Abstract
A lighting system uses an array of lighting elements which provide light in different directions. The intensity of the lighting elements is controlled in dependence on a time-varying parameter related to at least one of a position of a light emitting or light reflecting body, and an intensity, color or color temperature of the light emitted or reflected by the body, such that the system can simulate directional sunlight.
