Ultraviolet sterilization lamp - legendary sterilization expert

At present, there are a lot of ultraviolet sterilization lamp in the market, we may not be particularly aware of ultraviolet sterilization lamp, now we do not introduce, it is actually a kind of low-pressure mercury lamp. Low-pressure mercury lamps emit UV Light by being activated at lower mercury vapor pressures (<10-2Pa). There are two main spectral lines: one is the wavelength of 253.7nm; The other is the 185nm wavelength, both of which are uv rays invisible to the naked eye.

Working principle of ultraviolet sterilization lamp:

Ultraviolet sterilization lamp and fluorescent lamp luminescence principle is the same, the mercury atoms in the lamp tube are aroused to attack the characteristic spectrum line of mercury, low pressure mercury vapor first attack 254nm and 185nm ultraviolet ray, sterilization lamp tube is made of through violet glass or quartz glass, make the ULTRAVIOLET ray through the lamp tube transmission out.

The 254-nm wavelength of ULTRAVIOLET light is simply absorbed by the object, and the effect is on the DNA of the genetic material of the organism, which is damaged and causes the death of bacteria.

Ultraviolet radiation of 185nm wavelength and air can attack ozone with strong oxidizing effect, which can be used to kill bacteria. In addition, ultraviolet radiation can be combined with high intensity to kill bacteria and viruses in a short time.

Common USES:

Ultraviolet disinfection sterilization USES are very wide, hospital, school, nursery, cinema, bus, office, family, etc., it can purify the air, eliminate the musty smell, in addition also can produce a certain amount of negative oxygen ion.

The air in a room sterilized by ULTRAVIOLET rays is particularly fresh. Ultraviolet disinfection in public places can prevent some germs from spreading through the air or through surfaces.

But improper use, may also produce certain harm to the human body.

A moderate amount of ULTRAVIOLET light is beneficial to human health. But exposure to too much UV can be harmful, especially to the eyes. When ultraviolet ray irradiate skin, can cause hemal dilate, appear erythma, excessive irradiate can produce diffuse erythma, can form vesicle and oedema,
