Definitions

  • the present invention belongs to the technical field of walls or floors cladding or paving, or any other surface cladding with translucent slabs or tiles; more particularly to the slabs or tiles lightning systems, which provide lighting at the back of such claddings.
  • the lighting systems have evolved such that nowadays there are slabs in which the lighting means form part of the slabs themselves, so that when installing a cladding with them, light travels through them and generates the desired lighting effect. Nevertheless, these self-illuminated slabs and their lighting means present some drawbacks.
  • One of these drawbacks appears in floor claddings, which are exposed to greater loads than other surfaces like walls or ceilings and, therefore, the lighting means located under these floor slabs must include complicated support means for the loads in order to create a space in which to locate the lighting means without smashing them.
  • the referenced document ES2313684 defines a luminous slab that comprises a transparent or translucent slab made of a material resistant to mechanical stresses, a printed circuit board, a spacer to hermetically secure said slab to the printed circuit board by means of an adhesive and a sealant layer made of silicone.
  • a series of LEDs mounted thereon and a diode and a resistance connected to these LEDs, whereas on the side of the printed circuit board facing downwards, there are two electrical contacts connected by means of a tin soldered union to two electrical cables in order to make an additional connection to a power source.
  • the spacer is located between the slab and the printed circuit board such that the upper side of said spacer is in contact with the slab and the lower side of said spacer is in contact with the side of the printed circuit board facing the slab, thus forming a sealed space between said slab, the printed circuit board and the spacer, where said LEDs are located.
  • the spacer and the printed circuit board lateral surfaces are recessed from the slab peripheral edge, and the sealing layer is applied surrounding said lateral surfaces until it reaches said slab peripheral edge, so that the whole slab set is sealed at the lateral and rear sides.
  • the slab and the printed circuit board are constrained to each other's size and shape, so that their manufacture is connected and does not allow a great variety of slab shapes and sizes to be used, given the fact that if the slabs are to be made outside the standard sizes and shapes, the printed circuit board has to be custom made, which implies a greater cost.
  • the way in which the slab, printed circuit board and spacer are mounted implies that when one of these elements fails or breaks all the elements of the set must be replaced, thus increasing maintenance costs.
  • the referenced document WO2012140280 describes a texturised luminous slab that comprises a base or support, upon which surface electronic lighting means are uniformly distributed and wherein said support and electronic lighting means are covered by a texturised finish, transparent or translucent, and configured to withstand mechanical loads.
  • the slab and the lighting means are joined, being the slab body itself the support for the lighting means, so that, again, in the event of a replacement, all the ensemble must be replaced, thus increasing costs.
  • the lighting effect achieved with these slabs is concentrated in the precise point in which the lighting devices are located, given that there is no system or mechanism that collaborates in widening their action range, therefore the achieved effect is far from being a slab homogeneous lighting.
  • a transparent or translucent cladding slabs backlighting system comprising:
  • each lighting module comprises:
  • a light transmitting body located behind the transparent or translucent cladding slabs configured to support said slabs; • electrical lighting means mounted to the light transmitting body and comprising a plurality of lighting devices arranged to introduce light into the light transmitting body, in use; and
  • module connection means mounted to the light transmitting body and configured for electrically connecting the lighting means of each lighting module with the lighting means of at least two contiguous lighting modules.
  • a significant advantage over the state of the art is achieved because it makes the slab lighting system structurally independent of the slabs layer, so that in the event of a lighting system malfunction, or even in the event of a slab wearing out or fracture, it is possible to replace or mend the lighting means while keeping the same slab, or, to replace the defective slab while keeping the same lighting means.
  • the plurality of lighting modules may be electrically connected in series separately in two independent electrical phases. With this connection mode, the lifetime of the slabs backlighting system is considerably extended and maintenance costs are reduced.
  • the first securing means may be configured to reversibly secure the lighting modules to the surface to be cladded.
  • a reversible securance or fastening helps to easily remove a defective or malfunctioning lighting module from the surface to be cladded and replace it with a new one.
  • the first securing means may comprise a cement layer whose securing properties are affected by heat or vibration, so that when applying one of these to the lighting module it will come off easily from the cladded surface, thus making the maintenance fast and low cost
  • the second securing means may be configured to reversibly secure the lighting modules to the transparent or translucent cladding slabs.
  • the second securing means may comprise a double-sided adhesive layer whose adhesive properties are affected by heat, cold or a specific solvent, so that when applying one of these to the back of the slab, it will come off easily from the lighting modules, thus making their replacement fast and low cost.
