The present invention provides a lighting device. The lighting device provides an output voltage to loads for lighting and comprises: a converter for generating the output voltage, using a driving signal; and a driving circuit for changing the form of an oscillation signal, performing a frequency dithering for the driving signal generated using the oscillation signal, and providing the driving signal, the frequency of which has been dispersed by the frequency dithering. La présente invention concerne un dispositif d'éclairage. Le dispositif d'éclairage fournit une tension de sortie à des charges en vue d'éclairage et comprend : un convertisseur permettant de générer la tension de sortie, à l'aide d'un signal d'attaque; et un circuit d'attaque permettant de changer la forme d'un signal d'oscillation, d'exécuter un tramage de fréquence pour le signal d'attaque généré en utilisant le signal d'oscillation, et de fournir le signal d'attaque, dont la fréquence a été dispersée par le tramage de fréquence. 본 발명은 조명 장치를 개시하며, 상기 조명 장치는 조명용 부하들에 출력 전압을 제공하며, 구동 신호를 이용하여 상기 출력 전압을 생성하는 컨버터 및 발진 신호의 형태를 변화시켜서 상기 발진 신호를 이용하여 생성하는 상기 구동 신호에 대한 주파수 디더링을 수행하고, 상기 주파수 디더링에 의하여 주파수가 분산된 상기 구동 신호를 제공하는 구동 회로를 포함한다.
