Abstract

A recessed wall wash light fixture includes a light source and a hollow light guide. The hollow light guide has a reflective internal surface and forms upper and lower apertures along its upper and lower boundaries. The lower aperture is slanted upwardly in the forward direction. The hollow light guide includes a forward section and a rear section having respective centerlines and wall surfaces. Both of the centerlines are concave with respect to one another, and the wall surfaces extend laterally from the centerlines and curve toward one another. The forward and rear wall surfaces substantially meet one another at midlines that extend downwardly from the upper aperture to the lower aperture.
