Description

Die Erfindung betrifft eine Schaltungsanordnung zur energieoptimalen Helligkeitssteuerung von Gasentladungslampen. The invention relates to a circuit arrangement for energy-optimal brightness control of gas discharge lamps.

Eine Schaltungsanordnung der eingangs genannten Art besteht grundsätzlich aus einer Blindleistungskompensationsschaltung und einem Gleichrichter, welche entsprechend des angeschlossenen Netzes ein- oder mehrphasig ausgelegt sind, einem Gleichspannungszwischenkreis, einem Wechselrichter, welcher in Brücken- oder Mittelpunktschaltung ausgeführt ist, einer der Wechselrichterleistung angepassten Anzahl von Gasentladungslampen mit Vorschaltdrossel und ohne Parallelkondensator, sowie einer übergeordneten Ansteuerung, welche mit den vorgenannten Baugruppen Messwerte und Ansteuerdaten austauscht. A circuit arrangement of the aforementioned type basically consists of a reactive power compensation circuit and a rectifier, which are designed according to the connected network one or more phases, a DC voltage intermediate circuit, an inverter, which is designed in bridge or mid-point, adapted to the inverter power number of gas discharge lamps Ballast choke and without parallel capacitor, as well as a higher-level drive, which exchanges measured values and control data with the aforementioned modules.

Bisher bekannt Schaltungsanordnungen zum Dimmen von Gasentladungslampen arbeiten am Wechselrichterausgang mit Reihenschwingkreisen ( DE 40 18 127 A1 , DE 40 39 161 A1 , DE 197 15 342 C1 ), was den Hardwareaufwand vergrößert und die Ansteuerung unnötig verkompliziert. Heretofore known circuit arrangements for dimming gas discharge lamps operate at the inverter output with series resonant circuits ( DE 40 18 127 A1 . DE 40 39 161 A1 . DE 197 15 342 C1 ), which increases the hardware complexity and unnecessarily complicates the control.

Die DE 600 24 215 T2 beschreibt ein modulares Hochfrequenz-Vorschaltgerät für Fluoreszenzlampen. Um elektromagnetische Störungen bei anderen elektrischen Geräten, die durch die Welligkeit und Spitzen eines hochfrequenten Ausgangstromes hervorgerufen werden, zu vermindern, wird ein Pufferkondensator der Gleichspannungsquelle eingesetzt. The DE 600 24 215 T2 describes a modular high-frequency ballast for fluorescent lamps. In order to reduce electromagnetic interference in other electrical devices caused by the ripples and peaks of a high-frequency output current, a buffer capacitor of the DC voltage source is used.

In der DE 41 23 187 A1 wird ein Vorschaltgerät zum Pulsbetrieb von Gasentladungslampen gezeigt, welches eine selbstschwingende oder fremdgesteuerte Halb- oder Vollbrückenschaltung anwendet. Durch Vorschaltgerät und Brückenschaltung wird die Zündung und Helligkeitsregelung der Gasentladungslampen geregelt. Weiterhin kann darüber die Farbtemperatur oder die Lichtausbeute reguliert werden. In the DE 41 23 187 A1 a ballast for pulsed operation of gas discharge lamps is shown, which applies a self-oscillating or externally controlled half or full bridge circuit. The ballast and bridge circuit regulate the ignition and brightness control of the gas discharge lamps. Furthermore, the color temperature or the luminous efficacy can be regulated.

Die US 5,471,116 A beschreibt eine allgemeine Baugruppe zur Steuerung der Lichtintensität einer Gasentladungslampe. Dazu wird eine Hochspannung initiiert, mittels der die Gasentladungslampe gedimmt wird. The US 5,471,116 A describes a general assembly for controlling the light intensity of a gas discharge lamp. For this purpose, a high voltage is initiated, by means of which the gas discharge lamp is dimmed.

Der Erfindung liegt die Aufgabe zugrunde, eine Schaltungsanordnung zu schaffen, wodurch eine effiziente Helligkeitssteuerung von Gasentladungslampen möglich wird. The invention has for its object to provide a circuit arrangement, whereby an efficient brightness control of gas discharge lamps is possible.

Die Aufgabe wird mittels der Schaltungsanordnung gemäß Anspruch 1 gelöst. The object is achieved by means of the circuit arrangement according to claim 1.

