1. A vehicle interior lighting system comprising:
a light engine configured to provide light within an interior of a vehicle, the light engine comprising:
a support structure having an outer surface;
independently addressable light emitting diode (LED) segments disposed on the outer surface of the support structure to illuminate different areas of the interior of the vehicle, each of the independently addressable LED segments comprising at least one LED;
a processor configured to receive information from at least one system within the vehicle and generate a control signal based on the information, the information comprising at least one vehicle characteristic selected from a set of vehicle characteristics including occupancy information within the vehicle, vehicular control information, and environmental information external to the vehicle; and
a controller configured to provide, based on the control signal, at least one light control signal to modify at least one emission characteristic of the at least one LED of at least one of the independently addressable LED segments, the controller configured to provide a spot of reduced horizontal illumination surrounding or on a moving object within the vehicle to follow the moving object.
