Patent number: 11703631Abstract: A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.Type: GrantFiled: November 2, 2020Date of Patent: July 18, 2023Assignee: Quarkstar LLCInventors: Wilson Dau, Robert C.

Patent number: 10417956Abstract: Pixel locations in an addressable display are defined by metal landings on a top surface of a flexible substrate, such as by depositing a metal film and etching the film. The substrate surface may be hydrophobic so that the hydrophobic surface is exposed between the metal landings. The substrate has conductive vias that connect the metal landings to traces on a bottom surface of the substrate for connection to addressing circuitry. LED ink is then blanket-printed over the top surface and cured to electrically connect bottom electrodes of the LEDs to the metal landings. LEDs that fall between the landings are ineffective. A dielectric layer is blanket-printed which exposes the top electrodes, and a transparent conductor layer is blanket-printed over the LEDs to connect all LEDs associated with an individual pixel location in parallel. Accordingly, all printed steps can be performed without any alignment.Type: GrantFiled: December 13, 2018Date of Patent: September 17, 2019Assignee: NTHDEGREE TECHNOLOGIES WORLDWIDE INC.Inventor: Brian D.

Patent number: 9368549Abstract: Over a flexible substrate are formed column lines for a display. Over the substrate and column lines are formed a reflective hydrophobic mesh defining pixels. Over the mesh and column lines is printed an LED ink containing microscopic LED dies. The LED ink de-wets from the mesh. The ink is then cured to electrically connect the bottom electrodes of the LEDs to the column lines within the openings (cells) of the mesh. A dielectric then encapsulates the LEDs while exposing the top electrodes of the LEDs. Transparent row lines are then formed along the rows of the mesh to electrically contact the top electrodes in each row. The LEDs within any cell can be turned on by address in a pair of row and column lines. Phosphor dots may be printed to over blue-emitting LEDs to create red, green, and blue sub-pixels for a full color display.Type: GrantFiled: September 2, 2015Date of Patent: June 14, 2016Assignee: Nthdegree Technologies Worldwide Inc.Inventors: Bradley S.
