Abstract
A luminaire includes a housing having an external surface and an internal surface defining an interior volume, with an LED light source mounted on a mounting surface within the interior volume, an internal inter-surface structure within the interior volume in thermal communication with the board and in thermal communication with at least one housing internal surface. The internal inter-surface structure configured to spread heat generated by the LED light source laterally along the internal inter-surface structure. The interior volume of the housing is substantially closed to external air flow. The housing external surface being an about smooth surface free of extruding heat sink fins or ridges, and having a shape sufficient to inhibit the trapping of water or dirt.
