ABSTRACT:
A ceiling-mounted, recessed strip lighting fixture (10) is disclosed for mass transit vehicles. An uninterrupted lens module (18) extends throughout the length of two or more spaced apart lamp housings (14a,14b) which are recessed into the ceiling (142,142'). The lens module comprises a central lens section (92) and a pair of oppositely disposed side lens sections (94,94') and is surface-mounted, relative to the ceiling, beneath the lamp housing. The central lens section is a light diffuser for distributing light along the entire length of the lens module. The side lens sections comprise prismatic lens elements for directing the light laterally of the lens module. The side lens sections support the central lens section in a sliding interlocking connection. The central diffuser section may be made up of plural parts which are disposed in end-to-end abutting engagement. The lens module is mounted on the lamp housing by a pair of spaced mounting tracks each of which includes a groove for receiving a connector tongue at the outboard edge of the side sections of the lens module.
