Abstract:
A lamp body control system comprising:a steering angle sensor for detecting a steering angle; a light emitting unit capable of changing a illuminating direction thereof at least laterally; a driving unit for changing the illuminating direction of said light emitting unit; a control unit for controlling said driving unit based on an output from said steering angle sensor; and a straight ahead driving condition determining unit for determining a straight ahead driving condition of a vehicle, wherein, until said straight ahead driving condition determining unit determines that said vehicle is in the straight ahead driving condition after an ignition switch is turned on, said control unit directs the illuminating direction of said light emitting unit to a direction according to a steering direction and a variation in the steering angle in the event that the variation in the steering angle is larger than a predetermined value, whereas in the event that the variation in the steering angle is equal to or smaller than said predetermined value, said control unit returns the illuminating direction toward a direction facing the front of said vehicle at a predetermined returning speed.
