Abstract
Disclosed are a control circuit and a voltage generation method of an LED lighting apparatus which provides lighting using a rectified voltage. Light emission of the LED lighting apparatus can be implemented through current regulation, a rectified voltage used for light emission can be used to provide a constant voltage required for a peripheral circuit, and a current flowing through a current path formed by the current regulation can be controlled to perform dimming.
