LIGHTING FIXTURE FOR ROAD SURFACE DRAWING, AND LIGHTING FIXTURE FOR ROAD SURFACE DRAWING FOR VEHICLE
To provide a lamp for people and a lamp for a vehicle for supporting smooth traffic.SOLUTION: There are provided road surface drawing lighting fixtures 10a to 10c for irradiating a road surface with light. The road surface drawing lighting fixtures 10a to 10c are each provided with a light source 12. Therein, when D0 is a distance from a light source 12 to an irradiated point P where an optical axis C of the light source 12 intersects the road surface, a parallel distances Dx is a component parallel to the road surface at the distance D0, and a perpendicular distance Dy is a component perpendicular to the road surface at the distance D0, the light sources 12 are provided at positions where the parallel distances Dx are 0.5 to 1.5 m and the perpendicular distances Dy are 0.4 to 1.0 m.SELECTED DRAWING: Figure 3
【課題】円滑な交通を支援する対人用ランプおよび車両用ランプを提供することを目的とする。【解決手段】路面に光を照射する路面描画用灯具１０ａ～１０ｃであって、路面描画用灯具１０ａ～１０ｃは、光源１２を備えており、光源１２から光源１２の光軸Ｃが路面と交差する地点である照射地点Ｐまでの距離をＤ０、距離Ｄ０における路面と平行な成分である平行距離Ｄｘ、距離Ｄ０における路面と垂直な成分である垂直距離Ｄｙとすると、光源１２は、平行距離Ｄｘが０．５ｍ～１．５ｍ、垂直距離Ｄｙが０．４ｍ～１．０ｍとなる位置に設けられている。【選択図】図３
