To provide a road surface illumination device and a road surface illumination method that can reduce or prevent dazzle and annoyance to a driver of a vehicle traveling on a road surface when the driving environment of the vehicle traveling on the road surface becomes wet.SOLUTION: When the driving environment of a vehicle C traveling on a road surface T becomes wet, illumination light B that is emitted toward an illumination area E divided into a plurality of segment areas S of the road surface T and that is emitted toward some of the segment areas S corresponding to the vehicle C traveling on the road surface T is partially shaded or dimmed.SELECTED DRAWING: Figure 1
【課題】路面を走行する車両の運転環境が湿潤状態となるときに、この路面を走行する車両のドライバーへの眩惑や煩わしさを緩和又は防止することを可能とした路面照射装置及び路面照射方法を提供する。【解決手段】路面Tを走行する車両Cの運転環境が湿潤状態となるときに、路面Tの複数のセグメント領域Sに分割された照明領域Eに向けて照射される照明光Bのうち、路面Tを走行する車両Cに対応した一部のセグメント領域Sに向けて照射される照明光Bを部分的に遮光又は減光する。【選択図】図1
