Luminus expands UV LED wavelength options into UVC range
Luminus Devices Inc of Sunnyvale, CA, USA – which designs and makes LEDs and solid-state technology (SST) light sources for illumination markets – has added to its portfolio of UV LEDs by launching its Gen2 XBT-3535 series, with multiple wavelength options including 265nm, 275nm, 285nm, 308nm and 340nm.
The Gen2 XBT-3535 series complements Luminus’s existing UVA and near-UV portfolio, which includes 365nm, 385nm, 395nm, 405nm and 415nm. In a significant expansion into the UVC wavelength range, the XBT-3535 series is now available in 265nm, alongside the previously offered 275nm, specifically tailored for air, water and surface disinfection applications. A lower-power, cost-effective Mini version is also available in 275nm with a power output of 20mW at a current of 150mA.
“What sets the 265nm wavelength apart is its remarkable 56% improvement in disinfection efficiency compared to 280nm, surpassing even the 22% increase achieved with 275nm,” says Murali Kumar, business line director. “Delivering an impressive output power of more than 60mW at 500mA, the XBT-3535 series outperforms its Gen 1 275nm predecessor, in both disinfection performance and cost-effectiveness ($/mW).”
In the UVB range, the XBT-3535 series introduces two options: 285nm and 308nm. Designed for horticulture and analytical instruments, the 285nm variant offers a performance exceeding 85mW at 500mA. On the other hand, the 308nm variant, available in the Mini version, offers a cost-effective solution for phototherapy and horticulture, delivering a power output of more than 30mW at 150mA.
Catering to medical and analytical applications, the XBT-3535 at 340nm provides a powerful 90mW output at 500mA.
Currently, the 265nm, 275nm, and 285nm wavelengths are in production and available, with orders now also being accepted for the 308nm and 340nm variants, slated for production in first-quarter 2024.
