The use of ultraviolet disinfection lamp:

At present, the ultraviolet disinfection lamp used in China has high irradiation intensity and farther disinfection and sterilization effect. When using, it must be used in an unmanned state to avoid long-term contact with human eyes and skin.

To avoid the harm of ultraviolet rays to human body, we should first avoid direct sunlight at noon in summer, try to avoid outdoor activities between 0: 00 am and 3: 00 pm in 165438+, and use sunscreen skin care products and protective articles such as sun hats, sunglasses and umbrellas when going out.

Secondly, sunbathing should be done step by step according to the individual's specific situation, and the starting time should be short, so as to gradually increase the tolerance to light, but it is best not to last more than 2 hours, and choose 9: 00 am ~1l or 4: 00 pm. It is also extremely important for sunbathers to take simple preventive measures, especially to protect their eyes.

Medical researchers have confirmed that more sunlight will increase the risk of cataract in eyes. If the daily sunshine time is 1 hour, the probability of cataract will increase by 10% within one year. Daily sun protection is also important. You should choose a better sunscreen according to your skin and usage, and update it every 2 to 3 years.

When ultraviolet rays are used to kill the virus, no one can be present, so as to avoid direct ultraviolet rays from hurting people's eyes and skin.

Ultraviolet rays are non-penetrating and spread in a straight line, and there are three major sterilization blind spots:

1, only the upper surface of the object (food) can be sterilized, but not the lower surface of the object;

2, when a plurality of objects overlap, the surfaces of the overlapped parts of the objects cannot be disinfected;

3, only the outer surface of the object can be sterilized, but not the inside of the object! In other words, places that cannot be irradiated by ultraviolet rays (invisible light) cannot play the role of sterilization and disinfection.

Because of the above characteristics, your disinfection lamp is inside the ceiling, that is to say, the disinfection lamp only kills bacteria inside the ceiling. Occasionally, some ultraviolet vents radiate outward, which greatly reduces the danger, so the harm to human body is much less than direct radiation.
