Abstract
A wall wash lighting fixture includes a light source, a light pipe below the light source and a reflector offset from and surrounding the lower end of the light pipe. The lower end of the light pipe has an oblique, light-emitting face that provides uniform wall illumination up to a high vertical angle. The reflector faces substantially away from the wall and provides room-side illumination below about 45 vertical degrees. A preferred embodiment is suited for retrofit recessed installation, especially where small-aperture downlights are desired.

A wall wash lighting fixture for installation near a wall, comprising:
- a light source;
- a light pipe below the light source, the light pipe comprising a light-receiving upper end adjacent the light source and a lower end having a slanted light-emitting face with a high point and a low point, the slanted face obliquely facing the wall with said high point closer to the wall than said low point when the lighting fixture is installed;
- and
- a reflector at least partially surrounding the lower end of the light pipe from said high point downward toward said low point, the reflector facing substantially away from the wall when the lighting fixture is installed to redirect a portion of the light emitted by the slanted face of the light pipe away from the wall.
A wall wash lighting fixture for installation in a ceiling near a wall, comprising:
- a housing having a central longitudinal housing axis;
- a light source within the housing having a central longitudinal light source axis substantially parallel to and offset from said housing axis;
- a light pipe within the housing and below the light source, the light pipe having a central longitudinal light pipe axis substantially coaxial with said light source axis and comprising a light-receiving upper end adjacent the light source and a lower end having a slanted light-emitting face obliquely facing the wall when the lighting fixture is installed;
- and
- a reflector within the housing at least partially surrounding the lower end of the light pipe and facing substantially away from the wall when the lighting fixture is installed to redirect a portion of the light emitted by the slanted face of the light pipe away from the wall, the reflector having a central longitudinal reflector axis substantially coaxial with said housing axis.
