LED in UVC
For a long waiting, Lumex QuasarBrite™ UVC LED is ready for the world. The wavelength is within 265 to 285nm and capable of disinfection.
To accelerate the design of using this UVC LED into products. Lumex provides two different modules, an evaluation board and a demo board, for valuable customers to reduce the time of adapting UVC LED to practical use. Contact Lumex for more details.
The "Anti Micro Activity(%)" results of Lumex Evaluation Board, LDM-LXD3052030UVC, is 98.5(2cm, 30secs, E. coli).* Tested by SGS Taiwan Ltd. with report at June 3rd.
With similar test condition, the performance of Lumex DUO CHIPs UVC LED, SML-LXF3535UVCC10, is better than before.
The "Anti Micro Activity(%)" results of Lumex DUO CHIPs UVC LEDs, SML-LXF3535UVCC10, is 99.9(2cm, 30secs, E. coli). * Tested by SGS Taiwan Ltd. with report at July 13th.
There are lots of benefits of using Lumex QuasarBrite™ UVC LEDs comparing to UVC bulbs/tubes, such as low voltage, low output , low form factor and no mercury.
- Low Operation Volatage - The forward voltage is 6~8 volt. (UVC bulbs/tubes need 40 to 110 volt)
- Low Output
- strong enough to damage DNA or RNA in short distance(within 3cm)
- safe in distance more than 30cm(UV index 1 in 30cm), less than UV dosage in a bright sunny day.
- Low Form Factor - the size of Lumex QuasarBrite™ UVC LED is as tiny as 3.6mm x 3.6mm.
- No Mercury - There are no Mercury used during procution or final componets of Lumex QuasarBrite™ UVC LED.
One of the great news for using UCV LED is the major revision of NSF/ANSI 55(NSF/ANSI 55-2019). According to the news page: Major Revision to Drinking Water Treatment Standard Allows UV-LED Technology to Treat Microorganisms,
- The revision to NSF/ANSI 55: Ultraviolet Microbiological Water Treatment Systems establishes new criteria for use of UV-LED technology for microbial reduction and provides a new test method to certify manufacturer claims.
- “Lab testing shows that ultraviolet LED technology is effective at reducing bacteria and other types of microorganisms in drinking water,” said Jessica Evans, Director of Standards Development at NSF International.
