UV light air purifier systems are one of the most cost-effective and safest methods used to purify the air we breathe.  UV air purification systems are used in municipalities and industrial applications to remove harmful contaminants from the air and eliminate odors. UV light air purification helps industries in complying with strict regulations regarding air quality while offering many benefits over other air purification methods.

UV Light Air Purifier is Environmentally Friendly

UV light air purifiers are environmentally friendly as they do not require the use of harmful or toxic chemicals, yet they are extremely effective at disinfecting and purifying the air.  Since UV air purifiers operate without the use of chemicals, there is no need to purchase, store, or dispose of harmful chemicals or byproducts. In addition to clean air purification methods, UV air purifiers use energy-efficient UVC germicidal lamps, creating an even more environmentally friendly operation.  

UV light air purifiers are available in compact designs that make them simple to operate and easy to maintain.  With long-lasting UVC germicidal lamps, UV air purifiers save time and money with very little ongoing maintenance required.

UVC Radiation Offers Powerful Germicidal Effectiveness

UVC radiation is proven to quickly and effectively destroy airborne contaminants including bacteria, fungi, mold, viruses, and volatile organic compounds (VOCs).  By penetrating the nuclei of the harmful cells, UVC radiation immediately renders them harmless and unable to replicate. UV air purifiers operate with UVC germicidal lamps designed to emit specific wavelengths at 254 nanometers (nm), which is the most effective band of UVC radiation that instantly destroys the cells of harmful contaminants.

UV Light Air Purifiers Benefit Many Industrial Applications

UVC germicidal lamps help to prevent the spread of airborne illnesses in many residential and commercial settings.  UVC light air purifiers are utilized in many commercial buildings to provide safe and clean air for workers and visitors and are also becoming quite popular in more residential settings.  Healthcare facilities benefit from UV light air purifiers by providing clean air to patients who may already have a compromised immune system. Many facilities such as hospitals, doctors’ offices, nursing homes, and rehabilitation centers provide safe and clean air to patients with UV light air purification.

Many industrial applications are realizing the benefits of UV air purification to provide a safer workplace while meeting strict air quality codes and regulations.  UV air purifiers are used in many applications to eliminate toxic chemicals produced during certain applications such as plastic, rubber, or wood surfacing treatment processes.  Companies can reduce their output of harmful compounds while protecting their employees with cleaner and safer air.

UV air purification systems can be installed in new existing HVAC units to eliminate the spread of air pollutants including bacteria, viruses, parasites, dust mites, mold spores, and fungi.  UV air purifiers are easy to maintain and reduce the maintenance required to clean air ducts as the UVC radiation keeps coils clean while disinfecting the air. Make sure that you consult with a UVC germicidal specialist before purchasing your UV air purifier and UVC germicidal lamps.

Excimer Lamps: Many Uses Beyond Far UVC

Excimer lamps are ultraviolet lamps that are designed to emit UV wavelengths in the range of approximately 170 nanometers (nm) to 230 nm, dependent upon noble gas excimers present. Excimer lamps are useful in many applications, such as UVC sterilization, ozone generation, and UV curing processes.

What is an Excimer Lamp?

Excimer is a term that refers to a temporary atomic state where high-energy atoms create short-lived molecular pairs, or dimers, when electronically excited.

Excimer refers to a transient atomic state in which electronically excited high-energy atoms create short-lived molecular partners or dimers. UVC photons are released as excited dimers, excimers, return to their original state. The term excimer refers specifically to homodimeric bonds, a bond between the same species of molecules such as xenon (Xe). A xenon excimer lamp uses Xe atoms to form excited Xe2 dimers, which result in UV photons emitted at the 172 nm wavelength.

Heterodimeric bonds (bonds from two different structural species), has the official term of an exciplex. An example of an exciplex is the bond with Krypton-chloride (KrCl), which is an exciplex that emits wavelengths in the range of 222 nm. 222 nm UV light is recognized for high antimicrobial capabilities and is also referred to as Far UVC.

Excimer lamps are the generally accepted term for lamps that emit both excimer and exciplex radiation in the range of 172 nm and 222 nm, respectively.

How Do Excimer Lamps Work?

