Summary:PROBLEM TO BE SOLVED: To provide a lighting device and an illumination device capable of reducing the influence of switching noise.SOLUTION: A control device is mounted on a substrate, arranged between a first lighting circuit and a second lighting circuit and controls the first lighting circuit and the second lighting circuit. When a first light-emitting element and a second light-emitting element are turned on the same degree of dimming, the control device switches a first switching element and a second switching element at frequencies different from each other.SELECTED DRAWING: Figure 6 【課題】スイッチングノイズの影響を低減することができる点灯装置および照明装置を提供する。【解決手段】制御装置は、基板上に実装され、第１点灯回路と第２点灯回路との間に配置され、第１点灯回路および第２点灯回路を制御する。制御装置は、第１発光素子と第２発光素子を同じ調光度で点灯する場合に、第１スイッチング素子と第２スイッチング素子とを互いに異なる周波数でスイッチングする。【選択図】図６
