1. An AC source direct driving LED lighting device comprising:
a light emitting unit which has a first electrolytic capacitor and receives a rectified AC voltage to adjust a first constant current and emits LED arrays;
a charging/discharging unit which receives the adjusted first constant current to be adjusted to second to fourth constant currents and charges/discharges embedded second to fourth electrolytic capacitors, respectively;
a discharge LED path unit which forms a path of discharging the voltage charged in the charging/discharging unit to the light emitting unit; and
a current driving unit which receives the adjusted first to fourth constant currents to form first to fourth channels using first to fourth reference voltages and controls current transfer.
