Description

Die vorliegende Erfindung betrifft ein Beleuchtungssystem, welches eine Steuereinheit sowie mindestens ein dezentrales Lampenbetriebsgerät zum Betreiben einer Lampe aufweist, wobei das Lampenbetriebsgerät in unterschiedlichen Betriebsmodi betreibbar ist.The present invention relates to a lighting system having a control unit and at least one decentralized lamp operating device for operating a lamp, wherein the lamp operating device is operable in different operating modes.

In größeren Gebäuden kommen oftmals Beleuchtungssysteme zum Einsatz, welche aus mehreren miteinander über ein Busleitungssystem verbundenen Leuchten bestehen. Den Leuchten ist jeweils ein Lampenbetriebsgerät zugeordnet, welches für den Betrieb der zugehörigen Lampe verantwortlich ist. Komplexere Systeme bieten dabei die Möglichkeit, von einer Zentrale aus einzelne Lampenbetriebsgeräte individuell anzusteuern, um bspw. die zugehörigen Leuchten ein- und auszuschalten.In larger buildings often lighting systems are used, which consist of several interconnected via a bus line system lights. The lights are each assigned a lamp operating device, which is responsible for the operation of the associated lamp. In this case, more complex systems offer the possibility of individually controlling individual lamp operating devices from a control center in order, for example, to switch the associated lights on and off.

Neben den reinen Ein- und Ausschaltfunktionen bieten moderne Lampenbetriebsgeräte heutzutage oftmals auch die Möglichkeit, die Lampen in ihrer Helligkeit einzustellen, also zu dimmen. Sollen derartige Geräte in ein größeres Beleuchtungssystem eingebunden werden, so kommen oftmals elektronische Vorschaltgeräte zum Einsatz, welche nach dem sog. DALI (Digital Addressable Lighting Interface) Standard arbeiten. Dieser Standard wurde dazu entwickelt, einzelne Leuchten auf komfortable Weise mittels digitaler Befehle anzusprechen, um sie in ihrer Helligkeit zu verändern.In addition to the pure on and off functions, modern lamp operating devices nowadays also often offer the option of adjusting the brightness of the lamps, ie of dimming them. If such devices are to be integrated into a larger lighting system, so often electronic ballasts are used, which operate according to the so-called. DALI (Digital Addressable Lighting Interface) standard. This standard was developed to address individual luminaires in a comfortable way by means of digital commands in order to change their brightness.

Die zuvor beschriebenen Lampenbetriebsgeräte entsprechend dem DALI-Standard arbeiten auf der einen Seite zwar sehr zufriedenstellend und ermöglichen einen großen Komfort in der Leuchtensteuerung, erfordern allerdings auf der anderen Seite einen verhältnismäßig hohen Investitionsaufwand. Insbesondere für den Fall, dass ein Anwender auch mit rein schaltbaren Leuchten zufrieden wäre, d.h. Leuchten, die er lediglich ein- und ausschalten, nicht aber in ihrer Helligkeit verändern kann, wären die Kosten für die Anschaffung von DALI-Lampenbetriebsgeräten zu hoch.The lamp operating devices described above according to the DALI standard, while working very satisfactorily on the one hand and allow a great comfort in the lighting control, but on the other hand require a relatively high investment cost. In particular, in the event that a user would be satisfied with purely switchable lights, i. Luminaires, which he can only switch on and off, but can not change their brightness, would be too expensive for the purchase of DALI lamp operating devices.

Aus der WO 00/54557 geht ein Gebäudekontrollsystem hervor, welches Lampenbetriebsgeräte und entsprechende Steuergeräte aufweist.From the WO 00/54557 goes out a building control system, which has lamp operating devices and corresponding control devices.

Die vorliegende Erfindung geht nunmehr von der Überlegung aus, dass sich die Bedürfnisse und Anforderungen an ein Beleuchtungssystem im Laufe der Zeit auch ändern können. Beispielsweise können verschiedene Bereiche oder Räume in größeren Gebäuden oftmals von verschiedenen Mietern genutzt werden, deren Wünsche an das entsprechende Beleuchtungssystem sich im Laufe der Zeit ändern, was insbesondere bei einem Mieterwechsel der Fall sein kann. So kann der Fall auftreten, dass ein Nutzer zunächst lediglich mit schaltbaren Leuchten, bei denen keine Dimmfunktion vorhanden ist, zufrieden ist, während hingegen der Nachmieter bereit wäre, auch höhere Kosten in Kauf zu nehmen, um auch die Möglichkeit zu besitzen, Feinabstimmungen in der Helligkeitssteuerung vornehmen zu können. Ein Wechsel von einem Gerätetyp auf einen anderen wäre allerdings selbstverständlich mit einem extrem hohen Kosten- und Arbeitsaufwand verbunden.The present invention now starts from the consideration that the needs and requirements for a lighting system may change over time. For example, different areas or rooms in larger buildings can often be used by different tenants, whose wishes to the corresponding lighting system change over time, especially in a Tenant change may be the case. Thus, the case may arise that a user is initially satisfied only with switchable lights in which no dimming function is present, whereas the new tenant would be willing to accept higher costs in order to also have the opportunity to fine tune in the Brightness control to make. However, a change from one device type to another would of course be associated with an extremely high cost and effort.

Der vorliegenden Erfindung liegt nunmehr die Aufgabe zugrunde, eine Möglichkeit anzugeben, den nutzbaren Funktionsumfang eines Lampenbetriebsgeräts auf möglichst einfache Weise an die individuellen Bedürfnisse eines Nutzers anzupassen.The present invention is based on the object of specifying a way to adapt the usable range of functions of a lamp operating device in the simplest possible way to the individual needs of a user.

