UV Ink Curing Lamps

The process of UV ink curing has been around since the 1960’s and uses high intensity ultraviolet light to create a photochemical reaction. By using the proper intensity of UV wavelengths, a byproduct is produced that hardens resin and dries inks. It offers numerous advantages over traditional heat-cured systems and has become the method of choice for many as it safely and cost-efficiently cures inks, as well as adhesives, coatings, varnishes, decorative glazes and lacquers.

UV Curing Benefits

UV ink curing systems are easy to operate and maintain and more environmentally-friendly than traditional systems. Since UV ink curing does not produce noxious fumes as heat-cured inks, it does not require expensive exhaust systems to counteract the fumes. UV systems are used by industries such as automotive, electrical, industrial, and medical.

Another benefit of curing inks with UV light is that the ink dries instantaneously, which greatly speeds up production times as well as helps to improve the overall quality of the product. The speedy drying time means products are ready for shipment much quicker and the chance of dust or other airborne objects ruining the finished product is reduced.

UV Ink Curing Lamps

The types of UV lamps used for UV ink curing includes low pressure and medium pressure UV (MPUV) curing lamps as well as amalgam UV curing lamps. Using a wavelength of 254nm, UV low pressure lamps are used to cure inks in high-quality magazines and newspapers. In addition since low pressure lamps operate on much less power than MPUV lamps, they are ideal for applications requiring dimming.

MPUV lamps are the best choice for applications that require a higher intensity of UV light due to shorter exposure times and need high-speed press runs. Also there are some industries that prefer amalgam lamps for the efficient drying of inks and adhesives with a cationic base. Amalgam lamps produce outputs of 300 to 1000 watts, of which one-third is usable UVC energy, and offer the opportunity to downsize a system while still maintaining maximum efficiency for UV curing.

With the combined resources of LightSources in the U.S. and LightTech in Europe, we are global leaders in UV curing lamps as well as UV air treatment systems. We partner with OEMs of any size to design, engineer and mass-produce new types of proprietary and specialty lamps cost-effectively and with short turnaround.

UV Paint Curing

UV light produces a chemical reaction that is used in industrial applications such as UV paint curing, primers, fillers and clearcoats as well as inks and other types of coatings.  Much quicker and more efficient than traditional baking methods, UV paint curing systems also offer significant energy savings without producing any hazardous byproducts.  First introduced in the 1960’s, UV lamps have rapidly gained acceptance by a diverse range of industries and are now the preferred choice of many OEMs across the globe.

To instantly cure paints, and a variety of other coatings and finishes including lacquers, glazes and varnishes, high-intensity ultraviolet lamps are used to create a photochemical reaction.  On the other hand, conventional water and solvent based thermal drying methods work by solvent evaporation, which not only takes time but also creates polluting emissions.  With UV light systems’ instant curing, manufacturers report higher production rates, better bonding, no loss of volume and less likelihood of product damage as in slower drying methods.  Along with being environmentally friendly, UV lamps are also easy to operate and maintain.

UV Polymer Curing

UV Polymer curing is a process that uses UV light to alter the properties of a polymer, or photopolymer.  A photopolymer is the term for a polymer that responds to UV light, which is basically invisible electromagnetic radiation.  When a photopolymer, which can be a variety of resins, is exposed to the UV radiation, it will typically harden and seal, creating a strengthened surface or an unbreakable bond.

UV Polymer Curing Applications

UV Polymer curing is used in many industrial applications to instantly dry ink or to create a hardened surface without use of solvents or chemicals.  Some common examples of useful applications include:

• Adhesive Bonding

• Inks / Varnishes / Lacquers

• Decorative Glazes

• Coatings

• Label Printing

• Graphic Designs

• Disinfection of Medical Equipment

These are just a few of the many industries that are using UV lamps for curing various polymers.  There are many additional applications for UV curing, and more and more businesses are seeing the benefit of this process.  UV curing was first introduced in the 1960’s, and it is increasingly being adopted by companies as there are many advantages over prior methods of curing polymers.

Curing Lamps

There are three types of UV lamps used for UV polymer curing.  High Pressure UV (HPUV), Medium Pressure UV (MPUV), and Amalgam Lamps.  High Pressure (HPUV) curing lamps are also referred to as Metal Halide lamps, and use mercury with short wavelength outputs.  The HPUV lamps are typically used for the altering of polymers by hardening resins in many of the applications mentioned above.  Medium Pressure lamps (MPUV) are often used for water and air disinfection purposes, while Low Pressure Amalgam lamps are typically used for curing catatonic inks which are inks that are typically an epoxy based resin and respond to UV lighting.  LightSources and our European partner, LightTech, are proud to have pioneered new pellet technology for amalgam lamps.

