The present invention relates to an illumination system (1) for illuminating an object (2) located in an object space (8), comprising an illumination unit (3) adapted to emit illumination light (4b) into the object space (8), a distance measuring unit (5) for taking a distance image (41) of the object space (8) with the object (2) located therein, which distance measuring unit is arranged in relation to at least a part of the illumination unit (3) so that it is fixed at this part of the illumination unit, a marker system (6) with a marker emitter unit (66a) for emitting a marker signal (7), and a marker receiver unit (6ab) for detecting at least a portion (7a) of the marker signal (7), wherein the illumination system (1) is configured to localize the object (2) on the basis of the distance image (41) within an area of the object space (8) and individualise the object using the signal portion received with the marker receiver unit (6ab) and to illuminate the object (2) accordingly with the illumination unit (3).
