Figures I IA and I IB show two typical embodiments of lighting devices.

In the figures IA, IB and IC three typical embodiments of rotating facade elements according to the invention are shown schematically in side view, which differ from each other in the number of lighting devices contained therein.

FIG. 1A schematically shows a side view of the simplest embodiment of a rotatable facade element according to the invention. The two bearing elements 1, of which only one is shown, consist of a hub part 2, from which a first connecting arm Ib goes out, at the outer end of which a louver part 4 is attached via a substructure element 5. From the hub part 2, a further connecting arm Ia also goes out, which carries at its end a lighting device 3, advantageously a transparent tube, in which spaced light units are arranged, which constitute separately controllable light pixels. However, the lighting device 3 may also be any other lighting device such as a fluorescent tube, a light string, etc., act. The axes of the first connecting arm Ib and the further connecting arm Ia together form an angle α, which may be in the range of 45 to 180 ° and is preferably about 120 °. This facade element is rotatable about a central axis extending through the hub part 2. If it is assumed that the facade outside is on the right side of Figure IA, is therefore in the illustrated rotational angular position of the

Lamellar part 4 on the facade outside and can serve as a shading element similar to a Venetian blind. If there is a photovoltaic element on the fin part 4, thus not only an adjustable shading achieved, but also electricity can be generated.

In the illustrated rotational angle position, the lighting device 3 is inward. By turning, preferably in a clockwise direction, about the axis passing through the hub part, for example by about 180 °, the lighting device 3 can be brought to the facade outside and can, in combination with several or a plurality of other facade elements, which are arranged in parallel one above the other, be used for lighting purposes or display or display purposes.

Figure IB shows another typical inventive facade element, also in a schematic side view, wherein on the hub part 2 in turn a first connecting arm Ib is provided, which carries at its end via a substructure element 5, a fin part 4, which may be formed as well as above to figure IA was explained. At the hub part 2, two further connecting arms Ia are mounted in this case, each carrying at its end a lighting device 3, which may be formed as described above for Figure IA. The two further connecting arms Ia are shown in FIG. 1B with the same length. However, they can also have different lengths. The angle α ¹ between the axis of the first link Ib and the axis of one of the two further connecting arms Ia is in the range of 60 to 120 ° and is preferably 60 to 90 ° and particularly preferably about 80 °.

The angle β between the axes of the two further connecting arms Ia is in the range of 60 to 120 ° and preferably in the range of 90 to 120 ° and is particularly preferably about 100 °, wherein the sum α ¹ + β is preferably equal to 180 °. If, in turn, it is assumed that the outside of the façade is located on the right side of the drawing, the position and effect of the lamella part 4 are the same as those mentioned above for FIG. In the illustrated rotational angle position, the two light sources 3 supported by the further connecting arms Ia lie on the inside of the façade.

After turning, preferably in turn clockwise, for example, about 180 °, the two lighting devices 3 are on the outside of the facade and preferably perpendicular to each other in a vertical plane. If several or many such facade elements are arranged one above the other in an arrangement horizontally and parallel to one another and, if appropriate, several such arrangements are provided next to one another, arbitrarily large-area lighting surfaces or display or display surfaces result, with which even video images can be displayed.

Figure IC finally shows the third basic embodiment of the facade element according to the invention in a schematic side view, again only one of the bearing elements 1 is shown. From the hub part 2, the first connection arm Ib goes out, which, in turn, carries the lamellar part 4 via a substructure element 5. From the hub part 2, in the case of FIG. 1C, three further connecting arms 1a run out, each of which holds a lighting device 3 at its end. In order to achieve a luminous surface or a flat display in an arrangement of several such facade elements, it is

in this case, it is necessary for the three lighting devices 3, when located on the outside of the façade, to again lie in one plane, preferably in a vertical plane.

Although in FIG. 1C the lighting devices 3 lie on the inside of the facade, this center plane 12, which runs through the center lines of the lighting elements 3, is represented by a dashed line. This situation can be achieved by suitable choice of the lengths of the further connecting arms Ia as a function of the prevailing angles βi and β ₂ . The angle α "between the axis of the first link arm Ib and the axis of an outer one of the three further link arms Ia is in the range of 60 to 120 ° and is preferably about 120 °. The angles βi and β ₂ , which may be the same or different, are in the range of 30 to 60 ° and are preferably about 50 °, wherein the sum ßi + ß _{2 is} preferably about 120 °.

