Document Type and Number:
Japanese Patent JP6458333
Kind Code:
B2
Abstract:
A vehicle lighting fixture (500A) can include a plurality of optical deflectors (201) while the miniaturization can be achieved as well as the parts number, which may become a cause for cost increase, can be decreased. The vehicle lighting fixture (500A) can be configured to form a predetermined light distribution pattern, and can include a plurality of light sources (12); a plurality of optical deflectors (201) provided to correspond to the plurality of light sources (12), the optical deflector (201) configured to include a mirror part (202) that can scan with light from a corresponding one of the light sources (12); a screen member (18) configured to form a luminance distribution assigned to each of the optical deflectors (201) with the scanning light by the mirror part (202) of the optical deflector (201); an optical system (20) configured to project the luminance distributions formed on the screen member (18) to thereby form the predetermined light distribution pattern; a changing unit (504) configured to change the luminance distribution assigned to each of the optical deflectors (201); and a control unit (504) configured to control the plurality of light sources (12) and the plurality of optical deflectors (201) so that the plurality of optical deflectors (201) each can form the respective luminance distributions assigned to the respective optical deflectors (201) on the screen member (18). Herein, the changing unit (504) can change the respective luminance distributions assigned to the respective optical deflectors (201) at a prescribed timing.
