ABSTRACT:
An ultraviolet lamp fixture used in combination with a conventional, commercial vacuum cleaner for the purpose of purifying the air within a room. The air, after being drawn into the vacuum cleaner and having the dirt particles removed, is exhausted into a U-shaped housing which is carried by the vacuum cleaner and which contains a plurality of longitudinally mounted ultraviolet ray tubes. When the air passes over these tubes, micro-organisms contained in the air are killed by exposure to the ultraviolet radiation emitted from the tubes. The purified air is then returned to the room through an aperture in the housing. The ultraviolet light fixture may be adapted to be used with an existing conventional vacuum cleaner as shown in this specification, or a new combination light fixture-vacuum cleaner may be manufactured.
