Description

Gebiet der ErfindungField of the invention

Die vorliegende Erfindung bezieht sich allgemein auf das Gebiet der Steuerung von Betriebsparametern von Betriebsgeräten für Leuchtmittel, wie bspw. LED, Gasentladungslampen oder Halogenlampen als. Die Erfindung kann insbesondere Anwendung finden auf dem Gebiet der sog. Retrofit-LED-Lampen, die als Ersatz z.B. von Glühlampen oder Halogenlampen zum Einsatz kommen. Retrofit-Lampen weisen dementsprechend Verbindungs-Sockel auf, mit denen sie in bekannte Lampenfassungen eingebracht, z.B. eingeschraubt oder eingesteckt, werden können.The present invention relates generally to the field of controlling operating parameters of lighting apparatus such as LED, gas discharge lamps or halogen lamps. In particular, the invention can be applied in the field of so-called retrofit LED lamps, which are substituted for e.g. used by incandescent or halogen lamps. Retrofit lamps accordingly have connection pedestals with which they are incorporated into known lamp holders, e.g. screwed or plugged, can be.

Im folgenden wird unter "LED" durchgehend auch "OLED" verstanden.In the following, "LED" is also understood to mean "OLED".

Hintergrund der ErfindungBackground of the invention

Im Folgenden wird die Erfindung vor allem im Hinblick auf Retrofit-Lampen, insbesondere Retrofit-LED-Lampen, beschrieben. Es ist jedoch zu verstehen, dass auch andere, entsprechend ausgestaltete Betriebsgeräte für Leuchtmittel umfasst sein sollen.In the following, the invention is described above all with regard to retrofit lamps, in particular retrofit LED lamps. However, it is to be understood that other, appropriately designed operating devices for lighting means should be included.

Für Retrofit-Lampen ist es wichtig, dass mit ihnen im Wesentlichen die von Glühlampen bekannten Funktionalitäten nachgebildet werden können. Eine dieser bekannten Funktionalitäten ist die Dimmfunktion. Herkömmlicherweise wird ein Dimmen als Phasendimmen ausgeführt, was insbesondere bei Verwendung von Retrofit LED-Lampen verschiedenartige Probleme mit sich bringt.For retrofit lamps, it is important that they essentially reproduce the functionalities known from incandescent lamps. One of these known functionalities is the dimming function. Conventionally, a Dimming is performed as a phase dimming, which brings in particular when using retrofit LED lamps various problems.

Bei gängigen LED-Lampen erfolgt ein Dimmen meist über separate Steuerleitungen durch Übertragung einer Dimm-Information, z.B. eines Dimm-Niveau-Wertes, an die LED-Lampe. Im Retrofit-Bereich ist dies nicht möglich, da bereits die notwendigen Steuerleitungen nicht vorhanden sind, sondern nur eine zweiadrige Verbindung zur Lampe besteht.In common LED lamps, dimming is usually done via separate control lines by transmitting dimming information, e.g. a dimming level value, to the LED lamp. In the retrofit area, this is not possible, since already the necessary control lines are not available, but there is only a two-wire connection to the lamp.

Bekannt sind Lampen, die sich durch bestimmte Ein-/Ausschaltfolgen einer Betriebs- oder Netzspannung in zwei diskrete Leuchtmodi schalten lassen. Eine solche Lampe nach dem Stand der Technik lässt sich durch einfaches Einschalten in einen ersten Leuchtmodus schalten, in dem die Lampe bis zum Ausschalten bei voller Leistung betrieben wird. Durch eine Folge von kurz hintereinander erfolgenden Ein-/Ausschalt-Vorgängen, z.B. Ein-Aus-Ein, kann die Lampe in einen zweiten Leuchtmodus geschaltet werden, in dem die Lampe z.B. mit einer vorbestimmten geringeren Leistung, also gedimmt, betrieben wird. Ein Ausschalten bringt die Lampe wieder in den Ausgangszustand zurück, von dem aus wiederum entweder der erste oder der zweite Leuchtmodus gewählt werden kann.Are known lamps that can be switched by certain on / off sequences of a power or operating voltage in two discrete light modes. Such a lamp according to the prior art can be switched by simply turning it into a first lighting mode, in which the lamp is operated until it is switched off at full power. By a series of successive on / off operations, e.g. On-Off On, the lamp can be switched to a second lighting mode in which the lamp is e.g. is operated with a predetermined lower power, ie dimmed. Switching off brings the lamp back to the initial state, from which again either the first or the second lighting mode can be selected.

