Optimization of Irradiation Field of Ultraviolet Germicidal Irradiation (UVGI) Device in the Indoor Upper-Room
Existing researches shown that the ultraviolet light at wavelength of 254 nm could inactivate the COVID-19. The parabolic reflector, a key component of the upper-room ultraviolet germicidal irradiation (UVGI) device, plays a vital role in the collimation and restraint of ultraviolet light. This study aims to simulate the collimation effect of four types of parabolic reflectors. They were divided into two categories to compare and analyze the uniformity of irradiance according to the exiting widths and overall heights. The results show that better parallel light can be obtained by placing the lamp at the focal point of the reflector. Increasing the overall height of the reflector can improve the distribution of the irradiation. The improved compound parabolic reflector (d) has higher efficient average value of light constraint and irradiance spatial distribution compared to the other types of reflectors.
