An illumination system (1) comprises a plurality of light source units (10) arranged according to an array, each light source unit comprising at least one controllable light source (12) and a unit controller (11). A communication network (30) has communication lines (32; 33) extending along a straight line between neighboring light source units (1OA, 1OB; 1OB, 10C). A common system controller (20) issues control signals (Sc) for the individual unit controllers (11), taking into account their positions and orientations, to achieve a desired illumination effect. The common system controller is capable of automatically determining the positions and orientations of the light source units (10). To this end, the light source units comprise length detection means (60) for detecting the lengths of the communication lines, and direction detection means (50) for detecting the relative directions of the communication lines, and communicate the measured results to the common system controller.
