UV-C LED treatment and purification by ams OSRAM.

Clean water, surfaces and air.

Imagine a world in which light makes your everyday life healthier, safer and more pleasant. With UV-C solutions powered by ams OSRAM, 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 sanitization and purification. 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 robust 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, ams OSRAM offers its UV-C LED products from low to high power.

The OSLON® UV series is designed to provide efficient UV-C radiation for but not limited to 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 sanitization purification, as well as treatment or sensing. Design possibilities are endless and range from point-of-use water treatment, to air purification in portal devices or air conditioning systems.

What is UV-C radiation?

The sun emits optical radiation in form of visible and invisible light. We humans define light as what we can see from the visible spectrum of light, that is, the wavelength between violet (400nm) and dark red (800nm). For the use of light against viruses and germs, the focus is on the range below 400 nanometers, the so-called UV radiation. UV light is divided intro three ranges: UV-A, UV-B and UV-C. The wavelength decreases progressively from 400 to 100 nanometers. Category A ultraviolet sunlight reaches the earth almost unfiltered. UV-A radiation penetrates deep into our skin and causes it to age. UV-B light reaches our upper skin layers and is responsible for sunburn. The short-wave, particularly high-energy UV-C radiation from the sun, on the other hand, is completely absorbed by or ozone layer. There is therefore no natural UV-C radiation on earth. Life on earth has thus developed without being exposed to UV-C radiation. In other words: There was simply no need to develop natural defense mechanisms against UV-C light. This opens special possibilities for science, medicine and technology.

UV-C photons with a wavelength of 200 to 280 nanometers have sufficient energy to alter microbial DNA meaning the exposure to the electromagnetic radiation modifies the genetic material of microorganisms and disrupts their ability to reproduce. As UV-C radiation attacks the helix structure of DNA and RNA it is also effective to inactivate multi-resistant pathogens.

How does it work?

For the use of light to inactivate pathogens, the focus is on invisible light below 400 nanometers, the so-called UV radiation, in particular the Category C ultraviolet light. Although both UV-B and UV-C can harm cells and hence have the capability for sanitization, the extent of the molecular rearrangement of the DNA / RNA by these two radiations is very dissimilar. The shorter the wavelength as more effectively light can penetrate the cells of Microorganisms, therefore UV-C is more suitable to neutralize pathogens. UV-C radiation triggers a photochemical reaction. Depending on the doses of the absorbed UV-C light it modifies the DNA / RNA helix strands by thymine dimer formation, disrupting the pathogen’s capability to replicate and render it harmless.

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 conditions.

In an interconnected world, new challenges arise such as we have recently been witnessing to. We are confronted with pathogens 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 led to a heightened sense of awareness for disinfection and with it a desire for effective UV-C solutions.

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

Advantages

UV-C LED benefits

• UV-C LEDs are environmentally friendly. In comparison to mercury lamps, UV-C LEDs do not contain mercury.
• Purification 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.

Applications

• Horticulture Treatment
• UV-C Treatment
• Sensing
