ABSTRACT:
A cornice lighting fixture (10) disclosed is designed for use on public transit vehicles (12) and includes a unitary member (20) defining a light housing (22) and a trim panel (24) that extends horizontally and vertically from the light housing. A light cover (28) encloses a fluorescent tube (26) mounted within the housing by an electrical connector support (84). The unitary member defining the housing and trim panel is preferably made as a pultrusion from resin and glass fibers so as to have an elongated shape of a uniform cross-section with the light housing defining an upper and inward longitudinal margin of the fixture and with an outer mounting flange (70) of the trim panel defining a lower and outward longitudinal margin of the fixture. Upon mounting of the fixture, the housing and the trim panel cooperate to partially define an air duct (30) for carrying heated or cooled air. A horizontal wall (44) of the housing has an inward securement formation (50, 52) that receives an upper edge (54) of the light cover while a vertical wall (60) of the housing extends downwardly from the horizontal wall thereof for connection to the trim panel at which connection a cover mounting flange (62) extends inwardly to secure a lower edge (64) of the light cover. The trim panel has a curved shape that is concave with respect to the interior of the vehicle and also has upper and lower tabs (32, 34) for mounting an advertising sign thereon so that light shining through the cover illuminates the sign from its front side.
