This invention describes a device that uses light to kill germs on surfaces. It features a circuit board with special light emitters and an integrated controller to manage their operation. The light emitted is specifically designed to be highly concentrated in the blue-violet spectrum (380-420 nanometers) to effectively inactivate microorganisms.
Why it matters: While LED and microcontroller technologies have seen incremental improvements since 2023, no fundamental shift has occurred to significantly alter the cost or efficacy of this specific germicidal light approach. The primary hurdle likely remains optimizing the balance between effective microorganism inactivation and practical power requirements.
