1. A dimming control method for a dimming control device, comprising:
receiving, by a main control chip, a dimming instruction, and determining a plurality of serial signals each corresponding to one of a plurality of output ports in a serial peripheral interface according to the dimming instruction, wherein a serial signal includes a plurality of dimming signals arranged in a sequence;
outputting each serial signal through a corresponding output port according to a different time slot, so as to send the plurality of serial signals to multiple control chips connected in series in the light strip link electrically connected to the corresponding output port; and
causing each control chip in the multiple control chips to respond to the dimming signal corresponding to a time slot of the control chip in the serial signal received by the control chip, and to control a light-emitting element electrically connected to the control chip to change a light-emitting state, wherein the determining the plurality of serial signals each corresponding to one of the plurality of output ports in the serial peripheral interface according to the dimming instruction further comprises: according to a signal format of the control chips, determining a pulse sequence corresponding to each numerical value in a binarization space; extracting out light-emitting state information from the dimming instruction; converting the lighting state information into the dimming signals according to the pulse sequence; according to a serial connection sequence of the multiple control chips connected in series in the light strip link, arranging the corresponding multiple dimming signals to form a serial signal corresponding to the light strip link.
