  • Patent number: 9857520
    Abstract: A lighting assembly includes a light guide having opposed major surfaces between which light propagates by total internal reflection and a light input edge. The light assembly also includes a light engine. The light engine has a heat conductive armature having a receptacle for a portion of the light guide that includes the light input edge and a light source retained by and thermally coupled to the armature. The armature functions as a heat sink for dissipating heat generated by the light source. The light guide is mechanically retained in the receptacle, and the light guide and the armature cooperate to align the light input edge with the light source for inputting light from the light source into the light guide through the light input edge.

  • Patent number: 9778410
    Abstract: A lighting assembly includes a light guide to propagate light by total internal reflection and having a light output region on a major surface thereof. The lighting assembly also includes an optical adjuster having a major surface juxtaposed with and conforming to the light guide's major surface. The optical adjuster has a first region and a second region, the first region having a light modifying characteristic. The optical adjuster and light output region are variably positionable relative to one another to selectively apportion light emitted from the light output region between the first region and the second region. In this way, light apportioned to the first region is modified by the light modifying characteristic so that light output from the lighting assembly is modified based on relative positioning of the optical adjuster and the light guide.

  • Publication number: 20170254946
    Abstract: An article of manufacture includes first and second micro-features of well-defined shape. In some embodiments, the article of manufacture is a light guide or redirecting film and the second micro-features are micro-optical elements configured to disrupt a specular optical path that includes the second micro-optical element. In other embodiments, the article of manufacture is a patterning tool for use in making an optical substrate. Embodiments of the optical substrate are formed by injection molding or embossing using the patterning tool.

  • Patent number: 9707641
    Abstract: Optical elements with small increments in average density are formed in a substrate by laser micromachining using a variable aperture and a pattern mask set of pattern masks each having of shape-defining elements whose density differs among the pattern masks in first density increments. A laser light beam passes through a combined mask formed by the variable aperture and one pattern mask selected from the pattern mask set. The variable aperture controls beam size and the pattern mask spatially modulates its intensity. A focusing element focuses light from the combined mask on a small averaging region of the substrate. Different combinations of the size of the aperture mask and the selected pattern mask are used in combination at respective averaging regions of the substrate. The resulting average densities of the optical elements vary among the averaging regions in increments that are small compared to the first density increments.

  • Patent number: 9551465
    Abstract: An LED lamp or LED lighting assembly includes a light guide having opposed major surfaces configured to propagate light by total internal reflection and a light input edge extending between the major surfaces. A light source is adjacent to the light input edge and is configured to edge light the light guide. In some embodiments, the light source is moveable relative to the light input edge, and the spectrum of the light output from the light guide may be adjusted by movement of the light source relative to the light input edge.

  • Patent number: 9477029
    Abstract: A lighting assembly includes a light guide having opposed major surfaces between which light propagates by total internal reflection, a light input edge, and two light output regions of different optical characteristics and at least one of which is associated with a corresponding one of the major surfaces. The lighting assembly also includes a light source located adjacent the light input edge. The light source and the light guide variably positionable relative to one another to vary a location on the light input edge at which the light is input to the light guide such that the light is emitted from the light guide selectively apportioned between the light output regions so that a characteristic of the light output from the lighting assembly is modified based on the optical characteristics associated with the light output regions and the relative positioning of the light source and the light guide.
