1. A lighting-effect coordinated playback method, comprising:
obtaining a target lighting-effect to be played by multiple light strips, and determining a lighting-effect coordination mode and a sub-frame duration of the target lighting-effect, wherein the target lighting-effect includes at least one sub-frame lighting-effect, and the sub-frame duration is used to define a theoretical playback duration of a frame slice of a sub-frame lighting-effect, so as to serve as a reference for determining a refresh time slot of each light strip;
determining each light strip group to which each light strip in the current ambient lamp belongs according to the lighting-effect coordination mode, and determining the refresh time slot of each light strip relative to the sub-frame duration according to a total number of lighting units of the light strip contained in each light strip group; and
according to the corresponding refresh time slot of each light strip, sending frame-slice control data of each frame slice of the light strip corresponding to the sub-frame lighting-effect to the corresponding light strip at intervals, so as to control light units of each corresponding light strip to coordinately complete playback of the sub-frame lighting-effect,
wherein the determining each light strip group to which each light strip in the current ambient lamp belongs according to the lighting-effect coordination mode, and determining the refresh time slot of each light strip relative to the sub-frame duration according to a total number of lighting units of the light strip contained in each light strip group further includes:
identifying the lighting-effect coordination mode in the target lighting-effect, the lighting-effect coordination mode being one of a synchronous playback mode and a sequential playback mode,
when the lighting-effect coordination mode is the synchronous playback mode, respectively regarding the light strips of the current ambient lamp as independent light strip groups, and determining the refresh time slots of each light strip corresponding to the sub-frame duration according to the total number of light units of the light strips of each light strip group;
when the lighting-effect coordination mode is the sequential playback mode, orderly combining the light strips of the current ambient lamp as a single light strip group, and determining the refresh time slots of all the light strips as a whole corresponding to the sub-frame duration according to the total number of light units of all the light strips in the light strip group.
