Abstract: Lighting device suitable for multiple voltage sources, comprising a first circuit (1) with diode circuits coupled to input terminals (2, 3) for receiving first voltage signals from first circuits (21) such as voltage-to-voltage converters. The diode circuits comprise diodes (11-14) for rectifying the first voltage signals and are coupled to output terminals (4, 5) for supplying second voltage signals. First capacitors (15) are coupled to the output terminals (4, 5) for buffering the second voltage signals and for offering buffered second voltage signals to second circuits (22) such as voltage-to-current-converts for feeding light circuits (30) comprising one or more light emitting diodes. Second capacitors (16, 17) coupled in parallel to one of the diodes (11-14) provide a charge-pump effect to improve performances of the first and second circuits (21, 22) and the light circuits (30).

Abstract: Circuits (1) for receiving output signals from transformers (2) comprise filters (11) and switches (12). In the case of magnetic/electronic transformers, the filters (11) are activated/deactivated, for example for filtering/not filtering unwanted signals coming from converters (4). The filters (11) may comprise capacitors. The switches (12) may comprise fuses. Output signals of magnetic/electronic transformers comprise relatively low/high frequency signals that result in relatively small/large currents flowing through the capacitors, which currents will not blow/blow the fuses. The capacitors, when activated, form, together with leakage inductances of the magnetic transformers, electromagnetic interference filters. Alternatively, the circuits (1) may further comprise detectors (13) for detecting transformer types and for controlling the switches (12) in response to detection results. Then, possibly, the detectors (13) are arranged to detect frequency signals in the output signals and comprise comparators (15) for comparing detection results (14) with threshold values.
