  • Publication number: 20130241435
    Abstract: A lighting device (100) includes a housing (104), a light converter (136), one or more light sources (132), and one or more optical waveguides (160). The housing includes a light exit (124) for outputting a combination of primary light (140) and secondary light (156,158). The light source emits a primary light beam of a primary wavelength. The optical waveguide includes an input end (162) optically coupled to the light source, and an output end (164) facing a housing interior (108) and positioned at an angle to an axial direction through the housing interior. The optical waveguide directs the primary light beam from the light source, through the housing interior and toward a luminescent material of the light converter. The luminescent material emits secondary light of one or more wavelengths different from the primary wavelength in response to excitation by the primary light beam. The light source may be mounted outside the housing interior so as not to obstruct light propagation.

  • Publication number: 20130188389
    Abstract: An artificial lighting system. The artificial lighting system generates electromagnetic radiation at a source location, and outputs the electromagnetic radiation at a target location. The output is in the form of electromagnetic radiation in the visible spectrum and/or photosynthetically active radiation. In some embodiments, the electromagnetic radiation is focused and distributed through one or more lenses to provide increased intensity. For target locations that are physically remote from the source location, optical waveguides and components distribute the electromagnetic radiation. Some embodiments incorporate an automated emitter allowing the output of the artificial lighting system to be moved at the target location. The artificial lighting system seeks to provide high intensity electromagnetic radiation to the target while minimizing the exposure of the target to the heat generated by the light source.

  • Patent number: 8388185
    Abstract: An image display device comprises a light-emitting unit (1), an optical fiber (2) which transmits light emitted from the light-emitting unit, and a plurality of spheres (3) disposed so as to be coupled to the optical fiber (2) by evanescent coupling and having optical transparency. Each of the spheres (3) produces an optical mode in which light entering each sphere from the optical fiber (2) by the evanescent coupling is confined inside, and are so formed that predetermined resonant frequencies of the spheres for producing the optical mode are different from one another, so that an image is displayed by the light emitted from the spheres (3). This provides a simply structured image display device having a high response speed and capable of achieving power saving, a high luminance, a wide view angle, and a high contrast.
