    摘要: A monolithic element has a substrate body and at least one macro-optical characteristic integral in a first portion of the optical element. A plurality of surface micro-structures are integral in a portion of the optical element. The micro-structures are designed to homogenize light passing through the optical element to produce a predetermined pattern of smoothly varying, non-discontinuous light exiting the optical element. The light exiting the optical element is therefore altered according to both the macro-optical characteristic of the optical element as well as the homogenizing characteristics of the micro-structures.

    摘要: A vehicle light assembly includes a lens cover from which light emanates. A light shaping surface microstructure is carried in a portion of the light assembly. The microstructure can be incorporated into many different surfaces of the light assembly such as a surface of the lens cover, a surface of a macro-optical structure on the lens cover, or on a reflective surface of the assembly. The microstructure homogenizes and directs light emanating from the light assembly via reflection or transmission to provide a smooth, continuous pattern of light having a predetermined distribution shape or envelope and a predetermined directionality.

    摘要: A device has a carrier and an optical element supported by the carrier. The optical element has a macro-optical characteristic and at least one surface. A light shaping surface microstructure is integral on the surface of the optical element. The microstructure homogenizes, shapes and controls directionality of light emanating from the surface of the optical element to produce a smooth, consistent and continuous pattern of light in a predetermined distribution shape and direction. The optical element can either transmit or reflect light incident on a portion of the device and the optical element.

    摘要: A viewing surface in the form of a passive liquid crystal display or front projection viewing screen includes a substrate layer of material having a front side and a back side. A light shaping micro-sculpted surface structure is provided on one side of the substrate layer wherein the microstructure controls the directionality, gain, homogeneity and shape distribution of the light propagated by the screen or display. A reflective layer is deposited on the opposite back side of the substrate layer and reflects light incident upon the substrate layer back through the substrate layer toward a viewing screen surface. This type of construction can be used directly as a viewing screen or can be utilized behind a display such as a liquid crystal display in order to significantly enhance the brightness of such a display or screen. The microstructure can be integral on either the front side of the substrate layer or beneath the reflective layer on the back side of the layer.

    摘要: An apparatus for projecting light on to a predetermined area includes a light source and a transparent element disposed adjacent the light source where in the transparent element is made from a sol-gel type glass, quartz, or other optical material. A plurality of surface micro-structures integral in a surface of the transparent element are provided which both homogenize and control directionality of light passing form the light source through the transparent element. These micro-structures produce a predetermined pattern of highly transmissive, smoothly varying, non-discontinuous light in a predetermined direction which is suitable for any number of applications wherein a sol-gel material transparent element including the diffuser surface structures are particularly well suited.
