CONTROL SIGNAL TRANSMISSION METHOD FOR LAMP SYSTEM

Original (Chinese)

A control signal transmission method for a lamp system includes: acquiring signal states of a red-line original control signal, a green-line original control signal and a blue-line original control signal periodically; outputting, within an output period, a red-line conversion signal, a green-line conversion signal and a blue-line conversion signal sequentially according to the signal states of the original control signals; performing voltage stabilization on the conversion signals to obtain a red-line regulation signal, a green-line regulation signal and a blue-line regulation signal at different levels; outputting a combined control signal consisted of the red-line regulation signal, the green-line regulation signal and the blue-line regulation signal; receiving and detecting the combined control signal to obtain the red-line regulation signal, the green-line regulation signal and the blue-line regulation signal; and outputting the red-line regulation signal, the green-line regulation signal and the blue-line regulation signal to lamps of the lamp system.
