Abstract
A window covering system includes a plurality of horizontal slats which are tiltable to control entry of light. The slats include a light processing section which may be a transparent or translucent plastic and an opaque section which may be aluminum. In cross-section, the slats have a complex curvature which processes and diffuses light into the interior while preventing direct light beam penetration to the interior.
