Disinfection using far UV-C rays

The New Type Coronavirus (Covid-19) epidemic that we have been experiencing since the beginning of 2020 has affected the whole world, and the methods given to the eradication of infectious diseases have increased even more. Covid-19 epidemic, which has mutated in recent days, poses a significant problem because people spend most of their time indoors and because pathogens (viruses, bacteria and fungi) that cause many infectious diseases spread rapidly in indoor environments. Improvement of indoor air quality; It is also of great importance in terms of economic losses due to human health, job loss and medical treatments. It is of great importance that the UV-C systems used while removing the said pathogens from the ambient air have a structure that will not harm human health. Traditional UV-C production methods produce harmful rays for human health, cannot fully disinfect the air and consist of power systems that require a lot of energy. The use of remote UV-C forming LEDs, which have been used in recent years, is an effective new method that is preferred in improving indoor air quality and controlling infectious diseases by producing rays that will cause less harm to human health, inactivation of all pathogens carried to the indoor environment by air, in an efficient manner. It is a new method. In this thessis, besides the effective design of new generation UV-C systems, LEDs radiating at different wavelengths and 222nm wavelength LEDs, reducing energy consumption and increasing disinfection performance, UV-C radiation areas and UV-C dose distributions were examined.
