Electromagnetic radiation with a wavelength shorter than visible light is known as ultraviolet (UV) light. UV light is divided into three groups based on its wavelength: UV-A, UV-B, and UV-C.
Ultraviolet light has important uses in many different industries, even though it is invisible to the human eye. With the creation of UV LED lights, these uses have grown even more. We'll talk about a few UV LED light applications today.
Ultraviolet Lights: What Are They?
An unseen type of electromagnetic energy, or light energy, ultraviolet (UV) light has a higher frequency and a greater energy content than visible light. UV light was once referred to as "chemical rays" when it was first discovered in the 19th century because it has the ability to alter some compounds at the molecular level.
There was no commercially available UV LED light until 2010. But as LED technology advances, UV LED lights have entered the market and started to be utilized in a number of sectors, including healthcare and cosmetics.
There are specific uses for each of the several UV light frequencies in other industries. For instance, UV-A is utilized for nail care, but UV-B and UV-C are used for medical light therapy and sterilizing.
Here are just a handful of the numerous uses for UV LED lights:
Curing in Industry and Cosmetics
The method of UV curing involves using UV light to "dry" or cure inks, coatings, adhesives, resins, and polymers so they harden without the need for heat.
In the past, unregulated UV lights were used to cure nail polish. Nevertheless, a possible risk of skin cancer was noted in a 2013 study that was published in the Journal of the American Academy of Dermatology. According to the study, LED lamps' reduced light frequency made them far safer for this use.
Flexfire LED's Ultraviolet LED Strip Lights are perfect for producing the lamps used in nail salons since they emit UV-A, which is just the kind of UV LED light for nails and safe for skin exposure.
Analytic Tools
The use of UV analysis lamps, which excite the electrons of substances under examination and cause them to glow, is another application for UV light that makes some compounds visible to the naked eye. The following are some materials and liquids that change color or emit fluorescence in response to ultraviolet light:
Invisible or security inks: These are used to verify the legitimacy of banknotes, identification documents, and credit cards. Under UV light, certain components in these inks glow.
Blood and bodily fluids: Certain bodily fluids, like perspiration and saliva, glow when exposed to ultraviolet light, which aids forensic investigators in finding evidence at crime scenes.
Materials and fibers: A lot of synthetic and natural fibers can glow when exposed to UV light, which makes it easier to spot remnants of clothes or fabric.
To aid identify theft or forgeries, special dyes and resins are used to brand precious items or documents that are only visible under ultraviolet light.
Field of Gemology
The ability to recognize and authenticate gems and minerals is made possible by ultraviolet (UV) light, which is a vital instrument in gemology.By monitoring the fluorescence that certain stones, like diamonds and rubies, emanate when exposed to ultraviolet light, experts may differentiate natural gems from manufactured or artificially treated ones.
It is also used by collectors to recognize and categorize fluorescent minerals that shine when exposed to ultraviolet light, such as fluorite and calcite.
Disinfection and Sterilization
UV-C radiation is used in the medical field and is a great option for purifying water and air. High radiation causes microorganisms like viruses and bacteria to lose their genetic material, which stops them from infecting people. UV radiation is used for this kind of disinfection in a variety of industries, including food processing and healthcare.
In fact, this is one of the reasons it's advised to dry clothes in the sun-natural UV radiation eliminates potentially dangerous bacteria on clothing in addition to avoiding energy-hungry dryers.
Indoor Gardening
When growing fruits, vegetables, and other plants for human consumption inside, UV LED lights are crucial. Polyphenols, which are thought to have anti-aging and antioxidant properties, are produced more frequently under UV LED lighting.
UV lights are useful for resin-producing plants, like medical marijuana, in addition to edible gardening because they boost the development of therapeutic compounds like terpenes and cannabinoids and increase the effectiveness of their medicinal effects.
Properties of Health
These days, UV phototherapy is used to treat vitiligo and psoriasis, as well as to stop the growth of a particular kind of skin cancer. When used in conjunction with other treatments, UV lamps helped many patients in the early stages of the disease achieve long-term remission, according to the American Cancer Society.
The immune system is suppressed and inflammatory reactions are decreased by UV light in psoriasis, an inflammatory skin disorder brought on by immune system dysfunction.
UV Light's Dangers
Unprotected ultraviolet (UV) light exposure can harm the skin and eyes in a number of ways, increasing the risk of skin cancer, sunburn, and premature aging.
But like our UV LED strips, "black lights," or UV lights used in nightclubs, emit UV-A radiation. Because this kind of UV-A has a longer wavelength and less energy than other types of UV, it cannot penetrate skin or harm it.
UV Light Applications' Significance in Daily Life
UV light has a wide range of uses, including forensic investigation, disinfection, and cosmetics and medicine. UV LED lights have applications in daily life, even though we have highlighted a few important purposes, such sterilization and skin care.
UV light is crucial for pest control, food preservation, dental care, and pool purification and treatment without the use of chemicals. These applications enhance productivity across a range of sectors and promote our health and welfare.
