Small aperture recessed wall wash downlight

摘要

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.

主权项

1. 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.
