Suitability of DIALux for designing UVC disinfection cabins

Posted on 19.02.2021 - 17:31
During the present Sars-CoV-2 pandemic, there has been an increase in the development of UVC disinfection systems. Researchers and members of the lighting community moved their interests to this new field to help and develop systems for disinfecting facemasks or other small equipment. In this manuscript we show that it is possible to use DIALux to simulate the irradiance distribution provided by a lamp emitting in the UVC range. We will compare the results provided by DIALux with those obtained from Zemax OpticStudio in three different scenarios. We compared the minimum, maximum, and mean irradiance at the detection plane. The difference between the two software were less than 12%, 2%, and 6% respectively. We also compared the contour maps of isoirradiance lines. We conclude that DIALux is well suited for UVC lightning design in the UVC range. We think that this finding will contribute to increase the design and manufacturing of new UVC disinfection systems needed to fight against the Sars-CoV-2 pandemic.
