1. A Mesh network-based synchronization system of a stage light group, comprising
a plurality of stage lights, each of the stage lights having an ad hoc network module; and
a controller for controlling the plurality of stage lights, which is configured to control several stage lights to establish a local area network (LAN) based on Mesh technology under the help of the ad hoc network module, wherein one stage light in the LAN is taken as a master node, at least one tree-shaped network topological structure connected to the master node is formed by the remaining stage lights in the LAN, and some stage lights in the LAN are selected to form a group,
wherein it is configured that subsequent to time synchronization of the stage lights in the group, delay time of each stage light in the group relative to the master node is respectively calculated according to a layer level between the corresponding stage light in the group and the master node, and the master node is configured to send a start command in advance of the corresponding delay time to the respective stage light to synchronously display a show by the stage lights within the group.
