The system fully meets the requirements of IESNA LM-80. Test and record the aging time and photoelectric maintenance rate of LED like lamp beads and COB, and calculate the service life of LED according to tm-21 standard. There are several typical new advantages for similar products in the market.
1. The semiconductor refrigeration technology is perfectly combined with the optical test, without changing the position of the test sample, so as to avoid the error caused by tester’s operation and the test error caused by different light states caused by the test sample disassembly;
2. It has the independent control of Ts (surface temperature) Ta (environmental temperature), the independent control of multi-channel module within a single interval, the constant temperature of semiconductor electric refrigeration and the bidirectional PID power regulation output, which effectively solves the problem of difficult temperature control of high-power LED. This technology is widely used in the world.
3. The testing LED lamps, independent power supply system, non-interference, and independently control the status of test samples in each circuit. Accurate and reliable data are provided for the study and test of LED life evaluation.
4. Highly automated and integrated testing, including timing testing and inspection testing, and multi-project rectification for optical testing.
