1. A flexible ultraviolet (UV) light generation system comprising:
a flexible circuit including multiple ultraviolet light emitting diodes (UV-LEDs); and
a UV diffuse reflective layer adjacent to the multiple UV-LEDs, wherein the UV diffuse reflective layer is flexible, wherein the UV diffuse reflective layer includes multiple openings, and wherein each UV-LED is positioned at a corresponding opening; and
a flexible overlayer adjacent to the UV diffuse reflective layer, wherein the flexible overlayer is an encapsulating UV transparent or UV transmissive scattering layer; and
wherein the flexible circuit, the UV diffuse reflective layer and the flexible overlayer are joined or adhered to form a composite structure.
