AC direct LED driver including capacitor for LED driver

A light emitting diode (LED) driving apparatus comprising:

• a rectifier configured to receive and rectify an alternating current (AC) voltage;
• an LED configured to emit light based on a rectified voltage received from the rectifier;
• a capacitor connected to a first terminal of the LED, and configured to drive the LED while alternating between charging and discharging sections according to a preset cycle;
• a first current driver connected to a second terminal of the LED and configured to control a path of current flowing in the LED and the capacitor based on different input voltage levels;
• a second current driver configured to control charging and discharging of the capacitor;
• and
• a first diode connected onto a current path of the capacitor and the second current driver, and configured to form a discharging path for driving the LED based on a charged voltage of the capacitor,
• wherein the first diode provides a discharging path of the capacitor, is turned on when the input voltage is lower than voltage stored in the capacitor, and provides a current path for allowing the first current driver to drive the LED.
