不活化装置および不活化方法
Document Type and Number:
Japanese Patent JP7302644
Kind Code:
B2
Abstract:
An inactivation device and an inactivation method that effectively and more appropriately inactivate microorganisms and/or viruses using ultraviolet rays in a wavelength range in which adverse effects on the human body are suppressed. This inactivation device comprises a light source unit that emits ultraviolet rays having a central wavelength within a wavelength band of 190-235 nm, a detection unit that detects the presence or absence of a human being in a target space, and a control unit that controls the lighting state of the light source unit. The control unit commands to perform ultraviolet radiation for a predetermined period of time during which the detection unit does not detect the presence of a human being. After the lapse of the predetermined period of time, the control unit makes the light source unit stop the ultraviolet radiation. Then, the control unit makes the light source continue to suspend the ultraviolet radiation at least until the detection unit detects the presence of a human being.
