초록
코로나 팬데믹 이후 UV 광원을 이용한 공간 살균효과에 대한 연구와 응용이 급속히 증가하고 있다. 본 논문에서는 실내 공간환경 시스템이나 조명장치에 내장할 수 있는 UV-LED 광원의 공간 살균 효과를 조명광학적인 접근을 통해 정량적으로 분석하였다. 이를 통하여 공간 살균력이 우수한 것으로 알려져 있는 275 ± 5 nm 파장 영역의 실내공간 살균 효과 최적화 기반을 마련할 수 있을 것으로 전망한다.
Abstract
Since the coronavirus pandemic, research and application of space-sterilization effects using UV light sources have been rapidly increasing. In this paper, the space-sterilization effect of UV LED light sources that can be built into indoor environmental systems or lighting devices is quantitatively analyzed through an illumination optical approach. Through this, it is possible to establish a foundation for optimizing the sterilization effect in indoorspaces in the 275 ± 5-nm wavelength range, which is known to have excellent space-sterilization power.
