Zusammenfassung:PROBLEM TO BE SOLVED: To provide a novel light emission element lighting device capable of suppressing electromagnetic noise and acoustic noise.SOLUTION: A light emission element lighting device is mounted in each light emission module of a luminaire having plural light emission modules. The light emission element lighting device is connected to a light emission element (3), and has current control circuits (20, 50, 60) for modulating current flowing in the light emission element (3) on the basis of an input dimming signal, and a dimming signal processing circuit (70) which receives the dimming signal through an input interface, inputs the dimming signal to the current control circuits (20, 50, 60) and outputs the dimming signal from an output interface while changing at least one of the ON-time timing and the period of the dimming signal.SELECTED DRAWING: Figure 3 【課題】電磁ノイズや音響ノイズの発生を抑制できる新規な発光素子点灯装置を提供する。【解決手段】ある実施形態における発光素子点灯装置は、複数の発光モジュールを備える照明装置における各発光モジュールに搭載される。発光素子点灯装置は、発光素子(3)に接続され、入力された調光信号に基づいて、発光素子(3)を流れる電流を変調させる電流制御回路(20、50、60)と、前記調光信号を入力インターフェースを介して受け取り、前記調光信号を電流制御回路(20、50、60)に入力し、かつ、前記調光信号のオン時間タイミングおよび周期の少なくとも一方を変化させて、前記出力インターフェースから送出する調光信号処理回路(70)とを備える。【選択図】図3
