Test Systems for Life of LED Light Based on Junction Temperature
Abstract:
In order to predict the life of white LED in a short time, three groups constant stress accelerated life tests were conducted by increasing the working current. Life information of LEDs was obtained by using bilinear regression method. The numerical results indicated that the scheme of the accelerated life tests was correct and feasible. The estimation of the LED life was accurate by acceleration parameters．
