The invention relates to an optical device for a vehicle headlamp, which comprises a light source, a primary optical unit, a secondary optical unit and a shading plate which is arranged between the primary optical unit and the secondary optical unit in the advancing direction of a vehicle and extends along the horizontal direction. The light source and the primary optical unit are placed in the direction right opposite to the secondary optical unit, so that most of light beams generated by the light source penetrate through the primary optical unit and are parallel to the vehicle advancing direction or the extending direction of the shading plate to be emitted to the secondary optical unit. The invention also relates to a headlamp and a vehicle.

    本发明涉及一种用于车辆前照灯的光学设备,其包括光源、初级光学单元、次级光学单元以及在车辆前进方向上位于所述初级光学单元和所述次级光学单元之间的、沿水平方向延伸的遮光板,其特征在于,所述光源和所述初级光学单元正对所述次级光学单元的方向放置,使得所述光源产生的大部分光束穿过所述初级光学单元平行于车辆前进方向或者所述遮光板的延伸方向射至所述次级光学单元。本发明还涉及一种前照灯和一种车辆。
