【Abstract】 The optical structure of LED was defined and a mathematical model of LED encapsulation and its equation were built.Some data on the sectional curve of LED encapsulation of homogenously rectangular irradiance in x,y directions were obtained through solving the equation above with the method of Runge-Kutta by Matlab.Freeform surface model was built by solidworks and the model was input in Tracepro.The model was modified and some optical simulation was performed by Tracepro,and then the expecting optical model of first lens for LED rectangular radiance was obtained.更多还原
