Description

Die Erfindung betrifft einen Beleuchtungskörper insbesondere zur Verwendung als Decken- und/oder Wandelement, bestehend aus einem Rahmenelement und zumindest einem für Licht wenigstens teilweise durchlässigen Medium, auf der dem Betrachter zugewandten Seite.The invention relates to a lighting fixture, in particular for use as a ceiling and / or wall element, consisting of a frame element and at least one light-permeable medium, on the side facing the observer.

Beleuchtungskörper der gattungsgemäßen Art werden bevorzugt für abgehängte Decken und ggf. auch Wände eingesetzt. Entsprechend der Raumgröße erfolgt hierbei eine symmetrische oder asymmetrische Unterteilung der Decken- bzw. Wandfläche, wobei die Installation der verwendeten Beleuchtungsmittel einschl. der notwendigen Steuerungsgeräte an der Wand oder Decke erfolgt. Im Weiteren weisen diese Art von Beleuchtungskörpern ein dem Betrachter zugewandtes Medium auf, welches zumindest teilweise lichtdurchlässig ist und einerseits eine Raumausleuchtung ermöglicht und andererseits den Blick auf die Installationseinrichtungen verwehrt. Üblicherweise werden als Beleuchtungsmittel Leuchtstoffröhren, Strahler oder andere großflächige Beleuchtungsmittel mit indirekter Lichtemission verwendet, wobei in der Regel beabsichtigt ist, eine gleichmäßige und lichtintensive Ausleuchtung des Raums vorzunehmen. Durch die Verwendung eines lichtdurchlässigen Mediums muss im Weiteren ein ausreichender Abstand zwischen den Beleuchtungsmitteln und dem verwendeten Medium eingehalten werden, um eine gleichmäßige Ausleuchtung durch den Beleuchtungskörper zu schaffen und eine unerwünschte Schattenbildung zu vermeiden. Falls eine zu dichte Anordnung der Beleuchtungsmittel hinter dem Medium gewählt wird, entstehen einzelne helle Lichtkegel, welche unerwünscht sind und darüber hinaus zu einer ungleichmäßigen Ausleuchtung und Schattenwirkung des Raums führen.Lighting fixtures of the generic type are preferably used for suspended ceilings and possibly also walls.

DE 299 15 399 U beschreibt einen kompakten kachelartigen Beleuchtungskörper (1), bestehend aus einem Basiselement und einem harten Diffusor für Licht auf der dem Betrachter zugewandten Seite, welcher einerseits einen Blick in den Beleuchtungskörper ausschließt und darüber hinaus die emittierenden LEDs diffus.erscheinen lässt, wobei hinter dem Diffusor eine Vielzahl von LEDs vorgesehen sind, welche zumindest in einer Ebene liegend angeordnet und jeweils einzeln und individuell durch eine Steuereinheit mit Spannung beaufschlagbar sind. Dabei ist eine Steuereinheit vorgesehen ist, über die die Intensität der LEDs beeinflussbar ist und die jeweilige Auswahl der LEDserfolgt. Die LEDs sind gruppenweise zur Verwendung als Hintergrundstrahlung zusammengefasst angeordnet und emittieren unterschiedliche Spektralfarben, so dass eine additive Farbmischung zur Erzeugung von Farbbildern führt. Die LEDs sind homogen hinter dem Medium verteilt angeordnet.

Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.According to the invention, a lighting device with the features of claim 1 is given to achieve this object. Advantageous embodiments are the subject of the dependent claims.

