Abstract

Apparatuses having an ultraviolet light lamp are disclosed, where ultraviolet light is projected exterior to the apparatus and, in some embodiments, to a region 2-4 feet from a floor of a room in which the apparatus is arranged. In some cases, an apparatus includes a mobile carriage supporting the lamp and the apparatus is configured such that the lamp is not moveable beyond vertical planes aligned with a casing of the mobile carriage. Additional or alternative embodiments of apparatuses include a housing transparent to ultraviolet light surrounding the lamp and an exhaust duct extending from a gas outlet of the housing into a support structure that has an outlet disposed along its lower half portion or its bottom surface. Other embodiments of apparatuses include a pulsed ultraviolet light lamp and a sensor system to monitor and determine when to replace the pulsed lamp based on pulse count.
