【摘要】：目的观察LED紫外线灯杀菌效果及其影响因素。方法采用载体定量杀菌试验方法,对杀菌效果及其影响因素进行试验观察。结果用LED紫外线灯在垂直2~5 cm处照射5 min,对染菌载体上金黄色葡萄球菌杀灭率均为100%。在垂直2~4cm处照射15 min以上,对载体上大肠杆菌的杀灭率均达到100%。该紫外线灯随着照射距离由2 cm增加到6 cm,紫外线辐射强度由9.2μW/cm~2降低到1.9μW/cm~2;在相同距离随照射时间延长,杀灭效果也相应提高。结论该LED紫外线灯具有良好的杀菌效果,此类紫外线灯具有很好的发展空间。
[Abstract]:Objective to observe the bactericidal effect of LED ultraviolet lamp and its influencing factors. Methods the carrier quantitative germicidal test was used to observe the germicidal effect and its influencing factors. Results LED ultraviolet lamp was used for 5 min in the vertical area of 2cm. The killing rate of Staphylococcus aureus on the carrier was 100%. When exposed to vertical 2~4cm for more than 15 min, the killing rate of Escherichia coli on the vector was 100%. With the increase of irradiation distance from 2 cm to 6 cm, the ultraviolet radiation intensity decreased from 9.2 渭 W/cm~2 to 1.9 渭 W / cm ~ 2, and the killing effect increased with the increase of irradiation time at the same distance. Conclusion the LED ultraviolet lamp has a good bactericidal effect, and this kind of ultraviolet lamp has a good development space.
