Patent ID: 8878457

Claim:
A control unit for a lighting system comprising at least two individually controllable light sources, 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 to emit a first illumination pattern provided jointly by the at least two light sources of the first lighting system configuration; detect and store an initial set of illumination parameters being indicative of the first illumination pattern; determine a subsequent set of illumination parameters being indicative of a second illumination pattern provided by a second lighting system configuration comprising individually controllable light sources, the second lighting system configuration being different from the first lighting system configuration; and control, in dependence on the initial set and the subsequent set of illumination parameters, the second lighting system configuration to emit a third illumination pattern, the third illumination pattern being an approximation of the first illumination pattern.
