To stably and accurately control light distribution of an irradiation beam.SOLUTION: A vehicular lighting fixture includes two lamp units, each of which has a first light source for emitting an irradiation beam (a visible light), a second light source which emits an infrared light for sensing with a different peak wavelength from the first light source, and a light receiving part which detects intensity of a reflected light of the infrared light emitted from the second light source. Distribution of the light emitted from the first light source is controlled depending on the intensity of the reflected light which is detected by the light receiving part. The peak wavelength of the light emitted from the second light source of the first lamp unit is different from the peak wavelength of the light emitted from the second light source of the second lamp unit.SELECTED DRAWING: Figure 10
【課題】照射ビームの配光制御を安定して精度よく行う。【解決手段】車両用灯具は、照射ビーム(可視光)を出射する第1光源、第1光源とピーク波長の異なるセンシング用の赤外光を出射する第2光源、及び第2光源から出射した赤外光の反射光の強度を検出する受光部、を有する2つのランプユニットを備える。第1光源から出射する光は受光部が検出した反射光の強度に応じて配光制御され、第1のランプユニットの第2光源から出射する光のピーク波長と、第2のランプユニットの第2光源から出射する光のピーク波長とが異なる。【選択図】図10
