Headlamp optical module for a motor vehicle comprising, disposed along an optical axis: an elliptical-type reflector with at least one light source placed in the vicinity of a first focal point of the reflector; a converging lens placed in front of the reflector and admitting a focal point located in the vicinity of the second focal point of the reflector; and a light recovery means suitable for collecting a portion of the flux from the source and for sending it forward. An ellipsoid-type reflector is provided at the front, in the upper portion of the module, this reflector focusing a portion of the rays issuing from the source in the vicinity of a second focal point located at the front, lower than the focal point of the lens, and the light recovery means has an input face, in proximity to which is located the second focal point of the ellipsoid-type reflector.
