    Illuminated facade panel
    The present invention relates to an illuminable facade panel with at least one light source integrated in the facade panel, preferably in the form of a row-shaped LED arrangement, the light of which is preferably uniformly radiant from a panel front side.
    In order to better use building facades for the presentation of advertising or general information or to illuminate for emphasis or for aesthetic reasons, colored or otherwise, intentional facade panels are used in recent times, in the manner of a front facade before actual façade structure hung or otherwise secured and can be lit by light sources. Such facade panels may comprise a transparent light panel such as a glass plate, in the laterally from the edge via there arranged light sources, for example in the form of LEDs light is coupled, which is made uniform over the main surface of the glass plate, see. For example, the document DE 10 2008 016 737 A1 or DE 100 41 850 A1. Such facade panels with illuminable glass plates as a luminous surface have the advantage that they are transparent when used as intent facade at least in the off state during the day, so that the facade panels can be dazzled even in front of windows or balconies or loggias and the occupants or users still see through and the Environment.
    In principle, such illuminable facade panels can also be used in courtyards or interiors, for example as a ceiling panel and / or wall panel, to create luminous interior surfaces and to set appropriate architectural accents. In particular, however, such facade panels are used on exterior facades to see the lighting effect of the facade panels of public spaces such as streets and squares or perceive information represented hereby. 2/22 2
    Depending on the size of the façade, special effects or also information presentation can be achieved by assembling the intentional façade from a multiplicity of façade panels which can be illuminated in different colors, so that, for example, diamond patterns, stripe patterns or also more complex symbols can be represented. For example, if façade panels with a size of, for example, 1 m × 1 m are combined to form a front façade, the individual façade panels act like pixels at least from a distance, so that even more complex representations can be realized, at least for larger facades. Depending on the design, the facade panels can also be dimensioned significantly larger, for example, several meters to several meters, or cover larger pieces of surface as stated above
    In order to display in the manner of a pixel image writing, images or even "moving" images in the form of films or television pictures even on smaller buildings or to be armed at shorter viewing distances, so-called media facades have already been proposed, which essentially consist of a Matrix-like arrangement of sources of light sources, in particular LEDs, which are mounted on a carrier material such as a curtain net or a carrier panel and can be controlled individually or in groups via a suitable image control to use in the manner of an oversized screen a building facade for displaying information and images , Such media facades show, for example, the publications DE 10 2006 037 878, in which LEDs are fastened to the warp and weft threads of a wire mesh, or DE 10 2005 028 655 A1, which provides obliquely downwardly directed blind slats, which are erected by a person standing on the street Image projector are irradiated and serve as a canvas, so to speak. In such media facades, however, has so far been disadvantageous that a greater part of the emitted light is thrown into the upper half-space and thus "dirty" the night sky and leads to an ineffective use of light. On the other hand, such media facades are no longer transparent, so that lying behind a corresponding intent facade windows or balconies are no longer usable or no longer allow view of the surroundings, even if the media facades are not used during the day. On the other hand, when the media façade 3/22 is turned on, 3 rooms or windows lying behind it are unintentionally illuminated and persons located in such rooms are dazzled. The brightening of the background or the piece of façade behind it makes the media façade itself pale and reduces its luminosity and contrast. On the other hand, projection solutions with image projectors spaced from the façade on forecourts or roads in confined spaces are impractical or, depending on use, for example, not possible as a road traffic surface.
    The present invention is therefore an object of the invention to provide an improved illuminable facade panel of the type mentioned, which avoids the disadvantages of the prior art and the latter further develops in an advantageous manner. In particular, a high luminosity is to be achieved on the facade panels with high lighting efficiency, without affecting the usability of located behind the facade panels rooms like Baikon or rooms with the facade panels going windows by unwanted brightening or even glare and the view through the facade panels to affect the landscape too much.
    According to the invention, the object is achieved by an illuminable facade panel according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.
