摘要:
采用遗传算法快捷、准确地优化发光二极管(LED)阵列结构,使其在接收器上(目标平面)的光照分布均匀.推导LED 阵列的照度分布函数,以光照函数标准差与平均差的比值构建一个适应度函数,以此衡量目标平面的光照分布均匀度.获得光照分布最优时的LED 阵列结构数据后,应用MATLAB对几何模型进行仿真.仿真结果表明:目标平面的照度均匀度达到97.4%,验证了所提算法的有效性与可行性.
Abstract:
For obtaining uniform distribution of illumination on the receiver plane(target), the genetic algorithm is used to accurately and quickly optimize the light emitting diode(LED)array. LED array illumination distribution function is derived. A fitness function with the ratio of standard deviation and mean difference of the illumination function is built. The optimal distribution of LED array by applying the light distribution uniformity on the target plane is then achieved. Finally, the geometric model is simulated by using MATLAB. The simulation results show that the illumination uniformity on the target plane reached 97.4% and indicate that the proposed algorithm is feasibility and effectiveness.
