Claim Text:
1. A Circuit arrangement for operating at least one low-power lighting unit with a self-oscillating power supply, the self-oscillating power supply having a primary side for connection to a power source and a secondary side for connection to the circuit arrangement, the circuit arrangement comprising: an input for receiving an operating voltage from said self-oscillating power supply at the secondary side of the self-oscillating power supply, an output for connection to one or more low-power lighting units, a pulse generator, connected with said secondary side of said self self-oscillating power supply and configured to inject at least one trigger pulse into the secondary side of said self-oscillating power supply during operation and a pulse controller, connected at least with said pulse generator and configured to control said pulse generator in dependence of said operating voltage.