Excimer lamps irradiate the desired UV wavelength in the vacuum ultraviolet (VUV) range (between 100 – 200 nm) in a specialty coated, sealed quartz glass chamber with noble gases. An intense plasma discharge also called a dielectric barrier discharge, is generated from the high-energy electrons. The atomic excitement of noble gases is induced by the plasma, which triggers the creation of excited dimers, or excimers. The Excimer-specific UV radiation results during the final emission stage when Excimer molecules disassociate and return to their original state, all of this occurring in nanoseconds.

Excimer Lamp Application Uses

Excimer lamps are ideal in many applications and are gaining significant attention with the ability to disinfect surfaces with the same efficacy as traditional 254 nm UV lamps without the risk of human exposure.

Excimer Lamps for Sterilization, 222 nm

Excimer lamps designed to emit 222 nm radiation, also called Far UVC lamps, are increasing in use for sterilization applications worldwide with the same germicidal effectiveness as traditional 254 nm lamps and can be used in the presence of humans. In one study published at the National Library of Medicine, the effects of 222 nm UVC light for disinfection and healing effects were shown to be effective on methicillin-resistant Staphylococcus aureus infection in mouse wounds without damaging DNA.

Both 222 nm lamps and 254 conventional low-pressure mercury lamps were used in this study. 222 nm UVC light significantly reduced bacterial count on mice skin wounds infected with methicillin-resistant Staphylococcus aureus (MRSA). When compared with the effectiveness on days 3, 5, 8, and 12, irradiation of bacterial counts with 222 nm UV light was the same as or even more effective than 254 nm radiation.

Sterilization and Safety

While 254 nm UVC germicidal lamps have been used for decades and are highly effective at eliminating the risk of infection from many viruses, bacteria, and harmful pathogens, exposure to this wavelength is harmful to humans. 254 nm UV radiation causes DNA lesions such as cyclobutane pyrimidine dimers (CPD) in human cells. Long-term repeated exposure can cause skin cancer and eye damage.

Short wave, 222 nm UV light, is absorbed by the proteins in the membrane and therefore does not reach the nucleus of human cells. This same study evaluated the safety of 222 nm excimer lamps vs 254 nm conventional germicidal lamps and found that immediately after irradiation, the epidermis irradiated with 254 nm light showed the presence of CPD expressing cells but was not present after irradiation with 222 nm UVC. Excimer lamps emitting 222 nm light are proving to provide highly effective sterilization combined with human biological safety.

Excimer lamps have other uses in addition to sterilization, and not all Excimer lamps are far UVC lamps.

Excimer Lamps for Surface Activation, 172 nm

Alteration of surface energy is required in many industrial applications for surface treatments, such as applying coatings and adhesives to substrates. 172 nm lamps are an excellent choice for surface modification and provide additional benefits of cleaning and activating substrate surfaces simultaneously. 172 nm provides powerful electromagnetic energy to directly crack major bonds in organic molecules without altering any physical surface properties.

Excimer lamps designed to emit 172 nm increase the wettability and surface energy of various substrates such as glass, metals, and polymers. Surface energy is measured in millinewtons per metre (mN/m), with 172 nm excimer lamps meeting surface activation energy requirements for solvent inks, UV inks, water-based systems, and coatings. Excimer lamp technology provides many benefits to UV curing applications, including cleaning, bonding, and coating.

Surface Activation Alternative Treatment

172 nm Excimer lamps are a good alternative to plasma and Corona-based surface treatments with considerably less excess heat and reduced thermal load. Both plasma and Corona are electrical discharge surface activation methods. Excimer lamps
provide effective surface activation without damage to surface structure, resulting in better results for bonding.

Ozone Production with Excimer Lamps, 185 Nm

Excimer lamps are also effective at producing ozone, a natural oxidizer, odor reducer, and disinfectant effective in air and water sterilization applications. Ozone is typically produced at 185 nm standard low-pressure mercury lamps, although Excimer lamps filled with xenon are an efficient source to generate ozone with no nitrogen oxides (NOx) as the UV radiation is not high enough to excite nitrogen in the air.

Excimer lamps are proving to be a very exciting development and an increasingly promising offering in the UV lamp market.

LightSources is currently in the development of Excimer lamps, and we offer a wide selection of UVC germicidal lamps used in surface, water, and air sterilization systems worldwide. We design, engineer, and manufacture UVC germicidal lamps, UV curing lamps for surface treatment applications, as well as ozone-producing lamps.

