Patent ID: 8120600

Claim:
A light emission control system comprising: 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 plurality of light emitting modules and controlling a corresponding light emitting module; and central controller controlling the plurality of light emitting modules, wherein 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 plurality of 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, wherein a module ID (identification number) is assigned to the light emitting module controller in each of the plurality of light emitting modules, and the plurality of light emitting module controllers are grouped so that the plurality of light emitting module controllers included in each group have module IDs different from each other.
