Description

Technisches GebietTechnical area

Die Erfindung bezieht sich auf das Gebiet der dimmbaren Betriebsgeräte für Lichtquellen, spezifisch auf dimmbare Betriebsgeräte für den kombinierten Betrieb von Gasentladungslampen und Halbleiterlichtquellen.The invention relates to the field of dimmable control gear for light sources, specifically to dimmable control gear for the combined operation of gas discharge lamps and semiconductor light sources.

Stand der TechnikState of the art

Die Erfindung geht aus von dimmbaren Betriebsgeräten für den kombinierten Betrieb von Gasentladungslampen und Halbleiterlichtquellen nach der Gattung des Hauptanspruchs. Bisher wurde bei Leuchten, die neben den seit längeren verwendeten Gasentladunslampen auch Halbleiterlichtquellen wie Leuchtdioden einsetzen, jede Lichtquelle für sich angesehen. Bei dimmbaren Leuchten ist jede Lichtquelle für sich dimmbar, jedoch werden beide Lichtquellen nicht als Einheit angesehen.The invention is based on dimmable operating devices for the combined operation of gas discharge lamps and semiconductor light sources according to the preamble of the main claim. So far, in light fixtures, which also use semiconductor light sources such as light-emitting diodes in addition to the gas discharge lamps that have been used for a long time, every light source has been considered as such. With dimmable lights, each light source is dimmable, but both light sources are not considered as one unit.

Aus der US 7 052 157 B1 ist eine Leuchte bekannt, bei der neben Kompaktleuchtstofflampen auch LEDs zum Einsatz kommen. Die Lichtquellen können unabhängig voneinander gedimmt werden. Ein gemeinsamer Dimmmechanismus, bei dem beide Arten von Lichtquellen zum Einsatz kommen ist hier nicht beschrieben.
WO2006 086967 zeigt ein Gerät nach der Präambel von Anspruch 1From the US Pat. No. 7,052,157 B1 a luminaire is known in which LEDs are used in addition to compact fluorescent lamps. The light sources can be dimmed independently. A common dimming mechanism using both types of light sources is not described here.
WO2006 086967 shows a device according to the preamble of claim 1

Leuchtstofflampen können zwar mit entsprechenden technischen Aufwand bis auf 1% des Nennlichtes gedimmt werden, jedoch sinkt der Wirkungsgrad bei diesen niedrigen Dimmstellungen erheblich. Auch kann sich der Farbort des abgegebenen Lichtes Verändern, da bei sehr niedrigen Leistungen die Lampe stark abkühlt und der Argonentladung gegenüber der Quecksilberentladung mehr Gewicht verleiht.Although fluorescent lamps can be dimmed with the appropriate technical effort to 1% of the nominal light, but the efficiency drops significantly at these low dimming positions. Also, the color of the emitted light can change, as at very low Performs the lamp cools strongly and gives the argon charge over the mercury discharge more weight.

Es ist daher wünschenswert, für sehr niedrige Dimmstellungen eine besser dimmbare Lichtquelle wie z.B. eine Halbleiterlichtquelle vorzusehen. Um die Komplexität der Ansteuerung der beiden Lichtquellen niedrig zu halten, ist es sinnvoll, beide Lichtquellen mit einem Betriebsgerät zu betreiben.It is therefore desirable, for very low dimming positions, to use a more dimmable light source, e.g. to provide a semiconductor light source. In order to keep the complexity of controlling the two light sources low, it makes sense to operate both light sources with one operating device.

Aufgabetask

Es ist Aufgabe der Erfindung, ein dimmbares Betriebsgerät für den kombinierten Betrieb von Gasentladungslampen und Halbleiterlichtquellen zu schaffen, dass eine gemeinsame Dimmsteuerung für beide Lichtquellen beinhaltet, mittels der das von den Leuchtmitteln des Betriebsgerätes abgegebene Licht von einer Nennlichtstärke bis auf 1‰ oder weniger heruntergedimmt werden kann.It is an object of the invention to provide a dimmable operating device for the combined operation of gas discharge lamps and semiconductor light sources, which includes a common dimming control for both light sources, by means of which the output from the lamps of the operating device light from a nominal light intensity down to 1 ‰ or less dimmed can.

Darstellung der ErfindungPresentation of the invention

Die Lösung der Aufgabe erfolgt erfindungsgemäß mit den Merkmalen des Vorrichtungsanspruchs 1 und des Verfahrensanspruchs 10.The object is achieved according to the invention with the features of the device claim 1 and the method claim 10th

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.

