Abstract
A road surface drawing lamp is configured to be mounted on a vehicle. The road surface drawing lamp is configured to draw a sequential light pattern in which an irradiation region changes in a sequential manner in a drawing region set in a surrounding region of the vehicle. The road surface drawing lamp is configured to first form, as the sequential light pattern, a first light pattern which is drawn at least in a part including a tip portion of the drawing region.
Claims6
A road surface light drawing method, comprising:
- drawing a light pattern on a road surface by a drawing lamp configured to be mounted on a vehicle;
- wherein an irradiation region of the light pattern changes in a drawing region set in a surrounding region of the vehicle, the drawing region including a farthest region provided at part including a tip portion of the drawing region farthest from the vehicle, a nearest region closest to the vehicle, and one or more intermediate regions between the farthest region and the nearest region, the farthest region being irradiated by a third light source, the nearest region being irradiated by a first light source, and the one or more intermediate regions being irradiated by a second light source,
- wherein a first light pattern, in which far light is drawn at least in the farthest region by the third light source and near light is drawn at least in the nearest region by the first light source but no intermediate light is drawn in the one or more intermediate regions by the second light source, is formed first as the light pattern, and;
- wherein a second light pattern, in which the near light is drawn at least in the nearest region by the first light source, intermediate light is drawn in at least one of the one or more intermediate regions by the second light source, and the far light is drawn in the farthest region by the third light source, is second formed as the light pattern,
- wherein the far light drawn by the third light source is maintained in at least the farthest region during the entire light pattern, and
- wherein the near light drawn in the nearest region, the intermediate light drawn in the one or more intermediate regions, and the far light drawn in the farthest region extend in a line from the vehicle to the tip portion.
