摘要
Disclosed are a light emitting diode (LED) driver circuit having improved flicker performance and an alternating current-driving type LED lighting device including the same. The LED driver circuit can remove an LED off period using a charging and discharging circuit during a compensation period so as to reduce light output deviation of an LED lighting device, and provide a driving voltage to another element of the LED lighting device, using the charging and discharging circuit during an additional discharging period so as to simultaneously improve power efficiency.
