Abstract: LED lighting modules have a highly thermally conductive polyhedral body having a plurality of exterior facets disposed around a mounting axis in a polygonal array facing outwardly away from the mounting axis and at a downward angle thereto. At least a majority of the facets carries at least one LED whose optical axis is angled acutely. The body carries a plurality of heat dissipating fins and serves as a heat sink to prevent overheating the LEDs in a transient and steady state operation. For retrofit applications, the module is mounted to a fixture via either a support or a bracket in a mounting position in which the elevation of the LEDs is determined according to the mounting and geometry of the replaced lamp.

Abstract: An LED recessed lighting apparatus has a housing mountable in a recess located behind a recess opening in an architectural structure. A non-vented trim is securable in place over the recess opening. A lens that allows light from the LED to pass through the trim has a fluid-tight internal cavity containing at least the light-emitting portion of the LED. At least a major portion of the heat generated by the LED is carried directly from the LED to the outside surface of said trim by way of a thermal path that includes a first heat sink located substantially immediately adjacent and intimately thermally conductively coupled to the LED, at least one second heatsink supported by and substantially directly thermally conductively coupled to, the inside of the trim, and at least one heat pipe thermally connecting the first heat sink to the second heat sink.
