    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.

  • Patent number: 8419211
    Abstract: A lamp tube includes a lamp shade, connectors fixed to opposite ends of the lamp shade, and a circuit board received in the lamp shade and electrically connected with the connectors. At least two resilient members protrude from opposite sides of the circuit board. Each resilient member is resiliently deformed and urged into contact with an inner surface of the lamp shade. The deformation of the at least two resilient members is for providing a spring push force to the circuit board, thus causing the circuit board to tightly engage the inner surface of the lamp shade, thereby retaining the circuit board in position inside the lamp shade.
