Abstract (en)
[origin: WO2015014713A1] The invention relates to a circuit for the energy supplying of a sequential circuit of typically non-linear loads by means of a current source (1). The load according to the invention is preferably a series circuit of LEDs (4, 10). Said current-operated load, preferably a LED series circuit (4, 10), consisting of one to N elements is partially short-circuited (3, 9) and thus dimmed.
Abstract (de)
Die Erfindung betrifft eine Schaltung (7) zur Energieversorgung einer sequentiellen Schaltung typischerweise nichtlinearer Lasten (4, 10) mit Hilfe einer Stromquelle (1). Vorzugsweise handelt es sich bei der Last um eine Serienschaltung aus LEDs (4, 10). Diese strombetriebene Last, vorzugsweise eine LED-Serienschaltung (4, 10), bestehend aus ein bis N Elementen und wird partiell kurzgeschlossen und damit gedimmt.
