基于蒙特卡罗方法的LED灯光子运动研究

以光子运动为研究对象,首先构造其模型,分析运动的形式,粒子的飞行方向由随机数发生器函数生成,根据菲涅尔透镜公式得出反射率,给出了面元上的能量度。使用随机数判断光子运动最终结果,并且给出了碰幢后的相对光子分布。在用蒙特卡罗方法对光子运动进行模拟时,记录运动的形式利用了焦散光子图和全局光子图。通过实验仿真,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。

Research of LED lamp photon movement based on Monte Carlo method

Take the photon movement as the object of study, but first structure its model, the analysis movement form, the granule flight direction by the random number generator function production, alunite the lens formula obtains the index of reflection according to the Fresnel, gave on the unit of area to be able to measure. Use random number judgment photon movement final outcome, and gave has bumped after the relative photon distribution. When uses the Monte Carlo method carries on the simulation to the photon movement, the recording movement form has used the burnt astigmatism subgraph and the overall situation photon chart. Through the experimental simulation, had reflected intuitively the photon characteristic, for further studied the complex LED lamp to provide the theory basis.
