Psoria-Shield and SETi unite to help skin disorder sufferers

SETi’s nitride based UVLEDs are used in Psoria‐Light’s patent‐pending emitter, which enables a compact handset to deliver very high power deep UV light in the range from 300 nm to 320 nm.

UV LED manufacturer, Sensor Electronic Technology, Inc. (SETi) has formed a strategic partnership with the manufacturer of the one of the world’s first deep UV LED powered phototherapy systems, Psoria‐Shield Inc.


Psoria‐Shield’s flagship device, the Psoria‐Light benefits from many advantages of LEDs to deliver a high power density of narrow band UV light to treat specific targeted areas of skin conditions including psoriasis, eczema and vitiligo, fast.

SETi UVClean lamps which are multi-chip arrays of UV LEDs enclosed in metal-glass packages

SETi’s UVClean LED array technology has been incorporated into the Psoria‐Light’s patent‐pending emitter, which enables a compact handset to deliver very high power deep UV light in the range from 300 nm to 320 nm; the optimum wavelength range for a variety of phototherapies. Psoria‐Light systems are sold to dermatology healthcare providers for targeted UV phototherapy.

Bulky, high‐voltage class IV laser systems use hazardous gases that need special handling and regeneration, require rigorous safety precautions, and can only be used by operators with specialised medical qualifications. In contrast, Psoria‐Light targeted UV phototherapy is available for use without a warm up period, is compact and user friendly, does not suffer the same safety concerns or require as specialized a healthcare certification to operate.

These benefits significantly reduce cost of ownership for doctors, and that results in improved patient access to this low toxicity, safe and effective therapy. This is only possiblewith UV LEDs that are fast switching (instant on/off), compact, low voltage, easier to integrate into systems, and are environmentally friendly.

Psoria‐Light is the first phototherapy treatment product to be launched with SETi’s UVClean lamps. SETi provides UVTOP LEDs and UVClean products that span the UV wavelength range from 240nm to 355nm in a variety of markets including medical, military, space and industrial for applications that include analysis, imaging, sensing and disinfection.

The UVClean product line includes a wide range of customized UV LED based solutions such as multi‐chip lamps (for high power or multi‐wavelength applications), power supplies, drivers, integrated light sources/modules and full, turn‐key UV LED based systems.

SETi and Psoria‐Shield will be attending MEDICA/ COMPAMED, one of the largest medical trade show exhibitions in the world, November 16th‐ 19th in Dusseldorf, Germany.

SETi will be exhibiting its range of UVClean products and UVTOP LEDs in the COMPAMED at Booth 8AL31.

Psoria‐Shield will be showcasing its next generation technologies at MEDICA in Hall 10 Booth B48.
