LED assembly with vented circuit board

摘要

A light emitting diode (LED) assembly with a vented printed circuit board is disclosed. A printed circuit board assembly may include a plurality of LED modules disposed in an array with a multilayered substrate and a plurality of vents. The multilayer substrate may include a thermal cooling layer which is in thermal communication with the LED modules for heat dissipation. The multilayer substrate may include one or more electrical power layers in electrical communication with the LED modules for energizing the LEDs. The multilayered substrate may have an external insulating layer that includes a plurality of fluid apertures configured for fluid communication with the thermal cooling layer.