Es ist vorgesehen, dass hinter dem Medium eine Vielzahl von Einzellichtquellen vorgesehen sind, weiche zumindest in einer Ebene liegend angeordnet und jeweils einzeln und individuell durch eine Steuereinheit mit Spannung beaufschlagbar sind. Durch die Vielzahl von Einzellichtquellen können entsprechend der jeweils getroffenen Auswahl und Anordnung feststehende oder variable Muster hinter dem Medium erzeugt werden, so dass bei entsprechender Auswahl von kleindimensionierten Einzellichtquellen eine punktuelle Lichtimmission erfolgt. Bei entsprechender Anordnung der Einzellichtquellen und individueller Ansteuerung kann beispielsweise ein Sternenhimmel erzeugt werden, der im Weiteren mit besonderen Sternenkonstellationen, insbesondere Sternzeichen, mit einer erhöhten Intensitätsabstrahlung der Einzellichtquellen zu einem optisch sehr reizvollen Beleuchtungskörper für den Betrachter führt. Die hierzu nötige Steuereinheit übernimmt hierbei die Auswahl der mit Spannung zu beaufschlagenden Einzellichtquellen und kann ggf. deren Intensität beeinflussen, so dass verschiedene, wechselnde Sternenkonstellationen einerseits möglich sind oder aber auch die gezielte Darstellung von einzelnen Sternenbildern ermöglicht wird. Vorzugsweise werden für die Lichtquellen Laser- oder Leuchtdioden (LEDs) eingesetzt, welche eine identische oder unterschiedliche Spektralfarbe aussenden. Es besteht somit die Möglichkeit, besondere Farbgestaltungen vorzunehmen und verschiedene Gruppen von Einzellichtquellen als Hintergrundstrahlung und andere zur Erzeugung einer sternenförmigen Punktquellenstrahlung zu verwenden.It is provided that behind the medium, a plurality of individual light sources are provided, which are arranged lying at least in one plane and each individually and individually acted upon by a control unit with voltage. As a result of the multiplicity of individual light sources, fixed or variable patterns can be generated behind the medium in accordance with the respectively selected selection and arrangement, so that a punctual light immission takes place with appropriate selection of small-dimensioned individual light sources. With appropriate arrangement of the individual light sources and individual control, for example, a starry sky can be generated, which in the following with special star constellations, in particular star signs, with an increased intensity radiation of the individual light sources to a visually very attractive lighting fixture leads to the viewer. The necessary control unit in this case assumes the selection of voltage to be acted upon individual light sources and can possibly influence their intensity, so that different, changing star constellations are on the one hand possible or even the targeted representation of individual star images is possible. Preferably, laser or light-emitting diodes (LEDs) are used for the light sources, which emit an identical or different spectral color. It is therefore possible to make special color designs and to use different groups of individual light sources as background radiation and others for generating a star-shaped point source radiation.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass das Medium aus einer mattierten Glasscheibe, einer Lackfolie oder einer gespannten, insbesondere transluzenden, Folie besteht. Durch die Verwendung einer beispielsweise mattierten Glasscheibe wird ein Einblick in den Beleuchtungskörper durch den Betrachter ausgeschlossen, so dass die vorhandenen Instaltationseinrichtungen nicht wahrgenommen werden. Dagegen werden die Einzellichtquellen, sofern sie angesteuert werden, schwach emittierend wahrgenommen und erzeugen die gewünschten Lichteffekte. Alternativ ist die Verwendung einer vorzugsweise dunkelblauen Lackfolie möglich, welche die vorgenannten Vorteile ebenfalls aufweist. Besonders vorteilhaft ist die Ausgestaltung der Beleuchtungskörper mit einer gespannten, insbesondere transluzenten Folie, welche einerseits einen Blick in den Beleuchtungskörper ausschließt und darüber hinaus die emittierenden Einzellichtquellen diffus erscheinen lässt. Der besondere Vorteil einer Lackfolie oder ggf. einer transluzenten Folie besteht im Weiteren darin, dass ggf. innerhalb des Beleuchtungskörpers auch Lautsprecher integriert und somit die Schallwellen in den Raum durch die Folie hindurch abgestrahlt werden können.
Zur Erzeugung der unterschiedlichen Lichteffekte können in vorteilhafter Weise die Lichtquellen im Weiteren gruppenweise zusammengefasst und über die Steuereinheit mit Spannung beaufschlagt werden.In a further embodiment of the invention, it is provided that the medium consists of a frosted glass pane, a paint film or a stretched, in particular translucent, film. By using a frosted glass, for example, an insight into the lighting fixture is excluded by the viewer, so that the existing Instaltationseinrichtungen are not perceived. In contrast, the individual light sources, if they are controlled, perceived weakly emitting and produce the desired lighting effects. Alternatively, the use of a preferably dark blue paint film is possible, which also has the aforementioned advantages. The design of the lighting fixtures is particularly advantageous with a tensioned, in particular translucent, film which, on the one hand, excludes a view into the lighting fixture and moreover makes the emitting individual light sources appear diffuse. The particular advantage of a paint film or, if appropriate, of a translucent film is, furthermore, that possibly also speakers are integrated within the lighting fixture and thus the sound waves can be radiated into the room through the film.
In order to generate the different light effects, the light sources can be grouped together in groups and the voltage applied to the control unit.

