To provide a vehicular lighting apparatus capable of ameliorating a problem in which a pedestrian is overlooked by a driver, even under adverse conditions such as night and rainy weather.SOLUTION: A vehicular lighting apparatus 1 comprises: a low-beam irradiation part (a low-beam unit 7) which illuminates a lower irradiation region (a low-beam irradiation region 11) on a lower side ahead of a vehicle 2; a pattern irradiation part (a projector unit 8) which irradiates, with irradiation light, a lateral irradiation region (a right-side pattern irradiation region 12) on a lateral side of a traveling road of the vehicle 2 in an irradiation pattern such that bright regions 13 and dark regions 14 are alternately repeated; an environmental information acquisition device 20 which acquires information about a moisture environment around the vehicle 2; and a control part (a lamp control ECU 9) which changes an irradiation mode of the low-beam irradiation part 7 or/and the pattern irradiation part 8 on the basis of the information acquired by the environmental information acquisition device 20. In one mode, in rainy weather at night, the control part 9 causes the low-beam irradiation part 7 to reduce brightness of irradiation light, and causes the pattern irradiation part 8 to increase brightness of irradiation light.SELECTED DRAWING: Figure 2
【課題】夜間でかつ雨天であるといった悪条件の下でも運転者による歩行者の見落としを改善できる車両用照明装置を提供すること。【解決手段】車両用照明装置1は車両2前方下側の下部照射領域(ロービーム照射領域11)を照らすロービーム照射部(ロービームユニット7)と、明領域13と暗領域14が交互に繰り返される照射パターンで車両2の走行路側方の側方照射領域(右側パターン照射領域12)に照射光を照射するパターン照射部(プロジェクターユニット8)と、車両2の周囲の水分環境に関連する情報を取得する環境情報取得デバイス20と、環境情報取得デバイス20が取得した情報に基づいてロービーム照射部7または/およびパターン照射部8の照射態様を変更する制御部(灯具制御ECU9)とを備える。一つの態様では、制御部9は、夜で雨天の時、ロービーム照射部7に照射光を減光させ、パターン照射部8に照射光を増光させる。【選択図】図2