  • the light transmitting body may comprise a light guide material, such as a light guide panel.
  • a light guide plate or panel is an acrylic panel typically made from pure PMMA resin. PMMA is extremely transparent, mechanically resistant and highly weather resistant, and lasts longer than 30 years on average.
  • a matrix of lines or dots may be etched, for example, with laser, known as V-cutting, the lines or dots can also be printed, or a combination of both, or particulates may be added into the panel itself. The purpose of all methods is to direct light out the front of the panel.
  • a light transmitting body comprising a light guide material is strong enough to support the typical loads of a floor slab without causing the slab or the light transmitting body to crack or break by said typical floor loads. Besides, it is moisture resistant as well, so such material is not be adversely affected by cleaning processes using water.
  • the light transmitting body may comprise a containment box made of a translucent or transparent material and formed by a first hollow body, which presents a straight prism shape with a first closed base suitable to be located in contact with the surface to be cladded; a second opposite open base; and sides which perpendicular dimension to both bases is smaller than the rest of the box dimensions; and, a second body located over the second open base, such that the union of the first and second bodies forms an inner hollow chamber.
  • Each lighting module may comprise electrical lightning means located in the inner hollow chamber.
  • a light transmitting body comprising a containment box that defines an inner hollow chamber is also suitable to support the loads typically encountered by floor slabs and the electrical lighting means can be located in the inner hollow chamber so that the floor slabs loads do not smash them. Additionally, the electrical lighting means located in the inner hollow chamber are protected from moisture arising from spillages or cleaning processes.
  • Another advantage of the containment box is that it protects the lighting means located in its interior, either against mechanical pressure or against moisture, so that it is a lighting system able to be located on any surface, including floor surfaces, which present more problems due to the supported loads and the possibility of moisture ingress through the joints.
  • each lighting module may comprise means for widening the range of action of said lighting devices located in the inner hollow chamber. This enhances the homogeneous distribution of light behind the transparent or translucent slabs thus avoiding the appearance of light spots when the slabs are viewed from the front.
  • the electrical lighting means mounted to the light transmitting body and comprising a plurality of lighting devices arranged to introduce light into the light transmitting body, in use may comprise LED strips or bands.
  • LED strips are very convenient lighting means due to their low cost, low electricity consumption and long lifetime, which all translates to low maintenance costs.
  • the electrical lighting means mounted to the light transmitting body and comprising a plurality of lighting devices arranged to introduce light into the light transmitting body, in use are waterproof, i.e. they prevent water ingress to the lighting devices, for example the electrical lighting means may comprise waterproof LED strips.
  • the LED strips are located on opposite sides of the light transmitting bodies. This configuration produces a more homogeneous distribution of the light behind the translucent slabs.
  • the LED strips are located on slots on opposite sides of the light transmitting bodies. This configuration produces a more compact backlighting system which is faster to assemble and easier to maintain and also prevents the LED strips from being smashed by the floor slabs loads.
  • the light transmitting body may comprise a heat conductive layer configured to dissipate the heat generated by the electrical lighting means.
  • a heat conductive layer configured to dissipate the heat generated by the electrical lighting means, the lifetime of said electrical lighting means is extended.
  • the heat conductive layer may partly surround one side of the light transmitting body, preferably the side that is facing the surface to be cladded.
  • the heat conductive layer may comprise an aluminium layer.
  • the aluminium layer may be glued to one side of the light transmitting body, preferably the side that is facing the surface to be cladded.
  • the heat conductive layer may define a plurality of formations, such as protrusions and/or dents, like for example corrugations, dots or grooves for improving the securance or fastening of the light transmitting body to the first securing means.
  • the electrical lighting means are located on slots on opposite sides of the light transmitting body and the heat conductive layer covers the electrical lighting means and the side of the light transmitting body that faces the surface to be cladded.
  • the electric lighting means comprise at least an electrical connections base part, located in the first body, wherein the plurality if lighting devices are connected to said electrical connections base part.
  • the module connection means of the lighting means comprise in one end of each electrical connections base part, a male connection plug with an adjacent first electrical connections base part and in another end of each electrical connections base part, a female connection plug with an adjacent second electrical connections base part so that each electrical connections base part is connected with at least an electrical connections base part of an adjacent lighting module, in use, forming a electrical connection in series of the adjacent lighting modules.
  • the system connection means is formed by a connection to an electrical grid transformer, located in a first electrical connections base part corresponding to the lighting module of the series connection located closer to one of the ends of the surface to be cladded and close to said transformer and, wherein the last electrical connections base part, corresponding to the module located at the end of the series connection of all electrical connections base part, comprises a closure cap of the female connection plug.
