Abstract
Ultraviolet lamp, one of the many disinfection methods brought to the agenda with the Covid-19 pandemic has been widely used both in our country and around the world. However, the theoretical background of this technology and the calculation methodology of UV disinfection systems are not well known.
In this study, general definitions about ultraviolet lamps (UV lamps) are given and calculation methods of values such as shape factor, UV dose and lamp inactivation rate required for design are explained. In addition, a computer model was created in Java programming language in order to examine different lamp configurations and behaviors. Within the scope of the study, UV lamps with the same total irradiance power were modeled by placing them in a section in different configurations and efficiency, shape factors and inactivation rates were compared in each case.

Abstract
Covid-19 pandemisi ile birlikte gündeme gelen birçok dezenfeksiyon yönteminden biri olan ultraviyole lamba (morötesi lamba) hem ülkemizde hem de dünya genelinde çok yaygın bir şekilde kullanılmaya başlanmıştır. Buna rağmen bu teknolojinin teorik altyapısı ve dezenfeksiyon amacıyla kullanılması durumunda hesaplama metodolojisi fazla bilinmemektedir.
Bu çalışmada ultraviyole lambalar (UV lamba) ile ilgili genel tanımlar verilmiş, tasarım için gerekli olan şekil faktörü, UV dozu, lambanın öldürme oranı gibi değerlerin nasıl hesaplanacağı anlatılmıştır. Ayrıca farklı lamba konfigürasyonlarını ve davranışlarını inceleyebilmek için java programlama dilinde bilgisayar modeli de oluşturulmuştur. Çalışma kapsamında toplam ışınım gücü aynı olan UV lambalar farklı konfigürasyonlarda bir kesit içerisine yerleştirilerek modellenmiş ve her durumundaki verimleri, şekil faktörleri ve öldürme oranları karşılaştırılmıştır.
