Abstract

An optical driver arrangement (10) comprises a comparator (11) and a pulse generator (15). The comparator (11) comprises a first input (12) for receiving a sensed output signal (S1) derived from a sensor signal (S2) generated by a light sensor (24), a second input (13) for receiving a reference signal (S3) and a comparator output (14) for providing a comparator signal (S4). The pulse generator (15) comprises a control input (16) coupled to the comparator output (14) and a generator output (22) for providing a driver signal (S5) to a light source (21). The driver signal (S4) comprises a series of at least one pulse and a parameter of the driver signal (S4) is controlled by the comparator signal (S4).
