Description

Technical Field

[0001] The invention relates to the technical field of ultraviolet lamp irradiation detection, and more particularly to a device for detecting the irradiation intensity of an ultraviolet lamp. Background Art

[0002] Ultraviolet disinfection lamps are still a commonly used disinfection method. In order to ensure the disinfection effect, it is necessary to regularly test the irradiation intensity of the ultraviolet lamp. When the irradiation intensity of the ultraviolet lamp is lower than 70μW / cm 2 When the ultraviolet lamp is used, it is necessary to replace the ultraviolet lamp in time, otherwise the disinfection effect cannot be guaranteed.

[0003] The current detection method on the market generally uses UV intensity indicator cards for detection, which can only determine whether the UV lamp irradiation intensity is less than 70μW / cm 2 The specific lifespan of a UV lamp cannot be determined. In contrast, using a UV irradiator can accurately measure the UV lamp's radiation intensity and infer its remaining lifespan. However, both testing methods expose the inspector to UV radiation, which poses certain risks. Furthermore, both methods require a 20-minute preheating period for the UV lamp, making it difficult to quickly test a large number of lamps. Summary of the Invention
