Abstract
The invention relates to a method for controlling a lighting system, wherein the lighting system comprises a plurality of light-emitting ceiling tiles and a control unit for controlling the plurality of light-emitting tiles. The method comprises the step of controlling the plurality of light-emitting tiles to provide a predetermined luminance contrast in the ceiling. The method further comprises the step of, for the predetermined luminance contrast, controlling the plurality of light-emitting tiles to provide a substantially uniform light distribution incident on a target surface such as a horizontal work plane. The method enables the lighting conditions in a room to be adjusted for improving visual comfort and illumination without affecting the illumination at a task level.