In the case of the embodiment of FIG. 1C, each individual facade element provides three lighting devices 3. If the facade element of Figure IC is rotated by about 180 °, preferably in a clockwise direction, reach the three luminescent devices 3 on the outside facade and are then in lighting or display position, the center plane 12 is preferably perpendicular. By turning back e.g. counterclockwise, the fin part 4 can be brought back to the facade outside and can then serve as a shading element or in combination with photovoltaic elements as a power generator.

FIG. 2 shows a perspective view of a façade element arrangement according to the invention with several rotatable facade elements, which are shown in posts 6a, one of which is stored and horizontally arranged in parallel one above the other. In Figure 2, the preferred embodiment according to the invention is shown, in which the bearing element 1 carries two further connecting arms Ia, each carrying a lighting device 3. The first connecting arm Ib carries as a plate part a support plate 4a, on which one or more photovoltaic elements 4b are arranged, which serve to generate electricity. In Figure 2, the sun is illustrated by the schematic sun and the three arrows. The façade elements are therefore in a shading position in which electricity can be generated at the same time. The support plate 4a is supported by a substructure element 5 on each side. The lighting devices 3 have spaced light units 10, which advantageously consist of light emitting diodes, with which after the RGB system in addition to white and colors can be displayed.

If the facade elements are rotated in the present case clockwise about the axis of rotation passing through the hub part 2, for example by about 180 °, the two lighting devices 3 of each facade element lie on the outside of the façade and preferably in one plane and can serve for lighting and display purposes.

The dimensions of the fin part 4, and thus also the length of the lighting devices 3, are basically not limited, as long as no stability or strength problems occur. The length of the fin part 4 or the support plate 4a for photovoltaic elements is favorably in the range of 50 to 180 cm and is usually about 1 m; the width is advantageously in the range of 5 to 30 cm. The length of the lighting devices 3 depends on the length of the fin part 4, or vice versa.

The lighting devices 3 with luminous units consisting of light emitting diodes 10 are available as such in the trade; the length of the fin part 4 is adjusted in this case according to the length of the lighting device. The length of the connecting arms Ib, measured from the center of the hub part 2 to the substructure element 5, is in the range of 50 to 250 mm, and is preferably about 50 mm.

The length of the further connecting arms Ia, measured from the center of the hub part 2 to the center of the lighting device 3, is in the range of 50 to 250 mm and is preferably about 50 mm.

In Figures 3 A, 3B and 3 C, the same facade elements as in the figures IA, IB and IC are shown, wherein like parts are designated by like reference numerals. In the embodiments shown in Figures 3A to 3C, the bearing elements 1 correspond to an advantageous execution in the form of hollow profiles, wherein the connecting arms Ia and Ib starting from the hub part 2 outwardly taper slightly and advantageously are formed approximately frusto-conical. In the cases of FIGS. 3 A, 3 B and 3 C, the substructure element 5 has a connection sleeve for connection to the end of the correspondingly designed first connection arm Ib, which advantageously has a through bore through which the connection lines of the photovoltaic elements 4 b lead to the hub part 2 can be. The connecting sleeve has two extending in opposite directions, strip-like projecting bracket elements whose center plane is preferably perpendicular to the median plane of the fin part 4 or the support plate 4a and parallel to their narrow sides. At the ends of the bracket elements are support members for supporting the fin part. 4

or the support plate 4a provided with the photovoltaic elements.

As in the case of FIGS. 1A to 1C, FIGS. 3A to 3C also show the three typical embodiments of façade elements according to the invention, the façade element of FIG. 3A being another Connecting arm Ia has on each bearing element 1 and consequently carries a single light emitting device 3, while the embodiment of Figure 3B has two further connecting arms Ia in each bearing element. In the embodiment of FIG. 3C, each bearing element 1 carries three further connecting arms 1a, each of which supports a lighting device 3. Due to the advantageous embodiment of the bearing elements 1 as hollow sections with inner connection to the hub part, it is possible in a particularly advantageous manner, the wiring of the lighting devices 3 by a further connecting arm Ia to the hub part 2 and the connecting lines of the photovoltaic elements 4b through the first connecting arm Ib also therethrough to the hub part 2 to drive, from which the corresponding connection lines are then guided, for example, in a serving for holding post 6a, which is indicated schematically in Figure 2.

