  • Publication number: 20150070900
    Abstract: The present disclosure describes a compact spotlight that can change the area which it illuminates. The spotlight incorporates a wide angle light source, a catadioptric lens, and a bearing system for moving the catadioptric lens, the light source, or both. Movement of the light source relative to the catadioptric lens along the optical axis can change the beam diameter of the spotlight, while providing an acceptable illumination pattern.

  • Publication number: 20150069916
    Abstract: The present disclosure provides a system and method for controlling spot lights, such as theater or display lights, which incorporates a handheld remote control that uses intuitive motions for selecting, positioning, dimming and other lighting setup functions. The present disclosure describes a spotlight control device, a lighting system including the spotlight control device, and a method for spotlight control. The spotlight control device incorporates a first light source that emits a first control beam that activates a desired spotlight. The activated spotlight can provide feedback to indicate that it has been activated. A second light source from the control device emits a second control beam that is used to direct the activated spotlight to an illumination region.

  • Publication number: 20150060551
    Abstract: Retroreflective articles comprise a substrate and a bar code provided on the substrate. The bar code comprises at least one human-readable information which provides framing information and a machine-readable information which provides variable information. The human-readable information is visible under a first condition and invisible under a second condition, and the machine-readable information is invisible under the first condition and visible under the second condition.

  • Publication number: 20140340927
    Abstract: A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.

  • Patent number: 8798421
    Abstract: Polymer fibers are formed with concentric alternating layers of different polymer materials. The layers pairs have cross-sectional thicknesses selected for reflecting light at a selected visible wavelength. A cross-sectional dimension of the core is at least ten times an average of the selected thicknesses of the alternating layers. Some articles formed by the fibers are formed by attaching one fiber to another: the color of the fibers at the point of attachment is different from the colors of the fibers elsewhere. The fibers may be deformed to change its color properties by elongating the cross-section of the polymer fiber along a first cross-sectional axis. In some embodiments, the fibers are polarization sensitive.

  • Patent number: 8530118
    Abstract: Methods of fabricating optical elements that are encapsulated in monolithic matrices. The present invention is based, at least in one aspect, upon the concept of using multiphoton, multi-step photocuring to fabricate encapsulated optical element(s) within a body of a photopolymerizable composition. Imagewise, multiphoton polymerization techniques are used to form the optical element. The body surrounding the optical element is also photohardened by blanket irradiation and/or thermal curing to help form an encapsulating structure. In addition, the composition also incorporates one or more other, non-diffusing binder components that may be thermosetting or thermoplastic. The end result is an encapsulated structure with good hardness, durability, dimensional stability, resilience, and toughness.
