Abstract

There is provided an improved ultraviolet lamp assembly using an ultraviolet lamp with a vented closed end quartz tube having improved and increased ultraviolet lamp intensity output for increased germicidal and bactericidal effect for use in purification, sterilizing, sanitizing and cleaning systems. The ultraviolet lamp assembly comprises an ultraviolet lamp, a tube operative to house the ultraviolet lamp and comprising a closed end, an open end able to allow insertion of said ultraviolet lamp and having a plurality of vents that allow air into and out of an air space between the ultraviolet lamp and the surrounding tube, a tube divider operatively disposed between said UV lamp and said tube to thereby divide said air space into at least two air space compartments enabling air to circulate through said tube, and an air displacer operatively connected to at least one of said vents and able to produce air flow in said tube.
