Abstract
Description
Die Erfindung betrifft ein Elektronikmodul für den Einsatz in Notleuchten. Notleuchten sind Leuchten, die wirksam werden, wenn die Stromversorgung der Allgemeinbeleuchtung ausfällt, und sie werden vorwiegend zum Beleuchten von Rettungswegen oder Arbeitstätten mit besonderer Gefährdung eingesetzt.The The invention relates to an electronic module for use in emergency lights. Emergency lights are lights that take effect when the power supply to the General lighting fails, and they are mainly used to illuminate escape routes or workplaces with particular risk used.
Typisch für solche Systeme mit Notleuchten ist:
- – das Betreiben einer oder mehrerer elektrischer Lichtquellen, welche beispielsweise als Glühlampen oder, aus Energieersparnisgründen, vorzugsweise als Leuchtstofflampen ausgeführt sein können,
- – die wechselweise Versorgung solcher Lampen über Wechselspannungsnetz 110V oder 230V, (Netzbetrieb) oder über eine eingebaute Stromquelle (Akku) mit Kleinspannung, beispielsweise 3 bis 20 V, (Notbetrieb), je nach Betriebsart,
- – dabei treten typischerweise vier Betriebsarten auf 1. Dauerschaltung: Lampe wird über Wechselspannungsnetz ständig gespeist (Netzbetrieb), 2. Bereitschaftsschaltung: Lampe nur dann eingeschaltet, wenn Stromversorgung ausfällt, 3. Batteriebetrieb (Notbetrieb): Lampe wird von eingebauter Stromquelle gespeist, wenn allgemeine Stromversorgung gestört ist oder ausfällt, 4. Ruhe-Zustand (stand by): Zustand einer Notleuchte, die absichtlich bei ausgeschalteter Stromversorgung kurzzeitig gesperrt wird.
- The operation of one or more electrical light sources, which can be embodied, for example, as incandescent lamps or, for reasons of energy saving, preferably as fluorescent lamps,
- - the alternate supply of such lamps via AC mains 110V or 230V, (mains operation) or via a built-in power source (battery) with low voltage, for example 3 to 20 V, (emergency operation), depending on the operating mode,
- - There are typically four operating modes: 1. Permanent switching: lamp is continuously supplied via AC mains (mains operation), 2. Standby mode: lamp is only switched on when the power supply fails, 3.Battery operation (emergency operation): lamp is supplied by a built-in power source when general Power supply is faulty or fails, 4. Sleep mode (stand by): State of an emergency light that is intentionally blocked for a short time when the power supply is switched off.
Das Elektronikmodul dieser Erfindung ist geeignet für Notleuchten mit einer Leuchtstofflampe im Niedrigleistungsbereich bis etwa 150 Watt, speziell jedoch für Leistungen unterhalb von 10 Watt. Die bekannten Notleuchten in diesem Bereich zeigen eine Reihe von Nachteilen, die mit dieser Erfindung beseitigt werden. Diese Nachteile sind u. a.:
- – das Betreiben der Leuchtstofflampe bei zu geringer Leistung,
- – das Zünden der Leuchtstofflampe ohne Vorheizen (Kaltstart), was zu einer erheblichen Reduzierung der Lebensdauer führt,
- – die hohe Temperaturbelastung der Bauteile,
- – das Nichteinhalten einschlägiger Normen vor allem hinsichtlich der Reduzierung der minimalen Nennbetriebsdauer durch erhöhte Stromaufnahme im Notbetrieb bzw. zu geringer Beleuchtungsstärke
- - operating the fluorescent lamp when the power is too low,
- - igniting the fluorescent lamp without preheating (cold start), which leads to a considerable reduction in the service life,
- - the high temperature load on the components,
- - Failure to comply with relevant standards, especially with regard to the reduction of the minimum nominal operating time due to increased current consumption in emergency operation or insufficient illuminance

Batterie gegen zusätzliche
Stromabgabe zu schützen,
so dass dieser in Form eines Wechselspannungstransformators mit
Netzfrequenz, ein großes
Volumen beansprucht, oder in Form von Kondensatoren ebenfalls volumenbedingt
aufwendig und kostspielig wird, indem gleichzeitig die Batterie
