To achieve the light distribution of a vehicle headlight, capable of improving a driver's visual responsiveness during nighttime traveling.SOLUTION: There is provided a vehicle head light 2 comprising: first light distribution means which radiates light toward a road surface 130 ahead of a vehicle, and which forms a first light distribution pattern 71 having a hot zone 73 in a central part in a vehicle width direction; and second light distribution means which radiates light toward a roadside ahead of the vehicle, and which forms a second light distribution pattern 81 having a hot zone 83 at a position offset outward in the vehicle width direction from the hot zone of the first light distribution pattern, in an area overlapping with the first light distribution pattern 71. The radiation range of light by the second light distribution means to an object on the roadside has an upper edge part 140 extending forward of the vehicle in a direction inclined inward in the vehicle width direction.SELECTED DRAWING: Figure 6
【課題】夜間走行時における運転者の視覚応答性の向上を図り得る車両用前照灯の配光を実現する。【解決手段】車両前方の路面130に向けて光を照射するように構成され、車幅方向の中央部にホットゾーン73を有する第1配光パターン71を形成する第1配光手段と、車両前方の沿道に向けて光を照射するように構成され、前記第1配光パターンのホットゾーンから車幅方向外側にオフセットした位置にホットゾーン83を有する第2配光パターン81を、前記第1配光パターン71と重複するエリアに形成する第2配光手段とを備え、前記第2配光手段による沿道上の物体に対する光の照射範囲は、車両前方に向かって車幅方向内側に傾斜した方向に延びる上縁部140を有する車両用前照灯2を提供する。【選択図】図6
