Design and Application of a Rapid Modeling System for Automotive Lamp Optical Patterns
TANG Hongxia
Abstract：To solve the problems of cumbersome process,difficult precision control and low efficiency in traditional automotive lamp light distribution pattern modeling,this paper develops a rapid modeling system for automotive lamp light distribution patterns.It covers four core modules:lamp pattern,electroforming pattern,stripe surface and auxiliary functions,and can realize automatic modeling of 19 types of typical light distribution patterns such as side lamp patterns,pyramid light distribution patterns and honeycomb electroforming patterns.By optimizing the surface offset algorithm,mesh division logic and parametric control process,the system shortens the modeling time of a single type of light distribution pattern to 1/5 of that of the traditional method,and controls the modeling precision error within 0.05mm.Verified by practical engineering cases,the system can meet the needs of the automotive lamp industry for rapid design,accurate modeling and batch reuse of light distribution patterns,and provide key technical support for the optimization of automotive lamp optical performance and the improvement of production efficiency.
