LED performance analysis under various current waveforms

The paper is addressing an important factor in LED performance, which is the behavior of these devices under various current waveforms, mainly rectangular and triangular types. More, the study is a practical recognition on how LED devices can perform at different switching periods with low frequency ripples in the range of 0 to 100%. The practical measurements are made on three types of LEDs, showing their performance under the same general test conditions.
