Document Type and Number:
WIPO Patent Application WO/2023/067977
Kind Code:
A1
Abstract:
A first optical system (11) comprises a spatial light modulator (111) equipped with at least one light source (111a), and forms a low beam pattern (LP), which has a cut-off line (CL) at an upper end thereof, in an illumination target area (A) by using light emitted from the spatial light modulator (111). A control device (14) controls the operation of the spatial light modulator (111) in such a manner as to cause a first low-luminosity area having a relatively low luminosity to be formed within the low beam pattern (LP) on the basis of detection information (DT) indicative of the position of a specific illumination target body detected within the illumination target area (A) and also to cause the position and/or the size of the first low-luminosity area to change according to the relative position thereof with respect to said illumination target body.