  • the slab backlighting system comprises a single electrical connections base part, formed by an electrical connections board, located on the first base of the first body and wherein the plurality of lighting means are equidistantly located on the surface of the electrical connections board.
  • the at least single electrical connections base part is formed by a first rod, located in the first body of the box secured on a first side of the body and the plurality of lighting devices are equidistantly located along the rod's length.
  • the lighting system comprises a second rod longitudinally located on a second side of the first box body opposite the first side.
  • the lighting system comprises diffusing means for the light generated by the lighting devices.
  • said light diffusing means are formed by a first laminar planar body, with the same shape as the first and second base of the first box body and it is secured to the box sides in a closer position to the second body than the plurality of lighting devices secured to the at least one electrical connections base part.
  • the means for widening the range of action of the lighting devices are formed by a plurality of semi-spherical protrusions that emerge from the box second body in an opposite direction to the inner hollow chamber and where each protrusion is located so as to match the location over a lighting device connected to the board, respectively.
  • the means for widening the range of action of the lighting devices are formed by a second polymeric laminar body located on the box inner chamber at the same height than the lighting devices, which comprises in its surface a plurality of longitudinal slots located in perpendicular direction to the longitudinal direction of the at least one electrical connections base part.
  • the first securing means of the lighting module to the surface to be cladded is cement.
  • the second securing means of the lighting module to the cladding slab are formed by an adhesive.
  • system activation means are fomed by a switch for each lighting phase.
  • This slabs lighting system allows the use of lighting devices formed by leds, halogens or any other light source. Furthermore, the supplied light may be cold, warm and of any voltage.
  • each lighting module is connected by an electrical connections base part, and these parts are connected between each other by one of their ends, so that these connections are made beneath the slabs and in such a way that only electric cable passes from one lighting module to the next, so that the connection is made in their interior, but because the lighting modules are consecutively and adjacently disposed over the whole surface to be cladded, there are no electrical connections outside the lighting modules, so that these connections are perfectly protected against external moisture and loads.
  • Another important advantage of this lighting system is its simplicity, which only requires the connection between the electrical connections base parts and these connections are completely independent from the slab installation, and this is the reason why the cost and time of installing the slabs is reduced.
  • the boxes present the same shape and size than the slabs, or, for example, in the case of less common slab shapes, the boxes present a different size or shape than the slabs, not being necessary to make custom boxes for said cases, so that it is possible to make the boxes in large batches and storing them for using them when there is a demand, thus reducing their cost.

Abstract

This invention provides a lighting module for forming a transparent or translucent cladding slabs backlighting system. The lighting module comprises a light transmitting body to be located behind transparent or translucent cladding slabs and configured to support said slabs when they are used as floor cladding. The lighting module also comprises electrical lighting means (6) mounted to the light transmitting body which comprise a plurality of lighting devices arranged to direct light trough the light transmitting body, in use; and connection means mounted to the light transmitting body and configured for electrically connecting the lighting means of each lighting module with lighting means of at least two contiguous lighting modules, in use. A transparent or translucent cladding slabs backlighting system made using said lighting modules is also provided. The system comprises the modules electrically separately connected in series in two independent electrical phases. The lighting modules may comprise light guide panels or translucent or transparent containment boxes that support the typical loads on the floor. The lighting system made with this lighting module is structurally independent from the cladding slabs (1), such that their shape is not mutually dependent and their replacement is also mutually independent, meaning the replacement of one slab does not imply the replacement of a lighting module, and vice versa.

Description

DESCRIPTION
Translucent slabs backlighting system Technical field
The present invention belongs to the technical field of walls or floors cladding or paving, or any other surface cladding with translucent slabs or tiles; more particularly to the slabs or tiles lightning systems, which provide lighting at the back of such claddings.
Background to the invention
Currently there is a great tiles or slabs variety in the cladding systems field which vary in terms of material, colour, resistance, finish, etc. Thanks to the most recent advances, another characteristic that is feasible to add to the cladding characteristics is lighting.
Thus, in the beginning, the provision of lighting means was achieved by embedding them among the slabs, with which it was possible to impart greater luminosity or even introduce messages or decorative lighting effects to certain spaces.