Diese Funktionalität ist auch unter dem Begriff "Double Click" bekannt, bei der die Lampe schnelles, wiederholtes (beispielsweise zweifaches) Ein- und Ausschalten der Betriebsspannung als Information, insbesondere als Dimm-Information, auswertet. Bei einem zweifachen schnellen Ein- und Ausschalten der Betriebsspannung wertet die Vorschaltelektronik des Leuchtmittels also dahingehend aus, dass die Lampe mit verringerter Leistung (gedimmt) betrieben wird. Bei den bekannten Lampen stehen aber eben nur zwei vorbestimmte Leuchtmodi zur Verfügung und der Benutzer kann nur zwischen diesen Leuchtmodi wählen (z.B. 100% Leistung oder 80% Leistung). Wird ein Dimmen auf ein anderes Niveau gewünscht, so muss eine andere Lampe gewählt und/oder die Lampe ausgetauscht werden.This functionality is also known by the term "double click", in which the lamp evaluates fast, repeated (for example two times) switching on and off of the operating voltage as information, in particular as dimming information. With a two-fold fast switching on and off of the operating voltage evaluates the ballast electronics of the bulb so to the effect that the lamp with reduced power (dimmed) is operated. In the known lamps, however, only two predetermined light modes are available and the user can only choose between these light modes (eg 100% power or 80% power). If a dimming to another level is desired, then another lamp must be selected and / or the lamp replaced.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es somit, ein alternatives Steuerverfahren für Leuchtmittel wie bspw. für LED-Lampen und insbesondere, aber nicht ausschliesslich, Retrofit LED-Lampen ohne die oben beschriebenen Nachteile bereitzustellen.The object of the invention is thus to provide an alternative control method for lighting means such as, for example, for LED lamps and in particular, but not exclusively, retrofit LED lamps without the disadvantages described above.

This control circuit comprises a microcontroller and / or an application-specific integrated circuit (ASIC) for operating lighting means, such as, for example, one or more LEDs with the inventive method.

The operating device 10 can be separated from the voltage source 2 and connected to it by at least one (one-pole or two-pole) switching element 3. Instead of the lighting means 15, another operating means can also be used which generates an optical or acoustic emission.

Das Betriebsgerät 10 weist ein einen Manipulationssequenz-Detektor 11, z.B. einen Schaltsequenz-Detektor, einen Modulator 12, einen Speicher 13 und einen Leistungswandler 14 auf. Das Leuchtmittel 15 kann entweder direkt oder über Leiter 16 mit dem Betriebsgerät 10 verbunden sein. Die LED 15 wird über den Leistungswandler 14 angesteuert, der hochfrequent getaktet ist.The operating device 10 comprises a manipulation sequence detector 11, e.g. a switching sequence detector, a modulator 12, a memory 13 and a power converter 14. The lighting means 15 can be connected either directly or via conductor 16 to the operating device 10. The LED 15 is driven via the power converter 14, which is clocked at high frequency.

Der Leistungswandler 14 kann durch einen Schaltregler gebildet werden und weist zumindest einen Leistungsschalter auf, der hochfrequent getaktet wird. Bei dem Leistungswandler 14 kann es sich beispielsweise um einen Inverter (Buck-Boost-Konverter), einen Tiefsetzsteller (Buck-Konverter), einen isolierenden Sperrwandler (Flyback-Konverter) oder auch um einen isolierten oder nichtisolierten Halbbrückenwandler handeln.The power converter 14 may be formed by a switching regulator and has at least one power switch, which is clocked at high frequency. The power converter 14 can be, for example, an inverter (buck-boost converter), a buck converter (buck converter), an isolating flyback converter (flyback converter) or else an insulated or non-isolated half-bridge converter.

Der Leistungswandler 14, der schematisch als ein Block dargestellt ist, kann einstufig oder mehrstufig ausgebildet sein. Eine oder mehrere Stufen können mittels jeweils einem oder mehreren Schaltern aktiv von einer oder mehreren Steuerschaltungen getaktet werden. Ein Beispiel für eine mehrstufige Ausgestaltung ist eine zweitstufige Ausgestaltung, bei der die erste Stufe eine aktiv getaktete PFC (Power Facto Correction) Schaltung ist, die eine DC-Ausgangsspannung bereitstellt, die vorzugsweise geregelt ist. Mit der DC-Ausgangsspannung der PFC-Schaltung wird eine zweite Konverterstufe als Zwischenkreisspannung oder Busspannung versorgt, die ein DC/DC-Konverter (bspw. im Falle von LEDs als Leuchtmitteln) oder ein DC/AC-Konverter (bspw. ein Wechselrichter im Falle von Gasentladungslampen) sein kann. Auch die zweite Konverterstufe kann wie gesagt aktiv durch einen oder mehrere Schalter getaktet sein. Bspw. kann die zweite Stufe ein PWM (Impulsbreiten)-Modulator sein.The power converter 14, shown schematically as a block, may be single-stage or multi-stage. One or more stages may be actively clocked by one or more switches by one or more switches. An example of a multi-stage design is a two-stage design in which the first stage is an actively clocked PFC (Power Factor Correction) circuit that provides a DC output voltage, which is preferably regulated. The DC output voltage of the PFC circuit supplies a second converter stage as intermediate circuit voltage or bus voltage, which is a DC / DC converter (for example in the case of LEDs as lamps) or a DC / AC converter (for example an inverter in the case of LEDs) of gas discharge lamps). Likewise, the second converter stage can also be actively clocked by one or more switches. For example. For example, the second stage may be a PWM (Pulse Width) modulator.

