Abstract
This disclosure provides systems, methods and apparatus for providing a desired illumination pattern within a given plane. In one aspect, a light wash system can be configured to provide substantially even illumination on a wall or floor. The light wash system can use light-shaping optics such as a stack of optical films to provide a light wash system which is smaller than conventional light wash systems which utilize parabolic reflectors. The light wash system may include an internal retroreflector to allow a wider range of throw distances for the light wash system.
