Aging Lifetime & Thermal Resistance Test
LT-300A Aging-Life Test system for LED Luminaires
Meets the measurement requirements of accelerated aging-life related to IES LM82 and IES LM84
LT-300A system is widely used for normal /accelerated aging, lumen maintenance measuring, chromaticity shift measuring, lifetime evaluation and temperature characteristic testing for LED luminaires, arrays, and modules. The extrapolation of lifetime by programmable models is also available to estimate the lifetime of LED luminaires.
Features
- Online Automatic Test
Programmable precision power supply by multi-channels independent & intelligent design, complete real-time online automatic photoelectric parameter testing, making the long and complicated LED product aging, life test and temperature test become very simple and easy. - Accurate and Reliable Long-term Data
The system with self-correction function, without frequent manual correction, greatly improve the efficiency of staff, while long-term data is more accurate and reliable. - Excellent System Integrity
The system contains a number of EVERFINE patented technology so as to lead the level in the world, the whole system design is good, beautiful and generous. - Core Autonomy
This system design refers to the advanced standards and literature such as the American LM-82 standard, and is the crystallization of long-term scientific research of EVERFINE (including the research results of the national 863 program and the doctoral thesis of Zhejiang University under the guidance of Professor Pan, technical director of EVERFINE). - Stable and Reliable Performance
This system has a complete independent intellectual property rights, different from other patchwork devices. It is not only stable and reliable performance on quality, but also guaranteed after-sales service.
