LEDLM-80PL LED Optical Aging Test Instrument
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 light source, 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
Features:
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
System Configuration:
1) LED Aging Control System with Arrhenius Software (LM-80PL): it measure total 16 channels on the following curve: photometric VS colorimetric VS power VS temperature VS time. The aging time can be max 10K hours. It can calculate the life according to TM-21.
2) Multiplex Temperature Tester (TMP-16): To measure temperature for 16 channels samples, it can communicate with PC via LM-80PL software
3) Photometric & Colorimetric & Electric Parameters Measurement System: To measure photometric, colorimetric and electric parameters for 16 channels, all the instruments can communicate with PC via LM-80PL software
4) Multi-Channel Power Switch System: to control the power for the test lamp
5) Lamp adapter in High and Low Temperature Chamber: design according to customer's request, max 16pcs.