Durch die Schaltungsanordnung (1), wird die Möglichkeit eröffnet, mit geringstem Stromrichter- und Ansteueraufwand eine der Wechselrichterleistung angepasste Anzahl parallel geschalteter Gasentladungslampen zu Dimmen, um eine energieoptimale und den örtlichen Gegebenheiten angepasste Helligkeitssteuerung zu realisieren. Dies wird dadurch erreicht, das der Wechselrichter eine frequenzvariable und betragsmäßig konstant geregelte Trapezspannung bereitstellt, um die Gasentladungslampen, welche weiterhin mit Vorschaltdrossel aber ohne Parallelkondensator beschaltet sind, mit Strom zu versorgen. Weiterhin können Netzschwankungen ausgeregelt werden, was die Betriebszuverlässigkeit der Beleuchtungsanlage erhöht, sowie Fehlerzustände (z. B. Lampendefekt, Erdschluss) über Ferndiagnose weitergeleitet werden. By the circuit arrangement ( 1 ), the possibility is opened, with the least amount of power converter and control effort to dimming an inverter power adapted number parallel-connected gas discharge lamps to realize an energy-optimized and the local conditions adapted brightness control. This is achieved in that the inverter provides a frequency-variable and magnitude constant regulated trapezoidal voltage to power the gas discharge lamps, which are still connected to the choke but without parallel capacitor, with electricity. Furthermore, system fluctuations can be compensated, which increases the operating reliability of the lighting system, and fault conditions (eg lamp defect, ground fault) are forwarded via remote diagnosis.

Die Schaltungsanordnung zur energieoptimalen Helligkeitssteuerung von Gasentladungslampen besteht aus einer Blindleistungskompensationsschaltung und einem Gleichrichter, welche entsprechend des angeschlossenen Netzes ein- oder mehrphasig ausgelegt sind, einem Gleichspannungszwischenkreis, einem Wechselrichter, welcher in Brücken- oder Mittelpunktschaltung ausgeführt ist, einer der Wechselrichterleistung angepassten Anzahl von Gasentladungslampen mit Vorschaltdrossel aber ohne Parallelkondensator, sowie einer übergeordneten Ansteuerung. Die Blindleistungskompensationsschaltung kompensiert zentral am Stromrichtereingang die induktive Blindleistung der Last (Vorschaltdrossel und Gasentladungslampe) aktiv und/oder passiv. Der Gleichrichter und der Gleichspannungszwischenkreis versorgt den Eingang des Wechselrichters mit Energie und dieser stellt eine frequenzvariable und betragsmäßig konstant geregelte Trapezspannung der Last (Vorschaltdrossel und Gasentladungslampe) bereit (siehe 1). The circuit arrangement for energy-optimal brightness control of gas discharge lamps consists of a reactive power compensation circuit and a rectifier, which are designed according to the connected network one or more phases, a DC voltage intermediate circuit, an inverter, which is designed in bridge or mid-point, adapted to the inverter power number of gas discharge lamps Ballast choke but without parallel capacitor, and a higher-level control. The reactive power compensation circuit compensates centrally and centrally at the power converter input the inductive reactive power of the load (ballast choke and gas discharge lamp) actively and / or passively. The rectifier and the DC link supply the input of the inverter with energy and this provides a variable-frequency and magnitude constant regulated trapezoidal voltage of the load (series reactor and gas discharge lamp) (see 1 ).

Ein Verfahren zur Ansteuerung der Schaltungsanordnung moduliert unter Verwendung der Messgrößen der Wechselrichter entspechend der übergeordneten Steuerungsvorgaben die frequenzvariable und betragsmäßig konstant geregelte Trapezspannung (siehe 2). A method for driving the circuit modulated using the measured variables of the inverter in accordance with the higher-level control specifications, the frequency-variable and magnitude constant regulated trapezoidal voltage (see 2 ).

Bevorzugt wird bei vollem Helligkeitsbedarf der Stromrichter (Gleichrichter, Gleichspannungszwischenkreis, Wechselrichter) elektrisch überbrückt und nur im Dimmbetrieb zugeschaltet. Preferably, with full brightness requirement of the converter (rectifier, DC intermediate circuit, inverter) is electrically bridged and switched on only in dimming mode.
