Tanning and Skin Treatment
By now we know that there are 3 different cases of UV light: UV-A and UV-B light cause sunburns and premature skin aging, and exposure to both is associated with the development of skin cancer. UV-C light, which has the most energy of all three types, is the most harmful, but it fortunately doesn’t reach the Earth’s surface because our atmosphere absorbs it. UV light with the longest wavelength, and the least harmful. It is more commonly known as “black light”, and many use its ability to cause objects to emit fluorescence (a colored glowing effect) in artistic and celebratory designs. Many insects and birds can perceive this type of UV radiation visually.
UV lamps can be used to inspect various materials and surfaces. Materials react in different ways when they are exposed to the UV light. Some substances absorb the UV light’s energy and change it into visible light. It is called fluorescence. In the photo below you can see the florescent light picking up some substance/bacteria that was left after the object was lifted from the table.
Disinfection and Germ Control
UV light is widely used in water treatment facilities. This method of treating water is a lot more efficient than boiling water. The UV light can also get rid of chlorine and chloramine from water. Another use of the UV lamp is that it used in killing germs that are found in equipment, utensils, worktops, etc. This technique of germ control is used in the commercial businesses as well. It helps to avoid cross contamination or food poisoning. The UV light can also be used to increase the shelf life of vegetables and fruits.
Air Purification and Bug Eradication
The UV-C light, who’s wavelength is in the 280 to 100 nm range, is used for air purification. This UV light can kill mold, mildew, germs, viruses, and bacteria that float in the air. You can use an air purifier that has the UV-C light technology. There are products that clean the air and then there are products that clean the surfaces, Unfortunately, the products that clean surfaces admit a light that is harmful to humans and animals when in the same room so these products can only be turned on when no one else is in the room. These products would be great for schools, churches, office buildings, or any space that is not occupied 24 hours of the day. It would be a great way to clean spaces while people are away or sleeping. Potential cleaning costs could be reduced due to not having to clean the space as frequently, the lights could do most of the disinfecting work.
Many of the UVC products come with their own controls where you can then program when you would like them to be on. The surface cleaning UVC lights would pair well with a programmable timer where you can schedule when you would like the lights to kick on or off. Considering the safety risk of most of the UVC products, programmable timers are highly recommended to reduce the risk of someone coming in contact with the lights.
Due to research and innovation, the UV lamp can now be used in a number of different ways that are beneficial to people. It can help users in our daily lives. It has many commercial and industrial applications as well. It is used for treating water, purifying air, tanning, treating skin diseases, indoor gardening, eradicating bugs, identifying things, etc. In future, the scientists will be able to come up with more uses of UV lamps.
