Modeling Spectral LED Degradation Using an Unsupervised Machine Learning Approach

The modeling of spectral characteristics of light-emitting diodes (LED) has been addressed in various studies. We extend the current state of knowledge by modeling the spectral characteristics of commercially available high-power LEDs, exhibiting a temperature-dependent degradation, by using a diffe...
