Description

Die Erfindung betrifft eine Beleuchtungsanlage der im Oberbegriff des Patentanspruchs 1 angegeben Art.The invention relates to a lighting system specified in the preamble of claim 1.

Beleuchtungsanlagen dieser Art stehen verbreitet in den genannten Anwendungsgebieten im Einsatz und sind von daher bekannt. Bei diesen Beleuchtungsanlagen sind die Leuchtkörper räumlich getrennt von den zugehörigen Schalt- und Dimmeinheiten angeordnet und über elektrische Leitungen mit diesen verbunden. Bei der Film- und Fernsehbeleuchtungstechnik ist es z.B. üblich, daß die Leuchtkörper, insbesondere Scheinwerfer, in einer großen Zahl oder großen Wattleistung pro Flächeneinheit fest installiert oder an Tragschienenanordnungen begrenzt verfahrbar über der zu beleuchtenden Studiofläche hängen und über eine feste Verkabelung oder Schleppkabel individuell mit einer Versorgungsspannung zwischen 0 und 220 V gespeist werden. Diese individuellen Versorgungsspannungen werden über relativ lange Kabel von einem Elektroinstallationsraum, in welchem die einzelnen Schalt- und Dimmeinheiten zusammengefaßt untergebracht sind, herangeführt. Die Schalt-und Dimmeinheiten ihrerseits werden über Steuerkabel von einem wieder im Studio selbst angeordneten Lichtregelpult durch einen Beleuchter fernbetätigt und entsprechend dessen optischer Wahrnehmung und nach Regieanweisungen eingestellt.Lighting systems of this type are widely used in the fields of application mentioned and are therefore known. In these lighting systems, the luminous elements are arranged spatially separate from the associated switching and dimming units and connected to them via electrical lines. In film and television lighting technology it is e.g. It is common for the light fixtures, in particular headlights, to be permanently installed in large numbers or large wattages per unit area or to be limitedly movable on mounting rail arrangements above the studio surface to be illuminated and to be fed individually with a supply voltage between 0 and 220 V via fixed cabling or trailing cables. These individual supply voltages are brought in via relatively long cables from an electrical installation room in which the individual switching and dimming units are housed together. The switching and dimming units, for their part, are remotely operated via control cables from a light control panel which is again arranged in the studio by an illuminator and adjusted according to its visual perception and according to the instructions from the director.

Als nachteilig wird bei einer derartigen Beleuchtungsanlage insbesondere der hohe Verkabelungsaufwand angesehen. Jeder Leuchtkörper benötigt zu seiner Versorgung drei Leitungsadern, nämlich einen Phasenleiter, einen Nulleiter und einen Schutzleiter, wovon zumindest der Phasenleiter bis zur Schalt- und Dimmeinheit geführt sein muß. Zwischen dem Lichtregelpult und den Schalt- und Dimmeinheiten sind außerdem entweder je Leuchtkörper eine oder zwei Steueradern erforderlich. Der Verkabelungsaufwand addiert sich also mit der Zahl der Leuchtkörper. Zudem stellen die Ummantelungen der vielen und langen Kabel eine hohe Brandlast dar. Bei mobilen Leuchtkörpern, wie an Schienen hängend verfahrbaren Scheinwerfern, muß bei jeder Ortsveränderung des Leuchtkörpers auch dessen zugehörige Verkabelung zumindest teilweise mit dem Leuchtkörper bewegt werden, da deren Zuordnung zueinander festgelegt ist. Dies führt zu einer eingeschränkten Mobilität und geringen Flexibilität beim Einsatz der vorhandenen Leuchtkörper einer Beleuchtungsanlage, was nachteilig eine große Zahl von Leuchtkörpern und damit hohe Investitionen erfordert, um alle Beleuchtungsanforderungen erfüllen zu können.A disadvantage of such a lighting system is the high cabling effort. Each filament requires three line wires for its supply, namely a phase conductor, a neutral conductor and a protective conductor, of which at least the phase conductor must be routed to the switching and dimming unit. Between the light control desk and the switching and dimming units, either one or two control wires are required for each filament. The cabling effort thus adds up to the number of lighting elements. In addition, the sheaths of the many and long cables represent a high fire load. With mobile light fixtures, such as headlights that can be moved on rails, each time the light fixture is moved, its associated cabling must at least partially be moved with the light fixture, since their assignment to one another is fixed. This leads to limited mobility and little flexibility when using the existing lighting fixtures in a lighting system, which disadvantageously requires a large number of lighting fixtures and thus high investments in order to be able to meet all lighting requirements.

