RayVio shipping XR 308nm UVB LEDs for phototherapy treatments of skin diseases

Health and hygiene company RayVio Corp of Haywood, CA, USA, which is commercializing deep-ultraviolet (UV) LEDs and consumer disinfection solutions, is shipping its new 308nm-wavelength XR UVB LEDs and supporting the development of phototherapy treatments for skin diseases.

The new XR UV LEDs are said to enable targeted therapies, smaller and lower-cost treatment devices, and high reliability. Available directly from distributor Digi-Key Corp as an emitter or pre-mounted on a star board for easy development and product integration, the new LEDs deliver output power of 13mW at an injection current of 100mA and are rated for up to 10,000 hours of continuous use.

“UV treatment of psoriasis and vitiligo have been limited because of the size and cost of the equipment as well as the risk to healthy surrounding tissue,” says chief innovation officer & co-founder Yitao Liao. “Excimer laser systems address the targeting of treatment to avoid damaging healthy skin, but the systems are bulky and very expensive,” he adds. “Our 308nm UV LEDs are being put into compact, handheld devices that are portable.”

RayVio says that it has achieved record performance of 300mW output at 308nm from a single UV LED package and is already sampling this option to customers. For phototherapy and Vitamin D production, the firm is preparing a more powerful, 293nm emitter in 2019.

RayVio’s work in the UVB range for phototherapy applications complements its UVC LED technology, which can be applied to disinfection and sterilization applications like water purification.
