Title:
OZONE GENERATOR FOR STERILIZATION
Document Type and Number:
WIPO Patent Application WO/2022/038802
Kind Code:
A1
Abstract:
Provided is an ozone generator for sterilization, which exhibits high safety in usage environments such as bactericidal and deodorizing environments and exhibits good user-friendliness. In this ozone generator for sterilization, a mercury-free gas discharge tube array is used as a vacuum ultraviolet radiation surface light source device for generating ozone. The mercury-free gas discharge tube array is configured by arranging a plurality of gas discharge tubes in parallel on an electrode substrate having a common electrode pair, each of the gas discharge tubes housing a noble gas that emits vacuum ultraviolet radiation and having an ultraviolet radiation reflection layer formed on the inner wall surface of the tube on the back surface side. By disposing a ventilation fan directly opposite a light-emitting surface, it is possible to efficiently clean contaminants deposited on the light-emitting surface and cool the light source device.