Aus der DE 37 19 384 A1 ist ein Leuchtensystem aus frei einstell- und steuerbaren Lichtquellen bekannt, die zum variablen Anstrahlen von Raumobjekten jeweils eine steuerbare Dreh- und Schwenkvorrichtung aufweisen, wobei a) die Lichtquellen aus Leuchten bzw. Strahlern bestehen, die zu einer Gruppe oder mehreren Gruppen zusammengefaßt sind, wobei jeder Strahler zum Einstellen eines frei wählbaren Raumpunktes mit Getriebemotoren und mit einer eigenen elektronischen Datenspeicher- und Steuereinrichtung ausgerüstet ist, die über eine Steuerelektronik durch eine Fernsteuerung programmierbar angesteuert wird und b) die Kommandos zum Einstellen der Strahlerbewegungen der Strahlergruppen von der Fernsteuerung über eine an alle Datenspeicher- und Steuereinrichtungen angeschlossene Steuerleitung erfolgen. Nachteilig ist dieses Leuchtensystem nur für Raumbeleuchtungen insbesondere mit Niedervoltlampen, die ortsfest ein- bzw. angebaut sind, geeignet. Auch ist eine individuelle Steuerung nicht vorgesehen, sondern eine Zusammenfassung von Lichtquellen zu Gruppen. Deshalb ist dieses Leuchtensystem für Film- und Fernsehstudios, Theater, Freilicht- und Konzertbühnen, Mehrzweckhallen, Diskotheken, fliegende Bauten und dergl. mit ihren besonderen Anforderungen nicht einsetzbar.From DE 37 19 384 A1 a lighting system is known from freely adjustable and controllable light sources, each of which has a controllable rotating and swiveling device for the variable illumination of room objects, with a) the light sources consisting of lights or spotlights which form a group or several groups are combined, each radiator for setting a freely selectable point of space is equipped with geared motors and with its own electronic data storage and control device, which is controlled programmably via control electronics by remote control and b) the commands for setting the radiator movements of the radiator groups from the remote control via a control line connected to all data storage and control devices. The disadvantage of this lighting system is that it is only suitable for room lighting, in particular with low-voltage lamps that are installed or installed in a fixed position. Individual control is also not provided, but rather a combination of light sources into groups. For this reason, this lighting system cannot be used for film and television studios, theaters, open-air and concert stages, multi-purpose halls, discotheques, temporary buildings and the like with their special requirements.

Es stellt sich daher die Aufgabe, eine Beleuchtungsanlage der eingangs genannten Art zu schaffen, die für Film- und Fernsehstudios, Theater, Freilicht- und Konzertbühnen und dergl. Großeinrichtungen geeignet ist, bei der der Verkabelungsaufwand und die Brandlast verringert werden können und die eine vergrößerte Flexibilität und Mobilität beim Einsatz der Leuchtkörper der Beleuchtungsanlage bietet.It is therefore the task of creating a lighting system of the type mentioned at the outset, which is suitable for film and television studios, theaters, open-air and concert stages and the like. Large facilities in which the cabling effort and the fire load can be reduced and which increases the size Offers flexibility and mobility when using the illuminants of the lighting system.

Die Lösung dieser Aufgabe gelingt erfindungsgemäß durch eine Beleuchtungsanlage der eingangs genannten Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1.This object is achieved according to the invention by a lighting system of the type mentioned at the outset with the characterizing features of patent claim 1.

