Description

Be s ehre ibung Confession
[1] Betriebsgerät und Verfahren für den kombinierten Betrieb von Gasentladungslampen und Halbleiterlichtquellen.[1] Operating device and method for the combined operation of gas discharge lamps and semiconductor light sources.
Technisches GebietTechnical area
[2] Die Erfindung bezieht sich auf das Gebiet der dimm- baren Betriebsgeräte für Lichtquellen, spezifisch auf dimmbare Betriebsgeräte für den kombinierten Betrieb von Gasentladungslampen und Halbleiterlichtquellen.[2] 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
[3] 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.[3] 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.
[4] Aus der US 7 052 157 Bl ist eine Leuchte bekannt, bei der neben Kompaktleuchtstofflampen auch LEDs zum Ein- satz kommen. Die Lichtquellen können unabhängig voneinander gedimmt werden. Ein gemeinsamer Dimmmechanismus, bei dem beide Arten von Lichtquellen zum Einsatz kommen ist hier nicht beschrieben.[4] US Pat. No. 7,052,187 B1 discloses a luminaire 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.
[5] 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 up 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.
[6] 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 Be¬ triebsgerät zu betreiben.It is therefore desirable to provide a more dimmable light source such as a semiconductor light source for very low dimming positions. In order to keep the complexity of the control of the two light sources low, it makes sense to operate both light sources with a Be ¬ instru-.
Aufgabetask
[7] Es ist Aufgabe der Erfindung, ein dimmbares Be¬ triebsgerät für den kombinierten Betrieb von Gasentla¬ dungslampen und Halbleiterlichtquellen zu schaffen, dass eine gemeinsame Dimmsteuerung für beide Lichtquellen beinhaltet, mittels der das von den Leuchtmitteln des Be- triebsgerätes abgegebene Licht von einer Nennlichtstärke bis auf Vh oder weniger heruntergedimmt werden kann.It is an object of the invention to provide a dimmable Be ¬ instru- for the combined operation of Gasentla ¬ tion lamps and semiconductor light sources, which includes a common dimming control for both light sources, by means of which the light emitted by the lighting means of the operating device of a light Nominal light intensity can be dimmed down to Vh or less.
Darstellung der ErfindungPresentation of the invention
[8] Die Lösung der Aufgabe erfolgt erfindungsgemäß mit den Merkmalen des Vorrichtungsanspruchs 1 und des Verfah- rensanspruchs 10.[8] The object is achieved according to the invention by the features of the device claim 1 and the method claim 10.
[9] Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.[9] Advantageous developments of the invention are specified in the dependent claims.
[10] 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 üblicherwei¬ se ein 1-lOV-Bus verwendet, als digitale Schnittstelle kommt meistens das DALI-Protokoll zur Verwendung. Die di¬ gitale Schnittstelle kennt auch Lichtsteuerbefehle und Lichtszenarien, die im Betriebsgerät abgespeichert wer¬ den. Wird ein Signal in diesen Eingang eingegeben, so steuert das Betriebsgerät die Lichtabgabe beider Licht¬ quellen entsprechend dem eingegebenen Dimmlevel.[10] 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 üblicherwei ¬ se a 1-LOV-bus is used as a digital interface Mostly the DALI protocol is used. The di ¬ gitale interface knows light control commands and light scenarios that are stored in the control gear ¬ to. 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.
[11] Dabei wird je nach Dimmlevel das eine oder das ande¬ re 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 .[11] It is used depending on the dimming level of one or the walls ¬ re lamp, and an internal control ensures that the transition is hidden from one to another lighting means 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
[15] Fig. 1 zeigt ein schematisches Anschlussschema eines erfindungsgemäßen Betriebsgerätes. Das Gerät besitzt Aus¬ gänge für Gasentladungslampen und für Halbleiterlicht- quellen. Die Gasentladungslampen sind vorzugsweise Kompaktleuchtstofflampen, und die Halbleiterlichtquellen können z.B. weiß leuchtende LEDs oder OLEDs sein. Es kön¬ nen 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 Vor¬ teil einer weitestmöglichen Verwendbarkeit des Betriebs¬ gerätes .[1] FIG. 1 shows a schematic connection diagram of an operating device according to the invention. The device features from ¬ transitions for gas discharge lamps and 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. It is of course also possible to use only one gas discharge lamp and one semiconductor light source or one gas discharge lamp and a plurality of semiconductor light sources . 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 pre ¬ part of a widest possible availability of operation ¬ device.
[16] 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.[16] 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.