    It is therefore proposed to construct the luminous surface of the panel of elongated Lichtum-lenkpaneelen, which are spaced sufficiently far apart in approximately parallel arrangement to look good from behind lying behind the facade panel spaces, and on the other hand by at least one integrated into the panel itself Light source to provide a grinding radiation at a very acute angle to the main panel formed by the Lichtumlenkprofilen panel in which the light emitted from the light source is substantially completely directed to the Lichtumlenkprofile and radiated from them substantially completely to the panel front side. Due to the abrasive or acute-angled irradiation by means provided at the edge of the panel light deflecting profiles despite their relatively large spacing can completely capture the abgege-4/22 4 bene light and redirect in the desired direction, so that high luminous efficiency of the Panels without dazzling effect can be achieved. According to the invention form a plurality of elongated Lichtumlenkprofile in approximately parallel arrangement to each other together the luminous panel main surface and are spaced apart from each other such that the Fassadenpaneel viewed from a panel back is transparent, the at least one light source laterally disposed on the edge of the panel main surface and with a Deflection optics is provided such that the light of the at least one light source is dragged at an acute angle to the said panel main surface from the front of the panel substantially completely on the plurality of spaced Lichtumlenkprofile, of which the light is radiated substantially completely to the panel front side. Due to the abrasive irradiation, the light deflection profiles appear as a closed surface towards the light source, which completely captures the emitted light. The facade panel is irradiated from the front of the panel, towards the panel also emits the light again, which is deflected by a deflection optics, the light of the laterally placed light source substantially completely on the plurality of spaced deflection profiles, so that despite spacing the deflection profiles no light penetrates to the panel back. With high transparency of the facade panel unwanted illumination to the panel rear side or even glare can be avoided and at the same time a high luminosity of the facade panel can be achieved.
    The Lichtumlenkprofile can this case in a further development of the invention over its length substantially constant cross-section, which advantageously contoured in the manner of a polygonal profile, in particular may be triangular. With the help of such in cross-section triangular Lichtumlenkprofile on the one hand unwanted brightening of the back of the façade panel or the underlying facade when irradiated by the at least one artificial light source can be avoided while reversed daylight passed through the facade panel or can be introduced in lying behind the facade panel rooms , In particular, such triangular contoured Lichtumlenkprofile be aligned with one of its legs substantially parallel to the underlying 5/22 5 facade surface or parallel to the panel main surface, while another leg surface of the edge of the integrated light source is facing such that the light coming from there is emitted in the desired manner to the panel front side. The third side or the third leg of the Lichtumlenkprofile may be facing away from said integrated artificial light source and / or a panel front, in particular facing towards the sky upper half space to initiate daylight, said third profile surface curved, preferably concave and / or channel-shaped can be contoured. The leg surfaces of the triangular Lichtumlenklamellen facing in the panel integrated artificial light source can be aligned obliquely down to the panel front side at least approximately vertical arrangement of the facade panels to the light coming from the integrated light source down to a street or a square in front of the facade to radiate, and / or at least approximately form a flat deflection.
    In particular, the facade panel may be designed as a whole or may have a straight longitudinal axis and / or jointly define a flat panel main surface, so that the facade panel can be mounted approximately parallel in front of a flat building facade, or alternative use if necessary . also lying on a ceiling or upright in front of an inner wall can be attached. However, an e-bene design of Fassadenpaneels is not mandatory. For example, in order to be able to be mounted accurately on rounded facades such as in circular cylindrical skyscrapers or towers, the facade panel can also be channel-shaped or cup-shaped curved, in which case the Lichtumlenkprofile may have a correspondingly curved trained longitudinal axis. As an alternative or in addition to such a curvature, depending on the shape of the façade, other contour adjustments may be provided, for example, in the form of a bent-type construction and correspondingly shaped light-deflecting profiles with a bent longitudinal axis course. 6/22 6
    Advantageously, the at least one light source, which may be in the form of a row-like point light source arrangement, for example in the form of an LED row, approximately in the plane defined by the Lichtumlenkprofilen -bzw. in the case of curvatures or kinked contours in the aforementioned sense - approximately arranged in the enveloping surface defined by Lichtumlenkprofilen, but slightly offset from this plane or surface out, so that the light sources or their associated deflection optics, the light at a very acute angle grinding on the main panel surface or the light-umlenklamellen forming this main surface can be. In particular, the at least one light source can be only slightly spaced from the main panel surface formed by the light deflection profiles such that a main radiation direction of the light radiation emitted by the light sources or the deflection optics to the said panel main plane or main surface is at an angle in the range of 1 ° to 15 °, preferably about 5 ° to 10 ° occupies.
    When erecting the facade panels, for example, in front of a building-de-outer facade, the light sources are advantageously arranged at a lower edge region of the panels, so that each panel can be irradiated from its lower edge. If several facade panels are arranged one above the other, each façade panel can be separated from "its", i. At the lower edge region of the respective facade panel arranged light source are irradiated.
