Abstract

  • 2.1. Die Erfindung betrifft ein Verfahren zur Leuchtmittelüberwachung von Lichtrufsystemen für den Pflegebereich mit folgenden Schritten: In einer Initialisierungsphase, Erfassen eines durch ein Leuchtmittel fließenden Stroms oder einer hierzu korrelierten Größe, Bestimmen und Abspeichern eines Referenzwerts anhand des erfassten Werts, in einer Betriebsphase, Erfassen des durch das Leuchtmittel fließenden Stroms oder der hierzu korrelierten Größe und Bestimmen eines Vergleichswerts, Vergleichen des in der Initialisierungsphase bestimmten Referenzwerts mit den in der Betriebsphase bestimmten Vergleichswert und Auswerten des Vergleichsergebnisses.
  • 2.2. Verwendung z.B. für Lichtrufsysteme in Krankenhäusern.

  • 2.1. The invention relates to a method for illuminant monitoring of nurse call systems for the care sector with the following steps: In an initialization phase, detecting a current flowing through a light source or a correlated thereto size, determining and storing a reference value based on the detected value, in an operating phase, detecting the by the luminous flux flowing or the magnitude correlated thereto and determining a comparison value, comparing the reference value determined in the initialization phase with the comparison value determined in the operating phase and evaluating the comparison result.
  • 2.2. Use eg for nurse call systems in hospitals.
