Abstract：In order to explore the relationship between the structural parameters of the collimating TIR lens and the light intensity and scattering angle,the response surface model is built with the structural parameters as the influencing factors and the light intensity and scattering angle as the response values.The results show that the response surface model has good significance,small variation and high fitting degree.For the prediction data,the maximum average percentage error of light intensity is 0.95%,and the maximum average percentage error of scattering angle is 1.06%,it has good engineering application value.
