摘要：

The reliability analysis of multi-chip LED light sources involves multiple physical fields of light, electricity and heat. The high-precision analysis results will lead to too many calculation resources, too long calculation time and difficult calculation. To solve the above problems, the traditional finite element method(FEM) and efficient artificial neural network(ANN) method are used to analyze the temperature of LED light source, and the advantages and disadvantages of both are discussed. Finally, by combining the advantages of FEM analysis in a single heat transfer physics field with the advantages of ANN in little calculation time and low computational resource requirements, a more efficient method for heat dissipation analysis of multi-chip LED light sources is summarized. Using this method, the correlation coefficient between the prediction data and the training data of ANN reaches 0.997 79, and the prediction result has a good match with the actual heat distribution. The computational resource saves 59% compared with the traditional FEM method. The application of this method can consume fewer computing resources and time based on satisfying the accuracy, while improving the flexibility of analysis. In addition, this method has certain reference value for solving the reliability problems such as the lifetime of high-power LED light source. © 2019, Science Press. All right reserved.
