ABSTRACT:
A suspended ceiling sign is provided for suspension within a vacant panel area, under a light fixture, in a suspended ceiling of a regular array of ceiling panels with each panel being peripherally supported within a suspended grid structure. The ceiling sign includes a hollow enclosure having an open top with a peripheral flange configured to engage the supporting grid structure around the vacant panel area. The enclosure has in one of its sidewalls a cutout portion with a translucent sign mounted therein. The bottom of the enclosure has a directed lighting aperture. Inside the enclosure, there is a truncated pyramidal baffle which is both light reflective and translucent. The pyramidal baffle is seated over the aperture in the enclosure bottom. The truncated top of the baffle may be either open or closed with a translucent material. Thus, light emanating from the lighting fixture above the suspended ceiling is partly reflected from the baffle face through the translucent sign, and partly diffused through the translucent baffle to light the aperture in the bottom of the enclosure.
