An optical system with refraction and total internal reflection was proposed according to the luminous characteristic of LED and the law of energy conservation. The ordinary differential equations satisfying the spots on the contour curve of TIR refractive and reflective planes were established. The coordinates of points on profile curves were obtained by solving these ordinary differential equations using Runge-Kutta method. The profile curves were acquired by curve fitting of the coordinate spots with software UG, and then TIR model of the projector and data of the surface shape suitable for NC manufacture were obtained.
根据LED的发光特性以及能量守恒定律选择采用折射全反射光学系统,通过建立TIR折射面及全反射面轮廓曲线上的点所满足的常微分方程,利用RungeKutta求解常微分方程得到轮廓曲线上点的坐标,再在UG中对坐标点进行曲线拟合得到轮廓曲线,进而得到TIR模型及适合数控加工的面形数据。