After these initial steps, the lighting systems have evolved such that nowadays there are slabs in which the lighting means form part of the slabs themselves, so that when installing a cladding with them, light travels through them and generates the desired lighting effect. Nevertheless, these self-illuminated slabs and their lighting means present some drawbacks. One of these drawbacks appears in floor claddings, which are exposed to greater loads than other surfaces like walls or ceilings and, therefore, the lighting means located under these floor slabs must include complicated support means for the loads in order to create a space in which to locate the lighting means without smashing them.
Moreover, in current lighting systems, it is necessary to leave a space of between 10 to 15 cm between the slab and the cladding surface, in order to achieve an appropriate and homogeneous lighting effect. In practice, this implies that installing these illuminated cladding systems on the floor is almost impossible, given that the support is not consistent enough and generates slabs cracks and fractures when stepping on them. This additional space requirement is also another disadvantage when cladding walls and ceilings because it reduces the habitable space of the cladded rooms.
Another disadvantage of these lighting systems is that in most occasions the lighting means are incorporated to the slab itself, with the consequence that when the lighting system fails, it is necessary to replace the whole slab (including the lighting means), thus increasing maintenance costs.
Moreover, the installation of these slabs with the integrated lighting means implies the need to hire electrical technicians, thus making the installation process more difficult and increasing installation times and costs.
As an example of state-of-the-art, the following documents can be referenced: ES2313684 and WO2012140280.
The referenced document ES2313684 defines a luminous slab that comprises a transparent or translucent slab made of a material resistant to mechanical stresses, a printed circuit board, a spacer to hermetically secure said slab to the printed circuit board by means of an adhesive and a sealant layer made of silicone. On the side of the printed circuit board that faces the slab there is a series of LEDs mounted thereon and a diode and a resistance connected to these LEDs, whereas on the side of the printed circuit board facing downwards, there are two electrical contacts connected by means of a tin soldered union to two electrical cables in order to make an additional connection to a power source. The spacer is located between the slab and the printed circuit board such that the upper side of said spacer is in contact with the slab and the lower side of said spacer is in contact with the side of the printed circuit board facing the slab, thus forming a sealed space between said slab, the printed circuit board and the spacer, where said LEDs are located. Moreover, the spacer and the printed circuit board lateral surfaces are recessed from the slab peripheral edge, and the sealing layer is applied surrounding said lateral surfaces until it reaches said slab peripheral edge, so that the whole slab set is sealed at the lateral and rear sides. This invention aims to reduce the difficulty of the installation and the electrical consumption, but still has its drawbacks, given that the slab installation requires placing the electric cables in the slab joints in order to lead them to a power source.
Therefore, this installation procedure is slow and painstaking. Moreover, it has to be carried out thoroughly so that the cables are not visible and they do not become loose in the joints. Another requirement is that the joints must be perfectly sealed in order to avoid moisture ingress that could affect the cables.
Also in this case, the slab and the printed circuit board are constrained to each other's size and shape, so that their manufacture is connected and does not allow a great variety of slab shapes and sizes to be used, given the fact that if the slabs are to be made outside the standard sizes and shapes, the printed circuit board has to be custom made, which implies a greater cost.
Moreover, the way in which the slab, printed circuit board and spacer are mounted implies that when one of these elements fails or breaks all the elements of the set must be replaced, thus increasing maintenance costs.
The referenced document WO2012140280 describes a texturised luminous slab that comprises a base or support, upon which surface electronic lighting means are uniformly distributed and wherein said support and electronic lighting means are covered by a texturised finish, transparent or translucent, and configured to withstand mechanical loads.
In this case, the slab and the lighting means are joined, being the slab body itself the support for the lighting means, so that, again, in the event of a replacement, all the ensemble must be replaced, thus increasing costs. In the same way as before, it is impossible to carry out a manufacture in series of the lighting means so that they are compatible with any shape and size of slab, given that both are joined and form a single unit. This limits the options of slab sizes and shapes that can be used.
It can be seen that these are slabs which are bound to the lighting means sizes and shapes and that, in the cases in which the cables are located between the slabs, it is complicated to use them to clad floors because they are more exposed to moisture due to spillages or even due to floor cleaning. Likewise, the use of slabs in floor cladding is complicated when the lighting means are located between the slab and the floor surface in a hollow space created by spacers, which, if they do not exhibit an appropriate mechanical resistance, it causes the smashing of the lighting means.
Moreover, the lighting effect achieved with these slabs is concentrated in the precise point in which the lighting devices are located, given that there is no system or mechanism that collaborates in widening their action range, therefore the achieved effect is far from being a slab homogeneous lighting.
