Abstract: An LED light fixture including a housing portion and a base together defining an open space therebetween permitting air/water-flow therethrough. The housing portion forms a chamber enclosing at least one driver. The base extends from the housing portion and supports at least one LED illuminator outside the chamber. The housing portion and the base may each be formed as part of a one piece with the open space along at least three sides of the base. Alternatively, the base may be a separate structure secured with respect to the housing. Such base may be a single-piece extrusion supporting a plurality of LED modules or comprise a plurality of extruded heat sinks. Each heat sink may support one or more LED modules.

Abstract: An LED light fixture including a housing, a heat sink secured with respect to the housing and an LED illuminator secured with respect to the heat sink. The heat sink includes central and peripheral portions. The central portion has an LED-supporting surface and forward, rearward and lateral sides, the LED illuminator being at the LED-supporting surface. The peripheral portion extends laterally from the lateral sides. The central portion of the heat sink has downwardly-extending shield members at the lateral sides thereof configured and dimensioned to block illumination in a direction opposite the LED illuminator. In embodiments where the optical member is configured for directing emitter light predominantly toward the forward side, the central heat-sink portion has a downwardly-extending shield member at the rearward side thereof configured and dimensioned to block rearward illumination.
