Abstract
An LED lighting apparatus is configured to light in response to an input power signal. The LED lighting apparatus includes a power supply module, configured to receive the input power signal in order to generate a driving power signal, and an LED module configured to light in response to the driving power signal. The power supply module comprises a demodulating circuit configured to receive the input power signal and demodulate the received input power signal, in order to generate a dimming control signal for controlling luminance of the LED module, wherein the demodulating circuit demodulates the input power signal based on a phase-cut angle of the input power signal.
