Abstract
A driver circuit for programmable solid state light bulb assemblies including light emitting diodes is operable to provide a drive current to a light source of the light bulb assembly. The controller comprises a data storage unit storing a test scenario for calibration of the light bulb assembly; wherein the test scenario indicates a sequence of states of the light source; wherein a state of the light source is associated with settings of the driver circuit; a data input unit receiving a command signal via a modulated electricity supply signal; and a data processing unit retrieving the test scenario from the data storage unit; in dependence of the received command signal, generating a control signal for operating the light source in at least one state of the sequence of states of the test scenario; and to output the control signal.
