A lighting system comprising at least two individually controllable light sources and a control unit , wherein the control unit is connectable to the at least two individually controllable light sources and configured to control the at least two individually controllable light sources , wherein the control unit is further configured to: - control a first lighting system configuration comprising the at least two individually controllable light sources each configured to emit an illumination pattern , 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 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 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 each configured to emit an illumination pattern , 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 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 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 . <EOS>
