SETI drives single chip germicidal UV LED optical output power to a record 100mW

Deep ultraviolet (UV) LED maker Sensor Electronic Technology Inc (SETI) of Columbia, SC, USA says that, in its continuing program to develop UV LEDs for germicidal applications, it has achieved single chip constant current performance of 100mW in the germicidal wavelength range. According to the firm, this achievement exceeds the record for maximum optical power out of a single chip device of this type.

SETI says that although this level of single chip performance is not yet available in its production LEDs, high power UV LED lamps are available under the UVCLEAN trademark with germicidal powers up to 50mW.

“High power UV LEDs are essential to achieve the level of disinfection required in point-of-use and point-of-entry water treatment systems,” said Remis Gaska, president and CEO of SETI. “This ongoing development of large area high power UV LEDs will help to reduce the price per milliwatt and allow UV LEDs to enter cost sensitive disinfection markets.”

Just last week, the firm announced that it had been awarded a $475,000 Small Business Innovation Research (SBIR) Phase II award from the US National Science Foundation (NSF) to develop point-of-use (POU) drinking water disinfection systems based on deep ultraviolet LEDs (DUV LEDs).

SETI will be presenting all the latest data on its high power single chip LEDs at the International Workshop on Nitrides (IWN) in Tampa, Florida, USA (September 19-24).
