  • Patent number: 8646947
    Abstract: A multicolor illumination device uses a blue or UV light source to excite wavelength conversion materials and a red light source as a direct illumination light. The lights from the two light sources are combined onto a moving wavelength conversion element. The moving wavelength conversion element includes multiple segments alternatingly disposed in the paths of the incident lights, including a first segment with no wavelength conversion material, and other segments which may carry blue, green and/or yellow wavelength conversion materials. A control system controls the on/off of the two light sources so that when the first segment is in the light path, the red light source is on and the blue/UV light source is off, and vice versa when the other segments are in the light path. Alternatively, dichroic filters may be fixedly provided on the segments of the wavelength conversion element to block the blue/UV or red light.

  • Patent number: 8573823
    Abstract: In one embodiment, a solid-state luminaire has a strip of high power LEDs, where each LED emits light into an optical coupler. Light from the optical coupler is then coupled into a light guide. Light coupled into the light guide is mixed and guided to an exit aperture of the light guide. An optical extractor proximate the exit aperture of the light guide redirects light outward, which is optionally redirected generally downward by a secondary reflector that extends outwardly along the length of the light guide. The secondary reflector may be configured to create a variety of light-emission patterns. The luminaire may be hung from a ceiling, in track lighting, used as a pendant or pedestal fixture, or in other applications.
