  • the adjustable reference value is from a central control unit of the digital control circuit specified.
  • the reference value can also be stored in a memory via a D / A converter, the contents of the memory being fed to a comparator, to whose other input the analog measuring signal is applied. Again, the output of the comparator is a signal that can be further processed digitally.
  • the reference value may depend on the current operating state of the operating device and / or the current phase position of the at least one measuring signal.

Abstract

L'invention concerne l'utilisation d'un dispositif d'utilisation d'un élément d'éclairage, notamment d'un ballast électronique de lampes à décharge gazeuse. L'élément d'éclairage est commandé par un circuit de commande numérique (1) par émission de signaux de commande. Au moins un signal de mesure analogique est ramené au circuit de commande numérique (1), comparé à une valeur de référence réglable dans le circuit de commande numérique (1), et la valeur de référence réglable est émise par une unité de commande centrale (2) du circuit de commande numérique (1). La valeur de référence dépend de l'état d'utilisation du dispositif d'utilisation et/ou de la position de phase actuelle du ou des signaux de mesure.
