  • Embodiments disclosed distinguish the present invention from prior art substantially and significantly.
  • An embodiment includes Polytetrafluoroethylene (PTFE) Reflectors: The use of reflectors increases the effectiveness and UV intensity. Reflectors maximizes internal reflection to take full advantage of the U V energy or photons emitted from the light source.
  • PTFE is one of the few known materials that have radiation profile shaping elements that can improve performance and reflectivity. It can also be an economical way of intensifying the Ultraviolet Germicidal Irradiation (UVGI).
  • UVGI Ultraviolet Germicidal Irradiation
  • Porous PTFE is an excellent material choice for UV reflectivity because of its resistance to degradation, high reflectivity, and diffuse (Lambertian) reflectance.
  • Porous PTFE exhibits a near-perfect diffuse reflectance, resists degradation from U V light, can be molded into complex shapes, and is chemically inert, making it an attractive material for light spreading applications.
  • the resistance of PTFE to UV light can be partly attributed to the strength of the carbon-fluorin e bonds found in the material. Thickness is a critical parameter because of the mechanism of diffuse reflection. A thicker material will cause the UV to have more reflection within the porous PTFE structure before the light is able to pass completely through the material.
  • Microporous PTFE sheet at 3 mm thickness exhibits total reflectance of over 99% in the UV and visible range, as well as close to 100% diffuse reflectance.
  • PTFE has low UV radiation absorption properties in the 250 nm to 500 nm range. At wavelengths below 240 nm, PTFE begins to absorb U V light as carbonification begins to occur on the surface layer of the material, and chemical bonds there are severed.
  • the reflectance of porous PTFE in the UV range is not only excellent but also the reflected energy is nearly perfectly Lambertian, i.e. diffuse reflectance.
  • a common material used in commercial UV disinfection systems are stainless steel and aluminum. While these materials are highly resistive to microbial growth, stainless steel only has 20 - 28% reflectance of UV light and aluminum, 80% reflectance. However, PTFE provides more than 95% reflectance of the UVC light making systems constructed of these materials more than three times effective than traditional reflectors. Aluminum is useful for applications that require spectral reflectance, but it does not produce a uniform Lambertian distribution of light like PTFE does.
  • An embodiment includes a UV Intensity Sensor: In order to operate the UV system efficiently and to obtain a consistently good curing result, careful monitoring of the UV output is extremely crucial. If the lamps are only replaced at set time intervals which is the conventional method, they may be replaced too soon or too late, creating needless waste of resources.
  • the UV intensity sensor continuously monitors UV lamp intensity of a single lamp, it establishes preventive maintenance schedules for lamp systems and determines when to replace a lamp, as well as collects data for statistical process and quality control. When the UV lamps and reflectors are new, the display is set to show a 100% relative intensity. A decrease in the displayed percentage shows the gradual degradation in the UV lamp’s output compared to its output when new.
