Abstract:
A light-emitting arrangement including an optical member and a light-transmissive shield member secured with respect to the optical member at least partially defines a light-fixture exterior and having a back side facing a circuit board and receiving a gasket which encircles the circuit board to provide a water seal thereabout. The gasket has a pair of spaced apart outwardly-extending lateral fingers engaging lateral sides of a recess formed by the optical-member back side, and at least one inner finger extending into the recess offset from the recessed lateral sides. A peripheral wall extends from the optical-member back side outwardly around the gasket and engaging an emitter-supporting to minimize water ingress toward the gasket. An opaque shield is disposed along at least a portion of a perimeter of the optical member and configured and dimensioned to minimize or block distribution of light in at least one direction opposite the direction of the primary illumination.
