Abstract
A light fixture includes a core member having a top end, a bottom end, and a body extending between the top and bottom ends. The core member includes a solid, single member or modular members. The body includes outer surfaces (“facets”) spaced along an outer perimeter thereof. Each facet can receive one or more light emitting diode (“LED”) packages in various different positions, with different electrical and other configurations. Heat pipes extending through the core member dissipate heat from the LEDs. Active cooling modules and/or fins may assist with this heat dissipation. The heat pipes and/or a separate elongated structure extending through the core member can secure the core member to the light fixture.
