Paper Abstract

Wall washers are applications that provide illumination effects onto a wall, generated by light sources located close to that wall. Traditionally, incandescent and fluorescent lamps are used to generate a uniform color or a simple pattern. Solid-state-lighting opens up the possibility to generate more complex patterns of light. In this paper, we discuss the design and results of two different prototypes of wall washers that are able to generate a number of rows and columns of individually addressable spots ('pixels') of light onto a wall. Our conclusions focus on the optical performance of the chosen solutions versus the size of the optical system.
