Phoseon Surpasses 50,000 Hours of UV LED Lamp Lifetime

Phoseon Technology has achieved a major milestone for UV LED light longevity. Lifetime testing of lamps has now surpassed 50,000 hours of operational on-time with lamp irradiance being greater than 80% of its original output when the test first began five-plus years ago. For perspective, utilizing a single shift workweek of 2,000 hours/year, 50,000 hours equates to 25 years of UV LED operating on-time.

Phoseon maintains over fifty 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.

"Claims of UV LED longevity have been more than validated with these results," stated Phoseon Vice President of Engineering Scott Igl. "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."

In addition to lifetime testing, Phoseon'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.
