displaying a plane composition of a target splicing-lamp, the plane composition including form patterns corresponding to multiple lamp blocks of the target splicing-lamp, and each form pattern including multiple light-emitting areas;

loading effect configuration information corresponding to each layer described in a lighting-effect template into a lighting-effect editing area for display, the effect configuration information including area information and lighting-effect information, the area information being used to specify an effective light-emitting area of a lamp block, and the lighting-effect information being used to describe a lighting-effect process acting on the effective light-emitting area;

in response to a layer on-top event, determining and marking the effective light-emitting area in the form pattern of each lamp block in the plane composition according to the area information of a current layer that is set on top, obtaining a plane topological pattern corresponding to the current layer, and applying the lighting-effect information of the current layer to the plane topological pattern to display a preview lighting effect of the current layer; and

responding to a lighting-effect application instruction, encapsulating edited effect configuration information of each layer in a lighting-effect application package, and pushing the lighting-effect application package to the target splicing-lamp for application.