Das Betriebsgerät enthält hierzu Schaltungen, die beide Leuchtmittel gedimmt betreiben können. Für die Dimmsteuerung ist ein Eingang vorhanden, der eine Schnittstelle zu einem analogen oder digitalen Lichtsteuerbus darstellen kann. Als analoger Bus wird üblicherweise ein 1-10V-Bus verwendet, als digitale Schnittstelle kommt meistens das DALI-Protokoll zur Verwendung. Die digitale Schnittstelle kennt auch Lichtsteuerbefehle und Lichtszenarien, die im Betriebsgerät abgespeichert werden. Wird ein Signal in diesen Eingang eingegeben, so steuert das Betriebsgerät die Lichtabgabe beider Lichtquellen entsprechend dem eingegebenen Dimmlevel.For this purpose, the operating device contains circuits that can operate both lamps dimmed. For the dimming control there is an input which can be an interface to an analog or digital light control bus. As an analog bus usually a 1-10V bus is used, as a digital interface Mostly the DALI protocol is used. The digital interface also knows light control commands and lighting scenarios that are stored in the operating device. If a signal is input to this input, the operating device controls the light output of both light sources according to the entered dimming level.

Dabei wird je nach Dimmlevel das eine oder das andere Leuchtmittel verwendet, und eine interne Steuerung sorgt dafür, dass der Übergang von einem zum anderen Leuchtmittel dem menschlichen Auge verborgen bleibt. Für einen gewissen Dimmbereich werden beide Leuchtmittel verwendet, um einen sehr sanften Übergang realisieren zu können.Depending on the dimming level, one or the other light source is used, and an internal control ensures that the transition from one light source to the other remains hidden to the human eye. For a certain dimming range, both bulbs are used to realize a very smooth transition.

Bevorzugte Ausführung der ErfindungPreferred embodiment of the invention Erste AusführungsformFirst embodiment

Fig. 1 zeigt ein schematisches Anschlussschema eines erfindungsgemäßen Betriebsgerätes. Das Gerät besitzt Ausgänge für Gasentladungslampen und für Halbleiterlichtquellen. Die Gasentladungslampen sind vorzugsweise Kompaktleuchtstofflampen, und die Halbleiterlichtquellen können z.B. weiß leuchtende LEDs oder OLEDs sein. Es können natürlich auch nur eine Gasentladungslampe und eine Halbleiterlichtquelle oder eine Gasentladungslampe und mehrere Halbleiterlichtquellen verwendet werden. Zusätzlich zum Netzspannungseingang gibt es einen Eingang für eine Lichtsteuerschnittstelle. Diese kann eine digitale oder eine analoge Schnittstelle sein. Es ist aber auch möglich, die Schnittstelle auf das eine oder andere Lichtsteuerprotokoll zu programmieren. Dies hat den Vorteil einer weitestmöglichen Verwendbarkeit des Betriebsgerätes. Fig. 1 shows a schematic connection diagram of an operating device according to the invention. The device has outputs for gas discharge lamps and for semiconductor light sources. The gas discharge lamps are preferably compact fluorescent lamps, and the semiconductor light sources may be, for example, white LEDs or OLEDs. Of course, only one gas discharge lamp and a semiconductor light source or a gas discharge lamp and a plurality of semiconductor light sources may be used. In addition to the mains voltage input, there is an input for a light control interface. This can be a digital or an analog interface. But it is also possible to program the interface to one or the other light control protocol. This has the advantage of the widest possible usability of the operating device.

Die beiden verschiedenen Lichtquellen sollten in der Leuchte so platziert werden, dass die Lichtverteilung beider Leuchtmittel ähnlich ist. Nur so kann die Leuchte ohne sichtbare optische Abweichungen in einem weiten Bereich gedimmt werden.The two different light sources should be placed in the luminaire so that the light distribution of both bulbs is similar. Only then can the luminaire be dimmed within a wide range without visible optical deviations.

