PRODUCT DETAIL


The Germicidal lamp actually belongs to a low-pressure mercury lamp. Low pressure mercury lamps emit ultraviolet light by utilizing a lower mercury vapor pressure (<10-2Pa) to excite, with two main emission spectral lines: one with a wavelength of 253.7nm; The other is at a wavelength of 185nm, both of which are invisible ultraviolet rays to the naked eye.
The Germicidal lamp does not need to be converted into visible light. The wavelength of 253.7 nm can play a very good role in sterilization. This is because there is a rule in the absorption spectrum of light waves by cells. Ultraviolet rays at 250~270 nm have the maximum absorption. The absorbed ultraviolet rays actually act on the cell Genetic material, i.e. DNA. It plays a photochemical role. The energy of ultraviolet photons is absorbed by the base pairs in DNA, causing changes in Genetic material, Make bacteria die immediately or unable to reproduce, achieving the goal of sterilization.
Since ultraviolet ray can kill cells, it is important to pay attention not to directly irradiate people's skin, especially people's eyes, when ultraviolet Germicidal lamp is lit, do not look directly at the lamp tube. Because the short wave ultraviolet ray does not penetrate ordinary glass, wearing glasses can avoid eye injury. If an eye is injured accidentally, it is generally not a big problem, just like being burned by the sun. If it is serious, Eye drop or human milk can be dropped to help recover. In situations with people, do not use ozone tubes, as high ozone concentrations are detrimental to people.
1. Pay attention to blocking valuable indoor calligraphy and painting to prevent long-term ultraviolet radiation, oxidation, and discoloration.
2. When cleaning, cut off the power supply, use a clean soft cloth or alcohol to gently wipe, and avoid using organic solvents such as gasoline.
3. Prevent children from playing and coming into contact with mercury vapor, which is toxic.
4. After indoor disinfection, open windows for ventilation.
5. Ultraviolet rays can cause burns to the eyes and skin, causing people and animals to leave the scene within 10 seconds.
6. It only works on specific viruses, microorganisms, bacteria, and has no effect on organisms such as insects, cockroaches, and fleas.
The Germicidal lamp emits light through ultraviolet light to achieve germicidal effect. Its emission spectrum is invisible to the naked eye, with wavelengths mainly ranging from 270nm to 280nm.
The Germicidal lamp does not need to be converted into visible light. The wavelength of 270nm-280nm can play a very good role in sterilization. This is because there is a rule for the absorption spectrum of light waves by cells. Ultraviolet rays at 265nm-285nm have the maximum absorption. The absorbed ultraviolet rays actually act on the Genetic material of cells, namely DNA. It plays a photochemical role. The energy of ultraviolet photons is absorbed by the base pairs in DNA, causing the variation of Genetic material, Make bacteria die immediately or unable to reproduce, achieving the goal of sterilization.
Ultraviolet disinfection has a wide range of uses, such as hospitals, schools, nurseries, cinemas, buses, offices, hotels and families. It can purify the air, eliminate the musty smell, and produce a certain amount of negative oxygen ions. The air in rooms disinfected by ultraviolet radiation is particularly fresh. In public places, ultraviolet disinfection can prevent some bacteria from spreading through the air or surface of objects.
