Badge assemblies that emanate visible iridescent patterns

摘要

A badge assembly that includes a translucent, polymeric badge comprising an edge and an interior surface with a diffraction grating having a thickness from 250 nm to 1000 nm and a period from 50 nm to 5 microns; LED sources oriented toward the edge; and fascia configured to obscure the sources. Further, the grating diffracts light from the LED sources through the badge as a visible iridescent pattern.
