The light control layer comprises an enhanced specular reflector (ESR, 16a) film in optical contact to at least one layer of a transparent or translucent material (16B, 16C). The light control layer transmits light from the light source more readily than the ESR film standing on its own. In some embodiments the display may provide enhanced contrast and peak luminance.

  • Patent number: 9297517
    Abstract: A light source is combined with an optic and a reflector. Light incident onto to the reflector is reflected with a single reflection. The reflector occupies a portion of a solid angle around the light source to the exclusion of the optic at least with respect to any optical function. The reflector directly receives a second portion of light. The optic occupies substantially all of the remaining portion of the predetermined solid angle to directly receive a first portion of light from the light source. A reflected beam from the reflector is reflected into a predetermined reflection pattern. The inner and/or outer surface of the optic is shaped to refract or direct light which is directly transmitted into the optic from the light source from a first portion of light and/or reflected into the optic from the reflector from the reflected beam into a predetermined beam.

  • Publication number: 20140340899
    Abstract: An integrated solid-state lamp comprised of thermally conducting materials such as alumina ceramic or graphite filled polymers may simultaneously perform optical operations on the light emerging from solid-state emitters to enable the creation of a lamp which produces light in both direct and indirect light zones with a near-field uniformity more comparable to that produced by a vertical filament incandescent lamp. The light chamber structures may incorporate optical light path modifiers which push light into additional lighting zones for proximately omnidirectional light. Diffuser structures may incorporate hole patterns to improve thermal flow and light recycling efficiency. The distribution produced fully encompasses 0-180 deg. Light produced by the lamp chambers or atrium serve in like manner to the atrial chambers of the heart to produce light uniformly in all directions for general illumination at high efficiency.