    The Lichtumlenklamellen or their light source facing leg surfaces are advantageously arranged and contoured that the light thrown onto them obliquely down to the panel front side is emitted, wherein the radiated from the Lichtumlenklamellen light can have a main radiation direction, which at an acute angle to the panel main surface , which is formed by the Lichtumlenklamellen occupies, for example in the range of 10 ° to 30 °, wherein the light emitted by the lamellae - when viewed in the longitudinal direction of Lichtumlenkprofile - can experience an expansion of only 10 ° to 30 °, ie It is advantageously radiated only a very narrow beam down to the street or the square in front of the building facade. 7/22 7
    The deflecting optics, which is associated with the at least one light source of a respective facade panel, may in principle be designed differently, for example comprising a lens and / or a reflector, in order to direct the light emitted by the light source selectively and completely only to the light deflecting profiles of the facade panel. The deflection optics is such that no light is misdirected past the light deflection profiles into the sky, onto the facade behind the panel, or in other directions. If several point-shaped light sources are provided, for example, in series, each light source can be assigned its own deflection optics in the form of a lens and / or a reflector, such a lens noting, in particular, the primary lens normally associated with a LED, but a dedicated, downstream secondary lens. The lens and / or the reflector are advantageously designed such that they completely capture the light emitted by the light source and are substantially completely on the panel main surface formed by the Lichtumlenklamellen.
    In particular, the said deflection optics can be such that, instead of a rotationally symmetrical or orange-cut light cone of the light intensity distribution of the punctiform light source is given a particular oblique, pyramidal asymmetry to illuminate a rectangular facade piece as evenly as possible on the facade. By providing a plurality of light sources, these can thereby complement one another much better, since the rectangularly lit pieces of surface illuminated on the panel light surface, which are formed by the light deflection slats, can be juxtaposed or uniformly superimposed. The light redirecting optics may each have a lens and / or a reflector for each punctiform light source, which substantially completely captures the light of the associated light source and casts it on an approximately rectangular panel main surface formed in common by the plurality of parallel light redirecting profiles. The lenses and / or reflectors are each contoured such that the light captured by the associated light source not only in a circular or round, for example elliptical or Schiefrunden, light cone, but, for example in oblique employment of the light source to the panel main surface, in a preferably, the light pyramid can be transformed, ie The bundle of rays emanating from the light-deflecting optics of a light source, viewed in its entirety, has an approximately rectangular cross section, so that the illuminated facade panel piece is likewise rectangular. In this way, a high homogenization of the luminous panel surface can be achieved, which in turn can be achieved a total uniformly illuminable facade.
    In a further development of the invention, the at least one light source can be arranged on a panel front side, so that the light deflection profiles are irradiated from a panel front side and also radiate the light back to the panel front side. In particular, the at least one light source can in this case be arranged very close to the panel main surface formed by the light deflection profiles, in particular at a lower edge of the respective facade panel in order to irradiate the Lichtumlenklamellen from below at a very acute angle to the panel main surface, so that the Lichtumlenkprofile the light then can radiate back to the front of the panel and / or down.
    In order to protect and block off the light sources in such a front light source arrangement, the respective light source can advantageously be sunk in a frame profile which encloses the panel main surface formed by the light deflection profiles.
    Due to the abrasive or very acute-angled irradiation of the main panel surface or the light deflection profiles forming this main surface, said light deflection profiles can be spaced relatively far apart, whereby high transparency in the sense of an unobstructed view through the facade panel can be achieved. In a further development of the invention when viewing the facade panel in a viewing direction perpendicular to the panel main surface - ie substantially perpendicular to the building facade - a ratio of transparent recesses or the surface of the recesses between the Lichtumlenkprofilen to the blocked by the Lichtumlenkprofile panel surface be greater than 1, preferably in the range of about 10: 1 to 2: 1, in particular about 5: 1 to 3: 1, ie the area transparent to the Fassa-9/22 9 denpaneel when viewed from the vertical direction can be approximately four times the area obstructed by the light deflection profiles.
    In a further development of the invention, the above-mentioned preferably in cross section triangular Lichtumlenkprofile can be flattened in cross section or have a flattened, triangular cross-section, in which the facade facing legs - viewed in cross section - is smaller than the light sources facing leg and / or the Daylight facing thighs. In particular, the Lichtumlenkprofile can be contoured such that the ratio of height to width of the Lichtumlenkprofile - in an upright arrangement of the facade panels - is about 0.2 to 0.7. This increases the transparency of the facade panel when viewed vertically, while ensuring a sufficient deflection and thus a high luminosity of the panel safely.
