Welcome to LEDs Magazine’s bimonthly UV Tech Insights newsletter for May 11, 2023. We have something different for you in the audience as our featured story this month: an interview with Polarity Medical Technology founder Dr. Tom Chi. It’s safe to say no one has had such an interesting discussion regarding a doorknob in this case, a handle, to be precise since Disney’s animated Alice in Wonderland premiered in 1951. (Fun fact: There is no Doorknob character in the original book, Alice’s Adventures in Wonderland.) Polarity Medical developed the SafeTOUCH UV-C disinfection handle to help eliminate a key contamination point in the fight against healthcare-acquired infections, and hopes to expand its usage in other high-traffic spaces, along with additional antimicrobial devices.

I’d also bring your attention to next week’s webinar with Silanna UV presenting on epitaxy technology for far UV-C that shows promise in increasing UV LED reliability and potentially addressing concerns about UV risks in occupied spaces. We also include a number of industry-provided updates and related technology and applications stories from our colleagues below.

In an interview, TOM CHI, founder of UV disinfection device developer Polarity Medical Technology, explains how a unique form factor could reduce the transmission of pathogens in healthcare and other environments.
Join LEDs Magazine for a May 18 webinar with Silanna UV technical specialists, who will explain how short-period superlattice technology improves UV LEDs emitting 222 nm for disinfection applications.
Writer Kristin Lewotsky learns from market players and experts about misconceptions regarding UV-C LED market prospects and why individual application segment matters in terms of expected growth and timeline.
The new 160-mW LED marks a significant 60% increase over prior Crystal IS devices while retaining the optimal wavelength range (260-270 nm) for germicidal efficacy.
The 280-nm NCSU434C delivers a radiant flux of 110 mW at 350 mA, leading to 5.4% WPE.
Contaminant detection is the focus of a reference design available using Silanna's SF-1 series UV-C LEDs.
The data demonstrates that a set of Klaran LA LEDs operating with a junction temperature of 53°C (soldering point temperature of 35°C) would have a projected L70 lifetime value of over 25,000 hours.
The new line of IoT sensors developed by L-com can monitor light at all levels.
With a growing number of PFAS regulations affecting water suppliers, it is crucial for utilities to understand the ways they can treat these contaminants affordably.
Ultraviolet germicidal irradiation is a mouthful, but read our newest Ask The Expert guide that explains why it should be on the mind of every health-and performance-focused educational leader today.
