Abstract:
1. A back panel of a light emitting diode (LED) lighting assembly comprising: a heat sink comprising a thermally conductive substrate, the thermally conductive substrate comprising a first major surface and an opposite second major surface, wherein the first major surface has a first edge along a first direction and a second edge along a second direction perpendicular to the first direction, wherein the heat sink is configured to support a LED panel and an optics panel over the first major surface along a third direction perpendicular to the first and the second directions; a plurality of fins extending away from the second major surface and disposed on the thermally conductive substrate, wherein the plurality of fins comprise a first fin, a second fin, and a third fin, wherein the first fin and the second fin comprise a length along the first direction longer than a width along the second direction, wherein the first fin is parallel to the second fin, and wherein the second fin is oriented at a first angle to the third fin; and a groove on the second major surface, wherein the groove is spaced away from the plurality of fins along the second direction, wherein the thermally conductive substrate is thinner at the groove than at a location directly below the plurality of fins, and wherein the groove is configured to receive a mounting plate.