Der Manipulationssequenz-Detektor 11 ist dabei dazu eingerichtet, Manipulationssequenzen bzw. Schaltsequenzen, die durch das Ein-/Ausschalten des Schaltelements 3 erzeugt werden, zu erkennen. Der Manipulationssequenz-Detektor 11 überwacht dabei Kriterien wie Zeitkonstanten und/oder Wiederholraten, um verschiedene Sequenzen zu diskriminieren.The manipulation sequence detector 11 is configured to recognize manipulation sequences or switching sequences which are generated by the switching on / off of the switching element 3. The manipulation sequence detector 11 monitors criteria such as time constants and / or repetition rates in order to discriminate different sequences.

Der Manipulationssequenz-Detektor 11 kann mit einer Schaltung kombiniert werden, wie sie bei sog. Notlichtgeräten bereits verwendet wird, um ein im Notlichtfall zu erkennen, das als Versorgungsspannung für das Betriebsgerät nunmehr keine AC-Spannung, sondern eine DC-Spannung anliegt.The manipulation sequence detector 11 can be combined with a circuit that is already used in so-called emergency lighting devices in order to detect an emergency light case, which now has no DC voltage but a DC voltage as the supply voltage for the operating device.

Eine derartige Schaltung ist bekannt aus der DE 10 2007 040555 A1 , deren Offenbarung hiermit durch Bezugnahme übernommen wird.Such a circuit is known from the DE 10 2007 040555 A1 , the disclosure of which is hereby incorporated by reference.

Einerseits kann also eine derartige AC/DC-Erkennungsschaltung verwendet werden, um alleine die Funktion der Detektion der Manipulationssequenz zu implementieren. Als ein Ausführungsbeispiel ist das Betriebsgerät ein Notlichtgerät, bei dem eine AC/DC-Erkennungsschaltung sowohl für die Erkennung der AC/DC-Spannung wie auch zum Erkennen des zeitweisen (nicht durch DC ersetzten) Wegschaltens der AC-Versorgung verwendet wird.On the one hand, therefore, such an AC / DC detection circuit can be used to implement solely the function of detecting the manipulation sequence. As an exemplary embodiment, the operating device is an emergency lighting device in which an AC / DC detection circuit is used both for detecting the AC / DC voltage and for detecting the temporary (not replaced by DC) switching off the AC supply.

Der Manipulationssequenz-Detektor 11 ist mit dem Modulator 12 und dem Speicher 13 verbunden. Der Modulator 12 ist mit dem Speicher 13 und dem Leistungswandler 14 verbunden.The manipulation sequence detector 11 is connected to the modulator 12 and the memory 13. The modulator 12 is connected to the memory 13 and the power converter 14.

Der Modulator 12 ist dazu eingerichtet, einen Betriebsparameter, z.B. eine Spannung, für das Leuchtmittel 15 zwischen einem ersten Wert, z.B. einem ersten Dimm-Niveau, und einem zweiten Wert, z.B. einem zweiten Dimm-Niveau, zu verändern, bzw. den Leistungswandler 14 mit Werten zwischen dem ersten Wert und dem zweiten Wert oder an diesen Werten zu betreiben. Diese Werte werden von dem Leistungswandler 14 derart umgesetzt, dass das an den Leistungswandler 14 angeschlossene Leuchtmittel 15 eine gewünschte Emission, erzeugt, die zwischen oder dem ersten und dem zweiten Wert oder darauf liegt. Insbesondere beeinflußt der Betriebsparameter die Taktung, bspw. die Frequenz oder das Einschaltverhältnis des Leistungswandlers 14.The modulator 12 is adapted to provide an operating parameter, e.g. a voltage for the lighting means 15 between a first value, e.g. a first dimming level, and a second value, e.g. a second dimming level, or to operate the power converter 14 with values between the first value and the second value or at these values. These values are converted by the power converter 14 such that the lighting means 15 connected to the power converter 14 generates a desired emission which lies between or the first and the second value or thereupon. In particular, the operating parameter influences the timing, for example the frequency or the duty cycle of the power converter 14.

