  • Optical element and module for the projection of a light beam, and motor vehicle lamp including a plurality of such modules
    Patent number: 7651246
    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).

  • Light device, particularly a light panel for road signs or information to the public, or a motor-vehicle light
    Patent number: 7182482
    Abstract: A light device, for example in the form of a light panel for road signals or in the form of a motor-vehicle light, comprises an array of light sources, such as LEDs or the like. Associated to each light source is an optical system consisting of a refractive lens of a plane-convex type having a plane face facing the light source, in which a diffuser of a refractive or diffractive micro-optical type is incorporated.
