Abstract: A light fixture includes a housing forming a cavity to permit airflow therethrough. A filter is disposed within the airflow of the cavity. An ultraviolet light emitting diode is disposed within the cavity and is directed to concurrently treat the airflow and the filter to destroy biomaterial therein.

Abstract: The present invention is directed to a reusable, single-source, high-power LED module utilizing a subset of components that may be quickly replaced in the field without tools when the useable life of an LED chip expires. The reusable LED module may be used with a variety of lamp assemblies to generate an even wider variety of light distributions. In particular, drive currents, color temperatures, LED bin codes, optical lenses, and lamp assemblies may be varied to achieve a desirable light distribution.
