Abstract
A fiber-based reflective lighting device. The lighting device includes a source configured to generate a primary light, a substrate including a mat of reflective nanofibers, and a light exit configured to emanate the reflected light. The fibers have an average fiber diameter AFD less than 500 nm which diffusively reflects visible light upon illumination with at least the primary light. The mat has a basis weight less than 40 gram per square meter (gsm) and a reflectance greater than 80%.
