Abstract
A luminaire includes an electrical base, an optic, and a heat sink disposed between the base and the optic. An LED driver circuit is disposed at least partially within the heat sink, and is disposed in electrical communication with the base. An LED light source is disposed in thermal communication with one or more surfaces of the heat sink, and in electrical communication with the driver circuit, the LED assembly includes an LED module. The light source includes a printed circuit board with a plurality of projections that are bendable such that the projections are arranged on an angle when assembled on the heat sink.
