1. An interior lighting system comprising:
an arrangement of lighting panels mounted at least on opposite lateral sides of a window and adjacent to the window for providing lighting visible as luminance at a wall surface around the outside of the window;
a light sensor arrangement for sensing an exterior lighting level outside or through the window; and
a controller for controlling the lighting delivered by the arrangement of lighting panels in dependence on the sensed exterior lighting level;
wherein each lighting panel includes a reflector for reflecting part of the exterior light which passes through the window to (i) the wall surface, (ii) a backlight, and (iii) a diffusive cover, each lighting panel has a first portion configured to overlap an edge of the window to thereby receive part of the exterior light that passes through the window and a second portion configured to overlap a wall around the edge of the window, and each lightning panel comprises a light source for directing light to the reflector.
