To provide a vehicular lighting apparatus having no possibility of impairing characteristics for visual recognition of a pedestrian on a driver side, while suppressing dazzling on the pedestrian side.SOLUTION: A vehicular lighting apparatus 1 comprises: a low-beam irradiation part 7 which illuminates a lower irradiation region (a low-beam irradiation region 11) on a lower side ahead of a vehicle 2; a high-beam irradiation part 6 which illuminates an upper irradiation region (a high-beam irradiation region 10) on an upper side and on a vehicle width direction center side relative to the lower irradiation region 11; and 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. The pattern irradiation part 8 irradiates, with irradiation light, an upper pattern irradiation region 17 on an upper side of the lateral irradiation region 12 in a predetermined first mode, and irradiates, with irradiation light, a lower pattern irradiation region 18 on a lower side of the lateral irradiation region 12 in a second mode different from the first mode.SELECTED DRAWING: Figure 6
【課題】歩行者側における眩惑を抑制しつつ、運転者側における歩行者視認のための特性が減殺されるおそれがない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7と、下部照射領域11よりも上側かつ車幅方向中央側の上部照射領域(ハイビーム照射領域10)を照らすハイビーム照射部6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)とを備え、パターン照射部8は、側方照射領域12のうちの上側の上部パターン照射領域17に所定の第1の態様で照射光を照射し、側方照射領域12のうちの下側の下部パターン照射領域18に第1の態様とは異なる第2の態様で照射光を照射する。【選択図】図6
