Abstract
A solid state, recessed light fixture for residential and commercial lighting applications. The fixture includes a truncated cone-shaped trim having a concave bottom surface and a convex top surface, wherein the trim has a sloped circumferential wall that leads to a flat, annular lip at its periphery. An LED array is mounted to the underside within the concave bottom surface and a LED driver is mounted to the top surface. A cover with an open bottom partially encloses the LED driver and a junction box with cable openings and knock out ports is stacked on top of the cover. The cover is a thermal insulator to contain heat from the LED driver inside while the trim acts as a thermal conductor and radiator for the LED driver. No “can” housing is needed to enclose the fixture, and no finned, heat sink is needed to dissipate heat.
