LEDLM-80PL LED Lumen Maintenance and Aging Life Test System is
designed according to standards of IES-LM-80, IES-LM-82, TM-21 and
GB2312-80, and the software is developed base on Arrhenius model.
LED has the features of long life, but with the different working
condition and drive current, its life will be different, but
generally the life will be around 50K hours. Differ from the
traditional lightsource, LED light will decay gradually rather than
extinguish instantly, so in the standard of LM-80, it introduces
L70, L50 and etc.
1) L70 (hour): time to 70% lumen maintenance
2) L50 (hour): time to 50% lumen maintenance
1) Record the changing curves of lumen VS time, and colorimetric
parameters VS time
2) Test and record the light attenuation data within a short time,
then software will predict the LED life
3) Introduce the Arrhenius Model to make the test result more
reliable and effective
