced in the area of the lateral profile segments or legs. Then the liquid mixture of gypsum and titanium is introduced in the mold around the metal profile, and allowed to set. Once the structure is obtained with the bonded materials, it is ready to be attached to the ceiling or wall, and then simply and immediately to set the lighting sources inside.

These castings can be made preferentially in a Crismosil® base, presenting a high mechanical resistance to torsion and to buckling as well as a high hardness.

Particularly, the linear structure object of the present invention has a diffuser for the light emitted by the light sources, which is preferably a diffusing plate or surface by means of fixing to the open side of the metal profile, leaving enclosed in its interior the light sources.

On a preferable basis, to reinforce the gypsum and titanium castings and make them more resistant, they may present glass fibers as reinforcement, disposed at 3 --least in areas of insertion of the ateral segments of the metal profile, although they may be included in different areas.

Detailed description of the invention

The object of the present invention isa linear recessed structure for lighting.

As shown in the figures, this structure is formed by a linear metal profile 1 and a casting 2 from gypsum and titanium.

The linear metal profile 1 presents a section in "0" and it has on its inner surface fixing elements 12 for the installation of light sources 11.

Preferably the metal profile 1 is a profile from extruded aluminum, although it can also be obtained by extrusion or molding of other light and resistant metals.

Figures 9, 10 and 11 show particular embodiments of the invention in which the linear metal profile 1 of section in "0" is formed by a first element 14 with an inverted "U" section and attached to each of its side is a lateral wing 15. These lateral wings 15 can be attached to the sides of the first element 14 by conventional fixing means, Through these embodiments is obtained the advantage of lightening the weight of the structure due to the reduction of the material for the castings (2) from gypsum and titanium with a consequent reduction in the weight of the structure and savings in manufacturing costs.

The two lateral segments 4, or legs of the above-mentioned section in "0" of the metal profile 1, are each inserted in a casting 2 from gypsum and titanium.

By these means, the metal profile 1 is recessed into a ceiling or a wall, adapting the castings 2 from gypsum and titanium to the surface 6 of the ceiling or the wall. As can be seen on Figures 4-3, these castings 2 present different shapes in order to adapt to the surface 6 where the structure is installed.

According to a preferable implementation of the invention shown in the figures, the castings 2 from gypsum and titanium present glass fibers 3 as reinforcement arranged at least in areas of insertion of the lateral segments 4 of the metal profile 1 to strengthen the bond with the metal section 1 and achieve a more resistant structure.

For the obtaining of the linear recessed structure for lighting object of the invention molding is used. To that end a metal profile 1 is placed in the corresponding mold 7 and glass fibers 3 are introduced in the area of the lateral segments 4 or legs of the section in Q1 of the metal profile 1. Then, from a casting bucket 8 the liquid mixture 9 of gypsum and titanium is introduced into the mold 7, around the metal profile 1, and allowed to set. Once the structure is obtained from the bonded materials, it is ready to be fixed into the ceiling or wall, and then simply and immediately to set the light sources 11 in its interior by the strap retainer 13 of the above-mentioned light sources 11.

These molded parts 2 may be made preferably using a Crismosil® base, showing a high mechanical resistance to torsion and to buckling as well as a high hardness.

In particular, the recessed structure presents a diffuser 10, which is fixed to the open side of the metal profile 1, closing it and leaving in its interior the light sources 11, enabling the passing through of the light emitted by the above-mentioned light sources.

According to a particular implementation of the invention, this diffuser lOis plate-shaped, from a thermoplastic material that is preferentially an acrylic material.

Preferably, this diffuser 10 is fixed to the metal profile 1 by means of clipping, which provides a very fast and simple assembly and disassembly for replacement or repair of the light sources.

Once clearly described the invention, it is noted that the particular implementation described above are subjects to modifications of detail provided they do not alter the fundamental principle and essence of the invention.
