LED driving circuit for continuously driving LED, LED lighting device comprising same and driving method
Abstract:
An exemplary embodiment discloses a light-emitting diode (LED) driving circuit including an LED driving module configured to provide a first driving voltage to an LED light emitting module including a first LED group to an n-th LED group, n is an integer which is equal to or larger than 2, and sequentially drive the first LED group to the n-th LED group depending on a voltage level of the first driving voltage and a second driving voltage providing module configured to store some of the first driving voltage and selectively provide a second driving voltage to some of the LED groups other than at least the first LED group to an m-th LED group among the LED groups in a Vfm compensation section, 1≦m≦n−1, according to a control of the LED driving module.
