Abstract
A lighting device (e.g., a controllable light-emitting diode illumination device) may have a light-generation module that may be assembled and calibrated prior to the light-generation module being installed in a finished good. The light-generation module may include an emitter module having at least one emitter mounted to a substrate and configured to emit light. The light-generation module may include a first printed circuit board on which the emitter module may be mounted and a second printed circuit board on which those circuits that are essential for powering the emitter module may be mounted. The light-generation module may include a heat sink located between the first printed circuit board and the second printed circuit board. The emitter module may be thermally-coupled to the heat sink through the substrate and the first printed circuit board.
