<p>PROBLEM TO BE SOLVED: To accurately execute irradiation directional control for a vehicular lighting fixture by referring to the load distribution on a vehicle even if a car height detecting means is mounted only on one axle part out of the front and rear wheels of the vehicle. SOLUTION: In an irradiation directional control device for a vehicular lighting fixture 1 where the irradiating direction of the lighting fixture 6 is changed in response to the attitude of the vehicle in the advancing direction of the vehicle, the control device is provided with a car height detecting means 2 for detecting the change in height for an axle part for the front or rear wheels of the vehicle, and with a driving means 5 for directing the irradiation beam of the lighting fixture to the intended direction. A load distribution detecting means 3 is also provided, which is to detect the load distribution of the vehicle accompanied by change of occupants in number or loading cargos, the change in loading cargo for the vehicle accompanied by the change in a condition of getting aboard the vehicle or a loading condition, is grasped so as to allow a correction signal for keeping the irradiating direction of the lighting fixture 6 to the specified reference direction, to be generated by an irradiation control means 4 in response to the detected signal of the car height detecting means 4, and the signal is thereby forwarded to the driving means 5 for the lighting fixture 6.</p> |