Dadurch, daß die Leuchtkörper als mobile, an Schienen frei verfahrbare Einheiten ausgebildet sind, daß die einzelnen Schalt- und Dimmeinheiten jeweils in diese mobilen Einheiten integriert sind und daß die Stromversorgung kabellos über eine Stromschienenanordnung erfolgt, wird eine freie, universelle Verfahrbarkeit, Umsetzbarkeit und Austauschbarkeit der einzelnen Leuchtkörper der Beleuchtungsanlage ermöglicht, ohne daß ein besonderer Aufwand für das Lösen und Wiederherstellen von Leitungsverbindungen nötig ist. Auch die jeweilige funktionale Zuordnung zwischen Leuchtkörper und zugehöriger Schalt- und Dimmeinheit wird dabei nicht beeinflußt, daß jeder Leuchtkörper "seine" Schalt- und Dimmeinheit stets mit sich führt. Es kann also jeder Leuchtkörper an praktisch jede beliebige Stelle eines Schienennetzes für ein oder auch mehrere Studios oder dergl. bewegt werden und dennoch unabhängig von seinem momentanen Aufenthaltsort problemlos angesprochen und in seiner Schalt- und Dimmeinstellung beeinflußt werden. Die neue Beleuchtungsanlage ermöglicht weiter eine wesentliche Verminderung des Verkabelungsaufwandes, da nun alle Leuchtkörper parallel über ihre jeweilige Schalt- und Dimmeinheit mit der gemeinsamen Versorgungs-Stromschienenanordnung, die bevorzugt konstant die Netzspannung von z.B. 220 Volt führt, verbunden sein können. Bei größeren Beleuchtungsanlagen kann diese Stromschienenanordnung auch in mehrere Stromkreise aufgeteilt sein.The fact that the luminous bodies are designed as mobile units that can be moved freely on rails, that the individual switching and dimming units are each integrated in these mobile units, and that the power supply takes place wirelessly via a busbar arrangement, results in free, universal mobility, implementation and interchangeability of the individual illuminants of the lighting system enables, without any special effort for loosening and restoring line connections is necessary. The respective functional assignment between the luminous element and the associated switching and dimming unit is also not affected by the fact that each luminous element always carries "its" switching and dimming unit with it. Every lamp can be moved to practically any point on a rail network for one or more studios or the like, and yet be addressed regardless of its current location without any problems and its switching and dimming settings can be influenced. The new lighting system further enables a significant reduction in the Cabling effort, since now all light fixtures can be connected in parallel via their respective switching and dimming unit to the common supply busbar arrangement, which preferably carries the mains voltage of, for example, 220 volts constantly. In larger lighting systems, this busbar arrangement can also be divided into several circuits.

Eine bevorzugte Weiterbildung sieht vor, daß die Stromschienenanordnung zugleich die Funktion der Tragschienenanordnung für die an ihr hängend verfahrbaren Leuchtkörper übernimmt. Hierdurch wird nur noch ein einziges, einheitliches Schienennetz für das Tragen, Verfahren und Versorgen der Leuchtkörper benötigt.A preferred further development provides that the busbar arrangement at the same time takes over the function of the mounting rail arrangement for the luminous elements which are movable on it. As a result, only a single, uniform rail network is required for carrying, moving and supplying the luminous elements.

Jeder Schalt- und Dimmeinheit individuell zugeführt werden nun lediglich noch die Steuerbefehle, wobei diese Steuerbefehlszuführung, wie in den Ansprüchen 3 und 4 angegeben, bevorzugt auf zwei unterschiedliche Arten erfolgen kann. Da bei diesen Ausführungen der Beleuchtungsanlage die Steuerbefehle über die Stromschienenanordnung für die Leuchtkörper oder über eine drahtlose Übertragungsstrecke zugeführt werden, kann die Beleuchtungsanlage sogar auch ohne Steuerleitungen realisiert werden. Die Auswahl der Art und Weise der Steuerbefehlzuführung richtet sich nach den Umständen des jeweiligen Anwendungsfalles; elektrische oder elektronische Schaltungen und Bausteine für eine Steuerbefehlsübertragung über Leitungen oder drahtlos per Infrarotstrahlung, Laserstrahl, Ultraschall oder Funk sind für sich z.B. aus der Haussicherungs- und Hausleittechnik und Fördertechnik bekannt und können unter entsprechender Anpassung hier eingesetzt werden.Only the control commands are now individually fed to each switching and dimming unit, and this control command supply, as specified in claims 3 and 4, can preferably be carried out in two different ways. Since in these versions of the lighting system the control commands are supplied via the busbar arrangement for the luminaries or via a wireless transmission link, the lighting system can even be implemented without control lines. The selection of the type of control command input depends on the circumstances of the respective application; Electrical or electronic circuits and modules for a control command transmission via cables or wirelessly by infrared radiation, laser beam, ultrasound or radio are for example known from home security and home automation and conveyor technology and can be used here with appropriate adjustment.

Weiter schlägt die Erfindung vor, daß die von der zentralen Regeleinrichtung zu den einzelnen Schalt- und Dimmeinheiten übertragenen Steuerbefehle digitale Signale oder Signalfolgen sind und daß jede Schalt- und Dimmeinheit einen eigenen Empfangsbaustein aufweist. Dies gewährleistet eine hohe Störungsunempfindlichkeit und Sicherheit bei der Steuerbefehlzuführung und ermöglicht eine feine, hochauflösende Regelung der einzelnen Leuchtkörper, die für die praktischen Erfordernisse völlig ausreichend ist und einer stufenlosen analogen Regelung in keiner Weise unterlegen ist. Der Empfangsbaustein kann dabei ein externer oder in die Schalt- und Dimmeinheit integrierter Baustein sein.The invention further proposes that the control commands transmitted from the central control device to the individual switching and dimming units are digital signals or signal sequences and that each switching and dimming unit has its own receiving module. This ensures a high level of immunity to interference and security when the control command is supplied and enables fine, high-resolution control of the individual lighting elements, which is completely sufficient for practical requirements and is in no way inferior to a stepless analog control. The receive module can be an external module or an integrated module in the switching and dimming unit.

