Phoseon reaches UV LED lifetime testing milestone

Phoseon Technology maintains over 50 UV LED curing lamps in various stages of lifetime testing at any given time. These light sources are stressed with decreased air flow, high temperatures and other parameters that mimic the harsh working conditions of industrial UV LED curing equipment.

For perspective, the UV LED curing specialist said utilizing a single shift workweek of 2,000 hours per year, 50,000 hours equates to 25 years of UV LED operating on-time.

In addition to lifetime testing, Phoseon Technology's reliability program consists of highly accelerated lifetime testing (HALT), failure modes and effects analysis (FMEA), and a manufacturing burn-in process where each product is built, calibrated, burned-in and recalibrated before customer delivery.

The reliability and development programs are supported by over 200 worldwide patents exclusively devoted to UV LEDs.

‘Claims of UV LED longevity have been more than validated with these results,’ said Scott Igl, vice president of engineering at Phoseon Technology. ‘This 50,000 hour air-cooled lamp showcases our commitment to supplying high-performance, highly reliable light sources.

‘The technology embedded in today's UV LED lamps is built on this foundation so customers can be assured of many years of high-quality UV LED curing.’