Ultra Violet Lights: Types and Applications

Ultra violet lights are designed to emit ultraviolet radiation, a form of electromagnetic radiation, with wavelengths in the ultraviolet (UV) range, which is shorter than visible light, although longer than x-rays.

What are UltraViolet Lights?

Ultra violet lights are designed to mimic ultraviolet (UV) wavelengths from the sun, which are typically divided into three basic subcategories.  UV wavelengths are measured in nanometers (nm), with the following distinctions made for the three common bands of ultra violet lighting:

• UVA –  315 to 400 nm, long-wave, not absorbed by ozone layer

• UVB –  280 to 315 nm, medium wave, 95% of UVB rays are absorbed by the ozone layer

• UVC –  100 to 280 nm, all UVC rays are absorbed by the ozone layer

Far UVC light describes ultraviolet wavelengths in the range of 200 to 230 nm, specifically 222 nm, which is gaining interest for many UVC germicidal applications.

All short-wave UVC light and about 95% of UVB rays emitted by the sun are absorbed by the ozone layer. Exposure to UVB light increases the risk of cellular damage to living organisms and is the main cause of sunburns and is thought to be the main cause of skin cancer, the most common form of cancer in the U.S.

UVB light is also, however, the main source of vitamin D to most land vertebrates, including humans. Vit D assists with bone development and helps the body absorb calcium. Ultra violet lighting can be both harmful and beneficial to life. UVB and UVA lamps are also useful for a variety of medical phototherapy applications, such as treating skin conditions, mood disorders, and other health conditions.

All UVA light from the sun reaches the earth’s surface and is the main cause of suntan and skin aging, including wrinkles. UVA damages the skin’s elastin and collagen in the skin and generates free radicals. UVA lamps are the main types of lamps used in tanning beds.

UVC Germicidal Ultra Violet Lights

Exposure to UVC light is also harmful to human skin and eyes, and UVC germicidal lamps should be used in unoccupied spaces. Far UVC lights, however, are gaining recognition as providing highly effective germicidal properties while safer for human exposure and can be used for sterilization purposes in occupied spaces.

UVC ultra violet lights are used in a wide range of germicidal applications and are proven to eliminate harmful pathogens and microbes in the air, in water, and on surfaces. UVC ultra violet lights eliminate airborne pathogens in UV air purification systems and can be used in HVAC systems, including furnaces and AC units, to prevent mold buildup and sterilize equipment as well as the air that passes through the UVC wavelengths.

UVC lamps are also used in many water sterilization systems, and UVC ultra violet lighting can even kill some harmful bacteria in water that chlorine does not kill, such as Cryptosporidium and Giardia. UVC ultra violet lamps are also used for many surface sterilization applications such as in hospitals, laboratories, restaurants, food processing, and many other residential, commercial, and industrial applications.

Ultra Violet Lighting Applications

There are many practical applications, including biological and chemical effects, derived by the way that ultra violet lighting interacts with organic molecules. UVC Ultra violet lights are used in germicidal applications but ultra violet lights perform many valuable functions to many industries.

UV lights are found in many applications and processes such as:

• Germicidal

• Tanning

• UV Curing

• Illumination

• Signs

• Backlighting

• Medical phototherapy

• Specialty purposes

Whatever purpose is planned for the use of ultra violet lighting, it is critical to use quality ultra violet lamps. Not all UV lamps are created, and consulting with an experienced UV lamp manufacturer will help to ensure that you receive the correct type of lamps for your application.

UV light in the UVC range is known to provide powerful germ-killing properties for disinfection and sterilization in many environments. UVC germicidal lamps are used in many germ-killing applications, such as UV air purification, surface sterilization, and water disinfection.

UV lamps are very useful in food and beverage processing applications to prevent a variety of foodborne illnesses, protect against infestation from harmful pathogens, and preserve food keeping it fresher longer.

UV Food Irradiation FDA Approved

UV food irradiation has been approved by the US Food and Drug Administration, FDA,  for decades and is proven to be an entirely safe method to treat food products. UV food irradiation helps food processing plants to ensure foods are free from harmful diseases such as listeria, which can be found in raw foods and processed meats, vegetables, and dairy products. 

These foods can become contaminated after food processing, and using UV disinfection methods on food processing conveyor belts helps to keep contact surfaces sterile without using harsh chemicals. UV food irradiation helps to prevent listeria during final food packaging for many ready-to-eat foods.

