Einrichtung zur Steuerung und zum Betrieb von
Leuchtdioden zu Beleuchtungszwecken Device for controlling and operating
Light-emitting diodes for lighting purposes

Die Erfindung betrifft eine Beleuchtungseinrichtung gemäß des Oberbegriffs des Anspruchs 1.The invention relates to a lighting device according to the preamble of claim 1.

Leuchtdioden (LEDs) werden wegen ihrer inzwischen sehr hohen Lichtleistung neben Signalanwendungen auch zu Beleuchtungszwecken eingesetzt. Siehe hierzu den Katalog der Firma Insta 1998/99, Seiten 42-49. Daneben sind Lichterketten mit kleinen Glühlampen Stand der Technik, mit denen auch Lauflichtanwendungen realisiert werden.Because of their now very high light output, light-emitting diodes (LEDs) are used not only for signaling applications but also for lighting purposes. See the Insta 1998/99 catalog, pages 42-49. In addition, light chains with small light bulbs are state of the art and can also be used for running light applications.

Nachteil beim Stand der Technik ist die Einstellbarkeit von Betriebsarten wie z.B. verschiedene Dimmeinstellungen, Lauflichteffekte oder auf- und abschwellende Lichteffekte. Hierzu müssen beim Stand der Technik Tasten und/oder Regler am Steuergerät betätigt werden oder die Betriebsart mit einer Fernbedienung eingestellt werden.The disadvantage of the current technology is the ability to set operating modes such as various dimming settings, running light effects or rising and falling light effects. With the current technology, buttons and/or controls on the control unit must be pressed for this or the operating mode must be set using a remote control.

Aufgabe der Erfindung ist es, den Stand der Technik dahingehend zu verbessern, daß die Einstellung der Betriebsart von Beleuchtungseinrichtungen mit Leuchtdioden mittels eines Installationsschalters auf dem Potential des Versorgungsnetzes erreicht wird.The object of the invention is to improve the state of the art in such a way that the setting of the operating mode of lighting devices with light-emitting diodes is achieved by means of an installation switch at the potential of the supply network.

Gelöst wird diese Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale. Weitere Ausgestaltungsmerkmale ist Gegenstand der Unteransprüche.This problem is solved by the features specified in the characterizing part of claim 1. Further design features are the subject of the subclaims.

Durch die Netzunterbrechungen lassen sich verschiedene Betriebsarten einstellen. Hierbei ist jedoch zu beachten, daß gültige Vorschriften nicht verletzt werden. Die Auswertung der Netzunterbrechung erfolgt mittels einer programmierten Logik. Dabei muß sichergestellt werden, daß während der Dauer der Netzunterbrechung die Versorgungsspannung der programmierbaren Logik erhalten bleibt. Mit jeder Netzunterbrechung kann dann in eine weitere Betriebsart umgeschaltet werden, die im Speicher hinterlegt ist und mit dem zugehörigen Programmteil ausgeführt wird. Die Anzeige der Betriebsart muß nicht gesondert erfolgen, da sie durch die Beleuchtungs-Leuchtdioden hinreichend gekennzeichnet ist. Die gültige Normlage besagt, daß Netzunterbrechungen in einem Zeitfenster untergebracht sein müssen, und daß außerhalb dieser Zeit keine Zustandsänderung passieren darf. Die maximale Zeit wird der Einfachheit halber z.B. durch die Pufferung der Versorgungsspannung für die programmierbare Logik bestimmt. Sinnvoll ist hier ein Zeitfenster für die erfindungsgemäß nutzbaren Netzunterbrechungen von 200 ms bis 2 s. Wird die Netzunterbrechung für eine erheblich längere Zeit als die Maximalzeit durchgeführt, fällt die Einrichtung wieder in die erste Betriebsart zurück. Z. B. ist dies die Betriebsart „volle Helligkeit für alle angeschlossenen Leuchtdioden". Wenn mittels Netzunterbrechung die letzte realisierte Betriebsart erreicht wurde, kann mit einer weiteren Netzunterbrechung vorzugsweise wieder der Grundzustand erreicht werden, um letztlich somit ein zyklisches Durchlaufen der Betriebszustände zu erreichen.Different operating modes can be set by interrupting the power supply. However, it must be ensured that valid regulations are not violated. The evaluation of the power supply interruption is carried out using a programmed logic. It must be ensured that the supply voltage of the programmable logic is maintained for the duration of the power supply interruption. With each power supply interruption, a further operating mode can then be switched to, which is stored in the memory and is executed with the associated program section. The operating mode does not have to be displayed separately, as it is sufficiently indicated by the LEDs. The current standard states that power supply interruptions must be accommodated within a time window and that no change in status may occur outside of this time. For the sake of simplicity, the maximum time is determined, for example, by buffering the supply voltage for the programmable logic. A time window of 200 ms to 2 s for the power interruptions that can be used according to the invention is sensible here. If the power interruption is carried out for a significantly longer time than the maximum time, the device falls back into the first operating mode. For example, this is the operating mode "full brightness for all connected LEDs". If the last operating mode implemented was reached by means of a power interruption, the basic state can preferably be reached again with another power interruption in order to ultimately achieve a cyclical run through of the operating states.

