Title:
PROJECTION OPTICAL INSTRUMENT AND HEADLIGHT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/082177
Kind Code:
A1
Abstract:
A projection optical instrument (10) is provided with a light source unit (110), a projection optical member (120), and a support unit (160). The light source unit (110) emits light (L11). The projection optical member (120) converts the light (L11) emitted from the light source unit (110) into projection light (L12). The support unit (160) supports the projection optical member (120) so as to be capable of moving relative to the light source unit (110) in at least one direction orthogonal to the optical axis direction of the light source unit (110). Vibration is applied to the light source unit (110) and/or the projection optical member (120), whereby the projection optical member (120) vibrates relative to the light source unit (110) in the direction orthogonal to the optical axis direction of the light source unit (110).