Description of the invention
According to a first aspect of the invention there is provided a transparent or translucent cladding slabs backlighting system comprising:
• a plurality of transparent or translucent cladding slabs arranged in a layer;
• a plurality of lighting modules arranged in a layer placed behind the slabs layer and structurally independent from it, the lighting modules contiguously located among themselves and electrically connected in series, whereby said lighting modules are located on a surface to be cladded and between said surface and the cladding slabs layer;
• system connection means of said lighting modules with the electric grid;
• backlighting system activation means;
• first securing means for securing the lighting modules to the surface to be cladded; and
• second securing means for securing the lighting modules to the transparent or translucent cladding slabs. wherein each lighting module comprises:
• a light transmitting body located behind the transparent or translucent cladding slabs configured to support said slabs; • electrical lighting means mounted to the light transmitting body and comprising a plurality of lighting devices arranged to introduce light into the light transmitting body, in use; and
• module connection means mounted to the light transmitting body and configured for electrically connecting the lighting means of each lighting module with the lighting means of at least two contiguous lighting modules.
These transparent or translucent cladding slabs backlighting systems described above present a low maintenance cost. This is because in the event of a slab fracture or a lighting module malfunction, it is only necessary to replace the fractured slab or the malfunctioning lighting module, respectively, without needing to replace the other element, i.e. the lighting module or the slabs, respectively. This is possible because the lighting modules, lighting devices mounted thereto and their connections also mounted thereto are located behind the slabs and are structurally independent from the slans and therefore it is possible to remove a broken slab without interfering with the lighting module and it is possible to replace a lighting module without breaking any slab.
With the hereby proposed lighting system, a significant advantage over the state of the art is achieved because it makes the slab lighting system structurally independent of the slabs layer, so that in the event of a lighting system malfunction, or even in the event of a slab wearing out or fracture, it is possible to replace or mend the lighting means while keeping the same slab, or, to replace the defective slab while keeping the same lighting means.
The plurality of lighting modules may be electrically connected in series separately in two independent electrical phases. With this connection mode, the lifetime of the slabs backlighting system is considerably extended and maintenance costs are reduced.
The first securing means may be configured to reversibly secure the lighting modules to the surface to be cladded. In this case, a reversible securance or fastening helps to easily remove a defective or malfunctioning lighting module from the surface to be cladded and replace it with a new one. For example, the first securing means may comprise a cement layer whose securing properties are affected by heat or vibration, so that when applying one of these to the lighting module it will come off easily from the cladded surface, thus making the maintenance fast and low cost The second securing means may be configured to reversibly secure the lighting modules to the transparent or translucent cladding slabs. In this case, a reversible securance or fastening helps to easily remove a broken or cracked slab from the lighting modules layer and replace it with a new one. For example, the second securing means may comprise a double-sided adhesive layer whose adhesive properties are affected by heat, cold or a specific solvent, so that when applying one of these to the back of the slab, it will come off easily from the lighting modules, thus making their replacement fast and low cost.
In some embodiments, the light transmitting body may comprise a light guide material, such as a light guide panel. A light guide plate or panel is an acrylic panel typically made from pure PMMA resin. PMMA is extremely transparent, mechanically resistant and highly weather resistant, and lasts longer than 30 years on average. On the bottom of the panel a matrix of lines or dots may be etched, for example, with laser, known as V-cutting, the lines or dots can also be printed, or a combination of both, or particulates may be added into the panel itself. The purpose of all methods is to direct light out the front of the panel.
A light transmitting body comprising a light guide material is strong enough to support the typical loads of a floor slab without causing the slab or the light transmitting body to crack or break by said typical floor loads. Besides, it is moisture resistant as well, so such material is not be adversely affected by cleaning processes using water.
Alternatively, the light transmitting body may comprise a containment box made of a translucent or transparent material and formed by a first hollow body, which presents a straight prism shape with a first closed base suitable to be located in contact with the surface to be cladded; a second opposite open base; and sides which perpendicular dimension to both bases is smaller than the rest of the box dimensions; and, a second body located over the second open base, such that the union of the first and second bodies forms an inner hollow chamber. Each lighting module may comprise electrical lightning means located in the inner hollow chamber.
A light transmitting body comprising a containment box that defines an inner hollow chamber is also suitable to support the loads typically encountered by floor slabs and the electrical lighting means can be located in the inner hollow chamber so that the floor slabs loads do not smash them. Additionally, the electrical lighting means located in the inner hollow chamber are protected from moisture arising from spillages or cleaning processes.
