Abstract
Description
Die Erfindung betrifft eine Notleuchte, wie beispielsweise ein Hinweiszeichen für einen Rettungsweg.The invention relates to an emergency light, such as a sign for an escape route.
Derartige Notleuchten dienen dazu, zumindest in Notsituationen, wie zum Beispiel einem Feuer in einem Gebäude, einen Rettungsweg aus dem Gebäude anzuzeigen. Hierzu sind Notleuchten mit einer Batterie versehen, um unabhängig von externen Spannungsquellen operieren zu können. Eine derartige Leuchte ist beispielsweise in
Es ist bekannt, derartige Notleuchten mit einer Überwachungsvorrichtung zu versehen, die den Funktionszustand der Batterie und des Leuchtmittels überwacht. Die Funktionsfähigkeit der Batterie und des Leuchtmittels sind für die Notleuchte von grundlegender Bedeutung. Eine den Ladezustand der Batterie überwachende Überwachungsvorrichtung wird beispielsweise in
Der Erfindung liegt die Aufgabe zugrunde, die Sicherheit von Notleuchten zu verbessern.The invention has for its object to improve the safety of emergency lights.
Die erfindungsgemäße Notleuchte ist durch die Merkmale von Anspruch 1 definiert. Demnach ist ein akustischer Signalgeber vorgesehen, der dazu ausgebildet ist, ein akustisches Warnsignal auszugeben, sobald die Überwachungsvorrichtung das Nichtvorliegen eines Funktionszustands der Batterie erkennt. Wird zum Beispiel eine bestimmte Mindestspannung der Batterie unterschritten wird dies von der Überwachungsvorrichtung erkannt. Die Überwachungsvorrichtung veranlasst dann den akustischen Signalgeber, das Warnsignal auszugeben.The emergency light according to the invention is defined by the features of claim 1. Accordingly, an acoustic signal transmitter is provided, which is designed to emit an acoustic warning signal as soon as the monitoring device detects the absence of a functional state of the battery. If, for example, a certain minimum voltage of the battery is exceeded, this is detected by the monitoring device. The monitoring device then causes the acoustic signal transmitter to output the warning signal.
Bei dem Warnsignal handelt es sich vorzugsweise um ein Tonsignal, das für eine vorgegebene Zeitdauer ausgegeben wird und in regelmäßigen Abständen wiederholt wird. Beispielsweise kann es sich bei dem Tonsignal um einen Dauerton mit einer Länger im Bereich zwischen 30 und 90 Sekunden und vorzugsweise von etwa 60 Sekunden handeln. Hierbei kann das Tonsignal in Abständen im Bereich zwischen 30 und 90 Minuten und vorzugsweise von etwa 60 Minuten wiederholt werden. Entscheidend ist, dass das Tonsignal bei jeder Ausgabe von gleicher Länge ist und dass die Abstände zwischen den Tonsignalen immer gleich sind.The warning signal is preferably a sound signal that is output for a predetermined period of time and is repeated at regular intervals. For example, the audio signal may be a continuous tone with a duration in the range between 30 and 90 seconds, and preferably about 60 seconds. Here, the sound signal may be repeated at intervals in the range between 30 and 90 minutes, and preferably about 60 minutes. It is crucial that the sound signal at each Output is of equal length and that the distances between the sound signals are always the same.
Das Warnsignal kann über einen an dem Gehäuse der Notleuchte vorgesehenen Knopf deaktiviert werden. Alternativ oder ergänzend kann das Warnsignal durch Abschalten der Netzspannung deaktiviert werden. Nach anschließender Reaktivierung durch Loslassen des Knopfes oder durch Wiederherstellen der Netzspannung gibt der akustische Signalgeber das Warnsignal nach mehreren Tagen und vorzugsweise nach ungefähr einer Woche oder nach etwa 168 Stunden erneut aus, wenn der von der Überwachungsvorrichtung erkannte Nichtfunktionszustand immer noch vorliegt.The warning signal can be deactivated via a button provided on the housing of the emergency light. Alternatively or additionally, the warning signal can be deactivated by switching off the mains voltage. After subsequent reactivation by releasing the button or by restoring the mains voltage, the audible alarm re-emits the warning signal after several days, and preferably after about one week, or after about 168 hours if the non-functional condition detected by the monitoring device is still present.