Um differenzierte und unterschiedliche Lichtintensitäten unabhängig von der vorhandenen Steuereinheit zu erzeugen ist im Weiteren vorgesehen, dass die Lichtquellen in zumindest zwei parallel zum Medium verlaufenden Ebenen stehend oder liegend angeordnet sind.In order to produce differentiated and different light intensities independently of the existing control unit, it is further provided that the light sources are arranged standing or lying in at least two planes running parallel to the medium.

Die verwendeten Lichtquellen können insbesondere aus einer Diodenmatrix bestehen, welche wahlweise zur Erzeugung einer Hintergrundausleuchtung oder zur Erzeugung eines Sternenbilds verwendet werden. Alternativ können für die Lichtquellen Laser- oder Leuchtdioden (LEDs) verwendet werden, welche eine ultrabreite oder engstrahlende Immission besitzen. Die Verteilung der Lichtquellen kann in vorteilhafter Ausgestaltung der Erfindung in derart erfolgen, dass die Lichtquellen inhomogen oder homogen hinter dem Medium angeordnet sind oder dass die Lichtquellen in einfachen geometrischen Mustern, insbesondere linienförmig, hinter dem Medium angeordnet sind. Durch eine inhomogene Anordnung der Lichtquellen wird der Charakter des Sternenhimmels besonders deutlich, weil die einzelnen Sterne für einen Betrachter von der Erde aus isotrop verteilt sind, während hingegen bei einer homogenen Lichtquellenverteilung bestimmte graphische Muster darstellbar sind. Im Fall einer beispielsweise linienförmigen Anordnung von einzelnen Lichtquellen in Verbindung mit einem Steuerimpuls in aufsteigender Reihenfolge zu jeder einzelnen Lichtquelle kann beispielsweise eine Sternschnuppe oder dergleichen kurzzeitig aufblitzend dargestellt werden. Die einzelnen Lichtquellen können hierbei gruppenweise zusammengefasst sein oder aber auch einzeln mit Spannung durch die Steuereinheit beaufschlagt werden, wobei im Fall einer Einzelansteuerung eine Beschaltung mit Vorwiderständen notwendig ist, während hingegen bei einer Reihenschaltung von mehreren Lichtquellen ein ausreichend hoher Lastwiderstand vorliegt. Ferner können die Lichtquellen zu Buchstaben- oder Zahlengruppen oder Bildern zusammengefasst hinter dem Medium angeordnet sein, so dass zeitweise eine Informationswiedergabe oder Bildgestaltung ermöglicht wird und die Verwendbarkeit der Beleuchtungskörper erweitert. In vorteilhafter Weise können die Bilder oder Informationen nur kurzzeitig dargestellt und ggf. überblendet werden, so dass besondere optische Eindrücke entstehen und die Beleuchtungskörper auch als Werbefläche, Werbeobjekt mit wechselndem Inhalt verwendet werden können.The light sources used may in particular consist of a diode matrix, which are optionally used for generating a background illumination or for generating a constellation of stars. Alternatively, for the light sources laser or light emitting diodes (LEDs) can be used, which have an ultra-wide or narrow-beam immission. In an advantageous embodiment of the invention, the light sources can be distributed in such a way that the light sources are arranged inhomogeneously or homogeneously behind the medium or that the light sources are arranged in simple geometric patterns, in particular linear, are arranged behind the medium. Due to an inhomogeneous arrangement of the light sources, the character of the starry sky becomes particularly clear, because the individual stars are distributed isotropically for a viewer from the earth, whereas, in contrast, given a homogeneous light source distribution, certain graphic patterns can be represented. In the case of an example linear arrangement of individual light sources in conjunction with a control pulse in ascending order to each individual light source, for example, a shooting star or the like can be displayed briefly flashing. The individual light sources may in this case be combined in groups or else individually supplied with voltage by the control unit, wherein in the case of a single control, a circuit with series resistors is necessary, whereas in a series connection of multiple light sources, a sufficiently high load resistance is present. Furthermore, the light sources can be arranged in groups of letters or numbers or images grouped behind the medium, so that at times an information reproduction or image design is made possible and extends the usability of the lighting fixture. Advantageously, the images or information can be displayed only briefly and possibly faded, so that special visual impressions arise and the lighting fixtures can also be used as advertising space, advertising object with changing content.