Die Aufgabe wird durch ein Beleuchtungssystem, welches die Merkmale des Anspruchs 1 aufweist, gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The object is achieved by a lighting system having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Lösung basiert auf der Idee, grundsätzlich dimmbare Lampenbetriebsgeräte bzw. allgemein Geräte mit einem erweiterten Funktionsumfang zu verwenden, die allerdings je nach den Bedürfnissen des Nutzers derart eingestellt werden können, dass sie für den Nutzer entweder nur schaltbar sind (ein/aus) oder - sofern das Bedürfnis besteht - einen erweiterten Funktionsumfang aufweisen. Der erforderliche Kostenaufwand bei der Verwendung dimmbarer Lampenbetriebsgeräte ist zwar zu Beginn ein höherer, geht man allerdings davon aus, dass zumindest ein Teil der Nutzer im Laufe der Zeit auch die erweiterten Möglichkeiten der Lampenbetriebsgeräte nutzen möchte, so wird sich dieser Kostenaufwand insbesondere unter der Berücksichtigung, dass nunmehr große Umbauarbeiten unter Einsatz neuer Lampenbetriebsgeräte vermieden werden können, amortisieren.The solution according to the invention is based on the idea of basically using dimmable lamp operating devices or general devices with an extended range of functions, which, however, can be adjusted depending on the needs of the user such that they are either only switchable for the user (on / off) or - if the need exists - have an extended range of functions. Although the required cost when using dimmable lamp operating devices is higher at the beginning, it is assumed that at least some of the users would like to use the extended possibilities of the lamp operating devices over the course of time. that now major renovations can be avoided using new lamp operating equipment, amortize.

Gemäß einem ersten Aspekt der vorliegenden Erfindung wird also ein Beleuchtungssystem vorgeschlagen, welches eine Steuereinheit, mindestens ein Lampenbetriebsgerät zum Betreiben einer oder mehrerer Lampen sowie mindestens eine lokalen Steuereinheit aufweist, wobei das Lampenbetriebsgerät in unterschiedlichen Betriebsmodi betreibbar ist. Erfindungsgemäß sind die Steuereinheit und das Lampenbetriebsgerät derart ausgebildet, dass die Auswahl und Einstellung eines Betriebsmodus für das Lampenbetriebsgerät von der oder über die zentrale Steuereinheit durchführbar ist, wobei das Lampenbetriebsgerät dazu ausgebildet ist in Abhängigkeit von dem eingestellten Betriebsmodus von der lokalen Steuereinheit empfangene Befehle in eine entsprechende Ansteuerung der Lampe/n umzusetzen.According to a first aspect of the present invention, therefore, a lighting system is proposed, which has a control unit, at least one lamp operating device for operating one or more lamps and at least one local control unit, wherein the lamp operating device can be operated in different operating modes. According to the invention, the control unit and the lamp operating device are designed such that the selection and adjustment of an operating mode for the lamp operating device from or via the central control unit is feasible, wherein the lamp operating device is configured depending on the set operating mode commands received from the local control unit in a implement appropriate control of the lamp / s.

Insbesondere kann vorgesehen sein, dass die Auswahl und Einstellung eines Betriebsmodus durch die Übermittlung eines entsprechenden Steuerbefehls - beispielsweise über ein Busleitungssystem, welches die Steuereinheit und das Lampenbetriebsgerät verbindet - erfolgt.In particular, it can be provided that the selection and setting of an operating mode by the transmission of a corresponding control command - for example via a bus line system which connects the control unit and the lamp operating device - takes place.

Die Veränderung des nutzbaren Funktionsumfangs des Lampenbetriebsgeräts erfolgt gemäß der vorliegenden Erfindung somit dadurch, dass die entsprechende Funktion bzw. der gewünschte Betriebsmodus an dem Lampenbetriebsgerät durch die zentrale Steuereinheit frei gegeben wird. Sobald dies der Fall ist, kann der Nutzer des Lampenbetriebsgeräts dieses innerhalb des freigeschalteten Funktionsumfangs voll nutzen, so dass diesem - sofern gewünscht - der volle Funktionsumfang zur Verfügung gestellt werden kann. Möchte andererseits ein Nutzer lediglich die Leuchten ein- und ausschalten, so können alle weitergehenden Funktionen und Betriebsmodi des Lampenbetriebsgerätes gesperrt werden, damit sich das Beleuchtungssystem entsprechend den Wünschen des Nutzers verhält. Hierdurch wird somit die Möglichkeit geschaffen, dass bspw. ein Vermieter eines größeren Gebäudes individuell festlegen kann, auf welche Weise die verschiedenen Mieter ihre Leuchten nutzen können. Da bei der Nutzung eines erweiterten Funktionsumfangs höhere Kosten abgerechnet werden können, kann die erhöhte Anfangsinvestition im Laufe der Zeit wieder ausgeglichen werden, da das Freischalten der ergänzenden Betriebsfunktionen sehr einfach durchgeführt werden kann und im Vergleich zu einer Umprogrammierung der Steuergeräte oder sogar zu einem Austausch durch höherwertige Lampenbetriebsgeräte keine Kosten verursacht.The change in the usable functional scope of the lamp operating device is thus carried out according to the present invention in that the corresponding function or the desired operating mode is released on the lamp operating device by the central control unit. As soon as this is the case, the user of the lamp operating device can make full use of this within the unlocked functional scope, so that this - if desired - the full range of functions can be provided. On the other hand, if a user only wants to turn the lights on and off, all other functions and modes of operation of the lamp operating device may be disabled so that the lighting system behaves in accordance with the wishes of the user. This creates the possibility that, for example, a landlord of a larger building can individually set how the different tenants can use their lights. Since higher costs can be charged when using an extended range of functions, the increased initial investment over time can be compensated again, since the release of the supplementary operating functions can be carried out very easily and in comparison to a reprogramming of the ECUs or even to an exchange higher-quality lamp operating devices does not incur any costs.

