Estimating the term…
The invention relates to a module for operating at least one illuminant, preferably at least one LED, said module having at least one electrically insulating barrier, which separates a primary side that can be supplied, originating from a mains voltage, from a secondary side of the module, from which the at least one illuminant can preferably be supplied. A secondary-side passive circuit is provided, which is connected in a supply path to a primary-side control circuit across the barrier via a galvanically isolated converter. The primary-side control circuit is designed to apply a test signal with predetermined temporal development to the secondary-side passive circuit (via the converter) and simultaneously to monitor a measurement signal generated thereby on the secondary side and fed back into the supply path, more particularly to monitor an increase of current in the converter.
A module for operating at least one illuminant, preferably at least one LED, with at least one electrically insulating barrier, which isolates a primary side capable of being supplied originating from a mains voltage, from a secondary side of the module, from which the at least one illuminant can preferably be supplied,
A method for the passive feedback of a measurement signal from the secondary side of an electrically insulating barrier to a control circuit arranged on the primary side relative to the latter, which is connected across the barrier in a supply path via a galvanically isolated converter to a secondary-side passive circuit,