In weiterer besonderer Ausgestaltung der Erfindung ist vorgesehen, dass die Lichtquellen für die Hintergrundstrahlung vorzugsweise in einer zweiten, von dem Medium entfernt liegenden Ebene angeordnet sind. Durch die Ausbildung einer zweiten Ebene für die einzelnen Lichtquellen kann bei ansonsten in gleicher Intensitätsabstrahlung auf Grund des vorhandenen Abstands zum Medium eine Reduzierung der Lichtimmission und unter Ausnutzung der auftretenden Vielfachstreuung hinter dem Medium zu einer schwachen gewünschten Hintergrundstrahlung führen.In a further embodiment of the invention, it is provided that the light sources for the background radiation are preferably arranged in a second plane remote from the medium. The formation of a second level for the individual light sources can lead to a weak desired background radiation, otherwise with the same intensity radiation due to the existing distance to the medium, a reduction of the light immission and taking advantage of the occurring multiple scattering behind the medium.

Um die Lichtintensität der einzelnen Lichtquellen unabhängig von der Steuereinheit regulieren zu können ist in besonderer Ausgestaltung der Erfindung vorgesehen, dass die Lichtquellen senkrecht oder schräg verlaufend zum Medium axial verstellbar ausgebildet sind, wobei die Lichtquellen entweder unmittelbar oder mittelbar über eine Hülse axial verschiebbar in einer Halterung befestigt sind. Die Hülse oder die Halterung der Lichtquellen kann im Weiteren in einer zweiten Folie, einer Rück- oder Zwischenwand oder zumindest einem anderen flexiblen und membranartig beweglichen Trägermaterial hinter dem Medium befestigt sein. Durch die vorgeschlagene Halterung der einzelnen Lichtquellen kann bei der Montage beispielsweise eine Nachjustierung erfolgen und ein gewünschter Abstand zwischen der Lichtquelle und dem Medium variabel eingestellt werden, welcher unabhängig von der Steuereinheit eine Beeinflussung der wahrzunehmenden Lichtintensität ermöglicht. In vorteilhafter Weise wird hierbei die Verwendung einer Hülse vorgeschlagen, in der die einzelnen Lichtquellen, insbesondere die LEDs befestigt sind, beispielsweise verklebt, während die Hülse in der vorgesehenen Halterung axial beweglich verschiebbar ist.In order to regulate the light intensity of the individual light sources independently of the control unit is provided in a particular embodiment of the invention that the light sources are perpendicular or inclined to the medium axially adjustable, the light sources either directly or indirectly via a sleeve axially displaceable in a holder are attached. The sleeve or the holder of the light sources can be further secured behind the medium in a second film, a rear or intermediate wall or at least one other flexible and membrane-like movable support material. By the proposed mounting of the individual light sources, for example, a readjustment during assembly and a desired distance between the light source and the medium can be variably adjusted, which allows independent of the control unit to influence the perceived light intensity. Advantageously, in this case the use of a sleeve is proposed in which the individual Light sources, in particular the LEDs are fixed, for example glued, while the sleeve is axially movable in the holder provided.