Weiterhin ist vorgesehen, daß jedem Empfangsbaustein der Schalt- und Dimmeinheiten eine eigene Adresse zugeordnet ist und daß die digitalen Signale oder Signalfolgen neben den Steuerbefehlen auch Adreßdaten enthalten. Hiermit kann eine große Zahl von Leuchtkörpern individuell angesprochen und geregelt werden, ohne daß eine entsprechende Vergrößerung des Verkabelungsaufwandes auftritt. Die Zahl der ansprechbaren Leuchtkörper richtet sich lediglich nach der Anzahl der für die Adreßdaten zur Verfügung stehenden Bits. Dabei ergibt jedes zusätzliche Bit eine Verdoppelung der ansprechbaren Adressen.It is also provided that each receive module of the switching and dimming units is assigned its own address and that the digital signals or signal sequences contain address data in addition to the control commands. This allows a large number of luminous elements to be addressed and regulated individually without a corresponding increase in the amount of cabling required. The number of addressable light fixtures depends only on the number of bits available for the address data. Each additional bit doubles the addresses that can be addressed.

Um die Arbeit des Beleuchters in einem Studio zu erleichtern und um die bisher erforderliche große Zahl von Potentiometern an einem Lichtregelpult zu reduzieren oder sogar gänzlich überflüssig zu machen, schlägt die Erfindung vor, daß die zentrale Regeleinrichtung einen Digitalrechner mit zumindest einer Eingabe-Einheit aufweist. Außerdem werden hierdurch Automatisierungsmöglichkeiten für die Beleuchtungssteuerung eröffnet, die z.B. zu einem schnelleren Arbeitsablauf bei Film-oder Fernsehproduktionen beitragen können.In order to simplify the work of the lighting technician in a studio and to reduce or even make the large number of potentiometers on a light control panel required to date, the invention proposes that the central control device have a digital computer with at least one input unit. This also opens up automation options for lighting control, e.g. can contribute to a faster workflow in film or television productions.

In weiterer Ausgestaltung der Erfindung umfaßt die zentrale Regeleinrichtung eine Ausgabeeinheit zur Anzeige des jeweiligen Zustandes der einzelnen Leuchtkörper. Neben der optischen Wahrnehmung der Beleuchtungswirkung der Leuchtkörper durch den Beleuchter kann somit auch eine weitere Informationsquelle zur Verfügung gestellt werden, anhand derer eine häufig komplizierte Beleuchtungseinstellung schnell erfaßt, beurteilt und erforderlichenfalls verändert werden kann.In a further embodiment of the invention, the central control device comprises an output unit for displaying the respective state of the individual lighting elements. In addition to the optical perception of the lighting effect of the luminous bodies by the illuminator, a further information source can thus be made available, by means of which a frequently complicated lighting setting can be quickly detected, assessed and, if necessary, changed.

Schließlich ist noch vorgesehen, daß die zentrale Regeleinrichtung eine Speichereinheit zur abrufbaren Speicherung von Schalt- und Dimm-Einstellungen für einzelne Leuchtkörper oder für Gruppen von Leuchtkörpern oder für alle Leuchtkörper umfaßt. Hierdurch wird vorteilhaft die Möglichkeit geschaffen, einmal erarbeitete und bewährte Beleuchtungseinstellungen in digitaler Form zu speichern und bei Bedarf einfach wieder abzurufen und somit eine frühere Beleuchtungseinstellung auch nach längerer Zeit und nach zwischenzeitlichen Änderungen der Einstellungen mit geringem Aufwand und mit hoher Genauigkeit zu reproduzieren.Finally, it is also provided that the central control device comprises a memory unit for the retrievable storage of switching and dimming settings for individual light fixtures or for groups of light fixtures or for all light fixtures. This advantageously creates the possibility of saving once established and proven lighting settings in digital form and simply recalling them when required, and thus reproducing an earlier lighting setting even after a long period of time and after interim changes to the settings with little effort and with high accuracy.

