A light fixture lens mounting system includes a lighting fixture body having an opening, a lens, and a lens mounting ring having structure for supporting the lens over the opening, the body opening and the lens mounting ring being fitted with a series of corresponding lugs for interlocking engagement. Preferably, the body lugs project outwardly from a rim to form an outwardly open groove and the ring lugs project inwardly from the ring to form an inwardly open groove to permit interlocking engagement of the body lugs in the ring groove and the ring lugs in the body groove. In particularly preferred forms, the body lugs include structure for supporting a gasket adjacent the lens to provide a weathertight seal. In other preferred forms, the body lugs extend inwardly to form an inwardly open groove, and the rings project outwardly from the ring to form an outwardly open groove to permit interlocking engagement of the body lugs in the ring groove and the ring lugs in the body groove. Still other particularly preferred forms provide a three-part weatherproof system for sealing the interior of the fixture, in which the body and ring are configured to permit interlocking of the lugs and ring adjacent the fixture interior. A gasket is supported outwardly from the locking structure, and the fixture body includes structure overhanging the ring. |
