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!
