Product No: LEDLM-84PL
The LEDLM series of LED Optical Aging Test Instrument comprises two models: the LEDLM-80PL and the LEDLM-84PL. The LEDLM-80PL is designed for the R&D and quality inspection of single LEDs or Chips; it is equipped with a DC12010 DC power supply and a GDJW/GW series high-and-low-temperature test chamber. The LEDLM-84PL is intended for the R&D, verification, and incoming quality inspection of complete LED luminaires; it features an LSP-1KVAR AC power supply and a GDJW/GW series high-and-low-temperature test chamber.
The LEDLM series LED Optical Aging Test Instrument supports various lumen maintenance criteria, such as L70 and L50. It enables the simultaneous collection of data on the degradation of optical, chromatic, and electrical performance throughout the aging process of samples. Users can opt for a full 6,000-hour long-term aging test or utilize the Arrhenius acceleration model to project the long-term lifespan of LED products. The system automatically records the changes in luminous flux, color parameters, and electrical parameters over time, and generates standardized lumen maintenance life prediction reports with a single click. It meets the certification testing requirements for lighting products—such as those for ENERGY STAR—and is suitable for use by lighting manufacturers, third-party testing laboratories, and research institutions to conduct reliability assessments of LED light sources and luminaires.
