摘要(Abstract):
采用了蒙特卡罗追迹LED灯光子运动,首先构造LED灯光源模型,确定光子运动方向,在光源点至LED灯曲面点之间计算光子频率衰减性,接着分析光子与封装曲面发生弹性散射相函数,材料线性吸收系数,双光子间吸收系数,三光子间吸收系数对光子碰撞的影响,在光子新运动方向确定后对其权重更新,同时大量的光子采用线性同余法产生,最后蒙特卡罗统计光子运动的误差。仿真实验给出了各种光子运动模拟结果,直观地反映了光子特性,为进一步研究复杂的LED灯提供了理论依据。
Monte Carlo tracing LED lighting sub-movement,the first LED light source model constructed to determine the photon direction of motion,in the light point-to-surface point LED light attenuation between the calculation of photon frequency,followed by analysis of photon and packaging flexibility in surface occurs scattering phase function,materials,linear absorption coefficient,between two-photon absorption coefficient,the three-photon absorption coefficient of the photon collision between the impact of the photon direction of motion to determine the new weight after they updated the same time a large number of photons generated using linear congruential method Finally Monte Carlo statistical error of photon movement.Simulation are given a variety of photon motion simulation results,intuitively reflects the photon characteristics,in order to further study the complex LED lights provide a theoretical basis.
