Abstract
In one aspect, the invention provides a module for operating at least one lighting means, preferably at least one LED, said module having at least one electrically insulating barrier that separates a primary side, which can be supplied from a mains voltage, from a secondary side of the module, from which secondary side preferably the at least one LED can be supplied. On the secondary side are arranged a control circuit and a passive circuit which is connected to a single input of the control circuit and has at least two resistors, at least one of which is connected in series to a capacitor, the input being selectively connectable via a switch of the control circuit, and the control circuit being designed to detect at least two measurement signals at the input after switching of the switch depending on the degree of loading of the capacitor.