Der Betriebsparameter kann im Falle der mehrstufigen Ausgestaltung des Leistungswandlers die Taktung des/der Schalter einer der Stufen oder mehrere Stufen sein. Bspw. kann der Betriebsparameter die Taktung des Schalters einer PFC-Schaltung (als erste oder einzige Stufe) sein, wobei vorzugsweise die Taktung die DC-Ausgangsspannung der PFC-Schaltung verändert, was vorzugsweise einen Einfluss auf die Lichtleistung der Leuchtmittel hat (Dimmen über Amplitude). Diese Dimmbarkeit kann aber auch durch andere Dimmtechniken erreicht oder ggf. mit weiteren Dimmtechniken einer weiteren Stufe kombiniert werden, wie bspw. PWM-Dimmen (vorzugsweise für LEDs) oder ein Dimmen über die Frequenz im Falle eines Halbbrückenwandlers (beispielsweise für LED).The operating parameter, in the case of the multi-stage embodiment of the power converter, the timing of the / the switch be one of the stages or several stages. For example. For example, the operating parameter may be the timing of the switch of a PFC circuit (as first or only stage), wherein preferably the timing changes the DC output voltage of the PFC circuit, which preferably has an influence on the light output of the lamps (dimming over amplitude). However, this dimmability can also be achieved by other dimming techniques or, if appropriate, combined with further dimming techniques of a further stage, such as PWM dimming (preferably for LEDs) or dimming via the frequency in the case of a half-bridge converter (for example for LEDs).

In einer Ausführungsform entspricht der erste Wert 100% der möglichen Emission, also z.B. 100% Lichtemission, und der zweite Wert einem wesentlich geringeren Prozentsatz der möglichen Emission, also z.B. einem Dimmen auf 5% Lichtemission. Es können jedoch für den ersten und den zweiten Wert alle Werte von 0-100% der möglichen Emission gewählt werden.In one embodiment, the first value corresponds to 100% of the possible emission, e.g. 100% light emission, and the second value to a much lower percentage of the possible emission, e.g. a dimming to 5% light emission. However, for the first and second values, all values from 0-100% of the possible emission can be selected.

Es ist zudem möglich, dass der Modulator 12 eine Veränderung der Werte an dem zweiten Wert, also z.B. auf dem zweiten Dimm-Niveau, beginnt.It is also possible for the modulator 12 to detect a change in the values at the second value, e.g. at the second dimming level, begins.

Der Modulator 12 kann weiter dazu eingerichtet sein, den Betriebsparameter zyklisch zwischen dem ersten und dem zweiten Wert zu verändern, wodurch eine kontinuierliche Veränderung der Emission bewirkt wird.The modulator 12 may be further configured to cyclically change the operating parameter between the first and second values, thereby causing a continuous change in emission.

Der Modulator 12 kann weiter dazu eingerichtet sein, den Betriebsparameter zyklisch zwischen dem ersten und dem zweiten Wert zu verändern, wobei am Ende der zyklischen Veränderung, welche auch mehrmals durchlaufen werden kann, wieder der erste Werte erreicht wird. Auf diese Weise kann sichergestellt werden, dass eine ungewolltes oder fehlerhaftes Auslösen der zyklischen Veränderung ohne Einfluß auf den Dauerbetrieb bleibt.The modulator 12 may be further configured to cyclically change the operating parameter between the first and second values, with the first value again being reached at the end of the cyclic change, which may also be repeated several times. This way you can be sure be that an unwanted or faulty triggering of the cyclic change without influence on the continuous operation remains.

Der Speicher 13 ist mit dem Manipulationssequenz-Detektor 11, dem Modulator 12, und dem Leistungswandler 14 verbunden. In ihm kann ein Wert abgespeichert werden, der den aktuellen Wert für den Betriebsparameter angibt, also z.B. ein Dimm-Niveau für ein Leuchtmittel 15. Mit diesem Wert kann festgelegt werden, wie der Leistungswandler 14 das Leuchtmittel 15 betreibt, d.h. welche Emission am Leuchtmittel 15 eingestellt werden soll.The memory 13 is connected to the manipulation sequence detector 11, the modulator 12, and the power converter 14. A value can be stored in it which indicates the current value for the operating parameter, e.g. a dimming level for a lighting means 15. With this value it can be determined how the power converter 14 operates the lighting means 15, i. which emission is to be set on the illuminant 15.

