Before buying a UV lamp for indoor disinfection, you need to understand these points first

In addition to 75% alcohol and various disinfectants, there is actually a good disinfection method that uses ultraviolet light for disinfection. Of course, like masks and disinfectants, УВ лампесу такође оскудни производи. Тешко их је купити за кратко време. Али то’s okay. Before that, everyone needs to be aware of the things that need to be paid attention to when using UV sterilization lamps.

Главни принцип рада ултраљубичасте лампе је коришћење ослобођених ултраљубичастих зрака за инактивацију бактерија и вируса како би се постигао ефекат стерилизације и дезинфекције. Што се тиче специфичног принципа рада ултраљубичасте лампе, биће наведен извор светлости ултраљубичасте лампе. Тренутно постоје углавном два извора светлости: извор светлости са пражњењем гаса и чврсти извор светлости.

НајчешћиУВ лампаs we can buy are gas discharge light sources, mainly low-pressure mercury lamps. Its working principle is the same as that of a fluorescent lamp, except that the mercury vapor in the lamp tube generates ultraviolet rays by energizing the mercury atoms in the tube. Low-pressure mercury vapor generally mainly produces 254 nanometer UVC ultraviolet rays and 185 nanometer UVD ultraviolet rays.

After talking about the disinfection principle of the ultraviolet lamp, we will consider the specific choice next. Generally speaking, 1 cubic meter of УВ лампа should not be less than 1.5W. According to this calculation, assuming your bedroom is 20 square meters and the floor height is 3 meters, then a simple calculation can know that you need to configure a 40W ultraviolet light for your bedroom.

Another thing to note is the material of the tube. At present, there are two main glass materials for low-pressure mercury lamps on the market: quartz glass and high boron glass. The transmittance and radiation of quartz glass are higher than those of high boron glass. The penetration ability of short-wave ultraviolet rays is extremely weak, so be sure to choose quartz glass.
