Abstract

A method of making illumination systems for illuminating building interiors comprises positioning first and second opaque, rigid reflective side walls at a distance from one another with reflective surfaces facing each other. The method further comprises positioning a reflective grid panel with parallel longitudinal walls and parallel transverse walls joining the longitudinal walls between the side walls, defining rectangular light-transmitting openings. The method also includes positioning an LED light source above the grid panel to illuminate it at incidence angles ranging from 0° to at least 45°. Additionally, the method comprises positioning a light diffusing sheet of optically transmissive dielectric material approximately coextensive with the grid panel parallel to the grid panel between the side walls above the grid panel. The transverse walls of the grid panel and the reflective side walls are configured to diffusely reflect portions of light transmitted through the rectangular openings.
