1. A vehicle lighting system for illuminating ahead of a vehicle comprising:
- a plurality of light sources each adapted to illuminate a different illumination area so as to form a light distribution pattern as a whole; and
a control unit for controlling the light distribution pattern by independently changing an orientation of each of the plurality of light sources,wherein the control unit determines a traffic scene in which the vehicle is running and independently changes the orientation of each of the plurality of light sources so as to form a target light distribution pattern set in advance for the traffic scene.

Abstract
A vehicle lighting system for illuminating ahead of a vehicle is provided with a plurality of light sources each adapted to illuminate a different illumination area to thereby form a predetermined light distribution pattern as a whole and a control unit for determining a traffic scene in which the vehicle is running and independently changing at least either an orientations or the light quantities of the plurality of light sources so as to form a target light distribution pattern which has been set in advance for the traffic scene.

10. A vehicle lighting system for illuminating ahead of a vehicle comprising:
-
a plurality of light sources each adapted to illuminate a different illumination area so as to form a light distribution pattern as a whole; a control unit for controlling the light distribution pattern by independently changing an orientation of each of the plurality of light sources; and a camera for taking a photo ahead of the vehicle, wherein the control unit determines the brightness on the road on which the vehicle is traveling ahead from an image obtained by the camera, so that a shoulder of the road is then illuminated by at least part of the plurality of light sources, in the event that the control unit determines that the brightness on the road is at a predetermined value or greater. - View Dependent Claims (11, 12)
