UV Sterilizer lamp are widely used in hospital operating rooms and spaces that require a high degree of control over the environment and bacterial density. Some family bathrooms are also equipped with UV Sterilizer lamp for sterilization. In general, such relatively humid places will contain bacteria, and in areas with high reproduction rates, more or less UV germicidal lamps are used. However, as we all know, UV Sterilizer lamp can not only sterilize, but also harm the human body. The main manifestation is that excessive ultraviolet radiation will affect the human body.

In fact, as long as you master the disinfection time and use the ultraviolet germicidal lamp correctly, you can avoid its negative effects. The emission spectrum of the ultraviolet germicidal lamp is 254nm, and the 254nm ultraviolet germicidal lamp kills bacteria by irradiating the DNA of microorganisms. The use of UV germicidal lamps is related to the range of irradiation space, the hanging distance of UV germicidal lamps, and the wiping and cleaning of UV germicidal lamps in UV germicidal lamps.

1. The radiation space range of UV Sterilizer lamp:

Many users of UV Sterilizer lamp ignore the effective space range of ultraviolet radiation, and only consider and calculate the radiation surface area. In addition to the area factor for each disinfection, the space is high or low, and the total space range is large or small. When using a germicidal lamp, calculate the total For cubic space, use UV Sterilizer lamp of corresponding power. The effective sterilization space range of 30w UV Sterilizer lamp should be less than 30 cubic meters. It is generally believed that the power of UV Sterilizer lamp per cubic meter of space should be greater than 1-1.5w, and attention should be paid.

2. The hanging distance of the ultraviolet germicidal lamp:

When using the ultraviolet germicidal lamp, pay attention to the irradiation distance between the object to be sterilized and the ultraviolet germicidal lamp, that is, the height of the UV suspension, which is less than 2.5 meters, and the hanging height of the ultraviolet germicidal lamp is greater than 2.5 meters, or even more than 3 or 4 meters. The intensity of ultraviolet rays is almost inversely proportional to the irradiation distance. If the suspension is too high, it will inevitably affect the sterilization effect.

3. The problem of reducing the intensity of ultraviolet radiation:

The radiation intensity of UV Sterilizer lamp will gradually decrease with the prolongation of use time.
