Abstract: Disclosed is a control circuit of an LED lighting apparatus having a dimming function. The control circuit provides a current path corresponding to light emitting states of LED channels in response to a rectified voltage, and performs dimming by controlling a current amount of the current path in response to a dimming control signal provided as an analog signal or digital signal.

Abstract: Disclosed is a control circuit of an LED lighting apparatus, which compensates for power for light emission of a lamp including LEDs. The control circuit can generate a compensation signal corresponding to change of power provided to the lamp, and uniformly maintain the power by controlling a current provided to the lamp in response to the compensation signal. Thus, the control circuit can compensate for the power change of the lamp due to a power supply environment factor in a building, region, or country or a temporarily unstable power supply environment factor, such that the lamp can emit light at uniform luminance.
