Abstract
The present invention proposes a method, apparatus, controller and system for controlling illuminance. Specifically, the system comprises at least one light source, each of the at least one light source comprising a plurality of light modules and each of the plurality of light modules being adjustable independently; and a controller configured to control the illuminance of a target area in the lighting system. One or more light modules associated with the illuminance of the target area are selected from the at least one light source based on the position relationship between the at least one light source and the target area and a lighting distribution of each of the at least one light source. Then, at least one of the selected one or more light modules is adjusted to meet a certain requirement for the illuminance of the area. As a result, personalized lighting for an open area is effectively achieved.
