摘要

本文研究了在流明衰减试验中，LED光源与LED灯具的激活能之间的相关性。采用两种非线性拟合方法验证了不同算法提取活化能的稳定性。结果表明，LED灯具的活化能与LED光源非常接近。LED灯具的活化能通常约为0.20eV，范围为0.18eV至0.23eV，而LED光源的活化能通常为0.17eV，范围为0.11eV至0.26eV。

Correlation of activation energy between LEDs and luminaires in the lumen depreciation test

This paper investigated the correlation of activation energy between LED light source and LED luminaire in lumen depreciation test. Two nonlinear fitting methods were used to verify the stability of the different algorithms to extract the activation energy. The results show that the activation energy of LED luminaire is very close to the LED light source. Activation Energy is typically around 0.20eV and ranges from 0.18eV to 0.23eV for LED luminaire, compared to typically 0.17eV and ranging from 0.11eV to 0.26eV of LED light source.
