Single diode disinfection

This invention describes a light device designed to kill germs. It works by using an array of chip-on-board light emitters that first produce a blue-violet light. This blue-violet light then shines through two different materials that convert portions of it into other colors, which then mix with the original blue-violet light to create a disinfecting white light.

Why it matters: The underlying LED and phosphor technologies were mature by 2023. No specific technological shift in the last three years has fundamentally altered the challenges of balancing disinfection efficacy, white light quality, and cost for this specific approach.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom LED array, phosphor layers, chip-on-board assembly
