Best Articles Continue to Shape Germicidal UV Awareness

As editor Maury Wright reflected earlier this year, the flow of commercial announcements and new ultraviolet germicidal (GUV) products has slowed in recent months. Is the slowdown in supply and logistics related? Is it due to the deployment of COVID-19 vaccines? Or are there other factors at play such as more thoughtful product design cycles, in-depth study of the application and performance of UV emitting devices in action – what do you think? ? The answer may be “all of the above”.

We can hardly report that COVID is defeated, unfortunately. But there are some incredibly determined innovators who continue to solve the problem of the safe and effective application of antimicrobial light solutions to the built environment.

After reviewing our year, we’ve rounded up the four most popular posts we’ve published on GUV this year below. From industry commentary on the transparency of UV-C LED data from manufacturers to an introduction to UV sources and assay capabilities, readers have always flocked to content that provides guidance and perspective for setting the right expectations. both on the market and on the user.

1. Disinfection requires a complete UV-C LED image.

While opening his Last Word contribution with a play to the lyrics of “The Fresh Prince of Bel Air” (Did you get it? Did you get it?), Nichia’s Erik Swenson got down to business, calling out the makers of LEDs to clearly define the UV-C. Specification of strip LEDs (UV-C) and set realistic expectations for their performance in end products and systems.

2. The dose plays an important role in the design of the UV disinfection system.

Although editor-in-chief Maury Wright and I contributed to a blog post in late 2021 on clarifying the terminology used to identify UV radiation measurements, we agree that the content and details of this article authored by Excelitas authors provide a solid introduction to the types of GUV sources. available, their capabilities and drawbacks, and cost comparisons for system design considerations.

3. Education Administrators Struggle with Unknowns in Using UV to Fight COVID-19

The first in our series of special reports on GUV applications focused on educational environments – the current state of technology, UV-C products for integration into building systems and adoption of UV-C based of mercury compared to LED or xenon produced in pilot plants. Maury’s main takeaway here is that containment, reliability, and simple operation of UV-C systems are paramount in a busy academic environment, and they are still far from widespread implementation.

4. Portable UV-C cartridges zap coronavirus on the go

Again, speaking of the containment and safe operation of UV-C emitting products, our Mark Halper reported on a portable air disinfection offer from Osram (now ams Osram) in January 2021. Like us As noted in the past, protecting users and occupants of a space from UV-C radiation is critical as there are exposure limits for human / animal safety. The AirZing UV-Compact cartridge uses a fan to suck the air to be disinfected through a 253.7nm UV-C mercury discharge tube, providing a compact form factor to purify up to a radius of one cubic meter , explains the manufacturer.
