Classification: CPC H | IPC H

Claim 8:
9. A light emitting diode (LED) lighting apparatus comprising:
a first LED array configured to emit first light having a first brightness or a first color temperature;
a second LED array configured to emit second light having a second brightness or a second color temperature;
a driving chip directly connected to the first LED array and the second LED array, and configured to receive AC power, and to control a first driving current of the first LED array and a driving current of the second LED array;
a first switching circuit configured to selectively provide the AC power to the first LED array based on a first control signal having a first Pulse Width Modulation (PWM) control signal;
a second switching circuit configured to selectively provide the AC power to the second LED array based on a second control signal having a second PWM control signal;
a communication device directly connected to the driving chip, and configured to receive DC power and to generate the first control signal and the second control signal based on a request received from an external device; and
an AC/DC converter configured to receive the AC power, and to provide the DC power to the communication device.
