A method has been proposed to operate a lighting control system (100) consisting of photo sensors (110), dimmable electric light sources (120), a motorized shading system(130) and a controller (140). Initial illuminance data based on different environmental conditions such as exterior illuminance, blind height, and blind angle are received and classified. Estimators are calculated for these different environmental conditions. The illuminance in the taskplane is estimated. Based upon the estimated taskplane illuminance, the dimmable electric light sources (120) and the motorized shading system (130) are adjusted to meet a required setpoint. |