Anzumerken ist, dass aufgrund der Tatsache, dass die vorgenommenen Einstellungen in den Lampenbetriebsgeräten vermerkt werden, die erfindungsgemäße Lösung die Möglichkeit bietet, einzelne Leuchten individuell in ihrem nutzbaren Funktionsumfang einzustellen, so dass tatsächlich die Möglichkeit besteht, im Rahmen des Beleuchtungssystems verschiedene Leuchten auf verschiedene Weise nutzbar zu machen.It should be noted that due to the fact that the settings made in the lamp operating devices are noted, the solution according to the invention offers the possibility to individually adjust individual lights in their usable range of functions, so that in fact there is the possibility in the context of the lighting system different lights in different ways to make usable.

Die Lampenbetriebsgeräte, welche gemäß der vorliegenden Erfindung in ihrem nutzbaren Funktionsumfang veränderbar sind, sollen vorzugsweise in der Lage sein, entsprechend dem DALI-Standard Steuerbefehle zu erhalten. Um die vorliegende Erfindung auch für solche Geräte nutzbar zu machen, ist eine software-mäßige Änderung in den Lampenbetriebsgeräten dahingehen vorgesehen, dass diese nunmehr einen zusätzlichen Befehl erhalten können, in dem verschiedene Betriebsmodi durch das Steuergerät freigeschaltet oder gesperrt werden können. Die software-mäßige Erweiterung besteht allerdings auch darin, dass je nachdem, ob gewisse Funktionen freigeschaltet sind oder nicht, die DALI-Befehle in bestimmter Weise interpretiert werden. Soll bspw. die Leuchte nur schaltbar sein, so würde ein DALI-Dimmbefehl grundsätzlich als Einschalten interpretiert und lediglich der Abschaltbefehl gemäß dem DALI-Standard als Ausschaltbefehl aufgefasst werden.The lamp operating devices, which are changeable according to the present invention in their usable range of functions, should preferably be able to receive according to the DALI standard control commands. In order to make the present invention also usable for such devices, a software-moderate change in the lamp operating devices is provided that they can now receive an additional command in which different operating modes can be enabled or disabled by the controller. However, the software-based extension also consists in the fact that depending on whether certain functions are enabled or not, interpreted the DALI commands in a certain way become. If, for example, the luminaire can only be switched, then a DALI dimming command would basically be interpreted as switching on and only the switch-off command according to the DALI standard would be interpreted as a switch-off command.

Vorzugsweise ist vorgesehen, dass das Lampenbetriebsgerät die zugeordnete Lampe grundsätzlich im Rahmen einer Basisfunktion betreibt, in dem die Lampe zumindest ein- und ausgeschaltet werden kann. Die Möglichkeit zur Veränderung des Funktionsumfanges des Lampenbetriebsgeräts bzw. zur Einstellung der Betriebsmodi kann dann auch dazu genutzt werden, über einen längeren Zeitraum hinweg eine gleichbleibende Helligkeit der Leuchte sicherzustellen.It is preferably provided that the lamp operating device basically operates the associated lamp as part of a basic function in which the lamp can at least be switched on and off. The possibility of changing the functional scope of the lamp operating device or for setting the operating modes can then also be used to ensure a constant brightness of the lamp over a longer period of time.

In diesem Zusammenhang ist nämlich zu berücksichtigen, dass Leuchten grundsätzlich gesehen im Laufe der Zeit in ihrer Lichtintensität abfallen, was zum einen auf eine Alterung und Abnutzung der Lampe zurückzuführen ist, insbesondere allerdings auch auf einer Verschmutzung der verschiedenen Leuchtenkomponenten, bspw. der Reflektoren oder Abdeckungen beruht.In this context, it must be taken into account that, in principle, luminaires drop in their light intensity over time, which is attributable to aging and wear of the lamp, but in particular also to contamination of the various luminaire components, for example the reflectors or covers based.

Da durch dieses Abnutzungs- und Verschmutzungsphänomen die Nutzbarkeit der Leuchten deutlich beeinträchtigt werden kann, bestehen zwischenzeitlich europaweite Standards, die vorschreiben, dass die Reduzierung der Lichtleistung korrigiert werden muss. Die Norm besagt, dass ein Lichtplaner grundsätzlich berücksichtigen muss, dass die Leuchten in ihrer Lichtleistung im Laufe der Zeit nachlassen und dass dementsprechend von Zeit zu Zeit eine Anpassung bzw. Korrektur oder Reinigung erfolgen muss. Dies ist in der Regel durch ein Wartungspersonal durchzuführen.Since this wear and contamination phenomenon can significantly affect the usability of the luminaires, Europe-wide standards meanwhile stipulate that the reduction in light output must be corrected. The standard states that a lighting designer must always take into account that the luminaires lose their light output over time and that, accordingly, from time to time an adjustment or correction or cleaning must take place. This is usually done by a maintenance staff.

