A solution for suppressing organism growth using ultraviolet radiation
generated by solid state ultraviolet radiation emitters, such as
ultraviolet diodes is provided. The invention includes a connection
structure that includes a plurality of solid state ultraviolet radiation
emitters disposed thereon. Each of the plurality of solid state
ultraviolet radiation emitters emits ultraviolet radiation having a
wavelength less than or equal to four hundred nanometers to harm a target
organism that may be present on a surface. In one embodiment, the
connection structure comprises a two-dimensional mesh that may be placed
adjacent an air filter, incorporated in a cover, and/or moved with
respect to a surface, such as the interior of an air duct. In this
manner, the invention can suppress and/or prevent the growth of
organisms, such as biofilms and mold, in locations that are susceptible
to such growth.
