Abstract
A fully recessed unit equipment luminaire for providing emergency lighting to a path of egress. The luminaire has batteries, a battery box, a housing, a charger/emergency switching circuit mounted on a chassis, lamps, reflector assemblies, and a cover. The luminaire may be configured for either wall or ceiling mounting with the use of wall or ceiling mount lenses, respectively. Reflector assemblies supporting the lamps are rotatably engaged by the cover. Each reflector assembly has a substantially semi-frustoconical shape and intersects the lamp's conical shaped beam of light to redirect the beam into a narrow, elongated pattern. The reflector assemblies may have a plurality of planar reflecting surfaces which approximate the semi-frustoconical shape.
