Abstract
An LED lighting device using a ballast may be provided that includes: an LED unit which includes at least one LED device; a rectifier which rectifies a current power signal output from the ballast; and a current driving unit which receives an output current of the rectifier and controls the power which is transmitted from the ballast to the LED unit. The current driving unit transmits current which has a magnitude greater than that of the output current of the rectifier to the LED unit.
