摘要

The circuit arrangement is provided with a supply connection (V-cc) for coupling with a supply voltage, and an output having two output ports for coupling with the light emitting diodes (LED-1,LED-2,LED-3). A controlled resistance (T1) is provided with a control electrode, a reference electrode and a working electrode.
