Abstract:
A headlamp for vehicular use including a rotatable shade composed of a right shade and a left shade and which constitutes a clear-cut line vertically moving adjusting device for vertically moving and adjusting a clear-cut line of a low beam produced by the headlamp, a curved road detecting device for detecting a condition of a curved road in front of the vehicle, and a main optical axis lateral direction tilting adjusting device. The rotatable shade is rotated by a predetermined amount in accordance with the information of a curved road detected by the steering sensor so that the clear-cut line is vertically moved and adjusted. Further, the reflector (and the bulb mounted thereon) is laterally slid by a predetermined amount so that the light distribution pattern and the "hot zone" are laterally moved and adjusted. Accordingly, the visibility, especially the visibility on the steering side, is improved when the vehicle travels on a curved road at either low or high speed.
