Claim Text:
1. An integrated light-emitting diode driver circuit, comprising: a bi-directional power line communication unit comprising a microcontroller, the microcontroller being configured to receive an AC voltage and a conversion voltage as an operation voltage of the microcontroller, and to generate a voltage signal based on the AC voltage, the bi-directional powerline communication unit being configured to convert the voltage signal to generate a modulation signal and to generate a light-dimming control signal based on the modulation signal; a power conversion module configured to receive the AC voltage and to convert the AC voltage to generate an output voltage; and a constant current/constant voltage control unit configured to receive the light-dimming control signal and to generate a constant light-dimming current or a constant light-dimming voltage, wherein the integrated light-emitting diode driver circuit is configured to output the constant light-dimming current or the constant light-dimming voltage and to output the output voltage to drive a light-emitting diode string configured to be driven by the light-emitting diode driver circuit.