Die ferngesteuerte Veränderung des Funktionsumfangs der Lampenbetriebsgeräte gemäß der vorliegenden Erfindung ermöglicht es nun, diese Nachkorrektur oder Anpassung von einer Zentrale aus vorzunehmen. Es kann bspw. vorgesehen sein, dass das Lampenbetriebsgerät zu Beginn eines Nutzungszeitraums derart eingestellt wird, dass es die Lampe im eingeschalteten Zustand lediglich bei einer Lichtleistung von etwa 80 oder 90 % des verfügbaren Maximalwerts betreibt. Je nach Art des Leuchtentyps und unter Zugrundelegung von Erfahrungswerten wird dann bspw. periodisch in wöchentlichen oder monatlichen Abständen die Ausgangsleistung des Lampenbetriebsgeräts zum Ausgleich des Lichtabfalls angehoben, so dass letztendlich bei einem Einschalten der Leuchte auch über einen längeren Zeitraum hinweg grundsätzlich die gleiche Lichtleistung erzielt wird.The remote-controlled change of the functional range of the lamp operating devices according to the present invention now makes it possible to make this correction or adjustment from a central office. It may, for example, be provided that the lamp operating device is set at the beginning of a period of use such that it operates the lamp in the on state only at a light output of about 80 or 90% of the available maximum value. Depending on the type of luminaire type and on the basis of empirical values, the output power of the lamp operating device is then periodically increased at weekly or monthly intervals to compensate for the light fall, so that, in principle, the same light output is achieved even when the luminaire is switched on for a relatively long period of time ,

Das Anheben kann nunmehr durch die zentrale Steuereinheit erfolgen, welche durch Übermittlung entsprechender Befehle die Basisfunktion derart konfiguriert, dass dem Einschaltbefehl eine entsprechende Ausgangsleistung zugewiesen wird. Diese Lösung bringt darüber hinaus auch noch einen energietechnischen Vorteil mit sich, da letztendlich eine Energieeinsparung erzielt wird.The lifting can now be carried out by the central control unit which, by transmitting corresponding commands, configures the basic function such that the Switch-on command is assigned an appropriate output power. This solution also brings with it an energy advantage with it, since ultimately an energy saving is achieved.

Bislang war es nämlich lediglich bekannt, die Leuchten mit einem überhöhten Anfangswert, bspw. einen um den Faktor 1,2 erhöhten Lichtwert auszugestalten, so dass diese im Laufe der Zeit bei nachlassender Lichtleistung immer noch zumindest die angegebene Solllichtleistung erreichten. Durch die vorliegende Erfindung besteht die Möglichkeit, grundsätzlich Licht mit der gewünschten Lichtleistung abzugeben, darüber hinaus allerdings einen höheren Faktor als Ausgangswert zu benutzen, der durch die niedrigere Ansteuerung ausgeglichen wird. Dies bringt den Vorteil mit sich, dass der Zeitraum, zu dem die Leuchte in ihrer Lichtleistung auf den Sollwert abgefallen ist und damit der Zeitpunkt, zu dem spätestens eine Reinigung durchgeführt werden und evtl. die Lampe gewechselt werden muss, verlängert werden kann. Das heißt, die Wartungszyklen können gemäß der vorliegenden Erfindung verlängert werden, was eine deutliche Kosteneinsparung mit sich bringt, da eine derartige Wartung immer durch den Einsatz menschlicher Arbeitskraft erfolgen müsste, die verhältnismäßig teuer ist.So far, it was only known to design the luminaires with an excessive initial value, for example, a light value increased by a factor of 1.2, so that they still reached at least the stated nominal light output over time as the light output decreased. By means of the present invention, it is possible in principle to emit light with the desired light output, but moreover to use a higher factor than the initial value, which is compensated by the lower activation. This has the advantage that the period in which the luminaire has fallen in its light output to the target value and thus the time at which a cleaning must be carried out at the latest and possibly the lamp must be replaced, can be extended. That is, the maintenance cycles may be lengthened in accordance with the present invention, resulting in significant cost savings since such maintenance would always have to be done by the use of human labor, which is relatively expensive.

Nachfolgend soll die Erfindung anhand der beiliegenden Zeichnung näher erläutert werden. Es zeigen:

Fig. 1 zeigt ein allgemein mit dem Bezugszeichen 1 versehenes Beleuchtungssystem, welches bspw. in einem größeren Bürogebäude oder dergleichen installiert sein kann. Das Beleuchtungssystem 1 ist in mehrere Subsysteme A und B unterteilt, die jeweils für sich ein Beleuchtungssystem gemäß dem DALI-Standard darstellen. Jedes System A und B weist dementsprechend eine lokale Steuereinheit 11 bzw. 21 auf, die über entsprechende Leitungen 10 bzw. 20 mit Leuchensteuergeräten 12-1 bis 12-4 bzw. 22-1 bis 22-4 verbunden sind. Den Lampenbetriebsgeräten sind jeweils entsprechende Lampen LA zugeordnet, die von diesen betrieben werden. Fig. 1 shows a generally provided with the reference numeral 1 lighting system, which can be installed, for example, in a larger office building or the like. The lighting system 1 is subdivided into several subsystems A and B, each of which constitutes an illumination system according to the DALI standard. Every system A and B accordingly has a local control unit 11 or 21, which are connected via respective lines 10 and 20 with light control units 12-1 to 12-4 and 22-1 to 22-4. The lamp operating devices are each associated with corresponding lamps LA, which are operated by them.

