1. A method of making a flexible ultraviolet (UV) light generation system, the method comprising:
generating a plurality of openings in a UV diffuse reflective layer,
wherein the UV diffuse reflective layer is flexible;
positioning a flexible circuit adjacent to the UV diffuse reflective layer,
wherein the flexible circuit comprises multiple UV-light emitting diodes (UV-LEDs), and
wherein the multiple UV-LEDs are aligned at corresponding openings of the plurality of openings in the UV diffuse reflective layer;
positioning a flexible overlayer adjacent to the UV diffuse reflective layer,
wherein the overlayer is an encapsulating UV transparent or UV transmissive scattering layer; and
joining or adhering the flexible circuit, the UV diffuse reflective layer and the overlayer to form a composite structure.
