The demand for reliable and energy-efficient LED lighting products has surged in recent years, emphasizing the importance of rigorous testing standards. The LED Lumen Maintenance and Aging Life Test System plays a critical role in evaluating the long-term performance of LED products. This article delves into the principles, methodologies, and significance of LED lumen maintenance and aging tests, with a focus on the LISUN LEDLM-84PL LED Optical Aging Test Instrument.

Introduction to LED Lumen Maintenance and Aging Life Test
The lumen maintenance test measures how well an LED maintains its light output over time. This is critical in predicting the lifespan and efficiency of LED products. Standards such as IES LM-80 and TM-21 provide guidelines for conducting these tests, requiring advanced systems like the LISUN LEDLM-84PL LED Optical Aging Test Instrument for accuracy and compliance.

The aging life test evaluates the durability of LEDs under accelerated environmental conditions, including elevated temperatures, humidity, and electrical stress. This ensures the reliability of LEDs in diverse applications, from residential lighting to industrial installations.

Working Principles of LED Lumen Maintenance and Aging Life Test Systems
The LISUN LEDLM-84PL system integrates advanced optical and thermal management technologies to simulate real-world operating conditions. The testing involves the following steps:

• Initial Measurement: LEDs are evaluated for their initial luminous flux, chromaticity, and color rendering index (CRI).
• Accelerated Aging: LEDs are subjected to continuous operation under specified thermal and electrical conditions.
• Periodic Monitoring: Luminous flux and chromaticity are measured at regular intervals to determine degradation trends.
• Data Analysis: The collected data is extrapolated using TM-21 algorithms to predict the LED’s lifetime at 70% lumen maintenance (L70).
