Abstract
A lighting device includes a substrate, a light emitting diode (LED) array mounted on a first surface of the substrate, and circuit components mounted on the first surface of the substrate and coupled to the LED array wherein the circuit components are adapted to control electrical power applied to the LED array. A heat exchanger is mounted on a second surface of the substrate and a reflector is disposed about the LED array wherein the reflector has a reflection surface that is convex on a first side of an inflection locus and concave on a second side of the inflection locus, and wherein the first side of the inflection locus is proximate the LED array. A diffuser is adjacent the second side of the inflection locus of the reflector.
