The wavelengths of ultraviolet (UV) radiation, a kind of electromagnetic radiation with shorter than visible light but longer than x-rays, are what ultra violet lights are made to emit.
What exactly are UV lights?
The ultraviolet (UV) wavelengths from the sun, which are commonly broken down into three main subcategories, are mimicked by ultra violet lights. With respect to the three main bands of ultra violet illumination, UV wavelengths are measured in nanometers (nm).
Long-wavelength UVA, 315 to 400 nm, not absorbed by the ozone layer
UVB photons are medium wave, 280 to 315 nm in wavelength, and the ozone layer absorbs 95% of them.
The ozone layer absorbs all UVC rays between 100 and 280 nm.
For many UVC germicidal uses, far UVC light refers to ultra violet wavelengths in the region of 200 to 230 nm, especially 222 nm.
The ozone layer absorbs all of the sun's short-wave UVC radiation and around 95% of its UVB rays. In addition to being the primary cause of sunburns and skin cancer, which is the most prevalent type of cancer in the U.S., UVB light exposure raises the risk of cellular damage to living things.
But for the majority of terrestrial animals, including humans, UVB radiation also serves as the principal source of vitamin D. Calcium absorption and bone growth are both aided by vitamin D. There are pros and cons of using ultraviolet lights. Medical phototherapy uses for UVB and UVA lamps include the treatment of skin problems, mental health issues, and other ailments.
All of the sun's UVA rays that reach the earth's surface are the primary contributors to suntans and skin ageing, including wrinkles. The skin's elastin and collagen are harmed by UVA, which also produces free radicals. The primary types of lights used in tanning beds are UVA lamps.
Ultra Violet Germicidal Lights
UVC germicidal lamps should only be used in vacant locations since UVC light exposure is equally bad for human skin and eyes. However, far UVC lamps are gaining popularity since they have excellent germicidal characteristics, are safe for human exposure, and may be used to sterilise occupied rooms.
Wide-ranging germicidal applications employ UVC ultra violet lights, which have been shown to get rid of dangerous diseases and microorganisms in the air, water, and on surfaces. The use of UVC ultra violet lights in UV air purification systems eliminates airborne infections. They may also be used in HVAC systems, such as furnaces and air conditioners, to prevent mould growth and sterilise equipment as well as the air that travels through the UVC wavelengths.
Many water sterilisation systems include UVC lamps, and UVC ultra violet illumination has the ability to eradicate some dangerous bacteria from water that chlorine cannot, including Giardia and Cryptosporidium. Additionally, UVC ultra violet lights are utilised for several surface sterilisation tasks in a variety of residential, commercial, and industrial settings, including medical facilities, research facilities, dining establishments, and food processing.
Applications for UV Lighting
The interaction of ultra violet light with organic molecules has several practical uses, including biological and chemical consequences. UVC While UV lamps are utilised in germicidal applications, they also serve a variety of businesses in useful ways.
UV lighting is used in several processes and applications, including:
1. Antimicrobial
2.Tanning
3. UV Curing
4. Lighting
5. Messages
6. Backlighting
7. Phototherapy in medicine
8. Specialised functions
It is essential to utilise high-quality ultraviolet lights for any application that calls for the usage of ultra violet illumination. Not all UV lamps are made equally, so speaking with a knowledgeable UV lamp manufacturer will help you get the right kind of lights for your application.