    In particular, because of the relatively wide spacing of the Lichtumlenkprofile each other, which is made possible by the very sharp, abrasive irradiation, further light sources, preferably in the form of point light sources or LEDs or generally pixel-like light sources can be provided between the Lichtumlenkprofilen in an advantageous embodiment of the invention in particular in the form of a point light source grid, by means of which - in addition to illuminating the Lichtumlenkprofile or alternatively, when their irradiation is turned off - pixel-like images can be generated by appropriate control of the individual point light sources. As a result, the facade element or the prefabricated façade formed thereby becomes a media façade. The said point light sources, which can be arranged in the strip-shaped intermediate spaces between the Lichtumlenkprofilen, in addition to the aforementioned, at least one light source is provided which serves to irradiate the Lichtumlenkprofile. These additional point light sources can advantageously radiate the light directly to the front of the panel, so that they appear as a single point of light or together form a pixel image from a corresponding distance. 10/22 10
    The said point light sources between the Lichtumlenkprofilen can be mounted on suitable carriers such as support rails, which can advantageously extend parallel to the Lichtumlenkprofilen and / or can be designed as a diaphragm, which prevents the light emitted from the point light sources light to the panel back side behind a facade element brightens.
    The invention will be explained in more detail with reference to preferred embodiments and associated drawings. In the drawings show:
    1 is a schematic, perspective view of a building intent facade comprising a plurality of each rectangular illuminable facade panels according to an advantageous embodiment of the invention,
    2 shows a schematic vertical sectional view of a facade panel with front-side light source arrangement according to a further advantageous embodiment of the invention,
    3 is a plan view of the facade panel of FIG. 3,
    Fig. 4: a schematic representation of the beam path at the Lichtumlenkprofilen of Fig. 3, wherein a lower Lichtumlenkprofil shown essentially only the deflection of the artificial light irradiation, while an upper illustrated Lichtumlenkprofil additionally also the introduction of daylight in a lying behind the façade panel space serves and has a gutter-shaped Umlenkflächenkonturierung,
    Fig. 5 is a schematic vertical sectional view through a facade pan eel according to a further advantageous embodiment of the invention similar to FIG. 3, wherein the facade panel between the Lichtumlenkprofilen arranged 11/22 11 LED or point light sources to serve as a media facade, and
    6 shows a plan view of the facade panel from FIG. 6, which shows the grid-shaped arrangement of the LEDs between the deflection profiles.
    As shown in FIG. 1, the illuminable facade panels 1 can be mounted as front facade in front of a building facade, with a plurality of facade panels 1 together form the intent facade or can complement each other. As shown in FIG. 1, the arrangement of the facade panels 1 can be formed vertically or upright in front of a facade, wherein all facade panels can be arranged in one plane, but alternatively individual or groups of facade panels 1 can be arranged projecting and / or offset, to achieve a relief-like intent facade structure.
    The facade panels 1 can in this case be contoured in particular rectangular and approximately flat, as shown in Figures 2 and 3. The panel main surface 2, which forms the luminous surface of the facade panel and may be substantially planar and / or approximately, in particular only from one edge, can extend over the entire panel surface is formed by a plurality of elongated Lichtumlenkprofilen 3, in In parallel arrangement are spaced apart, so that the said panel main surface 2 per se is only an enveloping surface in which the Lichtumlenkprofile 3 are arranged. In a planar embodiment, this is a plane, but the panel main surface 2 can also be contoured or curved as described above and / or formed in the manner of a Knickspantfläche, in which case the Lichtumlenkprofile 1 no straight longitudinal axis, but have a corresponding curved or kinked longitudinal axis ,
    As particularly shown in FIG. 3, the Lichtumlenkprofile 3 may be in the form of long thin profile bars which have the same cross-sectional shape over the length of an extruded profile substantially. As particularly shown in FIG. 4, said Lichtumlenkprofile 3 advantageously have a nä-12/22 12 approximately triangular cross-sectional contour, wherein the Lichtumlenk-profiles 3 are advantageously arranged such that a first leg surface is substantially parallel to the building facade or to the panel main surface 2 extends. A second leg surface 5 of the triangular contoured light deflection profiles 3 faces a light source 7 integrated in the facade panel 1 and is set at an angle such that the light coming from the light source 7 is radiated obliquely downwards towards the panel front side and thus towards the outside of the building, cf. , Fig. 4.
