Abstract
The invention provides a method and system of controlling illumination characteristics of a plurality of lighting segments. According to the invention, there is provided an illumination system, comprising: a plurality of lighting segments; a detecting subsystem configured to detect an illumination intensity and/or color of lights emitted from each lighting segment; a controller configured to receive the detecting subsystem's output signals representing illumination intensity and/or color of lights emitted from each lighting segment and to generate sets of driving signals to respectively adjust the driving currents of each lighting segment in response to the output signals, so as to adjust the illumination intensity and/or color of the lights emitted from each lighting segment in accordance with a predetermined illumination setting, wherein each set of driving signals has a unique period feature which is distinguished from that of other sets of driving signals corresponding to other lighting segments.
