Drive device and method for operating at least one series circuit of light-emitting diodes

摘要

A device for at least one series circuit of multiple light-emitting diodes, having a voltage regulation unit for regulating an operating voltage for the at least one series circuit of the light-emitting diodes. A current regulation unit for regulating the current through the particular series circuit of light-emitting diodes is provided for each series circuit of light-emitting diodes, and the current regulation unit is connected to the voltage regulation unit in order to transmit a current regulation signal to the voltage regulation unit.
