Abstract
A device which consists of a germicidal ultra-violet lamp (UVGI Lamp) fitted with a flouro-polymer sleeve, which is heat sealed on each end of the lamp but not allowed to seal over the body of the lamp, thereby providing a thermal barrier for more efficient operation of the lamp in colder temperatures. The UVGI is used for disinfecting surface and airborne mold and bacteria, within the line of sight of the light emission of the device and typically placed in air handlers, air conditioning units, air purifiers, or other devices used to move, transport or purify air, water or other fluids.
Claims4
A germicidal ultra-violet lamp (UVGI Lamp) fitted with a flouro-polymer sleeve, which is heat sealed on each end of the lamp but is left loose over the body of the lamp, thereby providing an air barrier between the glass, quartz or other surface of the lamp and the flouro-polymer sleeve for more efficient operation of the lamp in colder temperatures.
A flouro-polymer sleeve, encapsulated over the lamp, and configured such that it traps a layer of air between the flouro-polymer sleeve and the surface of the samp, while forming an air tight seal over each end of the lamp.
Application of an FEP or PTFE flouro-polymer shield over the top of the existing UVGI lamp, cutting the shield to length and applying heat over the length of, and on the edge of the ceramic surface on each end of the lamp, forming a seal over the end sections, but without allowing the flouro-polymer shield to touch or be proximity with the surface of the light emitting portion of the lamp.
A UVGI lamp, covered with a flour-polymer shield, sealed at each end of the ceramic cap and/or additionally sealed at the edges of the ceramic cap, such that the flouro-polymer shield is in contact with and sealing the ends of the lamp, but not in contact and instead maintaining an air barrier around the surface of the UVGI lamp, and without heat shrinking or sealing the flouro-polymer shield over the light emitting surface of the lamp.
