Indirect area lighting apparatus and methods
Abstract:
A lighting fixture apparatus includes a light source oriented toward a illumination area. A primary reflector is disposed between the light source and the illumination area. The primary reflector includes a primary concave surface substantially facing away from the illumination area. A secondary reflector is positioned opposite the primary concave surface and includes a secondary concave surface substantially facing toward the illumination area. The primary concave surface is substantially specularly reflective, and the secondary concave surface is substantially diffusely reflective. In some embodiments, only reflected light is visible from the illumination area, and no direct light from the light source is incident on the illumination area.
