It is also useful to use ultraviolet lamps for disinfection, but everyone should try not to use them too frequently during disinfection. It can be used once a week. If the home is relatively clean, there is no need to use ultraviolet lamps for disinfection all the time.
When using ultraviolet disinfection, people must stay away. Ultraviolet rays still have certain damage to human skin, which can easily lead to itching or allergies on human skin. , Although it is more convenient to use ultraviolet lamps to sterilize, but you still need to pay more attention to the use.
Ultraviolet lamp disinfection is of course effective. In addition to spraying alcohol, ultraviolet lamps are also used for disinfection in hospitals. If there is no disinfection effect, the hospital will not use this.
This UV lamp can also be used at home, but it is best not to stay next to the lamp when using it. For example, you can place the UV lamp in the room during the day. Of course, the door of the room needs to be closed, and people do not need to touch it directly. At present, there are many brands of UV lamps on the market. It is best to choose UV lamps produced by professional UV manufacturers, such as Ningbo Youwei Optoelectronics.
Of course, it is useful. Now many families in our country use ultraviolet lamps to disinfect all spaces in the home. However, when using this kind of lamps for disinfection, we must ensure that there is no one in the disinfection space, because ultraviolet lamps are harmful to the human body. It is especially harmful to people's eyes and skin. After a long time of irradiation, people's skin will appear red and swollen, and it will also induce cancer.
In addition to being used for disinfection in ordinary households, UV lamps can also be used in schools, hospitals, hotels, pet stores, factories, restaurants and other spaces.
Ningbo Youwei Optoelectronics is a professional manufacturer of high-quality ultraviolet germicidal lamp series products in China. The quality is reliable and the price is favorable. You can choose it once and use it for many years. You will not regret it.
UVC light can effectively kill SARS-CoV-2, the new coronavirus that causes COVID-19. Much of the research on this topic focuses on far-UVC light. This is a type of UVC light that still kills germs but is less harmful to humans.
UVC light is mainly used for disinfection in healthcare settings. While you can buy a UVC light lamp for your home, remember that these lamps are often lower in intensity.
Also, the optimal length of exposure, wavelength, and dose of UVC light needed for killing the new coronavirus is yet to be determined.
UV disinfection lamp for day or night use
Ultraviolet disinfection lamps can be used during the day and at night, but be careful to avoid light when using them. Because some bacteria in the air rely on the ""photoreactivation enzyme"" in the body to obtain energy, that is, repair damaged DNA through light, if the ultraviolet disinfection lamp is not protected from light, the damaged cells will restore normal vitality under visible light, called photoresurrection. Therefore, try to choose to use ultraviolet disinfection lamps at night. If it is during the day, you can draw the curtains to keep the light dim.
How to use UV disinfection lamp:
1. Air disinfection: When using, the doors and windows should be closed, and the room should be kept dry, and then the disinfection lamp should be turned on. The disinfection distance should not exceed 2 meters, and the disinfection time should be 30-40 minutes each time. If the light needs to be turned on again after turning off, it should be turned on again after 3-4 minutes. When the ultraviolet disinfection lamp is irradiated, it is strictly forbidden for personnel to enter the room, and the window should be opened for ventilation after the disinfection lamp is used.
2. Disinfection of the surface of items: spread out or hang the items to make them fully exposed to direct irradiation. When in use, the irradiation time of ultraviolet rays should not be less than 30 minutes, and the high-intensity, low-ozone ultraviolet germicidal lamps The irradiation time is preferably 30 to 60 minutes.
Precautions for UV disinfection lamps:
1. Ultraviolet rays have certain damage to human skin and mucous membranes. When using ultraviolet germicidal lamps, you should pay attention to protection. You must never look directly at the ultraviolet light source, otherwise your eyes will be hurt.
2. Ensure that the disinfection method is correct. When used for air disinfection, the disinfection distance should not exceed 2 meters, and each disinfection time is 30-40 minutes. When used for disinfection of articles, the irradiation time shall not be less than 30 minutes.
3. The surface of the ultraviolet germicidal lamp tube should be kept clean and free of dust, wiped with a 95% ethanol cotton ball once a week, and it is best to keep a record.
4. When disinfecting articles with ultraviolet rays, the irradiated surface should be directly irradiated with ultraviolet rays, and a sufficient irradiation dose should be achieved. When irradiating the air, all cabinet doors and drawers should be opened to ensure that all spaces are irradiated with ultraviolet rays, and disinfection should be as free as possible.
5. Because the service life of the ordinary ultraviolet germicidal lamp is 1000-3000 hours, it is necessary to make a record every time the ultraviolet germicidal lamp is used. In addition, the ultraviolet intensity of the ultraviolet germicidal lamp should be checked regularly with the ultraviolet intensity command card.
However, the UV lamps produced by Ningbo Youwei Optoelectronics have a lifespan of 8,000-10,000 hours, so there is no need to worry about their lifespan, and they can basically be used for more than 10 years at home. The light decay rate is also very low, almost negligible.
Choosing a high-quality UV lamp is equal to a lot less trouble. One choice, accompany for 10 years!
