UVC lamps can safely disinfect objects, surfaces and spaces.
Water, air, and some surfaces and spaces are difficult to clean. In these environments, UVC lamps can be used for disinfection. For example, UVC lamps and robots are used to disinfect water, surfaces in empty hospital rooms, and large vehicles such as buses.
UVC lamps can be used in empty spaces of rooms to inactivate airborne viruses and other microorganisms. The light is located in the upper part of the room and is at least 8 feet (2.4 meters) high. They can be angled horizontally or towards the ceiling instead of glowing on the floor. Using fans and lights ensures that the air in the lower part of the room moves to the upper part of the room and vice versa. This way, all the air in the room is exposed to UV light, so any floating bacteria are inactivated. UVC lamps can also be placed in air ducts to inactivate viruses and other bacteria in the air that move from one room to another.
It is important that the UVC lamps used in the room people are in do not shine into the room. High-intensity UVC light can damage eyes and skin in seconds." "What’s known about UVC light and the new coronavirus?
UVC light can be used to kill the new coronavirus, SARS-CoV-2. Let’s look at what the research has discovered about UVC light and this coronavirus so far.
UVC light for disinfecting liquids
A recent study in the American Journal of Infection Control (AJIC) investigated using UVC light to kill large amounts of the new coronavirus in liquid cultures.
The study found that UVC light exposure completely inactivated the virus in 9 minutes.
UVC light for disinfecting surfaces
Another study, also published in the AJIC, looked at using a specific type of UVC light to kill SARS-CoV-2 on laboratory surfaces. The study found that the UVC light reduced the live coronavirus by 99.7 percent in 30 seconds.
The type of UVC light used in this study is called far-UVC light, which is UVC light between the wavelengths of 207 and 222 nanometersTrusted Source.
Far-UVC light is still damaging to germs but is less of a hazard to your skin and eyes than other types of UVC light.
UVC light for disinfecting air
One studyTrusted Source, published in the journal Scientific Reports, explored using far-UVC light to kill two types of human coronaviruses in the air. These two coronaviruses, 229E and OC43, can cause the common cold in humans.
Based off their results with these viruses, researchers estimated that, when applied to current regulatory standards, far-UVC light could kill 99.9 percent of airborne coronaviruses in about 25 minutes. They believe that these findings would extend to SARS-CoV-2 as well.
SUMMARY
UVC light can effectively kill SARS-CoV-2 or other coronaviruses in liquids, on surfaces, or in the air. Due to the fact that it presents less of a health hazard, far-UVC may be a good option for disinfection.
" "Advantages of UV germicidal lamps:
Long service life: Provides a service life of more than 9000 hours.
High-intensity UV output: We use high-purity quartz glass pipes and mature manufacturing processes to keep the UV radiation intensity above the national standard.
Smaller UV light decay: UV light decay is only 20-25% during life.
Reliability and stability: Mature manufacturing process and quality management ensure our UV lamps have a reliable life and stable output.
Focusing on UV light source for ten years, creating value for corporate customers.