For the adjustment of the various functional rotational angle positions of the facade elements of Figures 3 A to 3 C, the same applies what was done above to the facade elements of Figures IA to IC.

Figure 4 shows an enlarged side view of a facade element according to the invention with two further connecting arms Ia per bearing element 1, as shown schematically in Figures IB and 2 and in Figure 3B, wherein the hub part 2 and the lighting devices 3 are shown schematically in cross section.

As already explained with reference to FIG. 3B, this advantageous embodiment of the facade element according to the invention has bearing elements 1 which each have a first connecting arm Ib and two further connecting arms Ia. The first connecting arm Ib carries a substructure element 5, which has a connecting sleeve 5e for connection to the end of the first connecting arm Ib; this connecting sleeve is advantageously provided with a through-hole, through which the wiring 7b of the photovoltaic elements 4b can be guided to the hub part 2, since the connecting arms 1a and 1b, as explained above for FIGS. 3A to 3C, are advantageously designed as hollow profiles. The substructure element 5 has two of the connecting sleeve 5e in opposite directions extending strip-like Konsolelemente 5a, 5b, the median plane is preferably perpendicular to the median plane 13 of the fin part 4 or the support plate 4a and preferably parallel to the narrow sides of the fin part 4 or the support plate 4a and on whose ends support elements 5 c, 5 d are provided for supporting the fin part 4 or the support plate 4 a, whose axes are aligned parallel to each other and preferably also to the axis of the connecting sleeve 5 e. The support members 5 c, 5 d are advantageously designed as screws and / or nuts to allow easy replacement of support plates 4 a. At the two other connecting arms Ia lighting devices 3 are supported, which, as is schematically indicated, light units 10, which advantageously consist of light emitting diodes and each represent a light pixel. The wiring 7a of the lighting devices 3 is guided by the connecting arms 1a executed as hollow profiles to the hub part 2 and can be guided from there via a corresponding storage, for example in posts 6a, as indicated in Figure 2, to corresponding control circuits.

By guiding the cabling 7a, 7b inside the bearing elements 1, a good protection of the lines against atmospheric influences is achieved, wherein the respective Kabeleinfuhrungen at the ends of the connecting arms Ia, Ib can advantageously also be sealed in a suitable manner, for example with silicone gaskets , Cable glands and the like.

In the embodiment shown in Figure 4, which represents a particularly advantageous construction, the angle α ¹ between the axis of the first connecting arm Ib and the axis of the adjacent further connecting arm Ia is 80 °, while the angle ß between the two other connecting arms Ia 100 ° is. The orientation of the light-emitting diodes 10 in the transparent tubes 8a, for example, on Circuit boards are 9, is such that in the position of the facade element in which the lighting devices 3 are exactly above each other in a vertical plane, maximum radiation occurs. This means that the circuit boards 9 of the lighting units 10 are advantageously aligned in the lighting devices 3 so that they are perpendicular, when the two lighting devices are arranged vertically one above the other.

The facade elements according to the invention are turned back and forth between two maximum end positions. This means that the introduced into the hub part 2 lines of cabling 7a, 7b, which are continued from there on the storage in support, such as the posts 6a, only a maximum of about 180 ° back and forth rotated, which is no electrical or mechanical problems. Consequently, in order to reach the previous end position again, the facade element is not further rotated in the same direction, but turned back.

This can not lead to unwanted twisting of cables.

Figures 5 A, 5B and 5C show schematically in side view each a facade element arrangement according to the invention with parallel superposed facade elements, three of which are shown. Also in this case, the facade exterior is on the right side of the drawings. In the rotational position of Figure 5A, the lighting devices 3 are all facade elements on the outside facade exactly above the other, the distances between two lighting devices 3 of a facade element advantageously equal to the distances of the mutually adjacent lighting devices 3 of adjacent facade elements. The facade elements form in the rotational position of Figure 5 A, a matrix that can be used for lighting and display purposes.

The rotational position of the façade elements shown in FIG. 5B is such that the lamella parts 4, which carry, for example, photovoltaic elements 4b, are aligned perpendicular and flush to the façade outer side and the Facade so close to the intervening column, almost completely. In this angular position, the facade elements can act as a so-called double façade.

