Abstract
In this light distribution control device in order to provide a vehicular lighting fixture for an Adaptive Frontlighting System (AFS) in which a lot of light distribution patterns can be set without making the entire lighting fixture larger, beams which link said movable substrates to said inner frames and beams which link said inner frames to said outer frame are mutually orthogonal, and a light distribution pattern is set by deforming under torsion the beams which link said movable substrates to said inner frames and the beams which link said inner frames to said outer frame, and swinging each of said movable substrates with respect to said outer frame in the biaxial directions independently.
