Document Type and Number:
Japanese Patent JP7438022
Kind Code:
B2
Abstract:
An objective of the present invention is to achieve a reduction in glare caused by light-reflecting objects while simultaneously preventing a reduction in the visibility of light-reflecting objects. A light distribution control device 4 comprises a calculation unit 14 that calculates the size as seen from an own vehicle of a light-reflecting object that exists in a forward region of the own vehicle, and a lamp control unit 16 that controls a vehicular lamp 2 to emit light of first illuminance toward a first light-reflecting object for which the size as seen from the own vehicle is a first size, and to emit light of second illuminance lower than the first illuminance toward a second light-reflecting object for which the size as seen from the own vehicle is a second size larger than the first size.
