Abstract: A light-emitting data transmission method includes obtaining display layout information of a lamp, and generating a dot matrix drawing interface on a display interface corresponding to the display layout information. The lamp includes a plurality of light-emitting units, and each curtain light is mapped to a coordinate point in the dot matrix drawing interface. The method also includes obtaining bitmap graphic data generated by receiving an external editing instruction from the dot matrix drawing interface, converting the bitmap graphic data into bitmap image data in a predetermined image format, and outputting the bitmap image data to a controller, so that the controller parses the bitmap image data into the light-emitting information corresponding to each light-emitting unit. The light-emitting information is used to control the corresponding light-emitting unit to emit light, such that light emitted by the plurality of light-emitting units are combined to form a predetermined light effect.

Abstract: A lighting control method includes: receiving light-emitting color data, the light-emitting color data including color values corresponding to a plurality of preset light-emitting channels; determining at least one additional light-emitting channel other than the plurality of preset light-emitting channels among the actual light-emitting channels of a lighting device; generating a color value of the additional light-emitting channel according to color values of the plurality of preset light-emitting channels in the light-emitting color data, and using the color values corresponding to the plurality of preset light-emitting channels and the additional light-emitting channel as target light-emitting color data; and transmitting the target light-emitting color data to each lamp bead chip in the lighting device to control corresponding lamp beads to emit light according to the color values corresponding to the actual light-emitting channel to which the lamp beads belong.