[17] Fig. 2 zeigt ein Diagramm, dass die prinzipielle Vorgehensweise beim Übergang von den LEDs auf die Gasent¬ ladungslampen 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 Halbleiterlichtquel¬ len 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.[17] Fig. 2 shows a diagram illustrating the principle of the procedure during the transition from the LEDs to the gas- discharge lamps ¬ illustrated. 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 Halbleitlichtquel ¬ len 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.
[18] Die LEDs oder OLEDs leuchten im unteren Dimmbe¬ reich, z.B. von 1 s3 bis 10 %. Ab einer Dimmstellung von 3% werden die Gasentladungslampen dazugeschaltet . Zum Zeitpunkt der Lampenzündung wird Zeitgleich die Licht- leistung der LEDs sprunghaft gesenkt, um die Gesamtlicht¬ stärke der Leuchte nicht zu ändern. Um den kurzen Licht¬ blitz der Gasentladungslampe, den sie beim Zünden abgibt, möglichst gut zu kompensieren, wäre es auch denkbar die LEDs für den Augenblick der Lampenzündung ganz abzuschal- ten. 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 he¬ raufgedimmt .[18] The LEDs or OLEDs illuminate ¬ rich in the lower Dimmbe, for example from 1 to 10% s3. From a dimming position of 3%, the gas discharge lamps are switched on. At the time of lamp ignition, the light output of the LEDs is suddenly reduced at the same time in order not to change the total light intensity of the luminaire. To compensate for the short light ¬ lightning of the gas discharge lamp, which it emits on ignition, as well as possible, it would also be conceivable, the LEDs for the moment of lamp ignition th quite abzuschal-. In the range between 3% and 10% both lamps are successively in the Light power up. 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 up to its rated capacity he raufgedimmt ¬.
Zweite AusführungsformSecond embodiment
[19] 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 Dimmstellun- gen 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 Ab- wandern des Farborts ins Rote führt.[19] These measures ensure that the transitions between categories of light 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 settings, 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. However, this increases the proportion of the argon charge, which leads to a migration of the color locus to the red.
[20] Daher kann der Übergang zwischen den beiden Leuchtmittelkategorien trotz gleicher Helligkeit sichtbar werden. Dies ist vor allem der Fall, wenn die Leuchte länge¬ re Zeit im unteren Dimmbereich betrieben wurde, bei dem die Gasentladungslampe stark gedimmt oder ganz abgeschal¬ tet 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 if the lamp length ¬ re time was operated at low dimmer, which greatly dimmed the gas discharge lamp or completely abgeschal ¬ tet. 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.
[21] Daher hat das Betriebsgerät in der zweiten Ausfüh- rungsform Ausgänge für verschiedenfarbige Leuchtdioden. Bevorzugt gibt es drei Ausgänge für farbig leuchtende Di¬ oden. Diese können dann in roter, grüner und blauer Farbe leuchten, und das Licht aller Halbleiterlichtquellen kann sich so der Lichtfarbe der Gasentladungslampe anpassen.[21] Therefore, in the second embodiment, the operating device has outputs for different colored light emitting diodes. Preferably, there are three outputs for colored luminous Di ¬ oden. 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.
[22] Dazu kann im Betriebsgerät ein Kennfeld eingespei¬ chert sein, das die Abhängigkeit der Temperatur der Gas¬ entladungslampe über die Dimmstellung, die Zeit und den Farbort beschreibt. Bei niedrigen Dimmstellungen, bei de¬ nen 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. [23] Eine andere Möglichkeit besteht darin, für die Ge¬ samthelligkeit und den Farbort einen Sensor zu verwenden, und die Lampen so zu steuern, dass die Werte für die Ein¬ zelhelligkeiten, für die Gesamthelligkeit und für die beiden Farborte der unterschiedlichen Lichtquellen gemessen und eingeregelt werden können. Dazu müssen die Mes¬ sungen dann vorgenommen werden, wenn nur das zu messende Leuchtmittel eingeschaltet ist. Dies ist im unteren Dimm¬ bereich relativ einfach, da die Lichtquellen gepulst an- gesteuert 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. [22] For this purpose, in the operating device, a map may be eingespei ¬ chert, which describes the dependence of the temperature of the gas discharge lamp ¬ on the dimming setting, the time and the color locus. The semiconductor light sources are turned on at low dimming settings in de ¬ nen, is the operating unit then the locus of different brightly colored semiconductor light sources on the color point 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. [23] Another possibility is to use a sensor for the Ge ¬ samthelligkeit and the color locus, and to control the lamps so that the values for the A ¬ zelhelligkeiten, for the total luminance and the two color locations of the different light sources measured and can be regulated. For this, the Mes ¬ solutions must then be carried out only if the measured lamp is turned on. This is relatively easy in the lower dimming ¬ area, since the light sources are pulsed on and controlled it is therefore always points in time in which only the measured lamps illuminated. 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.
