摘要
根据发光二极管(LED)设备的光学结构,建立LED封装的数学模型,并给出相应的方程。对于具有均匀矩形光场的LED封装,利用四阶龙格-库塔法,借助Matlab求解出最终的微分方程式,得到其在x、y方向截面曲线的有关数据。然后通过相关软件的建模与仿真,可得到所需的LED均匀矩形光场一次透镜三维模型。该方法实用性强,适于在实际工程应用中广泛推广。
According to the optical structure of LED device,a mathematical model of LED encapsulation is estab- lished and the corresponding equations are given. Taking advantage of Matlab to solve the final differential equation, we obtained some data on the sectional curve of LED encapsulation of homogeneously rectangular irradianee at x,y directions by the fourth order Runge-Kutta method. Then after modeling and simulation by some related software,a 3D model of first lens was obtained which for LED homogeneously rectangular light field. The method has strong function and is suitable for extensive dissemination in the actual engineering applications.