Die Batterie kann mit einem Thermistor, zum Beispiel mit einem NTC oder mit einem PTC, versehen sein, um Temperaturschwankungen zu erfassen. Die Überwachungsvorrichtung kann dann auch die Veränderung des temperaturabhängigen Widerstands erkennen.The battery can be provided with a thermistor, for example with an NTC or with a PTC, to detect temperature fluctuations. The monitoring device can then also detect the change in the temperature-dependent resistance.
Im Folgenden wird ein Ausführungsbeispiel der Erfindung näher erläutert.In the following an embodiment of the invention will be explained in more detail.
Die Notleuchte nach dem Ausführungsbeispiel der Erfindung weist ein quaderförmiges Gehäuse mit zwei auf gegenüberliegenden Seiten vorgesehenen Signalträgern auf. Mittig zwischen den Signalträgern enthält das Gehäuse ein Dauerleuchtmittel. In dem Gehäuse ist eine Batterie zur permanenten Stromversorgung des Leuchtmittels vorgesehen.The emergency light according to the exemplary embodiment of the invention has a cuboidal housing with two signal carriers provided on opposite sides. In the middle between the signal carriers, the housing contains a continuous illuminant. In the housing, a battery for permanent power supply of the lamp is provided.
Das Gehäuse weist eine elektrisch mit der Batterie verbundene Überwachungsvorrichtung mit einem Mikroprozessor auf, der zum Erkennen und Überwachen des Ladezustands der Batterie, also zum Überwachen der Batteriespannung, ausgebildet ist. Sobald ein kritischer Schwellenwert der Batteriespannung unterschritten wird aktiviert der Mikroprozessor einen in Form eines Lautsprechers an dem Gehäuse vorgesehenen akustischen Signalgeber.The housing has an electrically connected to the battery monitoring device with a microprocessor, which is designed to detect and monitor the state of charge of the battery, so for monitoring the battery voltage. As soon as a critical threshold value of the battery voltage is exceeded, the microprocessor activates an acoustic signal transmitter provided in the form of a loudspeaker on the housing.
Der Mikroprozessor ist dazu programmiert, über den akustischen Signalgeber einen Dauerton mit einer Länge von 60 Sekunden auszugeben, der in Abständen von 60 Minuten wiederholt wird.The microprocessor is programmed to emit a continuous tone with a duration of 60 seconds via the acoustic signal generator, which is repeated at intervals of 60 minutes.
An dem Gehäuse ist ein Testknopf vorgesehen, mit dem sich das akustische Warnsignal abschalten lässt. Der Mikroprozessor erkennt eine Betätigung des Knopfes und schaltet das Warnsignal ab. Sobald der Knopf losgelassen wird veranlasst der Mikroprozessor den akustischen Signalgeber, nach 168 Stunden das Warnsignal erneut auszugeben, wenn der Schwellenwert der Batteriespannung dann immer noch unterschritten wird.On the housing a test button is provided, with which the acoustic warning signal can be switched off. The microprocessor detects an actuation of the button and turns off the warning signal. Once the button is released, the microprocessor will cause the beeper to re-sound the alarm after 168 hours if the battery voltage threshold is still exceeded.
Hierzu führt die Überwachungsvorrichtung nach 168 Stunden einen erneuten Test durch.For this purpose, the monitoring device performs a new test after 168 hours.
Die Batterie ist mit einem NTC versehen. Der Mikroprozessor überprüft bei einem Austausch der Batterie das Vorhandensein des Thermistors. Zudem erfasst und überwacht die Mikroelektronik den Widerstand des Thermistors und gibt bei Überschreiten eines vorgegebenen Widerstandwertes, der einer kritischen Temperatur entspricht, ein Warnsignal aus.The battery is equipped with an NTC. The microprocessor checks the presence of the thermistor when replacing the battery. In addition, the microelectronics detects and monitors the resistance of the thermistor and outputs a warning signal when a predetermined resistance value, which corresponds to a critical temperature, is exceeded.
Alternativ kann der Thermistor auch ausschließlich dazu vorgesehen sein, eine für die Notleuchte geeignete Batterie zu identifizieren, ohne dass der temperaturabhängige Widerstand von der Überwachungsvorrichtung überwacht wird.Alternatively, the thermistor may also be exclusively intended to identify a battery suitable for the emergency light without the temperature-dependent resistance being monitored by the monitoring device.
