Title:
VEHICULAR MICROLENS ARRAY, AND VEHICULAR LAMP IN WHICH SAME IS USED
Document Type and Number:
WIPO Patent Application WO/2021/060200
Kind Code:
A1
Abstract:
This vehicular microlens array (10) has a plurality of optical systems (20). Each of the optical systems (20) has an incidence-side lens part (21) and an exit-side lens part (22) that are provided as a pair, and a light-shielding body (23). The optical systems (20) are adjacent in a direction orthogonal to an optical axis Ax, and are integrated. Each of the light-shielding bodies (23) has a first light-shielding surface (24) that extends in a direction orthogonal to the optical axis Ax of the incidence-side lens part (21) and that has a shape corresponding to a specific light distribution pattern, and a second light-shielding surface (25) that extends in a direction orthogonal to the first light-shielding surface (24) and that shields cross-talk light incident from the adjacent optical systems (20).
