Abstract
Methods and systems for thermal management of one or more LEDs are disclosed. One or more LEDs may be coupled with an external layer of a thermal ground plane according to some embodiments described herein. For example, the one or more LEDs may be electrically coupled with a circuit carrier with one or more electrically conductive traces etched therein prior to coupling with the thermal ground plane. The thermal ground plane may be charged with a working fluid and/or hermetically sealed after being coupled with the LED.
