Document Type and Number:
WIPO Patent Application WO/2019/021913
Kind Code:
A1
Abstract:
An optical unit (10), provided with: a light source (12); a first reflector (14) for reflecting emitted light (L), which has been emitted by the light source, at a first reflection region (R1) in which the reflection direction periodically changes; and a second reflector (16) for again reflecting first reflected light (L1), which has been reflected by the first reflector, at a second reflection region (R2) in which the reflection direction periodically changes. The first reflector (14) is configured so as to scan the second reflection region (R2) by the first reflected light (L1), and in the second reflector (16), the second reflection region (R2) is formed so as to scan second reflected light (L2) obtained by reflecting the first reflected light (L1) and thereby form a light distribution pattern.
