    Abstract: An optical element and module for the projection of a light beam, and motor vehicle lamp including a plurality of such modules An optical element for the projection of a light beam comprises a solid body (1) of transparent material in which is formed a cavity (13) able to receive a light source (10), the cavity (13) extending along the principal axis (z) of the transparent body (1) and being delimited by a radially inner surface (3) and a terminal surface (2) of the transparent body (1). The surfaces (2, 3) are able to receive separate respective portions (I, II) of the light flux generated by the source (10). The transparent body (1) further has a radially outer surface (4) which surrounds the radially inner surface (3). The radially outer surface (4) reflects the portion of the light flux (I) coming from the radially inner surface (3) along a direction substantially parallel to the principal axis (z). The transparent body (1) has, on the opposite side, a central surface (6) and an annular surface (5) surrounding the central surface (6), able to receive that portion (II) of the light flux and the reflected portion of the light flux (I) respectively and to transmit these light flux portions (I, II) in directions having predetermined orientations with respect to the principal axis (z). At least one of the surfaces (2, 3, 5, 6) is rotationally asymmetric with respect to the principal axis (z) of the transparent body (1). The surfaces (2, 3, 5, 6) cooperate in such a way as to shape the overall light flux (I, II) emitted by the central and annular surfaces (6, 5) into a light intensity distribution having different divergences in two 25 directions perpendicular to one another and to the principal axis (z).

    Abstract: Multifunctional optical sensor, comprising a matrix of photodetectors of the CCD or CMOS type, having a sensitive area divided into sub-areas, each of which, individually or combined with others, is dedicated to a specific function of monitoring the scene or measuring environmental parameters. The optical sensor comprises a matrix of microlenses, each of which is set to focus the radiation coming from a portion of solid angle on the associated photodetector or cluster of mutually contiguous photodetectors. Each function is associated to a single microlens or to a single subgroup of mutually contiguous microlenses or to multiple, not mutually contiguous microlenses or to multiple, not mutually contiguous subgroups of microlenses. The angular separation between the central directions of the portions of solid angle subtended by adjacent photodetectors or adjacent clusters of photodetectors is not constant within the matrix.

    Abstract: An optical module for projecting a light beam comprises a solid body of transparent material into which a light source is sunk and which is delimited by an annular surface and by a central surface, and a substantially annular reflecting surface arranged around the solid body. The central and annular surfaces are suitable for receiving respective distinct portions of the luminous flux produced by the source. The reflecting surface may have a reflecting coating or may form part of a transparent body, in which case it works by total internal reflection. The reflecting surface reflects a portion of luminous flux refracted by the annular surface and shapes the flux into a predetermined distribution of luminous intensity about the principal axis. The annular surface is designed in a manner such as to reduce the overall thickness of the module by moving the refracted ray away from the principal axis. The central surface shapes the other portion of the luminous flux emitted by the source into a predetermined distribution of luminous intensity about the principal axis. The surfaces cooperate so as to shape the luminous flux as a whole emerging from the source into a distribution of luminous intensity having divergences which may be different in two directions that are perpendicular to one another and to the principal axis.
