ABSTRACT:
A reflector (10) includes a frame (20) and reflector pieces (40, 50). The frame (20) is made of a light-opaque material and the reflector pieces (40, 50) are made of semi-light-transparent materials, preferably color tinted. The frame (20) includes frame portions (22, 24, 26, 28) that are, in cross-section, L-shaped members that support and cover the edge of a flat object when that object is placed within the frame (20). The frame (20) includes a plurality of bands (32, 34, 36). Between the bands (32, 34, 36) are voids (33, 35). The bands (32, 34, 36) include rearwardly extending posts (38). A first reflector piece (40) includes a reflector surface (42) surrounded by a flat border (44). The reflector surface (42) is made up of a plurality of pyramidal elements (46), that are intended to reflect light back toward a light source in a generally light-scattering and diffusing manner. The border (44) of the first reflector piece (40) includes a plurality of apertures (48), each of which corresponds to a complementary post (38).
