A stage light system for synchronized operation of a show includes a plurality of stage lights, each stage light has an ad hoc network module; and a controller for controlling the stage light. A LAN is established among at least a portion of the stage lights by the controller through the ad hoc network module, in such LAN one of the stage lights is selected as a master node and the rest are taken as a plurality of follower nodes. All of the stage lights in the LAN are configured to perform time synchronization, and send the current show frame information of the master node to the follower nodes and adjust respective show frames of the follower nodes according to the current show frame information of the master node.

A Mesh network-based synchronization system includes a plurality of stage lights and a controller for controlling the stage lights, each of the stage lights having an ad hoc network module. A LAN is established based on the Mesh technology among several stage lights by the controller under the help of the ad hoc network module, one stage light in the LAN acts as a master node, the remaining stage lights forms at least one tree-shaped network topological structure connected to the master node, and some stage lights are selected to form a group. Subsequent to time synchronization of the stage lights in the group, delay time of each stage light relative to the master node is respectively calculated according to the layer level, the master node sends a start command in advance of the corresponding delay time to the respective stage light to synchronously display a show.

Mesh network-based synchronization system of stage light group

A light fixture with redundancy protection includes a light head with a light source inside, a driving mechanism for driving the light head to change the projection direction, an angle detector for detecting the projection direction of the light head, and an original micro-control unit and a redundancy micro-control unit both being coupled to a controller. The original micro-control unit serves to receive an angle control signal from the controller and forward same to the driving mechanism, the redundancy micro-control unit serves to receive the angle control signal from the original micro-control unit or the controller, and both the original micro-control unit and the redundancy micro-control unit are coupled to the angle detector. A safety protection unit coupled to the controller is further included which is for conducting safety protection actions according to a feedback signal from the original micro-control unit or from the redundancy micro-control unit.
