To improve visibility.SOLUTION: A light source of a vehicular lighting system includes three or more kinds of light-emitting devices which emit visible lights having different main wavelengths due to input of power. The vehicular lighting system emits to an irradiation target place, a mixed color light generated by mixing visible lights emitted from the light-emitting devices. A control part of the vehicular lighting system controls the input power to the light-emitting devices according to a brightness around the irradiation target place so as to switch the main wavelength of the mixed color light. When a brightness around the irradiation target place is larger than a reference value (step S130: YES), the control part inputs power to the light-emitting devices (step S140) so that the main wavelength of the mixed color light becomes a first main wavelength. When the brightness is a reference value or less (step S130: NO), the control part inputs power to the light-emitting devices (step S150) so that the main wavelength of the mixed color light becomes a second main wavelength shorter than the first main wavelength.SELECTED DRAWING: Figure 5

    【課題】視認性の向上を図る。【解決手段】車両用照明装置の光源は、電力が投入されることにより、互いに主波長の異なる可視光を放射する少なくとも3種類の発光デバイスを備える。車両用照明装置は、各発光デバイスから放射される可視光を混色させて生成した混色光を、照射対象箇所に照射する。車両用照明装置の制御部は、照射対象箇所の周囲の明るさに応じて、各発光デバイスへの投入電力を制御することで、混色光の主波長を切り替える。制御部は、照射対象箇所の周囲の明るさが基準値よりも大きい場合(ステップS130:YES)には、混色光の主波長が第1主波長となるように、各発光デバイスに電力を投入する(ステップS140)。上記明るさが基準値以下の場合(ステップS130:NO)には、混色光の主波長が上記第1主波長よりも短い第2主波長となるように、各発光デバイスに電力を投入する(ステップS150)。【選択図】図5
