LT-200A Aging-Life Test system for LEDs
Meets the measurement requirements of accelerated aging-life related to IES LM-80
Typical application scenarios
LT-200A is mainly used for normal aging, accelerated aging test, lumen maintenance characteristic test, life test and temperature characteristic test of single LED and LED module.
The system can monitor the photoelectric parameters and base temperature of the LED sample in real time, process the data, draw the aging curve, and calculate the lifetime exploration of the LED sample.
Main characteristics
1. 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.
2. Accurate and Reliable Long-term Data
Accurate and reliable long-term data system with self-correction function, without frequent manual correction, greatly improve the efficiency of staff, while long-term data is more accurate and reliable.
3. Excellent system integrity
The equipment contains a number of EVERFINE patented technology, the level of the world's leading, the whole equipment design is good, beautiful and generous.
4. Core Autonomy
This system design refers to the advanced standards and literature such as the American LM-80 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).
5. Stable and Reliable
This system has a complete independent intellectual property rights, different from other patchwork systems, not only the quality of the entire system is stable and reliable, after-sales service is also more guaranteed.