Die beiden Subsysteme A und B sind des weiteren über zusätzliche Busleitungen 3 mit einer zentralen Steuereinheit 2 verbunden, welche die zentrale Verwaltung des Gesamtbeleuchtungssystems 1 übernimmt. Die Busleitungen 3 zur Verbindung der Subsysteme A und B mit der zentralen Steuereinrichtung 2 sind nicht notwendigerweise Leitungen, die Bestandteil eines DALI-Systems sind. In der Regel wird es sich vielmehr um andere Leitungen eines allgemeinen Hausleitsystems oder dergleichen handeln.The two subsystems A and B are further connected via additional bus lines 3 with a central control unit 2, which takes over the central management of the overall lighting system 1. The bus lines 3 for connecting the subsystems A and B to the central control device 2 are not necessarily lines that are part of a DALI system. In general, it will rather be other lines of a general home automation system or the like.

Bei den zum Einsatz kommenden Lampenbetriebsgeräten 12 bzw. 22 handelt es sich erfindungsgemäß um Geräte, die verschiedene Funktionen zur Ansteuerung der ihr zugeordneten Lampe LA aufweisen bzw. in unterschiedlichen Betriebsmodi betrieben werden können. Im dargestellten Ausführungsbeispiel, bei dem es sich um Geräte gemäß dem DALI-Standard handelt, können die zugeordneten Lampen LA ein- und ausgeschaltet sowie bei verschiedenen Helligkeitswerten betrieben, also gedimmt werden. Die entsprechenden Steuersignale werden hierzu über die zugeordneten Busleitungen 10 bzw. 20 des jeweiligen Subsystems übermittel, die von dem Benutzer bspw. mit Hilfe eines Tasters oder dergleichen eingegeben werden können. Entsprechende Befehle werden bspw. auch von der zugeordneten lokalen DALI-Steuereinheit 11 bzw. 21 übermittelt.When used for lamp operating devices 12 and 22 are according to the invention to devices that have different functions for controlling the associated lamp LA or can be operated in different operating modes. In the illustrated embodiment, which are devices according to the DALI standard, the associated lamps LA can be switched on and off and operated at different brightness values, that is dimmed. The corresponding control signals are for this purpose transmitted via the associated bus lines 10 and 20 of the respective subsystem, which can be entered by the user, for example. With the help of a button or the like. Corresponding commands are, for example, also transmitted from the assigned local DALI control unit 11 or 21.

In einem Ausgangsstadium ist nun vorgesehen, dass alle Leuchten des Beleuchtungssystems 1 nur im Rahmen einer Basisfunktion arbeiten, bei der lediglich die Möglichkeit besteht, die Lampen LA ein- und auszuschalten. Ein übermittelter Dimmwertbefehl wird in diesem Fall grundsätzlich in ein reines Einschaltsignal umgesetzt, in dem die Leuchte mit der für den Einschaltzustand vorgeschriebenen Leistung betrieben wird.In an initial stage is now provided that all lights of the lighting system 1 only work as part of a basic function in which only the possibility exists, the lamps LA on and off. In this case, a transmitted dimming value command is fundamentally converted into a pure switch-on signal, in which the luminaire is operated with the power prescribed for the switch-on state.

Möchte nun bspw. der Nutzer des Subsystems A die Möglichkeit haben, die Lampen LA auch zu dimmen, so kann er gemäß der vorliegenden Erfindung bei dem Besitzer des Beleuchtungssystems 1 - also z.B. bei dem Vermieter des Gebäudes - hierfür eine Lizenz erwerben. Um dem Benutzer des Subsystems A nunmehr die Möglichkeit zu geben, entsprechend seinem Wunsch die Leuchten LA zu dimmen, wird nunmehr durch die zentrale Steuereinrichtung 2 der entsprechende Betriebsmodus freigeschaltet. Dies erfolgt dadurch, dass den zugehörigen Lampenbetriebsgeräten 12-1 bis 12-4 entsprechende Befehle über die Datenleitungen 2, 10 übermittelt werden, die von diesen intern dazu benutzt werden, die entsprechende Funktion freizuschalten. Die Lampenbetriebsgeräte 12-1 bis 12-4 können hierfür entsprechende Speichereinheiten aufweisen, in denen intern vermerkt wird, welche Funktionen und Betriebsmodi in welcher Weise nutzbar sein sollen. Entsprechend diesen Informationen reagiert dann das Lampenbetriebsgerät 12-1 bis 12-4 auf extern über die Busleitung 10 des DALI-Systems übermittelte Befehle. Im vorliegenden Fall bedeutet dies, dass die Lampenbetriebsgeräte 12-1 bis 12-4 nunmehr DALI-Dimmbefehle in eine entsprechende Ansteuerung der Lampen LA umsetzen und diese nicht nur einschalten.If, for example, the user of the subsystem A now wishes to be able to dimming the lamps LA, then according to the present invention, he can acquire a license from the owner of the lighting system 1-for example, from the landlord of the building. In order to give the user of the subsystem A the opportunity to dim the lights LA according to his desire, the corresponding operating mode is now enabled by the central control device 2. This is done by having the associated Lamp operating devices 12-1 to 12-4 corresponding commands over the data lines 2, 10 are transmitted, which are used internally by them to unlock the corresponding function. The lamp operating devices 12-1 to 12-4 can for this purpose have corresponding memory units in which it is internally noted which functions and operating modes should be usable in which way. According to this information, the lamp operating device 12-1 to 12-4 then responds to commands transmitted externally via the bus line 10 of the DALI system. In the present case, this means that the lamp operating devices 12-1 to 12-4 now implement DALI dimming commands in a corresponding control of the lamps LA and not only turn them on.

