Provided is a road surface drawing device that irradiates road surface drawing patterns (P1, P2) on a road surface. The road surface drawing device includes a light source (5) and an optical member that irradiates light emitted from the light source (5) to a road surface. The road surface drawing patterns (P1, P2) are elongated in a direction away from the road surface drawing device. The optical member deflects the light emitted from the light source (5) such that, in a direction (D2) orthogonal to the longitudinal direction (D1) of the road surface drawing patterns (P1, P2), the illuminance at the edge parts of the road surface drawing patterns (P1, P2) is higher than the illuminance at the center parts of the road surface drawing patterns (P1, P2).

    一种向路面照射路面描绘图案(P1、P2)的路面描绘装置。路面描绘装置具有光源(5)和使从光源(5)射出的光照射到路面的光学部件。路面描绘图案(P1、P2)是在远离路面描绘装置的方向上细长的形状。光学部件使从光源(5)射出的光偏斜,以使得在与路面描绘图案(P1、P2)的长度方向(D1)正交的方向(D2)上,路面描绘图案(P1、P2)的边缘部的照度比路面描绘图案(P1、P2)的中心部的照度高。
