Development of Ultraviolet Lamp of'Man-Machine Coexistence'and Experimental Study on Sterilization
An ultraviolet lamp with a wavelength of 222 nm was designed according to the principles of safety,high efficiency and easy installation.The structure of the ultraviolet lamp is introduced,which mainly consists of light source,filter,reflector,circuit module and shell.And it was placed in a closed air chamber filled with white staphylococcus aerosol for sterilization test.The results show that there are almost no surviving staphylococcus albicans in the closed air chamber after ultraviolet lamp continuously irradiating for 2 h.The ultraviolet lamp with a wavelength of 222 nm has a good killing effect on staphylococcus albus,and has a promising application in indoor sterilization.
