UVC Lamp Uses and Options
Design and Engineering of UVC Lamps
UVC lamps are ultraviolet (UV) lights designed to produce UV light at a certain wavelength, denoted by the unit nanometer (nm). UVA, UVB, and UVC are the three main electromagnetic radiation bands that make up ultraviolet light. Unlike UVA (315-400 nm) and UVB (280-315 nm) radiation, UVC light has shorter wavelengths and is produced in the range of 100 to 280 nm.
The ozone layer entirely absorbs UVC radiation, and the bulk of UV light that is released by the sun that reaches the Earth's surface is in the UVA range. Manufacturers of germicidal UVC lamps develop, create, and produce UVC lamps that emit electromagnetic radiation at a certain wavelength to satisfy application requirements.
Applications for Germicidal UVC Lamps
It has been demonstrated that UVC light has very potent germicidal characteristics that destroy a wide variety of bacteria and viruses as well as inhibit the growth of mould and mildew. As a result, UVC lamps play a crucial role in several kinds of disinfection and sterilisation systems used in domestic, industrial, and commercial settings.
UVC Lamps to Purify the Air
In virtually every situation, UVC lamps are utilised in UV air sterilisation systems to enhance indoor air quality and stop the spread of dangerous airborne pathogens. People's health is safeguarded by UV air sterilisation systems in a variety of settings, including residential dwellings, hospitals, clinics, schools, dining establishments, public transit systems, and more.
Surface-Sterilization UVC Lamps
A lot of UV surface sterilisation systems use UVC lamp technology to stop the growth of dangerous microorganisms in locations like labs and commercial kitchens. UVC lights are frequently used to sterilise medical equipment and safeguard patients in operating rooms and hospitals.
UVC Lamps to Disinfect Water
Many water disinfection applications employ UVC lamp technology, which offers safe and effective germicidal efficiency. It has been demonstrated that UVC lamps may kill hazardous bacteria like Giardia and Cryptosporidium that chlorine cannot. Compared to using only chemicals, germicidal UVC lamps for water disinfection provide several benefits.
Types of UVC Lamps
185 nm UVC Ozone Lamps
Ozone, a powerful sanitizer and deodorizer, is created by UVC radiation in the 185 nm range. Numerous air and water filtration systems employ ozone lamps. The benefit of creating UVC radiation from ozone lamps for air cleaning is that its germicidal effects do not require direct line-of-sight exposure. Ozone is good in removing volatile organic compounds (VOCs) and unpleasant odours from the air because it can penetrate areas where other UVC lights cannot.
UVC Disinfection Lamps, 254 nm
The most prevalent UVC germicidal lamps used in a range of disinfection systems, including air, surface, and water, produce light with a wavelength of 254 nanometers (nm). Many bacteria and viruses are promptly destroyed by UVC light at 254 nm because it enters the cells and changes the DNA to stop cell multiplication. Numerous viruses and bacteria can be destroyed by UVC light with a wavelength of 254 nm, however the suitable UVC lamp must be used at the optimum dose to fulfil the needs of certain pathogens. Numerous viruses, including SARS-CoV-2, the virus that causes COVID-19, and several antibiotic-resistant superbugs have been shown to be destroyed by UVC radiation.
The kind of microbe, the intensity of the UVC lamp, and the length of exposure all affect how quickly different types of bacteria and viruses are killed.
Excimer Lamps at 222 nm
Far UVC, also known as UVC in the vicinity of 222 nm, is gaining popularity for several germicidal applications. Although they can be safer for human exposure under the correct circumstances, far UVC lamps have been shown to exhibit many comparable sterilisation qualities as 254 nm lights.