Another advantage of the containment box is that it protects the lighting means located in its interior, either against mechanical pressure or against moisture, so that it is a lighting system able to be located on any surface, including floor surfaces, which present more problems due to the supported loads and the possibility of moisture ingress through the joints.
In some embodiments, each lighting module may comprise means for widening the range of action of said lighting devices located in the inner hollow chamber. This enhances the homogeneous distribution of light behind the transparent or translucent slabs thus avoiding the appearance of light spots when the slabs are viewed from the front.
In some embodiments, the electrical lighting means mounted to the light transmitting body and comprising a plurality of lighting devices arranged to introduce light into the light transmitting body, in use, may comprise LED strips or bands.
LED strips are very convenient lighting means due to their low cost, low electricity consumption and long lifetime, which all translates to low maintenance costs.
In preferred embodiments, the electrical lighting means mounted to the light transmitting body and comprising a plurality of lighting devices arranged to introduce light into the light transmitting body, in use, are waterproof, i.e. they prevent water ingress to the lighting devices, for example the electrical lighting means may comprise waterproof LED strips.
In preferred embodiments, the LED strips are located on opposite sides of the light transmitting bodies. This configuration produces a more homogeneous distribution of the light behind the translucent slabs.
In some preferred embodiments, the LED strips are located on slots on opposite sides of the light transmitting bodies. This configuration produces a more compact backlighting system which is faster to assemble and easier to maintain and also prevents the LED strips from being smashed by the floor slabs loads.
In preferred embodiments, the light transmitting body may comprise a heat conductive layer configured to dissipate the heat generated by the electrical lighting means. By providing a heat conductive layer to dissipate the heat generated by the electrical lighting means, the lifetime of said electrical lighting means is extended.
The heat conductive layer may partly surround one side of the light transmitting body, preferably the side that is facing the surface to be cladded.
In preferred embodiments, the heat conductive layer may comprise an aluminium layer. The aluminium layer may be glued to one side of the light transmitting body, preferably the side that is facing the surface to be cladded.
In preferred embodiments the heat conductive layer may define a plurality of formations, such as protrusions and/or dents, like for example corrugations, dots or grooves for improving the securance or fastening of the light transmitting body to the first securing means.
In a most preferred embodiment, the electrical lighting means are located on slots on opposite sides of the light transmitting body and the heat conductive layer covers the electrical lighting means and the side of the light transmitting body that faces the surface to be cladded.
According to a preferred embodiment, the electric lighting means comprise at least an electrical connections base part, located in the first body, wherein the plurality if lighting devices are connected to said electrical connections base part. The module connection means of the lighting means comprise in one end of each electrical connections base part, a male connection plug with an adjacent first electrical connections base part and in another end of each electrical connections base part, a female connection plug with an adjacent second electrical connections base part so that each electrical connections base part is connected with at least an electrical connections base part of an adjacent lighting module, in use, forming a electrical connection in series of the adjacent lighting modules.
Likewise, the system connection means is formed by a connection to an electrical grid transformer, located in a first electrical connections base part corresponding to the lighting module of the series connection located closer to one of the ends of the surface to be cladded and close to said transformer and, wherein the last electrical connections base part, corresponding to the module located at the end of the series connection of all electrical connections base part, comprises a closure cap of the female connection plug.
In this case and according to a preferred embodiment, the slab backlighting system comprises a single electrical connections base part, formed by an electrical connections board, located on the first base of the first body and wherein the plurality of lighting means are equidistantly located on the surface of the electrical connections board.
In the same case and in other preferred embodiment, the at least single electrical connections base part is formed by a first rod, located in the first body of the box secured on a first side of the body and the plurality of lighting devices are equidistantly located along the rod's length.
In this case in which at least an electrical connections base part is formed by a first rod and according to a preferred embodiment, the lighting system comprises a second rod longitudinally located on a second side of the first box body opposite the first side.
In the case that the electrical connections base part is formed by a first rod as well as when it is formed by both first and second rods, and according to a preferred embodiment, the lighting system comprises diffusing means for the light generated by the lighting devices.
According to a preferred embodiment, said light diffusing means are formed by a first laminar planar body, with the same shape as the first and second base of the first box body and it is secured to the box sides in a closer position to the second body than the plurality of lighting devices secured to the at least one electrical connections base part.
According to a preferred embodiment, in the case that the electrical connections base part is formed by an electrical connections board, the means for widening the range of action of the lighting devices are formed by a plurality of semi-spherical protrusions that emerge from the box second body in an opposite direction to the inner hollow chamber and where each protrusion is located so as to match the location over a lighting device connected to the board, respectively.
