<p>PURPOSE:To prevent dazzling from being given to a car running on the opposite direction by variably setting a lamp means in its irradiating direction to a predetermined deflecting angle position in a running direction left side in the time of straight advance steering, in case of the lamp means variably setting its irradiating direction being associated with handle steering. CONSTITUTION:A control signal generating circuit 30 is constituted being provided with an UP/DOWN switching circuit 5 feeding a processing signal in accordance with handle steering, UP/DOWN counter 6, digital comparators 8 to 10 and a comparator 16 or the like. While a servomotor control circuit 40 is constituted of a position displacement detecting circuit 41 inputting a control signal from said circuit 30, motor drive time arithmetic circuit 42, direction of rotation discriminating circuit 43, AND gate circuit 44, etc. When a steering angle is in a degree of zero, a headlamp fixes its irradiating direction to a predetermined deflecting angle position in a vehicle left side, and an electric motor 46 is controlled so as to linearly variably set the irradiating direction to right and left being associated with steering from a straight advance steering position with said deflecting angle position serving as the start point.</p> |
