Abstract

A multi-band LED disinfection system and a multi-band LED disinfection lamp are provided. The multi-band LED disinfection system comprises a multi-band LED disinfection device; and a control terminal, which is connected to and controls the multi-band LED disinfection device. The control terminal sends a wavelength band control command to the multi-band LED disinfection device according to a disinfection target, and the multi-band LED disinfection device drives LED beads of corresponding wavelength bands. Different wavelength bands of ultraviolet light can be provided to achieve the disinfection of various germs, which leads to better sterilization and disinfection effects. A control module can be used to switch between disinfection of a certain wavelength band and disinfection of superposed wavelength bands. The present disclosure has both a sterilization-and-disinfection function, and an illumination-and-warning function, and non-related personnel can be prevented through the illumination-and-warning function from approaching the lamp during the sterilization and disinfection process.
