The inner focal point (23) of the vertical ellipse (22) of the reflector (10) lies in the incandescent coil (12), and the outer focal point (24) in immediate proximity to the plane of the light exit aperture. The focal length of the horizontal ellipse (32) is shorter than that of the vertical ellipse (22), and the focal point interval of the horizontal ellipse (32) greater than that of the vertical ellipse (22), by a factor of 2:1. An upper shutter (58) is displaced in the direction of the x-axis (11) relative to the shutter (53) and is not curved. A filter (60) is arranged in front of the objective (15), and both consist of pressed glass with a surface constitution producing the blurring of the light-dark limit. With the headlamp, the range and the lateral scattering of the dipped light beam are increased and the overall length of the headlamp is reduced. <IMAGE> |
