adversely on the known solutions is that these mostly as a decorative individual object itself inactivated almost by usual To distinguish natural stones or not at all from natural stone, but made of plastic, glass or ceramic. In combination with ordinary Natural stones, e.g. in a bath or on a facade, can this architecturally undesirable be visually perceived as not homogeneous by the viewer. Often there is also a fundamental aversion to the Use of artificial or highly processed materials. In other of the known solutions may - for the priority Lighting purpose to get a meaningful light output - only natural stones up to a certain material thickness used, which then require special support or protective means, what correspondingly expensive is in the production and in the shed is. Or the bulbs must be overcome the absorption capacity stratified natural stones have a disproportionately high luminosity, what about economic and ecological Point of view is disadvantageous. In addition, the are suitable known solutions because of their shape and other properties often even not directly for permanent installation in or on buildings or in outdoor facilities. Here implements the invention.

The object of the invention is therefore to provide a steinmetzmäßig processed and provided for stationary shoring natural stone of commercial format in a simple manner and also after to give an additional, switchable architectural-visual appeal, wherein the natural stone unactivated, especially in combination with other ordinary natural stones should not be recognized by the viewer.

Accordingly, a Natural stone for permanent installation in or on buildings as well in outdoor facilities proposed, consisting of a solid granite body, marble or quartzite, wherein the body obstructs a visible side and a non-viewing side, and in the body at least one, the Nichtsichtseite open recess is provided and with at least one, with a current source connectable light emitting diode, wherein the light emitting diode at least partially disposed in the recess and towards the visible side is aligned.

Natural stones are stone-carved Natural stones, where it is irrelevant, whether craft and / or industrial processing steps were made. The stationary Installation of natural stones in or on buildings and in outdoor facilities includes those known from construction, intended for a long duration and secure mounting options. In particular, the professional installation of floor, wall and ceiling coverings in interior design, of facade elements on buildings as well as path plates and tombs in the outdoor area by setting, Laying, anchoring, grouting and gluing includes. Also the permanent one Installation of a washstand or kitchen worktop followed by grouting falls under it. Essential is the strength and durability of the construction. It is also characteristic that the removal of built-up natural stones from the Installation site for their damage and / or frequently to destruction may lead from adjacent Verbugitteln such as grout.

The Marble, granite and quartzite include both the scientific Nomenclature as well as the recognized commercial language for natural stones.

The Visible side of the installed body is the viewer at usual Liege, sitting or standing position facing or for this then for viewing certainly. On the other hand, the non-sighted side should at least be for the viewer in the usual viewing positions not be seen. The non-sighted side can in particular a to the visible side parallel back of the basic body, but also any other non-viewing page, Border or other surface be.

The Deepening can by usual stonemason processing steps be introduced from a non-viewing side of the body in the body. The recess has a bottom and a preferably circumferential Edge up. The margin can be steep to flat, graded and rounded be. It is essential that the strength of the stone material behind the visible side is weakened relative to the total thickness of the body. The weakening has the function, the way the light of a light source in or through shorten the light-absorbing stone material to reduce transmission losses to keep low. The weakening achieved in particular by material removal is at least so strong that with a given translucency of the Natural stone and usual luminosity of light emitting diodes that of the recess by the stone material Light emitted to the visible side in a dark environment for the human Eye is still noticeable.

A Light emitting diode (LED) is a semi-conductor diode that lights up when current is flowing emitted. There are also organic light emitting diodes available. she consist of a grid of tiny light emitting diodes with organic Semiconductors and are easy to produce on large areas. The least partial arrangement of the light emitting diode in the recess means that components that make up the light-emitting diode, in particular their Connecting pins, from the opening the recess can stand out. An LED directed towards the visible side is with its Main beam direction, i. with the direction of their strongest luminous intensity, in particular vertical, but also oblique oriented to an angle of 45 degrees to the visible surface. It understands itself, that for the operation of the light-emitting diode these over connection lines to be connected to a power source.

