Luminus releases higher output UVC LEDs
Single device delivers 250mW at 275nm opening new possibilities for disinfection and sterilisation
Luminus Devices, a Sunnyvale-based company that uses technology from the Massachusetts Institute of Technology, has introduced a new, high output UVC LED series.
Called the XFM-5050, the 275nm device is said to set new benchmarks for output, lowering the $/mW another 20 percent compared to previous Luminus UVC LEDs.
The series offers two, three, and four chip options with nominal power levels of 120, 180, and 240 mW of disinfection power. With the industry rapidly transitioning from mercury lamps to LEDs and new applications emerging that require higher power from smaller LEDs, XFM-5050 can deliver more than 400 mW at maximum drive current from a 5mm x 5mm package.
At this new level of power, price, and reliability, even the most challenging applications such as municipal/industrial water purification are within reach, according to the company.
“Effective UVC applications require the right combination of wavelength, intensity, and reliability and the market demands all three at a cost that enables LED adoption,” said Murali Kumar, director of specialty marketing.
“Earlier this year we dropped the cost per milliwatt to $0.10 with the XBT-3535. Lowering the cost an additional 20 percent and increasing output comes just in time to support the rising demand for UVC LED solutions.”
The XFM-5050 series is sampling now, with production volumes starting early in 2021.
