LEDLM-80PL LED constant temperature aging machine with integrateing sphere for testing led life and flux

Introduction:

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

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:
LM-80PL LED Aging Control System with Arrhenius software, TMP-8 Multiplex Temperature Meter, LMS-4000 Quick Test System for Photo and Color, CFO-1.5M Optical Fiber, LS2008R Digital Power Meter, LSP-18CH The Switching Power System for the LED lamp, SLS-50W Standard lamp, CASE-19IN Cabinet

The LEDLM-80PL needs to work with a GDJW Series High and Low Temperature Chamber and an LSP Series AC Power Source.

Design according to IES LM-80 Economic & Flexible.