There are so many benefits to using UV lights for curing it will be difficult to list them all.  We can begin with efficiency.  Imagine a conveyor belt full of parts passing under a UV light as they head to their next destination, possibly quality inspection or packaging.  While no one touched the parts, sprayed solvents on them, or even laid eyes upon them, they underwent a very important process.  Just by passing under the lights, the surface was hardened and strengthened, a strong scratch-resistance texture was enhanced, and any printing or graphic design needing reinforcement was just instantly dried and strengthened.

Now imagine a different manufacturer that does not use UV curing.  They must have an assembly line with people spraying solvents on the parts, requiring face masks and ventilation and still exposing the employees to harmful chemicals in the air and on the skin.  This also opens the door for human error, uneven coating, and inconsistency.

As you can clearly see from these two examples, the efficiency of UV curing is definitely one of the most valuable benefits.  This efficiency also leads to increased production speeds as several parts can be treated at once simply by passing under a row of the proper high intensity UV lighting.   Choosing to cure your parts with UV lighting will increase your output dramatically, while not requiring an investment in an increased labor force, workstation for an added process, or supplies of chemicals that are most likely harmful to the environment.

In addition to efficiency and cost savings, consistency is another big advantage of using UV curing over any other process.  With UV lighting, the amount of exposure is constant, and consistent.  There is no chance of human error in applying an outer coating unevenly on a large amount of parts.  This consistent process results in less quality issues such as internal rejects and the worst rejects of all, customer returns and complaints.   A consistent process is something that all quality minded OEM’s are searching for as consistency results in superior quality, time and again.

Efficiency and consistency are and should always be a top consideration for any production process, (both result in increased profits), but let’s not forget an even more important benefit – the health and safety of your workers and the environment.  Simply by using UV radiation to cure your parts, you are saving your employees from inhaling harmful chemicals, you are not emitting pollutants into the air, and you also do not have to worry about properly storing or disposing of such harmful chemicals.   Any chemical substance on a worksite must be handled with proper storage and disposal guidelines, while maintaining material safety data sheets on the chemical or solvent.

Not only does the increased efficiency and consistency provide an instant return on your investment and a quick increase to the bottom line, not purchasing, storing, disposing of or documenting alternative substances is also a huge savings, and instant increase in profitability.

With all of these benefits, it is difficult to imagine why a manufacturer would choose an alternative method over UV polymer curing.   Efficiency, consistency, safety, less regulations, increased profits, and last but not least – longevity.   LightSources UV curing bulbs will retain their energy output up to 90% of their end of life cycle, enhancing and prolonging all other financial benefits.  As we all know, time is money.  Less time spent processing parts, or replacing bulbs, is an immediate increased profit.

LightSources in the United States, and our European partner, LightTech, provide quality custom UV bulbs to OEM’s large and small all over the world.   If one of our standard sizes does not fit your application, contact us to see how we can assist you in providing custom built bulbs for your required process.   LightSources and LightTech are also the only manufacturer to offer universal installation.   Our lamps can be installed either horizontally or vertically while maintaining equal efficiency.  This feature is exceptionally critical when applying the UV polymer curing process to three dimensional parts, allowing an even exposure to the UV radiation reaching what were previously hidden dimensions.

UV Light Air Conditioner Benefits

Weighing the cost against the benefits, it is difficult to find a downside to installing a UV light air conditioner purification system in any commercial, industrial, municipal, medical, or residential building. UV germicidal light, specifically at the frequency of 253.7 nanometers (commonly referred to as 254 nm), effectively eliminates a host of pernicious microorganisms, such as fungi, bacteria, viruses, molds, spores, parasites, and dust mites.

The result is, at the very minimum, cleaner air for residents, employees, visitors, and others throughout the structure serviced by the air conditioner. In addition, UV germicidal lamps prevent build up on equipment which prolongs the useful life of air conditioning systems and enhances efficient operation.

UV Light AC System Proven to Reduce Fungi

UV light air conditioner purification systems provide many benefits and efficiencies. UV radiation is extremely effective at eliminating harmful pathogens that can collect on air conditioner units and spread through circulated air. In a recent scientific study evaluating the effectiveness of UV radiation to eliminate fungi in air handling units, a 286,000-square-foot office building in Oklahoma was equipped with a UV system on the main air handling units of two floors while two other floors had no lamps installed. Readings were taken from the study floor and the control floor to detect the concentration levels of mold and fungi since installation.

More than a dozen fungi species were present in May prior to installation of the UV system. When taken again in September, the readings on the floor with the UV system had decreased, while nearly every taxon increased its concentration on the control floor, in a couple of instances nearly 100-fold.

Health Benefits of UV Light for Air Conditioning Systems

UV lights in air handling units and air conditioner systems remove harmful pathogens from the units and from circulated air which provides significant health benefits. Some of the symptoms and ailments alleviated by the purified air include common colds; eye, nose, and throat irritation; allergies; headaches; nausea; COPD; bronchitis; asthma; lung infections; pulmonary disease; autoimmune deficiencies; and cancer.

