Provided is vehicle lighting having a function for drawing on the road surface and having a simple structure, the vehicle lighting having a headlight function or an indicator light function, as well as the function for drawing on the road surface. The vehicle lighting comprises one light source. An optical unit functions as a headlight or an indicator light, and shapes a part of the light emitted from the light source into a predetermined light distribution and emits the same. A road surface drawing unit, which has a function for drawing on the road surface, shapes another part of the light emitted from the light source into a drawing pattern related to the illumination objective of the optical unit, and projects the drawing pattern onto the road surface. Since the one light source is used as the common light source for the optical unit and the road surface drawing unit, the vehicle lighting has a simple structure and is functionally very effective because of the emission of light having a related objective.
提供一种构成简单的、具备路面描绘功能的车辆用灯具,其具备前照灯或者信标灯的功能与路面描绘功能这两方的功能。在除了具备作为前照灯或者信标灯的功能之外还具备路面描绘功能的车辆用灯具中,具备一个光源并起到作为前照灯或者信标灯的功能的光学单元将光源的出射光的一部分形成为规定的配光而照射,起到向路面描绘的功能的路面描绘单元将光源的出射光的另一部分形成为与光学单元的照射目的相关联的描绘图案而向路面投影。由于将一个光源用作光学单元与路面描绘单元共用的光源,因此构成简单,并且通过使目的相关联的照射,功能效果较高。