Der Betriebsparameter, der durch die Manipulation der Spannungsversorgung des Betriebsgeräts durch einen Benutzer eingestellt wird, kann auch eine Betriebsartwahl darstellen, so dass aus einer von wenigstens zwei Betriebsarten ausgewählt werden kann. Vorzugsweise sind die mehreren Betriebsarten bereits vorab (bspw. durch den Hersteller) in dem Betriebsgerät abgelegt.The operating parameter set by the manipulation of the power supply of the operating device by a user may also constitute a mode selection so that one of at least two modes of operation may be selected. Preferably, the plurality of operating modes are already stored in advance (for example, by the manufacturer) in the operating device.

Dabei kann eine bspw. vom Hersteller eingestellte Grundeinstellung ("Default Setting") vorliegen, d.h. im Falle eines Standard-Hochlaufs (ohne Betriebsartrwahl durch einen Benutzer) ist das Betriebsgerät (vorzugsweise softwaremässig) bspw. derart konfiguriert, dass es auf einen (Licht)Sensor reagiert ("Sensor Mode"), d.h. abhängig vom Ausgangssignal des Sensors die Betriebsweise der Leuchtmittel verändert, insbesondere deren Helligkeit oder Lichtleistung anpasst.In this case, for example, by the manufacturer set default setting ("Default Setting") are present, i. in the case of a standard run-up (without a user-selected operating mode), the operating device (preferably in terms of software), for example, is configured such that it responds to a (light) sensor ("sensor mode"), ie. Depending on the output signal of the sensor, the mode of operation of the lighting means changed, in particular their brightness or light output adapts.

Wird dagegen durch den Benutzer eine Betriebsartwahl durch eine bestimmte Sequenz (wie beschrieben) durch Spannungsmanipulation generiert, so wechselt das System in einen vom Grundmodus abweichenden Modus, "User Mode" genannt. Dieser User Mode kann eine Betriebsart sein, bei der die Leuchtmittel mit konstanter Leistung betrieben werden.On the other hand, if the user selects a mode of operation by a particular sequence (as described) by voltage manipulation generated, the system changes into a mode deviating from the basic mode, called "User Mode". This user mode can be an operating mode in which the lamps are operated with constant power.

Der Benutzer kann somit zwischen einer Betriebsart, bei der das Betriebsgerät die Leuchtmittel dimmt, und einer Betriebsbart wählen, bei der die Leuchtmittel stets mit konstanter Leistung betrieben werden (englisch "Fixed Output").The user can thus choose between an operating mode in which the operating device dims the lamps, and a operating bit, in which the lamps are always operated at a constant power ("fixed output").

Es kann auch vorgesehen sein, dass der Benutzer durch die genannte Versorgungsspannungs-Manipulation des Betriebsgeräts selektiv bestimmte Betriebsblöcke (z.B. Heizung der Wendeln einer Gasentladungslampe) in einem der Betriebsmodi aktivieren oder deaktivieren kann. Somit können ggf. auch unterschiedliche Energieeffizienzstufen gewählt werden.It may also be contemplated that the user may selectively activate or deactivate certain operating blocks (e.g., heating the filaments of a gas discharge lamp) in one of the operating modes through said supply voltage manipulation of the operating device. Thus, if necessary, different energy efficiency levels can be selected.

Diese Erfindung erlaubt nun z.B. ein dynamisches Dimmen nach folgendem Prinzip (vgl. Fig. 2):
Das Schaltelement 3, z.B. der Netzschalter, wird betätigt um die erfindungsgemäße Lampe bzw. das Betriebsgerät einzuschalten und eine Lichtemission an dem Leuchtmittel hervorzurufen.This invention now allows, for example, a dynamic dimming according to the following principle (see. Fig. 2 ):
The switching element 3, for example, the power switch, is actuated to turn on the lamp or the operating device according to the invention and cause a light emission to the light source.

Dieses Einschalten wird durch den Manipulationssequenz-Detektor 11 erkannt. Erfolgt innerhalb einer bestimmten Zeit nach dem Einschalten der Spannung keine weitere Aktion, wird das Einschalten von dem Manipulationssequenz-Detektor 11 z.B. als normales Einschalten (normal Ein, Fig. 2 oben) erkannt und das Leuchtmittel bei einem vorbestimmten Leistungswert, z.B. 100% Leistung, betrieben. Dies kann z.B. auch so erfolgen, dass in dem Speicher 13 ein bestimmter Standardwert (default) vorliegt, der dem vorbestimmten Leistungswert entspricht.This switching on is detected by the manipulation sequence detector 11. If no further action takes place within a certain time after the voltage has been switched on, the switching on of the manipulation sequence detector 11 becomes, for example, normal switching on (normal on, Fig. 2 above) and the light source is operated at a predetermined power value, eg 100% power. This can eg also be done so that in the memory 13, a certain default value (default) is present, which corresponds to the predetermined power value.

