OPTICAL UNIT AND VEHICULAR LIGHTING |
摘要 |
The optical unit (120) is provided with a light source (112), a rotating reflector (140) rotating around a rotation axis, and a projection lens (130) having an entrance surface (130b) wherefrom reflected light from the rotating reflector (140) enters. In a circumferential direction to the rotation axis, the rotating reflector (140) has a plurality of blades (142), each having a reflective surface for reflecting light emitted from the light source during a rotation for a predetermined angle to form a desired light distribution pattern. A shade (160) is provided between the projection lens (130) and the rotating reflector (140). Light that enters the projection lens (130) exit surface (130a) with a predetermined angular range and is focused by the projection lens to be directed toward the rotating reflector (140) reflective surface is at least partially blocked by the shade (160). |
