SETi and Psoria-Shield to commercialize Psoria-Light system for UVB phototherapy
Sensor Electronic Technology Inc (SETi) of Columbia, SC, USA, which manufactures deep-ultraviolet (DUV) UVB and UVC LEDs emitting at wavelengths of 230-340nm for healthcare, life science, environmental, military and disinfection applications, has signed a long-term agreement with Psoria-Shield Inc (PSI), a subsidiary of hybrid healthcare company Wellness Center USA Inc, to further develop the UV LED light source used exclusively in the Psoria-Light (PL 1000) system manufactured and sold by PSI. The development is fundamentally based on increasing performance and reducing unit cost.
SETi plans to integrate its new (308nm) LED manufacturing process that emits up to 2mW of UVB power at 20mA drive current in a new high-power light source delivering more than 400mW of optical power. This performance plus associated price/performance improvements aim to enhance the LEDs for UVB dermatology treatments.
PSI is a phototherapy company that has developed, manufactures and distributes the Psoria-Light phototherapy system. The PL 1000 uses targeted high-dosage UV LEDs with both cost and safety benefits to that of a conventional excimer laser, it is claimed. The result is an FDA-cleared system that is said to be simple to use and requires no special laser room, no laser certification or special operator qualifications.
"A major advantage of our LED-based technology is its solid-state reliability and reduced maintenance coupled with it being a class 2 product, which does not require a physician to clinically provide the treatment," says John Yorke, managing director of Psoria Development Corp (PDC). "It can be delivered by office staff and be in compliance with existing billing codes. This allows offices and doctors to be more efficient. We believe the treatment and use of UVB LEDs will become the industry standard," he adds. "The PL 1000 is highly portable and can be moved from room to room, with no special power requirements," Yorke notes.
"Similar improvements have been made to power, lifetime and price/performance to our other 230nm to 340nm LED wavelengths," says SETi's president & CEO Emmanuel Lakios. "Of particular market demand is our germicidal 275nm LEDs."
SETi now believes that - along with its recent in-house increase in wafer capacity, the acquisition of Columbia-based UV LED developer and manufacturer Nitek Inc in December, and its strategic relationship with South Korea's Seoul VioSys (which makes 340-405nm-wavelength UVA LEDs), making SETi the only firm that covers the entire UV spectrum of LEDs from 230nm to 405nm - its LEDs are the most cost-effective, highest-performing products on the market and will see high adoption rates in 2016.