In weiterer besonderer Ausgestaltung der Erfindung ist vorgesehen, dass das Medium, die zweite Folie oder das Trägermaterial als Lautsprechermembran verwendbar ist und somit der Beleuchtungskörper nicht nur zur Erzeugung unterschiedlicher Beleuchtungsvarianten eingesetzt werden kann, sondern darüber hinaus durch die Anordnung von Lautsprechern innerhalb des Beleuchtungskörpers und im speziellen Fall der Ausbildung des Mediums oder Trägermaterials als Lautsprechermembran zur Abstrahlung von Musik etc. verwendet werden kann. Im zuletzt genannten Fall werden sogenannte Transducer unmittelbar auf dem Medium bzw. Trägermaterial befestigt. Die Ansteuerung der Lautsprechermembrane kann hierbei unmittelbar über einzelne Zuleitungen oder über die Spannungsversorgungsleitung mit einer hochfrequenten Signalüberlagerung erfolgen.In a further particular embodiment of the invention, it is provided that the medium, the second film or the carrier material can be used as a speaker membrane and thus the lighting fixture can be used not only to produce different lighting variants, but also by the arrangement of speakers within the lighting fixture and in the special case of the formation of the medium or carrier material can be used as a speaker diaphragm for the emission of music, etc. In the latter case, so-called transducers are attached directly to the medium or carrier material. The control of the speaker diaphragm can be done directly via individual leads or via the power supply line with a high frequency signal overlay.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass über die Steuereinheit die Intensität der Lichtquellen beeinflussbar ist und die jeweilige Auswahl der Lichtquellen erfolgt, wobei wahlweise ein internes oder externes Gerät, insbesondere eine frei programmierbare Steuerung (SPS) einsetzbar ist und somit jegliche individuelle Ansteuerung der Lichtquellen ermöglicht und damit beliebige Sternenkonfigurationen oder beliebige geometrische Gebilde darstellbar sind. In weiterer besonderer Ausgestaltung der Erfindung ist vorgesehen, dass die Lichtquellen gruppenweise zusammengefasst angeordnet sind und gleiche oder unterschiedliche Spektralfarben emittieren, so dass eine additive Farbmischung zur Erzeugung von Farbbildern führt. Durch die Verwendung von engstrahlenden LEDs und die gruppenweise Anordnung von LEDs unterschiedlicher Spektralfarben kann somit unter gleichzeitiger Intensitätsbeeinflussung die Darstellung von jeder Mischfarbe erfolgen, so dass sogar bildliche Darstellungen ermöglicht werden.In a further embodiment of the invention, it is provided that via the control unit, the intensity of the light sources can be influenced and the respective selection of the light sources takes place, optionally an internal or external device, in particular a freely programmable controller (PLC) can be used and thus any individual control of Light sources allows and thus any star configurations or any geometric structure can be displayed. In a further particular embodiment of the invention, it is provided that the light sources are arranged in groups in groups and emit the same or different spectral colors, so that additive color mixing leads to the production of color images. By using narrow-beam LEDs and the group-wise arrangement of LEDs of different spectral colors, the representation of each mixed color can thus take place with simultaneous intensity influence, so that even pictorial representations are made possible.

Zur weiteren Raumausleuchtung und Lichtgestaltung ist im Weiteren vorgesehen, dass zumindest teilweise entlang des Rahmenelements weitere Beleuchtungselement, beispielsweise in Form von Leuchtstoffröhren, Einzellampen oder dergleichen angeordnet sind, welche die normale Raumausleuchtung vornehmen. Die Beleuchtungskörper können ferner mit Musik- oder Tonwiedergabegeräten ausgestattet sein, so dass eine optische und akustische Präsentation erfolgen kann.For further room illumination and lighting design is further provided that at least partially along the frame element further lighting element, for example in the form of fluorescent tubes, individual lamps or the like are arranged, which make the normal room illumination. The lighting fixtures may also be equipped with music or sound reproduction devices, so that a visual and acoustic presentation can take place.

Die Erfindung wird im Weiteren an Hand der Figuren nochmals beschrieben.The invention will be described again with reference to the figures.

