Product No: LEDLM-84PL
LEDLM-80PL LED Lumen Maintenance and Aging Life Test System is designed according to IES-LM-80 and TM-21. It is used to test & record the optical and electrical Maintenance for single LED or LED module. The software is based on Arrhenius model and TM-21 to calculate the LED life. The LEDLM-80PL needs to work with a GDJW/GW Series High Temperature Chamber and and DC12010 DC Power Source. Please click to view the test report samples of LM-80 and TM-21.
LEDLM-84PL LED Lumen Maintenance and Aging Life Test System is designed according to IES LM-84 and TM-28. It is used to test & record the optical and electrical Maintenance for LED luminaires. The software is based on Arrhenius model and TM-28 to calculate the LED life. The LEDLM-84PL needs to work with a GDJW/GW Series High Temperature Chamber and LSP-1KVARC AC Power Source. Please click to view the test report samples of LM-84 and TM-28.
LED has the feature of long life, but its life will be different with the different working condition and driver current. Generally the life will be around 50K hours. Different from the traditional lightsource, LED light will decay gradually rather than extinguish instantly.
1) L70 (hour): time to 70% lumen maintenance
2) L50 (hour): time to 50% lumen maintenance
• Record the changing curves of lumen, colorimetric and electrical parameters VS time
• Test and record the light attenuation data within a short time, then software will predict the LED life
• Introduction to Arrhenius Model, make the final result more reliable and efficient
• LEDLM-80PL/LEDLM-84PL test system can test 8 DUTs one time. (More DUTs can be special designed according to customer’s requirements)
• LEDLM-80PL/LEDLM-84PL test system already inlcudes two sets of testing devices in the temperature chamber.
• The system supply two solutions for LED lumen maintenance and aging test:
1. Strictly according to LM-80 or LM-84 to test up to 6000 hours to get L50 and L70 test report based on TM-21 or TM-28, LISUN LEDLM-80PL/LEDLM-84PL test system will be fully automatic and no need human to operate during 6000hours test.
2. LISUN LEDLM-80PL/LEDLM-84PL test system supply a fast accelerated test. The software was designed based on the Arrhenius Model to simulate 6000 hours testing in a “short time” to get the L50 and L70 test report based on TM-21 or TM-28. This solution saves a lot of time for the testing company.
