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: 11353167Abstract: A variety of light-emitting devices for general illumination utilizing solid state light sources (e.g., light emitting diodes) are disclosed. In general, the devices include a scattering element in combination with an extractor element. The scattering element, which may include elastic and/or inelastic scattering centers, is spaced apart from the light source element. Opposite sides of the scattering element have asymmetric optical interfaces, there being a larger refractive index mismatch at the interface facing the light emitting element than the interface between the scattering element and the extractor element. Such a structure favors forward scattering of light from the scattering element. In other words, the system favors scattering out of the scattering element into the extractor element over backscattering light towards the light source element.Type: GrantFiled: May 14, 2021Date of Patent: June 7, 2022Assignee: Quarkstar LLCInventors: Roland H. Haitz, George E. Smith, Robert C. Gardner, Louis Lerman