According to a preferred embodiment, the surface of the photovoltaic elements 4b is smaller than the surface of the fin part 4 or the support plate 4a and is advantageously designed so that around the or the photovoltaic elements 4b around a peripheral edge remains free, in a fin part 4 or a Support plate 4a made of glass thus represents a translucent area. Even in the case of the completely closed facade element arrangement illustrated in FIG. 5B, in this embodiment daylight can be incident on the building located behind it.

Finally, FIG. 5C shows one of the tag positions ^{1 of} the facade elements in which the lamella parts 4 with the photovoltaic elements 4b are located on the outside of the façade and in a position aligned with the direction of the sun's rays, which is indicated by the schematized sun and the arrows in the figure. The schematic eye is intended to indicate that in these rotational angle positions, a more or less free view from a building behind it is possible outside.

Due to the rotatability of the facade elements, the photovoltaic elements 4b, for example, by automatic Nachfuhrung depending on the position of the sun and / or depending on the latitude, each optimally aligned to the sun, to maximize the efficiency of the photovoltaic elements and maximize the current efficiency ,

In addition to the rotational positions shown in FIGS. 5 A, 5 B and 5 C, a further typical rotational angle position is possible, in which the lamellar part 4 or the carrier plate 4 a, which optionally carries photovoltaic elements 4 b, is in an approximately horizontal position, wherein the hub part 2 above the fin part 4 or the support plate 4a is located. In This position is consequently the underside of the fin part 4 or the support plate 4 a with the substructure element 5 swept upwards. The underside of the lamella part 4 or the support plate 4a and possibly also the underside of the substructure element 5 can, although this rotation angle position variant provided

is so surface-treated or surface-coated that optical properties such as reflection or selective absorption of light radiation are achieved.

In Figure 6 four facade elements according to the invention are partially shown in the area in which they are rotatably mounted on a serving as a support post 6a. Figure 6 shows the facade element arrangement in a partial view from the front, wherein the facade elements are in a rotational angle position which corresponds approximately to the position of Figure 5A, so the lighting or display position.

The storage of the facade elements in the post 6a can be done, for example, that on the bearing elements in the axial direction outwardly bearing journals are provided, which are accommodated in a corresponding bearing on the post 6a. In or on the post 6a facilities for rotating the facade elements are also provided (not shown), with which all facade elements can be brought into the same rotational position. Such drives and their control are familiar to those skilled in the art.

The cabling 7b of the photovoltaic elements 4b on the carrier plates 4a is guided through the hub part 2 into the carrier 6a, in which the cabling 7 is then continued to corresponding control devices.

In the lighting devices 3, the lighting units 10, which are spaced from each other, shown schematically by circles. The light units are advantageously light emitting diode arrangements, the allow a representation of colors as well as white on the RGB system.

The dashed circle in Figure 6 illustrates such a light-emitting diode cluster, which is shown with more details in Figures 7 A to 7D. FIG. 7A shows a lighting unit comprising four light-emitting diodes 11, while in the arrangement of FIG. 7B five light-emitting diodes 11 form a diode cluster corresponding to a light-emitting pixel. In FIG. 7C, the five light-emitting diodes are not linear, but arranged in a square structure, resulting in a point-shaped light-emitting pixel. Finally, Fig. 7D shows an arrangement of three light emitting diodes, e.g. a red (R), a green (G) and a blue (B) radiates. The control of such LEDs for display purposes is familiar to the expert; corresponding drive circuits and controllers are commercially available.

Figure 8 shows the illustrated in Figure 6, serving as a carrier for the facade element assembly post 6a in horizontal section. The post 6a is connected to horizontally arranged connecting bars 6b, which are shown in fragmentary form, wherein the posts 6a and the horizontally arranged connecting bars 6b form a frame 6, as shown in FIG. In Figure 8, two bearings for facade elements are schematically indicated by dashed lines in the narrower part of the post 6a.

With the help of the post 6a, between which the facade elements according to the invention can be arranged one above the other and parallel to each other horizontally, optionally using the connecting bar 6b, facade element arrangements can be constructed with which large-scale displays or large-scale lighting walls can be generated. FIGS. 10A and 10B show a perspective view of three superimposed objects Facade elements according to the invention as a section of a facade element arrangement according to the invention.