Außer einer wesentlichen Verringerung des Verkabelungsaufwandes bietet die erfindungsgemäße Beleuchtungsanlage noch weitere Vorteile, unter anderem verminderte Hochfrequenz-Störungen, eine verringerte Brandlastgefahr und verringerte Leitungsverluste, die sämtlich infolge der drastischen Leitungsverkürzungen zwischen Schalt-und Dimmeinheit einerseits und Leuchtkörper andererseits erreicht werden. Außerdem können nun Scheinwerfer praktisch beliebig verfahren, ausgetauscht und umgesetzt werden, ohne daß lange Rüstzeiten benötigt werden. Dies schafft z.B. die bisher nicht vorhandene Möglichkeit, einen Leuchtkörper zeitlich kurz nacheinander in mehreren Studios einer Produktionsstätte einzusetzen, so daß insgesamt weniger Leuchtkörper benötigt werden und damit weniger Investitionskosten hierfür anfallen. Auch können aufgrund der schnelleren und genaueren Positionierbarkeit der Leuchtkörper und wegen der dadurch ermöglichten kürzeren Einschaltzeiträume erhebliche Energieeinsparungen von bis zu 30 bis 40% erreicht werden. Die neue Beleuchtungsanlage ist zudem nachträglich problemlos erweiterbar und muß daher nicht von Anfang an in ihrer endgültigen Maximalausführung installiert werden.In addition to a substantial reduction in the cabling effort, the lighting system according to the invention offers further advantages, including reduced high-frequency interference, a reduced risk of fire load and reduced line losses, all of which are achieved as a result of the drastic line shortenings between the switching and dimming unit on the one hand and the luminous element on the other hand. In addition, headlights can now be moved, exchanged and implemented in practically any way without long setup times being required. This creates, for example, the previously non-existent possibility of using a luminous element in succession in several studios of a production facility, so that fewer luminous elements are required overall and therefore less investment costs are incurred for this. Also, due to the faster and more precise positionability of the filament and Because of the shorter switch-on times that this enables, considerable energy savings of up to 30 to 40% can be achieved. The new lighting system can also be easily expanded afterwards and therefore does not have to be installed in its final maximum version from the start.

Im folgenden werden Ausführungsbeispiele der Erfindung anhand einer Zeichnung erläutert. Die Figuren der Zeichnung zeigen jeweils in schematischer Blockdarstellung:

  • Figur 1 eine Beleuchtungsanlage in einer ersten Ausführung,
  • Figur 2 die Beleuchtungsanlage in einer zweiten Ausführung,
  • Figur 3 die Beleuchtungsanlage in einer dritten Ausführung und
  • Figur 4 die Beleuchtungsanlage in einer vierten Ausführung.
Exemplary embodiments of the invention are explained below with reference to a drawing. The figures of the drawing each show a schematic block diagram:
  • FIG. 1 shows a lighting system in a first embodiment,
  • FIG. 2 shows the lighting system in a second embodiment,
  • Figure 3 shows the lighting system in a third embodiment and
  • Figure 4 shows the lighting system in a fourth embodiment.

Figur 1 der Zeichnung zeigt eine erste Beleuchtungsanlage, wobei hier zur Vereinfachung der Darstellung lediglich zwei Leuchtkörper LK1 und LK2 dargestellt sind. In der Praxis ist die Zahl der Leuchtkörper selbstverständlich wesentlich größer. Die Leuchtkörper LK1 und LK2 werden über eine Stromleiteranordnung 10, 11, 12 mit elektrischer Energie, üblicherweise einer Wechselspannung von 220 Volt, versorgt. Bei dem Leiterpaar 10 der Stromleiteranordnung kann es sich beispielsweise um eine Stromschienenanordnung handeln, die zugleich tragende Funktion für die an ihr hängend befestigten Leuchtkörper LK1 und LK2 übernimmt. Die Leiterpaare 11 und 12, die jeweils zu dem Leuchtkörper LK1 bzw. LK2 führen, sind dann z.B. Teil einer Scheinwerferabhängung. Eventuell noch erforderliche Schutzleiter sind hier nicht dargestellt. Die Scheinwerferabhängung kann dabei z.B. ein Verlängerungsarm ("drop arm"), ein Pantograph oder Scherenhänger, ein Teleskop oder dgl. bekanntes Bauteil sein.FIG. 1 of the drawing shows a first lighting system, only two luminous elements LK1 and LK2 being shown here to simplify the illustration. In practice, the number of light bulbs is of course much larger. The luminous elements LK1 and LK2 are supplied with electrical energy, usually an AC voltage of 220 volts, via a current conductor arrangement 10, 11, 12. The pair of conductors 10 of the current conductor arrangement can be, for example, a current rail arrangement which at the same time assumes the supporting function for the luminous elements LK1 and LK2 which are attached to it. The conductor pairs 11 and 12, which each lead to the filament LK1 and LK2, are then e.g. Part of a headlamp suspension. Any protective conductors still required are not shown here. The headlight suspension can e.g. an extension arm ("drop arm"), a pantograph or scissor hanger, a telescope or the like. Known component.