    A third leg surface 6 of the triangular contoured Lichtumlenkprofile 3 may in particular be facing an upper half-space of the facade outside and possibly have a slightly trough-shaped contouring, as shown in Fig. 4 above Lichtumlenklamelle shows. Such a contouring of the third leg surface 6 can bring about an improved introduction of daylight through the facade panel into a building area located behind it.
    The Lichtumlenkprofile 3 can in this case be relatively widely spaced, wherein the distance between two adjacent Lichtumlenkprofilen 3 in the range of three to ten times, in particular three to five times the thickness or height of a Lichtumlenklamelle - measured in the direction of the aforementioned distance between two Lichtumlenkprofilen - may amount. In conventional Fassadenpaneelabmessungen the Lichtumlenkprofile 3 can be spaced from each other, for example, between 10 mm and 20 mm.
    As FIG. 2 shows, said light source 7 can be integrated into a frame 8 encircling the light-deflecting profiles 3, in particular being recessed therein, so that the light source 7 is invisibly arranged for a viewer of the facade panel. However, instead of a peripheral frame 8, the frame 8 may consist only of frame segments or frame legs, for example an upper and a lower frame part, which extend parallel to the Lichtumlenkprofilen 3. 13/22 13
    The Lichtumlenkprofile 3 may be mounted on said frame parts, but advantageously also at transversely to the longitudinal direction of Lichtumlenkprofile 3 extending intermediate carrier struts, which may be in the form of strained ropes or rods or the like.
    As shown in FIG. 2, the at least one light source 7 can be arranged on a front side of the light deflection profiles 3, so that the light deflection profiles 3 are irradiated from the panel front side and emit the light back to the panel front side.
    Advantageously, the arrangement of the light source 1 is very close to the panel main surface or plane defined by the light deflection profiles 3, so that the irradiation is carried out at a very acute angle to the said panel main surface. For example, a spacing of the light source 7 from the main panel surface defined by the Lichtumlenklamellen 3, perpendicular to said major surface less than 10 cm, in particular only 1 cm to 5 cm, especially if the facade panel 1 overall dimensions of, for example, 1 / 2 m to 1 m high.
    The light source 7 mentioned can in particular consist of one or more rows of point light sources arranged parallel to one another, for example in the form of LEDs, which can be arranged substantially parallel to the main panel surface at the lower edge of the facade panel 1. The point light sources are distributed along the lower extension of the facade panel 1.
    In order to substantially completely capture the light emitted by the light sources or LEDs and to cast them substantially completely onto the light deflection profiles 3, deflection optics 9 are associated with the light sources 7, for example in the form of the lens 10 shown in FIG. 4 and / or a lens Light sources associated reflector. Advantageously, in this case each point light source can be assigned its own deflection optics which can be designed in the manner described above such that the light emitted by the light source is formed into a pyramid-shaped, in particular obliquely pyramidal, beam trans-14/22 14, which is a rectangular Surface of the panel main surface illuminated. The deflection optics can be such that each point light source illuminates the entire facade panel surface. Alternatively, only partial surface pieces of said main panel surface can be illuminated so that a plurality of point light sources and the light pyramids or patches generated therefrom complement each other and the entire panel is illuminated approximately uniformly.
    As shown in FIG. 2, the arrangement of the light source 7 and the associated deflection optics 9 can be such that a main radiation direction 11 to the panel main surface assumes an angle of less than 10 °. The deflection profiles 3, in particular their second leg surfaces 5, can be designed and arranged such that the light beam emitted by the light deflection profiles 3 is likewise directed at an acute angle to the main panel surface and thereby has an expansion of less than 25 °, the radiation of the radiation being substantially parallel to the facade can reach up to a spread angle to the facade of about 20 °.
    In order to use the façade panel 1 for a media façade, which can display television images or similar pixel representations, a multiplicity of point light sources, for example in the form of LEDs, which form an LED matrix in the manner of a pixel arrangement, can be arranged between the elongate light deflection profiles 3. It can be arranged in each space between the Lichtumlenk lamellae 3 a number of LEDs, but possibly only in every second or in every third gap between the deflection profiles 3, see. Fig. 6.
    The said LEDs can in each case be mounted on a carrier rail 12, which can be attached to the back in the region of the intermediate spaces between two adjacent Lichtumlenkprofilen 3. The mentioned carrier rail 12 may be U-shaped, for example, in cross-section and / or be coated in a reflective manner in order to radiate the light emitted by the LEDs completely towards the panel front side. 15/22
