The headlamp has a reflector (10), the vertical and horizontal meridian sections (11, 12) of which are higher-order intersection curves, and a diaphragm (17) forming the rough light beam. The objective is composed of a ground spherical dispersing lens (18) and of an aspherical collecting lens (19), the aspherical surface (23) of which is already completed during the pressing of the lens and does not require any further grinding process. <IMAGE> |
