PROBLEM TO BE SOLVED: To provide a lighting device capable of reducing current consumption, a lighting fixture, and a vehicle including the same.SOLUTION: A light source unit 100 comprises a light source 110, and a load information output unit 120 which outputs load information indicating light-emitting characteristics of the light source 110 when power is supplied. A lighting device 1 comprises a current output unit 10, a load characteristic capture unit 20, and a control unit 30. The current output unit 10 supplies current to the light source 110 of the light source unit 100. The load characteristic capture unit 20 captures load information from the load information output unit 120 by supplying power to the load information output unit 120 of the light source unit 100. The control unit 30 controls the current supplied from the current output unit 10 to the light source 110 on the basis of the load information captured by the load characteristic capture unit 20. The load characteristic capture unit 20 supplies power to the load information output unit 120 only when load information is captured. When the load information is not captured, the load characteristic capture unit does not supply power to the load information output unit 120.SELECTED DRAWING: Figure 1

    【課題】消費電流を低減することができる点灯装置、照明器具、及びそれを備える車両を提供する。【解決手段】光源ユニット100は、光源110と、電力が供給されたときに光源110の発光特性を示す負荷情報を出力する負荷情報出力部120とを備えている。点灯装置1は、電流出力部10と負荷特性取込部20と制御部30とを備える。電流出力部10は光源ユニット100の光源110に電流を供給する。負荷特性取込部20は、光源ユニット100の負荷情報出力部120に電力を供給することによって、負荷情報出力部120から負荷情報を取り込む。制御部30は、負荷特性取込部20によって取り込まれた負荷情報に基づいて、電流出力部10から光源110に供給される電流を制御する。負荷特性取込部20は、負荷情報を取り込む取込時のみ負荷情報出力部120に電力を供給し、取込時以外は負荷情報出力部120に電力を供給しない。【選択図】図1
