Title:
STERILIZATION LIGHTING DEVICE INCLUDING HIGH COLOR RENDERING WHITE LED VIRUS STERILIZATION ELEMENT INCLUDING 405 NM LIGHT
Document Type and Number:
WIPO Patent Application WO/2022/181916
Kind Code:
A1
Abstract:
According to the present invention, a light source device exhibiting a sterilization effect against an infectious virus by means of a white LED including 405 nm violet light is a sterilization lighting device that includes white light and violet light having a visible light wavelength of 400-420 nm similar to the Soret band and Q absorption bands of porphyrin, can control the respective light emission intensities of the white and violet light, and provides the effect of inactivating germs such as viruses and bacteria. The present invention is safe for the human body and ecosystems in terms of using visible light, which is different from a UV-C light which is ultraviolet light, and is thus effective for long-term use.
