Temperature Predictions for Automotive Headlamps Using a Coupled Specular Radiation and Natural Convection Model 1999-01-0698

The need to perform thermal analysis for automotive lamps has increased in recent years, due to the use of plastics for the lens and housing materials. Tremendous advances have been made in finite element analysis methods for solving coupled specular surface radiation and natural convection with an unstructured mesh. Headlamp temperature rise predictions were made using the ADINA-F CFD code. The results showed very close agreement between the predicted and measured lens and housing temperatures with an accuracy of +/-10 percent. The successful benchmarking of the lamp thermal model has allowed the analysis method to be applied to a wide variety of lamp designs and operating conditions which has reduced the cost of products and development.