Das Freischalten der gewünschten Betriebsmodi in den Lampenbetriebsgeräten 12-1 bis 12-4 erfolgt mittels eines entsprechenden Software-Codes oder Schlüssels, der von den Lampenbetriebsgeräten 12-1 bis 12-4 in geeigneter Weise umgesetzt wird. Dieser Software-Code kann unter anderem auch spezifisch von dem Gerätetyp sowie der Gerätenummer abhängig gemacht werden, so dass ein Missbrauch, also beispielsweise eine unbefugte Nutzung der Dimmfunktionen der Lampenbetriebsgeräte 12-1 bis 12-4 weitestgehend verhindert wird. Um einem Missbrauch weiter vorzubeugen, werden die Lizenzen auch durch die zentrale Steuereinheit 2 verwaltet, in der vermerkt wird, welche Leuchten im Rahmen eines erweiterten Funktionsumfanges genutzt werden können. Auch die lokalen DALI-Steuereinheiten können überwachen, ob die verschiedenen Geräte im Rahmen der erworbenen Lizenzen genutzt werden.The activation of the desired operating modes in the lamp operating devices 12-1 to 12-4 takes place by means of a corresponding software code or key, which is suitably converted by the lamp operating devices 12-1 to 12-4. Among other things, this software code can also be made dependent on the device type and the device number, so that misuse, for example, unauthorized use of the dimming functions of the lamp operating devices 12-1 to 12-4, is largely prevented. In order to further prevent abuse, the licenses are also managed by the central control unit 2, in which it is noted which luminaires can be used within the scope of an extended range of functions. The local DALI control units can also monitor whether the various devices are being used within the scope of the acquired licenses.

Nach Freischaltung der ausgewählten Funktionen kann nun der Benutzer des Subsystems A seine Lampenbetriebsgeräte 12-1 bis 12-4 entsprechend dem erweiterten Funktionsumfang nutzen. Beispielweise besteht für ihn nunmehr die Möglichkeit, die Leuchten auch in gewünschter Weise zu dimmen. Wesentlich hierbei ist, dass hierzu keine Veränderungen der Installationen oder eine von Hand durchzuführende Programmierung der Geräte 12-1 bis 12-4 vorgenommen werden muss. Stattdessen kann die Freigabe der Betriebsmodi in einfacher Weise durch die zentrale Steuereinrichtung 2 erfolgen, weshalb der Aufwand extrem gering ist.After activation of the selected functions, the user of subsystem A can now use his lamp operating devices 12-1 to 12-4 corresponding to the extended range of functions. For example, it is now possible for him to dim the lights in the desired manner. It is essential here that no changes to the installations or a manual programming of the devices 12-1 to 12-4 must be made for this purpose. Instead, the release of the operating modes can be done in a simple manner by the central control device 2, which is why the cost is extremely low.

In gleicher Weise erfolgt dann auch wieder ein Entzug der Dimm-Lizenzen, was bspw. dann erforderlich ist, wenn der Nutzer des entsprechenden Subsystems keine Dimmfunktion mehr wünscht. Durch die zentrale Steuereinrichtung 2 kann dann diese Funktion wiederum gesperrt werden, so dass die Lampenbetriebsgeräte 12-1 bis 12-4 nur in der herkömmlichen Weise, also zum Ein- und Ausschalten der Lampen LA genutzt werden können. Die Lizenzen zur Nutzung der Dimmfunktion können dann bspw. auf andere Leuchten, beispielsweise auf die Leuchten des Subsystems B übertragen werden.In the same way then takes place again a withdrawal of dimming licenses, which, for example, is required if the user of the corresponding subsystem desires no more dimming function. By the central control device 2 then this function can be disabled again, so that the lamp operating devices 12-1 to 12-4 can be used only in the conventional manner, ie for switching on and off the lamps LA. The licenses for using the dimming function can then be transferred, for example, to other lights, such as the lights of the subsystem B.

Wichtig ist, dass nicht alle Lampenbetriebsgeräte eines Subsystems den gleichen nutzbaren Funktionsumfang aufweisen müssen. Selbstverständlich besteht gemäß der vorliegenden Erfindung die Möglichkeit, bei einzelnen Leuchten gezielt die Dimmfunktion frei zu schalten. Darüber hinaus ist anzumerken, dass mit der vorliegenden Erfindung auch die Möglichkeit bestehen würde, andere Funktionen oder Betriebsmodi bei der Ansteuerung von Leuchten gezielt nutzbar zu machen. Beispielsweise könnten auf diese Weise auch Timer-Funktionen, durch die ein automatisches zeitabhängiges Ein- und Ausschalten der Lampen ermöglicht wird, freigeschaltet werden. Auch eine Einstellung der Lampenhelligkeit in Abhängigkeit von Sensorsignalen oder dergleichen könnte auf diese Weise für einen Benutzer nutzbar gemacht werden, so dass dieser entsprechend seinen Wünschen den Komfort der Leuchtensteuerung erweitern bzw. begrenzen kann.It is important that not all lamp operating devices of a subsystem have the same usable functionality. Of course, according to the present invention, it is possible to selectively switch the dimming function for individual luminaires. In addition, it should be noted that with the present invention, it would also be possible to selectively utilize other functions or operating modes in the control of luminaires. For example, timer functions, which enable automatic time-dependent switching on and off of the lamps, could be enabled in this way. An adjustment of the lamp brightness as a function of sensor signals or the like could be made useful for a user in this way, so that it can expand or limit the comfort of the lamp control according to his wishes.

Die ferngesteuerte Freigabe oder Einstellung bestimmter Funktionen und Betriebsmodi für die Lampenbetriebsgeräte 12-1 bis 12-4 bzw. 22-1 bis 22-4 eröffnet darüber hinaus noch eine verbesserte Möglichkeit zu Leuchtenwartung, was nunmehr anhand der Fig. 2a bis 2c erläutert werden soll.The remote release or adjustment of certain functions and operating modes for the lamp operating devices 12-1 to 12-4 or 22-1 to 22-4 also opens up an even better way to lamp maintenance, which is now based on the Fig. 2a to 2c should be explained.

