Abstract:
1. An illumination device comprising: a rigid three-dimensional substrate configured to define an interior region, said three-dimensional substrate having an exterior surface and having an interior surface; a plurality of electrical traces on at least said interior surface, said electrical traces configured to transmit driving signals; a plurality of light-emitting dies mounted on said exterior surface of said three-dimensional substrate and connected to some of said electrical traces, said light-emitting dies being configured to generate light when driving signals are applied to said light-emitting dies through said electrical traces; said three-dimensional substrate includes thru-holes with thermally conductive material therein, each of said thru-holes being positioned directly below one of said light-emitting dies; said three-dimensional substrate includes reflector cups on said exterior surface of said three-dimensional substrate, said light-emitting dies being mounted in said reflector cups; and said interior region being substantially entirely filled with a fluid interfacing with said interior surface and said traces thereon.
