Abstract (en)
[origin: WO2016066929A1] 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).
