Optical assembly comprising reflectors provided with discontinuities

Optical module, particularly for a motor vehicle, comprising:

• a light source emitting light rays;
• a projection optic having an optical axis and an object focal point FL;
• a reflector comprising two cavities each comprising a reflection surface for reflecting the light rays originating from the light source towards the projection optic;
• a cut-off device designed to mask part of the light beam, the cut-off device comprising a transverse cut-off edge, the cut-off edge being arranged at the object focal point FL of the projection optic;
• each of the cavities being arranged on either side of an axial plane comprising the optical axis, the reflection surface of each cavity being divided into a lateral part and a central part of the cavity, the central part of each cavity being arranged along the axial plane, the lateral part of each cavity being transversely located at a distance from the axial plane, each reflection surface having a single object focal point that coincides with the light source,
• wherein the lateral part of each cavity has a single image focal point coinciding or substantially coinciding with the object focal point of the projection optic, and
• the central part of each cavity comprises a plurality of image focal points distinct from the object focal point of the projection optic,
• the cavities being designed so that the light rays reflected by the central parts of the reflector pass through a central part of the projection optic, the central part of the projection optic extending in the vicinity of an intersection between the projection optic and the plane,
• the light rays reflected by the lateral parts of the reflector passing through two lateral parts of the projection optic transversely located on either side of the central part of the projection optic.
