The principle of pulse light sterilization is the same as that of ultraviolet sterilization, both of which destroy the structure of DNA

However, from the characteristic spectrum of the pulsed light spectrum, it can be seen that only the 254nm characteristic spectrum of the UV lamp is within the effective sterilization area, while the absorption spectrum of DNA has a characteristic spectrum line of 265nm. The pulsed light is full spectrum light, especially in the effective sterilization ultraviolet band (200-280nm), which has the maximum energy output. According to the integrated energy calculation, the instantaneous effective sterilization energy of the pulsed light (207J injection energy) is 100000 times that of the UV lamp energy

Moreover, pulsed light has a strong near-infrared output spectrum, and near-infrared light has a hot wire effect on bacteria. When observing the surface of bacteria irradiated by pulsed light under an electron microscope, significant thermal damage can be observed

UVC sterilization+NIR effect+continuous pulse superposition, pulsed light shows excellent sterilization effect, even spores can be completely killed under a few pulses.
