Abstract

Lighting modules and systems including a heat sink are generally disclosed. The exemplary embodiments include a lighting module having a light emitting diode (LED) board including at least one LED, a heat sink in thermal communication with the LED board for dissipating heat generated by at least the LED board, and a separate component board that is thermally insulated from the LED board and may include, for example, an LED driver, a power management component, a power conversion component, an LED control component, and a dimming component. At least one of the LED board and component board may be a printed circuit board (PCB).
