Abstract
A controller for controlling a generator arranged to the generate a frequency signal for controlling a converter in a driver for driving a light circuit, the controller receiving feed-back information from the light circuit, and a processor; the processor configured to produce, in response to the feed-back information from the light circuit, a control signal arranged to control the generator, the feed-back information comprising a value of a feed-back signal that flows through at least a part of the light circuit or that defines a light intensity of at least a part of the light circuit, and the control signal defining a frequency of the frequency signal, adapt, in response to data information, the control signal, wherein the data information comprises a code for coding light produced by the light circuit; determine a static transfer of a combination of the converter and the light circuit defined by values of the feed-back signal and corresponding values of the frequency of the frequency signal; divide the values of the feed-back signal into intervals of a substantially equal size; and adapt the control signal in interval steps.
