Description
Claims (1)
- 光源と光学レンズとを備え、光源からの直射光を光学レンズの光学面を介して前方に照射する車両用前照灯ユニットにおいて、
前記光学レンズの前記光学面以外の周縁部の少なくとも一部には、前記周縁部がカットされた平坦面が形成され、
前記光学レンズの前記平坦面から出射された光を前方に反射させる反射部材が、光学レンズの周囲の少なくとも一部に設けられ、
前記反射部材は導光体からなり、前記平坦面に対向する入射面と、前記入射面から前記導光体に入った光を内面反射する傾斜面と、前記傾斜面で内面反射された前記光を出射する出射面とを有していて、前記導光体の内面を利用して前記光を前方に拡散させて出射させることを特徴とする車両用前照灯ユニット。
