Claims (2)
- 有機EL素子を光源とする発光モジュールを点灯させるための電力を出力する電源部と、
前記発光モジュールへの供給電流の電流値を指示する調光信号が入力される調光信号入力部と、
前記調光信号入力部に入力された調光信号に従った電流値の出力電流を前記発光モジュールに供給するように前記電源部を制御する制御部とを備え、
前記制御部は、前記調光信号に従って前記電源部の出力電流の電流値を変更する前に、前記電源部の出力電流の電流値を、前記変更の前後の出力電流の電流値に挟まれた範囲外の電流値とする過渡動作を行い、
前記制御部は、前記過渡動作の後の電流値が前記過渡動作の前の電流値よりも低い場合には、前記過渡動作中は前記電源部の出力電流の電流値を前記過渡動作の前の電流値よりも高くした後で前記過渡動作の後の電流値よりも低くし、
前記過渡動作の後の電流値が前記過渡動作の前の電流値よりも高い場合には、前記過渡動作中は前記電源部の出力電流の電流値を前記過渡動作の前の電流値よりも低くした後で前記過渡動作の後の電流値よりも高くすることを特徴とする有機EL点灯装置。 - 請求項1記載の有機EL点灯装置と、前記有機EL点灯装置と前記有機EL点灯装置の前記電源部によって電流を供給される前記発光モジュールとをそれぞれ保持する器具本体とを備えることを特徴とする照明器具。
