Abstract
A motor vehicle headlamp comprising in combination an optical system for recovering flux having a rectilinear focal segment and an optical system for rectifying images having a focal segment coinciding with the former and able to produce a beam of rays of controlled directivity passing through a narrow light window, while preserving a high luminous efficiency. The flux recovery system is constituted by an elliptical paraboloid, an hyperbolic paraboloid or their optical equivalents. By using various combinations of optical elements, it is possible to arrange the flux recovery system both in the axis of the rays leaving the headlamp, as well as on the side of the body work or on the lower part of the latter.
