Abstract

A movable shade 26 for shielding a part of light emitted from a light source 22a toward a reflecting surface 24a of a reflector 24 is moved between two positions in a longitudinal direction by a shade driving device 28 according to a vehicle running situation, thereby changing a region in which the reflecting surface of the reflector 24 is to be utilized. More specifically, light emitted toward an outer peripheral region 24a2 of the reflecting surface 24a is shielded to permit only light incidence on an inner peripheral region 24a1 thereof when the movable shade 26 is moved to a forward position, while light emitted toward the inner peripheral region 24a1 of the reflecting surface 24a is shielded to permit only light incidence on the outer peripheral region 24a2 when the movable shade 26 is moved to a rearward position.

Claims6

Dependent claims

A lighting system for a vehicle having a light source and a reflector for forward reflecting light emitted from the light source and constituted to carry out beam irradiation toward a forward road of the vehicle in a predetermined light distribution pattern, the lighting system comprising:

a movable shade constituted to shield a part of light emitted from the light source toward a reflecting surface of the reflector, and a shade driving device for moving the movable shade between two positions in a longitudinal direction,
wherein light emitted toward an outer peripheral region of the reflecting surface is shielded to permit only light incidence on an inner peripheral region of the reflecting surface when the movable shade is moved to a forward position, while light emitted toward the inner peripheral region of the reflecting surface is shielded to permit only light incidence on the outer peripheral region of the reflecting surface when the movable shade is moved to a rearward position.
