<p>PURPOSE:To contrive the improvement of driving visibility enabling a device to correspond to every road condition by preparing two or more expressions as the arithmetic expression of an irradiation direction, corresponding to a steering angle, in a control part, which calculates the irradiation direction of a lamp corresponding to the steering angle of a handle, and selectably applying these expressions. CONSTITUTION:In a control device 10, a signal from a sensor part 1, mounted to a steering handle, is amplified and shaped in a buffer amplifier 2 and input to a control part 3 here calculating a deflection angle of right and left lamps 5L, 5R corresponding to an output of the sensor part 1. Being based on this arithmetic result, a mechanism part 6, provided in the lamps 5L, 5R, turns an auxiliary reflecting mirror 7 by a motor M, and the objective direction is irradiated. Here in the control part 3, two or more arithmetic expressions are built, and whichever arithmetic expression to be applied can be arbitrarily selected by a driver operating a control part 4 in accordance with a change of conditions of urban road running time, suburban road running time, curved road running time, etc.</p> |