In the perspective views of FIGS. 10A and 10B, the outside of the façade faces the observer. FIG. 10A shows the rotational position of the facade elements in which the lamella parts 4 or the carrier plates 4a, which carry photovoltaic elements 4b and are attached to the connection arms 1b, are in a sun-oriented position, so that incident solar radiation can be utilized maximally for power generation. The facade elements have a journal Ic which extends from the hub part 2 to the outside and serves for the storage of the facade elements, for example in posts 6a, as shown in Figures 6 and 8. The axis a-a of the facade elements passes through the centers of the two bearing pins accordingly.

The cabling 7a and 7b of lighting devices 3 and photovoltaic elements 4b advantageously extend through the interior of the bearing journal Ic. At the journal Ic or at another location on the outside of the bearing elements 1, the drive mechanisms for rotation of the facade elements may be provided.

The attached to the connecting arms Ia lighting devices 3 are facing in this rotational position of the facade inside. In the rotational angle position shown in FIG. 10A, the carrier plates 4a with the photovoltaic elements simultaneously serve as shading elements. It is of course also possible that the facade elements exclusively have lamella parts 4, without photovoltaic elements are provided. However, it corresponds to an advantageous embodiment of

Façade elements according to the invention to combine the shading effect with a power generation. In FIG. 10B the façade elements are shown outside the façade in the rotational position, in which the lighting devices 3 are located exactly vertically one above the other, ie lie in a vertical plane and can form a lighting or display matrix with their lighting units 10. The bearing elements 1 carry, as has already been described in detail above, again the further connecting arms 1a with the lighting devices 3.

Depending on the embodiment of the lighting devices 3, which may have, for example, flat cable connections, corresponding electrical connections are provided, for example watertight plug-in connections, which enable easy replacement of lighting devices 3.

The support plate 4a with the photovoltaic elements 4b is facing in this position of the facade inside. In FIG. 10B, the substructure elements with the connecting sleeve 5e and the console elements 5a and 5b can be seen on the underside of the carrier plate 4a. The facade elements are mounted with their journals Ic, through which the wiring 7, which includes the wiring 7a and 7b, performed. Also in Figure 1OB the direction of the axis of rotation a-a is indicated, which runs through the bearing journal Ic. To return from the rotational angular position of FIG. 10B back to the position of FIG. 10A, the facade elements are rotated counterclockwise from the position of FIG. 10B; To return from the position of Figure 10A to the position of Figure 1OB, the facade elements, in the present perspective view, rotated clockwise to the right.

In FIGS. 1A and 1B, two typical embodiments of lighting devices 3 are shown. FIG. 11A shows a tube 8a in which luminous units constructed from light-emitting diodes 11 are provided. The Luminous units 10, which are spaced apart from one another, as can be seen from FIG. 6, form luminous pixels, from which, as described above, large-area matrix displays can be combined. The wiring of the corresponding light-emitting diode cluster runs in the tube 8a.

The tubes 8a are made of a transparent material. A particularly good transparent material with high durability is glass, but tubes 8a made of a plastic material such as acrylic glass (Plexiglas ^® ) are more advantageous for weight reasons.

The electrical leads which connect the individual lighting units 3 to each other extend within the tubes 8a and are led out at the ends, for example laterally, so that the ends of the tubes 8a can be sealed.

The tubes 8a are mounted at the ends of the connecting arms 1a in suitable brackets, for example in snap elements or spring clips, which allow easy replacement of the lighting devices 3.

In Figure 1 IB another embodiment of a lighting device 3 is shown, which is also known per se. In this luminous device 3, the light-emitting diodes 11 constructed light units 10, which are arranged spaced from each other, in a substantially U-shaped profile, wherein the light-emitting diodes including their wiring waterproof

are potted and protrude from the potting compound. For the electrical connections at the ends of these elongated lighting devices, the statements made for the tubes 8a apply.

The facade elements according to the invention may have lighting devices 3 of both types, since with two above-mentioned types of Lighting devices can in principle achieve similar matrix arrangements of light pixels.

In summary, the present invention provides novel rotatable facade elements, which can be combined into large facade element arrangements, which in turn can be used to realize large-area light fields or large-area display devices, such as video walls. By simply rotating about the longitudinal axis of the facade elements can be switched between a lighting or display function on the one hand and a shading function or photovoltaic power generation function on the other hand, resulting in completely new ways of functional facade design.