The invention has a number of advantages. The natural stone according to the invention provides an on and off again architectural-visual valuable light stimulus that further enhances the exclusivity of the base body used from marble, granite or quartzite. The rock types marble, granite and quartzite are on the one hand ideal as a building material with a variety of applications and on the other hand due to the optical properties of the crystalline material especially for transillumination. The natural stone according to the invention in the off state of the viewer is not to be distinguished from other ordinary Steinmetzerzeugnissen. Due to the degree of opacity of the natural stones used, the inactive LEDs remain hidden from the visible side - the noble surface appearance of the natural stone is not disturbed. In particular, when combined with ordinary natural stones from the same stone type and possibly the same format, a homogeneous overall picture can be achieved. By the rear installation of light-emitting diodes in the main body of the natural stone commercial stone formats can be used or maintained, and also an after stockpiling is easy. Since the Naturvverksteine invention need not be changed in format, especially in their strength, can be dispensed with elaborate support, support or protective means. The already provided, usual space must not be increased or otherwise changed. Light-emitting diodes as lamps are energy-saving, durable, of small size and low-voltage operation also suitable for wet areas. The light emitting diodes are optimally protected in the depression against damage caused by rough working conditions during storage and shoring. In addition, natural stones according to the invention in plate or cuboid shape remain easily stackable, since little or no components protrude from the base body and can damage the visible surface of the neighboring stone. With the exception of the connection to a power source, the construction of the natural stone according to the invention is identical to the construction of other common stonemasonry products.

In a first preferred embodiment the recess is a tapping and / or a groove. For this common Specialization types are the Steinmetz standard tools such as drill bits and milling machine to disposal. The tapping can preferably be introduced by means of a simple bore be substantially cylindrical, non-penetrating hole. The Groove - one elongated, profile-like depression - is preferably of U-shaped Cross-section. But other suitable cross sections are conceivable. In combination can along a groove, for example, several taps in the groove bottom be introduced, the tapping then a greater insertion depth as the groove. The width of the groove can be larger or be smaller than the diameter of the taps. Especially advantageous is in the combination of tapping and groove, that in the groove at the same time Protected connection cables can be moved. Therefor it is often sufficient if the groove is narrower than the tapping.

The Groove can be any longitudinal shape exhibit. In particular, straight, arc, ring, wave or zigzag Grooves for the corresponding arrangement of light-emitting diodes or for the design according to the viewer desired active areas on the visible side of the main body. It is also possible to equip the grooves with branches and also several grooves to connect with branches.

Advantageous it is when the width or the diameter of the recess with the width or the diameter of the light emitting diode corresponds. To introduce the depression only so much material should be removed be inserted that the LED with sufficient arrangement play can be. The main body is not unnecessary weakened and corresponding tool spared. Preferably, the arrangement game so small that the light-emitting diode is introduced into the depression and guided by its edges, preferably pressed can be and frictionally holds in this. It can also be advantageous more arrangement place to arbitrary Aligning the LED and possibly for the introduction of potting compound to disposal to have. It is also conceivable that the LED of a Fastening means, in particular a plastic clip in the recess is held, the recess then corresponding dimensions having.

moreover is advantageous if several recesses are provided in which one or more light-emitting diodes are arranged in each case. In particular arranging groups of LEDs in correspondingly long or wide depressions can achieved in a simple way long or large-sized lighting surfaces become. The introduction of a variety of individual drillings is thereby saved.

In addition, can it may be advantageous to vary the insertion depth of the wells. If the LEDs have different luminosity, can with different insertion depths fluctuations in luminosity be compensated. If the stone inhomogeneous transmission properties this applies accordingly. It can be with a deeper tapping a higher one Transmittance loss in a given area of the body balanced become.

