<p>The headlamp comprises a body provided with an ellipsoidal reflector (1) and a light source (2) disposed in the vicinity of the focus (F) of this reflector situated towards the base, this light source having its centre or its axis (2a) raised by a distance (d) in relation to the optical axis (A) of the reflector, this headlamp being especially intended for passing (dipped headlamp) and comprising a reflecting hemispherical dish (3) turning its concave surface upwards and the centre of which coincides with the focus (F) of the reflector close to the light source. The rim (6) of the dish (3) is cut in such a way that the dipped light rays (7) are flush with this edge and reach the reflector substantially at the same level throughout, in a plane (H), especially horizontal, located below a parallel plane passing through the optical axis (A) of the headlamp at a distance substantially equal to d. <IMAGE></p> |
