Multiple light emitter for inactivating microorganisms

This device uses multiple light sources to create a disinfecting light that appears white. One light source specifically emits violet or near-ultraviolet light (380-420 nm) to inactivate microorganisms, without any light-converting material directly in its path. Other light sources and a light-converting material contribute to the overall white light output.

Why it matters: Filed in 2020, the sustained public awareness of pathogen transmission has continued. Advances in LED technology for specific germicidal wavelengths (380-420nm) and visible light have made integrated white-light disinfection systems more efficient and accessible since then.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateLight emitters, phosphor, control electronics
