Lifetime prediction of a multi-chip high-power LED light source based on artificial neural networks
A high power light-emitting diodes (LED) light source, which is assembled by many LED chips and heat sink, has a not uniform temperature distribution at working condition. Analysis and prediction of a high-power LED system lifetime are complicated and time-consuming.In this study, two artificial neu...
