Abstract
The present invention provides a lighting device. The lighting device comprises a driving circuit therefor, which provides a switching driving signal of a converter, wherein the driving circuit comprises: an end time point generation unit for generating a control pulse which expresses an end time point of a minimum on-time according to a frequency change of an oscillation signal used to generate the driving signal, within a turn-on interval of the converter; and a minimum on-time determination unit for providing, within a turn-on interval of the converter, a minimum on-time pulse which defines the minimum on-time including a time from a turn-on start time point of the converter to the end time point, using the control pulse.
