Abstract:
1. An air treatment system comprising: a housing defining a chamber, said housing further defining an air inlet at a first end portion of said housing and an air outlet at a second end portion of said housing opposing said first end portion, said chamber providing flow communication between said air inlet and said air outlet; at least one ultraviolet lamp positioned within said chamber, said at least one ultraviolet lamp positioned about a first axis and including a first end and a second end spaced with respect to said first end along the first axis, said at least one ultraviolet lamp configured for facilitating inactivating contaminants within air channeled through said chamber; and a light trap coupled to said housing with respect to at least one of said air inlet and said air outlet, said light trap comprising a plurality of adjacent baffle elements defining a tortuous path between adjacent baffle elements, each baffle element of said plurality of baffle elements positioned substantially parallel to the first axis, and a first baffle element of said plurality of adjacent baffle elements having a first width that overlaps a second width of an adjacent baffle element in a direction perpendicular to the first axis to prevent light generated by said at least one ultraviolet lamp from passing through the tortuous path.
