Abstract
A road surface drawing lamp unit includes a light source module and an optical system. In the light source module, a plurality of light sources which correspond individually to drawing patterns, each of which is long in a first direction which is a width direction of a road and short in a second direction which intersects the width direction of the road and an emitting axis of the light sources, are arranged so that the drawing patterns are drawn at a plurality of locations on the road along the second direction, and the light sources are formed so as to be turned on and off independently. The optical system emits light emitted from the light sources to the front.
