To provide a vehicular lighting fixture that makes illuminance of a road surface gradually uniform while inhibiting a decrease in light utilization efficiency, and a road surface drawing system.SOLUTION: A vehicular lighting fixture for applying light toward a road surface from a vehicle comprises: a plurality of light sources that are arranged in a direction orthogonal to a vehicle width direction; a light emission amount control part that individually changes the light emission amounts of the plurality of light sources; an image generation part that forms an image by modulating the light emitted from the light source; and a projection part that projects the light with the image to the road surface. The plurality of light sources each form a plurality of light distribution areas that are arranged toward a distant position from a position near the vehicle on the road surface.SELECTED DRAWING: Figure 2
【課題】光の利用効率の低下を抑止しつつ路面の照度を均一に近づける車両用灯具および路面描画システムの提供を目的とする。【解決手段】車両から路面に向けて光を照射する車両用灯具であって、車両の幅方向と直交する方向に配列された複数の光源と、複数の光源の発光量を個別に変更する発光量制御部と、光源から出射された光を変調して画像を形成する画像生成部と、画像を有する光を路面に投影する投影部と、を備え、複数の光源は、それぞれ路面上において車両の近傍から遠方に向かって並ぶ複数の配光領域を形成する、車両用灯具。【選択図】図2