Jedem Leuchtkörper LK1, LK2 ist jeweils ein Empfangsbaustein EB1 bzw. EB2 sowie je eine Schalt- und Dimmeinheit SDE unmittelbar zugeordnet. Mittels der zugehörigen Schalt- und Dimmeinheit ist die Lichtquelle des Leuchtkörpers LK1, LK2 in ihrer Helligkeit regelbar bzw. ein- und ausschaltbar, indem die über die Stromleiteranordnung 10, 11, 12 zugeführte Netzspannung durch die Schalt-und Dimmeinheit SDE entsprechend beeinflußt wird, bevor sie zu der Lichtquelle im Leuchtkörper LK1 bzw. LK2 gelangt. Ihre Steuerbefehle für die jeweils vorzunehmende Einstellung erhalten die Schalt- und Dimmeinheiten SDE von einer zentralen Regeleinrichtung ZRE, von der aus die Regelung sämtlicher Leuchtkörper LK1, LK2 erfolgt. Die zentrale Regeleinrichtung ZRE gibt über eine Steuerleitungsanordnung 20, 21, 22 Steuerbefehle in vorzugsweise digitaler Form aus, die von den jeweils den Leuchtkörpern LK1, LK2 zugeordneten Empfangsbausteinen EB1, EB2 empfangen und an die zugehörige Schalt- und Dimmeinheit SDE weitergegeben werden. Dabei ist vorzugsweise jedem Empfangsbaustein EB1, EB2 eine eigene Adresse zugeordnet, so daß von der zentralen Regeleinrichtung gezielt jeder einzelne Empfangsbaustein EB1, EB2 angesprochen und entsprechend jeder Leuchtkörper LK1, LK2 individuell geregelt werden kann. Für die Steuerbefehlzuführung wird so nur ein Steuerleitungspaar für alle Leuchtkörper LK1, LK2 benötigt.A receiving module EB1 or EB2 and a switching and dimming unit SDE are each directly assigned to each filament LK1, LK2. By means of the associated switching and dimming unit, the brightness of the light source of the luminous element LK1, LK2 can be regulated or switched on and off by the line voltage supplied via the current conductor arrangement 10, 11, 12 being influenced accordingly by the switching and dimming unit SDE before it reaches the light source in the luminous element LK1 or LK2. The control and dimming units SDE receive their control commands for the setting to be made in each case from a central control device ZRE, from which all the luminous elements LK1, LK2 are regulated. The central control device ZRE issues control commands, preferably in digital form, via a control line arrangement 20, 21, 22 which are received by the receive modules EB1, EB2 assigned to the luminous elements LK1, LK2 and passed on to the associated switching and dimming unit SDE. Each receive module EB1, EB2 is preferably assigned its own address, so that the central control device can address each individual receive module EB1, EB2 in a targeted manner and, accordingly, each luminous element LK1, LK2 can be individually controlled. Only one pair of control lines is required for the control command feed for all the luminous elements LK1, LK2.

Als Peripherie der zentralen Regeleinrichtung ZRE ist hier je eine Eingabeeinheit EE, eine Ausgabeeinheit AE und eine Speichereinheit SE vorgesehen. Mittels der Eingabeeinheit, z.B. einer Tastatur, können die benötigten Adressen und Befehle in die zentrale Regeleinrichtung eingegeben werden und von dort nach entsprechender Aufbereitung den Leuchtkörpern LK1, LK2 zugeführt werden. Die Ausgabeeinheit AE kann insbesondere dazu benutzt werden, die aktuellen Einstellungen der einzelnen Leuchtkörper LK1, LK2 anzuzeigen. Die Speichereinheit SE schließlich schafft die Möglichkeit, einmal vorgenommene Beleuchtungseinstellungen in digitaler Form zu speichern und später nach zwischenzeitlicher Änderung der Einstellungen der Leuchtkörper LK1, LK2 problemlos wieder abzurufen und schnell und genau zu reproduzieren.An input unit EE, an output unit AE and a storage unit SE are provided here as the periphery of the central control device ZRE. Using the input unit, e.g. a keyboard, the required addresses and commands can be entered into the central control device and from there, after appropriate preparation, can be fed to the luminous elements LK1, LK2. The output unit AE can in particular be used to display the current settings of the individual luminous elements LK1, LK2. Finally, the memory unit SE creates the possibility of storing lighting settings once made in digital form and, after changing the settings of the luminous elements LK1, LK2 in the meantime, calling them up again without problems and reproducing them quickly and accurately.

