Abstract
A light emitting diode control circuit with carrier signal control includes a signal coupling unit, an operational amplifier, a demodulation unit, an identification and control logic unit, a counting and shift-registering unit, a data register, an output register, at least a current output unit, an address encoding unit, an address register, a voltage regulator and an oscillator. The efficiency of the present invention is to reduce the transmission lines of the light emitting diode lamp. Therefore, the cost of the light emitting diode lamp is reducing.
