Abstract

A modular lighting assembly for a modular frame piece comprising a power module, a heat spreader, a circuit board with traces that provide electrical pathways, at least one illumination element, and a cover. The circuit board is disposed upon the heat spreader, the cover is disposed upon the circuit board and encapsulates the circuit board, the power module is electrically connected to the traces on the circuit board. The traces on the circuit board are electrically connected to the at least one illumination element to enable power transfer from the power module to the at least one illumination element. The modular lighting assembly can be slidably disposed within a slot of a modular frame profile.
