The mechanism of the action of the blue lamp

The blue lamp is a quartz mercurya discharge lamp that emits ultraviolet waves in the range of 205 to 315 nm. This range of ultraviolet waves gives a blue emission spectrum, which is why the lamp is called blue. Ultraviolet waves of this particular radiation spectrum destroys DNA structure, protein and biological membranes of microorganisms destructively, which in turn leads to the death of some of the microorganisms exposed to radiation. The rest is divided, but as a result of DNA changes, part of the next generation of microorganisms also perishes. Within 2-4 weeks after irradiation, either the final death of all microorganisms or the restoration of their former quantity may occur. Possibility of the latter also explains the requirement of regularity of quartz of premises. It is worth noting that microorganisms react to the quartz process to varying degrees. The most sensitive to the radiation of a quartz lamp are sticks and cocci, but the fungi and protozoa are less sensitive. The spore forms of bacteria that are most resistant to radiation are found even in the upper layers of the atmosphere that are most exposed to the natural radiation of this spectrum.

The principle of using a blue lamp at home

The period for which the optimaldisinfecting effect for an open lamp, is from 15 to 30 minutes, for a shielded lamp - 1-2 hours. In this case, an open quartz lamp is used during the day for short sessions of 15-30 minutes, respectively. A closed (shielded) lamp, provided it is well ventilated indoors, can work continuously. At home, open quartz lamps are most often used. There are a number of precautions that must be followed when using an open quartz lamp. During quartz, such a lamp should exclude the possibility of finding people, animals and plants in the room. To avoid burns of the cornea of ​​the eye, do not look at an open lamp. During the operation of the quartz lamp, the air in the room is ionized and a large amount of ozone is formed, which negatively affects the human respiratory system. Therefore, after a quartz session, the room should be ventilated. The action of the quartz lamp applies only to microorganisms within the radiation of the lamp, therefore it is necessary to use the lamp in combination with other methods of disinfection.
