Title:
VEHICULAR LAMP AND VEHICULAR HEADLIGHT
Document Type and Number:
WIPO Patent Application WO/2021/015184
Kind Code:
A1
Abstract:
A vehicular headlight (1), serving as a vehicular lamp, comprises: a plurality of light emitting optical systems (30, 40) that emit light; and a reflection device (50) that includes a reflection control surface (53) constituted by reflection surfaces (54r) of a plurality of reflection elements (54) for which tilt states can be individually switched, and that reflects, by the reflection control surface (53), light (L1, L2) emitted respectively from the plurality of light emitting optical systems (30, 40) to form a light distribution pattern corresponding to the tilt states of the plurality of reflection elements (54). Of irradiation patterns (PF, PS) at the reflection control surface (53) of each of the lights (L1, L2) emitted respectively from the plurality of light emitting optical systems (30, 40) and projected on the reflection control surface (53), the intensity distributions of light of at least two of the irradiation patterns (PF, PS) differ from each other.
