  • Patent number: 11872331
    Abstract: An example embodiment of an upper room air germicidal light fixture may comprise a light source configured to emit germicidal light and may further comprise one or more lower and upper baffle assemblies disposed adjacent to the light source. Said upper and lower baffle assemblies may be configured to enable air to flow through them and to block or substantially dissipate incident light rays from the light source. One or more apertures may be defined by the openings between a corresponding set of upper and lower baffle assemblies, wherein said light can exit the fixture through said apertures. When the germicidal light fixture is disposed in a room, surrounding room air may contact light exiting the apertures of said fixture, and room air traveling through said fixture may contact light inside and between the one or more upper and lower baffle assemblies.
