Disinfection and purification with UV-C LEDs

Clean air, surfaces and water.

Imagine a world in which light makes your everyday life healthier, safer and more pleasant. With UV-C sloutions powered by OSRAM OS, this vision becomes reality.

Light for making our world healthier and improve human well-being is part of our mission. Today like never before current global developments have raised the attention on topics of disinfection and sterilization. Be that at work, at home or on the move, people everywhere are confronted with a new reality and awareness for health and safety.

Today UV-C mercury vapor lamps are used to provide clean water, and surfaces. With UV-C LED solutions - their small and durable design, as well as their mercury free nature, we can extend the use of UV-C Radiation to completely new application areas and overcome obstacles which are currently limiting the broad deployment of UV-C radiation.

After years of R&D and various research projects with leading partners in the industry and the scientific world, OSRAM OS introduces its first LED UV-C products in the low and mid power range.

The OSLON® UV series is designed to provide efficient UV-C radiation for but not limited to medical, home goods and consumer applications. It allows for flexible designs for various types of UV-C applications in the areas of air, water and surface disinfection and purification, as well as treatment or sensing. Design possibilities are endless, and range from point-of-use water treatment, automotive interior disinfection to air purification in portal devices or air conditioning systems.

What is UV-C?

UV radiation is naturally emitted by our sun each day. The spectrum can be sub-divided into UV-A (380-315 nm) UV-B (315-280 nm) and UV-C (280-100 nm). While UV-A and UV-B can reach the surface of the earth, UV-C is absorbed in the atmosphere. Each kind of UV radiation can also be generated artificially and is well used in our daily lives in several applications. While UV-A is widely used in the printing industry or in sensing applications for detecting counterfeit money. And UV-B sources can be deployed in phototherapy or horticulture. UV-C is widely used for disinfection and purification of air, water and surfaces. Typical application areas are water purification for wastewater or in public pools, disinfection of surfaces in hospitals or air purification in air conditioning systems. Depending on the application area different power classes are required to obtain the desired dose on the area or volume of interest.

How does it work?

UV-C radiation is suitable for disinfection of purification since it effectively renders bacteria, viruses and fungi harmless. UV-C radiation has a highly disinfecting effect since UV-C is absorbed by the DNA of microorganisms, inactivating their reproduction process. The dose necessary to achieve a certain inactivation or reduction depends strongly on the application and pathogens targeted.

Why is it so important?

Clean water. Clean air. Clean surfaces. A pure environment where health and safety for everyone is made possible even under the harshest of conditions.

In an interconnected world, new challenges arise such as we have recently been witness to. We are confronted with microorganisms every day. At home and at work, from running an errand, to seeing a physician or the use of plain tab water. The COVID-19 pandemic has lead to a heightened sense of awareness for disinfection and with it a desire for safe UV-C solutions.

UV-C radiation is able to effectively reduce harmful micro-organisms without the use of chemicals.

Advantages

UV-C LED benefits

  • Environmentally friendly: UV-C LEDs are environmentally friendly. In comparison to mercury lamps, UV-C LEDs do not contain mercury.
  • Purification and disinfection without the use of chemicals
  • Flexible design: Due to their small footprint and DC operating feature, they allow for flexible and compact designs.
  • Durability: Compared to mercury lamps, UV-C LEDs are much more robust to mechanical influences as they do not contain fragile glass components.
  • Operation: UV-C LEDs instantly provide full optical output when turned on and stop immediately when switched off. Making cycling at high frequency possible. No pre-heating necessary.
