Abstract:
1. A lighting module for a motor vehicle headlight for giving a cutoff beam, or a low beam, said lighting module having an optical axis and comprising: at least one light source; a reflector of the complex surface type, said at least one light source being disposed substantially at a focus situated on said optical axis, and a cross section of said reflector through a horizontal plane being substantially in an arc of an ellipse having a first focus substantially at the focus where said at least one light source is situated, and a second focus situated in front on said optical axis of said lighting module, said reflector producing towards the front a cutoff beam; and a cylindrical lens with substantially vertical generatrices; said cylindrical lens having at least a portion that is divergent wherein said at least one light source comprises at least one light emitting diode disposed so that its light beam has a mean direction substantially orthogonal to a geometric axis of said reflector; said reflector is situated, relative to a plane of a rear face of said at least one light emitting diode, on the emitted beam side, and in calculating its surface area account is taken of the protective optic part of said at least one light emitting diode; wherein a return mirror is disposed generally opposite said reflector for receiving said light beam from said reflector and redirecting said light beam through said cylindrical lens.
