  • Publication number: 20070092636
    Abstract: Disclosed herein is a method of making a light emitting device comprising an LED and a molded silicon-containing encapsulant. The method includes contacting the LED with a photopolymerizable composition containing a silicon-containing resin having silicon-bonded hydrogen and aliphatic unsaturation and a metal-containing catalyst that may be activated by actinic radiation. Photopolymerization of the photopolymerizable composition is then carried out to form the encapsulant. At some point before polymerization is complete, a mold is used to impart a predetermined shape to the encapsulant.

  • Publication number: 20060290842
    Abstract: A display system has a controlled transmission mirror disposed between the light sources and the display panel. The controlled transmission mirror includes a light-diverting input coupling element facing the light sources, a light-diverting output coupling element facing the display panel and a multilayer reflector between the input and output coupling elements. The controlled transmission mirror laterally spreads the light, making the illumination of the panel more uniform. The controlled transmission mirror may include a transparent substrate between the input and output coupling elements for additional light spreading. The light sources may be positioned within the controlled transmission mirror, rather than behind it. The output coupling element can be insensitive to polarization, so the light passing out of the controlled transmission mirror is unpolarized, or the output coupling element can be polarization sensitive so that the output light is polarized.

  • Publication number: 20060262400
    Abstract: A reflective polarizer and a dichroic polarizer are combined to provide an improved optical polarizer. The dichroic and reflective polarizers are typically in close proximity to each other, and are preferably bonded together to eliminate the air gap between the polarizers. The combination of the two polarizers provides a high reflectivity of one polarization and high transmission for the perpendicular polarization from the reflective polarizer side of the combined polarizer, and high absorption and transmission for light of orthogonal polarization from the dichroic polarizer side. The combination also reduces iridescence as seen in transmission and when viewed in reflection from the dichroic polarizer side. The increased extinction ratio and low reflectivity of the optical polarizer allows use of a lower extinction ratio dichroic polarizer in applications requiring a given extinction ratio and high transmission.

  • Publication number: 20060255486
    Abstract: Optical bodies, for example optical films, are formed with inorganic fibers embedded within a polymer matrix. In some embodiments, the refractive indices of the inorganic fibers and the polymer matrix are matched. There need be no bonding agent between the fibers and the polymer matrix. The inorganic fibers may be glass fibers, ceramic fibers, or glass-ceramic fibers. A structure may be provided on the surface of the optical body, for example to provide optical power to light passing through the optical body. The body may be formed using a continuous process, with a continuous layer of the inorganic fibers being embedded within the matrix which is then solidified.

  • Publication number: 20060232863
    Abstract: A multilayer reflector useable to reflect or transmit light over the visible wavelength range includes optically thick constituent layers. The optical thickness of the constituent layers through the thickness of the reflector defines a layer thickness profile. The layers are arranged so that the thickness profile has a tailored non-uniform distribution, such as a graded distribution or a randomized distribution. The layers desirably have an optical thickness in a range from about one to five or one to ten design wavelengths. The reflector can be a polarizer, reflecting only one normally incident polarization state, or a mirror, reflecting two normally incident orthogonal polarization states.

    Abstract: An article, such as a film, comprising a body portion and a surface portion is provided. The body portion has (i) a first and a second surface, and (ii) first and second in-plane axes that are orthogonal with respect to each other and a third axis that is mutually orthogonal to the first and second in-plane axis in a thickness direction of the body. The surface portion comprises a linear geometric feature disposed on the first surface of the body in a direction substantially parallel to the first in-plane axis of the polymeric body. The article has (i) a first index of refraction (n1) along the first in-plane axis, (ii) a second index of refraction (n2) along the second in-plane axis, and (iii) a third index of refraction (n3) along the third axis, wherein n2 and n3 are substantially the same but substantially different from n1; and wherein the uniaxially oriented polymeric film has a relative birefringence of 0.

  • Publication number: 20060194487
    Abstract: A polarizer is formed with an arrangement of polymer fibers substantially parallel within a polymer matrix. The polymer fibers are formed of at least first and second polymer materials. At least one of the polymer matrix and the first and second polymer materials is birefringent, and provides a birefringent interface with the adjacent material. Light is reflected and/or scattered at the birefringent interfaces with sensitivity to the polarization of the light. In some embodiments, the polymer fibers are formed as composite fibers, having a plurality of scattering polymer fibers disposed within a filler to form the composite fiber. In other embodiments, the polymer fiber is a multilayered polymer fiber. The polymer fibers may be arranged within the polymer matrix as part of a fiber weave.

  • Publication number: 20060193578
    Abstract: An optical element is formed by co-extruding to have an arrangement of polymer scattering fibers within a polymer matrix. The scattering fibers lie substantially parallel to a first axis. The scattering fibers are arranged at positions across the cross-section of the polymer matrix to scatter light transversely incident on the optical element in a direction substantially orthogonal to the first axis. The positions of the scattering fibers across the cross-section of the optical element may be selected so as to form a two-dimensional photonic crystal structure for light transversely incident on the optical element.

  • Publication number: 20060194046
    Abstract: A composite polymer fiber comprises a polymer filler material and a plurality of polymer scattering fibers disposed within the filler material. At least one of the filler material and the scattering fibers is formed of a birefringent material. The refractive indices of the filler material and the scattering fibers can be substantially matched for light incident in a first polarization state on the composite polymer fiber and unmatched for light incident in an orthogonal polarization state. The scattering fibers may be arranged to form a photonic crystal within the composite fiber. The composite fibers may be extruded and may be formed into a yarn, a weave or the like. If the filler material is soluble, it may be washed out of the yarn or weave, and the scattering fibers may then be infiltrated with a resin that is subsequently cured.
