Abstract
The invention provides a lighting system for providing illumination on a surface (16), comprising a first array (10) of light sources (13) and a first reflector (12) for forming a first pattern on the surface, and a second array (10) of light sources (13) and a second reflector (12) for forming a second pattern on the surface (16), arranged concentrically around the first pattern. A controller (44) controls the first and second arrays (10) of light sources (13) to apply a cyclic function thereby to define one or more radially propagating rings or partial rings of illumination on the surface (16). This is enables a dynamic ripple lighting effect to be provided on the surface (16).
