The present disclosure provides an AC-direct-type LED-lighting device including compensation circuit for AC input compensation, including a compensation inductor and first compensation capacitor parallelly connected to one terminal of AC input and a second compensation capacitor connected in series; rectifying unit for rectifying output from second compensation capacitor terminals to obtain direct current; and LED array driven by the rectifying unit output, wherein capacities of the first and second compensation capacitors and the compensation inductor and LED array output voltage are determined to cause 0.9 or larger cosine value of a phase, with respect to the AC input voltage, of resulting current obtained by dividing AC input voltage by sum of (i) parallel value of an equivalent impedance Re of the rectifying unit and LED array and an impedance of the second compensation capacitor and (ii) parallel value of impedances of the compensation inductor and first compensation capacitor.