Während bei dem Ausführungsbeispiel der Beleuchtungsanlage gemaß Figur 1 für die Übertragung der Steuerbefehle von der zentralen Regeleinrichtung ZRE zu den einzelnen Leuchtkörpern LK1, LK2 noch eine eigene Steuerleitungsanordnung 20, 21, 22 verwendet wird, wird bei dem Ausführungsbeispiel der Beleuchtungsanlage gemäß Figur 2 der Zeichnung die Stromleiteranordnung 10, 11, 12 außer zur Energiezuführung zu den Leuchtkörpern LK1, LK2 auch zur Übertragung der Steuerbefehle genutzt. Die einzelnen Leuchtkörper LK1, LK2 sind, wie auch bei dem zuvor beschriebenen Ausführungsbeispiel, über die Stromleiteranordnung 10, 11, 12 mit elektrischer Energie, z.B. Netzspannung, versorgbar. Auch ist jedem Leuchtkörper LK1, LK2 wieder je ein Empfangsbaustein EB1 bzw. EB2 sowie je eine Schalt- und Dimmeinheit SDE unmittelbar zugeordnet, wobei die Anbringung des Empfangsbausteines EB1 bzw. EB2 sowie der Schalt- und Dimmeinheit SDE beispielsweise im oder am Gehäuse des Leuchtkörpers LK1, LK2 oder auch an dessen Abhängung erfolgen kann.While in the exemplary embodiment of the lighting system according to FIG. 1 a separate control line arrangement 20, 21, 22 is still used for the transmission of the control commands from the central control device ZRE to the individual lighting elements LK1, LK2, in the exemplary embodiment of the lighting system according to FIG Current conductor arrangement 10, 11, 12 is used not only for supplying energy to the luminous elements LK1, LK2, but also for transmitting the control commands. The individual luminous elements LK1, LK2 are, as in the exemplary embodiment described above, via the current conductor arrangement 10, 11, 12 with electrical energy, e.g. Mains voltage, can be supplied. Each lighting element LK1, LK2 is also directly assigned a receiving module EB1 or EB2 and a switching and dimming unit SDE, the attachment of the receiving module EB1 or EB2 and the switching and dimming unit SDE, for example, in or on the housing of the lighting element LK1 , LK2 or also on its suspension.

Auch bei dieser Beleuchtungsanlage ist wieder eine zentrale Regeleinrichtung ZRE mit ihren Peripheriegeräten nämlich Eingabeeinheit EE, Ausgabeeinheit AE und Speichereinheit SE vorgesehen. Über ein erstes Steuerleitungspaar 20 werden die von der zentralen Regeleinrichtung ZRE ausgegebenen Steuerbefehle in die Stromleiteranordnung 10, 11, 12 eingespeist, wobei hier eine kapazitive Einkopplung als Beispiel dargestellt ist. Im Bereich des Leuchtkörpers LK1 werden aus dem zugehörigen Leiterpaar 11 für die Stromversorgung die von der zentralen Regeleinrichtung ZRE in die Stromleiteranordnung 10, 11, 12 eingespeisten Steuerbefehle wieder ausgekoppelt und über ein Steuerleitungspaar 21 dem zum Leuchtkörper LK1 gehörenden Empfangsbaustein EB1 zugeführt. In gleicher Weise werden am Leuchtkörper LK2 Steuersignale aus dem Stromleiterpaar 12 ausgekoppelt und über das Steuerleitungspaar 22 dem zugehörigen Empfangsbaustein EB2 zugeführt. Auf diese Weise gelangen die von der zentralen Regeleinrichtung ZRE ausgegebenen Steuerbefehle parallel zu allen in der Beleuchtungsanlage vorhandenen Empfangsbausteinen EB1, EB2. Aufgrund der in den Steuerbefehlen ebenfalls enthaltenen Adreßinformationen wird ein bestimmter Empfangsbaustein EB1, EB2 angesprochen, der dann den entsprechenden, der Adresse folgenden Steuerbefehl an die Schalt- und Dimmeinheit SDE des betreffenden Leuchtkörpers LK1, LK2 weitergibt.A central control device ZRE with its peripheral devices, namely input unit EE, output unit AE and storage unit SE, is again provided in this lighting system. The central control device ZRE outputs the first control line pair 20 benen control commands fed into the current conductor arrangement 10, 11, 12, wherein a capacitive coupling is shown as an example. In the area of the luminous element LK1, the control commands fed from the central control device ZRE into the current conductor arrangement 10, 11, 12 are coupled out again from the associated conductor pair 11 for the power supply and fed via a pair of control lines 21 to the receiving module EB1 belonging to the luminous element LK1. In the same way, control signals are coupled out of the pair of current conductors 12 on the luminous element LK2 and fed to the associated receive module EB2 via the pair of control lines 22. In this way, the control commands issued by the central control device ZRE arrive in parallel with all of the receive modules EB1, EB2 present in the lighting system. On the basis of the address information also contained in the control commands, a specific receive module EB1, EB2 is addressed, which then forwards the corresponding control command following the address to the switching and dimming unit SDE of the relevant luminous element LK1, LK2.

