Abstract
The present document relates to solid state lighting (SSL) devices. A driver circuit for phase-cut dimmable SSL based lighting assemblies is described. A control circuit for a power converter is provided. The power converter is configured to convert an input power derived from a mains power supply into a drive power for a light source. The control circuit comprises a dimmer mode detection unit to determine a first dimmer mode. The first dimmer mode indicates if the input power has been derived from the mains power supply using a dimmer. The control circuit comprises a state processor configured to determine a first operation mode of the power converter. The pre-determined first state information is dependent on the first dimmer mode. The control circuit comprises a first control unit configured to generate a first control signal for operating the power converter in accordance to the first operation mode.
