Individual light sources i.e. LEDs, controlling device for lighting device in motor vehicle i.e. aircraft, has current regulation unit that is assigned to parallel circuits, where individual light sources are arranged in parallel circuits

摘要

The device (1) has a common power supply unit (10) with a voltage regulation unit and a control and/or regulation unit (9) for individual light sources (L1-Ln), where the individual light sources are arranged in parallel circuits (3.1-3.n) and a current regulation unit (8) is assigned to the parallel circuits. The current regulation unit has current-sources and/or current sinks (S1-Sn) which are assigned to decrease the parallel circuits. The current-sources and/or the current sinks are summarized in a current source module and/or a current-sink module (11).
