Description

LEDLM-84PL LED Lumen Maintenance and Aging Life Test System is engineered in compliance with IES LM-84 and TM-28 standards. This system performs optical and electrical maintenance testing for LED luminaires, with software utilizing the Arrhenius model and TM-28 methodology for LED life calculation. The LEDLM-84PL requires integration with GDJW Series High and Low Temperature Chamber (optional GW Series) and LSP-1KVARC AC Power Source. View test report samples for LM-84 and TM-28 compliance.

LEDLM-80PL LED Lumen Maintenance and Aging Life Test System is designed to meet IES LM-80 and TM-21 specifications. This instrument conducts optical and electrical maintenance testing for individual LEDs or LED modules, with software employing the Arrhenius model and TM-21 calculations for LED life prediction. The LEDLM-80PL operates in conjunction with GDJW Series High and Low Temperature Chamber (optional GW Series) and DC6010 Series DC Power Source.

LED technology exhibits extended operational life characteristics, though lifespan varies significantly with operating conditions and drive current parameters. Typical service life approximates 50,000 hours. Unlike conventional illumination sources, LED light output demonstrates gradual luminous decay rather than abrupt failure.

Key Performance Metrics:
1) L70 (hours): Time to 70% lumen maintenance
2) L50 (hours): Time to 50% lumen maintenance

Compliance Standards:
• IES LM-84 “Measuring Optical Radiation Maintenance of LED Lamps, Light Engines, and Luminaires”
• IES LM-80 “LED Lumen Maintenance and Aging Life Test”
• LM-79-19 “Optical and Electrical Measurements of Solid State Lighting Products”

Technical Specifications:
• Records temporal variation curves for luminous flux, colorimetric parameters, and electrical characteristics
• Measures light attenuation data within abbreviated test durations, with software-based LED life prediction algorithms
• Incorporates Arrhenius Model methodology for enhanced result reliability and testing efficiency
• LEDLM-84PL test system with LISUN GDJW-015A GDJW Series High and Low Temperature Chamber accommodates simultaneous testing of 8 LED luminaires
