To provide a vehicular lighting tool having a road surface drawing function which has both a function of a head lamp or a marker lamp and a road surface drawing function, and has a simple structure.SOLUTION: The vehicular lighting tool having a road surface drawing function in addition to a function of a head lamp and a marker lamp includes: an optical unit having one light source and playing a function of a head lamp or a marker lamp, forming a part of emitted light of the light source into predetermined light distribution and emitting the emitted light; and a road surface drawing unit forming a road surface drawing function which forms other part of the emitted light of the light source into a drawing pattern relating to an irradiation purpose of the optical unit and projects the emitted light onto a road surface. The one light source is used as a common light source of the optical unit and the road surface drawing unit, and the lighting tool has a simple structure, and has a high function effect by purpose-related irradiation.SELECTED DRAWING: Figure 1
【課題】前照灯又は標識灯の機能と、路面描画機能の両方の機能を備え、構成がシンプルな路面描画機能を備えた車両用灯具を提供する。【解決手段】前照灯または標識灯としての機能に加えて、路面描画機能を備えた車両用灯具であり、1の光源を備え、前照灯または標識灯としての機能を成す光学ユニットは、光源の出射光の一部を所定の配光に形成して照射し、路面への描画機能を成す路面描画ユニットは、光源の出射光の別の一部を、光学ユニットの照射目的と関連した描画パターンに形成して路面に投影する。1の光源を光学ユニットと路面描画ユニットの共通の光源として使用するため、構成がシンプルで、かつ目的を関連させた照射により、機能効果が高い。【選択図】図1
