In practice, one can get luminous flux parameter of LED by off-line measurement method and make prediction of the LED module's service life time. But the prediction results only focus on LED luminous flux, meanwhile colorimetric and thermal characteristics are not involved. Towards to the disadvantage of present LED life time test which only pay attention to the decay of emitting device's luminous flux and efficacy, this paper introduces a kind of innovative LED accelerated life test system and method. During the test, the system can load temperature, humidity, vibration, current and other stress to LED modules in the same time, meanwhile the system can also measure photometric, colorimetric, electrical and thermal parameters of LED modules at the real time of accelerated life test. One can make pre-judgment to the reliability and failure mode of LED module according the variation trend of photometric, colorimetric, electrical and thermal parameters.
