A lighting system comprising at least two individually controllable light sources (102, 104) and a control unit, wherein the control unit is connectable to the at least two individually controllable light sources (102, 104) and configured to control the at least two individually controllable light sources (102, 104), wherein the control unit is further configured to: - control a first lighting system configuration comprising the at least two individually controllable light sources (102, 104) each configured to emit an illumination pattern (114, 116), respectively, together forming a joint first illumination pattern of the first lighting system configuration, the joint first illumination pattern illuminating a predefined illumination area; - detect and store an initial set of illumination parameters being indicative of the first illumination pattern; - detect, using sensors comprised with and/or connected to the control unit, a subsequent set of illumination parameters being indicative of a second illumination pattern formed jointly by individually controllable light sources (102, 106) of a second lighting system configuration, the second lighting system configuration being different from and being a sub-set of the first lighting system configuration; - compare the initial set with the subsequent set of illumination parameters to determine if any difference exists; and - control, if any difference exists, in dependence on the initial set and the subsequent set of illumination parameters, the light sources (102, 106) of the second lighting system configuration so as to jointly form a third illumination pattern, the third illumination pattern being an approximation of the first illumination pattern, the joint third illumination pattern illuminating the same predefined illumination area as previously illuminated by the joint first illumination pattern, thereby minimizing a difference between the first illumination pattern and the third illumination pattern. - control a first lighting system configuration comprising the at least two individually controllable light sources (102, 104) each configured to emit an illumination pattern (114, 116), respectively, together forming a joint first illumination pattern of the first lighting system configuration, the joint first illumination pattern illuminating a predefined illumination area; - detect and store an initial set of illumination parameters being indicative of the first illumination pattern; - detect, using sensors comprised with and/or connected to the control unit, a subsequent set of illumination parameters being indicative of a second illumination pattern formed jointly by individually controllable light sources (102, 106) of a second lighting system configuration, the second lighting system configuration being different from and being a sub-set of the first lighting system configuration; - compare the initial set with the subsequent set of illumination parameters to determine if any difference exists; and - control, if any difference exists, in dependence on the initial set and the subsequent set of illumination parameters, the light sources (102, 106) of the second lighting system configuration so as to jointly form a third illumination pattern, the third illumination pattern being an approximation of the first illumination pattern, the joint third illumination pattern illuminating the same predefined illumination area as previously illuminated by the joint first illumination pattern, thereby minimizing a difference between the first illumination pattern and the third illumination pattern.
