ABSTRACT:
A lighting module for a motor vehicle headlight for giving a cutoff beam, having an optical axis and comprising at least one light source (S), a reflector (R, Ra, Ra1, Ra2) of the complex surface type, and a cylindrical lens (L, La) with substantially vertical generatrices placed between the two foci (F1, F2) of the arc of an ellipse. The light source consists of at least one light emitting diode disposed so that its light beam has a mean direction (Δ, Δa) substantially orthogonal to the geometric axis of the reflector (R, Ra, Ra1, Ra2), which is situated relative to the plane of the rear face of the light emitting diode, on the emitted beam side, and in calculating its surface area account is taken of the protective lens of the light emitting diode.
