Optical axis adjustment mechanism for an automobile headlight

摘要

An optical axis angle adjustment mechanism relative to a horizontal line passing through a light source for an automobile headlight comprising: a speed detector for detecting the driving speed of the automobile; an automobile body angle detector for detecting the automobile body angle or inclination, and for detecting its magnitude relative to a horizontal line in a front-back direction; and a driving unit for performing the optical axis direction adjustment of the automobile headlight based upon the results from the speed detector and the automobile body angle detector. <IMAGE>
