Abstract
An illumination system (1) is based on a window (21) having controllable transmittance and a light guide system (31) arranged for transferring light from a light guide input (33) to a light guide output (34). The light guide output is located in a same space (50) as the window (21), but at a distance therefrom (21). The illumination system includes elements for balancing (40) the transmittance of the window and a throughput of the light guide system. Preferably, the window is an outer window, the light guide input (33) is arranged for gathering day light and the light guide output (34) is arranged to illuminate an area (52) within sight from the window (21). Preferably the transmittance of the window (21) and/or the light throughput of the light guide system (31) are controlled. A method for illuminating a space (50) having a window (21) with controllable transmittance is presented.
