The invention relates to an intelligent lamp controller for controlling at least one group of electric light sources. The intelligent lamp controller includes a power source switch unit and a first processing unit; the power source switch unit includes a first input end, a second input end, and an output end; the first processing unit includes a power supply end, a signal input end, and a signal output end; the first input end of the power source switch unit is connected with the live line L end of an external power grid; the second input end of the power source switch unit is connected with the neutral line N end of the external power grid; the output end of the power source switch unit is connected with the power supply end of the first processing unit, and is used for converting alternating current outputted from the external power grid into a preset direct-current voltage and providing the preset direct-current voltage to the first processing unit; the signal input end of the firstprocessing unit receives signals transmitted from a single lamp controller; the signal output end of the first processing unit outputs modulated electric signals, and outputs the modulated electric signals to the at least one group of electric light sources so as to realize lamp control, wherein one group of electric light sources includes at least two electric light sources.