Wie bereits zuvor erläutert wurde, besteht bei Leuchten grundsätzlich das Problem, dass diese im Laufe der Zeit in ihrer Lichtleistung nachlassen. Gründe hierfür können Abnutzungserscheinungen der Lampe sowie Verschmutzungen bestimmter Leuchtenelemente, bspw. der Reflektoren oder dergleichen sein. Da die von der Leuchte abgegebene Lichtleistung niemals unter eine gewünschte Solllichtleistung fallen sollte, ist es üblich, die Leuchten bei ihrer Herstellung derart auszulegen, dass diese zu Beginn ihrer Lebenszeit eine überhöhte Lichtleistung abgeben. Beispielsweise ist es bislang bekannt, im Vergleich zu der Solllichtleistung die Leuchten derart auszulegen, dass sie zu Beginn eine um den Faktor 1,2 erhöhte Lichtleistung abgeben.As has already been explained above, luminaires generally have the problem that they lose their light output over time. Reasons for this can be wear and tear of the lamp as well as contamination of certain lighting elements, eg. The reflectors or the like. Since the light output emitted by the luminaire should never fall below a desired desired luminous power, it is customary to design the luminaires in their manufacture in such a way that they deliver an excessive light output at the beginning of their lifetime. For example, it has hitherto been known to dimension the luminaires in comparison to the nominal luminous power in such a way that at the beginning they emit a light output increased by a factor of 1.2.

Wie in Fig. 2a schematisch dargestellt ist, erzeugt somit eine Leuchte üblicherweise zu Beginn ihrer Lebenszeit eine Lichtleistung E1, die oberhalb der Sollleistung L0 liegt. Im Laufe der Zeit nimmt allerdings diese Leistung aufgrund von Alterungserscheinungen zunehmend ab, bis zu dem Zeitpunkt t1 die Solllichtleistung L0 erzielt wird. Würde die Leuchte nunmehr weiterhin genutzt werden, so würde die abgegebene Lichtleistung unterhalb des Sollwerts fallen, was allerdings nicht zulässig ist. Spätestens zu dem Zeitpunkt t1 ist daher eine Wartung der Leuchte erforderlich, bei der diese bspw. intensiv gereinigt und die Lampe ersetzt wird, so dass ein neuer Zyklus beginnt, bei dem zunächst wiederum eine erhöhte Lichtleistung abgegeben wird, die in der zuvor beschriebenen Weise im Laufe der Zeit wieder abnimmt.As in Fig. 2a is shown schematically, thus generating a light usually at the beginning of their lifetime, a light output E1, which is above the target power L 0 . Over time, however, this power increasingly decreases due to aging phenomena, until the time t 1, the target light power L 0 is achieved. If the luminaire were to continue to be used, the emitted light output would fall below the setpoint, which is not permitted is. At least at the time t 1 , therefore, a maintenance of the lamp is required in which this example. Intensively cleaned and the lamp is replaced, so that a new cycle begins, in which initially an increased light output is delivered, in the manner described above decreases again over time.

Die Ausgangsleistung, also die Lichtleistung, welche die Leuchte zu Beginn eines Wartungsintervalls abgibt, könnte nunmehr erhöht werden. Wie in Fig. 2b dargestellt ist, hat eine höhere Ausgangsleistung E2 zu Beginn eines Wartungsintervalls zur Folge, dass der Zeitpunkt, zu dem die Leuchte aufgrund von Alterungserscheinungen die Solllichtleistung L0 erreicht, hinausgeschoben werden kann. Gemäß der Darstellung in Fig. 2b ist eine erneute Wartung erst zum Zeitpunkt t2 erforderlich, der deutlich nach dem Zeitpunkt t1 liegt.The output power, ie the light output which the luminaire emits at the beginning of a maintenance interval, could now be increased. As in Fig. 2b is shown, a higher output power E 2 at the beginning of a maintenance interval with the consequence that the time at which the lamp reaches the target light output L 0 due to aging phenomena, can be postponed. As shown in Fig. 2b is a renewed maintenance until the time t 2 is required, which is well after the time t 1 .

Die alleinige Erhöhung der Ausgangsleistung bringt allerdings den Nachteil mit sich, dass auch über einen längeren Zeitraum hinweg deutlich mehr Licht abgegeben und damit mehr Energie verbraucht wird, als eigentlich gewünscht ist.However, the sole increase in the output power has the disadvantage that even over a longer period of time emitted significantly more light and thus more energy is consumed than actually desired.

Gemäß einem bevorzugten Ausführungsbeispiel der vorliegenden Erfindung ist nunmehr vorgesehen, dass diese überhöhte Lichtleistung dadurch ausgeglichen wird, dass die Lampe im eingeschalteten Zustand zu Beginn eines Wartungsintervalls bei einer im Vergleich zur Maximalleistung reduzierten Leistung angesteuert wird. Wie in Fig. 2c schematisch dargestellt ist, wird also erfindungsgemäß die Lampenleistung für den Einschaltzustand mit einem reduzierten Faktor F von etwa 80 % eingestellt, wodurch die überhöhte Lichtleistung ausgeglichen wird. Vorzugsweise wird dieser Faktor F derart eingestellt, dass letztendlich im eingeschalteten Zustand zu Beginn des Wartungsintervalls genau die Solllichtleistung L0 erzielt wird.According to a preferred embodiment of the present invention, it is now provided that this excessive light output is compensated by the fact that the lamp is activated in the switched-on state at the beginning of a maintenance interval at a reduced power compared to the maximum power. As in Fig. 2c is shown schematically, the lamp power for the on state is thus set according to the invention with a reduced factor F of about 80%, whereby the excessive light output is compensated. Preferably, this factor F is set such that in the switched-on state at the beginning of the maintenance interval exactly the target light power L 0 is ultimately achieved.

