    摘要: A thin, flexible film made of a transparent polymeric material including a structured surface and an opposite smooth surface, wherein light striking either surface, within certain angular ranges, is totally internally reflected. The structured surface includes a linear array of miniature substantially right angled isosceles prisms arranged side-by-side to form a plurality of peaks and grooves. In addition, the perpendicular sides of the prims make an angle of approximately 45° with the smooth surface, and when the film is curled the smooth surface lies in a smooth continuous arcuate curve without materially affecting the performance of the film. Because of the film's flexibility and its ability to totally internally reflect light, it may be utilized in a variety of ways, for example, as a collector of solar energy or as a light conduit. The performance of the film may be manipulated to permit controlled light leakage.

    摘要: A backlight display includes a case having an optical window through which displayed information may be viewed. In addition it includes an electroluminescent panel for providing the backlight. It further includes a structured surface material between the electroluminescent panel and the optical window. The structured surface material has the property of reflecting light entering it while making an angle in a first predetermined group of angles with the axis of the display back to the electroluminescent panel. It further has the property of refracting light entering it while making an angle in a second predetermined group of angles to the axis of the display such that a majority of the light in the second group will exit in an output wedge that is smaller than the input wedge.

    摘要: In the present invention a wide angle safety lens has two major surfaces, each of which is a structured surface. The first major surface has a plurality of parallel linear prisms forming a Fresnel lens that acts like a cylindrical lens having a first negative focal length. The second major surface has a plurality of parallel linear prisms running perpendicular to the prisms of the first major surface and forming a Fresnel lens that acts like a cylindrical lens having a second negative focal length.

    摘要: A hollow, tubular light conduit including a wall of a transparent polymeric material, and the wall having a structured surface and an opposite, smooth, glossy surface, and at least a portion of the cross-section of the wall lying in a smooth arcuate curve, wherein light striking the inner surface, within an acceptable angular range, is contained by total internal reflection. The structured surface includes a linear array of substantially right angled isosceles prisms arranged side-by-side to form grooves. In addition, the perpendicular sides of the prisms make an angle of approximately 45.degree. with the tangent to the smooth surface. Because of the flexibility of the light conduit and its ability to totally internally reflect light, a manipulated light conduit may be utilized in a variety of ways, for example, as a light fixture whereby some of the light directed into the light conduit is emitted from the light conduit for illumination or for use as a secondary light source. A suitable light source may include artificial or solar energy. However, when the light fixture operates as a warning light it is preferred that a strobe light be used.