In can advantageously the wells in addition be equipped with light reflectors and / or Lichtstreumittel. This is for example by lining the edges of the recesses with light-reflecting Foil or by arranging others for the LEDs used suitable reflection or light scattering possible.

at disc-shaped primitives the depression usually becomes perpendicular to the back or to the visible surface brought in. In an alternative embodiment, however, it is advantageous the recess in another, especially at a right angle to the visible surface contribute. For example, it is not desirable for treads of steps their tread, but to illuminate their front page. It would be inappropriate the tread over his to pierce the entire depth. Rather, according to the invention in the the tread opposite back of the tread a groove in the immediate vicinity of the front side are introduced.

The light-emitting diodes are with their components preferably arranged substantially completely in the recesses. In this way, the LEDs are permanently protected against external influences. In addition, in particular plate-shaped natural stones remain unrestricted stackable. For in the wells laid connection or connecting lines that applies accordingly.

A A plurality of light-emitting diodes may preferably be provided with a series or Parallel connection can be connected to a power source. suggestions for such Circuits can be made by a person skilled in the art, for example from GB 23 24 901 A receive.

at a further preferred embodiment the natural stone of the invention is the main body executed in two parts, The parts are made of different granite, marble and / or quartzite exist, and wherein the first part is a continuous recess and the second part in the recess of the first part form-fitting and on the visible side flush is fitted, and where either the second part is at least has a depression or the second part is of low thickness as the first part. This embodiment is particularly suitable for disc-shaped Body. From the first part can in particular by means of high-pressure water jet cutting a Recess with any shape to be cut out in the a correspondingly cut second part of another type of stone fit exactly and on the visible side is inserted flush. such Inlays are particularly suitable for exclusive advertising or company logos with a lettering in the style of a blackboard. The blackboard is for example kept in dark marble. In contrast, there is the inserted lettering made of light marble and can be illuminated if necessary.

at a further preferred embodiment of the natural stone according to the invention, has the visible side of the body a rock vein and / or a crystalline inclusion, wherein the depression in or back to the Area of the rock vein and / or to the area of the crystalline inclusion is introduced. In particular, a groove-shaped depression the course one elongated Rock coral follow suit. Suitable for smaller crystalline inclusions preferably tapping. A natural stone with on this Way transilluminated veins and inclusions can create a special ambience create. Combined with a color change circuit and / or time-shifted Switching on and off several LEDs results in additional aesthetic effects.

Of the body of the natural stone according to the invention can be different, for Steinmetzerzeugnisse have typical shapes. A plate-shaped body can in particular a wall, ceiling, floor, step or path covering, a façade element, a window sill, a shower or partition wall, a tile or kitchen counter be. A strip-shaped body In particular, a border, be a pedestal or a step entrance.

Of further can the basic body a particularly sculpturally processed Relief plate with popular motifs such as fruits, vegetables, animals or plants. Also a washstand, a column, a tomb or a monument is possible as a basic body.

Finally, can the natural stone according to the invention in addition to or instead of the predominantly aesthetic function as well Display, advertising, warning or input device may be provided. Especially is a scoreboard, for example, at the entrance of passenger lifts or also in the elevator with the known display elements, such as e.g. one running floor display possible. Of other are natural stones according to the invention For example, as illuminated billboards on house entrances conceivable. Likewise, exclusive escape route displays, coverings on stairs, stair handrails, signposts and hot plates conceivable.

In Connection with a rearward to the visible side of the basic body arranged proximity switch can In a particularly advantageous manner, user inputs are detected. It can magnetic, inductive, capacitive, optical or other proximity switches be used. In this case, the otherwise required switch or Button identification also by a display device according to the invention replaced or supplemented become.

The backside 3a has the center of the opening of a depression in the form of a bore 20 as well as the groove-shaped duct 40 with a U-shaped cross section. The duct 40 extends from the tapping 20 to the right narrow side 3b of the basic body 1 , The duct 40 is narrower than the diameter of the tapping 20 , On the right narrow side 3b of the basic body 1 protrude from the duct 40 the two electrical connection lines 50 and 51 out. In the opening of the tapping 20 are still the ends of two connection pins 32 and 33 to recognize a light emitting diode.

