ABSTRACT:
An improved light dispersion system for fluorescent lighting fixtures includes a plurality of horizontal diffuser panels suspended below a light source. An upper set of diffuser panels are spaced apart to define a light passageway. A lower diffuser panel is positioned in registration with the light passageway for intercepting and reflecting incident light. Both the upper and lower diffuser panels further scatter transmitted light by refraction. A chromatic lens filter is selectively insertable within the light passageway for modifying the resultant color spectrum.