The positive ripple effects of installing a UV air sterilization system are legion, and many of the benefits are long-term:

• Freeing a workplace from airborne germs, pollutants, and irritants makes for a healthier workforce, and consequently decreases absenteeism and increases productivity.

• UV purification systems have been proven to remove many industry-specific toxic chemicals and volatile organic compounds (VOCs) produced during business operations.

• At 254 nm, the UV light produces no ozone, which can erode copper wiring and tubing. UVC ozone lamps are available that with proper installation, provide air sterilization and odor control.

• UV light prohibits the accumulation of microorganisms, mold, and mildew that can clog the passageways of an AC system, making the motor work harder and shortening the useful life of the mechanics.

• With the destruction of mold and mildew, their associated odors are eliminated.

• The UV germicidal light system lowers energy costs by continuously cleaning the air conditioner components of mold and biofilms, particularly the coils, drain pans, and vent surfaces.

• UV light systems are extremely low maintenance, saving time and money.

• UV systems can work at optimum efficiency throughout a wide range of temperatures, from roughly 40°to 120° F (4° to 48° C). LightSources can custom-design systems to work in higher temperatures as required.

The specific wavelength is proven to be highly effective at eliminating many harmful pathogens, including bacteria, viruses, mold, fungi, and other microorganisms. Germicidal UVC lamps are used in UV air treatment systems, water purification and surface sterilization systems worldwide. 

The standard germicidal lamps, however, cannot be used in the presence of humans due to the risk of damage to human skin and eyes.

222 Nm Far UVC Lamps Are Safer Than Standard Germicidal Lamps

UVC light emitted precisely at 222 nm is also called Far UVC and is proven to have the same germicidal effectiveness without the risk of human exposure. 222 nm UV light is highly absorbed by the DNA of cells, similar to how cells absorb UV light when in the range of 254 nm. 222 nm light is also absorbed by the proteins that surround the cells, which differs from 254 nm light. 

Proteins are contained in the cell outer membranes of bacteria and viruses, and because they absorb 222 nm UV light, the harmful radiation cannot penetrate into the thick layer of human cells. This protective layer is also found on the eyes, making 222 nm light safer for exposure to human skin and eyes, allowing for use in occupied spaces.

Far UVC lamps designed to emit 222 nm are currently in use in many applications, including medical facilities, hospitals, public spaces, and commercial uses providing effective sterilization and disinfection without the risk of causing harm to human health.

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 HVAC Systems for Hospitals and Homes

Ultraviolet light is a powerful disinfectant, sterilizing surfaces, water and air in many environments.  The power of UVC radiation was discovered decades ago and UVC lamps are now found in many sterilization applications, providing quick, effective and cost-efficient sterilization solutions.  The ability for UV light to kill pathogens in air and water was proven scientifically early in the 20th century.  UV lamps have been used in air treatment systems in hospitals since the 1930’s to prevent the spread of diseases including tuberculosis and measles. 

UVC Lamps Kill Many Viruses and Bacteria

UVC lamps replicate the powerful UV electromagnetic radiation from the sun, proven to eliminate harmful viruses, bacteria and pathogens in air and surface sterilization systems.  UVC germicidal lamps are proven to be effective against many types of viruses including influenza (flu), rhinoviruses (common cold), severe acute respiratory syndrome (SARS) and the novel coronavirus (COVID-19).   UV light also eliminates bacteria such as many variations of Streptococcus including Staphylococcus aureus (Staph infection). 

UVC lamps, when properly installed in HVAC systems, are known to prevent the spread of airborne illnesses by destroying viruses on contact.  UV HVAC systems are also known as ultraviolet germicidal irradiation (UVGI) systems and target air contaminants like viruses, bacteria and mold spores.  UV light has the ability to penetrate the DNA of these living organisms and render them unable to replicate which leaves them harmless. 

Commercial and Residential Benefits of UV Lamps in HVAC Systems 

Hospitals and many commercial and industrial applications have been using UV air sterilization systems for decades to disinfect potentially dangerous environments.  UV HVAC systems used in hospitals help to prevent the spread of airborne illnesses in patient rooms, operating rooms and common areas.  UV lamps can be installed in the main HVAC unit aimed at the coils to prevent the spread of contaminants through your heating and cooling system as well as in air ducts.  Stand alone units can be placed in patient bathrooms for further protection in areas known to spread bacteria and viruses. 

UV HVAC systems are becoming more popular in residential homes as many people become aware of the benefits and the ease in which you can disinfect the air in your home.  This is very beneficial to people with compromised immune systems or underlying health conditions, especially respiratory illnesses like asthma.
