United States Patent Fred Katz
Patent Number: US 10,1060,098 B2
Abstract:
Airborne organisms can spread disease. In many indoor
environments, attempts have been made to filter air passing through a
ventilation system. However, in many instances improper maintenance of
these filters can lead to additional problems.
Embodiments of the present invention provide a
configurable light, suitable for institutional usage. The light can be
configured to accomplish a wide variety of lighting tasks and can be
utilized to minimize the presence of pathogens in the environment
where the light is located.
A lighting fixture includes a first compartment
including a light sealed air plenum and a first lighting source
arranged in the plenum to irradiate air passing through the plenum to
destroy pathogens. A second compartment is configured to be external
to the first compartment. A second lighting source is arranged in the
second compartment to illuminate an area adjacent to the second
compartment.
In another embodiment, the first compartment
includes ultraviolet light emitting diodes. The first compartment can
include light containing baffles. The air is preferably forced through
the first compartment using a fan, blower or other air moving device.
The first compartment may include one or more screens and/or filters.
The first compartment can also include a negative ion generator. The
second lighting source can include a configurable array of lights that
provides color for one or more of setting a mood, providing therapy
and promoting healing as well as providing room illumination. A backup
battery and a backup light can be provided for use in power outages. A
radio frequency identification chip can be mounted on the fixture to
permit remote identification of the fixture. The fixture can be
configured to fit into a standard light bay. The fixture can be
controlled remotely either through wiring, an infrared data link or
through a wireless link.