In the case that at least one electrical connections base part is formed either by a first rod as well as by both first and second rods and according to a preferred embodiment, the means for widening the range of action of the lighting devices are formed by a second polymeric laminar body located on the box inner chamber at the same height than the lighting devices, which comprises in its surface a plurality of longitudinal slots located in perpendicular direction to the longitudinal direction of the at least one electrical connections base part. According to a preferred embodiment, the first securing means of the lighting module to the surface to be cladded is cement.
According to a preferred embodiment, the second securing means of the lighting module to the cladding slab are formed by an adhesive.
On another hand, according to a preferred embodiment, the system activation means are fomed by a switch for each lighting phase.
This slabs lighting system allows the use of lighting devices formed by leds, halogens or any other light source. Furthermore, the supplied light may be cold, warm and of any voltage.
Furthermore, the existing lighting devices in each lighting module are connected by an electrical connections base part, and these parts are connected between each other by one of their ends, so that these connections are made beneath the slabs and in such a way that only electric cable passes from one lighting module to the next, so that the connection is made in their interior, but because the lighting modules are consecutively and adjacently disposed over the whole surface to be cladded, there are no electrical connections outside the lighting modules, so that these connections are perfectly protected against external moisture and loads.
Thanks to the means for widening the range of action of the lighting devices, as well as to the light diffusing means, a much more general and homogeneous slab lighting is achieved, less localized. Furthermore, the connection of the lighting devices in two phases extends the lifetime of the lighting system.
Another important advantage of this lighting system is its simplicity, which only requires the connection between the electrical connections base parts and these connections are completely independent from the slab installation, and this is the reason why the cost and time of installing the slabs is reduced. Besides, by being independent the lighting system from the slabs, it is possible that, according to the needs, the boxes present the same shape and size than the slabs, or, for example, in the case of less common slab shapes, the boxes present a different size or shape than the slabs, not being necessary to make custom boxes for said cases, so that it is possible to make the boxes in large batches and storing them for using them when there is a demand, thus reducing their cost.
All this results in a simple, economic and effective slab lighting system.
According to a second aspect of the invention there is provided a lighting module for forming a transparent or translucent cladding slabs backlighting system, the lighting module comprising:
• a light transmitting body to be located behind transparent or translucent cladding slabs configured to support said slabs;
• electrical lighting means mounted to the light transmitting body and comprising a plurality of lighting devices arranged to direct light trough the light transmitting body, in use; and
• module connection means mounted to the light transmitting body and configured for electrically connecting the lighting means of each lighting module with lighting means of at least two contiguous lighting modules, in use.
The skilled person is to understand that any features of the first aspect of the invention are likewise meant to be applicable to the second aspect of the invention, without departing from the scope of the claims and invention.

Detailed description of the embodiments
Figure 1 shows a lighting module according to a first embodiment of the invention. The lighting module 100 comprises a light transmitting body 102, which in this case is a polymethyl metacrylate (PMMA) light guide panel supplied by Mitsubishi. The light guide panel 102 comprises an array of laser-etched dots 104 uniformly distributed on one side 106 with a spacing of 1 to 2 mm between adjacent dots, which, in use, refract and/or reflect the light entering by two opposite sides 108, 1 10 of the light guide panel 102. The etchings 104 direct the light towards the light guide panel surface 1 12 opposite to the side 106 comprising the dot etchings 104. In this way, the light guide panel 102 serves to redirect as much light as possible from the lighting devices towards the back of the cladding slabs, in use. This light guide panel etchings pattern also achieves a uniform light distribution when viewed through translucent cladding slabs, in use. Another advantage is that the light guide panel 102 withstands the loads typically encountered on floor slabs and thus, neither the slabs nor the light guide panel will break when used in floor claddings. The light guide panel measures 600 mm wide, 600 long and 8 mm thick, but any other dimensions are likely to be equally appropriate. The lighting module 100 comprises electrical lighting means 1 14 mounted to the light guide panel 102 and comprising a plurality of lighting devices 1 16 arranged to direct light through the light guide panel 102. In this embodiment, the electrical lighting means are a pair of LED strips 1 14, each located on one opposite edge 108, 1 10 of the light guide panel 102 and the lighting devices are individual LED units 1 16 in each LED strip 1 14.
These LED strips 1 14 are waterproof, i.e. they prevent the ingress of moisture and water to the LED units 1 16. The LED strips 1 14 supply, in use, 3850 ± 5 % lumens of light and work under a 24 Volts tension and 0.57 Amps direct current, for improved safety, consuming only 14 ± 5 % Watts. The achieved lighting effect is roughly 48 lumens per Watt.
