A method for controlling a synchronous, distributed emission of light. A luminous bracelet which is distributed to the audience of a concert is known from the prior art. The problem to be solved is increased integration of the visitors into an audio-visual performance without having to distribute a large number of special devices. The problem is solved by emitting synchronous, distributed light from a plurality of portable personal devices, especially smart devices, wherein setting up of each portable personal device is initiated by the respective portable personal device contacting a control system, particularly a radio network, and the synchronous, distributed emission of light by the plurality of portable personal devices is caused by transferring at least one first piece of information regarding timing and/or at least one second piece of information for color control of the emission of light is effected by the control system.
