摘　　要：遵循安全、消杀高效并且安装方便的原则,设计出一款发光波长为222 nm的紫外灯。其主要由光源、滤光片、反光罩、电路模块和外壳构成。并将该紫外灯置于充满白色葡萄球菌气溶胶的封闭气室中进行杀菌试验。结果表明:紫外灯在封闭气室中持续照射2 h后,几乎没有存活的白色葡萄球菌。发光波长为222 nm的紫外灯对白色葡萄球菌具有良好杀灭效果,在室内杀菌消毒方面具有应用前景。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.