Erfolgt nach dem Einschalten jedoch innerhalb der bestimmten Zeit eine weitere Schaltaktion, z.B. ein weiteres Aus- und Einschalten (Sequenz), so wird dies ebenfalls von dem Manipulationssequenz-Detektor 11 erkannt und als Anweisung interpretiert, in einen Dimm-Modus zu wechseln. Detektiert der Manipulationssequenz-Detektor 11 die Anweisung in den Dimm-Modus zu wechseln, so weist er den Modulator 12 an, den Leistungswandler 14 mit Werten zwischen dem ersten und dem zweiten Dimm-Niveau zyklisch zu steuern. Dies hat zur Folge, dass die Lichtemission am Leuchtmittel kontinuierlich verändert wird (Aufwärts- und Abwärtsdimmen).However, after switching on, within the specified time, another switching action, e.g. another switching on and off (sequence), this is also detected by the manipulation sequence detector 11 and interpreted as an instruction to switch to a dimming mode. If the manipulation sequence detector 11 detects the instruction to change to the dimming mode, it instructs the modulator 12 to cyclically control the power converter 14 with values between the first and the second dimming level. This has the consequence that the light emission at the light source is changed continuously (upward and downward dimming).

Typische Zeitkonstanten für die Abwärts- oder Aufwärtsdimmflanke liegen im Bereich von einigen Sekunden, also beispielsweise 2 bis 10 Sekunden.Typical time constants for the downward or upward dimming flank are in the range of a few seconds, for example 2 to 10 seconds.

Die vorbestimmte Zeit kann dabei ein Schwellwert sein, der normalerweise deutlich unter einer Sekunde liegt. Das Betriebsgerät wird also nach dem schnellen Wiedereinschalten zyklisch von dem Nennwert 100% herabdimmen auf einen Minimal-Dimmwert von beispielsweise 5%, um dann wieder aufwärts zu dimmen (siehe Fig. 2 unten).The predetermined time may be a threshold, which is usually well below one second. Thus, after the quick restart, the operating device cyclically dimming from the nominal value 100% to a minimum dimming value of, for example, 5% and then dimming again upwards (see FIG Fig. 2 below).

Dieses zyklische Abwärts- und Aufwärtsdimmen wird wiederholt, bis der Benutzer manuell durch erneutes schnelles Aus- und Einschalten (Sequenz) der Spannungsversorgung den aktuellen Wert festlegt, sozusagen einfriert.This cyclic downward and upward dimming is repeated until the user manually sets the actual value manually by renewed rapid switching off and on (sequence) of the voltage supply, so to speak, freezes.

Dabei wird von dem Manipulationssequenz-Detektor 11 eine weitere Schaltsequenz detektiert. Daraufhin wird der momentane Modulationswert in dem Speicher 13 abgelegt und das Leuchtmittel wird von dem Leistungswandler 14 mit dem Modulationswert betrieben, bei entsprechend reduzierter Lichtemission. Die weitere Aus-/Einschaltsequenz kann der ersten Schaltsequenz entsprechen oder davon verschieden sein.In this case, a further switching sequence is detected by the manipulation sequence detector 11. Subsequently, the instantaneous modulation value is stored in the memory 13 and the light source is operated by the power converter 14 with the modulation value, with correspondingly reduced light emission. The further off / on sequence may correspond to or be different from the first switching sequence.

Nach einem Ausschalten der Spannung für einen weiteren vorbestimmten Zeitraum wird in einer Ausführungsform das Betriebsgerät wieder in einen Ausgangszustand zurück gesetzt (im Speicher 13 wird z.B. der Standardwert (default) gesetzt).After switching off the voltage for a further predetermined period of time, in one embodiment the operating device is reset to an initial state (in memory 13, for example, the default value is set).

Der Speicher 13 kann auch außerhalb des Betriebsgerätes 10 angeordnet sein. Beispielsweise kann das Betriebsgerät 10 über eine Schnittstelle mit dem außerhalb des Betriebsgerätes 10 angeordnetem Speicher 13 verbunden sein. Somit kann es auch möglich sein, dass bei Austausch des Betriebsgerätes 10 der Speicher 13 mit dem neu eingesetzten Betriebsgerät verbunden wird und der im Speicher 13 abgelegte Modulationswert an das neu eingesetzte Betriebsgerät zurück übertragen wird. Der Speicher 13 kann beispielsweise in einem mit dem Betriebsgerät 10 verbundenen Sensor angeordnet sein.The memory 13 may also be arranged outside of the operating device 10. For example, the operating device 10 may be connected via an interface with the memory 13 arranged outside the operating device 10. Thus, it may also be possible that when replacing the operating device 10, the memory 13 is connected to the newly inserted operating device and the stored in the memory 13 modulation value is transmitted back to the newly used operating device. The memory 13 may be arranged, for example, in a sensor connected to the operating device 10.

