Sensor Electronic Technology doubles efficiency of UVC LEDs
Company now sampling 2.5mW, 265nm to 280nm devices
Sensor Electronics Technology Inc, SETi, a US company specialising in UV LED development and manufacturing, has announced it has shipping samples of its UVC LEDs with 2.5mW of optical power at 265nm toi 280nm.
First launched in August 2013, the 3.5mm x 3.5mm ceramic SMD LEDs have evolved from 0.8mW of power at 20mA to 1.3mW in 2014 and now at 2.5mW, still at 20mA. This product is targeted at cost sensitive, high volume markets such as disinfection.
This announced increase in performance is part of SETi's performance roadmap that builds on developments made through the DARPA CMUVT program. Furthermore the performance represents a doubling of wall-plug efficiency (Pout/Pin) of 2.3 percent (EQE has been measured at 2.9 percent). SETi continues to develop new epitaxial and chip fab processes along with novel packaging techniques.
The 2.5mW UVC LEDs will be exhibited at the SPIE Photonics West exhibition in San Francisco from February 10th - 12th.
