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.

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： 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.

摘要： 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).
