CrayoNano UV-C LED lasts over 10,000 hours


Company releases preliminary results of CrayoLED CLH-N3S lifetime results

CrayoNano has released the preliminary results of the CrayoLED CLH-N3S H-Series UV-C LED Room Temperature Operating Life (RTOL) test conducted by an independent, accredited third-party testing and qualification lab.

The lifetime testing aims to demonstrate the quality and reliability of the CrayoLED and generate data to predict the LED’s lifetime until it reaches 70 percent of its original power output based on the TM-21 modelling. The RTOL testing follows the EIAJ-ED-4701/100(101) standard, an industry accepted test method to measure output power maintenance of LED packages.

The CrayoLED CLH-N3S LEDs are tested at the standard forward driving current, 350 mA per LED, under continuous operation for a minimum of 6,000 hours. The test condition and set-up consist of the CLH-N3S LED mounted on an Aluminum Metal Core Printed Circuit Board (MCPCB), attached to an aluminum heatsink for thermal management, and running inside a temperature-controlled chamber.

CrayoNano has demonstrated after 3,000 hours (approximately 4 months), the CLH-N3S UV-C LED at 350 mA has maintained an average performance output of 79.3 percent. This preliminary test data is extrapolated based on the TM-21 model and predicts an estimated lifetime of more than 10,000 hours. This unprecedented lifetime in a small footprint, high-power density UV-C LED will enable solutions in challenging applications requiring better performance and where maintenance is difficult— reducing our customers’ total cost of ownership.

“We have taken great care in creating the CrayoLED —optimizing our LED package design and assembly technology using higher quality materials, combined with our understanding of the thermal efficiencies and performance of LEDs,” says our chief product officer, Alejandro Basauri.

The CrayoLED is optimised for disinfection with a typical peak wavelength of 275 nm. Its small package footprint (3.5 mm x 3.5 mm) and high-power performance (typical 80 mW optical power at 350 mA) are said to easily integrate into systems for residential, commercial, and industrial applications.

CrayoNano will continue testing until the results have reached 6,000 hours to complete the TM-21 testing criteria. Alejandro Basauri continues, “We are immensely proud of the results. Quality and reliability are key factors for solutions towards automated disinfection solutions.”

CrayoLED H-series (CLH-N3S) is available in both sample quantities and in stock for volume production.

Connecting the Compound Semiconductor Industry

The 13th CS International conference builds on the strengths of its predecessors, with around 40 leaders from industry and academia delivering presentations that fall within five key themes: Ultrafast Communication; Making Headway with the MicroLED; Taking the Power from Silicon, New Vectors for the VCSEL, and Ultra-wide Bandgap Devices.

Delegates attending these sessions will gain insight into device technology, find out about the current status and the roadmap for the compound semiconductor industry, and discover the latest advances in tools and processes that will drive up fab yields and throughputs.
