Abstract
A light-emitting diode (LED) driving apparatus driving an LED module includes: a first output circuit configured to supply a first driving current to a first LED array; a second output circuit configured to supply a second driving current to a second LED array; and a controller configured to transmit a first control signal and a second control signal respectively to the first output circuit and the second output circuit, wherein the controller is further configured to control the LED module based on the first input signal so that a color temperature of the LED module has a value between a first color temperature and a second color temperature, to control brightness of the LED module based on the second input signal, and includes a lookup table including information about the first control signal and the second control signal respectively corresponding to the first input signal and the second input signal.