Wenn ein Sensor an das Betriebsgerät 10 angeschlossen ist und ein Speicher 13 vorhanden ist, dann können in dem Speicher 13 auch für verschiedene Sensorwerte wie bspw. Helligkeitswerte im Falle eines Lichtsensors unterschiedliche Modulationswert abgelegt oder auch programmiert werden. Somit können gemäß einer Ausführungsform auch bei verschiedenen Sensorwerten (bspw. Helligkeitswerten) durch das erfindungsgemäße Verfahren (d.h. eine Manipulationssequenz) unterschiedliche Modulationswerte in dem Speicher abgelegt werden und diese als eine Art Referenztabelle den jeweiligen Modulationswert für den Leistungswandler 14 vorgeben.If a sensor is connected to the operating device 10 and a memory 13 is present, different modulation values can also be stored or also programmed in the memory 13 for different sensor values such as, for example, brightness values in the case of a light sensor. Thus, according to one embodiment, different values of the sensor (for example brightness values) can also be different by the method according to the invention (ie a manipulation sequence) Modulation values are stored in the memory and these specify as a kind of reference table the respective modulation value for the power converter 14.

Es kann aber auch vorgesehen sein, den Ausganszustand durch Ausführen einer Rücksetzsequenz wieder herzustellen. So kann der festgelegte Betriebsparameterwert (z.B. das Dimm-Niveau) auch über ein normales Ausschalten (normal Aus) hinaus gehalten werden. Erst nach ausführen der Rücksetzsequenz wird dann der Ausgangszustand wieder hergestellt.But it can also be provided to restore the Ausganszustand by executing a reset sequence. Thus, the set operating parameter value (e.g., the dimming level) may also be kept above a normal off (normal off). Only after executing the reset sequence is the initial state restored.

Die Erfindung ist von der Switch-Dim (TRIDONIC®) oder Touch-Dim Technologie dadurch abzugrenzen, dass die Information, d.h. das manuelle Betätigen eines Schalters, unmittelbar über die Spannungsversorgung erfolgt. Bei Touch-Dim- bzw. Switch-Dim wird die Dimm-Informationen vorzugsweise von einem Taster oder Schalter über einen Signaleingang der Betriebsvorrichtung zugeführt (die eigentliche Spannungsversorgung ist unabhängig davon).The invention is to be distinguished from the Switch-Dim (TRIDONIC®) or Touch-Dim technology in that the information, i. the manual actuation of a switch takes place directly via the power supply. In the case of touch dim or switch dim, the dimming information is preferably supplied from a pushbutton or switch via a signal input of the operating device (the actual voltage supply is independent of this).

Die zur Verwirklichung der Erfindung benötigte Elektronik, die das schnelle Ein- und Ausschalten von dem normalen Ein- und Ausschaltvorgang diskriminiert, ist vorzugsweise im Sockelbereich des Lampe (bzw. der Retrofit LED-Lampe) untergebracht.The electronics required for the implementation of the invention, which discriminates the rapid switching on and off of the normal switching on and off, is preferably housed in the base region of the lamp (or the retrofit LED lamp).

Weiter kann ein Energiepuffer vorgesehen sein, beispielsweise ein Kondensator, der zumindest einen "Netzausfall", ein Ausschalten, im Bereich des schnellen Ein-/Ausschaltens überbrückt, so dass die Elektronik die Schaltsequenz auswerten kann.Furthermore, an energy buffer can be provided, for example a capacitor which bridges at least one "power failure", a switch-off, in the area of rapid on / off switching, so that the electronics can evaluate the switching sequence.

Somit kann der Benutzer zu dem Zeitpunkt, zu dem eine von ihm gewünschte Dimm-Einstellung vorliegt, diese Einstellung durch Ausführen der zweiten Schaltsequenz festlegen.Thus, the user can set this setting by executing the second switching sequence at the time when a dimming setting desired by him is present.

Die sensorische Wiedergabe muss nicht zwangsweise durch die Leuchtmittel selbst erfolgen (Farbtemperaturveränderung, Dimmen, etc.), sondern kann auch durch andere Elemente (weitere optische Elemente, akustische Elemente, etc.) erfolgen.The sensory reproduction does not necessarily have to be done by the lamps themselves (color temperature change, dimming, etc.), but can also be done by other elements (other optical elements, acoustic elements, etc.).