Fig. 2 zeigt ein Diagramm, dass die prinzipielle Vorgehensweise beim Übergang von den LEDs auf die Gasentladungslampen verdeutlicht. Es ist die Dimmstellung eines Lichtsteuersignals über die Gesamthelligkeit angegeben. Beide vom Gerät betriebenen Lichtquellenarten werden über ein Lichtsteuersignal angesteuert. Die beiden Kurven für die Halbleiterlichtquellen und die Gasentladungslampen verlaufen in großen Bereichen auf dem Lichtsteuersignal, d.h. dass in allen Bereichen außer dem Dimmbereich von 3%-10% jeweils die Lichtabgabe der Halbleiterlichtquellen oder der Gasentladungslampen dem Vorgabewert des Lichtsteuersignals exakt folgen. Am unteren und oberen Ende endet das Lichtsteuersignal, da es keine Korrelation mehr zwischen Signal und Helligkeit gibt. Im Bereich zwischen 3% bis 10% tragen beide Lichtquellenarten zur Systemlichtabgabe bei. Dabei werden die Lichtquellen jeweils so gedimmt, dass die Gesamtlichtstärke dem Vorgabewert des Lichtsteuersignals entspricht. Fig. 2 shows a diagram that illustrates the basic procedure for the transition from the LEDs to the gas discharge lamps. The dimming position of a light control signal is indicated via the total brightness. Both light source types operated by the device are controlled via a light control signal. The two curves for the semiconductor light sources and the gas discharge lamps run in large areas on the light control signal, ie that in all areas except the dimming range of 3% -10% each of the light output of the semiconductor light sources or the gas discharge lamps exactly follow the default value of the light control signal. At the bottom and top ends the light control signal, as there is no correlation There is more between signal and brightness. In the range of 3% to 10%, both types of light source contribute to system light output. The light sources are each dimmed so that the total light intensity corresponds to the default value of the light control signal.

Die LEDs oder OLEDs leuchten im unteren Dimmbereich, z.B. von 1 ‰ bis 10 %. Ab einer Dimmstellung von 3% werden die Gasentladungslampen dazugeschaltet. Zum Zeitpunkt der Lampenzündung wird Zeitgleich die Lichtleistung der LEDs sprunghaft gesenkt, um die Gesamtlichtstärke der Leuchte nicht zu ändern. Um den kurzen Lichtblitz der Gasentladungslampe, den sie beim Zünden abgibt, möglichst gut zu kompensieren, wäre es auch denkbar die LEDs für den Augenblick der Lampenzündung ganz abzuschalten. Im Bereich zwischen 3% und 10% werden beide Leuchtmittel sukzessive in der Lichtleistung hochgefahren. Bei 10% Dimmstellung werden die LEDs abgeschaltet und die Leistung der Gasentladungslampe sprunghaft angehoben, um wiederum die abgegebene Lichtmenge beizubehalten. Ab da wird die Gasentladungslampe bis zu ihrer Nennleistung heraufgedimmt.The LEDs or OLEDs light in the lower dimming range, e.g. from 1 ‰ to 10%. From a dimming position of 3%, the gas discharge lamps are switched on. At the time of the lamp ignition, the light output of the LEDs is suddenly reduced at the same time so as not to change the total luminous intensity of the lamp. In order to compensate as well as possible for the short flash of light of the gas discharge lamp, which it emits when ignited, it would also be conceivable to completely switch off the LEDs for the moment of the lamp ignition. In the range between 3% and 10%, both lamps are gradually increased in light output. At 10% dimming, the LEDs are turned off and the power of the gas discharge lamp is suddenly increased to maintain the amount of light emitted. From there, the gas discharge lamp is dimmed up to its rated power.

Zweite AusführungsformSecond embodiment

Diese Maßnahmen stellen sicher, dass die Übergänge zwischen den Leuchtmittelkategorien vom menschlichen Auge kaum wahrgenommen werden können. Es besteht aber noch ein Problem hinsichtlich des Farborts des abgestrahlten Lichts. Leuchtstofflampen haben zwar einen definierten Farbort bei Nennleistung, dieser kann sich jedoch je nach Dimmzustand ändern. Vor allem bei niedrigen Dimmstellungen kühlt die Lampe ab. Dies hat zur Folge, dass die Quecksilberentladung zurückgeht, da das Quecksilber an kühlen Stellen der Lampe auskondensiert und somit nicht mehr für die Entladung zur Verfügung steht. Damit erhöht sich aber der Anteil der Argonentladung, was zu einem Abwandern des Farborts ins Rote führt.These measures ensure that the transitions between the categories of lamps can hardly be perceived by the human eye. However, there is still a problem regarding the color location of the emitted light. Although fluorescent lamps have a defined color location at rated power, this can change depending on the dimming condition. Especially at low dimming the lamp cools down. As a result, the Mercury discharge decreases because the mercury condenses in cool places of the lamp and thus is no longer available for the discharge. But this increases the proportion of the Argon charge, which leads to a migration of the color point to the red.

