  • Patent number: 8360605
    Abstract: A luminaire for lighting an area includes at least one LED and a first reflector disposed substantially within the housing. The first reflector includes an annular reflective surface having a central axis and an edge defining an aperture through which light exits. The annular surface is formed from a first conic cross section portion revolved about the central axis with one of the at least one LED facing the central axis and positioned proximate a focal point of the first conic cross section portion. The luminaire also includes a second reflector within the housing. The second reflector has a bottom reflective surface that is formed from a second conic cross section portion extending to and revolved about the central axis. The focal point of the second conic cross section portion is proximate the one of the at least one LED.

  • Patent number: 8317367
    Abstract: A light fixture includes a solid state light emitter having first and second light-emitting portions configured to emit first and second portions of the light, respectively. The light fixture also includes a reflector having a first reflective surface positioned in the path of the light and including a first substantially parabolic section configured to reflect the first portion of the light, and a second substantially parabolic section adjacent the first substantially parabolic section and configured to reflect the second portion of the light. The second substantially parabolic section has a focal length greater than that of the first substantially parabolic section. The light fixture also includes a stray light reflector having a second reflective surface facing the first reflective surface. The first reflective surface reflects a part of the light toward the stray light reflector, and the stray light reflector is configured to reflect the part of the light.

  • Patent number: 7794119
    Abstract: The invention provides a light fixture including a solid state light emitter coupled to a housing and configured to emit light in a path, and a reflector. The reflector includes a reflective surface positioned in the path of the light emitted by the solid state light emitter, the reflective surface comprising a first substantially parabolic section configured to reflect a first portion of the light, the first substantially parabolic section having a first focal length. The reflective surface further includes a second substantially parabolic section adjacent the first substantially parabolic section and configured to reflect a second portion of the light, the second substantially parabolic section having a second focal length greater than the first focal length.
