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. UV lamps at 172 nm deliver electromagnetic energy to alter organic molecule bonds to improve adhesion and UV curing applications without altering physical surface properties. 

Excimer Lamps for Ozone Production at 185 nm

Ultraviolet lamps designed to emit UV radiation in the range of 185 nm are known to produce ozone and effective oxidizer and deodorizer. Ozone lamps are commonly used in water and air sterilization systems to purify the air and eliminate the threat of airborne diseases while also removing foul odors.

LightSources offers a wide range of ultraviolet lamp solutions for many industries and applications, including UV sterilization, UV curing, and ozone production. We offer custom design, engineering, and manufacturing, including prototype development focusing on OEM-oriented solutions.

Does Ultraviolet Light Reduce TOC’s?

Total Organic Carbon, TOC, refers to organic carbon compounds found in water and may include man-made compounds, natural or altered product, or synthetic material. TOCs may contain bacteria and harmful materials or pathogens that could cause damage, system failure or health consequences if not effectively removed. Identifying and measuring concentration of TOC’s and water and practicing TOC reduction methods protects consumers, the environment, and many industries.

Removal of TOCs is critical in many applications where high-purity water is important for process quality. TOC reduction is important in: 

• Pharmaceutical industry processes

• Wastewater treatment

• Food and beverage industry

• Semiconductor and microelectronics production 

The impact of TOCs such as bacteria and other organic compounds can have serious negative effects on these processes and others. 

How UV Lamps Reduce TOCs

Ultraviolet, UV, lamps have been used for more than 100 years to eliminate harmful viruses and bacteria in many disinfection applications.  UVC lamps effectively kill microorganisms on surfaces, in the air and in water. UV lamps for TOC reduction remove harmful TOCs from water sources for many applications. 

Some TOC removal lamps utilize 185 nanometer (nm) emissions to produce ozone, which is a powerful oxidizer. Ozone lamps leads to oxidation of the total organic compounds which is the chemical reaction caused by 185 nm UV lamps.  TOCs are ionized by UV lamps and are then removed by a deionization process. 

Benefits of UV Lamps for TOC Reduction

UV lamps for TOC reduction provide many benefits in addition to delivering an effective, safe and reliable method to purify water.  UV lamps which are designed to emit wavelengths in the 254 nm range are the most effective germicidal lamps, and also remove viruses, bacteria, mold and other harmful pathogens including TOCs.  UV lamps for TOC reduction provide:

• Germicidal efficacy

• Low maintenance costs

• Low operational costs

• Can be used in air, water, and surfaces indoors or outdoors

• Produce no harmful byproducts such as with chemicals 

LightSources is a leading global supplier of UV lamps for germicidal applications in air, water, and surfaces. We provide high-quality, high-tech UVC germicidal lamps and UV lamps for TOC reduction.  Contact us to learn more about our UV germicidal lamps and TOC removal. 

UV Efficiencies in AC Units

Almost everyone enjoys the refreshing comfort of an AC unit in their home, commercial or industrial location during the heat of summer. But along with that comfort come microorganisms, mold, and mildew inherent in the passageways of an AC system. These unwanted intruders make the system work harder and shorten the mechanisms’ operating life.

AC Units: Breeding Ground for Pathogens

They can also cause a variety of ailments, including colds, allergies, COPD, bronchitis, asthma, headaches, and nausea. More serious illnesses include lung infections, pulmonary disease, autoimmune deficiency, and even cancer. This can cause serious long-term health consequences, even for those with no other underlying health conditions.

No amount of human labor, even by a licensed professional, can eliminate all the microorganisms and spores that collect in the vents, coils, and drain pans, and along the other interior surfaces of an AC system. Even the highest-quality HEPA filter cannot trap all the potentially toxic microscopic pathogens and volatile organic compounds (VOCs) that escape the AC system. The application of chemicals will only dispel toxins into the same area the AC blower system is intended to service.

UV Light Prevents Build-Up and Improves Efficiency

The answer is to install, with a new AC unit or as a retrofitted adjunct to an existing unit, a UV light sterilization system, particularly with light in the frequency of 253.7 nanometers (commonly referred to as 254 nm). UV light at that pinpointed frequency will instantly destroy the nucleus of each microorganism that passes through its radiation. Such UV light purification systems will work with optimum efficiency at temperatures ranging from 40° to 120° F, can be programmed to radiate 24/7 or only in tandem with the AC blower, and are virtually maintenance free, with bulbs lasting several thousand hours.

The UV in-duct version of AC purification systems should be mounted near and downstream from the system’s coil and should be aimed at the coil and condensation pan. The efficiencies gained from installing a UV germicidal AC purification system are many and varied. Families will be healthier, with less time spent taking the kids to the doctor. Workforces will operate more efficiently with greater productivity and decreased absenteeism.

