20160073472 | Module for Lighting Means With Combined Secondary-Side Measurement Signal Detection - 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. | 03-10-2016 |
20160105121 | Module Having Measurement Signal Feedback Via A Galvanically Isolated Converter - 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. | 04-14-2016 |
