Abstract: An LED control system using a modulated signal includes a computer, a data storage unit, an AC power, a power conversion circuit, a control circuit, and an LED lamp string. The AC power is converted into a DC power by the power conversion circuit to supply a DC voltage to the control circuit and the LED lamp string. A computer control data is sent to the control circuit through the data storage unit by a user using the computer. The computer control data is modulated to a modulated signal by the control circuit. The modulated signal is sent to the LED lamp string with the same transmission line sending the DC voltage. The light of the LED lamp string is changed according to the modulated signal. The cost is reduced because the DC voltage and the modulated signal are sent in the same transmission line.