LightSources is a leading global supplier of high-quality UV germicidal lamps to suit HVAC sterilization needs.  We design, engineer and manufacture high-tech germicidal lamps to meet various disinfection system needs and OEM specifications. Contact us to learn more about our many options for UVC germicidal lamps.

Keeping Food Safe with UV Light

In the food growing, processing, and service industries, a lot of things can go wrong. Dangerous contaminants lurk around seemingly every corner during each step of the process of bringing food from the field to the table. As a result, the agricultural, food processing, and restaurant businesses are subject to some of the most stringent regulations, resulting in increased costs, both to producers and consumers.

UV light food sterilization equipment can play an indispensable part as a silent partner in keeping food safe and of optimal quality for human consumption. UV light can be used to destroy harmful microbes, viruses, and other microorganisms that can threaten to shut down a business, temporarily or permanently, through substantial government fines, product recalls, costly litigation, and their resultant bad publicity.

UV Food Sterilization Keeps Food Fresher Longer

Properly installed and operated, UV light food sterilization systems can effectively and efficiently ensure that food and beverage products are free from the harmful microorganisms that human effort alone cannot begin to adequately combat. The result is a safer end product that stays fresher longer, increasing shelf life and preventing premature sprouting of foods like potatoes and onions.

Products during processing are invariably exposed to the air and various surfaces within the sphere of operation. UV germicidal lamps can continuously sterilize such air and surfaces, along with any water used for rinsing products or included as an ingredient in the production process. Surfaces may include everything from tables to slicers and grinders to pans, bottles, and conveyor belts, to the final packaging material, all of which can be constantly sanitized by UV light.

UV light sterilization systems are relatively low cost and very low maintenance, and eliminate the need for chemicals, herbicides, and pesticides. Examples of food industries efficiently and effectively benefited by UV light sterilization systems are beef, fish, and poultry producers; dairy and cheesemakers; beverage companies; liquid sweetener manufacturers, such as corn syrup; frozen food companies; bakeries (where UV light was first used to treat flour and yeast to eliminate insects); fruit and vegetable producers; and chocolatiers.

LightSources is a leading supplier of UVC germicidal lamps, found in air, surface, and water sterilization applications around the globe. We offer a wide selection of UV lamps and equipment to meet the needs of any surface, water or air sterilization system.  Contact us to speak with an engineer about our high-tech UV germicidal lamps.

UV Light Prevents Grease Build Up in Kitchen Exhaust

 Kitchen hood exhaust systems in commercial kitchens serve a very important purpose, to pull grease particles up and away through mechanical filters.  Kitchen exhaust systems vent excess heat above kitchen stoves and extract grease particles, leaving smaller particulates that may linger in the hood exhaust system.  These kitchen exhaust systems can encounter grease build-up in the vents if they are not cleaned regularly or treated with UV light sterilization solutions. 

How Does UV Light Help Kitchen Hood Exhausts?

Ultraviolet (UV) light emits UV radiation, electromagnetic energy, and is harnessed in UV germicidal lamps used in a vast range of applications.  UV light is used to purify the air, disinfect water and sterilize surfaces.  Utilizing UV light in kitchen hood exhaust systems provides many benefits beyond sterilization.  Kitchen hood UV exhaust systems can actually prevent grease build-up in the exhaust duct work.  

UVC lamps break down grease through photolysis and ozonolysis. UV light causes a photochemical reaction, breaking down the molecular bond while ozonolysis oxidizes the grease molecules. By breaking down the grease particles, they are converted into particles that are much easier to clean and do not build-up grease in the kitchen hood.  

This brings many benefits to restaurant owners by mitigating the risk of a grease fire, which can often occur with grease build-up in the exhaust hood.  UV kitchen exhaust systems also help kitchens to meet stringent health department code regulations by helping to keep the kitchen cleaner.  This provides a better work environment for employees and helps to maintain health standards for patrons. 

UV Lamps are Key to Successful UV Sterilization Systems

Using the right UV lamps for your UV kitchen exhaust sterilization system is key to successful prevention of grease build-up and sterilization.  UV germicidal lamps designed to emit 254 nanometer (nm) are effective in sterilizing air and surfaces.  Ozone producing lamps emit UV energy at 185 nm and are commonly used in air and water disinfection applications, deodorizing the air and reaching places that standard UV radiation cannot reach. 

When searching for the best UV lamps for your sterilization application, contact an experienced UV lamp manufacturer like LightSources. 

LightSources leads the industry in UVC germicidal lamp production, with a wide range of low-pressure, amalgam and many other lamp types designed with proprietary technology.  We provide high-quality UVC lamps proven to outlast and outperform comparable lamps of the same size.  Contact us to learn more and for custom lamp requirements for your UV germicidal application.