Figur 1 zeigt in einer Draufsicht einen erfindungsgemäßen Beleuchtungskörper 1, welcher als Decken- und/oder Wandelement verwendet werden kann und mit entsprechenden Halterungen befestigt wird. Der Beleuchtungskörper 1 besteht aus einem Rahmenelement 2, welches den individuellen Raumanordnungen und Gestaltungswünschen angepasst werden kann. Mehrere dieser Beleuchtungskörper 1 werden nebeneinander platziert, so dass auch größere Decken bzw. Wände abgedeckt werden können. Zum besseren Einblick in den Beleuchtungskörper 1 ist dieser ohne teilweise lichtdurchlässiges Medium dargestellt. Innerhalb des Rahmenelements 2 sind auf einem Trägermaterial 3, welches beispielsweise aus einer Folie, einer Rückwand- oder Zwischenwand oder ggf. aus einem flexiblen membranartig beweglichen Trägermaterial besteht, eine Vielzahl von Einzellichtquellen 4 angeordnet. Die Lichtquellen 4 sind im gezeigten Ausführungsbeispiel inhomogen über das Trägermaterial 3 verstreut angeordnet und bestehen aus einzelnen Leuchtdioden (LED's) 5, welche teilweise liegend bzw. stehend angeordnet sind. Im Weiteren befinden sich auf dem Trägermaterial 3 vier Lautsprecher 6, welche zur Beschallung des Raums vorgesehen sind. Als Medium vor den Einzellichtquellen 4 kann beispielsweise eine mattierte Glasscheibe eingesetzt werden, welche den Einblick in den Beleuchtungskörper 1 für einen Betrachter auf die vorhandene Installation und die Einzellichtquellen 4 verwehrt. Bei der Verwendung einer Lackfolie oder insbesondere einer transluzenten Folie kann darüber hinaus durch die vorhandenen Lautsprecher 6 eine Beschallung vorgenommen werden. Die Lichteffekte und Beschallung kann hierbei ggf. aufeinander abgestimmt werden, so dass der Betrachter den Eindruck eines Sternenhimmels hat und durch die gleichzeitige musikalische Darbietung die optischen Reize verstärkt wahrnimmt. FIG. 1 shows a plan view of a lighting fixture 1 according to the invention, which can be used as a ceiling and / or wall element and is fastened with corresponding brackets. The lighting fixture 1 consists of a frame element 2, which can be adapted to the individual room arrangements and design wishes. Several of these lighting fixtures 1 are placed next to each other, so that larger ceilings or walls can be covered. For better insight into the lighting fixture 1 this is shown without partially transparent medium. Within the frame element 2, a plurality of individual light sources 4 are arranged on a carrier material 3, which consists for example of a film, a back wall or intermediate wall or optionally of a flexible membrane-like movable carrier material. In the exemplary embodiment shown, the light sources 4 are arranged in an inhomogeneous manner over the carrier material 3 and consist of individual light-emitting diodes (LEDs) 5, which are arranged partially lying or standing. In addition, there are four speakers 6 on the substrate 3, which are provided for sound of the room. As a medium in front of the individual light sources 4, for example, a frosted glass pane can be used, which denies the insight into the lighting fixture 1 for a viewer on the existing installation and the individual light sources 4. When using a paint film or in particular a translucent film can also be made by the existing speakers 6 a sound. If necessary, the light effects and sound can be coordinated with each other, so that the viewer has the impression of a starry sky and perceives the visual stimuli through the simultaneous musical performance.

