    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 illumination arrangement for a vehicle headlight is formed of a plurality of contiguous elementary cells, each including a light source, defined by an emission surface having a horizontal dimension and a vertical dimension and capable of emitting a luminous flux, and an optical system capable of conveying the luminous flux at a predetermined solid angle about a predetermined direction. The elementary cells are disposed so as to generate overall a predetermined distribution of light emission. The horizontal dimension and the vertical dimension of the emission surface of the light sources are different. The vertical dimension is less than 1 mm and the ratio between the horizontal dimension and the vertical dimension is greater than 2.

    Abstract: A light-emitting device, in particular a backlight device, comprises a transparent substrate (2) having a front surface and a rear surface, in which associated to the rear surface are means for generating an electromagnetic radiation that is able to pass through the substrate and come out of the front surface. According to the invention, the device comprises a layer of porous alumina which operates so as to inhibit propagation of said electromagnetic radiation in the directions parallel to the plane of the substrate, thus improving the efficiency of extraction of light from the substrate and increasing the directionality of the emitted light.

    Abstract: A reflector for a vehicle headlight is described, capable of illuminating the surrounding space according to a predetermined light distribution. The reflector is formed of a plurality of sectors capable of reflecting the light beam emitted by a light source of the headlight and directing it into predetermined regions of said light distribution. The major part of the sectors of the reflector is delimited at least in part by an edge in which the divergence value of the light beam reflected at said edge portions is constant. The sectors delimited by edge portions having lower values of the angle of spread are arranged to direct the light beam reflected thereby into the regions of the light distribution having a higher spatial gradient of illuminance.
