13 Claims

1. A system for mimicking daylight in a space by using one or more light sources having a redirectable light output, said system comprising:

at least one input interface;

at least one control interface; and

at least one processor configured to:

determine a daylight-mimicking light output direction for said light output in said space based on a time of day,

obtain input via said at least one input interface,

determine an estimated or detected position of a person or animal in said space from said input,

determine an adjusted light output direction for said one or more light sources in dependence on said daylight-mimicking light output direction and said estimated or detected position, and

control, via said at least one control interface, said one or more light sources to render said light output in said adjusted light output direction.