Zum Betrieb von Leuchtdioden mit Netzpotential muß ein Vorschaltgerät benutzt werden, um den Strom durch die Dioden zu begrenzen. Dies kann ein herkömmliches Netzteil mitTo operate LEDs with mains potential, a ballast must be used to limit the current through the diodes. This can be a conventional power supply with

gewickeltem Trafo, Gleichrichtung und Siebung oder ein Schaltnetzteil beinhalten. Die Dioden können hierbei mit Schutzkleinspannung SELV betrieben werden, was zu sehr einfachen Bedingungen für die Verlegung der Leuchtdioden führt. Denkbar sind aber auch der Betrieb der Leuchtdioden auf Netzpotential, z.B. mit Kondensator- oder Widerstandsnetzteilen und den damit notwendigen höheren Ansprüchen an den Schutz gegen Berührung.wound transformer, rectification and filtering or a switching power supply. The diodes can be operated with SELV, which leads to very simple conditions for installing the LEDs. However, it is also conceivable to operate the LEDs at mains potential, e.g. with capacitor or resistor power supplies and the higher demands this requires on protection against contact.

Da Leuchtdioden im Gegensatz zu Glühlampen, Halogenlampen oder Energiesparlampen keine hohen Einschaltströme aufnehmen, ist die Stromaufhahme nach Netzunterbrechung im Bereich der Nennstromaufhahme im Dauerbetrieb. Im Gegensatz zu den aufgeführten Leuchtmitteln setzen Leuchtdioden den Stromfluß trägheitslos in Licht um.Since LEDs, unlike incandescent lamps, halogen lamps or energy-saving lamps, do not absorb high inrush currents, the current consumption after a power failure is in the range of the nominal current consumption in continuous operation. In contrast to the lamps listed, LEDs convert the current flow into light without inertia.

Die Last bei der beschriebenen Einrichtung ist so gering, daß sie einfach mit elektronischen Schaltern wie z.B. bipolaren Transistoren oder MOS-Fets geschaltet werden kann.The load in the described device is so small that it can be easily switched using electronic switches such as bipolar transistors or MOS-FETs.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnungsfigur erläutert, die das Steuergerät in einem Blockschaltbild zeigt. Durch Unterbrechung und Wiedereinschaltung mittels des Installationsschalters 1 wird die Netzleitung L/N von der Beleuchtungseinrichtung 4 kurzzeitig unterbrochen. Dieser Vorgang wird durch eine programmierbare Logik 3 in der Beleuchtungseinrichtung 4 erkannt. Je nach Häufigkeit der Unterbrechung werden in der programmierbaren Logik 3 verschiedene Programmteile abgearbeitet. In der programmierbaren Logik 3 ist ein Zeitfenster programmiert, das eine Netzunterbrechung größer 200 ms zuläßt und sicher von kürzeren Netzunterbrechungen unterscheidet, um gültige Normen für Installationsgeräte nicht zu verletzen. Nach Wiederkehr der Netzspannung wird die zugehörige Betriebsart als optische Kontrolle sofort ausgeführt. In der Darstellung sind beispielhaft zwei Ketten von in Reihe geschalteten Leuchtdioden 2 gezeigt.An embodiment of the invention is explained using the drawing, which shows the control device in a block diagram. By interrupting and reconnecting using the installation switch 1, the mains line L/N is briefly interrupted by the lighting device 4. This process is recognized by a programmable logic 3 in the lighting device 4. Depending on the frequency of the interruption, different program parts are processed in the programmable logic 3. A time window is programmed in the programmable logic 3 that allows a mains interruption of more than 200 ms and reliably distinguishes it from shorter mains interruptions in order not to violate valid standards for installation devices. After the mains voltage returns, the corresponding operating mode is immediately carried out as an optical check. The illustration shows two chains of LEDs 2 connected in series as an example.