Daher kann der Übergang zwischen den beiden Leuchtmittelkategorien trotz gleicher Helligkeit sichtbar werden. Dies ist vor allem der Fall, wenn die Leuchte längere Zeit im unteren Dimmbereich betrieben wurde, bei dem die Gasentladungslampe stark gedimmt oder ganz abgeschaltet ist. Dann kühlt die Lampe ab und ändert ihre Farbe oder ist beim Start soweit abgekühlt, dass sie eine etwas andere Farbe als im Nennlichtbetrieb abgibt.Therefore, the transition between the two lamp categories can be visible despite the same brightness. This is especially the case when the lamp has been operated for a long time in the lower dimming range, in which the gas discharge lamp is strongly dimmed or completely switched off. Then the lamp cools down and changes its color or is cooled down at the start so far that it gives a slightly different color than in the nominal light mode.

Daher hat das Betriebsgerät in der zweiten Ausführungsform Ausgänge für verschiedenfarbige Leuchtdioden. Bevorzugt gibt es drei Ausgänge für farbig leuchtende Dioden. Diese können dann in roter, grüner und blauer Farbe leuchten, und das Licht aller Halbleiterlichtquellen kann sich so der Lichtfarbe der Gasentladungslampe anpassen.Therefore, the operating device in the second embodiment has outputs for different colored LEDs. There are preferably three outputs for colored LEDs. These can then shine in red, green and blue color, and the light of all semiconductor light sources can adapt to the light color of the gas discharge lamp.

Dazu kann im Betriebsgerät ein Kennfeld eingespeichert sein, das die Abhängigkeit der Temperatur der Gasentladungslampe über die Dimmstellung, die Zeit und den Farbort beschreibt. Bei niedrigen Dimmstellungen, bei denen die Halbleiterlichtquellen eingeschaltet sind, stellt das Betriebsgerät dann den Farbort der verschiedenfarbig leuchtenden Halbleiterlichtquellen auf den Farbort der Gasentladungslampe ein. Die Halbleiterlichtquellen können natürlich in Gruppen organisiert sein, so dass für jede Farbe auch mehrere Halbleiterlichtquellen vorgesehen sind.For this purpose, a map can be stored in the operating device, which describes the dependence of the temperature of the gas discharge lamp on the dimming position, time and color location. At low dimming positions, in which the semiconductor light sources are switched on, the operating device then adjusts the color location of the differently colored semiconductor light sources to the color locus of the gas discharge lamp. Of course, the semiconductor light sources may be organized in groups, so that a plurality of semiconductor light sources are provided for each color.

Eine andere Möglichkeit besteht darin, für die Gesamthelligkeit und den Farbort einen Sensor zu verwenden, und die Lampen so zu steuern, dass die Werte für die Einzelhelligkeiten, für die Gesamthelligkeit und für die beiden Farborte der unterschiedlichen Lichtquellen gemessen und eingeregelt werden können. Dazu müssen die Messungen dann vorgenommen werden, wenn nur das zu messende Leuchtmittel eingeschaltet ist. Dies ist im unteren Dimmbereich relativ einfach, da die Lichtquellen gepulst angesteuert werden und es somit immer Zeitpunkte gibt, in denen nur das zu messende Leuchtmittel leuchtet. Ergibt sich aus der Ansteuerung kein geeigneter Zeitpunkt, so kann die Steuerung des Betriebsgerätes für eine Messung alle nichtzumessenden Leuchtmittel ausschalten. Da dieser Zeitraum sehr kurz ist, kann er vom menschlichem Auge nicht wahrgenommen werden.Another possibility is to use a sensor for the total brightness and the color locus and to control the lamps in such a way that the values for the individual brightnesses, for the total brightness and for the two color locations of the different light sources can be measured and adjusted. For this, the measurements must be made when only the light source to be measured is turned on. This is relatively easy in the lower dimming range, since the light sources are driven pulsed and thus there are always times when only the light source to be measured lights up. If the activation does not result in a suitable time, then the control of the operating device for a measurement can switch off all non-metered lamps. Since this period is very short, it can not be perceived by the human eye.
