Claim:
1. A lighting unit comprising: a reflector; and emission devices for emitting a luminous flux in the direction of said reflector, said reflector comprising optical deflection devices for optical deflection of said flux toward an outlet of said lighting unit, said reflector including a support wall disposed across said optical deflection devices so as to be disposed between said optical deflection devices and said emission devices, said support wall including a masking portion that is disposed facing said emission devices and an edge of which is cut out so as to form a mask integral with said support wall adapted to allow to pass only a portion of the rays emitted by said emission devices, said masking portion being integrally formed in said support wall and having a cut-off edge that is adapted to block rays that are oriented or directed outward said optical deflection devices while permitting light rays directed toward said optical deflection devices to pass thereto; wherein said support wall is disposed across said optical deflection devices so as to leave a passage between said optical deflection devices and a rear edge of said support wall, wherein said edge of said masking portion extends at these transverse ends in continuity with said rear edge of said support wall; wherein said reflector includes a frame for supporting said optical deflection devices that includes at least one wall delimiting said optical deflection devices, and in that said edge of said masking portion is cut away to correspond to a given position of said at least one wall delimiting said optical deflection devices.
