ABSTRACT:
Provided are an apparatus for controlling a lamp driving, and a light unit. The apparatus comprises a trans-portion, a plurality of lamps, a first cable, and a current attenuator. The trans-portion outputs a first AC power and a second AC power. The plurality of lamps are lighted-on by the first and second AC powers. The first cable and a second cable transfer an output power from the transformer to both ends of the lamps. The current attenuator removes a deviation in currents input to both ends of the lamps.
