Abstract
In a luminaire comprising an upper housing assembly for a light source and a lower plastic refractor closing the underside and having a rim adapted to mate with that of the assembly, C-shaped latches are disposed around the periphery of said refractor for clamping the rims together when pivoted into position astride both rims. Circumferentially extending bail wires attach the latches to the underside of the refractor rim and allow them to be pivoted into clamping position while preventing them from dropping off when disengaged. The bail wires pass through holes molded in the plastic of the refractor rim.
