The use and its quality assurance of LED UV-A black light

This paper compares different luminous principle of the UV-A LED black light lamp and high pressure mercury vapor arc light, introduces the structure of the LED UV-A black light and filter, lens and other auxiliary structure, and expounds the common failures of the LED black light lamp in the using process, such as illuminance decaying and leakage of white light quality. Some assurance measures for solving the fault were put forward.