Indoor Air Protection with UV Sterilization Lamps

Indoor air quality (IAQ) is an important consideration related to the comfort and health of building occupants. IAQ is affected by the quality of air in and around buildings with airborne contaminants existing both inside and outside. Controlling pollutants inside will help to reduce risk and improve the quality of indoor air for greater health and well-being. 

Airborne contaminants that exist both inside and outside of buildings include:

• Indoor pollutants:

• Wood burning stoves

• Tobacco smoke

• Cooking

• Ozone and chemical emissions from cleaning solvents, electronic equipment and human metabolic byproducts

• Outdoor pollutants:

• Agricultural and farming

• Vehicle exhaust

• Waste management facilities

• Chemical storage areas

• Processing equipment emissions

• Combustion byproducts during manufacturing

UV Air Purifier in HVAC Systems

HVAC systems can be a great source of air pollution if dirt accumulates in the ventilation system. Dirt combined with moisture and poor management of condensation can create serious air quality problems due to biological growth. This typically occurs due to problems with the cooling coil condensation, humidifiers and other sources of moisture, poor maintenance of filters and inadequate particle filtration.

Air contaminants may be either biological, gaseous or particulate. Methods of improving air quality include eliminating the source of emissions, capturing emissions at the source with exhaust, dilution, increased ventilation, filtration and air sterilization. Of these methods, the only one that actually eliminates biological contaminants is air sterilization. HEPA filters effectively filter particles as small as .3 microns, although they are ineffective against volatile organic compounds (VOCs) present on a molecular scale.

UV air sterilization is proven to eliminate VOCs and microorganisms such as bacteria, viruses, mold and fungal spores and many other air contaminants. In-duct UV air purification systems installed near the cooling coils of HVAC units prevent microbial growth on cooling coils, thus preventing the spread of these contaminants throughout the home, office or building.

UV light is divided into UVA, UVB and UVC wavelengths, measured in nanometers (nm).  UVC radiation emitted at the wavelength of 254 nm is proven to instantly eradicate viruses, bacteria, fungi, mold spores, mildew and harmful microorganisms naked to the human eye.

UVC radiation penetrates the DNA of these living cells and renders them unable to replicate which instantly makes them harmless.  UVC lamps which are specially designed to emit UV radiation precisely at 254 nm effectively eliminate these harmful threats in water, air and on surfaces instantly upon exposure.  UVC ozone lamps emit wavelengths at 185 nm to produce ozone which is a proven oxidizer, sanitizer and deodorizer to eliminate foul odors from the air.

How Do UVC Lamps Work?

UVC germicidal lamps are commonly low-pressure Mercury lamps designed to emit the optimum UV radiation and wavelength for the germicidal application. The low-pressure lamps produce a Mercury arc and are engineered to radiate exactly 254 nm of UVC radiation.  UVC germicidal lamps contain a blend of Argon and Neon gases designed for the application.
UVC lamps operate with a discharge device comparable to fluorescent lamps, with the lamp body commonly constructed of:

• VH Glass – pure fused quartz that transmits both 185nm and 254nm
• L Glass – this is soft glass and designed to emit wavelengths at 254nm
• L Glass – quartz and Titanium which blocks out 185nm

UVC germicidal lamps are designed without the phosphor coating on the inside of the glass lamp to allow for the maximum amount of UV radiation to pass through the lamp. UVC lamps are designed with lamp ballasts which determine the amount of voltage required based on the rare gases used the lamp ballasts are a critical component of UVC lamp construction which deliver the optimum voltage.

UV Technology Provides Effective Ballast Water Treatment

New requirements under the Ballast Water Treatment Convention took place last September of 2017 with all ships required to have effective treatment systems on board.  When ships are transporting freight through international waters, they must use ballast water to balance their vessel by picking up water in one port when low on freight and discharging in another port when picking up freight.  This use of ballast water has been identified as one of the greatest threats to the world's oceans. 

When ships pick up sea water they also pick up all the ocean life with it which includes microorganisms, viruses and bacteria.  The problem occurs when this water is released into a new, foreign environment which may not be prepared to control the new invading species.  Cases of invading mussels have practically shut down dams and ports when multiplying and attaching themselves to structures, invading jellyfish have all but destroyed fishing industries making ghost towns out of once thriving fishing ports.

Due to these very real threats which jeopardize the sustainability of the planet’s oceans, the Marine Environment Protection Committee (MEPC) which is a subsidiary of the International Maritime Organization (IMO) began enforcing new standards for ships’ treatment of ballast water which must meet U.S. Coast Guard approval.
