The projector (1) comprises a light source (S), a movement means (20), a moving optical element (4) driven by the movement means (20) to cut and/or reflect a light beam emitted by the source (S), a radiator (30) thermally linked to the movement means (20), and a reflector (12), the light beam being reflected by the reflector (12) before being cut and/or reflected by the moving optical element (4), the reflector (12) having the shape of a portion of a semi-ellipsoid, the source (S) being positioned on the axis of symmetry (X) of the ellipsoid, the radiator (30) being positioned below the plane of symmetry of said ellipsoid, the radiator (30) being situated at least partially inside said ellipsoid between a base (13) of the reflector (12) and the moving optical element (4), and being positioned at least partially within a volume (V) defined by the cylindrical extension, along an optical axis of an optical lens (3), of a peripheral contour of said lens (3) to a transverse plane passing through a base (13) of the reflector (12).

The invention relates to a multi-module motor vehicle headlight comprising moving mirrors actuated by a single motor. The headlight (11) is of the multi-module type and each module (11 a, 11b) constituting said headlight (11) comprises at least one light source and at least one moving member for intercepting the beam (4a, 4b), capable, according to the position thereof, of intercepting or allowing the passage of a part of the light beam coming from the source, the intercepting members (4a, 4b) of at least two modules being actuated by a common movement means, the reflecting surfaces of the two modules being flat mirrors (4a, 4b), said flat mirrors (4a, 4b) being mounted on a common axis (5) and being rotatable around said common axis (5) which is orientated perpendicular to an optical axis.

The invention concerns a cutoff mechanism (5) of an optical module comprising a cutoff bar (10), a motor (30) driving the cutoff bar (10) between at least first and second positions via a transmission shaft (38) of the motor (30) and a driving means for driving the cutoff bar (10) linked to the transmission shaft (38), a return means (15) that tends to return the cutoff bar (10) to the first position of same, characterised by the fact that the driving means comprises a device (81) for decoupling the movement of the transmission shaft (38) relative to that of the cutoff bar (10) when the cutoff bar (10) reaches the first position. The invention also concerns an optical module comprising such a cutoff mechanism (5).
