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.
