The present invention provides a light emission control system including a plurality of light emitting modules each including a plurality of light emitting elements and each being a unit to be controlled, light emitting module controllers each provided for each of the light emitting modules and controlling a corresponding light emitting module, and central controller controlling the light emitting modules. The plurality of light emitting module controllers are divided into a plurality of groups, a plurality of light emitting module controllers belonging to each of the groups are connected in a cascade manner within the group, the plurality of groups are connected in parallel with the central controller, and control information transmitted from the central controller to each of the plurality of groups is sequentially transferred from a light emitting module controller to a following light emitting module controller in each of the groups.
