Abstract: A lamp string controlling device includes a power supply circuit constituted by a transformer and a rectification circuit for converting an alternate current into a direct current. A harmonic oscillation circuit is connected between the transformer and the rectification circuit for eliminating noise and electromagnetic interference. A single chip based control circuit is connected between the power supply circuit and a driver circuit which drives a lamp string. The control circuit controls the lighting status of the lamp string between a full load condition and a non-full load condition in a variety of styles. A timing circuit having a time constant is coupled to the control circuit for switching the lamp string from a full load condition to the non-full load condition after a time period determined by the time constant thereof whereby overall power consumption of the lamp string may be lowered down and thus a small-sized transformer suffices for the operation of the lamp string. Therefore a compact lamp string controlling device may be formed by combining the power supply circuit and the control circuit together. A manual switch and a remote control module may be coupled to the control circuit for manual and remote control.
