摘要：

In order to enhance the accuracy of lifetime estimation in the LED packages, we developed a multi-channel real-time monitoring system for LED characteristics. This characterizing system includes a precise junction-temperature measurement of the LED packages. A 2,500-hour lifetime test had been carried out and the junction temperatures of the LED packages had been monitored. Our proposing method could consider a deviation of the thermal property in the LED packages and we could filter out thermally-abnormal samples in a lifetime-estimation procedure.
