Abstract (en)

An apparatus for generating a drive signal for a lamp device comprises a pulse generator for generating a first pulse train in response to a first brightness request for a first brightness and for generating a second pulse train in response to a second brightness request for a second brightness. The first pulse train has a first frequency and the second pulse train has a different second frequency. The second pulse train comprises two neighboring pulses of the first pulse train and comprises a further pulse between the two neighboring pulses, the further pulse not being comprised in the first pulse train.