Figur 2 zeigt in einer geschnittenen Seitenansicht den Beleuchtungskörper 1 gemäß Figur 1. Der Beleuchtungskörper 1 wird gebildet durch das Rahmenelement 2, in welchem das Trägermaterial 3 durch Abstandsbolzen 7 befestigt ist. Im gezeigten Ausführungsbeispiel handelt es sich um eine Zwischenwand als Trägermaterial 3, auf welcher im Weiteren die einzelnen Leuchtdioden 5 in vorhandenen Bohrungen 8 befestigt sind. Anstelle der Zwischenwand besteht im Weiteren die Möglichkeit, die Leuchtdioden unmittelbar auf der Rückwand oder einer weiteren gespannten Folie zu befestigen. In besonderer Ausgestaltung der Erfindung kann die Trägerwand als Lautsprechermembran ausgebildet und mit der entsprechenden Elektronik zur Schallwellenerzeugung vorgesehen sein. Die einzelnen Leuchtdioden 5 sind im gezeigten Ausführungsbeispiel in einer Hülse 9 aufgenommen, welche ein Außengewinde 10 aufweist. Die Hülse 9 kann im Weiteren mit den Außengewinde 10 unmittelbar in dem Trägermaterial 3 eingeschraubt werden oder ggf. durch außenliegende Muttern 11 befestigt werden. Die Ansteuerung der Leuchtdioden 5 erfolgt über eine Steuereinheit 12, welche mit einer Spannungsversorgung ebenso wie die weiteren Lichtquellen ausgestattet ist. Jede einzelne Leuchtdiode oder Leuchtdiodengruppe weist eine Zuleitung 13 zu der Steuereinheit 12 auf und kann somit individuell und einzeln oder gruppenweise mit Spannung beaufschlagt werden. Die einzelnen Leuchtdioden 5 weisen im Weiteren zur gespannten Folie 14 einen unterschiedlichen Abstand auf und führen durch ihre engstrahlende oder breitstreuende Wirkung zu unterschiedlich großen Lichtpunkten auf der Folie 14. Die Folie 14 verhindert, wie bereits oben ausgeführt, einen Einblick in die Beschaltung und Anordnung der Einzellichtquellen, so dass der Betrachter des Beleuchtungskörpers 1 nur die mit Spannung beaufschlagten einzelnen Leuchtdioden 5 wahrnimmt. Entsprechend dem Steuerungsprogramm der Steuereinheit 12 können somit unterschiedliche Sternenkonstellationen und einzelne Sternzeichen durch die Leuchtdioden 5 dargestellt werden. Zur Erzielung einer optisch reizvollen Hintergrundstrahlung können besondere beispielsweise blau emittierende Leuchtdioden 5 eingesetzt werden, welche liegend auf dem Trägermaterial 3 befestigt sind. Alternativ besteht die Möglichkeit, dass ein weiteres Trägermaterial in zwei oder mehreren Ebenen hintereinander zur Befestigung der Leuchtdioden 5 verwendet wird. Randseitig sind in dem Rahmenelement 2 im Weiteren Beleuchtungselemente in Form von Leuchtstoffröhren 15 längsseitig einschließlich der notwendigen Beschaltung angeordnet. Die Folie 14 ist in hierfür speziell ausgebildete Befestigungsschienen 16 eingeklemmt, welche die Aufnahme eines Keders 17 ermöglichen, der an den Rändern der Folie 14 beispielsweise angeschweißt ist. FIG. 2 shows in a sectional side view of the lighting fixture 1 according to FIG. 1 , The lighting fixture 1 is formed by the frame element 2, in which the support material 3 is fixed by spacer bolts 7. In the exemplary embodiment shown, it is an intermediate wall as a carrier material 3, on which in the following the individual LEDs 5 are mounted in existing holes 8. Instead of the intermediate wall there is the further possibility of the LEDs directly on the rear wall or another stretched film Fasten. In a particular embodiment of the invention, the support wall may be formed as a speaker diaphragm and provided with the corresponding electronics for sound wave generation. The individual light emitting diodes 5 are accommodated in the embodiment shown in a sleeve 9, which has an external thread 10. The sleeve 9 can subsequently be screwed directly into the carrier material 3 with the external thread 10 or, if necessary, be fastened by external nuts 11. The control of the LEDs 5 via a control unit 12, which is equipped with a power supply as well as the other light sources. Each individual light-emitting diode or light-emitting diode group has a supply line 13 to the control unit 12 and can thus be individually and individually or in groups acted upon by voltage. The individual light-emitting diodes 5 furthermore have a different spacing from the tensioned film 14 and, due to their narrow-beam or broad-scattering effect, lead to differently sized light spots on the film 14. The film 14 prevents, as already stated above, an insight into the wiring and arrangement of the film Single light sources, so that the viewer of the lighting fixture 1 perceives only the voltage applied to individual LEDs 5. According to the control program of the control unit 12, different star constellations and individual star signs can thus be represented by the LEDs 5. To achieve a visually attractive background radiation, it is possible, for example, to use special blue-emitting light-emitting diodes 5, which are mounted lying on the carrier material 3. Alternatively, there is the possibility that another carrier material is used in two or more levels one behind the other for fixing the LEDs 5. On the edge side lighting elements in the form of fluorescent tubes 15 are arranged along the side including the necessary circuitry in the frame member 2 hereinafter. The film 14 is clamped in specially trained mounting rails 16, which allow the inclusion of a welt 17, which is welded to the edges of the film 14, for example.

Figur 3 zeigt zwei Leuchtdioden 5 in einer stehenden bzw. liegenden Befestigungsart. Die stehende Leuchtdiode 5 ist in der Hülse 9 mit Außengewinde 10 in einer Bohrung 18 eingesetzt und beispielsweise verklebt, wobei die Zuleitungen 13 nach hinten aus der Hülse 9 herausgeführt sind. Zur Befestigung der Hülse 9 in dem nicht dargestellten Trägermaterial ist im Weiteren eine Mutter 11 vorgesehen, welche ggf. oberhalb und unterhalb des Trägermaterials gekontert werden kann. Die Zuleitungen 13 werden im Weiteren mit der nicht dargestellten Steuereinheit 12 verbunden, so dass jede einzelne Leuchtdiode 5 individuell und einzeln angesteuert werden kann. Die Hülse 9 besteht aus einem Diodenaufnahmekörper 9 und einem Hülsenkörper 20, welche für die stehend angeordneten Leuchtdioden 5 miteinander verbunden, beispielsweise verschraubt oder verklebt, sind. Bei einer liegenden Anordnung der Leuchtdioden 5 wird lediglich der Diodenaufnahmekörper 19 verwendet und unmittelbar auf dem Trägermaterial 3 beispielsweise aufgeklebt. FIG. 3 shows two LEDs 5 in a standing or lying attachment. The standing light-emitting diode 5 is inserted in the sleeve 9 with external thread 10 in a bore 18 and, for example, glued, wherein the leads 13 are led out to the rear of the sleeve 9. For securing the sleeve 9 in the carrier material, not shown, a nut 11 is provided in the following, which may optionally be counteracted above and below the carrier material. The supply lines 13 are subsequently connected to the control unit 12, not shown, so that each individual light-emitting diode 5 can be controlled individually and individually. The sleeve 9 consists of a diode receiving body 9 and a sleeve body 20, which are connected to each other for the vertically arranged LEDs 5, for example screwed or glued, are. In a horizontal arrangement of the LEDs 5, only the diode receiving body 19 is used and adhered directly to the substrate 3, for example.

