## Abstract

Lighting panels and methods of manufacturing lighting panels are described. An example lighting panel includes a substrate that has a planar surface, electrically conductive traces printed onto the planar surface of the substrate, and light sources mounted onto the electrically conductive traces at mounting positions such that the electrically conductive traces form an electrical interconnection between selected ones of the electrically conductive traces and associated ones of the light sources. The lighting panel also includes a polymer sheet provided over the light sources, and a composite base upon which a stack-up of the substrate with the printed electrically conductive traces, the light sources, and the polymer sheet is applied. The light sources are embedded into the composite base and are also flush with a top surface of the stack-up, and the substrate is also embedded into the composite base underneath the light sources at the mounting positions.