UV Irradiation Protects Many Food Types

UV irradiation protects many types of foods and beverages, providing many benefits to food and beverage processors such as:

• Prevents insect infestation in grains, nuts, vegetables, or dried fruit

• Prevents potatoes, garlic, and onions from premature sprouting

• Prolongs freshness and extends shelf life, especially for bread and dairy products

Excimer Lamp Application And Uses

The term Excimer lamp refers to ultraviolet lamps that are specially designed to emit UV radiation in the wavelength range of 170 nm to approximately 230 nm. The wavelength emission depends on the noble gas excimers present in the lamp. Excimer lamps are popular for generating far UVC, typically in the specific range of 222 nm, an ideal range for UV disinfection, although they are capable of producing other ranges for use in applications. 

Excimer lamps designed to emit UV radiation in the range of 172 nm are commonly used for UV curing applications and when designed to emit 185 nm, are known to create ozone.

Excimer Lamps at 222 nm for Sterilization

Conventional UVC germicidal lamps typically emit radiation in the range of 254 nm, which is highly effective for germicidal applications, although is unsafe for use in the presence of humans. Far UVC at 222 nm is proven just as effective, if not more than 254 nm in some germicidal applications and offers the benefit of safe usage in occupied spaces. 222 nm Excimer lamps are proven just as effective at eliminating threats of stubborn viruses such as methicillin-resistant Staphylococcus aureus (MRSA) and other antibiotic-resistant pathogens.

UV Surface Activation at 172 nm with Excimer lamps 

UV Excimer lamps designed to emit 172 nm radiation are used primarily for UV curing and surface activation industrial applications. Ultraviolet radiation at 172 nm alters surface energy to allow for improved adhesion of coatings to substrates.

What Conditions Do Medical Phototherapy Lamps Treat?

Ultraviolet light has many useful purposes, with UV electromagnetic radiation providing germicidal and healing properties.  Medical phototherapy is the process of using various wavelengths of UV light to treat certain conditions. UV phototherapy lamps are useful in treating and providing relief to a variety of ailments and illnesses. 

Phototherapy lamps are proven to treat many health conditions, including:

Neonatal jaundice - UV lamps are the main source of treatment to break down bilirubin in the blood that occurs when an infant’s liver is not yet fully capable of breaking down the toxins in the body.  “Bili” lights help the baby’s body and prevent brain damage. 

Mood disorders, depression – many people experience Seasonal Affective Disorder (SAD) during the winter months with less sunlight. Light therapy lamps help to treat depression which can be mild to severe and can improve symptoms of fatigue, lack of interest, and many other depressive symptoms. 

Sleep disorders – phototherapy lamps treat sleep disorders, including jet lag, by helping the body to regulate the natural circadian rhythm. 

Light therapy lamps also treat a host of skin conditions and are prescribed by dermatologists to ensure the right wavelength is used to treat specific conditions such as: 

Acne – UV light is proven to help treat acne, which affects nearly 60 million people in the U.S. Topical treatments can minimize symptoms, but many are ineffective, leaving people looking for help. Combinations of red and blue light therapy have been proven successful in treating acne to reduce outbreaks and lessen the severity of symptoms. 

Eczema – UV light is useful for successfully treating eczema with UVA, UVB, and narrow-band UVB wavelengths that reduce symptoms and help to clear skin. 

Psoriasis – light therapy helps to treat psoriasis by successfully lessening the severity of symptoms and preventing outbreaks.  Sometimes medication called Psoralen is used in conjunction with UVA and UVB wavelengths to help absorption for successful treatment. 

Vitiligo – UV lights treat vitiligo which is a skin condition that leaves white patches on the skin due to a loss of melanin. Narrowband UVB lamps are a popular way to treat vitiligo and help repigment skin cells.

Ultraviolet medical phototherapy lights are used to treat these conditions and others, such as helping wounds to heal by increasing blood circulation and preventing infection. Photodynamic therapy, PDT, is a treatment where UV blue light is used in conjunction with medications to treat certain types of cancer and kill cancer cells or tumors of atypical growth. 

As you can see, ultraviolet lamps have vast healing power, although the right type of lamp with the correct wavelength must be used to treat each condition. It is important to use light therapy correctly under a physician’s care. 

LightSources is a leading global supplier of UV and fluorescent lamps using medical phototherapy as well as germicidal applications.
