Abstract
A luminaire having a diffuser structure configured to adjust a shadow cast from one or more LED light sources such that the shadow cast has a gradated transition between an area of illumination and an area of shadow. Accordingly, diffuser teeth may be configured to cast a plurality of shadows from a plurality of LED light sources such that a complex overlap pattern of shadows from the plurality of LED light sources forms a shadow gradient between an area of illumination and an area in shade.
