Abstract

A lighting fixture which includes an elongate modular lineal section fabricated of an extruded high-strencth metal alloy. The extrusion comprises an elongate generally flat base integrally joined at a pair of opposed lingitudinal edges thereof to upwardly extending sidewalls. The sidewalls are formed at opposed respective upper edge portions thereof with channel-like upwardly opening grooves for matingly receiving therewithin laterally spaced elongate free edge portions of a lens of a high strength plastics composition. The lens bridges opposed sidewalls of the extruded metal base to complete a lighting fixture housing section or module open at each end. Configured for matingly engaging and for positive attachment to each end of the housing section is a skeletal bridge-like end plate formed with through framed openings. Attachable to each or to either end plate is a skeletal adapter ring for facilitating attachment of an additional housing section or module to provide a lighting fixture comprised of two or more modular housing sections. End caps provide fluid-tight closures of the assembly. In other embodiments of the invention the modular structures may be connected to provide lighting fixtures which form L, T, cross, X, as well as closed-loop configurations.