In 3 is the natural stone according to 1 and 2 finally in cross-section centered along the duct 40 and in the middle through the tapping 20 shown. The tapping 20 is in the direction of the visible surface 2 of the basic body 1 introduced and has a depth of about two thirds of the strength of the body 1 , The duct 40 is about a quarter as deep as the tapping 20 , In the tapping 20 is a commercially available, typically constructed light-emitting diode 30 with a luminous body 31 and the two connection pins 32 and 33 arranged. The tapping 20 is slightly larger in diameter than the filament 31 , The luminous body 31 shows with his, by an arrow 35 characterized main beam direction perpendicular to the visible surface 2 , To power the LED 30 are their two connection pins 32 and 33 in the simplest way with the two electrical connection lines 50 and 51 Lines, of which in cross section of 3 only one is shown, connected by solder points. The electrical connection cables 50 and 51 are in the duct 40 guided along and leave the main body 1 on the right narrow side 3b , At the free ends of the electrical connection lines 50 and 51 is outside the main body 1 for operation of the LED 30 a power source, not shown, connected. The light-emitting diode 30 and the electrical connection cables 50 and 51 can in the simplest way with a not shown, on the back 3a over the tapping 20 and the duct 40 applied adhesive tape secured against falling out and protected against contamination from the outside. The backside 3a of the basic body 1 Can be used directly for installation as an adhesive surface for a tile adhesive.

In the 4 to 13 are cross sections of various inventive natural stones only shown in principle. Their basic body 1 Marble, granite or quartzite therefore usually have other formats or dimensions and in particular have different proportions to the remaining elements. On the representation of connecting cable, with which the respective light-emitting diodes are connected to a power source, has been omitted. With the exception of 10 and 12 show the main beam direction of the respective LEDs in the cross sections down, but always to the visible surface 2 the respective basic body 1 , The different depressions are always introduced from a non-visible side.

The two basic bodies 1a and 1b have the same format and together form a two-layered structure. In the right, first basic body 1a are at the back or non-sight side 3a two depressions 25a and 25b provided in each of which a separately or together with a power source connectable light emitting diode 30a and 30b is arranged. The light-emitting diodes 30a and 30b are to the front or visible side 2a of the first basic body 1a aligned. At the back 3a of the first basic body 1a is the second basic body 1b , which has no depressions and light-emitting diodes and serves only as a diaphragm arranged. The two-layer structure may be in a larger format with correspondingly more light-emitting diodes, for example, a one-sided illuminated shower screen or other partition wall made of marble, which should be considered on both sides. It is also possible to produce a two-sided luminous wall in that the second base body is mirror-inverted to the first one, ie also has recesses with light-emitting diodes and is back to back to the first base body, wherein the recesses do not necessarily have to be opposite.

21 shows a cross section through a natural stone according to the invention as a washstand for a bathroom. The washbasin consists of a plate-shaped first base body 1a and from a bowl-shaped second base body arranged below the first one 1b , Both basic body 1a and 1b have a corresponding round in plan view opening. The bowl-shaped body 1b has at the bottom in the middle an outflow opening 9 , The top of the plate-shaped and the inside of the bowl-shaped body are visible sides 2a and 2 B , On the bottom 3a the plate-shaped and on the outside 3b of the bowl-shaped body are each several wells 20 brought in. Not shown is that in the wells 20 in each case at least one light-emitting diode which can be connected to a current source is arranged.

Finally shows 22 a natural stone according to the invention with a base body 1 in the form of a border. At the back 3 of the basic body 1 are comparable to 1 , five bores introduced and with a less deep duct 40 connected with each other. It can also be seen that five light-emitting diodes shown only schematically 30 in the taps 20 are arranged and in the direction of the curved visible surface 2 demonstrate. The LEDs are connected to the connecting cables 50 and 51 connected in series and connectable to a power source.
