Abstract
This invention relates to a method and system for controlling light distribution in a space including multiple installed light sources and an external light source. The luminance level of light from said light sources is measured at different measuring areas within the space. A weighed luminance level is determined for each of the measuring areas based on the measured luminance levels, where the weighted luminance level indicates the contribution from the light sources to the measured luminance level at the different measuring areas. This weighed luminance level is used as a tuning parameter for tuning the emitted light at the installed light sources such that the weighed luminance level at each of the different measuring areas substantially matches a pre-defined target luminance level at the different measuring areas.
