Abstract

The present invention provides a lighting device. The lighting device provides an output voltage to loads for lighting and comprises: a converter which provides the output voltage to the loads, using a driving signal; and a driving circuit which generates a control voltage having a level corresponding to a change in the entire amount of the loads at a time point of a load amount change and provides the driving signal having an on-time, which has been adjusted to correspond to the control voltage, at the time point of the load amount change.
