Control circuit for light emitting diode array has current supply unit to diode array and current measuring and control units

摘要

A control circuit for a light-emitting diode array (2) comprises at least one diode system (DA1-m) with a current supply unit providing a given current, a device (5) to measure the current through the diodes and a current control unit (6). An independent claim is also included for an operating process for the above.