The lighting module 100 comprises module connection means 1 18, 120 mounted to the light guide panel 102 and configured for electrically connecting the LED strips 1 14 of the lighting module 100 with the lighting means of at least two contiguous lighting modules, in use. In this embodiment, the module connections means are a female and a male electrical connection plugs 1 18, 120, respectively, and are located on the light guide panel edges or sides 122, 124 perpendicular to the edges or sides 108, 1 10 where the LED strips 1 14 are mounted. This arrangement facilitates the rapid and cost effective installation of a cladding comprising numerous lighting modules like this one, without needing to hire an electric technician, since the electrical connections within the lighting modules are already made prior to their installation and the only connections to be made during installation is by plugging between different lighting modules.
Additionally, this lighting module 100 comprises a heat conductive layer 126, which in this case is an aluminium layer that covers one side of each LED strip 1 14 and the side 106 of the light guide panel 102 comprising the elongate etchings 1 14. This aluminium layer 126 dissipates the heat produced by the LED strips 1 14 in use and comprises a series of uniformly distributed corrugations (not visible) that help securing the lighting module 100 to the surface to be cladded during the installation process. According to the further drawings provided, it can be seen that in a second preferred embodiment, the slabs (1 ) lighting system, the slabs (1 ) being translucent or transparent, used for the cladding of walls, floors or any other surface, hereby presented, comprises a series of lighting modules located contiguously to each other, wherein said lighting modules are located on the surface (2) to be cladded and intermediately between this surface (2) and the cladding slabs (1 ), a system connecting means of said lighting modules with the electrical grid and system activation means.
Likewise, each system lighting module comprises a containment box (3) made of a translucent material, electrical lighting means, first securing means to the surface (2) and, second securing means to the cladding slab or tile (1 ).
The containment box (3), as shown in Figure 2, is formed by a first hollow body (4) with a straight prism shape formed by a first closed base (4.1 ) suitable to be located in contact with the surface to be cladded, a second opposite open base and sides (4.2) which perpendicular dimension to both bases is smaller than any other box dimension (3) and, a second body (5) located on the second open base such that the first and second body (4, 5) together define an inner hollow chamber.
On another hand, the electrical lighting means of each module are located in its inner hollow chamber. Said lighting means comprise a plurality of lighting devices (6), means for widening the range of action of the lighting devices (6) and module connection means of the lighting means of each module with the lighting means of at least a contiguous lighting means.
In this second preferred embodiment, as can be seen in Figures 3 and 4, the electrical lighting means comprise at least an electrical connections base part, located in the first body interior (4) and, the plurality of lighting devices (6) are connected to said electrical connections base part.
In this second preferred embodiment, the lighting devices (6) used are LEDs, separately connected to two independent phases A and B, thus increasing the lifetime of said lighting devices (6) and wherein, the base part is formed by an electrical connections board (7), located on the first base (4.1 ) of the first body (4). The plurality of lighting devices (6), as shown in Figure 3, are equidistantly located on all the surface.
Likewise, the lighting modules module connection means comprise in one end of each electrical connections board (7) a male electrical connection plug (8) for connecting to a first connections board (7) of a first adjacent lighting module, and in in another end of each connections board (7), a female electrical connection plug (9) for connecting to a second connections board (7) of a second adjacent lighting module.
In this way, each electrical connections board (7) is connected to at least one electrical connections board (7) of an adjacent lighting module thus forming a series connection of all the electrical connections boards (7).
On another hand, the system connection means are formed by a connection to the electrical grid, located on a first electrical connections board (7) corresponding to the lighting module of the series connection located close to one of the ends of the surface (2) to be cladded and itself, close to the transformer.
Likewise, the last electrical connections board (7) corresponding to the last lighting module of the series connection comprises a closure cap of the female electrical connection plug (9).
In this second preferred embodiment, as can be seen in Figure 2, the means for widening the range of action of the lighting devices (6) are formed by a plurality of semi-spherical protrusions (10) emerging from the second body (5) of the box (3) in opposite direction to the inner hollow chamber. Each of said protrusions (10) is coincidentally located over one of the lighting devices (6) connected to the board (7) respectively.
As shown in Figure 5, the first securing means (1 1 ) of the lighting module to the surface (2) to be cladded is formed by cement, whereas its second securing means (12) to the slab (1 ) are formed by an adhesive, which in this second preferred embodiment is a double-sided tape.
