交流发光二极管（AC-LED）结温的测试方法OACSTPCD
Methodology of Junction Temperature Characterization of Alternating Current Light-Emitting Diodes
目前对交流发光二极管（ AC-LED）的结温测试少有研究。将一种新的电学测试方法---阈值电压法应用到AC-LED结温测试当中，并与传统的峰值波长法进行对比。两种测试方法的结温测试结果相差在4℃之内，有较好的一致性。经过分析，当参考阈值电流为1mA时，阈值电压法的测试误差为±2.5℃，峰值波长法的测试误差为±6℃。阈值电压法测试结果更为精确，应用范围更广，更适用于工业测试。
At present , the measurement techniques of the junction temperatures of light emitting diodes ( LEDs) are developed for AC-LED.In the present work , a novel approach of threshold voltage method is proposed for junction temperature characterization of AC-LEDs.The new method was tested , and results of which were compared with the traditional peak wavelength method , showing a good agreement within 4℃. Further analysis suggested that the error of the threshold…查看全部>>