Im Laufe der Nutzungszeit der Leuchte wird dann der Faktor F, also die Ausgangsleistung des Lampenbetriebsgeräts sukzessive angehoben, wobei die Höhe der jeweiligen Anhebung von dem Leuchten- und Lampentyp abhängt. Derartige Erfahrungswerte liegen vor, so dass der Faktor immer derart verändert werden kann, dass er den Abfall in der Lichtleistung, der auf Alterungseffekte zurückzuführen ist, ausgleicht. Letztendlich wird hierdurch erzielt, dass die Leuchte über ihr gesamtes Wartungsintervall hinweg im eingeschalteten Zustand Licht mit der Solllichtleistung L0 abgibt. In Praxis kann dies bei Verwendung von DALI-Lampenbetriebsgeräten dadurch erfolgen, dass für den Einschaltzustand zu Beginn eines Wartungsintervalls ein Dimmwert von beispielsweise 80% vorgegeben wird, der im Laufe der Zeit schrittweise angehoben wird. Der Abfall in der Lichtleitstung der Leuchte wird dann durch die Vorgabe eines höheren Dimmwerts ausgeglichen.In the course of the useful life of the lamp then the factor F, ie the output power of the lamp operating device is successively raised, the height of the respective increase depends on the lamp and lamp type. Such empirical values exist, so that the factor can always be changed in such a way that it compensates for the drop in the light output due to aging effects. Ultimately, this achieves the result that the luminaire emits light with the nominal light power L 0 in its switched-on state over its entire maintenance interval. In practice, this can be done using DALI lamp operating devices in that for the power-on state at the beginning of a maintenance interval, a dimming value of, for example, 80% is given, which is gradually increased over time. The waste in the Lichtleitstung the light is then compensated by the specification of a higher dimming value.

Der besondere Vorteil bei Verwendung des in Fig. 1 dargestellten Beleuchtungssystems besteht darin, dass die Anpassung des Leistungsfaktors F nunmehr durch die zentrale Steuereinrichtung 2 des Beleuchtungssystems erfolgen kann. In dieser 2 Steuereinrichtung sind Informationen hinsichtlich des jeweiligen Lampen- und Leuchtentyps abgelegt, so dass die Steuereinheit 2 in regelmäßigen Abständen, bspw. wochen- oder monatsweise die entsprechenden Lampenbetriebsgeräte auf einen neuen Einschaltpegel umprogrammieren kann.The particular advantage of using the in Fig. 1 illustrated illumination system is that the adaptation of the power factor F can now be done by the central control device 2 of the lighting system. In this 2 control device information is stored with regard to the respective lamp and luminaire type, so that the control unit 2 at regular intervals, for example. Weekly or monthly, the corresponding lamp operating devices can reprogram to a new switch-on.

Dies kann beispielsweise dadurch erfolgen, dass die Steuereinheit 2 in regelmäßigen Abständen die Lampenbetriebsgeräte 12-1 bis 12-4 bzw. 22-1 bis 22-4 kontaktiert, die Dimm-Funktion kurzfristig freigibt und mit Hilfe eines speziellen Befehls einen neuen Helligkeits- bzw. Leistungswert für den Einschaltzustand im Rahmen der Basisfunktion vorschreibt. In einfacher Weise kann hierdurch dauerhaft die gewünschte Lichtleistung für die Leuchte erzielt werden, wobei die für ein Wartungspersonal anfallenden Aufgaben minimal sind.This can be done, for example, by the control unit 2 contacting the lamp operating devices 12-1 to 12-4 or 22-1 to 22-4 at regular intervals, releasing the dimming function at short notice and, with the aid of a special command, setting a new brightness or brightness value Specifies the power value for the switch-on state in the context of the basic function. In a simple manner, the desired light output for the luminaire can thus be achieved permanently, with the tasks arising for a maintenance personnel being minimal.

Anzumerken ist, dass das Anpassen des Lichtabgabefaktors in Abhängigkeit von dem Abnutzungszustand der Leuchte auch für die erweiterte Dimmfunktion dahingehend vorgenommen werden könnte, dass immer der Maximaldimmwert angepasst wird, so dass letztendlich sichergestellt ist, dass über den gesamten Nutzungszeitraum hinweg immer der gleiche Dimmbereich zur Verfügung steht.It should be noted that the adaptation of the light emission factor depending on the wear state of the luminaire could also be made for the extended dimming function in such a way that the maximum dimming value is always adjusted, so that it is ultimately ensured that the same dimming range is always available over the entire period of use stands.

Die vorliegende Erfindung gestattet es somit, auf einfache Weise verschiedene Funktionen für den Benutzer eines Beleuchtungssystems entsprechend seinen Wünschen nutzbar zu machen. Die Möglichkeit der ferngesteuerten Freigabe bestimmter Funktionen sowie Umprogrammierung der Geräte eröffnet darüber hinaus auch die Möglichkeit, bei gleichzeitiger Energieersparnis längere Wartungszeiträume zu realisieren und letztendlich Wartungskosten zu sparen.The present invention thus makes it possible to easily utilize various functions for the user of a lighting system according to his wishes. The possibility of remote release of certain functions and reprogramming of the devices also offers the possibility to realize longer maintenance periods while saving energy and ultimately saving maintenance costs.
