一种用于发光二极管结温测量的连续矩形波法

Junction temperature is an important parameter for evaluating thermal property of light-emitting diodes (LEDs). How to accurately measure the junction temperature still remains controversial. In this paper, we propose a continuous rectangular-wave method (CRWM) for measuring the junction temperature of LEDs. This method uses a continuous rectangular wave to drive LED under either voltage mode or c...
