LED lighting unit

摘要

An LED lighting unit may include a flexible circuit substrate having a an obverse side and a reverse side. The obverse side may include a plurality of mounting points for LEDs and the reverse side may include a thermal conduction material. A plurality of LEDs may be mounted to the plurality of mounting points and may be in thermal communication with the thermal conduction material. A heat sink may be attached to the reverse side of the substrate and may have a hollow conical-frustum geometry. The heat sink may include a top circumference, a bottom circumference, a top opening, a bottom opening, at least one cooling fin extending into an interior of the heat sink.

1. A lighting unit comprising:
a flexible circuit substrate having a an obverse side and a reverse side, the obverse side including a plurality of mounting points for light emitting diodes (LEDs) and the reverse side including a thermal conduction material; a plurality of LEDs mounted to the plurality of mounting points and in thermal communication with the thermal conduction material; a heat sink having a hollow conical-frustum geometry, a top circumference, a bottom circumference, a top opening, a bottom opening, at least one cooling fin extending into an interior of the heat sink, and an exterior surface which is attached to the reverse side of the substrate, wherein the bottom circumference is less than the top circumference; an LED driver disposed on a tab of the substrate; wherein the heat sink comprises a slot and wherein the tab is inserted into the slot such that the LED driver is disposed inside the interior of the heat sink.
