LED LIGHT FIXTURE WITH INTEGRATED LIGHT SHIELDING

摘要

An LED light fixture (10) including a housing (17), a heat sink (42) secured with respect to the housing and an LED illuminator (41) secured with respect to the heat sink. The heat sink includes cental and peripheral portions (45, 46). 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 (46) extends laterally from the lateral sides (50). The central portion (45) of the heat sink has downwardly-extending shield members (65) 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.
