衰减/工作时长测试
LED curing systems use high intensity LEDs which do not require regular replacement, unlike broad-spectrum lamps. At Hanarey, we provide high quality, reliable LEDs, which experience minimal degradation over long periods of use. Longterm life testing of FE-225 systems was conducted for 3,500 continuous hours at 100% intensity.
As noted in the graphs below, LED degradation was found to be very low for the FE-225 with less than 1% per 1,000 hours for all wavelengths. Our high intensity emitters can often lengthen their lifetime by running at intensities below 100%. To extend lifetime even further, LEDs can be turned on and off instantly, with no warm-up period. Contact us for additional details on setting up an LED curing process for maximum throughput and LED die life.
