Problems solved by technology

However, whether it is a low-pressure mercury lamp or an ultraviolet light-emitting diode, it can only sterilize the area exposed to ultraviolet light, and the area that cannot be irradiated by ultraviolet light has no disinfection effect, resulting in disinfection "dead spots" remaining in the sterilized space
In order to enhance the disinfection effect and reduce the "dead angle" of disinfection, the usual practice is to install ultraviolet lamps in various parts of the space to be disinfected, which increases the cost of disinfection and does not significantly improve the disinfection effect
At the same time, the existing ultraviolet lamps do not have any degradation effect on the air and toxic organic substances on the surface of the appliance, and the killing effect on viruses, which are simple in structure and have no organelles, needs to be improved urgently

Abstract

The invention discloses an ultraviolet LED air sterilization system which comprises an ultraviolet LED light source module capable of producing ultraviolet light and an annular catalysis plate surrounding the ultraviolet LED light source module. The ultraviolet LED air sterilization system can perform thorough air disinfection.

Description

technical field [0001] The invention relates to an air disinfection system, in particular to an ultraviolet LED air disinfection system. Background technique [0002] Ultraviolet light is a commonly used disinfection equipment, which can effectively kill bacteria, viruses, spores and other pathogens in the air and on the surface of tools. It is widely used in the disinfection and sterilization of households, medical institutions, sterile rooms and other spaces. Ultraviolet light-emitting diodes have the advantages of long service life, high light intensity, and low energy consumption, and are widely used in the field of disinfection. However, whether it is a low-pressure mercury lamp or an ultraviolet light-emitting diode, it can only sterilize the area exposed to ultraviolet light, and the area that cannot be irradiated by ultraviolet light has no disinfection effect, resulting in disinfection "dead spots" remaining in the sterilized space . In order to enhance the disinf...