Es können also unterschiedliche Betriebsparameterveränderungen durch Manipulationen der Spannungsversorgung erfolgen, wobei diese beispielsweise anhand unterschiedlicher Manipulationskriterien (Manipulations- oder Schaltsequenzen) diskriminiert werden können.Thus, different operating parameter changes can take place by manipulations of the voltage supply, wherein these can be discriminated, for example, on the basis of different manipulation criteria (manipulation or switching sequences).

Alternativ können sich auch unterschiedliche Betriebsparameterveränderungen zyklisch abwechseln, so dass beispielsweise ein erste Manipulationssequenz (Double Click) eine zyklische erste Betriebsparameterveränderung, z.B. eine Dimmwert-Veränderung, auslöst, die dann abgelöst wird von einer zweiten Betriebsparameterveränderung, z.B. einer Farbortveränderung bei dem nächsten Double Click, etc.Alternatively, also different operating parameter changes can alternate cyclically, so that, for example, a first manipulation sequence (double-click) changes a cyclic first operating parameter change, e.g. a dimming value change, which is then replaced by a second operating parameter change, e.g. a color location change in the next double click, etc.

Weiter ist es möglich, einen anderen Betriebsmodus, z.B. den Dimm-Modus, aus dem eingeschalteten Zustand heraus durch eine Manipulationssequenz (z.B. Aus-Ein oder Aus-Ein-Aus-Ein in schneller Folge, d.h. innerhalb einer vorgegebenen Zeitspanne) zu wählen.Further, it is possible to use another mode of operation, e.g. the dimming mode to be selected from the on state by a manipulation sequence (e.g., off-on or off-on-off on, in rapid succession, i.e. within a predetermined period of time).

Besonders bei einem Einsatz mehrerer Lampen an einer Spannungsversorgung ist es wichtig, dass alle Lampen mit gleichen Modulationswerten, z.B. auf dem gleichen Dimm-Niveau, betrieben werden, d.h. einen gleichen (Licht)Emissionswert aufweisen. Normalerweise werden unterschiedliche Lampen eine zufällig verteilte und somit auch unterschiedliche Zeitbasis haben. Damit verhalten sich die Leuchtmittel in der Modulationsphase unterschiedlich, wodurch sich ein uneinheitliches Lichtbild ergibt.Especially when using several lamps on a power supply, it is important that all lamps are operated with the same modulation values, eg at the same dimming level, ie an equal (light) emission value respectively. Normally different lamps will have a randomly distributed and therefore different time base. Thus, the bulbs behave differently in the modulation phase, resulting in a non-uniform light image.

Gemäß der Erfindung erfolgt nunmehr jegliche Betriebsparameterveränderung (beispielsweise das Abwärts/Aufwärtsdimmen) unter Verwendung einer Wechselspannung, z.B. der Netzspannung, als Zeitbasis. Vorzugsweise sind dabei die Nulldurchgänge der Spannung die zur Synchronisierung der Betriebsparameterveränderung verwendete Zeitbasis.According to the invention, any change in operating parameters (for example, down / up dimming) now takes place using an AC voltage, e.g. the mains voltage, as a time base. Preferably, the zero crossings of the voltage are the time base used to synchronize the operating parameter change.

Genauer gesagt wird der Gradient und somit auch die Zeitdauer zwischen den einzustellenden Betriebsparameterwerten, bzw. den Dimm-Niveaus, auf eine vorbestimmte Anzahl von Spannungszyklen definiert, und nicht über eine absolute Zeitdauer wie beispielsweise "10 Sekunden". Dies ist in Fig. 3 veranschaulicht. Im oberen Teil von Fig. 3 sind Spannungszyklen dargestellt. Im unteren Teil der Fig. 3 ist dargestellt, wie die Betriebsparameterveränderung (Abwärts- und Aufwärtsdimmschritte) abhängig von den Spannungszyklen erzeugt wird.More specifically, the gradient and thus also the time duration between the operating parameter values to be set, or the dimming levels, is defined to a predetermined number of voltage cycles, and not over an absolute time duration such as "10 seconds". This is in Fig. 3 illustrated. In the upper part of Fig. 3 Voltage cycles are shown. In the lower part of the Fig. 3 Fig. 2 shows how the operating parameter change (down and up dimming steps) is generated depending on the voltage cycles.

Wie bereits erwähnt wurde die Erfindung vor allem im Hinblick auf LED-Lampen, insbesondere Retrofit LED-Lampen, beschrieben. Es ist jedoch zu verstehen, dass die Erfindung auch für entsprechend ausgestaltete Betriebsgeräte für andere Leuchtmittel angewendet werden kann.As already mentioned, the invention has been described above all with regard to LED lamps, in particular retrofit LED lamps. However, it is to be understood that the invention can also be applied to appropriately designed operating devices for other lamps.
