In Duct Air Purification System Provides Health Benefits


In duct air purification systems sanitize and purify the air we breathe, providing many health benefits to people in public and commercial areas.  Air purification systems are used in many HVAC and AC units to deliver clean air free from bacteria, dust, mold and mildew.  These in duct systems are so effective they also eliminate odors from stale air, always giving off a clean fresh scent free from airborne contaminants.

In duct air purification systems are used in settings such as doctor offices, hospitals, grocery stores, restaurants, schools and many other buildings that are open to the public.  Sanitizing the air is especially beneficial in areas where sick people or patients with compromised immune systems may gather.  Children or the elderly are especially susceptible to illness from germs, mold, mildew or contaminants in the air.

UV air purification systems eliminate these volatile compounds from contaminating the air we breathe keeping children, the elderly and the general public safer by providing purified and sanitized air.

UVC Air Purification Systems are Highly Effective

 Ultraviolet (UV) energy in the range of 254 nanometers is highly effective at killing viruses and bacteria.  Most UV air purification systems do not emit ozone as this may corrode the cooling system in AC units by separating the copper lines in the cooling unit from the aluminum fins.  A small amount of ozone emission might be acceptable in certain applications but is not desirable in AC units.

The LightSources group employs experts to assist you in determining the most effective UV air purification system for your unique building structure.  Our vast resources allow us to provide the most sophisticated and technologically advanced lighting solutions at an affordable cost to you, providing a quick return on investment.

Together LightSources in the U.S. and LightTech in Europe are global leaders in the germicidal ultra-violet light industry.  We partner with OEMs of any size to design, engineer and mass-produce new types of proprietary and specialty lamps cost-efficiently and with short turnaround.  Please contact us to learn more about the affordability of high-tech air purification systems.   

Unbreakable Polymer Bond with UV Curing

post 95 UV glue curing is becoming a popular method for many commercial and industrial processes requiring a permanent unbreakable bond in their application.   Often referred to as liquid glue, when sealed with the powerful effects of ultraviolet (UV) radiation, it is more often a polymer rather than glue that provides a strengthened bond.   Often times polyurethane, epoxy or other polymer is used and will dry clear when exposed to UV light.

These specialty polymers harden within seconds of exposure to UV radiation, typically within three seconds although some processes may require additional exposure for maximum adhesion.  Regardless of the time in seconds, this process is considerably less time consuming than applying a chemical coating or other drying methods.

Chemical treatment of manufactured parts requires the purchase of toxic chemicals and ventilation areas for employees applying these volatile compounds.  Bonding with drying takes more time than with UV curing and can also leave inconsistencies in your finished product due to evaporation.

UV Glue Curing Provides Fast and Consistent Bonding

UV glue curing is fast and effective, providing instant hardening with no evaporation or chemical exposure.  Ultraviolet radiation provides effective solutions for large volume production with consistently accurate results.

Curing polymers with UV light provides quick cure rates and allows for specific, targeted applications whether applied to glue or any other various polymers.  The most effective wavelength of UV radiation occurs between 240nm – 270nm, or 350nm to 380nm.

UV Curing Explained – What You Need to Know


Ultraviolet (UV) light is a powerful form of electromagnetic radiation that has been used for decades to cause a reaction to various materials by altering their chemical properties.  UV radiation is not visible to the human eye, with a wavelength in the range of 10 to 400 nm (nanometer) emitting either UVA, UVB, or UVC radiation.

UVA – UVB – UVC Radiation Explained

UVA and UVB radiation is utilized to create a photochemical reaction that instantly dries inks, varnishes, coatings or adhesives and is beneficial in various UV printing or UV drying processes.  UVA light is emitted between 315 and 400nm, with UVB in the range of 280 to 315nm.   The powerful effect that UV radiation causes to materials is fast and efficient, with a hardening or drying process occurring in seconds.  Treating multiple parts in seconds is very cost effective for manufacturers with faster cycle times and increased capacity.

OEM’s around the globe are realizing the benefits of UV curing lamps for enhancing several industries including printing, wood treatment for flooring products, and purification of air and water in sterilization and purification systems.

UVC wavelength is in the range of 200 to 280 nm and is highly effective in sterilization applications used to sanitize either air or water.  UVC germicidal lamps are used in various medical and purification systems, providing clean air in hospitals and sanitary medical equipment.  The LightSources group consists of the leading experts in research and design, engineering and manufacturing the highest performing UV curing lamps in the industry.

New Requirements for Ballast Water Treatment Systems

post 110

The new requirements are here for the Ballast Water Management Convention, taking effect September of 2017 with global enforcement by the Marine Environment Protection Committee (MEPC), a subsidiary group of the International Maritime Organization (IMO).  The main goal of the new convention is to establish procedures and standards for the treatment of ships’ ballast water to prevent the spread of invasive marine organisms from one region to another.

Effective September 8, 2017, new terms of the Convention require all ships sailing through international waters to utilize an effective ballast water treatment system to eliminate the threat of aquatic organisms that may be present in their ballast water.    All ships will be required to have a ballast water treatment plan specific to their ship.  Regulations vary based on the age of the ship and ballast water capacity, although all required systems must be compliant to US Coast Guard Regulations.
