LED DRIVE APPARATUS FOR CONTINUOUS DRIVING OF LED, LED LUMINESCENT APPARUTUS COMPRISING THE SAME AND DRIVING METHOD THEREOF

摘要

The present invention provides an LED driving circuit including an LED driving module for providing an LED light emitting module including first to n-th LED groups (n is an integer of 2 or more) with a first driving voltage of which a voltage value changes over time, of which a minimum voltage value is at least Vf1 or less, and of which a maximum voltage value is at least Vfn or more, and sequentially driving the first to n-th LED groups according to a voltage level of the first driving voltage; and a second driving voltage provision module for storing a part of the first driving voltage, and selectively providing the LED groups at least other than the first to m-th LED groups of the LED groups with a second driving voltage in a Vfm compensation section (1<=m<=n-1) under the control of the LED driving module, wherein the second driving voltage provision module includes a plurality of energy charging/discharging elements, the plurality of energy charging/discharging elements are charged by receiving a part of the first driving voltage in series, and the second driving voltage is provided in parallel in a discharging mode.
