    摘要： 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 directions perpendicular to one another and to the principal axis (z).

    摘要： An optical system for image projection, particularly for projection devices of the “head-mounted” type, includes a display, an optical system for focusing an image formed by the display, and a light guide having an extended body, with two opposite, longitudinal, plane and parallel faces, and opposite ends which define first reflecting surface for coupling into the light guide and second reflecting surface for extracting the image from the light guide. Each light ray which propagates through the light guide undergoes at least three internal total reflections on the parallel plane faces of the light guide. At least a surface of the focusing optical system is a portion of a surface free of rotational symmetry axes. Moreover, the two reflecting surfaces of the light guide are portions of surfaces free of rotational symmetry axes. Finally, the inlet pupil of the light guide coincides with the outlet pupil of the focusing system.

    摘要： The lighting device comprises a light source and an associated hollow reflector of transparent material having an internal surface and an external surface which are close to and far away from the source respectively. The inner surface of the reflector has in cross section at least one transverse plane passing through the source a discontinuous profile forming a plurality of adjacent steps each of which has a first face through which rays originating from the source can pass and a second face essentially parallel to the rays originating from the source. The outer surface of the reflector has a profile comprising one or more arcs of curves. The reflector is constructed and positioned in such a way that in the said transverse plane most of the rays emitted by the source are reflected through the first face of the steps on its inner surface and strike its outer surface undergoing total internal reflection and after passing back through the reflector emerge from it through the second faces of the steps on its inner surface undergoing a second refraction.

    摘要： 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 center 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 center 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.
