    Abstract: A system for projecting a virtual image within an observer's field of view comprises a support element, a transparent element mounted on the support element and suitable for being placed in front of the observer's eyes, the transparent element comprising a first face and a second face, an image display device suitable for forming an additional image, and a projection and focusing device for projecting the additional image in a manner such as to present it superimposed on the image of the outside world. The display device comprise light-emitting devices disposed on one of the faces of the transparent element, and the projection and focusing device comprise optical elements associated with respective emitting devices and arranged on the other face. Each of the optical elements creates a virtual image of the emitting device associated therewith. The virtual images of the emitting devices together form the additional image.

    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 light concentrator is described, for a device for the conversion of solar radiation into electrical, thermal or chemical energy, capable of conveying the radiation towards a surface of the conversion device. The concentrator comprises at least one portion of Fresnel lens of rotational symmetry, one face of which has a plurality of crests disposed concentrically about a centre so as to form a segmented transverse profile of the portion of Fresnel lens. The profile is formed in such a manner that the focal distance of the Fresnel lens is variable in dependence on the radial distance from the centre of the lens. The variation of the focal distance is determined such that, when the Fresnel lens is illuminated by polychromatic radiation, the superposition of the distributions of irradiance, produced by the lens at the individual wavelengths constituting the spectrum of the incident radiation, generates a substantially uniform distribution of polychromatic irradiance on the conversion device.

    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.
