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. La présente invention concerne un dispositif d'éclairage. Le dispositif d'éclairage fournit une tension de sortie à des charges en vue d'éclairer et comprend : un convertisseur qui fournit la tension de sortie aux charges, à l'aide d'un signal d'attaque; et un circuit d'attaque qui génère une tension de commande ayant un niveau correspondant à un changement de la quantité totale des charges au moment d'un changement de quantité de charge et fournit le signal d'attaque ayant une durée de mise sous tension, qui a été ajustée pour correspondre à la tension de commande, au moment du changement de la quantité de charge. 본 발명은 조명 장치를 개시하며, 상기 조명 장치는 조명용 부하들에 출력 전압을 제공하며, 구동 신호를 이용하여 상기 부하들에 상기 출력 전압을 제공하는 컨버터 및 부하량 변화 시점에 상기 부하들의 전체 부하량 변화에 대응하는 레벨의 제어 전압을 생성하고, 상기 부하량 변화 시점에 상기 제어 전압에 대응하도록 조절된 온 시간(On Time)을 갖는 상기 구동 신호를 제공하는 구동 회로를 포함한다.
