Abstract
A circuit is disclosed for supplying energy to a sequential circuit of typically non-linear loads by a current source. The load is preferably a series circuit of light emitting diodes (LEDs). Said current-operated load, preferably a LED series circuit, consisting of one to N elements is partially short-circuited and thus dimmed.