Figur 4 zeigt ein Blockschaltbild der Steuereinheit 12, welche mit Betriebsspannung über die Zuleitung 21 versorgt wird. Im Weiteren sind an die Steuereinheit 12 die Leuchtstoffröhren 15 mit Ihren zugehörigen Drosseln 22 angeschlossen und können somit wahlweise und ebenfalls individuell zur Beleuchtung hinzugeschaltet werden. Des Weiteren sind an die Steuereinheit 12 verschiedene Anordnungen von Leuchtdioden 5 aufgeschaltet. Im einfachsten Fall erfolgt die Ansteuerung einer einzelnen Leuchtdiode 5 über einen Vorwiderstand 22. Die zweite Beschaltungsart zeigt zwei parallel geschaltete Leuchtdioden 5, welche ebenfalls über einen Vorwiderstand 22 an die Steuereinheit 12 angeschlossen sind. Neben der einzelnen Ansteuerung von Leuchtdioden 5 besteht die Möglichkeit eine Kette von Leuchtdioden 5, welche teilweise aus einer Reihen- und einer Parallelschaltung von Leuchtdioden 5 besteht, unmittelbar an einen Ausgang der Steuereinheit 12 anzuschließen, so dass mehrere Leuchtdioden 5 gruppenweise zusammengefasst bei Spannungsbeaufschlagung leuchten. Dies bietet sich beispielsweise für eine Hintergrundbeleuchtung des Sternenhimmels an. Die Steuereinheit 5 weist darüber hinaus Drehknöpfe 23 zur Einstellung der Intensität und der Ablaufgeschwindigkeit auf. Diese manuelle Einstellung kann ggf. durch eine frei programmierbare Steuerung, welche in der Steuereinheit 12 integriert ist, in der Art unterstützt werden, dass feststehende Programme bestimmter Sternenkonstellationen, Sternenhimmel, Stemschnuppendurchgänge oder Sternenbilder in einem zuvor gewählten Programm ablaufen. Im Weiteren besteht die Möglichkeit durch externe Zuleitungen das Programm zu steuern, so dass jederzeit eine äußere Beeinflussung des ablaufenden Programms vorgenommen werden kann. FIG. 4 shows a block diagram of the control unit 12, which is supplied with operating voltage via the supply line 21. In addition, the fluorescent tubes 15 are connected to their associated chokes 22 to the control unit 12 and can thus optionally and also individually connected to the lighting. Furthermore, various arrangements of light emitting diodes 5 are connected to the control unit 12. In the simplest case, the control of a single light-emitting diode 5 via a series resistor 22. The second Beschaltungsart shows two parallel LEDs 5, which are also connected via a series resistor 22 to the control unit 12. In addition to the individual control of light emitting diodes 5, there is the possibility of a chain of light emitting diodes 5, which consists in part of a series and a parallel connection of light emitting diodes 5, to connect directly to an output of the control unit 12, so that a plurality of light-emitting diodes 5 summarized in groups when voltage is applied. This is useful, for example, for backlighting the starry sky. The control unit 5 also has knobs 23 for adjusting the intensity and the flow rate. This manual adjustment may optionally be assisted by a freely programmable controller integrated in the control unit 12 in such a way that fixed programs of certain star constellations, starry skies, star-flute passages or constellations run in a previously selected program. In addition, it is possible to control the program by external supply lines, so that at any time an external influence on the running program can be made.
