Abstract

A power factor compensation type LED lighting apparatus according to one embodiment of the present invention provides an LED lighting apparatus comprising: a compensation circuit including a connective terminal provided at both end portions thereof to be coupled with a socket of a rapid start type stabilizer,and a serial inductance-capacitance element serially connected to an inductance element and a capacitance element to be connected between the connective terminal of one end portion and the connective terminal of the other end portion among both end portions; and an LED load circuit including a rectification circuit connected to both ends of the capacitance element to rectify the AC current of the both ends of the capacitance element to DC current, and an LED module connected to both ends of the rectification circuit to be driven by the received DC current.