Bei dem in Figur 3 der Zeichnung gezeigten dritten Ausführungsbeispiel der Beleuchtungsanlage wird eine separate, z.B. für eine Motorenversorgung vorhandene, eine Niedergleich- oder Niederwechselspannung führende Stromleiteranordnung 40 genutzt, die auch in einer Stromschienenanordnung untergebracht sein kann, welche zugleich tragende Funktion für die an ihr hängend befestigte Leuchtkörper LK1 und LK2 übernimmt. Auch im Beispiel gemäß Figur 3 ist eine kapazitive Ein- und Auskopplung als Beispiel dargestellt, wobei hier diese Einkopplung und Auskopplung sowie die Identifizierung, Steuerung und Regelung im übrigen so erfolgt, wie anhand des Beispiels gemäß Figur 2 zuvor beschrieben.In the third exemplary embodiment of the lighting system shown in FIG. 3 of the drawing, a separate, e.g. used for a motor supply, a low-DC or low-AC voltage current conductor arrangement 40 is used, which can also be accommodated in a busbar arrangement, which at the same time takes over the supporting function for the lamps LK1 and LK2 attached to it. A capacitive coupling and decoupling is also shown as an example in the example according to FIG. 3, with this coupling and decoupling as well as the identification, control and regulation being carried out as described previously with reference to the example according to FIG. 2.

Bei dem in Figur 4 der Zeichnung gezeigten vierten Ausführungsbeispiel der Beleuchtungsanlage schließlich wird für die Übertragung der Steuerbefehle keinerlei Leitungsanordnung mehr benötigt, da hier die Übertragung über drahtlose Übertragungsstrecken 31 bzw. 32 erfolgt.Finally, in the fourth exemplary embodiment of the lighting system shown in FIG. 4 of the drawing, no line arrangement is required any longer for the transmission of the control commands, since the transmission takes place here via wireless transmission links 31 or 32.

Die Leuchtkörper LK1 und LK2 sind hier wieder, wie auch zuvor beschrieben, parallel über die Stromleiterpaare 11 und 12 mit der Stromleiteranordnung 10 zwecks Energieversorgung verbunden, so daß an sämtlichen Schalt- und Dimmeinheiten SDE die Netzspannung anliegt. Jeder Leuchtkörper LK1, LK2 und seine zugehörige Schalt- und Dimmeinheit SDE besitzen wieder einen Empfangsbaustein EB1 bzw. EB2.The luminous elements LK1 and LK2 are here again, as also described above, connected in parallel via the conductor pairs 11 and 12 to the conductor arrangement 10 for the purpose of energy supply, so that the mains voltage is present at all switching and dimming units SDE. Each luminous element LK1, LK2 and its associated switching and dimming unit SDE again have a reception module EB1 or EB2.

Auch hier ist wieder eine zentrale Regeleinrichtung ZRE mit zugehöriger Eingabeeinheit EE, Ausgabeeinheit AE und Speichereinheit SE vorgesehen. Die zentrale Regeleinrichtung ZRE gibt hier ihre Steuerbefehle und Adreßinformationen über die drahtlosen Übertragungsstrecken 31, 32 an die entsprechend ausgerüsteten Empfangsbausteine EB1, EB2 weiter. Bei den drahtlosen Übertragungsstrecken 31, 32 kann es sich beispielsweise um Infrarot-, Ultraschall-, Laser-, oder Funk-Übertragungsstrecken handeln.A central control device ZRE with associated input unit EE, output unit AE and memory unit SE is also provided here. The central control device ZRE forwards its control commands and address information via the wireless transmission links 31, 32 to the correspondingly equipped receiving modules EB1, EB2. The wireless transmission links 31, 32 can be, for example, infrared, ultrasound, laser or radio transmission links.
