Ultraviolet germicidal irradiation system

Abstract

A modular germicidal light system for use in a plenum of a cooling apparatus in which an entrained stream of air flows in a predetermined direction. The system comprises a support assembly comprising at least one elongate member; at least one lamp assembly constructed and arranged to mount to at least one elongate member of the support assembly, and comprising a linear germicidal light source having a longitudinal axis extending at an acute light angle relative to a plane substantially perpendicular to the direction of the flow of said stream of air. Each of said at least one elongate members has a longitudinal axis, and a distal end and a proximal end along said longitudinal axis. The system further comprises one or more anchor members for receiving at least one of the ends of each elongate member for connecting said members to an interior surface of the plenum.

1 . A modular germicidal light system for use in a plenum of a cooling apparatus in which a stream of air is entrained and flows in a predetermined direction, the system comprising:
