UV Lighting: History and Uses

Ultraviolet (UV) light means “beyond violet,” as violet is the highest frequency of light visible to the human eye. The electromagnetic spectrum of light that the human eye can detect is in the range of 380 to 700 nanometers (nm). UV lighting has a shorter wavelength and a higher frequency than visible violet light. 

UV light was first discovered by German physicist Johann Ritter in 1801 when he discovered that invisible light rays darkened paper soaked in silver chloride faster than visible light

UVA, UVB, UVC and Far UVC 

Ultraviolet UV lighting can be categorized into three different areas known as:

UVA – this is the longest wavelength of UV light and is emitted between 320 to 400 nm.   UVA is the least carcinogenic wavelength but still contributes to sunburns and skin cancer.

UVB – light emitted in the wavelength range of 280 to 320 nm is considered UVB. It is more carcinogenic than UVA, however, only about 5% of this light reaches the earth’s surface.

UVC – this is the shortest wavelength of UV light in the range of 100 to 280 nm. UVC light, when emitted from the sun, is the shortest wavelength of light and is completely absorbed by the ozone layer, thus never reaching the earth.  UVC lights are designed to emit UVC radiation, mostly for germicidal applications.

Each category of UV lighting has very useful purposes for many industries and applications. UVA and UVB light are common in many medical phototherapy lamps. UVC light has been known for over a century to possess highly effective sterilization and disinfection properties, particularly at 254 nm.

Far UVC lamps are becoming more popular as they are designed to emit wavelengths close to 222nm, which is found to provide the similar germicidal efficacy to 254 nm lamps while being safe to use in occupied spaces.

UVC Germicidal Lamps

UV lamps designed to emit UVC radiation in the range of 254 nm are used in many germicidal applications, such as UV air purification systems, UV water disinfection, and UV sterilization of surfaces. 

UV Air Purification

UVC lamps have been used for decades to disinfect and remove harmful contaminants from the air, including dust mites, mold spores, viruses, bacteria, fungi, and other harmful airborne microorganisms. UV C air sterilization has a long history of improving indoor air quality and preventing various airborne diseases, as reported by the National Library of Medicine, The History of Ultraviolet Germicidal Irradiation for Air Disinfection.

Ultraviolet germicidal irradiation (UVGI) is used in air purification systems such as Upper Room UVGI and HVAC systems. 

Upper room UVGI systems are designed to disinfect air above occupied spaces in wall or ceiling-mounted UVGI fixtures.  UVC lamps in HVAC systems also disinfect air as it passes through furnaces and AC units to remove harmful airborne contaminants and protect equipment against the buildup of mold and fungi. 

UV Water Disinfection 

UVC lamps provide a highly effective, cost-efficient, and safe alternative to chemical water treatment. UVC lamps are found in many water disinfection systems, such as wastewater treatment for drinking water and industrial water, life sciences and aquaculture, pool and spa applications, and other water treatment applications. 

UV Surface Sterilization

UVC germicidal lamps are also used in many surface sterilization applications to prevent the presence or buildup of harmful microorganisms on surfaces. UV surface sterilization lamps are used in hospitals and medical applications, restaurants, commercial kitchens, and residential products. 

LightSources is an industry-leading global supplier of UV lighting solutions and UV germicidal lamps used in these processes and other germicidal applications. 

UV Medical Phototherapy Lamps

The history of UV light providing therapeutic effects dates back to the early 1900s, with UVA and UVB lamps providing effective treatment to a variety of skin conditions. Specific medical phototherapy lamps must be used for effective treatment and should be prescribed by a physician and used under a doctor’s care. 

UV Tanning Lamps

Ultraviolet lamps designed for tanning beds typically emit UVA radiation, sometimes with a small percentage of UVB. Tanning lamp manufacturers like LightSources offer various innovative lamp designs and proprietary solutions. 

UV Curing Lamps

UV lamps are used in a variety of industrial processes that require curing various coatings, varnishes, lacquers, adhesives, and inks. UV curing provides many benefits to manufacturers with faster curing than air-dried processes and a higher level of quality. UV curing is used in many applications, such as automotive, electrical, optical, and other industrial applications.  LightSources offers various UV curing lamps, including medium pressure, high pressure, and amalgam curing lamps.

UVC Robots Are Making an Appearance in Many Places

UVC robots can vary in shape or size, from small handheld devices that float across countertops to large, autonomous robots that look like a big fancy space heater on wheels. The UVC germicidal lamps mounted to these robots are the key components in providing high levels of sterilization against many known harmful viruses, bacteria and pathogens. In light of current world events, many hospitals began incorporating UVC robots to sterilize patient rooms, bathrooms and hallways and other public places are taking notice.

You might now see a UVC robot making its way through an airport, in schools and on college campuses and are being utilized in jails and correctional facilities.  UVC radiation has long been known to eradicate many harmful germs including serious viruses, bacteria, and superbugs like vancomycin-resistant enterococci (VRE) and Methicillin-resistant Staphylococcus aureus (MRSA).  UVC sterilization lamps are known to kill tuberculosis bacteria as well as SARS, a Cov-2 coronavirus strain. 

UV light emitted in the UVC wavelength precisely between 250 and 260 nm is proven to kill many harmful pathogens quickly and effectively. UV light emitted from roaming UVC robots can disinfect hard to reach places in much less time than it would take for a thorough human cleaning.  Combining standard human disinfection practices with UVC robots, however, is more effective than utilizing only one method of sterilization.

UVC Germicidal Lamps for Ballast Water Treatment Systems

UVC germicidal lamps are proven to be highly effective at sterilizing water, air and surfaces. The recent Ballast Water Treatment Convention, BWTC, requires all shipping companies to maintain an effective ballast water treatment system on board their vessel. When ships pick up ballast water in one port and release it in a foreign port, marine organisms are known to wreak havoc when invading foreign waters.

Marine organisms such as jellyfish and mussels are known to multiply to uncontrollable levels, ruining shipping industries and threatening human safety. Many of these marine organisms are controlled in their natural environment but become dangerous when upsetting the natural ecosystem. Contaminated ballast water is recognized as one of the top five threats to the sustainability of our world’s oceans.

Ultraviolet (UV) technology is proven to sterilize water and eliminate harmful marine organisms such as jellyfish, mussels, viruses, bacteria and microorganisms naked to the human eye. UVC radiation emitted at 254 nanometer (nm) is proven effective at altering the DNA of these living organisms and rendering them harmless. Using the right type of UVC germicidal lamps in your ballast water treatment system is critical to provide the right sterilization and performance.

UVC Germicidal Lamp Ballasts Make the Difference

Selecting the right type of lamp ballasts for UVC germicidal lamps is extremely important in determining lamp performance. Germicidal lamps are active elements in electrical circuits as opposed to passive elements such as inductors, capacitors and resistors. Germicidal lamps, in contrast are active elements because they generate harmonic and transient voltage and current.

Germicidal lamps exhibit a unique characteristic with the voltage decreasing when the current increases. This is referred to as negative AC resistance which makes gas discharge devices inherently unstable. The current would increase without limit once turned on without circuit elements maintaining and restoring operation. These circuit elements are typically called ballasts, which are critical components on UVC germicidal lamps.

How Does a UVC Germicidal Lamps Work?

A UVC germicidal lamp is simply a device which converts electricity into ultraviolet (UV) radiation. Microorganisms are sensitive to ultraviolet radiation emitted at 260 nanometers (nm), which instantly alters the DNA of harmful bacteria and viruses rendering them unable to replicate and harmless. Low-pressure Mercury rare gas UVC lamps convert up to 40% of electrical power into UVC radiation at 254 nm. 

This conversion of electricity is up to 40%, with the quality of the UVC lamp components and construction determining the effectiveness of this conversion of electricity. Low-pressure, mercury rare gas UVC germicidal lamps are very similar to fluorescent lamps. They are similar in construction and operation although UVC germicidal lamps do not have a phosphor coating on the inner lamp wall. This is to allow the most effective wavelength of UVC radiation to flow through the lamp.

UVC Germicidal Lamp Body

The UVC germicidal lamp body may be constructed with pure fused quartz, quartz with titanium, or a soft glass design. Pure fused quartz lamp bodies will transmit both 185 nm and 254 nm of UV radiation with VH glass. A lamp body designed with quartz and titanium blocks out most of the 185 nm radiation in a L glass design. Another L glass design is soft glass also formulated to transmit an effective 254 nm of UVC radiation.

There are electrodes at each end of the lamp which connect the gas discharge device to the external current source. Each electrode serves alternately as either cathode or anode when the lamp is operated on alternating current (AC) as is the typical case. The germicidal lamp body may be filled with a mix of rare gasses including Argon and Neon, or with pure Argon gas depending on the application. A small amount of mercury is required to produce UV radiation.

We provide a wide selection of UVC germicidal lamp products proven in applications worldwide. Contact us to learn more and for custom designed UV lamp solutions to fit your needs.

UV Light Instantly Cures Polymers

Ultraviolet (UV) light is utilized in many industrial and commercial applications to instantly cure, harden and strengthen polymers quickly and effectively. UV light instantly causes a photochemical reaction when exposed to polymers such as epoxies, lacquers, glues, polyurethane and various polymers. UV curing offers many benefits over other drying methods such as air drying or the use of chemicals. 

Benefits of UV Curing

Improved Quality 

UV curing offers many benefits due to the instant drying time which does not allow for evaporation as can occur with air drying. The instant curing provides a more consistent surface with no chance of dust or particles drying in the coating and is smooth compared to air dried surfaces, which produces a higher quality of product. 

Increased Production 

With instant curing, cycle times are increased and productivity is maximized for increased production. UV curing is instant, quicker than air drying or the use of chemicals, which pose additional challenges for companies. 

Safe for Employees 

UV curing is completely safe, with no need to purchase, store or dispose of harmful chemicals. Parts can pass under UV light while on a conveyor or other automated system without the need for employees to apply chemicals which may be hazardous to health. 

All of these benefits equate to increased profitability with a higher level of quality product produced in quicker cycles. Improved quality results in increased customer satisfaction with new and repeat business opportunities.
