    摘要： An optical sheet (25) for spreading light has a substantially smooth surface (27), and a structured surface (28) comprising an array of prisms (30, 31). A beam of light that is to be spread is directed through the film from the smooth surface. Some of the prisms (termed “refraction prisms”) deviate normally-incident light only by refraction at a prism facet as the light leaves the film while others (termed “reflection prisms”) deviates normally-incident light by total internal reflection within the prism before the light leaves the film. There are a plurality of reflection prisms (30) selected to deviate normally-incident light through different angles and a plurality of refraction prisms (31) selected to deviate the normally-incident light through different angles, and they are arranged, preferably in a non-ordered manner, so that successive reflection prisms are separated by at least one refraction prism. In alternative embodiments, the structured surface comprises a non-ordered arrangement of a plurality of reflection prisms selected to deviate normally-incident light through different angles, or a non-ordered arrangement of a plurality of refraction prisms selected to deviate normally-incident light through different angles.

    摘要： The invention is directed to an illumination apparatus that includes a light guide within a recessed housing. A light source, such as a light emitting diode can be used to provide light to the light guide. The light is transmitted through the light guide via total internal reflection (TIR), and can be emitted in a controlled manner to ensure that a desired angular distribution of light is achieved without substantially illuminating interior side walls of the recessed housing. In this manner, efficient lighting can be provided. In one embodiment, the invention is can be implemented within a cosmetic compact that includes a mirror. The compact may incorporate aspects of the invention by implementing a light guide within a ring-shaped recess of the compact to provide facial lighting to a user.

    摘要： Bistable electrocapillary devices useful as optical devices, which can be arranged in arrays to provide optical displays, use mercury/electrolyte interfaces which may be located in reservoirs in the form of narrow parallel gaps between an insulating sheet and glass plates. The gaps are connected by a capillary which extends through the sheet. A variable radius circular mirror is formed by the surface of the mercury where it contacts the glass sheets. A potential is applied briefly (as a pulse) across the interface to switch the mercury between two stable states. The diameter of the mirror is thereby also switched between two stable values. Light reflected from the mirror is modulated by variations in the mirror diameter. A panel display utilizes an arrangement of devices forming an array of mirrors which modulate light reflected therefrom to form an image in accordance with switching signals applied to the devices of the array.

    摘要： A light exposure system is used to expose an alignment layer formed of anistropically absorbing molecules so as to allow alignment of subsequently applied liquid crystal polymer (LCP) molecules. The light incident on the alignment layer is polarized. When a single polarizer is used, the azimuthal polarization direction varies across the substrate carrying the alignment layer. Various approaches to reducing the azimuthal polarization variation may be adopted, including the introduction of various types of polarization rotation reduction element and in selecting an appropriate tilt angle for the light source. Furthermore, a reflective structure may be inserted between the light source and the alignment layer. Use of the reflective structure increases the total amount of light incident on the alignment layer.

    摘要： A luminaire for distributing light from a light source (7). The luminaire includes one or more reflectors (2, 3), placed symmetrically about the lamp (7) to reflect the light output from the lamp (7). One or more light spreading devices (4, 5) are provided around the reflectors (2, 3) to receive the light reflected by the reflectors (2, 3). Such a luminaire provides for uniform distribution of light while minimizing glare from the light fitting.

    摘要： An illumination system comprises a light source optically coupled with an optical fiber. The optical fiber includes a light emitting region extending along a portion of its length. The light emitting region includes a plurality of optical elements disposed about a first longitudinal axis extending along the surface of the optical fiber and a plurality of optical elements disposed about a second longitudinal axis extending along the surface of the fiber. The second longitudinal axis is displaced from the first longitudinal axis. In use, light from the light source is injected into the optical fiber and propagates along the fiber according to Snell's law. A portion of the light propagating through the fiber becomes is reflected from the optical elements and is extracted from the fiber.
