Abstract
A luminaire includes a housing, a light diffusion panel, a reflective surface, and a plurality of light sources. The light diffusion panel includes a light source aperture, an edge surface bounding the light source aperture, and an emission surface. The emission surface includes first and second emission surface sections. The second emission surface section is disposed on an opposite side of the light source aperture from the first emission surface section. The reflective surface is disposed on a side of the light diffusion panel opposite the emission surface. The light sources project light into the light diffusion panel through the edge surface. The light sources include first and second light sources. The first light source projects light into the light diffusion panel and through the first emission surface section. The second light source projects light into the light diffusion panel and through the second emission surface section.
