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.
